generation. Then he remembers them no more and they cease to be.

Next as regards his own soul. He feels something within him, his life-
power, his will to live, his power to act, his personality--whatever we
like to call it. He cannot touch this thing that is himself, but it is
real. His friend too is alive and one day he is dead; he cannot move, he
cannot act. Well, something has gone that was his friend's self. He has
stopped breathing. Was it his breath? or he is bleeding; is it his blood?
This life-power IS something; does it live in his heart or his lungs or his
midriff? He did not see it go; perhaps it is like wind, an anima, a Geist,
a ghost. But again it comes back in a dream, only looking shadowy; it is
not the man's life, it is a thin copy of the man; it is an "image"
(eidolon). It is like that shifting distorted thing that dogs the living
man's footsteps in the sunshine; it is a "shade" (skia). (The two
conceptions of the soul, as a life-essence, inseparable from the body, and
as a separable phantom seem to occur in most primitive systems. They are
distinct conceptions but are inextricably blended in savage thought. The
two notions Korperseele and Psyche have been very fully discussed in
Wundt's "Volkerpsychologie" II. pages 1-142, Leipzig, 1900.)

Ghosts and sprites, ancestor worship, the soul, oracles, prophecy; all
these elements of the primitive supersensuous world we willingly admit to
be the proper material of religion; but other elements are more surprising;
such are class-names, abstract ideas, numbers, geometrical figures. We do
not nowadays think of these as of religious content, but to primitive men
they were all part of the furniture of his supernatural world.

With respect to class-names, Dr Tylor ("Primitive Culture", Vol. II. page
245 (4th edition), 1903.) has shown how instructive are the first attempts
of the savage to get at the idea of a class. Things in which similarity is
observed, things indeed which can be related at all are to the savage
KINDRED. A species is a family or a number of individuals with a common
god to look after them. Such for example is the Finn doctrine of the
haltia. Every object has its haltia, but the haltiat were not tied to the
individual, they interested themselves in every member of the species.
Each stone had its haltia, but that haltia was interested in other stones;
the individuals disappeared, the haltia remained.

Nor was it only class-names that belonged to the supersensuous world. A
man's own proper-name is a sort of spiritual essence of him, a kind of soul
to be carefully concealed. By pronouncing a name you bring the thing
itself into being. When Elohim would create Day "he called out to the
Light 'Day,' and to the Darkness he called out 'Night'"; the great magician
pronounced the magic Names and the Things came into being. "In the
beginning was the Word" is literally true, and this reflects the fact that
our CONCEPTUAL world comes into being by the mental process of naming. (For
a full discussion of this point see Beck, "Nachahmung" page 41, "Die
Sprache".) In old times people went further; they thought that by naming
events they could bring them to be, and custom even to-day keeps up the
inveterate magical habit of wishing people "Good Morning" and a "Happy

Number, too, is part of the supersensuous world that is thoroughly
religious. We can see and touch seven apples, but seven itself, that
wonderful thing that shifts from object to object, giving it its SEVENness,
that living thing, for it begets itself anew in multiplication--surely
seven is a fit denizen of the upper-world. Originally all numbers dwelt
there, and a certain supersensuous sanctity still clings to seven and
three. We still say "Holy, Holy, Holy," and in some mystic way feel the

The soul and the supersensuous world get thinner and thinner, rarer and
more rarified, but they always trail behind them clouds of smoke and vapour
from the world of sense and space whence they have come. It is difficult
for us even nowadays to use the word "soul" without lapsing into a sensuous
mythology. The Cartesians' sharp distinction between res extensa non
cogitans and res cogitans non extansa is remote.

So far then man, through the processes of his thinking, has provided
himself with a supersensuous world, the world of sense-delusion, of smoke
and cloud, of dream and phantom, of imagination, of name and number and
image. The natural course would now seem to be that this supersensuous
world should develop into the religious world as we know it, that out of a
vague animism with ghosts of ancestors, demons, and the like, there should
develop in due order momentary gods (Augenblicks-Gotter), tribal gods,
polytheism, and finally a pure monotheism.

This course of development is usually assumed, but it is not I think quite
what really happens. The supersensuous world as we have got it so far is
too theoretic to be complete material of religion. It is indeed only one
factor, or rather it is as it were a lifeless body that waits for a living
spirit to possess and inform it. Had the theoretic factor remained
uninformed it would eventually have separated off into its constituent
elements of error and truth, the error dying down as a belated metaphysic,
the truth developing into a correct and scientific psychology of the
subjective. But man has ritual as well as mythology; that is, he feels and
acts as well as thinks; nay more he probably feels and acts long before he
definitely thinks. This contradicts all our preconceived notions of
theology. Man, we imagine, believes in a god or gods and then worships.
The real order seems to be that, in a sense presently to be explained, he
worships, he feels and acts, and out of his feeling and action, projected
into his confused thinking, he develops a god. We pass therefore to our
second factor in religion:--ritual.

The word "ritual" brings to our modern minds the notion of a church with a
priesthood and organised services. Instinctively we think of a
congregation meeting to confess sins, to receive absolution, to pray, to
praise, to listen to sermons, and possibly to partake of sacraments. Were
we to examine these fully developed phenomena we should hardly get further
in the analysis of our religious conceptions than the notion of a highly
anthropomorphic god approached by purely human methods of personal entreaty
and adulation.

Further, when we first come to the study of primitive religions we expect a
priori to find the same elements, though in a ruder form. We expect to see
"The heathen in his blindness bow down to wood and stone," but the facts
that actually confront us are startlingly dissimilar. Bowing down to wood
and stone is an occupation that exists mainly in the minds of hymn-writers.
The real savage is more actively engaged. Instead of asking a god to do
what he wants done, he does it or tries to do it himself; instead of
prayers he utters spells. In a word he is busy practising magic, and above
all he is strenuously engaged in dancing magical dances. When the savage
wants rain or wind or sunshine, he does not go to church; he summons his
tribe and they dance a rain-dance or wind-dance or sun-dance. When a
savage goes to war we must not picture his wife on her knees at home
praying for the absent; instead we must picture her dancing the whole night
long; not for mere joy of heart or to pass the weary hours; she is dancing
his war-dance to bring him victory.

Magic is nowadays condemned alike by science and by religion; it is both
useless and impious. It is obsolete, and only practised by malign
sorcerers in obscure holes and corners. Undoubtedly magic is neither
religion nor science, but in all probability it is the spiritual protoplasm
from which religion and science ultimately differentiated. As such the
doctrine of evolution bids us scan it closely. Magic may be malign and
private; nowadays it is apt to be both. But in early days magic was as
much for good as for evil; it was publicly practised for the common weal.

The gist of magic comes out most clearly in magical dances. We think of
dancing as a light form of recreation, practised by the young from sheer
joie de vivre and unsuitable for the mature. But among the Tarahumares
(Carl Lumholtz, "Unknown Mexico", page 330, London, 1903.) in Mexico the
word for dancing, nolavoa, means "to work." Old men will reproach young
men saying "Why do you not go to work?" meaning why do you not dance
instead of only looking on. The chief religious sin of which the
Tarahumare is conscious is that he has not danced enough and not made
enough tesvino, his cereal intoxicant.

Dancing then is to the savage WORKING, DOING, and the dance is in its
origin an imitation or perhaps rather an intensification of processes of
work. (Karl Bucher, "Arbeit und Rhythmus", Leipzig (3rd edition), 1902,
passim.) Repetition, regular and frequent, constitutes rhythm and rhythm
heightens the sense of will power in action. Rhythmical action may even,
as seen in the dances of Dervishes, produce a condition of ecstasy.
Ecstasy among primitive peoples is a condition much valued; it is often,
though not always, enhanced by the use of intoxicants. Psychologically the
savage starts from the sense of his own will power, he stimulates it by
every means at his command. Feeling his will strongly and knowing nothing
of natural law he recognises no limits to his own power; he feels himself a
magician, a god; he does not pray, he WILLS. Moreover he wills
collectively (The subject of collective hallucination as an element in
magic has been fully worked out by MM. Hubert and Mauss. "Theorie generale
de la Magie", In "L'Annee Sociologique", 1902--3, page 140.), reinforced by
the will and action of his whole tribe. Truly of him it may be said "La
vie deborde l'intelligence, l'intelligence c'est un retrecissement."
(Henri Bergson, "L'Evolution Creatrice", page 50.)

The magical extension and heightening of personality come out very clearly
in what are rather unfortunately known as MIMETIC dances. Animal dances
occur very frequently among primitive peoples. The dancers dress up as
birds, beasts, or fishes, and reproduce the characteristic movements and
habits of the animals impersonated. So characteristic is this
impersonation in magical dancing that among the Mexicans the word for
magic, navali, means "disguise." K. Th. Preuss, "Archiv f.
Religionswissenschaft", 1906, page 97.) A very common animal dance is the
frog-dance. When it rains the frogs croak. If you desire rain you dress
up like a frog and croak and jump. We think of such a performance as a
conscious imitation. The man, we think, is more or less LIKE a frog. That
is not how primitive man thinks; indeed, he scarcely thinks at all; what HE
wants done the frog can do by croaking and jumping, so he croaks and jumps
and, for all he can, BECOMES a frog. "L'intelligence animale JOUE sans
doute les representations plutot qu'elle ne les pense." (Bergson,
"L'Evolution Creatrice", page 205.)

We shall best understand this primitive state of mind if we study the child
"born in sin." If a child is "playing at lions" he does not IMITATE a
lion, i.e. he does not consciously try to be a thing more or less like a
lion, he BECOMES one. His reaction, his terror, is the same as if the real
lion were there. It is this childlike power of utter impersonation, of
BEING the thing we act or even see acted, this extension and
intensification of our own personality that lives deep down in all of us
and is the very seat and secret of our joy in the drama.

A child's mind is indeed throughout the best clue to the understanding of
savage magic. A young and vital child knows no limit to his own will, and
it is the only reality to him. It is not that he wants at the outset to
fight other wills, but that they simply do not exist for him. Like the
artist he goes forth to the work of creation, gloriously alone. His
attitude towards other recalcitrant wills is "they simply must." Let even
a grown man be intoxicated, be in love, or subject to an intense
excitement, the limitations of personality again fall away. Like the
omnipotent child he is again a god, and to him all things are possible.
Only when he is old and weary does he cease to command fate.

The Iroquois (Hewitt, "American Anthropologist", IV. I. page 32, 1902,
N.S.) of North America have a word, orenda, the meaning of which is easier
to describe than to define, but it seems to express the very soul of magic.
This orenda is your power to do things, your force, sometimes almost your
personality. A man who hunts well has much and good orenda; the shy bird
who escapes his snares has a fine orenda. The orenda of the rabbit
controls the snow and fixes the depth to which it will fall. When a storm
is brewing the magician is said to be making its orenda. When you yourself
are in a rage, great is your orenda. The notes of birds are utterances of
their orenda. When the maize is ripening, the Iroquois know it is the
sun's heat that ripens it, but they know more; it is the cigala makes the
sun to shine and he does it by chirping, by uttering his orenda. This
orenda is sometimes very like the Greek thumos, your bodily life, your
vigour, your passion, your power, the virtue that is in you to feel and do.
This notion of orenda, a sort of pan-vitalism, is more fluid than animism,
and probably precedes it. It is the projection of man's inner experience,
vague and unanalysed, into the outer world.

The mana of the Melanesians (Codrington, "The Melanesians", pages 118, 119,
192, Oxford, 1891.) is somewhat more specialised--all men do not possess
mana--but substantially it is the same idea. Mana is not only a force, it
is also an action, a quality, a state, at once a substantive, an adjective,
and a verb. It is very closely neighboured by the idea of sanctity.
Things that have mana are tabu. Like orenda it manifests itself in noises,
but specially mysterious ones, it is mana that is rustling in the trees.
Mana is highly contagious, it can pass from a holy stone to a man or even
to his shadow if it cross the stone. "All Melanesian religion," Dr
Codrington says, "consists in getting mana for oneself or getting it used
for one's benefit." (Codrington, "The Melanesians", page 120, Oxford,

Specially instructive is a word in use among the Omaka (See Prof. Haddon,
"Magic and Fetishism", page 60, London, 1906. Dr Vierkandt ("Globus",
July, 1907, page 41) thinks that "Fernzauber" is a later development from
Nahzauber.), wazhin-dhedhe, "directive energy, to send." This word means
roughly what we should call telepathy, sending out your thought or will-
power to influence another and affect his action. Here we seem to get
light on what has always been a puzzle, the belief in magic exercised at a
distance. For the savage will, distance is practically non-existent, his
intense desire feels itself as non-spatial. (This notion of mana, orenda,
wazhin-dhedhe and the like lives on among civilised peoples in such words
as the Vedic brahman in the neuter, familiar to us in its masculine form
Brahman. The neuter, brahman, means magic power of a rite, a rite itself,
formula, charm, also first principle, essence of the universe. It is own
cousin to the Greek dunamis and phusis. See MM. Hubert et Mauss, "Theorie
generale de la Magie", page 117, in "L'Annee Sociologique", VII.)

