CHAPTER XIV

ANIMAL DISPLAY

In a treatment of the relation between art and sexual life the facts

must necessarily be classified under two different headings, namely,

the influence of artistic activity upon sexual selection and the

importance of erotic motives in works of art. These two points of view

have indeed often been confounded with each other. But it will soon

appear from the following how indispensable it is to maintain the

distinction between them.

In modern literature there has scarcely appeared any treatise of the

same importance, not only for the theory of art, but also for æsthetic

proper, as the chapters on sexual selection in _The Descent of Man_. As

is well known, Darwin supposes a necessary connection between beauty

and art. He takes it for granted that music, poetry, drama, and the

rest chiefly aim at pleasing. When he sees that activities and forms,

which at least technically correspond to the various kinds of art,

are to be met with not only among the lower tribes of man, but even

among some of the higher animals, he therefore explains these forms

and activities as emanating from a conscious or unconscious endeavour

to please through beauty. And for this endeavour he finds a reason in

the necessity of gaining preference in the favour of the female. By

endowing the female with æsthetic attention and æsthetic judgment[262]

he has been able not only to explain the appearance of art amongst

savages and animals, but also to account for the importance of beauty

in life.

In the foregoing arguments we have already with sufficient clearness

pronounced our dissent from Darwin’s primary supposition. In the

chapter upon the art-impulse we have tried to show that this tendency

in its essence is something quite different from the tendency to

“attract by pleasing.” But with all this theoretical argumentation

it has of course not been proved that the endeavour of the males

to win the favour of the females by singing, dancing, and other

similar performances has exercised no influence on the _history_ of

art. However little these activities may have to do with real art,

they might, however, have afforded a raw material to be used by the

art-impulse proper for its own purposes. In this connection it is

necessary, therefore, to discuss the question, To what extent has

æsthetic choice, exercised by either of the sexes in selecting a mate,

favoured the development of artistic activities in the other sex?

The æsthetic theory of Darwin has its chief interest in the fact that

it can be applied to the activities of animals as well as to those of

men. Darwin himself has chosen the majority of his examples from bird

life, and his critics have generally restricted the discussion to the

zoological application of his thesis. As the data of animal psychology

are less complicated than the corresponding facts in the mental life of

man, it is in every respect advantageous to begin with this supposed

animal art. When the illustrations are chosen from bird life the

argumentation can, moreover, be handled with a freedom which would be

impossible in discussing the delicate questions of human erotics and

sexual life.

The theory of an appeal to some primordial æsthetic appreciation

in the hen birds is one which, however well it may account for the

beautiful plumage of some species and for the melodious singing of

some others, necessarily must arouse objections from the point of view

of comparative psychology. Æsthetic judgment presupposes a certain

development not only of intellectual qualities, but also of moral

self-restraint. In other words, it might be said that attention to

beauty, whether manifested in forms or colours or sounds, always

is what Ribot calls an “attention volontaire.”[263] It is hard to

believe that the hen really has reached such a state of spiritual

freedom that, when looking at the finery and the antics of her rival

suitors, she could be able to bestow her attention upon the æsthetic

qualities in the display. One has only to work out into all its details

and consequences the idea of a bird who approves or disapproves the

performance, and who, after balancing the merits of the various

competitors, awards her prize to the one nearest her ideal of beauty,

in order to realise the improbability, not to say the absurdity, of

this avian connoisseurship. M. Espinas, who describes in detail the

dilemma of the anxiously hesitating arbiter, has added nothing to

the theory of æsthetic selection. But it may safely be said that his

illustration of the thesis acts as a caricature of it.[264]

The improbability of an æsthetic judgment is yet more palpable when

one considers the state of mind in which the hen is likely to be on the

occasion. It has indeed been contended with regard to some species—as,

for instance, the satyr bird—that the hen behaves with a perfect calm

and indifference during the display of the cock.[265] But it would be

undoubtedly too rash to form any general conclusion on the ground of

her outward show in some single instances. Amongst the wood-birds, on

the other hand, the hens are known to be so excited during the “Balz”

that they can easily be caught with the hands.[266]

To all these _a priori_ objections there may also be added the remark

of Geddes and Thomson, that if the females of insects and birds had

really called into existence all the detailed patterns on the dresses

of their respective males by the exercise of æsthetic selection, they

would possess more discrimination than is shown in their predilection

for any sort of gaudy-coloured objects, such as pebbles, slips of

paper, and rags.[267]

