Determinism, Free Will and Paradox

[Mudhammam]

Commenting on Greene's text, I don't think he's saying anything particularly complicated - we can in principle say something about the probability of arbitrary future events if we know the wave function of the universe at any given moment in time exactly. This may be called quantum determinism, but it's a very weak thing, don't you think.

What I notice is that he likes to assigns a degree of realism to the wave function (as something which is real, one could in principle know, and which persists indefinitely, is all- encompassing, only governed by the schroedinger equation). This, to me, is already very close to a full many worlds interpretation. In fact, I think it is the MWI with him not admitying it.Others would not go as far as he does here.

Yeah, I would agree, it's a "weak" determinism in comparison to macroscopic causality. So, to what extent do the probabilistic outcomes of wave-functions affect anything in our lives or the Universe at large, other than the implication that when the Universe was really really really small and really really really young, "all bets were off" with regards to the forms that matter would eventually take?