Through the examination of primitive ritual we have at last got at one
tangible, substantial factor in religion, a real live experience, the
sense, that is, of will, desire, power actually experienced in person by
the individual, and by him projected, extended into the rest of the world.

At this stage it may fairly be asked, though the question cannot with any
certainty be answered, "at what point in the evolution of man does this
religious experience come in?"

So long as an organism reacts immediately to outside stimulus, with a
certainty and conformity that is almost chemical, there is, it would seem,
no place, no possibility for magical experience. But when the germ appears
of an intellect that can foresee an end not immediately realised, or rather
when a desire arises that we feel and recognise as not satisfied, then
comes in the sense of will and the impulse magically to intensify that
will. The animal it would seem is preserved by instinct from drawing into
his horizon things which do not immediately subserve the conservation of
his species. But the moment man's life-power began to make on the outside
world demands not immediately and inevitably realised in action (I owe this
observation to Dr K. Th. Preuss. He writes ("Archiv f. Relig." 1906, page
98), "Die Betonung des Willens in den Zauberakten ist der richtige Kern.
In der Tat muss der Mensch den Willen haben, sich selbst und seiner
Umgebung besondere Fahigkeiten zuzuschreiben, und den Willen hat er, sobald
ZAUBERHANDLUNGEN NICHT ENSTEHEN." For more detailed analysis of the origin
of magic, see Dr Preuss "Ursprung der Religion und Kunst", "Globus",
LXXXVI. and LXXXVII.), then a door was opened to magic, and in the train of
magic followed errors innumerable, but also religion, philosophy, science
and art.

The world of mana, orenda, brahman is a world of feeling, desiring,
willing, acting. What element of thinking there may be in it is not yet
differentiated out. But we have already seen that a supersensuous world of
thought grew up very early in answer to other needs, a world of sense-
illusions, shadows, dreams, souls, ghosts, ancestors, names, numbers,
images, a world only wanting as it were the impulse of mana to live as a
religion. Which of the two worlds, the world of thinking or the world of
doing, developed first it is probably idle to inquire. (If external
stimuli leave on organisms a trace or record such as is known as an Engram,
this physical basis of memory and hence of thought is almost coincident
with reaction of the most elementary kind. See Mr Francis Darwin's
Presidential Address to the British Association, Dublin, 1908, page 8, and
again Bergson places memory at the very root of conscious existence, see
"L'Evolution Creatrice", page 18, "le fond meme de notre existence
consciente est memoire, c'est a dire prolongation du passee dans le
present," and again "la duree mord dans le temps et y laisse l'enpreint de
son dent," and again, "l'Evolution implique une continuation reelle du
passee par le present.")

It is more important to ask, Why do these two worlds join? Because, it
would seem, mana, the egomaniac or megalomaniac element, cannot get
satisfied with real things, and therefore goes eagerly out to a false
world, the supersensuous other-world whose growth we have sketched. This
junction of the two is fact, not fancy. Among all primitive peoples dead
men, ghosts, spirits of all kinds, become the chosen vehicle of mana. Even
to this day it is sometimes urged that religion, i.e. belief in the
immortality of the soul, is true "because it satisfies the deepest craving
of human nature." The two worlds, of mana and magic on the one hand, of
ghosts and other-world on the other, combine so easily because they have
the same laws, or rather the same comparative absence of law. As in the
world of dreams and ghosts, so in the world of mana, space and time offer
no obstacles; with magic all things are possible. In the one world what
you imagine is real; in the other what you desire is ipso facto
accomplished. Both worlds are egocentric, megalomaniac, filled to the full
with unbridled human will and desire.

We are all of us born in sin, in that sin which is to science "the seventh
and deadliest," anthropomorphism, we are egocentric, ego-projective. Hence
necessarily we make our gods in our own image. Anthropomorphism is often
spoken of in books on religion and mythology as if it were a last climax, a
splendid final achievement in religious thought. First, we are told, we
have the lifeless object as god (fetichism), then the plant or animal
(phytomorphism, theriomorphism), and last God is incarnate in the human
form divine. This way of putting things is misleading. Anthropomorphism
lies at the very beginning of our consciousness. Man's first achievement
in thought is to realise that there is anything at all not himself, any
object to his subject. When he has achieved however dimly this
distinction, still for long, for very long he can only think of those other
things in terms of himself; plants and animals are people with ways of
their own, stronger or weaker than himself but to all intents and purposes

Again the child helps us to understand our own primitive selves. To
children animals are always people. You promise to take a child for a
drive. The child comes up beaming with a furry bear in her arms. You say
the bear cannot go. The child bursts into tears. You think it is because
the child cannot endure to be separated from a toy. It is no such thing.
It is the intolerable hurt done to the bear's human heart--a hurt not to be
healed by any proffer of buns. He wanted to go, but he was a shy, proud
bear, and he would not say so.

The relation of magic to religion has been much disputed. According to one
school religion develops out of magic, according to another, though they
ultimately blend, they are at the outset diametrically opposed, magic being
a sort of rudimentary and mistaken science (This view held by Dr Frazer is
fully set forth in his "Golden Bough" (2nd edition), pages 73-79, London,
1900. It is criticised by Mr R.R. Marett in "From Spell to Prayer", "Folk-
Lore" XI. 1900, page 132, also very fully by MM. Hubert and Mauss, "Theorie
generale de la Magie", in "L'Annee Sociologique", VII. page 1, with Mr
Marett's view and with that of MM. Hubert and Mauss I am in substantial
agreement.), religion having to do from the outset with spirits.

But, setting controversy aside, at the present stage of our inquiry their
relation becomes, I think, fairly clear. Magic is, if my view (This view
as explained above is, I believe, my own most serious contribution to the
subject. In thinking it out I was much helped by Prof. Gilbert Murray.) be
correct, the active element which informs a supersensuous world fashioned
to meet other needs. This blend of theory and practice it is convenient to
call religion. In practice the transition from magic to religion, from
Spell to Prayer, has always been found easy. So long as mana remains
impersonal you order it about; when it is personified and bulks to the
shape of an overgrown man, you drop the imperative and cringe before it.
"My will be done" is magic, "Thy Will be done" is the last word in
religion. The moral discipline involved in the second is momentous, the
intellectual advance not striking.

I have spoken of magical ritual as though it were the informing life-spirit
without which religion was left as an empty shell. Yet the word ritual
does not, as normally used, convey to our minds this notion of intense
vitalism. Rather we associate ritual with something cut and dried, a
matter of prescribed form and monotonous repetition. The association is
correct; ritual tends to become less and less informed by the life-impulse,
more and more externalised. Dr Beck ("Die Nachahmung und ihre Bedeutung
fur Psychologie und Volkerkunde", Leipzig, 1904.) in his brilliant
monograph on "Imitation" has laid stress on the almost boundless influence
of the imitation of one man by another in the evolution of civilisation.
Imitation is one of the chief spurs to action. Imitation begets custom,
custom begets sanctity. At first all custom is sacred. To the savage it
is as much a religious duty to tattoo himself as to sacrifice to his gods.
But certain customs naturally survive, because they are really useful; they
actually have good effects, and so need no social sanction. Others are
really useless; but man is too conservative and imitative to abandon them.
These become ritual. Custom is cautious, but la vie est aleatoire.
(Bergson, op. cit. page 143.)

Dr Beck's remarks on ritual are I think profoundly true and suggestive, but
with this reservation--they are true of ritual only when uninformed by
personal experience. The very elements in ritual on which Dr Beck lays
such stress, imitation, repetition, uniformity and social collectivity,
have been found by the experience of all time to have a twofold influence--
they inhibit the intellect, they stimulate and suggest emotion, ecstasy,
trance. The Church of Rome knows what she is about when she prescribes the
telling of the rosary. Mystery-cults and sacraments, the lineal
descendants of magic, all contain rites charged with suggestion, with
symbols, with gestures, with half-understood formularies, with all the
apparatus of appeal to emotion and will--the more unintelligible they are
the better they serve their purpose of inhibiting thought. Thus ritual
deadens the intellect and stimulates will, desire, emotion. "Les
operations magiques...sont le resultat d'une science et d'une habitude qui
exaltent la volonte humaine au-dessus de ses limites habituelles."
(Eliphas Levi, "Dogme et Rituel de la haute Magie", II. page 32, Paris,
1861, and "A defence of Magic", by Evelyn Underhill, "Fortnightly Review",
1907.) It is this personal EXPERIENCE, this exaltation, this sense of
immediate, non-intellectual revelation, of mystical oneness with all
things, that again and again rehabilitates a ritual otherwise moribund.

To resume. The outcome of our examination of ORIGINES seems to be that
religious phenomena result from two delusive processes--a delusion of the
non-critical intellect, a delusion of the over-confident will. Is religion
then entirely a delusion? I think not. (I am deeply conscious that what I
say here is a merely personal opinion or sentiment, unsupported and perhaps
unsupportable by reason, and very possibly quite worthless, but for fear of
misunderstanding I prefer to state it.) Every dogma religion has hitherto
produced is probably false, but for all that the religious or mystical
spirit may be the only way of apprehending some things and these of
enormous importance. It may also be that the contents of this mystical
apprehension cannot be put into language without being falsified and
misstated, that they have rather to be felt and lived than uttered and
intellectually analysed, and thus do not properly fall under the category
of true or false, in the sense in which these words are applied to
propositions; yet they may be something for which "true" is our nearest
existing word and are often, if not necessary at least highly advantageous
to life. That is why man through a series of more or less grossly
anthropomorphic mythologies and theologies with their concomitant rituals
tries to restate them. Meantime we need not despair. Serious psychology
is yet young and has only just joined hands with physiology. Religious
students are still hampered by mediaevalisms such as Body and Soul, and by
the perhaps scarcely less mythological segregations of Intellect, Emotion,
Will. But new facts (See the "Proceedings" of the Society for Psychical
Research, London, passim, and especially Vols. VII.-XV. For a valuable
collection of the phenomena of mysticism, see William James, "Varieties of
Religious Experience", Edinburgh, 1901-2.) are accumulating, facts about
the formation and flux of personality, and the relations between the
conscious and the sub-conscious. Any moment some great imagination may
leap out into the dark, touch the secret places of life, lay bare the
cardinal mystery of the marriage of the spatial with the non-spatial. It
is, I venture to think, towards the apprehension of such mysteries, not by
reason only, but by man's whole personality, that the religious spirit in
the course of its evolution through ancient magic and modern mysticism is
ever blindly yet persistently moving.

Be this as it may, it is by thinking of religion in the light of evolution,
not as a revelation given, not as a realite faite but as a process, and it
is so only, I think, that we attain to a spirit of real patience and
tolerance. We have ourselves perhaps learnt laboriously something of the
working of natural law, something of the limitations of our human will, and
we have therefore renounced the practice of magic. Yet we are bidden by
those in high places to pray "Sanctify this water to the mystical washing
away of sin." Mystical in this connection spells magical, and we have no
place for a god-magician: the prayer is to us unmeaning, irreverent. Or
again, after much toil we have ceased, or hope we have ceased, to think
anthropomorphically. Yet we are invited to offer formal thanks to God for
a meal of flesh whose sanctity is the last survival of that sacrifice of
bulls and goats he has renounced. Such a ritual confuses our intellect and
fails to stir our emotion. But to others this ritual, magical or
anthropomorphic as it is, is charged with emotional impulse, and others, a
still larger number, think that they act by reason when really they are
hypnotised by suggestion and tradition; their fathers did this or that and
at all costs they must do it. It was good that primitive man in his youth
should bear the yoke of conservative custom; from each man's neck that yoke
will fall, when and because he has outgrown it. Science teaches us to
await that moment with her own inward and abiding patience. Such a
patience, such a gentleness we may well seek to practise in the spirit and
in the memory of Darwin.


By P. GILES, M.A., LL.D. (Aberdeen),
Reader in Comparative Philology in the University of Cambridge.

In no study has the historical method had a more salutary influence than in
the Science of Language. Even the earliest records show that the meaning
of the names of persons, places, and common objects was then, as it has
always been since, a matter of interest to mankind. And in every age the
common man has regarded himself as competent without special training to
explain by inspection (if one may use a mathematical phrase) the meaning of
any words that attracted his attention. Out of this amateur etymologising
has sprung a great amount of false history, a kind of historical mythology
invented to explain familiar names. A single example will illustrate the
tendency. According to the local legend the ancestor of the Earl of
Erroll--a husbandman who stayed the flight of his countrymen in the battle
of Luncarty and won the victory over the Danes by the help of the yoke of
his oxen--exhausted with the fray uttered the exclamation "Hoch heigh!"
The grateful king about to ennoble the victorious ploughman at once

"Hoch heigh! said ye
And Hay shall ye be."