However great the psychological improbability of the supposed

æsthetic selection, there is still more reason to take exception to

it from an evolutionistic point of view. The female appreciation

for gaudy and gorgeous dresses must necessarily, as Darwin himself

remarks, in many cases give rise to a plumage, as a result of which

the males become encumbered in their movements and easily discovered

by their enemies.[268] Æsthetic judgment, which is in itself so

incomprehensible, would thus have been developed in a continuous

conflict with natural selection. This circumstance, more than anything

else, makes it indispensable to look for some more utilitarian cause of

the secondary sexual characters and activities than the hypothetical

necessity of satisfying a sense of beauty in the female sex.

By the theory that has been advanced by Wallace, and further

developed by Westermarck, the nuptial dresses of the males have

indeed been accounted for in a simple way.[269] Reference to the need

of recognisable marks for every different species can explain the

most prominent characteristics in male plumage without any appeal

to an æsthetic sense. This need, together with the equally great

indispensability of protective colouring, must necessarily give rise

to precisely such brilliant coloured spots on a monotonous or plain

surface as are so often found on the bodies of the northern birds. The

gaudier coloration of the tropical species, on the other hand, appears

as a result of their more brilliant surroundings. Even here protective

colouring often leaves to the colour of recognition only a narrow and

limited space, on which this has to develop itself with so much the

greater intensity. In this way one can find a reason not only for the

decorations, which are beautiful according to our standard, but also

for the inharmonious and glaring colour-combinations.

An adherent of sexual selection can, however, easily object that these

theories, however sound and sensible they may be, still leave the main

point in Darwin’s thesis quite unaffected. When trying to prove the

existence of an æsthetic judgment in birds, he did not lay so much

stress upon decorative plumage itself as upon the fact of its being

displayed in the presence of the hen. If secondary sexual characters

had their only purpose in facilitating recognition between individuals

of the same species, then these elaborate performances would be quite

superfluous. And this argument can of course be further strengthened by

reference to the musical and dancing entertainments given by the males.

Any theory which leaves these activities unexplained must therefore be

regarded as incomplete.

In Mr. Wallace’s _Darwinism_ due attention has indeed been paid

to pre-nuptial performances. But his explanation, viz. that the

dancing and singing, etc., are only the effect of an inner impulse to

movement and activity which accompanies sexual maturity,[270] can but

incompletely unriddle the problem. For the purpose of affording an

outflow to a surplus of vigour or of discharging a nervous tension,

activities of a far simpler character would have been sufficient. As,

however, amongst birds with gorgeous plumage every movement in the

display tends towards exhibiting their splendour with the greatest

possible _éclat_, an influence upon the hen cannot be argued away. It

is, as Darwin remarks, impossible to believe that the Argus pheasant,

for instance, should have developed precisely such a curious and

peculiar sort of dance, through which his beautiful dress is so

effectively shown forth, if this dance had been of no effect upon

its spectators.[271] This effect cannot, as has been shown above, be

considered an æsthetic one. It is also difficult to believe that the

hen, as it has been suggested, should appreciate the secondary sexual

characters as signs of greater or smaller vital force, and thus prefer

not the most beautiful, but the most vigorous and ardent mate.[272]

Whether it is founded on an æsthetic judgment or on an estimation

of the force displayed, her conscious choosing seems to be alike

improbable.

But if it is difficult to believe that the display of the males could

call forth an intellectual activity in the hen, such as that of

comparing and valuing the merits of the rival suitors,[273] one can

safely assume that it might influence her emotional and instinctive

life. And for the production of such an effect there is no need to

suppose any intervening æsthetic activity. Considering the close

parallelism which shows itself in the development of either sex, it

would only be natural if a colour and voice alteration in the cock,

which undeniably is dependent upon sexual ripening,[274] should

directly and almost physiologically imply a reaction in the sexual life

of the hen. The more energetically the male forces himself upon the

attention of the female by the conspicuous visual and acoustic signs of

his sex, the more powerful must necessarily be the emotional response

in her.

If secondary sexual characters are interpreted in this way, as signs,

by which the sex of the male is manifested in an unmistakable manner,

then one can easily understand the influence of a prolonged display.

