This is of considerable interest, since it appears that in man too the

largest class of sexually abnormal individuals are those whose external

appearance is almost or quite feminine, but who possess male instincts.

It is at least probable that examination will show that they, too, or

many of them, will be of the type described above--males with delayed

activation of testis, a consequent classification as female at birth,

and a girl’s upbringing, with male instincts arising in the unhappy

creature at puberty.

It is the fashion nowadays to write down abnormal sexual psychology

wholly to the account of the mind, to an abnormal development with

causes entirely psychological. It is clear, however, that if some

abnormal individuals can be cured by implantation, and others are

abnormal owing to an early failure of activation, this conception falls

to the ground, and the Freudian is robbed of some of his most cherished

examples.

In any case, the work on animals definitely shows that, unless the

mechanism of activation of instinct by gonad secretion has altered

between animal and man more than we have any right to postulate a

priori, the quality of gonad secretion and the balance of all the

endocrines has to be taken into account far more than is done by the

average psycho-analyst.

This, however, is not to say that the genesis of our attitude towards

sex, our sexual behaviour, and our general mental organization in so

far as modified by sex, is not normally determined for the most part

by purely psychological causes. If there is a physical abnormality,

this will react upon the mental; but in the vast majority of cases

the physical variation will not take the individual beyond the limits

of normality, and when the normal physical limits are not exceeded,

the wide range of mental variation still observable is to be ascribed

to psychological causes. In other words, abnormal sexual behaviour

and instinct may be due either to physiological or psychological

abnormality, and the latter is probably the commoner cause.

I am not competent to attempt to treat of the vast and complex

psychological aspect of the sex-problem which the analytical

psychologists have opened up to such an extent within the last few

years; I can only deal with it in the broadest way, and content myself

rather with stating than with solving problems.

As regards the place of sex in our mental organization, there are two

contradictory extremes possible. Either all ideas connected with the

physical side of sex may be repressed with great vehemence, and the

sexual contribution to various emotions ignored or dismissed, while a

constant attempt is made at sublimation; or else there is little or no

repression beyond that necessitated by convention and custom, sexual

matters are taken at their physical face value, and sublimation is not

consciously attempted and exists only to a negligible amount.

There is no doubt that the first alternative represents one of the

commonest neuroses of modern life, and one in which an interpretation

on principles made familiar by psycho-analysis is the most

satisfactory. Repression, through whatever cause initiated (and

psychologists, I understand, are coming more and more to recognize

that chronic misuse of the mind as well as single violent shocks may

be effective), leads to a more or less complete dissociation of two

parts of the mind, of which one only is in the main connected with

the conscious personal life. As a result, curious phenomena are met

with. There is, it is true, a constant effort necessary to keep life

a-going with the aid of an incomplete mental organization; but when

satisfaction is attained, its very rarity brings with it a certain

glow, an irradiation of peculiarly pleasurable nature. Furthermore,

dissociation in most cases is not complete; now and again, and

especially when there is successful sublimation--in some people when in

love, in others with religious ecstasy, in others again with some form

of art--now and again re-association of the parts occurs, and there is

an extraordinary sense of the irruption of some vast beneficent force,

some great extra-personal flood of soul, into the meagre stream of

everyday life. The lives of a certain number of saints and ascetics,

mystics and poets, abound with phenomena of this sort; and apparently

the sense of value attaching to the occasional complete attainment of

such satisfactory states of the soul, combined with the conscious daily

quest for sublimation which is inevitable when the most important part

of the primitive emotions are repressed, is such a vivid experience

that it satisfies the mind and enables such persons to carry on, and to

do work sometimes of the highest value.

On the other hand, men and women with this type of mental development

naturally tend to be unstable; they cannot be sure of their capacity,

whether for routine work or creative thought or spiritual experience,

from day to day. Their mental life has a tendency to wear thin, their

sense of effort and struggle to increase and lead to breakdown. It

is in the long run an unsatisfactory way of organizing the psyche,

because the conscious mind has less than it ought to have upon which to

fall back.

The opposite extreme is equally unsatisfactory. If individuals of the

first type are trying to build high without adequate foundations, those

of the second are mistaking the foundations for a complete building.

A dissociation of a different type occurs in them--a dissociation due

to lack of use, to a mere failure to connect up that part of the mind

concerned with sexual emotion with a great many of the mind’s other

activities. Thus the sexual side has few and lower values associated

with it than it might, and other possibilities of thought and feeling

and action remain as mere possibilities, never realized in actuality.

The result is a definitely incomplete personality of a more or less

arrested or rudimentary type.

