Joseph Raz is one of the world's leading philosophers of law, and in his Seeley Lectures he reflects critically on one of the central tenets of ethical thought, the view that values are universal. He concludes that we should try to understand what is and what is not entailed by the universality of values, with such an understanding central to the future hopes of mankind, rather than abandoning the belief altogether. This is a concise humane account of some fundamental questions of social existence.
