The only thing we have to fear on this planet is man.

Instead of being at the mercy of wild beasts, earthquakes, landslides, and inundations, modern man is battered by the elemental forces of his own psyche. This is the World Power that vastly exceeds all other powers on earth. The Age of Enlightenment, which stripped nature and human institutions of gods, overlooked the God of Terror who dwells in the human soul.

There can be no transforming of darkness into light and of apathy into movement without emotion.

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

Knowing your own darkness is the best method for dealing with the darknesses of other people.

Plato's world of ideas is beautiful.

The sad truth is that man's real life consists of a complex of inexorable opposites - day and night, birth and death, happiness and misery, good and evil. We are not even sure that one will prevail against the other, that good will overcome evil, or joy defeat pain. Life is a battleground. It always has been and always will be; and if it were not so, existence would come to an end.
