If faith cannot be reconciled with rational thinking, it has to be eliminated as an anachronistic remnant of earlier stages of culture and replaced by science dealing with facts and theories which are intelligible and can be validated.
Our social pattern is such that the successful man is not supposed to be afraid or bored or lonely. He must find this world the best of all worlds; in order to have the best chance for promotion he must repress fear as well as doubt, depression, boredom, or hopelessness.
A sane society is that which corresponds to the needs of man — not necessarily to what he feels to be his needs, because even the most pathological aims can be felt subjectively as that which the person wants most; but to what his needs are objectively, as they can be ascertained by the study of man. It is our first task then, to ascertain what is the nature of man, and what are the needs which stem from this nature.
It is naively assumed that the fact that the majority of people share certain ideas or feelings proves the validity of these ideas and feelings. Nothing is further from the truth. Consensual validation as such has no bearing whatsoever on reason or mental health. Just as there is a folie à deux there is a folie à millions. The fact that millions of people share the same vices does not make these vices virtues, the fact that they share so many errors does not make the errors to be truths, and the fact that millions of people share the same mental pathology does not make these people sane.
Man is born as a freak of nature, being within nature and yet transcending it. He has to find principles of action and decision making which replace the principles of instincts. he has to have a frame of orientation which permits him to organize a consistent picture of the world as a condition for consistent actions. He has to fight not only against the dangers of dying, starving, and being hurt, but also against another anger which is specifically human: that of becoming insane. In other words, he has to protect himself not only against the danger of losing his life but also against the danger of losing his mind.
