This article deals with D. Parfit’s moral philosophy, as it has recently been drawn in On What Matters. After specifying the realistic Metaethics of Parfit’s project, I examine his polemic with moral expressivism and its interpretation of the kantian categorical imperative. Since one of the most original aspects of this interpretation is the idea of the control over the procedures concerning the agent, I show how this should lead to a control over the relevant information about agent. This perspective could suggest that the fate of ethics is political philosophy.
