Freud, “The Resistances to Psycho-Analysis” (1925 )
“Human civilization rests upon two pillars, of which one is the control of natural forces and the other the restriction of our instincts. The ruler’s throne rests upon fettered slaves. Among the instinctual components which are thus brought into service, the sexual instincts, in the narrower sense of the word, are conspicuous for their strength and savagery. Woe, if they should be set loose! The throne would be overturned and the ruler trampled under foot. Society is aware of this—and will not allow the topic to be mentioned.
But why not? What harm could the discussion do? Psycho-analysis has never said a word in favour of unfettering instincts that would injure our community; on the contrary it has issued a warning and an exhortation to us to mend our ways. But society refuses to consent to the ventilation of the question, because it has a bad conscience in more than one respect. In the first place it has set up a high ideal of morality—morality being restriction of the instincts—and insists that all its members shall fulfill that ideal without troubling itself with the possibility that obedience may bear heavily upon the individual. Nor is it sufficiently wealthy or well-organized to be able to compensate the individual for the amount of his instinctual renunciation. It is consequently left to the individual to decide how he can obtain, for the sacrifice he has made, enough compensation to enable him to preserve his mental balance. On the whole, however, he is obliged to live psychologically beyond his means, while the unsatisfied claims of his instincts make him feel the demands of civilization as a constant pressure upon him. Thus society maintains a condition of cultural hypocrisy which is bound to be accompanied by a sense of insecurity and a necessity for guarding what is an undeniably precarious situation by forbidding criticism and discussion. This line of thought holds good for all the instinctual impulses, including, therefore, the egoistic ones. The question whether it applies to all possible forms of civilization, and not merely to those which have evolved hitherto, cannot be discussed here.”
