History, insofar as it accustoms human beings to comprehend the whole of the past and to hasten forward with its conclusions into the far future, conceals the boundaries of birth and death, which enclose the life of the human being so narrowly and oppressively, and with a kind of optical illusion, expands his short existence into endless space, leading the individual imperceptibly over into humanity.
Friedrich SchillerThere are evil spirits who suddenly fix their abode in man's unguarded breast, causing us to commit devilish deeds, and then, hurrying back to their native hell, leave behind the stings of remorse in the poisoned bosom.
Friedrich Schiller
