People should be more like animals . . . they should be more intuitive; they should not be too conscious of what they do while they do it.

If I were to remain silent, I'd be guilty of complicity.

I am not a positivist. Positivism states that what cannot be observed does not exist. This conception is scientifically indefensible, for it is impossible to make valid affirmations of what people 'can' or 'cannot' observe. One would have to say 'only what we observe exists,' which is obviously false.

To raise new questions, new possibilities, to regard old problems from a new angle, requires creative imagination and marks real advance in science.

A problem defined, is a problem half solved.

A conviction akin to religious feeling of the rationality or intelligibility of the world lies behind all scientific work of a high order.

It is this mythical, or rather symbolic, content of the religious traditions which is likely to come into conflict with science. This occurs whenever this religious stock of ideas contains dogmatically fixed statements on subjects which belong in the domain of science.
