The pathetic thing that grows out of this condition is called faith: in other words, closing one's eyes upon one's self once for all, to avoid suffering the sight of incurable falsehood. People erect a concept of morality, of virtue, of holiness upon this false view of all things; they ground good conscience upon faulty vision; they argue that no other sort of vision has value any more, once they have made theirs sacrosanct with the names of "God," "salvation" and "eternity." I unearth this theological instinct in all directions: it is the most widespread and the most subterranean form of falsehood to be found on earth.

Friedrich Nietzsche
