Normativity, moral realism, and unmasking explanations

Moral Projectivism must be able to specify under what conditions a certain inner response counts as a moral response.

To show this, I develop a number of arguments against moral dispositionalism, which is, nowadays, the most promising version of moral projectivism. In this context, I call into question both David Lewis’ dispositionalist account of colour and Chistine Korsgaard’s procedural realism