The Norman origin of the name Hay is well-known, and the battle of Luncarty
long preceded the appearance of Normans in Scotland, but the legend
nevertheless persists.

Though the earliest European treatise on philological questions which is
now extant--the "Cratylus" of Plato,--as might be expected from its
authorship, contains some acute thinking and some shrewd guesses, yet the
work as a whole is infantine in its handling of language, and it has been
doubted whether Plato was more than half serious in some of the suggestions
which he puts forward. (For an account of the "Cratylus" with references
to other literature see Sandys' "History of Classical Scholarship", I. page
92 ff., Cambridge, 1903.) In the hands of the Romans things were worse
even than they had been in the hands of Plato and his Greek successors.
The lack of success on the part of Varro and later Roman writers may have
been partly due to the fact that, from the etymological point of view,
Latin is a much more difficult language than Greek; it is by no means so
closely connected with Greek as the ancients imagined, and they had no
knowledge of the Celtic languages from which, on some sides at least, much
greater light on the history of the Latin language might have been
obtained. Roman civilisation was a late development compared with Greek,
and its records dating earlier than 300 B.C.--a period when the best of
Greek literature was already in existence--are very few and scanty. Varro
it is true was much more of an antiquary than Plato, but his extant works
seem to show that he was rather a "dungeon of learning" than an original

A scientific knowledge of language can be obtained only by comparison of
different languages of the same family and the contrasting of their
characteristics with those of another family or other families. It never
occurred to the Greeks that any foreign language was worthy of serious
study. Herodotus and other travellers and antiquaries indeed picked up
individual words from various languages, either as being necessary in
communication with the inhabitants of the countries where they sojourned,
or because of some point which interested them personally. Plato and
others noticed the similarity of some Phrygian words to Greek, but no
systematic comparison seems ever to have been instituted.

In the Middle Ages the treatment of language was in a sense more
historical. The Middle Ages started with the hypothesis, derived from the
book of Genesis, that in the early world all men were of one language and
of one speech. Though on the same authority they believed that the plain
of Shinar has seen that confusion of tongues whence sprang all the
languages upon earth, they seem to have considered that the words of each
separate language were nevertheless derived from this original tongue. And
as Hebrew was the language of the Chosen People, it was naturally assumed
that this original tongue was Hebrew. Hence we find Dante declaring in his
treatise on the Vulgar Tongue (Dante "de Vulgari Eloquio", I. 4.) that the
first word man uttered in Paradise must have been "El," the Hebrew name of
his Maker, while as a result of the fall of Adam, the first utterance of
every child now born into this world of sin and misery is "heu," Alas!
After the splendidly engraved bronze plates containing, as we now know,
ritual regulations for certain cults, were discovered in 1444 at the town
of Gubbio, in Umbria, they were declared, by some authorities, to be
written in excellent Hebrew. The study of them has been the fascination
and the despair of many a philologist. Thanks to the devoted labours of
numerous scholars, mainly in the last sixty years, the general drift of
these inscriptions is now known. They are the only important records of
the ancient Umbrian language, which was related closely to that of the
Samnites and, though not so closely, to that of the Romans on the other
side of the Apennines. Yet less than twenty years ago a book was published
in Germany, which boasts itself the home of Comparative Philology, wherein
the German origin of the Umbrian language was no less solemnly demonstrated
than had been its Celtic origin by Sir William Betham in 1842.

It is good that the study of language should be historical, but the first
requisite is that the history should be sound. How little had been learnt
of the true history of language a century ago may be seen from a little
book by Stephen Weston first published in 1802 and several times reprinted,
where accidental assonance is considered sufficient to establish
connection. Is there not a word "bad" in English and a word "bad" in
Persian which mean the same thing? Clearly therefore Persian and English
must be connected. The conclusion is true, but it is drawn from erroneous
premises. As stated, this identity has no more value than the similar
assonance between the English "cover" and the Hebrew "kophar", where the
history of "cover" as coming through French from a Latin "co-operire" was
even in 1802 well-known to many. To this day, in spite of recent elaborate
attempts (Most recently in H. Moller's "Semitisch und Indogermanisch",
Erster Teil, Kopenhagen, 1907.) to establish connection between the Indo-
Germanic and the Semitic families of languages, there is no satisfactory
evidence of such relation between these families. This is not to deny the
possibility of such a connection at a very early period; it is merely to
say that through the lapse of long ages all trustworthy record of such
relationship, if it ever existed, has been, so far as present knowledge
extends, obliterated.

But while Stephen Weston was publishing, with much public approval, his
collection of amusing similarities between languages--similarities which
proved nothing--the key to the historical study of at least one family of
languages had already been found by a learned Englishman in a distant land.
In 1783 Sir William Jones had been sent out as a judge in the supreme court
of judicature in Bengal. While still a young man at Oxford he was noted as
a linguist; his reputation as a Persian scholar had preceded him to the
East. In the intervals of his professional duties he made a careful study
of the language which was held sacred by the natives of the country in
which he was living. He was mainly instrumental in establishing a society
for the investigation of language and related subjects. He was himself the
first president of the society, and in the "third anniversary discourse"
delivered on February 2, 1786, he made the following observations: "The
Sanscrit language, whatever be its antiquity, is of a wonderful structure;
more perfect than the GREEK, more copious than the LATIN, and more
exquisitely refined than either, yet bearing to both of them a stronger
affinity, both in the roots of verbs and in the forms of grammar, than
could possibly have been produced by accident; so strong indeed, that no
philologer could examine them all three, without believing them to have
sprung from some common source, which, perhaps, no longer exists: there is
a similar reason, though not quite so forcible, for supposing that both the
Gothick and the Celtick, though blended with a very different idiom, had
the same origin with the Sanscrit; and the old Persian might be added to
the same family, if this was the place for discussing any question
concerning the antiquities of Persia." ("Asiatic Researches", I. page 422,
"Works of Sir W. Jones", I. page 26, London, 1799.)

No such epoch-making discovery was probably ever announced with less
flourish of trumpets. Though Sir William Jones lived for eight years more
and delivered other anniversary discourses, he added nothing of importance
to this utterance. He had neither the time nor the health that was needed
for the prosecution of so arduous an undertaking.

But the good seed did not fall upon stony ground. The news was speedily
conveyed to Europe. By a happy chance, the sudden renewal of war between
France and England in 1803 gave Friedrich Schlegel the opportunity of
learning Sanscrit from Alexander Hamilton, an Englishman who, like many
others, was confined in Paris during the long struggle with Napoleon. The
influence of Schlegel was not altogether for good in the history of this
research, but he was inspiring. Not upon him but upon Franz Bopp, a
struggling German student who spent some time in Paris and London a dozen
years later, fell the mantle of Sir William Jones. In Bopp's Comparative
Grammar of the Indo-Germanic languages which appeared in 1833, three-
quarters of a century ago, the foundations of Comparative Philology were
laid. Since that day the literature of the subject has grown till it is
almost, if not altogether, beyond the power of any single man to cope with
it. But long as the discourse may be, it is but the elaboration of the
text that Sir William Jones supplied.

With the publication of Bopp's Comparative Grammar the historical study of
language was put upon a stable footing. Needless to say much remained to
be done, much still remains to be done. More than once there has been
danger of the study following erroneous paths. Its terminology and its
point of view have in some degree changed. But nothing can shake the truth
of the statement that the Indo-Germanic languages constitute in themselves
a family sprung from the same source, marked by the same characteristics,
and differentiated from all other languages by formation, by vocabulary,
and by syntax. The historical method was applied to language long before
it reached biology. Nearly a quarter of a century before Charles Darwin
was born, Sir William Jones had made the first suggestion of a comparative
study of languages. Bopp's Comparative Grammar began to be published nine
years before the first draft of Darwin's treatise on the Origin of Species
was put on paper in 1842.

It is not therefore on the history of Comparative Philology in general that
the ideas of Darwin have had most influence. Unfortunately, as Jowett has
said in the introduction to his translation of Plato's "Republic", most men
live in a corner. The specialisation of knowledge has many advantages, but
it has also disadvantages, none worse perhaps than that it tends to narrow
the specialist's horizon and to make it more difficult for one worker to
follow the advances that are being made by workers in other departments.
No longer is it possible as in earlier days for an intellectual prophet to
survey from a Pisgah height all the Promised Land. And the case of
linguistic research has been specially hard. This study has, if the
metaphor may be allowed, a very extended frontier. On one side it touches
the domain of literature, on other sides it is conterminous with history,
with ethnology and anthropology, with physiology in so far as language is
the production of the brain and tissues of a living being, with physics in
questions of pitch and stress accent, with mental science in so far as the
principles of similarity, contrast, and contiguity affect the forms and the
meanings of words through association of ideas. The territory of
linguistic study is immense, and it has much to supply which might be
useful to the neighbours who border on that territory. But they have not
regarded her even with that interest which is called benevolent because it
is not actively maleficent. As Horne Tooke remarked a century ago, Locke
had found a whole philosophy in language. What have the philosophers done
for language since? The disciples of Kant and of Wilhelm von Humboldt
supplied her plentifully with the sour grapes of metaphysics; otherwise her
neighbours have left her severely alone save for an occasional "Ausflug,"
on which it was clear they had sadly lost their bearings. Some articles in
Psychological Journals, Wundt's great work on "Volkerpsychologie" (Erster
Band: "Die Sprache", Leipzig, 1900. New edition, 1904. This work has
been fertile in producing both opponents and supporters. Delbruck,
"Grundfragen der Sprachforschung", Strassburg, 1901, with a rejoinder by
Wundt, "Sprachgeschichte" and "Sprachpsychologie", Leipzig, 1901; L.
Sutterlin, "Das Wesen der Sprachgebilde", Heidelberg, 1902; von
Rozwadowski, "Wortbildung und Wortbedeutung", Heidelberg, 1904; O.
Dittrich, "Grundzuge der Sprachpsychologie", Halle, 1904, Ch. A. Sechehaye,
"Programme et methodes de la linguistique theorique", Paris, 1908.), and
Mauthner's brilliantly written "Beitrage zu einer Kritik der Sprache" (In
three parts: (i) "Sprache und Psychologie, (ii) "Zur Sprachwissenschaft",
both Stuttgart 1901, (iii) "Zur Grammatic und Logik" (with index to all
three volumes), Stuttgart and Berlin, 1902.) give some reason to hope that,
on one side at least, the future may be better than the past.

Where Charles Darwin's special studies came in contact with the Science of
Language was over the problem of the origin and development of language.
It is curious to observe that, where so many fields of linguistic research
have still to be reclaimed--many as yet can hardly be said to be mapped
out,--the least accessible field of all--that of the Origin of Language--
has never wanted assiduous tillers. Unfortunately it is a field beyond
most others where it may be said that

"Wilding oats and luckless darnel grow."

If Comparative Philology is to work to purpose here, it must be on results
derived from careful study of individual languages and groups of languages.
But as yet the group which Sir William Jones first mapped out and which
Bopp organised is the only one where much has been achieved. Investigation
of the Semitic group, in some respects of no less moment in the history of
civilisation and religion, where perhaps the labour of comparison is not so
difficult, as the languages differ less among themselves, has for some
reason strangely lagged behind. Some years ago in the "American Journal of
Philology" Paul Haupt pointed out that if advance was to be made, it must
be made according to the principles which had guided the investigation of
the Indo-Germanic languages to success, and at last a Comparative Grammar
of an elaborate kind is in progress also for the Semitic languages.
(Brockelmann, "Vergleichende Grammatik der semitischen Sprachen", Berlin,
1907 ff. Brockelmann and Zimmern had earlier produced two small hand-
books. The only large work was William Wright's "Lectures on the
Comparative Grammar of the Semitic Languages", Cambridge, 1890.) For the
great group which includes Finnish, Hungarian, Turkish and many languages
of northern Asia, a beginning, but only a beginning has been made. It may
be presumed from the great discoveries which are in progress in Turkestan
that presently much more will be achieved in this field. But for a certain
utterance to be given by Comparative Philology on the question of the
origin of language it is necessary that not merely for these languages but
also for those in other quarters of the globe, the facts should be
collected, sifted and tabulated. England rules an empire which contains a
greater variety of languages by far than were ever held under one sway
before. The Government of India is engaged in producing, under the
editorship of Dr Grierson, a linguistic survey of India, a remarkable
undertaking and, so far as it has gone, a remarkable achievement. Is it
too much to ask that, with the support of the self-governing colonies, a
similar survey should be undertaken for the whole of the British Empire?

