Everyone can afford to give away a smile.

The debt we owe to the play of imagination is incalculable.

Art is a kind of innate drive that seizes a human being and makes him its instrument. The artist is not a person endowed with free will who seeks his own ends, but one who allows art to realize its purpose through him. As a human being he may have moods and a will and personal aims, but as an artist he is "man" in a higher sense— he is "collective man"— one who carries and shapes the unconscious, psychic forms of mankind.

Space flights are merely an escape, a fleeing away from oneself, because it is easier to go to Mars or to the moon than it is to penetrate one's own being.

Every civilized human being, whatever his conscious development, is still an archaic man at the deeper levels of his psyche.

I readily admit that I have such a great respect for what happens in the human soul that I would be afraid of disturbing and distorting the silent operation of nature by clumsy interference.
