forum for week of Nov 7: kinds of apriori beliefs

I think that the previous poster hit on a very important point, regarding the placement of predicate logic within the framework of a priori beliefs. I would argue, however, that predicate logic is an example that falls under both categories of math and meanings (leaning perhaps more towards math, but that is a separate issue). I don't think that there are any a priori beliefs outside the realms of mathematics and definitions (which, incidentally, seem to overlap a lot), because anything we could justify independent of experience, or before evidence, would need to be thought of within a framework of logical rules, and as the previous poster has already posited, it seems as though predicate logic itself is a combination of mathematical rules and definitions. Even language, when really boiled down and stripped bare, seems to be a manifestation of some sort of syntactic structure or another, which really is no different from mathematics (for instance, consider the roles parsing trees play in both the study of language and mathematics). In short, it seems to me that a priori beliefs outside of mathematics and definitions are difficult (perhaps impossible) to really find because we are structured, in the absence of evidence, to think in terms of mathematics and definitions, and in combinations of the two, the primary combination being predicate logic.