Notwithstanding the great number of books that have been written on the
origin of language in the last three and twenty centuries, the results of
the investigation which can be described as certain are very meagre. The
question originally raised was whether language came into being thesei or
phusei, by convention or by nature. The first alternative, in its baldest
form at least, has passed from out the field of controversy. No one now
claims that names were given to living things or objects or activities by
formal agreement among the members of an early community, or that the first
father of mankind passed in review every living thing and gave it its name.
Even if the record of Adam's action were to be taken literally there would
still remain the question, whence had he this power? Did he develop it
himself or was it a miraculous gift with which he was endowed at his
creation? If the latter, then as Wundt says ("Volkerpsychologie", I. 2,
page 585.), "the miracle of language is subsumed in the miracle of
creation." If Adam developed language of himself, we are carried over to
the alternative origin of phusei. On this hypothesis we must assume that
the natural growth which modern theories of development regard as the
painful progress of multitudinous generations was contracted into the
experience of a single individual.

But even if the origin of language is admitted to be NATURAL there may
still be much variety of signification attached to the word: NATURE, like
most words which are used by philosophers, has accumulated many meanings,
and as research into the natural world proceeds, is accumulating more.

Forty years ago an animated controversy raged among the supporters of the
theories which were named for short the bow-wow, the pooh-pooh and the
ding-dong theories of the origin of language. The third, which was the
least tenacious of life, was made known to the English-speaking world by
the late Professor Max Muller who, however, when questioned, repudiated it
as his own belief. ("Science of Thought", London, 1887, page 211.) It was
taken by him from Heyse's lectures on language which were published
posthumously by Steinthal. Put shortly the theory is that "everything
which is struck, rings. Each substance has its peculiar ring. We can tell
the more or less perfect structure of metals by their vibrations, by the
answer which they give. Gold rings differently from tin, wood rings
differently from stone; and different sounds are produced according to the
nature of each percussion. It may be the same with man, the most highly
organised of nature's work." (Max Muller as above, translating from
Heyse.) Max Muller's repudiation of this theory was, however, not very
whole-hearted for he proceeds later in the same argument: "Heyse's theory,
which I neither adopted nor rejected, but which, as will be seen, is by no
means incompatible with that which for many years has been gaining on me,
and which of late has been so clearly formulated by Professor Noire, has
been assailed with ridicule and torn to pieces, often by persons who did
not even suspect how much truth was hidden behind its paradoxical
appearance. We are still very far from being able to identify roots with
nervous vibrations, but if it should appear hereafter that sensuous
vibrations supply at least the raw material of roots, it is quite possible
that the theory, proposed by Oken and Heyse, will retain its place in the
history of the various attempts at solving the problem of the origin of
language, when other theories, which in our own days were received with
popular applause, will be completely forgotten." ("Science of Thought",
page 212.)

Like a good deal else that has been written on the origin of language, this
statement perhaps is not likely to be altogether clear to the plain man,
who may feel that even the "raw material of roots" is some distance removed
from nervous vibrations, though obviously without the existence of afferent
and efferent nerves articulate speech would be impossible. But Heyse's
theory undoubtedly was that every thought or idea which occurred to the
mind of man for the first time had its own special phonetic expression, and
that this responsive faculty, when its object was thus fulfilled, became
extinct. Apart from the philosophical question whether the mind acts
without external stimulus, into which it is not necessary to enter here, it
is clear that this theory can neither be proved nor disproved, because it
postulates that this faculty existed only when language first began, and
later altogether disappeared. As we have already seen, it is impossible
for us to know what happened at the first beginnings of language, because
we have no information from any period even approximately so remote; nor
are we likely to attain it. Even in their earliest stages the great
families of language which possess a history extending over many centuries
--the Indo-Germanic and the Semitic--have very little in common. With the
exception of Chinese, the languages which are apparently of a simpler or
more primitive formation have either a history which, compared with that of
the families mentioned, is very short, or, as in the case of the vast
majority, have no history beyond the time extending only over a few years
or, at most, a few centuries when they have been observed by competent
scholars of European origin. But, if we may judge by the history of
geology and other studies, it is well to be cautious in assuming for the
first stages of development forces which do not operate in the later,
unless we have direct evidence of their existence.

It is unnecessary here to enter into a prolonged discussion of the other
views christened by Max Muller, not without energetic protest from their
supporters, the bow-wow and pooh-pooh theories of language. Suffice it to
say that the former recognises as a source of language the imitation of the
sounds made by animals, the fall of bodies into water or on to solid
substances and the like, while the latter, also called the interjectional
theory, looks to the natural ejaculations produced by particular forms of
effort for the first beginnings of speech. It would be futile to deny that
some words in most languages come from imitation, and that others, probably
fewer in number, can be traced to ejaculations. But if either of these
sources alone or both in combination gave rise to primitive speech, it
clearly must have been a simple form of language and very limited in
amount. There is no reason to think that it was otherwise. Presumably in
its earliest stages language only indicated the most elementary ideas,
demands for food or the gratification of other appetites, indications of
danger, useful animals and plants. Some of these, such as animals or
indications of danger, could often be easily represented by imitative
sounds: the need for food and the like could be indicated by gesture and
natural cries. Both sources are verae causae; to them Noire, supported by
Max Muller, has added another which has sometimes been called the Yo-heave-
ho theory. Noire contends that the real crux in the early stages of
language is for primitive man to make other primitive men understand what
he means. The vocal signs which commend themselves to one may not have
occurred to another, and may therefore be unintelligible. It may be
admitted that this difficulty exists, but it is not insuperable. The old
story of the European in China who, sitting down to a meal and being
doubtful what the meat in the dish might be, addressed an interrogative
Quack-quack? to the waiter and was promptly answered by Bow-wow,
illustrates a simple situation where mutual understanding was easy. But
obviously many situations would be more complex than this, and to grapple
with them Noire has introduced his theory of communal action. "It was
common effort directed to a common object, it was the most primitive
(uralteste) labour of our ancestors, from which sprang language and the
life of reason." (Noire "Der Ursprung der Sprache", page 331, Mainz,
1877.) As illustrations of such common effort he cites battle cries, the
rescue of a ship running on shore (a situation not likely to occur very
early in the history of man), and others. Like Max Muller he holds that
language is the utterance and the organ of thought for mankind, the one
characteristic which separates man from the brute. "In common action the
word was first produced; for long it was inseparably connected with action;
through long-continued connection it gradually became the firm,
intelligible symbol of action, and then in its development indicated also
things of the external world in so far as the action affected them and
finally the sound began to enter into a connexion with them also." (Op.
cit. page 339.) In so far as this theory recognises language as a social
institution it is undoubtedly correct. Darwin some years before Noire had
pointed to the same social origin of language in the fourth chapter of his
work on "The Expression of the Emotions in Man and Animals". "Naturalists
have remarked, I believe with truth, that social animals, from habitually
using their vocal organs as a means of intercommunication, use them on
other occasions much more freely than other animals...The principle, also,
of association, which is so widely extended in its power, has likewise
played its part. Hence it allows that the voice, from having been employed
as a serviceable aid under certain conditions, inducing pleasure, pain,
rage, etc., is commonly used whenever the same sensations or emotions are
excited, under quite different conditions, or in a lesser degree." ("The
Expression of the Emotions", page 84 (Popular Edition, 1904).

Darwin's own views on language which are set forth most fully in "The
Descent of Man" (page 131 ff. (Popular Edition, 1906).) are characterised
by great modesty and caution. He did not profess to be a philologist and
the facts are naturally taken from the best known works of the day (1871).
In the notes added to the second edition he remarks on Max Muller's denial
of thought without words, "what a strange definition must here be given to
the word thought!" (Op. cit. page 135, footnote 63.) He naturally finds
the origin of language in "the imitation and modification of various
natural sounds, the voices of other animals, and man's own instinctive
cries aided by signs and gestures (op. cit. page 132.)...As the voice was
used more and more, the vocal organs would have been strengthened and
perfected through the principle of the inherited effects of use; and this
would have reacted on the power of speech." (Op. cit. page 133.) On man's
own instinctive cries, he has more to say in "The Expression of the
Emotions". (Page 93 (Popular Edition, 1904) and elsewhere.) These remarks
have been utilised by Prof. Jespersen of Copenhagen in propounding an
ingenious theory of his own to the effect that speech develops out of
singing. ("Progress in Language", page 361, London, 1894.)

For many years and in many books Max Muller argued against Darwin's views
on evolution on the one ground that thought is impossible without speech;
consequently as speech is confined to the human race, there is a gulf which
cannot be bridged between man and all other creatures. (Some interesting
comments on the theory will be found in a lecture on "Thought and Language"
in Samuel Butler's "Essays on Life, Art and Science", London, 1908.) On
the title-page of his "Science of Thought" he put the two sentences "No
Reason without Language: No Language without Reason." It may be readily
admitted that the second dictum is true, that no language properly so-
called can exist without reason. Various birds can learn to repeat words
or sentences used by their masters or mistresses. In most cases probably
the birds do not attach their proper meaning to the words they have learnt;
they repeat them in season and out of season, sometimes apparently for
their own amusement, generally in the expectation, raised by past
experience, of being rewarded for their proficiency. But even here it is
difficult to prove a universal negative, and most possessors of such pets
would repudiate indignantly the statement that the bird did not understand
what was said to it, and would also contend that in many cases the words
which it used were employed in their ordinary meaning. The first dictum
seems to be inconsistent with fact. The case of deaf mutes, such as Laura
Bridgeman, who became well educated, or the still more extraordinary case
of Helen Keller, deaf, dumb, and blind, who in spite of these disadvantages
has learnt not only to reason but to reason better than the average of
persons possessed of all their senses, goes to show that language and
reason are not necessarily always in combination. Reason is but the
conscious adaptation of means to ends, and so defined is a faculty which
cannot be denied to many of the lower animals. In these days when so many
books on Animal Intelligence are issued from the press, it seems
unnecessary to labour the point. Yet none of these animals, except by
parrot-imitation, makes use of speech, because man alone possesses in a
sufficient degree of development the centres of nervous energy which are
required for the working of articulation in speech. On this subject much
investigation was carried on during the last years of Darwin's life and
much more in the period since his death. As early as 1861 Broca, following
up observations made by earlier French writers, located the centre of
articulate speech in the third left frontal convolution of the brain. In
1876 he more definitely fixed the organ of speech in "the posterior two-
fifths of the third frontal convolution" (Macnamara, "Human Speech", page
197, London, 1908.), both sides and not merely the left being concerned in
speech production. Owing however to the greater use by most human beings
of the right side of the body, the left side of the brain, which is the
motor centre for the right side of the body, is more highly developed than
its right side, which moves the left side of the body. The investigations
of Professors Ferrier, Sherrington and Grunbaum have still more precisely
defined the relations between brain areas and certain groups of muscles.
One form of aphasia is the result of injury to or disease in the third
frontal convolution because the motor centre is no longer equal to the task
of setting the necessary muscles in motion. In the brain of idiots who are
unable to speak, the centre for speech is not developed. (Op. cit. page
226.) In the anthropoid apes the brain is similarly defective, though it
has been demonstrated by Professors Cunningham and Marchand "that there is
a tendency, especially in the gorilla's brain, for the third frontal
convolution to assume the human form...But if they possessed a centre for
speech, those parts of the hemispheres of their brains which form the
mechanism by which intelligence is elaborated are so ill-developed, as
compared with the rest of their bodies, that we can not conceive, even with
more perfect frontal convolutions, that these animals could formulate ideas
expressible in intelligent speech." (Op. cit. page 223.)

While Max Muller's theory is Shelley's

"He gave man speech, and speech created thought,
Which is the measure of the universe" ("Prometheus Unbound" II. 4.),

it seems more probable that the development was just the opposite--that the
development of new activities originated new thoughts which required new
symbols to express them, symbols which may at first have been, even to a
greater extent than with some of the lower races at present, sign language
as much as articulation. When once the faculty of articulation was
developed, which, though we cannot trace the process, was probably a very
gradual growth, there is no reason to suppose that words developed in any
other way then they do at present. An erroneous notion of the development
of language has become widely spread through the adoption of the
metaphorical term "roots" for the irreducible elements of human speech.
Men never talked in roots; they talked in words. Many words of kindred
meaning have a part in common, and a root is nothing but that common part
stripped of all additions. In some cases it is obvious that one word is
derived from another by the addition of a fresh element; in other cases it
is impossible to say which of two kindred words is the more primitive. A
root is merely a convenient term for an abstraction. The simplest word may
be called a root, but it is nevertheless a word. How are new words added
to a language in the present day? Some communities, like the Germans,
prefer to construct new words for new ideas out of the old material
existing in the language; others, like the English, prefer to go to the
ancient languages of Greece and Rome for terms to express new ideas. The
same chemical element is described in the two languages as sour stuff
(Sauerstoff) and as oxygen. Both terms mean the same thing etymologically
as well as in fact. On behalf of the German method, it may be contended
that the new idea is more closely attached to already existing ideas, by
being expressed in elements of the language which are intelligible even to
the meanest capacity. For the English practice it may be argued that, if
we coin a new word which means one thing, and one thing only, the idea
which it expresses is more clearly defined than if it were expressed in
popularly intelligible elements like "sour stuff." If the etymological
value of words were always present in the minds of their users, "oxygen"
would undoubtedly have an advantage over "sour stuff" as a technical term.
But the tendency in language is to put two words of this kind which express
but one idea under a single accent, and when this has taken place, no one
but the student of language any longer observes what the elements really
mean. When the ordinary man talks of a "blackbird" it is certainly not
present to his consciousness that he is talking of a black bird, unless for
some reason conversation has been dwelling upon the colour rather than
other characteristics of the species.

