Synchronistic phenomena prove the simultaneous occurrence of meaningful equivalences in heterogenous, causally unrelated processes; in other words, they prove that a content perceived by an observer can, at the same time, be represented by an outside event, without any causal connection. From this it follows either that the psyche cannot be localized in time, or that space is relative to the psyche.

We do not know whether Hitler is going to found a new Islam. He is already on the way; he is like Muhammad.

Great talents are the most lovely and often the most dangerous fruits on the tree of humanity. They hang upon the most slender twigs that are easily snapped off.

The Shadow is a moral problem that challenges the whole ego-personality, for no one can become conscious of the shadow without considerable moral effort. To become conscious of it involves recognizing the dark aspects of the personality as present and real.

Indeed, self-knowledge as a psychotherapuetic measure frequently requires much painstaking work extending over a long period of time.

I believe that history is capable of anything. There exists no folly that men have not tried out.
