William James

Man, biologically considered, and whatever else he may be into the bargain, is the most formidable of all the beasts of prey, and, indeed, the only one that preys systematically on its own species.

The world is all the richer for having a devil in it, so long as we keep our foot upon his neck.

The first thing to learn in intercourse with others is non-interference with their own peculiar ways of being happy.

Our faith is faith in some one else's faith, and in the greatest matters this is most true.

Men differ from each other in nothing so much as in the way in which they come to perceive.

The world is not a place where we are to be made happy, but where we are to be made useful.

A man's religion is the most important thing about him.

The moment of creative energy is the moment of choice.

The more things a man is interested in, the more opportunities of happiness he has.

The world is still in the making, and awaits our co-operation.
