“What if some day or night a demon were to steal after you into your loneliest loneliness and say to you: 'This life as you now live it and have lived it, you will have to live once more and innumerable times more; and there will be nothing new in it, but every painand every joy and every thought and sigh and everything unutterably small or great in your life will have to return to you, all in the same succession and sequence ... 'Would you not throw yourself down and gnash your teeth and curse the demon whospoke thus? Or have you once experienced a tremendous moment when you would haveanswered him, 'You are a god and never have I heard anything more divine.' ...The question in each and every thing, 'Do you desire this once more and innumerabletimes more?' would lie upon your actions as the greatest weight.”