But, it may be said, words like "oxygen" are introduced by learned men, and
do not represent the action of the man in the street, who, after all, is
the author of most additions to the stock of human language. We may go
back therefore some four centuries to a period, when scientific study was
only in its infancy, and see what process was followed. With the discovery
of America new products never seen before reached Europe, and these
required names. Three of the most characteristic were tobacco, the potato,
and the turkey. How did these come to be so named? The first people to
import these products into Europe were naturally the Spanish discoverers.
The first of these words--tobacco--appears in forms which differ only
slightly in the languages of all civilised countries: Spanish tabaco,
Italian tabacco, French tabac, Dutch and German tabak, Swedish tobak, etc.
The word in the native dialect of Hayti is said to have been tabaco, but to
have meant not the plant (According to William Barclay, "Nepenthes, or the
Virtue of Tobacco", Edinburgh, 1614, "the countrey which God hath honoured
and blessed with this happie and holy herbe doth call it in their native
language 'Petum'.") but the pipe in which it was smoked. It thus
illustrates a frequent feature of borrowing--that the word is not borrowed
in its proper signification, but in some sense closely allied thereto,
which a foreigner, understanding the language with difficulty, might
readily mistake for the real meaning. Thus the Hindu practice of burning a
wife upon the funeral pyre of her husband is called in English "suttee",
this word being in fact but the phonetic spelling of the Sanskrit "sati",
"a virtuous woman," and passing into its English meaning because formerly
the practice of self-immolation by a wife was regarded as the highest

The name of the potato exhibits greater variety. The English name was
borrowed from the Spanish "patata", which was itself borrowed from a native
word for the "yam" in the dialect of Hayti. The potato appeared early in
Italy, for the mariners of Genoa actively followed the footsteps of their
countryman Columbus in exploring America. In Italian generally the form
"patata" has survived. The tubers, however, also suggested a resemblance
to truffles, so that the Italian word "tartufolo", a diminutive of the
Italian modification of the Latin "terrae tuber" was applied to them. In
the language of the Rhaetian Alps this word appears as "tartufel". From
there it seems to have passed into Germany where potatoes were not
cultivated extensively till the eighteenth century, and "tartufel" has in
later times through some popular etymology been metamorphosed into
"Kartoffel". In France the shape of the tubers suggested the name of
earth-apple (pomme de terre), a name also adopted in Dutch (aard-appel),
while dialectically in German a form "Grumbire" appears, which is a
corruption of "Grund-birne", "ground pear". (Kluge "Etymologisches
Worterbuch der deutschen Sprache" (Strassburg), s.v. "Kartoffel".) Here
half the languages have adopted the original American word for an allied
plant, while others have adopted a name originating in some more or less
fanciful resemblance discovered in the tubers; the Germans alone in Western
Europe, failing to see any meaning in their borrowed name, have modified it
almost beyond recognition. To this English supplies an exact parallel in
"parsnep" which, though representing the Latin "pastinaca" through the Old
French "pastenaque", was first assimilated in the last syllable to the
"nep" of "turnep" ("pasneppe" in Elizabethan English), and later had an "r"
introduced into the first syllable, apparently on the analogy of "parsley".

The turkey on the other hand seems never to be found with its original
American name. In England, as the name implies, the turkey cock was
regarded as having come from the land of the Turks. The bird no doubt
spread over Europe from the Italian seaports. The mistake, therefore, was
not unnatural, seeing that these towns conducted a great trade with the
Levant, while the fact that America when first discovered was identified
with India helped to increase the confusion. Thus in French the "coq
d'Inde" was abbreviated to "d'Inde" much as "turkey cock" was to "turkey";
the next stage was to identify "dinde" as a feminine word and create a new
"dindon" on the analogy of "chapon" as the masculine. In Italian the name
"gallo d'India" besides survives, while in German the name "Truthahn" seems
to be derived onomatopoetically from the bird's cry, though a dialectic
"Calecutischer Hahn" specifies erroneously an origin for the bird from the
Indian Calicut. In the Spanish "pavo", on the other hand, there is a
curious confusion with the peacock. Thus in these names for objects of
common knowledge, the introduction of which into Europe can be dated with
tolerable definiteness, we see evinced the methods by which in remoter ages
objects were named. The words were borrowed from the community whence came
the new object, or the real or fancied resemblance to some known object
gave the name, or again popular etymology might convert the unknown term
into something that at least approached in sound a well-known word.

"The Origin of Species" had not long been published when the parallelism of
development in natural species and in languages struck investigators. At
the time, one of the foremost German philologists was August Schleicher,
Professor at Jena. He was himself keenly interested in the natural
sciences, and amongst his colleagues was Ernst Haeckel, the protagonist in
Germany of the Darwinian theory. How the new ideas struck Schleicher may
be seen from the following sentences by his colleague Haeckel. "Speech is
a physiological function of the human organism, and has been developed
simultaneously with its organs, the larynx and tongue, and with the
functions of the brain. Hence it will be quite natural to find in the
evolution and classification of languages the same features as in the
evolution and classification of organic species. The various groups of
languages that are distinguished in philology as primitive, fundamental,
parent, and daughter languages, dialects, etc., correspond entirely in
their development to the different categories which we classify in zoology
and botany as stems, classes, orders, families, genera, species and
varieties. The relation of these groups, partly coordinate and partly
subordinate, in the general scheme is just the same in both cases; and the
evolution follows the same lines in both." (Haeckel, "The Evolution of
Man", page 485, London, 1905. This represents Schleicher's own words: Was
die Naturforscher als Gattung bezeichnen wurden, heisst bei den Glottikern
Sprachstamm, auch Sprachsippe; naher verwandte Gattungen bezeichnen sie
wohl auch als Sprachfamilien einer Sippe oder eines Sprachstammes...Die
Arten einer Gattung nennen wir Sprachen eines Stammes; die Unterarten einer
Art sind bei uns die Dialekte oder Mundarten einer Sprache; den Varietaten
und Spielarten entsprechen die Untermundarten oder Nebenmundarten und
endlich den einzelnen Individuen die Sprechweise der einzelnen die Sprachen
redenden Menschen. "Die Darwinische Theorie und die Sprachwissenschaft",
Weimar, 1863, page 12 f. Darwin makes a more cautious statement about the
classification of languages in "The Origin of Species", page 578, (Popular
Edition, 1900).) These views were set forth in an open letter addressed to
Haeckel in 1863 by Schleicher entitled, "The Darwinian theory and the
science of language". Unfortunately Schleicher's views went a good deal
farther than is indicated in the extract given above. He appended to the
pamphlet a genealogical tree of the Indo-Germanic languages which, though
to a large extent confirmed by later research, by the dichotomy of each
branch into two other branches, led the unwary reader to suppose their
phylogeny (to use Professor Haeckel's term) was more regular than our
evidence warrants.

Without qualification Schleicher declared languages to be "natural
organisms which originated unconditioned by the human will, developed
according to definite laws, grow old and die; they also are characterised
by that series of phenomena which we designate by the term 'Life.'
Consequently Glottic, the science of language, is a natural science; its
method is in general the same as that of the other natural sciences."
("Die Darwinische Theorie", page 6 f.) In accordance with this view he
declared (op. cit. page 23.) that the root in language might be compared
with the simple cell in physiology, the linguistic simple cell or root
being as yet not differentiated into special organs for the function of
noun, verb, etc.

In this probably all recent philologists admit that Schleicher went too
far. One of the most fertile theories in the modern science of language
originated with him, and was further developed by his pupil, August Leskien
("Die Declination im Slavisch-litanischen und Germanischen", Leipzig, 1876;
Osthoff and Brugmann, "Morphologische Untersuchungen", I. (Introduction),
1878. The general principles of this school were formulated (1880) in a
fuller form in H. Paul's "Prinzipien der Sprachgeschichte", Halle (3rd
edition, 1898). Paul and Wundt (in his "Volkerpsychologie") deal largely
with the same matter, but begin their investigations from different points
of view, Paul being a philologist with leanings to philosophy and Wundt a
philosopher interested in language.), and by Leskien's colleagues and
friends, Brugmann and Osthoff. This was the principle that phonetic laws
have no exceptions. Under the influence of this generalisation much
greater precision in etymology was insisted upon, and a new and remarkably
active period in the study of language began. Stated broadly in the
fashion given above the principle is not true. A more accurate statement
would be that an original sound is represented in a given dialect at a
given time and in a given environment only in one way; provided that the
development of the original sound into its representation in the given
dialect has not been influenced by the working of analogy.

It is this proviso that is most important for the characterisation of the
science of language. As I have said elsewhere, it is at this point that
this science parts company with the natural sciences. "If the chemist
compounds two pure simple elements, there can be but one result, and no
power of the chemist can prevent it. But the minds of men do act upon the
sounds which they produce. The result is that, when this happens, the
phonetic law which would have acted in the case is stopped, and this
particular form enters on the same course of development as other forms to
which it does not belong." (P. Giles, "Short Manual of Comparative
Philology", 2nd edition, page 57, London, 1901.)

Schleicher was wrong in defining a language to be an organism in the sense
in which a living being is an organism. Regarded physiologically, language
is a function or potentiality of certain human organs; regarded from the
point of view of the community it is of the nature of an institution.
(This view of language is worked out at some length by Prof. W.D. Whitney
in an article in the "Contemporary Review" for 1875, page 713 ff. This
article forms part of a controversy with Max Muller, which is partly
concerned with Darwin's views on language. He criticises Schleicher's
views severely in his "Oriental and Linguistic Studies", page 298 ff., New
York, 1873. In this volume will be found criticisms of various other views
mentioned in this essay.) More than most influences it conduces to the
binding together of the elements that form a state. That geographical or
other causes may effectively counteract the influence of identity of
language is obvious. One need only read the history of ancient Greece, or
observe the existing political separation of Germany and Austria, of Great
Britain and the United States of America. But however analogous to an
organism, language is not an organism. In a less degree Schleicher, by
defining languages as such, committed the same mistake which Bluntschli
made regarding the State, and which led him to declare that the State is by
nature masculine and the Church feminine. (Bluntschli, "Theory of the
State", page 24, Second English Edition, Oxford, 1892.) The views of
Schleicher were to some extent injurious to the proper methods of
linguistic study. But this misfortune was much more than fully compensated
by the inspiration which his ideas, collected and modified by his
disciples, had upon the science. In spite of the difference which the
psychological element represented by analogy makes between the science of
language and the natural sciences, we are entitled to say of it as
Schleicher said of Darwin's theory of the origin of species, "it depends
upon observation, and is essentially an attempt at a history of

Other questions there are in connection with language and evolution which
require investigation--the survival of one amongst several competing words
(e.g. why German keeps only as a high poetic word "ross", which is
identical in origin with the English work-a-day "horse", and replaces it by
"pferd", whose congener the English "palfrey" is almost confined to poetry
and romance), the persistence of evolution till it becomes revolution in
languages like English or Persian which have practically ceased to be
inflectional languages, and many other problems. Into these Darwin did not
enter, and they require a fuller investigation than is possible within the
limits of the present paper.

1. Evolution, and the principles associated with the Darwinian theory,
could not fail to exert a considerable influence on the studies connected
with the history of civilised man. The speculations which are known as
"philosophy of history," as well as the sciences of anthropology,
ethnography, and sociology (sciences which though they stand on their own
feet are for the historian auxiliary), have been deeply affected by these
principles. Historiographers, indeed, have with few exceptions made little
attempt to apply them; but the growth of historical study in the nineteenth
century has been determined and characterised by the same general principle
which has underlain the simultaneous developments of the study of nature,
namely the GENETIC idea. The "historical" conception of nature, which has
produced the history of the solar system, the story of the earth, the
genealogies of telluric organisms, and has revolutionised natural science,
belongs to the same order of thought as the conception of human history as
a continuous, genetic, causal process--a conception which has
revolutionised historical research and made it scientific. Before
proceeding to consider the application of evolutional principles, it will
be pertinent to notice the rise of this new view.

