That is the case for inductive inference, but here I was alluding to the induction axioms, which are used only in deduction. The induction axioms on the numbers is P(0) & [For all n (P(n) -> P(s(n)))] ->. For all n P(n). Or, for the combinators, it is P(K) & P(S) & [For all x y ((P(x) & P(y)) -> P(xy)) -> For all x P(x) I do think that inductive inference has deep relation with mathematical induction, though. But that is beyond the cope of this post. > if Everett is right (and my hunch is he is) for some universes that would be > true, but such a chaotic universe would not have structures capable of > producing thought or consciousness.

But when used in physics, this type of inductive inference assume not only a reality, but a “brain-mind” identity, which is not consistent with the mechanist hypothesis.
