His teaching and research interests are in moral, political, and legal philosophy, in both the Anglophone and Continental European traditions, and the law of evidence. His books include Objectivity in Law and Morals (Cambridge, 2001) (editor), The Future for Philosophy (Oxford, 2004), Naturalizing Jurisprudence (Oxford, 2007), Why Tolerate Religion? (Princeton, 2013), and Nietzsche on Morality (Routledge, 2nd edition, 2015). His recent articles have appeared in Oxford Journal of Legal Studies, Virginia Law Review, University of Pennsylvania Law Review, Criminal Law & Philosophy, and Oxford Studies in Metaethics. He is presently working on projects in moral psychology and meta-ethics (often in relation to Nietzsche), on realism as a theme in political and legal theory, on meta-ethical and metaphysical questions in general jurisprudence, and on philosophical issues about free speech, in both the liberal and Marxian traditions. His work has been translated into Spanish, French, Italian, Chinese, Russian, Portugese, Hebrew, Polish, Slovak, and Greek.
