The dream arises from a part of the mind unknown to us, but none the less important, and is concerned with the desires for the approaching day.

Life is teleology par excellence; it is the intrinsic striving towards a goal, and the living organism is a system of directed aims which seek to fulfill themselves.

There is a thinking in primordial images, in symbols which are older than the historical man, which are inborn in him from the earliest times, eternally living, outlasting all generations, still make up the groundwork of the human psyche. It is only possible to live the fullest life when we are in harmony with these symbols; wisdom is a return to them.

A man who has not passed through the inferno of his passions has never overcome them.

Who looks outside, dreams; who looks inside, awakes.

Knowledge rests not upon truth alone, but upon error also.
