Assuming the validity of the proposition that there are two primary factors in the development of the mind in each individual—the egoistic impulses of the child and his specific sensitiveness to environing influences—it may well be asked why it is that the product, the “normal” adult mind, is so uniform in its characters. It is true that this uniformity may very easily be exaggerated, for in a very considerable number of cases gross “abnormalities” are the result of the process of development, but, as I pointed out in an earlier essay, the result on the whole is to produce two broadly distinguishable types of mind—the unstable and the stable—the latter on account of its numerical superiority being also dignified as normal. A considerable uniformity in the final products must therefore be accepted. If, however, environmental influences are an essential factor in the production of this result, there seems no little difficulty in accounting for the uniformity seeing that environments vary so much from class to class, nation to nation, and race to race. Where, we may ask, is the constant in the environmental factors which the uniformity of the outcome leads us to expect? Assuming with Freud that of the egoistic impulses of the child, the sexual alone seriously counts in the formation of character, can it be shown that the influences which surround the child are uniform {84} in their general direction against this? At first sight it would seem certainly not. Even in the same country the variations in taste, reticence, modesty, and morality towards matters of sex interest vary greatly from class to class, and presumably are accompanied by corresponding variations in the type of influence exercised by the environment of the child.
Adequately to deal with this difficulty would involve examining in detail the actual mental attitude of the adult towards the young, especially in regard to matters directly or indirectly touching upon interests of sex. The subject is a difficult one, and if we limit ourselves to the purely human standpoint, ugly and depressing. The biologist, however, need not confine himself to so cramped an outlook, and by means of collecting his observations over a much larger field is able to some extent to escape the distorting effects of natural human prejudice. Viewed in a broad way, it is neither surprising nor portentous that there should naturally exist a strong and persistent jealousy between the adult and the young. Indeed, many of the superficial consequences of this fact are mere commonplaces. Throughout most of the lower animals the relation is obvious and frankly manifested. Indeed, it may be regarded as a more or less inevitable consequence of any form of social life among animals. As such, therefore, it may be expected to appear in some form or other in the human mind. The manifestations of it, however, will by no means necessarily take easily recognizable forms. The social pressure to which the mind is subject will tend to exclude such a feeling from at any rate full consciousness, and such manifestations as are allowed it will be in disguised and distorted forms.
It seems difficult to avoid the conclusion that some dim and unrealized offshoot of such a jealousy {85} between adult and young is responsible for the unanimity with which man combines to suppress and delay the development of any evidence of sexual interest by the young. The intensity of the dislike which is felt for admitting the young to share any part of the knowledge of the adult about the physiology of sex is well illustrated by the difficulty parents feel in communicating to their children some of the elementary facts which they may feel very strongly it is their duty to impart. A parent may find himself under these circumstances trying to quiet his conscience with all sorts of excuses and subterfuges while he postpones making the explanations which duty and affection urge upon him as necessary for the health and happiness of his child. An unwillingness so strong and irrational as this must have its root in subconscious processes charged with strong feeling.
The tendency to guard children from sexual knowledge and experience seems to be truly universal in civilized man and to surpass all differences of morals, discipline, or taste. Amongst primitive savages the principle has not acquired the altruistic signification which civilized man has given it, but operates as a definite exclusion to be overcome only by solemn ceremonies of initiation and at the price of submission to painful and sometimes mutilating rites.
The constancy of attitude of the adult towards the young, which is thus seen to be so general, evidently gives to the environmental influences which surround the child a fundamental uniformity, and as we have seen, the theory of the development of the individual mind demands that such a uniformity of environmental influence should be shown to be in action.
This is no place to follow out the practical consequences of the fact that every adult necessarily {86} possesses a primary bias in his attitude towards the young, and a bias which is connected with instinctive impulses of great mental energy. However much this tendency is overlaid by moral principles, by altruism, by natural affection, as long as its true nature is unrecognized and excluded from full consciousness its influence upon conduct must be excessive and full of dangerous possibilities. To it must ultimately be traced the scarcely veiled distrust and dislike with which comparative youth is always apt to be met where matters of importance are concerned. The attitude of the adult and elderly towards the enthusiasms of youth is stereotyped in a way which can scarcely fail to strike the psychologist as remarkable and illuminating in its commonplaceness. The youthful revolutionary, who after all is no more essentially absurd than the elderly conservative, is commonly told by the latter that he too at the same age felt the same aspirations, burnt with the same zeal, and yearned with the same hope until he learnt wisdom with experience—“as you will have, my boy, by the time you are my age.” To the psychologist the kindly contempt of such pronouncements cannot conceal the pathetic jealousy of declining power. Herd instinct, inevitably siding with the majority and the ruling powers, has always added its influence to the side of age and given a very distinctly perceptible bias to history, proverbial wisdom, and folklore against youth and confidence and enterprise and in favour of age and caution, the immemorial wisdom of the past, and even the toothless mumblings of senile decay.
Any comprehensive survey of modern civilized life cannot fail to yield abundant instances of the disproportionate influence in the conduct of affairs which has been acquired by mere age. When we remember how little in actual practice man proves himself capable of the use of reason, how very little {87} he actually does profit by experience though the phrase is always in his mouth, it must be obvious that there is some strong psychological reason for the predominance of age, something which must be determinative in its favour quite apart from its merits and capacity when competing with youth. The “monstrous regiment” of old men—and to the biologist it is almost as “monstrous” as the regiment of Mary Stuart was to poor indignant Knox—extends into every branch of man’s activity. We prefer old judges, old lawyers, old politicians, old doctors, old generals, and when their functions involve any immediacy of cause and effect and are not merely concerned with abstractions, we contentedly pay the price which the inelasticity of these ripe minds is sometimes apt to incur.
IV
If the propositions already laid down prove to be sound, we must regard the personality of the adult as the resultant of three groups of forces to which the mind from infancy onwards is subject; first the egoistic instincts of the individual pressing for gratification and possessing the intense mental energy characteristic of instinctive processes, secondly the specific sensitiveness to environmental influences which the mind as that of a gregarious animal necessarily possesses, a quality capable of endowing outside influences with the energy of instinct and, thirdly the environmental influences which act upon the growing mind and are also essentially determined in their intensity and uniformity by instinctive mechanisms.
The work of Freud has been directed mainly to the elucidation of the processes included in the first group—that is to say, to the study of the primarily egoistic impulses and the modifications {88} they develop under restraint. He has worked out, in fact, a veritable embryology of the mind.
