Academic Interests: Logic / Semiotics / Metaphysics / Philosophy of Nature / Mimetic Theory

I wrote my M.A. thesis on Studies in Aristotle's Physics and my Ph.D. dissertation on René Girard's hominization hypothesis. My book of Hesiod’s poetry, Hesiod: Theogony / Works and Days, has been published by Talonbooks. I am the managing editor of The American Journal of Semiotics and a Fellow of the Adler-Aquinas Institute. My current research studies the relationship to semiotics of TFL (Traditional Formal Logic / Term Functor Logic): "While post-Fregean logicians tend to ignore or even denigrate the traditional logic of Aristotle and the Scholastics, new work in recent years has shown the viability of a renewed, extended, and strengthened logic of terms that shares fundamental features of the old syllogistic. A number of logicians, following the lead of Fred Sommers, have built just such a term logic. It is a system of formal logic that not only matches the expressive and inferential powers of today’s standard logic, but surpasses it and is far simpler and more natural," observes George Englebretsen. As part of this project, I am investigating the extensive tradition of medieval logic, especially the work of John of St. Thomas in his Cursus Philosophicus. In metaphysics and natural theology, I am investigating how TFL formalizations of Aquinas' Five Ways can advance our understanding of metaphysics, mimetic theory, and the philosophy of nature.
