In my books and papers, I focus on questions that figure both in ancient and contemporary discussions: What are values? What kind of values are knowledge and truth? What is the role of imagination in decision making? What does it mean to want one’s life to go well? When I’m not in NYC, I’m traveling with photographer and artist Jens Haas. On the Road has become an art project and a philosophical diary. Movies and Morals, in collaboration with H8URS, is a growing series of video commentary on philosophy and art in contemporary film and television shows.
In my recent Desiring the Good: Ancient Proposals and Contemporary Theory (OUP, 2017), I aim to show in which sense it may be true that human beings are “the measure” such that this is not a relativist proposal, but an insight about the nature of ethics. Several follow-up projects in the philosophy of action develop this framework further, in particular with respect to the relation between ethics and psychology. In Imagination and Agency, I aim to clarify the Aristotelian dictum that deliberation is about the possible, and what it means that some decision is right. I co-authored three papers with Jens Haas, “Incomplete Ignorance” (2020), “Ignorance and Investigation” (2015), and “Love and Hatred” (2018). In a new volume, Epistemology After Sextus Empiricus (OUP, 2020), co-edited with Justin Vlasits, I return to my long-term interest in skepticism, and I’m finalizing a set of related papers for a monograph, tentatively entitled The Original Stoics.
I’m an editor of Nous and serve on the editorial boards of the Journal of Philosophy, Apeiron, and Rhizomata, and as Associate Editor for philosophy of language, epistemology, and logic of Dialogoi: Ancient Philosophy Today.
