The basic arche is 'wiil to power';this can only denote Becoming;there is nothing static in the universe.The ability to think the world is flat,or that the earth is the centre of the universe is of the same ilk as morality.If we really knew ONLY of the constant fluxions of the universe,we would not be able to survive;we NEED to posit a subject,a stability etc.It is when man becomes ever more aware of the meaninglessness and instability of the universe that he has to use extraordinary will power to 'stamp Being on Becoming'.This world of flux with its chaos and indeterminism does not allow for 'freedom';Man must assert all that he IS because it cannot be any other way.It is his tragic heroism which sees him exerting his existence and strength of will against an indifferent universe.Nietzsche will not take the Schopenhauerian, Buddhistic [and indeed liberal consumer escapism] path of resignation in the face of this terrifying truth of cosmic meaninglessness.The pagan terms of Fate [in Old Norse religion the Norns can be said to represent,'what has become','what is becoming' and 'what is yet to become'],Destiny and Necessity convey an understanding of our modern chaotic universe absent in Semitic Theology etc.
