I'm a Professor of Philosophy with 15 years of experience designing and teaching Philosophy and Religion courses for students and lifelong learners. I also produce philosophy videos in YouTube, provide workshops for institutions and organizations, and give talks, interviews, and presentations for more general audiences.
I'm the author of one book (so far) and dozens of articles, book chapters, and encyclopedia entries. I also translate works from French and Latin, and am a longstanding member of the Thomas Aquinas Translation Project.
My work spans the History of Philosophy, and some of my areas of particular focus are Ethics, Political Theory, Philosophy of Religion, and Metaphysics. I've published or presented on figures ranging from ancients like Plato and Aristotle, through medievals like Anselm and Thomas Aquinas, to moderns like Thomas Hobbes and G.W.F. Hegel, to contemporary thinkers like Jacques Lacan, Dietrich Von Hildebrand, and Alasdair MacIntyre.
As a speaker, author, educator, and consultant, I bring philosophy into practice, making complex classic philosophical ideas accessible for a wide audience of professionals, students, and life-long learners.
I am excited to share my latest course on Curious, Reviewing "The Wall" by Jean Paul Sartre!
