" A boundless mass of human Being, flowing in a stream without banks; up-stream, a dark past wherein our time-sense loses all powers of definition and restless or uneasy fancy conjures up geological periods to hide away an eternally unsolvable riddle; down-stream, a future even so dark and timeless –– such is the groundwork of the Faustian picture of human history. "

― Oswald Spengler , The Decline of the West
