The universe indeterministic?Yet in another part of Zarathustra Nietzsche claims that when we look long-term enough and from the bird's-eye perspective of supreme powers big enough, a chance is unimportant, because it is subject to and step-by-step softened and arranged by natural laws and necessities which constitute the order of the world and evolution:
To Nietzsche everything in this world is an expression of will to power. To exist is to represent will to power, to cause influence (compare similar views of Protagoras' disciples in Plato's Theaetetus). One can cause influence only on something that exists. Therefore (through induction) an act changes everything from that moment onwards. If one thing was otherwise, everything would have to be otherwise (and generally also backwards).This belief, perhaps not 100% deterministic, is explicitly expressed in Twilight of the Idols, "Morality as Anti-Nature", 6, tr. W. Kaufmann & R.J. Hollingdale: "To say to him, «Change yourself!» is to demand that everything be changed, even retroactively." Contrary to Chesterton's views, this general rule is not precluded even by absolute chances: they of course change the course of the world too, but still: if one thing was set otherwise, everything would have to be otherwise.
Several scholars have argued that Nietzsche wasn't a determinist in his views of the universe.B. Leiter, Nietzsche on morality (2nd edition), Routledge 2015, p. 66. https://books.google.com/books?id=hBDEBAAAQBAJ&pg=PA66&f=false Online text here
In Zarathustra, absolute randomness (maybe not as the essence of reality, but as a part thereof) can be thought of, yes, perhaps it even exists:
