One is forced to speak not of what is held in common between the cultures, but what is held in common between the myths, and that in its simplest archetypal forms.

The greatest and most important problems of life are all fundamentally insoluble. They can never be solved but only outgrown.

I use [Heraclitus' discovery of] enantiodromia for the emergence of the unconscious opposite in the course of time. This characteristic phenomenon practically always occurs when an extreme, onesided tendency dominates conscious life; in time an equally powerful counterposition is built up, which first inhibits the conscious performance and subsequently breaks through the conscious control.

The facts of nature cannot in the long run be violated. Penetrating and seeping through everything like water, they will undermine any system that fails to take account of them, and sooner or later they will bring about its downfall. But an authority wise enough in its statesmanship to give sufficient free play to nature - of which spirit is a part - need fear no premature decline.

The images of the unconscious place a great responsibility upon a man. Failure to understand them, or a shirking of ethical responsibility, deprives him of his wholeness and imposes a painful fragmentariness on his life.
