As is true of many contemporary philosophers, I have wide ranging interests. I mainly focus on metanormative issues concerning norms, reasons, value, and virtue, across ethics and epistemology. I am also interested in exploring these broad issues in a way that includes aesthetics. I have a more specific interest in the aesthetics and ethics of photography.
A number of my published papers are concerned with defending a particular theory concerning the nature of normative reasons (reasons to do things, believe things, and so on), but I have also published articles and book chapters on moral knowledge, virtue and ethical theory, moral skepticism, the history of moral metaphysics, and Confucian ethics.
My book follows on from the earlier work on reasons, but is broader in scope, as it is about the relationship of normative ethical theory to ordinary virtue. The interest in reasons has led to the editing of an Oxford Handbook, while my general interest in ethics drives a long running seminar series.
