Neil Sinclair is Professor of Philosophy and former Head of Department at the University of Nottingham. His primary philosophical interests are in anti-realist theories of moral practice, in particular expressivism. His book, Practical Expressivism (OUP 2021) argues that the practical, interpersonal problem-solving function of moral concepts can explain the realist-seeming norms at play in morality. This has led to more recent interests in the nature of prudential and aesthetic normativity, functional explanation, and conceptual engineering. He has also written papers on the nature of moral explanations, expressivist accounts of reasons, presumptive arguments for moral realism, debunking arguments and, more recently, the ethical philosophy of C.L. Stevenson. He is an area editor for Ergo (an open access journal of philosophy).
