To what extent can we as a community legitimately require individuals to contribute to producing public goods? Most of us think that, at least sometimes, refusing to pay for a public good that you have enjoyed can involve a kind of 'free riding' that makes it wrong. But what is less clear is under exactly which circumstances this is wrong. To work out the answer to that, we need to know why it is wrong. I argue that when free riding is wrong, the reason is that it is unfair. That is not itself a very controversial claim. But spelling out why it is unfair allows us to see just which forms of free riding are wrong. Moreover, it supplies a basis from which some more controversial conclusions can be defended. Even if a public good is one that you have been given without asking for it or seeking it out, it can still be wrong not to be prepared to pay for it. It can be wrong not to be prepared to pay for public goods even when you do not receive them at all. And furthermore, it can be right to force you to do so.

Are there good grounds for thinking that the moral values of action are to be derived from those of character? This virtue ethical claim is sometimes thought of as a kind of normative ethical theory; sometimes as form of opposition to any such theory. However, the best case to be made for it supports neither of these claims. Rather, it leads us to a distinctive view in moral epistemology: the view that my warrant for a particular moral judgement derives from my warrant for believing that I am a good moral judge. This view seems to confront a regress-problem. For the belief that I am a good moral judge is itself a particular moral judgement. So it seems that, on this view, I need to derive my warrant for believing that I am a good moral judge from my warrant for believing that I am a good judge of moral judges; and so on. I show how this worry can be met, and trace the implications of the resulting view for warranted moral judgement.

What is the significance of empirical work on moral judgement for moral philosophy? Although the more radical conclusions that some writers have attempted to draw from this work are overstated, few areas of moral philosophy can remain unaffected by it. The most important question it raises is in moral epistemology. Given the explanation of our moral experience, how far can we trust it? Responding to this, the view defended here emphasizes the interrelatedness of moral psychology and moral epistemology. On this view, the empirical study of moral judgement does have important implications for moral philosophy. But moral philosophy also has important implications for the empirical study of moral judgement.