Those are the extremes: of course there are all intermediates between

them. They may crop up with apparent spontaneity, determined more

by the hereditary constitution of the man or woman than by external

happenings: or they may be mainly or at least largely determined by the

accidents of the environment during the period before maturity. One

of the most potent factors in the environment will be the attitude of

the parents towards sexual matters. On the one hand they may adopt the

common, horror-stricken attitude towards sex, hushing it up, making

it clear to the sensitive mind of childhood that there is something

thoroughly bad about it, and so laying the best possible foundations

for future repression. Or, on the other hand, they may openly adopt

the psycho-analytic view as to the rôle of sex in the development of

mind, may further believe that the fullest analysis and self-knowledge

is always desirable, and may accordingly be pointing out to the

child interpretations of its actions and sayings in terms of sex,

familiarizing it with sex from the outset, not merely not discouraging

but actually encouraging reference to sexual matters. This will tend,

_ceteris paribus_, to the development of a mind in which many of the

more complex mental operations will not usually persist because the

subject will be continually unbuilding them into their constituent

parts, of which sex will be the most unvarying and important.

Both these types are to my judgment obviously unsatisfactory. The ideal

organization of the mind must be one in which first there is a minimum

of waste of energy, secondly a maximum realization of potentiality.

The operations of mind may further be thought of from two different

angles--a subserving the biological needs of the organism, or as

ends in themselves. From the first point of view, thought is action

_in posse_: efficiency and full utilization of energy are here the

requirements, and it is obvious that any method which even partially

separates one part of the mental organization from the rest must be a

poor one, that a refusal to face any portion of reality, such as, in

our special case, the physical side of sex, must put the organism at a

disadvantage in a world in which that portion of reality plays, as it

obviously does, an important rôle.

The correct type of organization is one of the type which has been

developed over and over again in the course of evolution, for

different functions: it is the hierarchical one, in which some parts

are dominant, others subordinate, the dominant parts helpless without

the subordinate, the subordinate different, through the fact of their

subordination, from what they would otherwise have been, doing most of

the hard work, but under the guidance of the dominant. Only in this way

is a unitary organization arrived at in which there is the minimum of

waste, of antagonism between the parts.

The psycho-analysts have, by analysing the pathology of mind, shown

us how waste of energy may arise in particular cases, and so make it

easier for us to avoid it in general.

One may recognize the merits of Freud as an investigator without

accepting all or even the majority of his conclusions. As the late

W. H. Rivers pointed out, Freud will always be remembered in the

history of psychology because he introduced new ideas and new methods

into the science. Previous workers had discovered the realm of the

subconscious; but they had not discovered the real nature of its

relation to the rest of the mental organization. Freud pointed out

that there was often a biological value attached to the power of

forgetting as well as to that of remembering, and that in any case

in most of us a large amount of experience is rendered unconscious by

suppression, or an attempt made to force it into the unconscious by

repression. He and his followers and other schools of psychologists

have pointed out the importance of unresolved conflicts in determining

thought and behaviour, and have made it clear that in the ordinary

civilized community of to-day a large proportion of those conflicts

arise out of difficulties connected with the sex-instinct. And, even

if we reject the extreme claims made by many Freudians, we must admit

that psycho-analysis has shown that many cases of actual perversion

of instinct may be cured by analytic methods, and that sex occupies a

very much larger space in the mind than was previously supposed. It

had not been previously supposed, because of the fact that it tends to

appear in consciousness in disguised form--either sublimated and thus

intertwined with other emotions and instincts or with unusual objects,

or else rationalized as something else, or kept below the surface of

consciousness as an unfulfilled wish; and because there is a resistance

in most of us to recognizing its importance.

This revolution in our thought has proved very unpalatable to many. In

just the same way as a large proportion of Darwin’s opponents opposed

him because they believed that to accept man’s simian origin was a

repulsive degradation, so many of the opponents of psycho-analysis

oppose it because they believe that to ascribe this huge rôle to sex

in the genesis of our psyche is a repulsive degradation.

To my mind there are two very general questions which the student of

human sex psychology now has to face, if he takes not necessarily

the whole but the central theses of psycho-analysis, however much

pruned, as proven. The first is this: granted that sex does play such

a large part, especially in early years, in the genesis of our mental

organization, is it desirable that the average adult or adolescent

should, by analysis, be given full self-knowledge on the subject?

The second is this: granted that sex does penetrate into more corners

of mind in man than in lower organisms, is this really a regrettable

thing, or can we find any grounds for believing it to be desirable or

biologically progressive?

To answer this we shall have to go back a little to first principles,

and consider, however briefly, certain facts as to the march of

evolution.

Evolution is essentially progressive. It proceeds on the whole in

a certain direction, and that direction is on the whole towards a

realization of what seems to us to have positive value. The direction,

however, as a matter of fact, is most striking when we consider the

maximum level attained, much less so when we consider the average, not

at all when we look at the minimum.