When the cock is exhibiting his plumes or pouring forth his notes, and

thereby impressing upon his female listener the notion of his malehood,

he cannot but produce in her an enhanced inclination for pairing.[275]

She needs no æsthetic appreciation or intellectual judgment in order

to comprehend the simple text of all his utterances. With all her

instincts and impulses she can at once grasp the only thing she wants

to know—the thing that is brought home to her with a greater and

greater clearness during the continuation of his performance, namely,

that the passionate actor in front of her is a mature representative

of the other sex. And besides this, the secondary sexual characters

and activities tell another tale of no less importance. If the colours

and the tones of the cock, as Westermarck has shown, are of great

consequence for facilitating from a distance recognition between

members of the same species,[276] their biological significance is

perhaps yet greater when they, during the display before the hen,

accentuate the community of species. By virtue of her inherited

constitution, the instinctive life of the hen will be deeper stirred

the more the male is able to show that he “wears the feathers of her

tribe.”

It is evident that the effect upon the hen must be greater in

proportion as the sex marks and species marks of the male are more

clearly defined, and therefore easier to perceive. Not only as means

of recognition, but also as instruments for sexual incitement,

colour-patterns with lucent points must be more advantageous than any

other system of decoration. It is easily understood that a design like

that on the tails of pheasants and peacocks is eminently capable of

attracting the female attention to the displaying cock. But it would

be stretching the theory too far if the marvellous “balls on sockets”

were explained as nothing but conspicuous signals, the meaning of

which the hen is able to decipher by help of her inherited instincts.

The influence of the display is amongst these species undoubtedly

strengthened by an action which is quite independent of any sexual

associations. Besides accentuating the sex and kind of the cock, these

luminous spheres will, moreover, in virtue of their very smallness

and brilliancy, provoke a stimulation in the mind of the hen before

whom they are vibrated. To understand this effect, it is necessary

to investigate the more general question of animal appreciation of

brilliancy.

The powerful attraction exercised by lucent things can be sufficiently

proved by numerous instances from the life of insects and fishes as

well as of higher animals. It is needless to dwell upon the various

means by which man has availed himself of this disastrous predilection

in order to entice animals within reach of his weapons.[277] More

important in this connection is the mania for collecting lustrous

objects that has been noticed in the case of ravens, jays, magpies,

jackdaws, goldfinches, chiff-chaffs, sea-pies, etc.[278] It has

scarcely ever been suggested that the thievish jackdaw is prompted

by any _æsthetic_ liking for brilliant plate. But as it shows itself

amongst the atlas birds and the bower birds, this exaggeration of the

appropriative impulse has been regarded as an indication of artistic

inclination. It has been contended that these birds not only appreciate

shining and gorgeous objects, but even understand how to arrange them

according to a decorative plan.[279]

No one will deny that structures, such as, for instance, the gardens

of the atlas birds, which have been depicted by Beccari, are most

wonderful specimens of animal industry.[280] But it is undoubtedly

misleading to speak of them as artistic. As far as can be judged from

the descriptions—which are seldom complete—the arrangement of the

objects seems to be quite accidental. Darwin has indeed collected some

most eulogistic accounts of the decorative taste of the Australian

bower bird. But he has also, candidly enough, illustrated them with a

picture, on which an irregular heap of shells and bones is to be seen

in front of the bower. And the description he borrows from Mr. Strange

is yet more significant. To judge from this account, which is further

corroborated by the statement of Captain Stokes, the chief interest

of the birds seems to be not the arranging of their treasures, but

the playing with them. It has been noticed that the cock of the great

bower bird amuses himself by flying to and fro in the bower carrying

a shell in his bill, which he picks up on one side and carries to the

other.[281] On an anthropomorphic interpretation such a behaviour would

perhaps indicate a desire of trying some new decorative effect. But it

seems more natural to assume that brilliant objects, even after they

have been stored up in the nest, still exercise their irresistible

attraction, and thereby tempt the birds to repeated trifling with them.

If the supposed redecorations of the gardens be accounted for in this

manner, then there is no reason for considering the collecting impulse

in the Australian birds as anything more than a higher development of

the same tendency which shows itself in our common magpies and jackdaws.

