“It is impossible to overlook the extent to which civilization is built up upon a renunciation of instinct....”

“Actually, the substitution of the reality-principle for the pleasure-principle denotes no dethronement of the pleasure-principle, but only a safeguarding of it. A momentary pleasure, uncertain in its results, is given up, but only in order to gain in the new way an assured pleasure coming later. But the end psychic impression made by this substitution has been so powerful that it is mirrored in a special religious myth. The doctrine of reward in a future life for the—voluntary or enforced—renunciation of earthly lusts is nothing but a mythical projection of this revolution in the mind. In logical pursuit of this prototype, religions have been able to effect the absolute renunciation of pleasure in this life by means of the promise of compensation in a future life; they have not, however, achieved a conquest of the pleasure-principle this way. It is science which comes nearest to succeeding in this conquest; science, however, also offers intellectual pleasure during its work and promises practical gain at the end.”

“The freeing of an individual, as he grows up, from the authority of his parents is one of the most necessary though one of the most painful results brought about by the course of his development. It is quite essential that that liberation should occur and it may be presumed that it has been to some extent achieved by everyone who has reached a normal state. Indeed, the whole progress of society rests upon the opposition between successive generations. On the other hand, there is a class of neurotics whose condition is recognizably determined by their having failed in this task.”

“The liberty of the individual is no gift of civilization. It was greatest before there was any civilization.”

“No neurotic harbors thoughts of suicide which are not murderous impulses against others redirected upon himself.”

“It goes without saying that a civilization which leaves so large a number of its participants unsatisfied and drives them into revolt neither has nor deserves the prospect of a lasting existence.”

“The time comes when each of us has to give up as illusions the expectations which, in his youth, he pinned upon his fellow-men, and when he may learn how much difficulty and pain has been added to his life by their ill-will.”
