“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 art of living has no history: it does not evolve: the pleasure which vanishes vanishes for good, there is no substitute for it. Other pleasures come, which replace nothing. No progress in pleasures, nothing but mutations.”

“I was still young and the whole world of beauty was opening before me, my own officious obstructions were often swept aside and, startled into self-forgetfulness, I again tasted Joy. ... One thing, however, I learned, which has since saved me from many popular confusions of mind. I came to know by experience that it is not a disguise of sexual desire. ... I repeatedly followed that path - to the end. And at the end one found pleasure; which immediately resulted in the discovery that pleasure (whether that pleasure or any other) was not what you had been looking for. No moral question was involved; I was at this time as nearly nonmoral on that subject as a human creature can be. The frustration did not consist in finding a "lower" pleasure instead of a "higher." It was the irrelevance of the conclusion that marred it. ... You might as well offer a mutton chop to a man who is dying of thirst as offer sexual pleasure to the desire I am speaking of. ... Joy is not a substitute for sex; sex is very often a substitute for Joy. I sometimes wonder whether all pleasures are not substitutes for Joy.”

“Sorrow, terror, anguish, despair itself are often the chosen expressions of an approximation to the highest good. Our sympathy in tragic fiction depends on this principle; tragedy delights by affording a shadow of the pleasure which exists in pain. This is the source also of the melancholy which is inseparable from the sweetest melody. The pleasure that is in sorrow is sweeter than the pleasure of pleasure itself.”

“I have absolutely no pleasure in the stimulants in which I sometimes so madly indulge. It has not been in the pursuit of pleasure that I have periled life and reputation and reason. It has been the desperate attempt to escape from torturing memories, from a sense of insupportable loneliness and a dread of some strange impending doom.”

“Later she remembered all the hours of the afternoon as happy -- one of those uneventful times that seem at the moment only a link between past and future pleasure, but turn out to have been the pleasure itself.”
