β€œIn endless space countless luminous spheres, round each of which some dozen smaller illuminated ones revolve, hot at the core and covered over with a hard cold crust; on this crust a mouldy film has produced living and knowing beings: this is empirical truth, the real, the world. Yet for a being who thinks, it is a precarious position to stand on one of those numberless spheres freely floating in boundless space, without knowing whence or whither, and to be only one of innumerable similar beings at that throng, press, and toil, restlessly and rapidly arising and passing away in beginningless and endless time. Here there is nothing permanent but matter alone, and the recurrence of the same varied organic forms by means of certain ways and channels that inevitably exist as they do. All that empirical science can teach is only the more precise nature and rule of these events.”

~ Arthur Schopenhauer – The World as Will and Representation, Vol. II, Chapter 1.
