Paul Katsafanas explores how we can justify normative claims such as 'murder is wrong'. He defends an original account of constitutivism - the view that we do so by showing that agents become committed to them in virtue of acting - and resolves philosophical puzzles about the metaphysics, epistemology, and practical grip of normative claims.