2. With the Greeks and Romans history had been either a descriptive record
or had been written in practical interests. The most eminent of the
ancient historians were pragmatical; that is, they regarded history as an
instructress in statesmanship, or in the art of war, or in morals. Their
records reached back such a short way, their experience was so brief, that
they never attained to the conception of continuous process, or realised
the significance of time; and they never viewed the history of human
societies as a phenomenon to be investigated for its own sake. In the
middle ages there was still less chance of the emergence of the ideas of
progress and development. Such notions were excluded by the fundamental
doctrines of the dominant religion which bounded and bound men's minds. As
the course of history was held to be determined from hour to hour by the
arbitrary will of an extra-cosmic person, there could be no self-contained
causal development, only a dispensation imposed from without. And as it
was believed that the world was within no great distance from the end of
this dispensation, there was no motive to take much interest in
understanding the temporal, which was to be only temporary.

The intellectual movements of the fifteenth and sixteenth centuries
prepared the way for a new conception, but it did not emerge immediately.
The historians of the Renaissance period simply reverted to the ancient
pragmatical view. For Machiavelli, exactly as for Thucydides and Polybius,
the use of studying history was instruction in the art of politics. The
Renaissance itself was the appearance of a new culture, different from
anything that had gone before; but at the time men were not conscious of
this; they saw clearly that the traditions of classical antiquity had been
lost for a long period, and they were seeking to revive them, but otherwise
they did not perceive that the world had moved, and that their own spirit,
culture, and conditions were entirely unlike those of the thirteenth
century. It was hardly till the seventeenth century that the presence of a
new age, as different from the middle ages as from the ages of Greece and
Rome, was fully realised. It was then that the triple division of ancient,
medieval, and modern was first applied to the history of western
civilisation. Whatever objections may be urged against this division,
which has now become almost a category of thought, it marks a most
significant advance in man's view of his own past. He has become conscious
of the immense changes in civilisation which have come about slowly in the
course of time, and history confronts him with a new aspect. He has to
explain how those changes have been produced, how the transformations were
effected. The appearance of this problem was almost simultaneous with the
rise of rationalism, and the great historians and thinkers of the
eighteenth century, such as Montesquieu, Voltaire, Gibbon, attempted to
explain the movement of civilisation by purely natural causes. These
brilliant writers prepared the way for the genetic history of the following
century. But in the spirit of the Aufklarung, that eighteenth-century
Enlightenment to which they belonged, they were concerned to judge all
phenomena before the tribunal of reason; and the apotheosis of "reason"
tended to foster a certain superior a priori attitude, which was not
favourable to objective treatment and was incompatible with a "historical
sense." Moreover the traditions of pragmatical historiography had by no
means disappeared.

3. In the first quarter of the nineteenth century the meaning of genetic
history was fully realised. "Genetic" perhaps is as good a word as can be
found for the conception which in this century was applied to so many
branches of knowledge in the spheres both of nature and of mind. It does
not commit us to the doctrine proper of evolution, nor yet to any
teleological hypothesis such as is implied in "progress." For history it
meant that the present condition of the human race is simply and strictly
the result of a causal series (or set of causal series)--a continuous
succession of changes, where each state arises causally out of the
preceding; and that the business of historians is to trace this genetic
process, to explain each change, and ultimately to grasp the complete
development of the life of humanity. Three influential writers, who
appeared at this stage and helped to initiate a new period of research, may
specially be mentioned. Ranke in 1824 definitely repudiated the
pragmatical view which ascribes to history the duties of an instructress,
and with no less decision renounced the function, assumed by the historians
of the Aufklarung, to judge the past; it was his business, he said, merely
to show how things really happened. Niebuhr was already working in the
same spirit and did more than any other writer to establish the principle
that historical transactions must be related to the ideas and conditions of
their age. Savigny about the same time founded the "historical school" of
law. He sought to show that law was not the creation of an enlightened
will, but grew out of custom and was developed by a series of adaptations
and rejections, thus applying the conception of evolution. He helped to
diffuse the notion that all the institutions of a society or a notion are
as closely interconnected as the parts of a living organism.

4. The conception of the history of man as a causal development meant the
elevation of historical inquiry to the dignity of a science. Just as the
study of bees cannot become scientific so long as the student's interest in
them is only to procure honey or to derive moral lessons from the labours
of "the little busy bee," so the history of human societies cannot become
the object of pure scientific investigation so long as man estimates its
value in pragmatical scales. Nor can it become a science until it is
conceived as lying entirely within a sphere in which the law of cause and
effect has unreserved and unrestricted dominion. On the other hand, once
history is envisaged as a causal process, which contains within itself the
explanation of the development of man from his primitive state to the point
which he has reached, such a process necessarily becomes the object of
scientific investigation and the interest in it is scientific curiosity.

At the same time, the instruments were sharpened and refined. Here Wolf, a
philologist with historical instinct, was a pioneer. His "Prolegomena" to
Homer (1795) announced new modes of attack. Historical investigation was
soon transformed by the elaboration of new methods.

5. "Progress" involves a judgment of value, which is not involved in the
conception of history as a genetic process. It is also an idea distinct
from that of evolution. Nevertheless it is closely related to the ideas
which revolutionised history at the beginning of the last century; it swam
into men's ken simultaneously; and it helped effectively to establish the
notion of history as a continuous process and to emphasise the significance
of time. Passing over earlier anticipations, I may point to a "Discours"
of Turgot (1750), where history is presented as a process in which "the
total mass of the human race" "marches continually though sometimes slowly
to an ever increasing perfection." That is a clear statement of the
conception which Turgot's friend Condorcet elaborated in the famous work,
published in 1795, "Esquisse d'un tableau historique des progres de
l'esprit humain". This work first treated with explicit fulness the idea
to which a leading role was to fall in the ideology of the nineteenth
century. Condorcet's book reflects the triumphs of the Tiers etat, whose
growing importance had also inspired Turgot; it was the political changes
in the eighteenth century which led to the doctrine, emphatically
formulated by Condorcet, that the masses are the most important element in
the historical process. I dwell on this because, though Condorcet had no
idea of evolution, the pre-dominant importance of the masses was the
assumption which made it possible to apply evolutional principles to
history. And it enabled Condorcet himself to maintain that the history of
civilisation, a progress still far from being complete, was a development
conditioned by general laws.

6. The assimilation of society to an organism, which was a governing
notion in the school of Savigny, and the conception of progress, combined
to produce the idea of an organic development, in which the historian has
to determine the central principle or leading character. This is
illustrated by the apotheosis of democracy in Tocqueville's "Democratie en
Amerique", where the theory is maintained that "the gradual and progressive
development of equality is at once the past and the future of the history
of men." The same two principles are combined in the doctrine of Spencer
(who held that society is an organism, though he also contemplated its
being what he calls a "super-organic aggregate") (A society presents
suggestive analogies with an organism, but it certainly is not an organism,
and sociologists who draw inferences from the assumption of its organic
nature must fall into error. A vital organism and a society are radically
distinguished by the fact that the individual components of the former,
namely the cells, are morphologically as well as functionally
differentiated, whereas the individuals which compose a society are
morphologically homogeneous and only functionally differentiated. The
resemblances and the differences are worked out in E. de Majewski's
striking book "La Science de la Civilisation", Paris, 1908.), that social
evolution is a progressive change from militarism to industrialism.

7. the idea of development assumed another form in the speculations of
German idealism. Hegel conceived the successive periods of history as
corresponding to the ascending phases or ideas in the self-evolution of his
Absolute Being. His "Lectures on the Philosophy of History" were published
in 1837 after his death. His philosophy had a considerable effect, direct
and indirect, on the treatment of history by historians, and although he
was superficial and unscientific himself in dealing with historical
phenomena, he contributed much towards making the idea of historical
development familiar. Ranke was influenced, if not by Hegel himself, at
least by the Idealistic philosophies of which Hegel's was the greatest. He
was inclined to conceive the stages in the process of history as marked by
incarnations, as it were, of ideas, and sometimes speaks as if the ideas
were independent forces, with hands and feet. But while Hegel determined
his ideas by a priori logic, Ranke obtained his by induction--by a strict
investigation of the phenomena; so that he was scientific in his method and
work, and was influenced by Hegelian prepossessions only in the kind of
significance which he was disposed to ascribe to his results. It is to be
noted that the theory of Hegel implied a judgment of value; the movement
was a progress towards perfection.

8. In France, Comte approached the subject from a different side, and
exercised, outside Germany, a far wider influence than Hegel. The 4th
volume of his "Cours de philosophie positive", which appeared in 1839,
created sociology and treated history as a part of this new science, namely
as "social dynamics." Comte sought the key for unfolding historical
development, in what he called the social-psychological point of view, and
he worked out the two ideas which had been enunciated by Condorcet: that
the historian's attention should be directed not, as hitherto, principally
to eminent individuals, but to the collective behaviour of the masses, as
being the most important element in the process; and that, as in nature, so
in history, there are general laws, necessary and constant, which condition
the development. The two points are intimately connected, for it is only
when the masses are moved into the foreground that regularity, uniformity,
and law can be conceived as applicable. To determine the social-
psychological laws which have controlled the development is, according to
Comte, the task of sociologists and historians.

9. The hypothesis of general laws operative in history was carried further
in a book which appeared in England twenty years later and exercised an
influence in Europe far beyond its intrinsic merit, Buckle's "History of
Civilisation in England" (1857-61). Buckle owed much to Comte, and
followed him, or rather outdid him, in regarding intellect as the most
important factor conditioning the upward development of man, so that
progress, according to him, consisted in the victory of the intellectual
over the moral laws.

10. The tendency of Comte and Buckle to assimilate history to the sciences
of nature by reducing it to general "laws," derived stimulus and
plausibility from the vista offered by the study of statistics, in which
the Belgian Quetelet, whose book "Sur l'homme" appeared in 1835, discerned
endless possibilities. The astonishing uniformities which statistical
inquiry disclosed led to the belief that it was only a question of
collecting a sufficient amount of statistical material, to enable us to
predict how a given social group will act in a particular case. Bourdeau,
a disciple of this school, looks forward to the time when historical
science will become entirely quantitative. The actions of prominent
individuals, which are generally considered to have altered or determined
the course of things, are obviously not amenable to statistical computation
or explicable by general laws. Thinkers like Buckle sought to minimise
their importance or explain them away.

11. These indications may suffice to show that the new efforts to
interpret history which marked the first half of the nineteenth century
were governed by conceptions closely related to those which were current in
the field of natural science and which resulted in the doctrine of
evolution. The genetic principle, progressive development, general laws,
the significance of time, the conception of society as an organic
aggregate, the metaphysical theory of history as the self-evolution of
spirit,--all these ideas show that historical inquiry had been advancing
independently on somewhat parallel lines to the sciences of nature. It was
necessary to bring this out in order to appreciate the influence of

12. In the course of the dozen years which elapsed between the appearances
of "The Origin of Species" (observe that the first volume of Buckle's work
was published just two years before) and of "The Descent of Man" (1871),
the hypothesis of Lamarck that man is the co-descendant with other species
of some lower extinct form was admitted to have been raised to the rank of
an established fact by most thinkers whose brains were not working under
the constraint of theological authority.

One important effect of the discovery of this fact (I am not speaking now
of the Darwinian explanation) was to assign to history a definite place in
the coordinated whole of knowledge, and relate it more closely to other
sciences. It had indeed a defined logical place in systems such as Hegel's
and Comte's; but Darwinism certified its standing convincingly and without
more ado. The prevailing doctrine that man was created ex abrupto had
placed history in an isolated position, disconnected with the sciences of
nature. Anthropology, which deals with the animal anthropos, now comes
into line with zoology, and brings it into relation with history. (It is
to be observed that history is (not only different in scope but) not
coextensive with anthropology IN TIME. For it deals only with the
development of man in societies, whereas anthropology includes in its
definition the proto-anthropic period when anthropos was still non-social,
whether he lived in herds like the chimpanzee, or alone like the male
ourang-outang. (It has been well shown by Majewski that congregations--
herds, flocks, packs, etc.--of animals are not SOCIETIES; the
characteristic of a society is differentiation of function. Bee hives, ant
hills, may be called quasi-societies; but in their case the classes which
perform distinct functions are morphologically different.) Man's condition
at the present day is the result of a series of transformations, going back
to the most primitive phase of society, which is the ideal (unattainable)
beginning of history. But that beginning had emerged without any breach of
continuity from a development which carries us back to a quadrimane
ancestor, still further back (according to Darwin's conjecture) to a marine
animal of the ascidian type, and then through remoter periods to the lowest
form of organism. It is essential in this theory that though links have
been lost there was no break in the gradual development; and this
conception of a continuous progress in the evolution of life, resulting in
the appearance of uncivilised Anthropos, helped to reinforce, and increase
a belief in, the conception of the history of civilised Anthropos as itself
also a continuous progressive development.

13. Thus the diffusion of the Darwinian theory of the origin of man, by
emphasising the idea of continuity and breaking down the barriers between
the human and animal kingdoms, has had an important effect in establishing
the position of history among the sciences which deal with telluric
development. The perspective of history is merged in a larger perspective
of development. As one of the objects of biology is to find the exact
steps in the genealogy of man from the lowest organic form, so the scope of
history is to determine the stages in the unique causal series from the
most rudimentary to the present state of human civilisation.

