Thank you - I had not thought about a deterministic universe without causation.hackenslash said:The foregoing doesn't demonstrate anything of the sort, even in the absence of such an entity. You could be living in an entirely deterministic universe (you aren't, as can readily be demonstrated) and the forgoing demonstration would be unchanged. All you've demonstrated is that you seem to have free will, but that could be entirely illusory and you'd never be any the wiser.
If any omniscient entity did exist, then the universe would be deterministic, and any choice you thought you had would be merely the appearance of choice, not the actuality of it.
On the latter, what if the omniscient entity was not perturbed by "knowing" and allowed for unrestricted probabilities to be realised. That is, infinite landscapes of infinite probability of objects, entities and events: Free will would be equally real and illusory.
