“Now the twitching stops. Now you are still. We are through with physiology and theology, physics begins.”
—Alfred Döblin (1878–1957)
“If church prelates, past or present, had even an inkling of physiology they’d realise that what they term this inner ugliness creates and nourishes the hearing ear, the seeing eye, the active mind, and energetic body of man and woman, in the same way that dirt and dung at the roots give the plant its delicate leaves and the full-blown rose.”
—Sean O’Casey (1884–1964)
“The human mind is indeed a cave swarming with strange forms of life, most of them unconscious and unilluminated. Unless we can understand something as to how the motives that issue from this obscurity are generated, we can hardly hope to foresee or control them.”
—Charles Horton Cooley (1864–1929)