It is to be observed that the interest in historical research implied by
this conception need not be that of Comte. In the Positive Philosophy
history is part of sociology; the interest in it is to discover the
sociological laws. In the view of which I have just spoken, history is
permitted to be an end in itself; the reconstruction of the genetic process
is an independent interest. For the purpose of the reconstruction,
sociology, as well as physical geography, biology, psychology, is
necessary; the sociologist and the historian play into each other's hands;
but the object of the former is to establish generalisations; the aim of
the latter is to trace in detail a singular causal sequence.

14. The success of the evolutional theory helped to discredit the
assumption or at least the invocation of transcendent causes.
Philosophically of course it is compatible with theism, but historians have
for the most part desisted from invoking the naive conception of a "god in
history" to explain historical movements. A historian may be a theist;
but, so far as his work is concerned, this particular belief is otiose.
Otherwise indeed (as was remarked above) history could not be a science;
for with a deus ex machina who can be brought on the stage to solve
difficulties scientific treatment is a farce. The transcendent element had
appeared in a more subtle form through the influence of German philosophy.
I noticed how Ranke is prone to refer to ideas as if they were transcendent
existences manifesting themselves in the successive movements of history.
It is intelligible to speak of certain ideas as controlling, in a given
period,--for instance, the idea of nationality; but from the scientific
point of view, such ideas have no existence outside the minds of
individuals and are purely psychical forces; and a historical "idea," if it
does not exist in this form, is merely a way of expressing a synthesis of
the historian himself.

15. From the more general influence of Darwinism on the place of history
in the system of human knowledge, we may turn to the influence of the
principles and methods by which Darwin explained development. It had been
recognised even by ancient writers (such as Aristotle and Polybius) that
physical circumstances (geography, climate) were factors conditioning the
character and history of a race or society. In the sixteenth century Bodin
emphasised these factors, and many subsequent writers took them into
account. The investigations of Darwin, which brought them into the
foreground, naturally promoted attempts to discover in them the chief key
to the growth of civilisation. Comte had expressly denounced the notion
that the biological methods of Lamarck could be applied to social man.
Buckle had taken account of natural influences, but had relegated them to a
secondary plane, compared with psychological factors. But the Darwinian
theory made it tempting to explain the development of civilisation in terms
of "adaptation to environment," "struggle for existence," "natural
selection," "survival of the fittest," etc. (Recently O. Seeck has applied
these principles to the decline of Graeco-Roman civilisation in his
"Untergang der antiken Welt", 2 volumes, Berlin, 1895, 1901.)

The operation of these principles cannot be denied. Man is still an
animal, subject to zoological as well as mechanical laws. The dark
influence of heredity continues to be effective; and psychical development
had begun in lower organic forms,--perhaps with life itself. The organic
and the social struggles for existence are manifestations of the same
principle. Environment and climatic influence must be called in to explain
not only the differentiation of the great racial sections of humanity, but
also the varieties within these sub-species and, it may be, the
assimilation of distinct varieties. Ritter's "Anthropogeography" has
opened a useful line of research. But on the other hand, it is urged that,
in explaining the course of history, these principles do not take us very
far, and that it is chiefly for the primitive ultra-prehistoric period that
they can account for human development. It may be said that, so far as
concerns the actions and movements of men which are the subject of recorded
history, physical environment has ceased to act mechanically, and in order
to affect their actions must affect their wills first; and that this
psychical character of the causal relations substantially alters the
problem. The development of human societies, it may be argued, derives a
completely new character from the dominance of the conscious psychical
element, creating as it does new conditions (inventions, social
institutions, etc.) which limit and counteract the operation of natural
selection, and control and modify the influence of physical environment.
Most thinkers agree now that the chief clews to the growth of civilisation
must be sought in the psychological sphere. Imitation, for instance, is a
principle which is probably more significant for the explanation of human
development than natural selection. Darwin himself was conscious that his
principles had only a very restricted application in this sphere, as is
evident from his cautious and tentative remarks in the 5th chapter of his
"Descent of Man". He applied natural selection to the growth of the
intellectual faculties and of the fundamental social instincts, and also to
the differentiation of the great races or "sub-species" (Caucasian,
African, etc.) which differ in anthropological character. (Darwinian
formulae may be suggestive by way of analogy. For instance, it is
characteristic of social advance that a multitude of inventions, schemes
and plans are framed which are never carried out, similar to, or designed
for the same end as, an invention or plan which is actually adopted because
it has chanced to suit better the particular conditions of the hour (just
as the works accomplished by an individual statesman, artist or savant are
usually only a residue of the numerous projects conceived by his brain).
This process in which so much abortive production occurs is analogous to
elimination by natural selection.)

16. But if it is admitted that the governing factors which concern the
student of social development are of the psychical order, the preliminary
success of natural science in explaining organic evolution by general
principles encouraged sociologists to hope that social evolution could be
explained on general principles also. The idea of Condorcet, Buckle, and
others, that history could be assimilated to the natural sciences was
powerfully reinforced, and the notion that the actual historical process,
and every social movement involved in it, can be accounted for by
sociological generalisations, so-called "laws," is still entertained by
many, in one form or another. Dissentients from this view do not deny that
the generalisations at which the sociologist arrives by the comparative
method, by the analysis of social factors, and by psychological deduction
may be an aid to the historian; but they deny that such uniformities are
laws or contain an explanation of the phenomena. They can point to the
element of chance coincidence. This element must have played a part in the
events of organic evolution, but it has probably in a larger measure helped
to determine events in social evolution. The collision of two unconnected
sequences may be fraught with great results. The sudden death of a leader
or a marriage without issue, to take simple cases, has again and again led
to permanent political consequences. More emphasis is laid on the decisive
actions of individuals, which cannot be reduced under generalisations and
which deflect the course of events. If the significance of the individual
will had been exaggerated to the neglect of the collective activity of the
social aggregate before Condorcet, his doctrine tended to eliminate as
unimportant the roles of prominent men, and by means of this elimination it
was possible to found sociology. But it may be urged that it is patent on
the face of history that its course has constantly been shaped and modified
by the wills of individuals (We can ignore here the metaphysical question
of freewill and determinism. For the character of the individual's brain
depends in any case on ante-natal accidents and coincidences, and so it may
be said that the role of individuals ultimately depends on chance,--the
accidental coincidence of independent sequences.), which are by no means
always the expression of the collective will; and that the appearance of
such personalities at the given moments is not a necessary outcome of the
conditions and cannot be deduced. Nor is there any proof that, if such and
such an individual had not been born, some one else would have arisen to do
what he did. In some cases there is no reason to think that what happened
need ever have come to pass. In other cases, it seems evident that the
actual change was inevitable, but in default of the man who initiated and
guided it, it might have been postponed, and, postponed or not, might have
borne a different cachet. I may illustrate by an instance which has just
come under my notice. Modern painting was founded by Giotto, and the
Italian expedition of Charles VIII, near the close of the sixteenth
century, introduced into France the fashion of imitating Italian painters.
But for Giotto and Charles VIII, French painting might have been very
different. It may be said that "if Giotto had not appeared, some other
great initiator would have played a role analogous to his, and that without
Charles VIII there would have been the commerce with Italy, which in the
long run would have sufficed to place France in relation with Italian
artists. But the equivalent of Giotto might have been deferred for a
century and probably would have been different; and commercial relations
would have required ages to produce the rayonnement imitatif of Italian art
in France, which the expedition of the royal adventurer provoked in a few
years." (I have taken this example from G. Tarde's "La logique sociale" 2
(page 403), Paris, 1904, where it is used for quite a different purpose.)
Instances furnished by political history are simply endless. Can we
conjecture how events would have moved if the son of Philip of Macedon had
been an incompetent? The aggressive action of Prussia which astonished
Europe in 1740 determined the subsequent history of Germany; but that
action was anything but inevitable; it depended entirely on the personality
of Frederick the Great.

Hence it may be argued that the action of individual wills is a determining
and disturbing factor, too significant and effective to allow history to be
grasped by sociological formulae. The types and general forms of
development which the sociologist attempts to disengage can only assist the
historian in understanding the actual course of events. It is in the
special domains of economic history and Culturgeschichte which have come to
the front in modern times that generalisation is most fruitful, but even in
these it may be contended that it furnishes only partial explanations.

17. The truth is that Darwinism itself offers the best illustration of the
insufficiency of general laws to account for historical development. The
part played by coincidence, and the part played by individuals--limited by,
and related to, general social conditions--render it impossible to deduce
the course of the past history of man or to predict the future. But it is
just the same with organic development. Darwin (or any other zoologist)
could not deduce the actual course of evolution from general principles.
Given an organism and its environment, he could not show that it must
evolve into a more complex organism of a definite pre-determined type;
knowing what it has evolved into, he could attempt to discover and assign
the determining causes. General principles do not account for a particular
sequence; they embody necessary conditions; but there is a chapter of
accidents too. It is the same in the case of history.

18. Among the evolutional attempts to subsume the course of history under
general syntheses, perhaps the most important is that of Lamprecht, whose
"kulturhistorische Methode," which he has deduced from and applied to
German history, exhibits the (indirect) influence of the Comtist school.
It is based upon psychology, which, in his view, holds among the sciences
of mind (Geisteswissenschaften) the same place (that of a
Grundwissenschaft) which mechanics holds among the sciences of nature.
History, by the same comparison, corresponds to biology, and, according to
him, it can only become scientific if it is reduced to general concepts
(Begriffe). Historical movements and events are of a psychical character,
and Lamprecht conceives a given phase of civilisation as "a collective
psychical condition (seelischer Gesamtzustand)" controlling the period, "a
diapason which penetrates all psychical phenomena and thereby all
historical events of the time." ("Die kulturhistorische Methode", Berlin,
1900, page 26.) He has worked out a series of such phases, "ages of
changing psychical diapason," in his "Deutsche Geschichte" with the aim of
showing that all the feelings and actions of each age can be explained by
the diapason; and has attempted to prove that these diapasons are exhibited
in other social developments, and are consequently not singular but
typical. He maintains further that these ages succeed each other in a
definite order; the principle being that the collective psychical
development begins with the homogeneity of all the individual members of a
society and, through heightened psychical activity, advances in the form of
a continually increasing differentiation of the individuals (this is akin
to the Spencerian formula). This process, evolving psychical freedom from
psychical constraint, exhibits a series of psychical phenomena which define
successive periods of civilisation. The process depends on two simple
principles, that no idea can disappear without leaving behind it an effect
or influence, and that all psychical life, whether in a person or a
society, means change, the acquisition of new mental contents. It follows
that the new have to come to terms with the old, and this leads to a
synthesis which determines the character of a new age. Hence the ages of
civilisation are defined as the "highest concepts for subsuming without
exception all psychical phenomena of the development of human societies,
that is, of all historical events." (Ibid. pages 28, 29.) Lamprecht
deduces the idea of a special historical science, which might be called
"historical ethnology," dealing with the ages of civilisation, and bearing
the same relation to (descriptive or narrative) history as ethnology to
ethnography. Such a science obviously corresponds to Comte's social
dynamics, and the comparative method, on which Comte laid so much emphasis,
is the principal instrument of Lamprecht.

19. I have dwelt on the fundamental ideas of Lamprecht, because they are
not yet widely known in England, and because his system is the ablest
product of the sociological school of historians. It carries the more
weight as its author himself is a historical specialist, and his historical
syntheses deserve the most careful consideration. But there is much in the
process of development which on such assumptions is not explained,
especially the initiative of individuals. Historical development does not
proceed in a right line, without the choice of diverging. Again and again,
several roads are open to it, of which it chooses one--why? On Lamprecht's
method, we may be able to assign the conditions which limit the psychical
activity of men at a particular stage of evolution, but within those limits
the individual has so many options, such a wide room for moving, that the
definition of those conditions, the "psychical diapasons," is only part of
the explanation of the particular development. The heel of Achilles in all
historical speculations of this class has been the role of the individual.

The increasing prominence of economic history has tended to encourage the
view that history can be explained in terms of general concepts or types.
Marx and his school based their theory of human development on the
conditions of production, by which, according to them, all social movements
and historical changes are entirely controlled. The leading part which
economic factors play in Lamprecht's system is significant, illustrating
the fact that economic changes admit most readily this kind of treatment,
because they have been less subject to direction or interference by
individual pioneers.

