This point, however, calls for elucidation. Here is the way in which I see it. The cultural development of mankind (some, I know, prefer to call it civilization) has been in progress since immemorial antiquity. To this processus we owe all that is best in our composition, but also much that makes for human suffering. Its origins and causes are obscure, its issue is uncertain, but some of its characteristics are easy to perceive. It well may lead to the extinction of humanity for it impairs the sexual function in more than one respect, and even today the uncivilized races and the backward classes of all nations are multiplying more rapidly than “the cultured elements.” This process may, perhaps, be likened to the effects of domestication on certain animals—it clearly involves physical changes of structure—but the view that cultural development is an “organic” process of this order has not yet become generally familiar. The psychic changes which accompany this process of cultural change are striking, and not to be gainsaid. They consist in the progressive rejection of instinctive ends and a scaling down of instinctive reactions. Sensations which delighted our forefathers have become neutral or unbearable to us; and, if our ethical and aesthetic ideals have undergone a change, the causes of this are “ultimately organic.” On the psychological side two of the most important phenomena of culture are, firstly, a strengthening of the intellect, which tends to master our instinctive life, and, secondly, an introversion of the aggressive impulse, with all its consequent benefits and perils. Now war runs most emphatically counter to the psychic disposition imposed on us by the growth of culture; we are therefore bound to resent war, to find it utterly intolerable. With pacifists like us it is not merely an intellectual and affective repulsion, but a constitutional intolerance, an idiosyncrasy in its most drastic form. And it would seem that the aesthetic ignominies of warfare play almost as large a part in this repugnance as war’s atrocities. How long have we to wait before the remainder of humanity turns pacifist? Impossible to say, and yet perhaps our hope that these two factors—people’s cultural disposition and a well-founded dread of the form that future wars will take—may serve to put an end to war in the near future, is not chimerical. But by what ways or by-ways this will come about, we cannot guess. Meanwhile we may rest on the assurance that whatever makes for cultural development is working also against war.
With kindest regards and, should this exposé prove a disappointment to you, my sincere regrets,
Yours, Sigmund Freud
