I have researched and taught philosophy at the City University of New York (including the Graduate Center) and at Universidad Nacional Autónoma de México (IIF), where I was a postdoctoral researcher. I am currently a Visiting Professor at Wesleyan University while working on a book about the great Alonzo Church for Oxford University Press. Other than that, I use logic (and a bit of set theory) to study representation (roughly, how language represents objective reality). In particular, I study mathematical representation; here my goal is to describe a philosophy of language suitable for mathematical language, in order to better understand both the “foundations” of mathematics and how we acquire mathematical knowledge. I also use type theory (and a little set theory) to study representational entities – propositions. My work on all this draws on insights from the analytic tradition of Frege, Russell, early Wittgenstein, Church, and Kripke. In addition to studying objective representational entities, I’m also interested in how the cognitive abilities to grasp them entered our species and our culture. These matters are connected, since the correct logic of representation –the correct “intensional logic”– is the proper background logic for theorizing about representation in cognitive psychology.
