Sexual Selection In Man

By HAVELOCK ELLIS
As in many other of these _Studies_, and perhaps more than in most, the
task attempted in the present volume is mainly of a tentative and
preliminary character. There is here little scope yet for the presentation
of definite scientific results. However it may be in the physical
universe, in the cosmos of science our knowledge must be nebulous before
it constellates into definitely measurable shapes, and nothing is gained
by attempting to anticipate the evolutionary process.
Thus it is that
here, for the most part, we have to content ourselves at present with the
task of mapping out the field in broad and general outlines, bringing
together the facts and considerations which indicate the direction in
which more extended and precise results will in the future be probably
In his famous _Descent of Man_, wherein he first set forth the doctrine of
sexual selection, Darwin injured an essentially sound principle by
introducing into it a psychological confusion whereby the physiological
sensory stimuli through which sexual selection operates were regarded as
equivalent to æsthetic preferences. This confusion misled many, and it is
only within recent years (as has been set forth in the
"Analysis of the
Sexual Impulse" in the previous volume of these _Studies_) that the
investigations and criticisms of numerous workers have placed the doctrine
of sexual selection on a firm basis by eliminating its hazardous æsthetic
element. Love springs up as a response to a number of stimuli to
tumescence, the object that most adequately arouses tumescence being that
which evokes love; the question of æsthetic beauty, although it develops
on this basis, is not itself fundamental and need not even be consciously
present at all. When we look at these phenomena in their broadest
biological aspects, love is only to a limited extent a response to beauty;
to a greater extent beauty is simply a name for the complexus of stimuli
which most adequately arouses love. If we analyze these stimuli to
tumescence as they proceed from a person of the opposite sex we find that
they are all appeals which must come through the channels of four senses:
touch, smell, hearing, and, above all, vision. When a man or a woman
experiences sexual love for one particular person from among the multitude
by which he or she is surrounded, this is due to the influences of a group
of stimuli coming through the channels of one or more of these senses.
There has been a sexual selection conditioned by sensory stimuli. This is
true even of the finer and more spiritual influences that proceed from one
person to another, although, in order to grasp the phenomena adequately,
it is best to insist on the more fundamental and less complex forms which
they assume. In this sense sexual selection is no longer a hypothesis
concerning the truth of which it is possible to dispute; it is a
self-evident fact. The difficulty is not as to its existence, but as to
the methods by which it may be most precisely measured.
fundamentally a psychological process, and should be approached from the
psychological side. This is the reason for dealing with it here. Obscure
as the psychological aspects of sexual selection still remain, they are
full of fascination, for they reveal to us the more intimate sides of
human evolution, of the process whereby man is molded into the shapes we

SEXUAL SELECTION IN MAN.
The External Sensory Stimuli Affecting Selection in Man-
-The Four Senses
Tumescence--the process by which the organism is brought into the physical
and psychic state necessary to insure conjugation and detumescence--to
some extent comes about through the spontaneous action of internal forces.
To that extent it is analogous to the physical and psychic changes which
accompany the gradual filling of the bladder and precede its evacuation.
But even among animals who are by no means high in the zoölogical scale
the process is more complicated than this. External stimuli act at every
stage, arousing or heightening the process of tumescence, and in normal
human beings it may be said that the process is never completed without
the aid of such stimuli, for even in the auto-erotic sphere external
stimuli are still active, either actually or in imagination.
The chief stimuli which influence tumescence and thus direct sexual choice
come chiefly--indeed, exclusively--through the four senses of touch,
smell, hearing, and sight. All the phenomena of sexual selection, so far
as they are based externally, act through these four senses. The
reality of the influence thus exerted may be demonstrated statistically
even in civilized man, and it has been shown that, as regards, for
instance, eye-color, conjugal partners differ sensibly from the unmarried
persons by whom they are surrounded. When, therefore, we are exploring the
nature of the influence which stimuli, acting through the sensory
channels, exert on the strength and direction of the sexual impulse, we
are intimately concerned with the process by which the actual form and
color, not alone of living things generally, but of our own species, have
been shaped and are still being shaped. At the same time, it is probable,
we are exploring the mystery which underlies all the subtle appreciations,
all the emotional undertones, which are woven in the web of the whole
world as it appeals to us through those sensory passages by which alone it
can reach us. We are here approaching, therefore, a fundamental subject of
unsurpassable importance, a subject which has not yet been accurately
explored save at a few isolated points and one which it is therefore
impossible to deal with fully and adequately. Yet it cannot be passed
over, for it enters into the whole psychology of the sexual instinct.
Of the four senses--touch, smell, hearing, and sight--
with which we are
here concerned, touch is the most primitive, and it may be said to be the
most important, though it is usually the last to make its appeal felt.
Smell, which occupies the chief place among many animals, is of
comparatively less importance, though of considerable interest, in man; it
is only less intimate and final than touch. Sight occupies an intermediate
position, and on this account, and also on account of the very great part
played by vision in life generally as well as in art, it is the most
important of all the senses from the human sexual point of view. Hearing,
from the same point of view, is the most remote of all the senses in its
appeal to the sexual impulse, and on that account it is, when it
intervenes, among the first to make its influence felt.
 Taste must, I believe, be excluded, for if we abstract the parts of
touch and smell, even in those abnormal sexual acts in which it may seem
to be affected, taste could scarcely have any influence.
Most of our
"tasting," as Waller puts it, is done by the nose, which, in man, is in
specially close relationship, posteriorly, with the mouth. There are at
most four taste sensations--sweet, bitter, salt, and sour--if even all of
these are simple tastes. What commonly pass for taste sensations, as shown
by some experiments of G.T.W. Patrick (_Psychological Review_, 1898, p.
160), are the composite results of the mingling of sensations of smell,
touch, temperature, sight, and taste.

