“The conscience of the world is so guilty that it always assumes that people who investigate heresies must be heretics; just as if a doctor who studies leprosy must be a leper. Indeed, it is only recently that science has been allowed to study anything without reproach.”
—Aleister Crowley (1875–1947)
“When a doctor does go wrong he is the first of criminals. He has nerve and he has knowledge.”
