“I came to consider the instinct as nothing more than the "motor aspect of pleasure."”

“I can imagine no greater catastrophe than if I were mistaken, and the theory were correct that what I consider secondary instincts or drives are actually primary instincts! Because in that case the emotional plague would rest upon the support of a natural law while its archenemies, truth and sociality, would be relying upon unfounded ethics. Until now both lies and truth have taken recourse to ethics. But only lies have profited because they were able to appear under the guise of truth. Under these circumstances, egoism, theft, petty selfishness, slander, etc., would be the natural rule. (26.july.1943)”

“The pleasure of living and the pleasure of the orgasm are identical. Extreme orgasm anxiety forms the basis of the general fear of life.”

“You'll have a good, secure life when being alive means more to you than security, love more than money, your freedom more than public or partisan opinion, when the mood of Beethoven's or Bach's music becomes the mood of your whole life … when your thinking is in harmony, and no longer in conflict, with your feelings … when you let yourself be guided by the thoughts of great sages and no longer by the crimes of great warriors … when you pay the men and women who teach your children better than the politicians; when truths inspire you and empty formulas repel you; when you communicate with your fellow workers in foreign countries directly, and no longer through diplomats...”

“Man's right to know, to learn, to inquire, to make bona fide errors, to investigate human emotions must, by all means, be safe, if the word "freedom" should ever be more than an empty political slogan.”

“The "stiff, dead, retracted pelvis" is one of man's most frequent vegetative disturbances. It is responsible for lumbago as well as for hemorrhoidal disturbances. Elsewhere, we shall demonstrate an important connection between these disturbances and genital cancer in women, which is so common.Thus, the "deadning of the pelvis" has the same function as the deadening of the abdomen, i.e., to avoid feelings, particularly those of pleasure and anxiety.”

“I consider it an error in scientific communication that, most of the time, merely the polished and flawless results of natural research are displayed, as in an art show. And exhibit of the finished product alone has many drawbacks and dangers for both its creator and its users. The creator of the product will be only too ready to demonstrate perfection and flawlessness while concealing gaps, uncertainties and discordant contradictions of his insight into nature. He thus belittles the meaning of the real process of natural research. The user of the product will not appreciate the rigorous demands made on the natural scientist when the latter has to reveal and describe the secrets of nature in a practical way. He will never learn to think for himself and to cope by himself. Very few drivers have an accurate idea of the sum of human efforts, of the complicated thought processes and operations needed for manufacturing an automobile. Our world would be better off is the beneficiaries of work knew more about the process of work and the existence of the workers, if they did not pluck so thoughtlessly the fruits of labor performed by others.”
