nietzschean

What if a demon were to creep after you one day or night, in your loneliest loneness, and say: "This life which you live and have lived, must be lived again by you, and innumerable times more. And mere will be nothing new in it, but every pain and every joy and every thought and every sigh— everything unspeakably small and great in your life—must come again to you, and in the same sequence and series__" Would you not throw your self down and curse the demon who spoke to you thus? Or have you once experienced a tremendous moment, in which you would answer him: "Thou art a god, and never have I heard anything more divine!"
