An ontological theorist generally begins his discussion with a preconceived notion of what kind of thing an object will turn out to be. Instead, we will here begin with a Thomassonian approach to the ontology of mathematics. First, let us consider what happens when we rst come to determine a mathematical proposition (which I will use synonymously with
'mathematical entitty'). A mathematician does not feel as though he creates mathematical theories. Pythagoras can hardly be thought to have created the claim that a2 + b2 = c2. It becomes clear that a mathematical proposition is a discovered one; that is, we would hardly nd ourselves contending that Pythagoras created his famous theorem. Regardless of who discovers it, the same mathematical …show more content…

Already we have found that an ontology must, at the very least, account for the fact that mathematic is about tangible, physical things (even if those things turn out to be merely relations of things). The ctionalist claim seems to address mathematics as a purely linguistic issue, though what mathematics describes is certainly not.
We must then ask whether what math describes is actually there. It seems that the language of mathematics, expressions such as a2 + b2 = c2, are purely constructed terms in the same way that we would be willing to say English is. Perhaps, then, we might lean towards an intuitionist approach like that describes in J.R. Brown [2]. An intuitionist, or constructivist, suggests that mathematical concepts|that is, in our terms, relationships| have no existence until a human mind creates them [4]. However, in suggesting this, we run into some major problems. First, intuitionism looks as though it's going to reject some claims of already accepted mathematics and logic; namely, claims such as the Law of the
Excluded Middle. This is because an intuitionist holds that only until a claim is proven or disprove does it have a true or false truth-value. Propositions such as Goldbach's
