Sublimation of instinct is an especially conspicuous feature of cultural development; it is what makes it possible for higher psychical activities, scientific, artistic or ideological, to play such an important part in civilized life. If one were to yield to a first impression, one would say that sublimation is a vicissitude which has been forced upon the instincts entirely by civilization. But it would be wiser to reflect upon this a little longer. In the third place, finally, and this seems the most important of all, it is impossible to overlook the extent to which civilization is built up upon a renunciation of instinct, how much it presupposes precisely the non-satisfaction (by suppression, repression or some other means?) of powerful instincts. This cultural frustration dominates the large field of social relationships between human beings;we know already that it is the cause of the antagonism against which all civilization has to fight.
