From an early period of life the child finds the gratification of its instinctive impulses checked or even prevented by the pressure of its environment. Conflict is thus set up between the two forces of instinctive pressure within and social pressure from without. Instinctive impulses which thus come into conflict with the repressing force are not destroyed but are deflected from their natural outlet, are repressed within the mind and ultimately prevented from rising into the conscious field at all except in disguised or symbolic forms. To the adult his childhood seems to have been altogether free from {80} any kind of sexual activity or interest, not because, as is generally supposed, such has never existed, but because it proved incapable of persisting in the conscious field and was suppressed into the unconscious with the increase of the social repressing forces. Similarly impulses experienced in adult life which are for the same reason incompatible with conscious recognition do not become conscious, but live their life in the unconscious, though they may exercise the profoundest influence on the happiness and health of the subject.

The work of Freud has been concentrated chiefly upon the one party in these conflicts—the instinctive impulse of which the only considerable one according to him is the sexual. To the other party—the repressing forces—he has given very much less attention, and in them has found apparently much less interest. By most writers of his school also they seem to be taken very much as a matter of course.

When we consider, however, what they can accomplish—how they can take the immensely powerful instinct of sex and mould and deform its prodigious mental energy—it is clear that the repressing forces are no less important than the antagonist with which they contend.

It is desirable, perhaps, to discuss a little more closely the nature of mental conflict, and especially first to define the precise meaning of the conception.

It may readily be granted that the young child’s mind is wholly egocentric, though the proposition is not without a certain element of assumption which it is not wise altogether to ignore. He experiences certain desires and impulses which he assumes with the blandest unconsciousness of any other desires but his own are there to be gratified. The failure to gratify such an impulse may come about in several ways, not all of which are equally significant in {81} establishing mental conflict. The gratification may be physically impossible. Here there is no basis for internal conflict. The resistance is wholly external; the whole child still desires its pleasure and its whole resources, mental and physical, are directed to gain the object. Mere failure may be painful and may lead to an outburst of rage which possibly even discharges some of the mental energy of the wish, but the situation psychically is simple and the incident tends of itself to go no farther.

The gratification may prove to be physically painful in itself. This seems to promise certain elements of mental conflict in balancing the pleasure of the gratification against the remembered pain it involves. We are assuming that the pain is the immediate consequence of the act, as when, for example, a child makes the immemorial scientific discovery that fire burns fingers. Such a direct experience without the interposition of a second person or the pointing of a moral does not in fact involve any real mental conflict. The source of the pain is external, its only emotional quality is that of its simple unpleasantness, and this cannot, as it were, enter into the child’s mind and divide it against itself.

True conflict, the conflict which moulds and deforms, must be actually within the mind—must be endopsychic to use a term invented by Freud, though not used by him in this exact application. In order that a desire may set up conflict it must be thwarted, not by a plain impossibility or by a mere physical pain, but by another impulse within the mind antagonizing it. It seems clear that the counter-impulse to be strong enough to contend with an impulse having in it the energy of the sex instinct must itself derive its force from some potent instinctive mechanism. We cannot suppose that the immense power of the sex impulse can be {82} controlled, moulded, and directed by any influence except such as have access to the stores of psychical energy which the instinctive activities alone possess.

We are thus led to the proposition that the essence of mental conflict is the antagonism of two impulses which both have instinct behind them, and are both, as it were, intimate constituents in the personality of the subject. Thus only can the mind become, in the worn but still infinitely appropriate metaphor, a house divided against itself. The counter-impulses to the developing sexual interest and activity of the child are, as we have seen, the result of social pressure—that is to say, the result of the influence of the human environment. This influence is manifested, not merely in direct precept, in warning, in punishment, in expressions of disapproval or disgust, but in the whole system of secrecy, of significant silences, of suppressions, of nods and winks and surreptitious signallings, of sudden causeless snubs and patently lame explanations amid which such sexual interest as the child possesses has to find a modus vivendi and an intelligible meaning.

Whence does this environmental pressure obtain the power which enables it to exercise in the child’s mind the regal functions of instinct? Clearly it can do so only if the mind possesses a specific sensitiveness to external opinion and the capacity to confer on its precepts the sanction of instinctive force. In the two earlier essays of this book I attempted to show that the essential specific characteristic of the mind of the gregarious animal is this very capacity to confer upon herd opinion the psychical energy of instinct. It is this sensitiveness, then, which lays the child’s mind open to the influence of his environment and endows for him the mental attitude of that environment with all the sanction of instinct. Thus do the repressing forces {83} become actually constituent in the child’s personality, and as much a part of his being as the egoistic desires with which they are now able to contend on equal terms.

The specific sensitiveness of the gregarious mind seems, then, to be a necessary condition for the establishment of true mental conflict, and a character which must be taken into account if we are to develop a complete theory of the evolution of the individual mind.
