“In matters of sexuality we are at present, every one of us, ill or well, nothing but hypocrites.”

“The behavior of a human being in sexual matters is often a prototype for the whole of his other modes of reaction in life.”

“And it is only after seeing man as his unconscious, revealed by his dreams, presents him to us that we shall understand him fully. For as Freud said to Putnam: "We are what we are because we have been what we have been.”

“According to the prevailing view human sexual life consists essentially in an endeavor to bring one's own genitals into contact with those of someone of the opposite sex.”

“Thus we arrive at the singular conclusion that of all the information passed by our cultural assets it is precisely the elements which might be of the greatest importance to us and which have the task of solving the riddles of the universe and of reconciling us to the sufferings of life -- it is precisely those elements that are the least well authenticated of any.”

“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.”

“Analogies, it is true, decide nothing, but they can make one feel more at home.”
