"What if a demon crept after you one day or night in your loneliest solitude and said to you: 'This life, as you live it now and have lived it, you will have to live again and again, times without number, and there will be nothing new in it, but every pain and every joy and every thought and every sigh and all the unspeakably small and great in your life must return to you, and everything in the same series and sequences - and in the same way this spider and this moonlight among the trees, and in the same way this moment and I myself. The eternal hourglass will again and again be turned and you with it, dust of the dust!' Would you throw yourself down and gnash your teeth and curse that demon? Or would you answer, 'Never have I heard anything more divine?'"
- Friedrich Neitzsche
