Welcome to my webpage! I’m a Professor in the Department of Philosophy at Western Michigan University. My most recent research is in epistemology and, in particular, the debate concerning knowledge closure and related issues (that is, the rest of epistemology). I’ve recently published Against Knowledge Closure (Cambridge UP) on the topic, wherein I argue that closure is false, that just about any epistemologist should agree regardless of their particular views (aside from their commitment to closure, if they are so committed), and that its failing is very good news when it comes to dealing with various epistemological conundrums (skepticism, easy knowledge, bootstrapping, and many others). Before turning into an epistemologist, I was interested in the realism debate(s) and, in particular, whether an empiricist should be (or needs to be) an anti-realist in the philosophy of science (the answer: no). And before that, I explored the history of analytic philosophy, with special attention to the views of, and disagreements between, Rudolf Carnap and W. V. Quine on the status of ontological issues. My colleagues Timothy Mcgrew and Fritz Allhoff and I have also published Philosophy of Science: An Historical Anthology, an anthology of historical writings from antiquity to the 20th century by scientists and philosophers of science, with extensive commentary.
