“Man was, and is, too shallow and cowardly to endure the fact of the mortality of everything living. He wraps it up in rose-coloured progress-optimism, he heaps upon it the flowers of literature, he crawls behind the shelter of ideals so as not to see anything. But impermanence, the birth and the passing, is the form of all that is actual -- from the stars, whose destiny is for us incalculable, right down to the ephemeral concourses on our planet. The life of the individual -- whether this be animal or plant or man -- is as perishable as that of peoples of Cultures. Every creation is foredoomed to decay, every thought, every discovery, every deed to oblivion. Here, there, and everywhere we are sensible of grandly fated courses of history that have vanished. Ruins of the "have-been" works of dead Cultures lie all about us. The hybris of Prometheus, who thrust his hand into the heavens in order to make the divine powers subject to man, carries with it his fall. What, then, becomes of the chatter about "undying achievements"?”
