- “It is indeed, an absurd exaggeration to say that we are all mad, just as it is true that we are none of us perfectly healthy. If there were to appear in the world a perfectly sane man, he would certainly be locked up. The terrible simplicity with which he would walk over our minor morbidities, or sulky vanities and malicious self-righteousness; the elephantine innocence with which he would ignore our fictions or civilization—these would make him a thing more desolating and inscrutable than a thunderbolt or a beast of prey. It may be that the great prophets who appeared to mankind as mad were in reality raving with an impotent sanity."
- "Genius ought to be centric. It ought to be the core of the cosmos, not on the revolving edges. People seem to think it a compliment to accuse one of being an outsider, and to talk about the eccentricities of genius. What would they think, if I said I only wish to God I had the centricities of genius."