By the Australian instances, however, the general predilection for

brilliant objects is brought into connection with the pairing dresses

of pheasants, peacocks, and humming birds. The small and brilliant

objects with which the bower birds play during their pairing season

remind us irresistibly of the “balls on sockets” and of the ocelli

designs of the colibri.[282] It is true that the pheasants carry on

their tail what the Australian birds keep in their bill. But apart

from this unimportant difference, the display seems to be the same in

both cases. In Mr. Strange’s letter it is said that the cock, when

performing the exalted antics that precede pairing, “runs to the bower,

picks up a gaudy feather or a spotted leaf, pours forth some peculiar

notes, and runs through the pavilion.” It is not quite clear from this

wording whether the objects really are exhibited _before_ the hen. But

one may safely assume that she in any case has paid some attention to

her consort’s performance. She has decidedly not, any more than the

pea-hen, received any sort of æsthetic impression from the display. But

the brilliancy has undoubtedly stimulated her, as it stimulates all

the other birds quoted in this connection, in a purely physiological

way. This action, on the other hand, is sufficiently explained by

recent researches on the physiological effects which the contemplation

of concentrated lustre produces on animal organisms. It is also well

known that objects with exactly the same qualities as the ocelli on the

peacock’s tail play an important part in hypnotic experiments. And the

primitive shamans as well as the modern cultivators of “crystal-gazing”

are acquainted with the peculiar effects of prolonged gazing on

glass-balls or the shining surface of water. More familiar still is

the fascinating influence exercised by that lustrous little globe, the

human eye.

In all these various examples the smallness of the object fetters the

attention, and thereby makes the mind a defenceless prey to the images,

feelings, and impulses which for the moment invade it. The lustre, on

the other hand, will, to use the language of M. Binet, strengthen the

intensity of these mental images.[283] There is no reason why these

effects, which presuppose no sort of intellectual activity, should not

take place in animals as well as in man. In the case of the peacock,

therefore, the idea “male” will imprint itself with greater and more

efficacy upon the mind of the hen when she is exposed on every side to

the twinkling eyes on the expanded tail of her mate.

Even in the very cases that have been regarded as the most

incontestable proofs of a taste for the beautiful, the influence on

the hen can thus be explained as one which directly, _i.e._ without

any æsthetic mediation, has served the interests of pairing. But it

may still be asked, Whence the need of strengthening and intensifying

the emotions in the female, which must already have been awakened by

the mere presence of the male? This objection, however, is easily met

by a reference to the psychological aspects of pairing. Throughout

the animal kingdom the males have to conquer a resistance from the

side of the females. This instinctive coyness, the importance of which

for the maintenance of the species is incalculable and self-evident,

constitutes by itself a sufficient cause for the supposed æsthetic

characters and activities of the males.[284] It has made it necessary

for them to have a stately carriage, which makes them bigger and more

pompous than ever, and to display their bodies in flying tricks, or

dances and antics,—in a word, to emphasise their sex as energetically

as possible by colours and tunes and movements. And this necessity has,

by means of a _natural_ selection, called forth a colouring which is

not only easily recognisable from a distance, but which also forces

itself on the senses when seen at close quarters.

The æsthetic judgment of the hen forms the pivot of the whole Darwinian

theory. When it has been eliminated, it is therefore quite superfluous

to controvert the assertion, which Darwin himself would not positively

defend, that the performances of the males have originated in an

artistic endeavour.[285] Once granted an instinctive coyness in the

hen, which must be overcome by every possible means, one can easily

understand that secondary sexual characters and activities would

gradually appear in the males. The expressive movements in which

they seek to relieve their nervous tension afford a material out of

which natural selection will shape, as the most effective means of

incitation, the various forms of display, or dance, or song. As is

well known, Wallace,[286] Spencer,[287] and Hudson[288] have even

contended that emotional pressure, or, as they put it, overflowing

vitality, by itself constitutes a sufficient explanation of the “Balz.”

In the above treatment of the question, which in its main points

accords with the conclusive researches of Professor Groos, we have

endeavoured to show that the various sorts of display never could

have reached their special and differentiated forms if it had not been

for the necessity of overcoming female coyness. But, on the other

hand, this necessity could never have created out of nothing all these

complicated activities. It is difficult—perhaps even impossible—to

make any general assertions about the relative importance of these two

explanations.[289] The only point which it is necessary to bring out

in this connection is that a sort of nuptial performance would have

appeared amongst the males even independently of its influence upon

the hen. The hygienic need of an outburst is one reason, and a very

strong one indeed, for such motor manifestations. But it seems also as

if their purpose ought not to be restricted to this cathartic effect.

