Rejecting non-constructive proofs is a change in reasoning. I don't think there is such a sharp division between axioms and rules of inference as you imply. I did not imply that. In most system, you can always limit the rules of inference by adding axioms. With enough axioms, and the modus ponens rule, you can derive all the other rules of inference. In particular, quantum logic, intuitionist logic and classical logic can be all formalized with only the modus ponens rules, and with the same rules for the quantifiers, just by suppressing some axioms in the Kleene's presentation of classical logic. You get quantum logic by replacing "p->(q->p)" by (p->q) -> (r->t) -> (p -> q) (limiting the a posteriori-axiom for implicative formula); you get intuitionist logic by abandoning ~~p -> p. Bruno Brent Basically intuitionism reject the idea that there is an independent reality such that A v ~A applies to it. They accept only ~ ~(A V ~A). If we limit reality to sigma_1 truth, like in the comp TOE, there is no genuine difference between intuitionism and platonism.

That everybody --including materialists, empiricists and rationalists--is a Platonist Empiricism is the doctrine that all knowledge is derived from sense experience. Rationalism is the doctrine that reason alone is a source of knowledge and is independent of experience. Materialism is a combination of both philosophies. These may sound like completely diffierent doctrines, but my point here is that all of these pursuits ultimately rely on intuition. They afre both subbranches of intjuitionism. Why ? Concerning rationalism, even deductive logic requires intuition to arrive at a conclusilon. Concering empiricism, it is fairly obvious to see that experience alone cannot provide us any conclusion. If you dpoubt that, consider Peirce's three categories, in which Secondness is the category of intuion, leading us from an experience to a fact. So Penrose's recent excursion into Platonism should be taken more seriously, for ultimately his criticizers, the empiricists and the rationalists, are both Platonists.
