“One constructs for oneself a satisfactory system only when one is ignorant of the characteristics of the phenomena to be explained.”

“That one must either explain life to oneself so that it does not seem to be an evil mockery by some sort of devil, or one must shoot oneself.”

“Being cared for when one is dead is less satisfactory than being cared for when one is alive.”

“The sciences do not try to explain, they hardly even try to interpret, they mainly make models. By a model is meant a mathematical construct which, with the addition of certain verbal interpretations, describes observed phenomena. The justification of such a mathematical construct is solely and precisely that it is expected to work - that is correctly to describe phenomena from a reasonably wide area. Furthermore, it must satisfy certain esthetic criteria - that is, in relation to how much it describes, it must be rather simple.”

“One could only damage oneself through the harm one did to others. One could never get directly at oneself.”

“The main condition for the achievement of love is the overcoming of one's narcissism. The narcissistic orientation is one in which one experiences as real only that which exists within oneself, while the phenomena in the outside world have no reality in themselves, but are experienced only from the viewpoint of their being useful or dangerous to one. The opposite pole to narcissism is objectivity; it is the faculty to see other people and things as they are, objectively, and to be able to separate this objective picture from a picture which is formed by one's desires and fears.”
