“Neurotics complain of their illness, but they make the most of it, and when it comes to taking it away from them they will defend it like a lioness her young.”

“All neurotics, and many others besides, take exception to the fact that 'inter urinas et faeces nascimur.”

“The view is often defended that sciences should be built up on clear and sharply defined basal concepts. In actual fact no science, not even the most exact, begins with such definitions. The true beginning of scientific activity consists rather in describing phenomena and then in proceeding to group, classify and correlate them.”

“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.”

“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.”

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

“When making a decision of minor importance, I have always found it advantageous to consider all the pros and cons. In vital matters, however, such as the choice of a mate or a profession, the decision should come from the unconscious, from somewhere within ourselves. In the important decisions of personal life, we should be governed, I think, by the deep inner needs of our nature.”
