A man who has not passed through the inferno of his passions has never overcome them. As far as we can discern, the sole purpose of human existence is to kindle a light in the darkness of mere being. Everything that irritates us about others can lead us to an understanding of ourselves.

Only in our creative acts do we step forth into the light and see ourselves whole and complete.

Whenever there is a reaching down into innermost experience, into the nucleus of personality, most people are overcome by fear and many run away. . . The risk of inner experience, the adventure of the spirit, is in any case alien to most human beings. The possibility that such experience might have psychic reality is anathema to them.

The symbol in the dream has more the value of a parable: it does not conceal, it teaches.

Our intellect has created a new world that dominates nature, and has populated it with monstrous machines.

It is in applied psychology, if anywhere, that today we should be modest and grant validity to a number of apparently contradictory opinions; for we are still far from having anything like a thorough knowledge of the human psyche, that most challenging field of scientific enquiry. For the present we have merely more or less plausible opinions that defy reconciliation.

Free will is the ability to do gladly that which I must do.
