> Well logic is a sub-category of philosophy, not mathematics.

I disagree! (I would probably say something like that logic, in its informal mathematical meaning (i.e., the meaning that would be given it by a mathematician who is not a logician), lives at the intersection at least of all the sciences.) Nonetheless, it's probably more a matter of terminology, if not even just of my ignorance of the proper domain of philosophy, than of substantive disagreement.
