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 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.
My most recent book is entitled Desiring the Good: Ancient Proposals and Contemporary Theory, Oxford (2017). The book engages with Protagorean relativism, Aristotle’s Nicomachean Ethics, and Plato’s Euthyphro, Symposium, and Philebus. 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. I’m interested in the nature of ethics more generally, what (if anything) morality is, and the metaphysics of value. A project on Imagination and Agency is funded by the Templeton Foundation and part of a larger project on Happiness and Wellbeing. I aim to clarify the Aristotelian dictum that deliberation is about the possible, the range of cognitive activities involved in making the right decision, and what it means to think that some decision is right.
In normative epistemology I’m interested in bringing ancient and contemporary epistemology into conversation, in particular with a view to proposals and arguments found in Plato and ancient skepticism. Currently I work on the history of the JTB account of knowledge and on the nature of ignorance. A co-authored paper with Jens Haas, entitled “Ignorance and Investigation,” was published in (2015).