We are accustomed to regard the skin as mainly owing its existence to the
need for the protection of the delicate vessels, nerves, viscera, and
muscles underneath. Undoubtedly it performs, and by its tough and elastic
texture is well fitted to perform, this extremely important service. But
the skin is not merely a method of protection against the external world;
it is also a method of bringing us into sensitive contact with the
external world. It is thus, as the organ of touch, the seat of the most
widely diffused sense we possess, and, moreover, the sense which is the
most ancient and fundamental of all--the mother of the other senses.
It is scarcely necessary to insist that the primitive nature of the
sensory function of the skin with the derivative nature of the other
senses, is a well ascertained and demonstrable fact. The lower we descend
in the animal scale, the more varied we find the functions of the skin to
be, and if in the higher animals much of the complexity has disappeared,
that is only because the specialization of the various skin regions into
distinct organs has rendered this complexity unnecessary. Even yet,
however, in man himself the skin still retains, in a more or less latent
condition, much of its varied and primary power, and the analysis of
pathological and even normal phenomena serves to bring these old powers
into clear light.
Woods Hutchinson (_Studies in Human and Comparative Pathology_,
1901, Chapters VII and VIII) has admirably set forth the immense
importance of the skin, as in the first place "a tissue which is
silk to the touch, the most exquisitely beautiful surface in the
universe to the eye, and yet a wall of adamant against hostile
attack. Impervious alike, by virtue of its wonderful responsive
vitality, to moisture and drought, cold and heat, electrical
changes, hostile bacteria, the most virulent of poisons and the
deadliest of gases, it is one of the real Wonders of the World.
More beautiful than velvet, softer and more pliable than silk,
more impervious than rubber, and more durable under exposure than
steel, well-nigh as resistant to electric currents as glass, it
is one of the toughest and most dangerproof substances in the
three kingdoms of nature" (although, as this author adds, we
"hardly dare permit it to see the sunlight or breathe the open
air"). But it is more than this. It is, as Woods Hutchinson
expresses it, the creator of the entire body; its embryonic
infoldings form the alimentary canal, the brain, the spinal cord,
while every sense is but a specialization of its general organic
activity. It is furthermore a kind of "skin-heart,"
circulation by its own energy; it is the great heat-regulating
organ of the body; it is an excretory organ only second to the
kidneys, which descend from it, and finally it still remains the
seat of touch.
It may be added that the extreme beauty of the skin as a surface
is very clearly brought out by the inadequacy of the comparisons
commonly used in order to express its beauty. Snow, marble,
alabaster, ivory, milk, cream, silk, velvet, and all the other
conventional similes furnish surfaces which from any point of
view are incomparably inferior to the skin itself.
_Die Schönheit des Weiblichen Körpers_, Chapter XII.)
With reference to the extraordinary vitality of the skin,
emphasized by Woods Hutchinson, it may be added that, when
experimenting on the skin with the electric current, Waller found
that healthy skin showed signs of life ten days or more after
excision. It has been found also that fragments of skin which
have been preserved in sterile fluid for even as long as nine
months may still be successfully transplanted on to the body.
(_British Medical Journal_, July 19, 1902.) Everything indicates, remark Stanley Hall and Donaldson ("Motor
Sensations in the Skin," _Mind_, 1885), that the skin is "not
only the primeval and most reliable source of our knowledge of
the external world or the archæological field of psychology," but
a field in which work may shed light on some of the most
fundamental problems of psychic action. Groos (_Spiele der
Menschen_, pp. 8-16) also deals with the primitive character of
Touch sensations are without doubt the first of all the sensory
impressions to prove pleasurable. We should, indeed, expect this
from the fact that the skin reflexes have already appeared before
birth, while a pleasurable sensitiveness of the lips is doubtless
a factor in the child's response to the contact of the maternal
nipple. Very early memories of sensory pleasure seem to be
frequently, perhaps most frequently, tactile in character, though
this fact is often disguised in recollection, owing to tactile
impression being vague and diffused; there is thus in Elizabeth
Potwin's "Study of Early Memories" (_Psychological Review_,
November, 1901) no separate group of tactile memories, and the
more elaborate investigation by Colegrove ("Individual Memories,"
_American Journal of Psychology_, January, 1899) yields no
decisive results under this head. See, however, Stanley Hall's
valuable study, "Some Aspects of the Early Sense of Self,"
_American Journal of Psychology_, April, 1898. Külpe has a
discussion of the psychology of cutaneous sensations (_Outlines
of Psychology_ [English translation], pp. 87 et seq.)