The method or mechanism of progress may differ in different types,

and it does differ in man from that which is found in other mammals.

In most higher animals progress is brought about chiefly by natural

selection operating upon individuals, although in a few forms selection

operates chiefly upon groups of communities: in both cases the changes

in the inherited constitution of the species are the important

changes. In man, however, in all except the very early stages of

his development, changes in inherited constitution have been small

and unimportant, and the chief changes of evolutionary significance

have been those in tradition; selection among individuals has been

of relatively little importance, and selection has fallen mainly

upon groups and, to an ever-increasing extent, upon their ideas and

traditions.

In spite of differences in method as between different types of

organism, the tendency has been in the same direction--towards

a possibility of greater control, greater independence, greater

complexity, and greater regulation or harmony.

Looked at from the evolutionary point of view, the moving, dynamic

point of view, we have to think of human sex-psychology in yet another

way. So far we have been treating it as what it is; now we must think

of what it may become.

The general rule in evolution--the natural and obvious rule--is that

acquisitions are not thrown away when change occurs, but built upon,

utilized for some new function. The endostyle of the lowest chordates,

part of a very primitive type of feeding mechanism, was converted,

when they changed their mode of life, into the thyroid gland: the

parathyroids develop from the remains of the gill-apparatus when

gills are discarded for lungs: the secondary sexual differences which

originate as accidental consequence of the primary difference between

the sexes are, over and over again, elaborated into special characters

employed in courtship.

So the sex-instinct and its associated emotion, at first simply one

among a number of separate and scarcely-correlated instincts, has in

man become the basis for numerous new mental functions. It can enter

into the composition of various emotions, though its character is often

disguised and its presence often undetected. It contributes to some of

the most exalted states of mind which we can experience. The sexual

relationship, which in lower animals involves neither contact nor even

propinquity, but simply simultaneous discharge of reproductive cells,

and in most animals is a purely temporary affair, is very different

in man. Even in those birds and non-human mammals in which the sexes

remain associated for long periods or permanently, the different

departments of life are more in water-tight compartments, the psychical

activity is subordinate to the physiological: in man the physiological

side, though of course still basic and necessary, is more--and can

be much more--subordinate to the psychological, and all parts of the

mental life interpenetrate to a much greater extent; so that the

sex-instinct may become transformed by a psychological process roughly

analogous to the transformation of physical energy, and reappear in

altered guise in various other activities of mind.

If we look at the matter broadly, we see that man is in a period of

evolutionary transition as regards sex. We found previously that the

greatest change connected with sex which has been made in the evolution

of higher animals was the change by which there was evolved a brain

and mind with associated sense-organs in which accurate perception of

objects at a distance could occur, a mechanism which really dominated

the working of the organism as a whole, and in which memory and emotion

seemed to play an important part. Once this happened, the sex-instinct

could be linked up with general emotional reactions and connected with

external objects capable of inducing emotion.

What was the result? That in every group possessing such a type of

mind, epigamic characters of a beautiful or striking or bizarre

nature were evolved. This first linking-up of sex with mind produced,

eventually, a large proportion of the beauty of the organic world. It

coloured and adorned not only many a bird, but even newts and fish

and spiders; it helped elicit song and music from mere sounds and

noises; it moulded our own bodies, coloured our lips and eyes, and

everywhere helped in adding grace to mere serviceableness; it saw to it

that, as St. Paul puts it, “even our uncomely parts have an abundant

comeliness.” But, as we have just pointed out, its connection with the

mind’s higher centres was in all pre-human forms still temporary, under

the control of cyclical physiological changes, and the mind as a whole

was still constructed in compartments, so that different instincts

and different experiences did not necessarily or even usually come in

contact with each other.

The next great change is being made now; it concerns a further

development of mind and a consequent fresh mode of connection of sex

with mental life. As we have outlined above, this change in mind

consists in the tendency towards uniting the different parts of the

psyche, both those portions given by heredity and the modification due

to experience, into a single organic whole, and in making this whole

more dominant over the other aspects of the organism; the consequent

tendency as regards the relationship of sex to the organism is towards

taking it out of its single groove, its water-tight compartment, and

bringing it into more complete and more permanent union with the rest

of the mind. Furthermore, the main change and the consequent change as

regards sex are both of a biologically progressive nature.