Perhaps it may be thought that the conception of SOCIAL ENVIRONMENT
(essentially psychical), on which Lamprecht's "psychical diapasons" depend,
is the most valuable and fertile conception that the historian owes to the
suggestion of the science of biology--the conception of all particular
historical actions and movements as (1) related to and conditioned by the
social environment, and (2) gradually bringing about a transformation of
that environment. But no given transformation can be proved to be
necessary (pre-determined). And types of development do not represent
laws; their meaning and value lie in the help they may give to the
historian, in investigating a certain period of civilisation, to enable him
to discover the interrelations among the diverse features which it
presents. They are, as some one has said, an instrument of heuretic

20. The men engaged in special historical researches--which have been
pursued unremittingly for a century past, according to scientific methods
of investigating evidence (initiated by Wolf, Niebuhr, Ranke)--have for the
most part worked on the assumptions of genetic history or at least followed
in the footsteps of those who fully grasped the genetic point of view. But
their aim has been to collect and sift evidence, and determine particular
facts; comparatively few have given serious thought to the lines of
research and the speculations which have been considered in this paper.
They have been reasonably shy of compromising their work by applying
theories which are still much debated and immature. But historiography
cannot permanently evade the questions raised by these theories. One may
venture to say that no historical change or transformation will be fully
understood until it is explained how social environment acted on the
individual components of the society (both immediately and by heredity),
and how the individuals reacted upon their environment. The problem is
psychical, but it is analogous to the main problem of the biologist.

In ordinary speech a system of any sort is said to be stable when it cannot
be upset easily, but the meaning attached to the word is usually somewhat
vague. It is hardly surprising that this should be the case, when it is
only within the last thirty years, and principally through the
investigations of M. Poincare, that the conception of stability has, even
for physicists, assumed a definiteness and clearness in which it was
previously lacking. The laws which govern stability hold good in regions
of the greatest diversity; they apply to the motion of planets round the
sun, to the internal arrangement of those minute corpuscles of which each
chemical atom is constructed, and to the forms of celestial bodies. In the
present essay I shall attempt to consider the laws of stability as relating
to the last case, and shall discuss the succession of shapes which may be
assumed by celestial bodies in the course of their evolution. I believe
further that homologous conceptions are applicable in the consideration of
the transmutations of the various forms of animal and of vegetable life and
in other regions of thought. Even if some of my readers should think that
what I shall say on this head is fanciful, yet at least the exposition will
serve to illustrate the meaning to be attached to the laws of stability in
the physical universe.

I propose, therefore, to begin this essay by a sketch of the principles of
stability as they are now formulated by physicists.


If a slight impulse be imparted to a system in equilibrium one of two
consequences must ensue; either small oscillations of the system will be
started, or the disturbance will increase without limit and the arrangement
of the system will be completely changed. Thus a stick may be in
equilibrium either when it hangs from a peg or when it is balanced on its
point. If in the first case the stick is touched it will swing to and fro,
but in the second case it will topple over. The first position is a stable
one, the second is unstable. But this case is too simple to illustrate all
that is implied by stability, and we must consider cases of stable and of
unstable motion. Imagine a satellite and its planet, and consider each of
them to be of indefinitely small size, in fact particles; then the
satellite revolves round its planet in an ellipse. A small disturbance
imparted to the satellite will only change the ellipse to a small amount,
and so the motion is said to be stable. If, on the other hand, the
disturbance were to make the satellite depart from its initial elliptic
orbit in ever widening circuits, the motion would be unstable. This case
affords an example of stable motion, but I have adduced it principally with
the object of illustrating another point not immediately connected with
stability, but important to a proper comprehension of the theory of

The motion of a satellite about its planet is one of revolution or
rotation. When the satellite moves in an ellipse of any given degree of
eccentricity, there is a certain amount of rotation in the system,
technically called rotational momentum, and it is always the same at every
part of the orbit. (Moment of momentum or rotational momentum is measured
by the momentum of the satellite multiplied by the perpendicular from the
planet on to the direction of the path of the satellite at any instant.)

Now if we consider all the possible elliptic orbits of a satellite about
its planet which have the same amount of "rotational momentum," we find
that the major axis of the ellipse described will be different according to
the amount of flattening (or the eccentricity) of the ellipse described. A
figure titled "A 'family' of elliptic orbits with constant rotational
momentum" (Fig. 1) illustrates for a given planet and satellite all such
orbits with constant rotational momentum, and with all the major axes in
the same direction. It will be observed that there is a continuous
transformation from one orbit to the next, and that the whole forms a
consecutive group, called by mathematicians "a family" of orbits. In this
case the rotational momentum is constant and the position of any orbit in
the family is determined by the length of the major axis of the ellipse;
the classification is according to the major axis, but it might have been
made according to anything else which would cause the orbit to be exactly

I shall come later to the classification of all possible forms of ideal
liquid stars, which have the same amount of rotational momentum, and the
classification will then be made according to their densities, but the idea
of orderly arrangement in a "family" is just the same.

We thus arrive at the conception of a definite type of motion, with a
constant amount of rotational momentum, and a classification of all members
of the family, formed by all possible motions of that type, according to
the value of some measurable quantity (this will hereafter be density)
which determines the motion exactly. In the particular case of the
elliptic motion used for illustration the motion was stable, but other
cases of motion might be adduced in which the motion would be unstable, and
it would be found that classification in a family and specification by some
measurable quantity would be equally applicable.

A complex mechanical system may be capable of motion in several distinct
modes or types, and the motions corresponding to each such type may be
arranged as before in families. For the sake of simplicity I will suppose
that only two types are possible, so that there will only be two families;
and the rotational momentum is to be constant. The two types of motion
will have certain features in common which we denote in a sort of shorthand
by the letter A. Similarly the two types may be described as A + a and A +
b, so that a and b denote the specific differences which discriminate the
families from one another. Now following in imagination the family of the
type A + a, let us begin with the case where the specific difference a is
well marked. As we cast our eyes along the series forming the family, we
find the difference a becoming less conspicuous. It gradually dwindles
until it disappears; beyond this point it either becomes reversed, or else
the type has ceased to be a possible one. In our shorthand we have started
with A + a, and have watched the characteristic a dwindling to zero. When
it vanishes we have reached a type which may be specified as A; beyond this
point the type would be A - a or would be impossible.

Following the A + b type in the same way, b is at first well marked, it
dwindles to zero, and finally may become negative. Hence in shorthand this
second family may be described as A + b,...A,...A - b.

In each family there is one single member which is indistinguishable from a
member of the other family; it is called by Poincare a form of bifurcation.
It is this conception of a form of bifurcation which forms the important
consideration in problems dealing with the forms of liquid or gaseous
bodies in rotation.

But to return to the general question,--thus far the stability of these
families has not been considered, and it is the stability which renders
this way of looking at the matter so valuable. It may be proved that if
before the point of bifurcation the type A + a was stable, then A + b must
have been unstable. Further as a and b each diminish A + a becomes less
pronouncedly stable, and A + b less unstable. On reaching the point of
bifurcation A + a has just ceased to be stable, or what amounts to the same
thing is just becoming unstable, and the converse is true of the A + b
family. After passing the point of bifurcation A + a has become definitely
unstable and A + b has become stable. Hence the point of bifurcation is
also a point of "exchange of stabilities between the two types." (In order
not to complicate unnecessarily this explanation of a general principle I
have not stated fully all the cases that may occur. Thus: firstly, after
bifurcation A + a may be an impossible type and A + a will then stop at
this point; or secondly, A + b may have been an impossible type before
bifurcation, and will only begin to be a real one after it; or thirdly,
both A + a and A + b may be impossible after the point of bifurcation, in
which case they coalesce and disappear. This last case shows that types
arise and disappear in pairs, and that on appearance or before
disappearance one must be stable and the other unstable.)

In nature it is of course only the stable types of motion which can persist
for more than a short time. Thus the task of the physical evolutionist is
to determine the forms of bifurcation, at which he must, as it were, change
carriages in the evolutionary journey so as always to follow the stable
route. He must besides be able to indicate some natural process which
shall correspond in effect to the ideal arrangement of the several types of
motion in families with gradually changing specific differences. Although,
as we shall see hereafter, it may frequently or even generally be
impossible to specify with exactness the forms of bifurcation in the
process of evolution, yet the conception is one of fundamental importance.

The ideas involved in this sketch are no doubt somewhat recondite, but I
hope to render them clearer to the non-mathematical reader by homologous
considerations in other fields of thought (I considered this subject in my
Presidential address to the British Association in 1905, "Report of the
75th Meeting of the British Assoc." (S. Africa, 1905), London, 1906, page
3. Some reviewers treated my speculations as fanciful, but as I believe
that this was due generally to misapprehension, and as I hold that
homologous considerations as to stability and instability are really
applicable to evolution of all sorts, I have thought it well to return to
the subject in the present paper.), and I shall pass on thence to
illustrations which will teach us something of the evolution of stellar

States or governments are organised schemes of action amongst groups of
men, and they belong to various types to which generic names, such as
autocracy, aristocracy or democracy, are somewhat loosely applied. A
definite type of government corresponds to one of our types of motion, and
while retaining its type it undergoes a slow change as the civilisation and
character of the people change, and as the relationship of the nation to
other nations changes. In the language used before, the government belongs
to a family, and as time advances we proceed through the successive members
of the family. A government possesses a certain degree of stability--
hardly measurable in numbers however--to resist disintegrating influences
such as may arise from wars, famines, and internal dissensions. This
stability gradually rises to a maximum and gradually declines. The degree
of stability at any epoch will depend on the fitness of some leading
feature of the government to suit the slowly altering circumstances, and
that feature corresponds to the characteristic denoted by a in the physical
problem. A time at length arrives when the stability vanishes, and the
slightest shock will overturn the government. At this stage we have
reached the crisis of a point of bifurcation, and there will then be some
circumstance, apparently quite insignificant and almost unnoticed, which is
such as to prevent the occurrence of anarchy. This circumstance or
condition is what we typified as b. Insignificant although it may seem, it
has started the government on a new career of stability by imparting to it
a new type. It grows in importance, the form of government becomes
obviously different, and its stability increases. Then in its turn this
newly acquired stability declines, and we pass on to a new crisis or
revolution. There is thus a series of "points of bifurcation" in history
at which the continuity of political history is maintained by means of
changes in the type of government. These ideas seem, to me at least, to
give a true account of the history of states, and I contend that it is no
mere fanciful analogy but a true homology, when in both realms of thought--
the physical and the political--we perceive the existence of forms of
bifurcation and of exchanges of stability.

Further than this, I would ask whether the same train of ideas does not
also apply to the evolution of animals? A species is well adapted to its
environment when the individual can withstand the shocks of famine or the
attacks and competition of other animals; it then possesses a high degree
of stability. Most of the casual variations of individuals are
indifferent, for they do not tell much either for or against success in
life; they are small oscillations which leave the type unchanged. As
circumstances change, the stability of the species may gradually dwindle
through the insufficiency of some definite quality, on which in earlier
times no such insistent demands were made. The individual animals will
then tend to fail in the struggle for life, the numbers will dwindle and
extinction may ensue. But it may be that some new variation, at first of
insignificant importance, may just serve to turn the scale. A new type may
be formed in which the variation in question is preserved and augmented;
its stability may increase and in time a new species may be produced.

At the risk of condemnation as a wanderer beyond my province into the
region of biological evolution, I would say that this view accords with
what I understand to be the views of some naturalists, who recognise the
existence of critical periods in biological history at which extinction
occurs or which form the starting-point for the formation of new species.
Ought we not then to expect that long periods will elapse during which a
type of animal will remain almost constant, followed by other periods,
enormously long no doubt as measured in the life of man, of acute struggle
for existence when the type will change more rapidly? This at least is the
view suggested by the theory of stability in the physical universe. (I
make no claim to extensive reading on this subject, but refer the reader
for example to a paper by Professor A.A.W. Hubrecht on "De Vries's theory
of Mutations", "Popular Science Monthly", July 1904, especially to page

And now I propose to apply these ideas of stability to the theory of
stellar evolution, and finally to illustrate them by certain recent
observations of a very remarkable character.

Stars and planets are formed of materials which yield to the enormous
forces called into play by gravity and rotation. This is obviously true if
they are gaseous or fluid, and even solid matter becomes plastic under
sufficiently great stresses. Nothing approaching a complete study of the
equilibrium of a heterogeneous star has yet been found possible, and we are
driven to consider only bodies of simpler construction. I shall begin
therefore by explaining what is known about the shapes which may be assumed
by a mass of incompressible liquid of uniform density under the influences
of gravity and of rotation. Such a liquid mass may be regarded as an ideal
star, which resembles a real star in the fact that it is formed of
gravitating and rotating matter, and because its shape results from the
forces to which it is subject. It is unlike a star in that it possesses
the attributes of incompressibility and of uniform density. The difference
between the real and the ideal is doubtless great, yet the similarity is
great enough to allow us to extend many of the conclusions as to ideal
liquid stars to the conditions which must hold good in reality. Thus with
the object of obtaining some insight into actuality, it is justifiable to
discuss an avowedly ideal problem at some length.

The attraction of gravity alone tends to make a mass of liquid assume the
shape of a sphere, and the effects of rotation, summarised under the name
