"Sometimes the mind, for reasons we don't necessarily understand, just decides to go to the store for a quart of milk." - Diane Frolov and Andrew Schneider, Northern Exposure, Three Doctors, 1993

"It is no measure of health to be well adjusted to a profoundly sick society." - Krishnamurti

"A man who is 'of sound mind' is one who keeps the inner madman under lock and key." - Paul Valéry, Mauvaises pensées et autres, 1942

"I became insane, with long intervals of horrible sanity." - Edgar Allan Poe (1809-1849)

"One is healthy when one can laugh at the earnestness and zeal with which one has been hypnotized by any single detail of one's life." - Friedrich Nietzsche
