Debunking arguments aim at defeating the justification of a belief by revealing the belief to have a dubious genealogy. One prominent example of such a debunking argument is Richard Joyce’s evolutionary debunking explanation of morality. Joyce’s argument targets only our belief in moral facts, while our belief in prudential facts is exempt from his evolutionary critique. In this paper, I suggest that our belief in prudential facts falls victim to evolutionary debunking, too. Just as our moral sense can be explained (...) in evolutionary terms, so presumably can our tendency to judge our actions in prudential terms. And if the evolutionary explanation of our moral sense has an undermining effect, then so does the evolutionary explanation of our belief in prudential facts. This also undermines moral fictionalism, the view that we have prudential reasons to maintain moral discourse as a fiction. I consider and refute four possible objections to the suggested debunking of our belief in prudential normativity. (shrink)

Moral abolitionists recommend that we get rid of moral discourse and moral judgement. At first glance this seems repugnant, but abolitionists think that we have overestimated the practical value of our moral framework and that eliminating it would be in our interests. I argue that abolitionism has a surprising amount going for it. Traditionally, abolitionism has been treated as an option available to moral error theorists. Error theorists say that moral discourse and judgement are committed to the existence of moral (...) properties, and that no such properties exist. After error theory is established, abolitionism is one potential way to proceed. However, many error theorists suggest that we retain moral discourse as a sort of fiction. I evaluate some attractions of both fictionalism and abolitionism, arguing that abolitionism is a plausible position. No one doubts that error theorists can be abolitionists. However, what has gone largely undiscussed is that it is open to others to be abolitionists as well. I argue that moral realists of a metaphysically robust sort can and perhaps should be abolitionists. ‘Realist abolitionism’ makes for a surprisingly neat theoretical package, and I conclude that it represents an interesting new option in the theoretical landscape.

While Richard Joyce’s moral skepticism might seem to be an extreme metaethical view, it is actually far more moderate than it might first appear. By articulating four challenges facing his approach to moral skepticism, I argue that Joyce’s moderation is, in fact, a theoretical liability. First, the fact that Joyce is not skeptical about normativity in general makes it possible to develop close approximations to morality, lending support to moderate moral revisionism over moral error theory. Second, Joyce relies on strong, (...) contentious conceptual and empirical claims in support of his views. Third, Joyce’s evolutionary debunking argument threatens to backfire, generalizing to all normative judgments. Finally, Joyce fails to offer an adequate account of the normativity of desire. Each of these four challenges can be either sidestepped or embraced by radicalizing and defending a global form of normative skepticism. There are thus several ways in which global normative skepticism appears to be in a more robust dialectical position than Joyce’s moral skepticism. Furthermore, I argue, Joyce’s arguments against global normative skepticism are unconvincing. While this discussion is framed in terms of Joyce’s work, its arguments will apply to other moral skeptics who are not also global normative skeptics. The result is an invitation for Joyce and other moral skeptics to leave these problems behind and join the radical camp. (shrink)

Jonas Olson presents a critical survey of moral error theory, the view that there are no moral facts and so all moral claims are false. Part I explores the historical context of the debate; Part II assesses J. L. Mackie's famous arguments; Part III defends error theory against challenges and considers its implications for our moral thinking.