We are now, I think, owing to our taking this broad biological view,

in a better position to make up our minds as to some at least of the

difficulties which beset us to-day in any attempt to deal squarely

with the relation of sex to human life. It is true that some of

these difficulties are permanent. The synthesis of a unitary and

comprehensive mental organization can never be an easy task. The

child is endowed with a number of instinctive tendencies which, as

in animals, each tend whenever aroused to occupy the whole mental

field to the exclusion of all others, producing divergence and lack

of co-ordination instead of unity and organization. Then again, the

experience of any one individual may be highly unusual. For the child

to co-ordinate his various tendencies with each other and with his

own experience and with the tradition and experience of the race must

always be difficult, and there will always be some failures.

There is another permanent difficulty, a biological disharmony, in the

fact that sexual maturity in man comes several years before general

maturity, and that again, at least in any state of civilization which

we can at present imagine as practicable, several years before the

economic possibility of marriage. There will always be crises of

adolescence; there will always be suffering and difficulty due to this

disharmony in time between the origin of the full sexual instinct and

the possibility of its proper satisfaction.

However, granted these permanent difficulties, there are others which

may be reduced or made to disappear. Granted that we have to organize

our minds into a whole, we can see the general plan on which we

should aim at organizing it. We must aim first at having no barriers

between different parts of the mind. Every attempt must be made in

the education of children to prevent there being a stigma attached

to one whole section of mental life, and so to avoid its partial or

total dissociation from the rest. On the other hand, the absence of

barriers does not imply the absence of any relation of subordination or

dominance of one part to another. One of the most important biological

generalizations is that progressive evolution is accompanied by the

rise of one part to dominance and, whenever there are many parts to be

considered, by the arrangement of the rest in some form of hierarchy,

each part being subordinate to one above, dominant to one below. It

is such a hierarchy which we must try to construct in our mental

organization.

It is obviously impossible here to go into the whole question of

values and ideals, but it is clear to any one who has given the

briefest reflection to the subject that there are certain values,

æsthetic, intellectual, and moral, which are ultimate for the mind of

man, certain ideals--of truth and honesty, intellectual satisfaction,

righteousness or at least freedom from the sense of sin or guilt,

completeness and self-realization, unselfishness and serviceableness

and so forth--which (though perhaps in varying proportions) are by

common consent accepted as the highest: and further that the greater

the attempt to deepen and broaden these, to increase their mental

intensity and to widen their range and association, the more they

tend to emerge into something increasingly unitary, in which it is

seen that honesty is also beautiful and useful, that intellectual

satisfaction is in the long run serviceable to the community, that

unselfishness to be effective requires thought and will besides mere

altruistic emotion, that one of the greatest aids to any genuine

righteousness is an æsthetic love of beautiful things that prevents our

doing ugly things, and so _ad infinitum_.

The proper way, then, to build the sex instinct into the mental system

is not to have its stimulation cause a merely physiological and

uninhibited desire for its gratification, nor to bring about a forcible

repression and an attempt to break connection between it and the other

parts of the mind.

The desirable method is to have free connection between it and the

dominant ideas, so that its stimulation brings about a stimulation of

them too. This leads, as a matter of experience, to the incorporation

of the sexual emotion in the dominant ideas, or we had better say an

interpenetration of one with the other, so that the sexual emotion is

no longer simply sexual emotion, but is become part of something very

much larger and very much better. Let the great writers say in their

few words what I should say much worse in many.

Wordsworth’s “sense sublime of something far more deeply interfused”

opens a window on to the general process of sublimation: and Blake’s

description of the physical union of the sexes as “that ... on which

the soul expands her wing” is an epitome of a particular aspect of

our particular problem. Or again, when St. Paul says “Am I not free?”

or “All things are lawful unto me,” he means that by subordinating all

sides of himself to his highest ideals, he has reached that state in

which what he does is right to him because he only wants to do what

is right. (True that, as he himself confesses, he is not always able

to keep in that state: but when he is in it, he attains that complete

freedom which is the subordination of lower to higher desire.)

Physiologically speaking, the activation of the sex instinct, when the

connection is made in this way, arouses the higher centres, and these

react upon the centres connected with the sex instinct, modifying their

mode of action. The nett result is thus that both act simultaneously

to produce a single whole of a new type. Processes of this nature

are common in the nervous system, as has been shown for instance by

Hughlings Jackson, Head, and Rivers.[39]

Thus the higher, dominant parts of the mind are strengthened by their

connection with such lower parts as the simple sex instinct, and the

sex instinct is able to play a rôle in any operation of the mind,

however exalted, in which emotion is in any way concerned. Rivers

believes that the actual conflict between controlled and controlling

parts of the mind is a potent generator of mental “energy”; and adds,

“whatever be the source of the energy, however, we can be confident

that by the process of sublimation the lives upon which it is expended

take a special course, and in such case it is not easy to place any

limit to its activity. We do not know how high the goal that it may

reach.”[40]
