Whoever thou mayest be, beloved stranger, whom I meet here for the first time, avail thyself of this happy hour and of the stillness around us, and above us, and let me tell thee something of the thought which has suddenly risen before me like a star which would fain shed down its rays upon thee and every one, as befits the nature of light— 25 The world of energy suffers no diminution: otherwise with eternal time it would have grown weak and finally have perished altogether. The world of energy suffers no stationary state, otherwise this would already have been reached, and the clock of the universe would be at a standstill. The world of energy does not therefore reach a state of equilibrium; for no instant in its career has it had rest; its energy and its movement have been the same for all time. Whatever state this world could have reached must ere now have been attained, and not only once but an incalculable number of times. This applies to this very moment It has already been here once before, and several times, and will recur in the same way, with all forces distributed as they are to-day: and the same holds good of the moment of time which bore the present and of that which shall be the child of the present. Fellow-man! Your whole life, like a sandglass, will always be reversed and will ever run out again,—a long minute of time will elapse until all those conditions out of which you were evolved return in the wheel of the cosmic process. And then you will find every pain and every pleasure, every friend and every enemy, every hope and every error, every blade of grass and every ray of sunshine once more, and the whole fabric of things that makes up your life. This ring in which you are but a grain will glitter afresh for ever. And in every one of these cycles of human life there will be one hour where for the first time one man, and then many, will perceive the mighty thought of the eternal recurrence of all things:—and for mankind this is always the hour of Noon. 2. THE EFFECTS OF THE DOCTRINE UPON MANKIND 26 How can we give weight to our inner life without making it evil and fanatical towards people who think otherwise. Religious belief is declining and man is beginning to regard himself as ephemeral and unessential, a point of view which is making him weak; he does not exercise so much effort in striving or enduring. What he wants is momentary enjoyment He would make things light for himself,—and a good deal of his spirit gets squandered in this endeavour. 27