The “lek” of the wood-birds tends no doubt to _increase_ nervous force

at the same time as it relieves the tension. M. Espinas thinks that the

males, when collecting in great numbers during the pairing season, are

led by an unconscious desire to stimulate their feelings by the view of

other equally excited fellow-males.[290] Such an unconscious desire of

enhancing nervous force probably lies also behind the inclination for

brilliant objects and the trifling with them in the bowers.[291] That

a sort of artificial stimulation really is necessary may perhaps be

concluded from Brehm’s general remark about the sexual life of birds:

“The pairing is often repeated, and still more often ineffectually

attempted.”[292] In a private communication to Groos, Professor

Ziegler, the eminent zoologist, also refers to the increased nervous

activity which is necessary for pairing, and the passionate preludes

which precede it in so many animals.[293]

By these two principles, viz. the necessity of overcoming the

instinctive coyness of the hen and that of stimulating the nervous

system of the cock, it is, we believe, possible to account for all the

secondary sexual characters and activities which in Darwin’s theory

necessitated the hypothesis of an animal æsthetic. When the directly

physiological importance of the nuptial preludes is acknowledged one

can also, without appealing to the effects of association, explain

the occurrence of a “lek” in birds who have already made their choice

of mate.[294] And, on the other hand, we need not give up any one

of the general results at which Darwin arrived in his researches.

Although conscious selection on the part of the hen must be denied,

the fact that she consents to couple only with the cock who has been

able to stir her feelings better than any other, constitutes a kind of

unconscious choice. It may seem unnecessary, therefore, to lay so much

stress upon the theoretical inappropriateness of Darwin’s language. The

æsthetical terms in _The Descent of Man_ could easily be exchanged for

more physiological ones without any important alteration in the main

thesis of the book. And it must even be conceded that, owing to the

extreme cautiousness which was such a remarkable peculiarity of Darwin,

this substitution would not be required in more than a few passages. He

himself often speaks of ornamental plumage as a means of “exciting,” or

“charming,” or “fascinating” the females;[295] once he even restricts

himself to saying that the hens “prefer, or are unconsciously excited

by, the more beautiful males.”[296] From the biological point of view

it would therefore be pretentious to claim any importance for this

reformulation of the Darwinian theory. But, from what must be the

dominating point of view in this work, it is by no means unnecessary

to disentangle the confusion between æsthetic appreciation and

physiological stimulation. The æsthetic corollaries, which are the

most important in this connection, will be greatly modified as soon

as the more physiological interpretation is applied to the various

manifestations of animal art.

When Darwin chose to endow the hen with an aboriginal æsthetic judgment

he was at once confronted by a difficulty which was perhaps even

greater than that of locating the beginnings of art in the animal

kingdom. The facts compelled him to admit that in some species this

æsthetic judgment seemed to be a very bad one indeed.[297] When

secondary sexual characters are regarded as signs by which the kind

and sex of the males are accentuated, this apparent inconsistency is

easily understood. The harsh cry and the inharmonious colouring of

the macaw[298] tell their tale as eloquently and convincingly as any

of the æsthetic characters of the other birds. The roaring of the

battle bump,[299] the disagreeable miauling of the peacock, and the

bleating call-note of the greenfinch[300] no doubt cause as great a

pleasure in their respective hens as is ever caused by the song of

the nightingale in his mate. That the secondary sexual characters

of the birds on the whole are so much more beautiful than those of

the mammals is not the result of any originally higher standard of

beauty with their respective females. The superiority of the birds

is quite sufficiently accounted for by the peculiar conditions of

their life, which necessitate and call forth graceful shape as well

as graceful movements. Their gorgeous colouring, on the other hand,

is undoubtedly—as has been shown above—to some extent at least

conditioned by the gaudy colouring of the tropical landscape. It must

be remarked, moreover, that notwithstanding their undeniable splendour,

the dresses of the birds by no means generally fulfil the claims of

tasteful composition. When appreciating the plumage and the songs of

the birds, we usually look upon them as pieces of nature. We admire

them as we admire the woods and flowers and every other manifestation

of nature and life. This attitude must necessarily be given up as soon

as a conscious tendency is assumed in “animal art.” When we regard the

secondary sexual characters in the manner of Darwin—as results of an

æsthetic choice—we cannot help missing all the æsthetic qualities of

harmony and composition, which are never expected, and therefore never

missed, in the objects of nature. If the proper distinction between art

and nature is maintained, it will be possible to combine an unabated

admiration for the marvels of beauty in bird life with a denial of

“animal art.”
