1. if there is no god, there is no creation orbeginning, and, therefore, time is infinite
2. the number of things and arrangements of things is finite
3. therefore, events must repeat themselves, infinitely - hence, eternalrecurrence
Time is infinite, but space and matter are finite, so they can mix and combine in a finite number of permutations, therefore, there must be permutations that repeatcontinuously throughout the time
=> we must have lived this life lots of time in the past and will live it in the future
Everything goes on and on in a circle
The question ineach and every thing, "Do you desire this once more and innumerable times more?"' will either crush you or lead you to transform your life - what if one were to live life as if itwere to recur eternally
What is the meaning of MY life?
How differently would one live if one did, in fact, face each day as though one would have to live it over innumerabletimes?
What different choices would one make?
Would one really agree to sentence oneself to an eternal life of boredom and disappointment when, by making other choices, onecould live a life of real meaning and excitement and vitality?
The Theory of Eternal Recurrence, which Nietzsche himself thought people would be horrified at the prospect of,provides one with a moment's pause in life in which to reflect on exactly how one is spending one's time on earth and how one values that time.
The meaning of life then becomesliving life itself to the fullest, experiencing all it has to offer; whether one then gets to live it over again eternally isn't really the point -- the point is to live it now.
