" FANATICISM is, to superstition, what delirium is to fever, and fury to anger : he who has ecstasies and visions, who takes dreams for realities, and imaginations for prophecies, is an enthusiast ; and he, who sticks not at supporting his folly by murder, is a fanatic. "

― Voltaire , A Philosophical Dictionary, Volume 3 (of 10) From "The Works of Voltaire - A Contemporary Version"
