Recent empirical work appears to suggest that the moral intuitions of professional philosophers are just as vulnerable to distorting psychological factors as are those of ordinary people. This paper assesses these recent tests of the ‘expertise defense’ of philosophical intuition. I argue that the use of familiar cases and principles constitutes a methodological problem. Since these items are familiar to philosophers, but not ordinary people, the two subject groups do not confront identical cognitive tasks. Reflection on this point shows that (...) these findings do not threaten philosophical expertise—though we can draw lessons for more effective empirical tests. (shrink)

The evidential value of moral intuitions has been challenged by psychological work showing that the intuitions of ordinary people are affected by distorting factors. One reply to this challenge, the expertise defence, claims that training in philosophical thinking confers enhanced reliability on the intuitions of professional philosophers. This defence is often expressed through analogy: since we do not allow doubts about folk judgments in domains like mathematics or physics to undermine the plausibility of judgments by experts in these domains, we (...) also should not do so in philosophy. In this paper I clarify the logic of the analogy strategy, and defend it against recent challenges by Jesper Ryberg. The discussion exposes an interesting divide: while Ryberg’s challenges may weaken analogies between morality and domains like mathematics, they do not affect analogies to other domains, such as physics. I conclude that the expertise defence can be supported by analogical means, though care is required in selecting an appropriate analog. I discuss implications of this conclusion for the expertise defence debate and for study of the moral domain itself. (shrink)

In a recent paper, Giubilini and Minerva argue for the moral permissibility of what they call ‘after-birth abortion’, or infanticide. Here I suggest that they actually employ a confusion of two distinct arguments: one relying on the purportedly identical moral status of a fetus and a newborn, and the second giving an independent argument for the denial of moral personhood to infants (independent of whatever one might say about fetuses). After distinguishing these arguments, I suggest that neither one is capable (...) of supporting Giubilini and Minerva's conclusion. The first argument is at best neutral between permitting infanticide and prohibiting abortion, and may in fact more strongly support the latter. The second argument, I suggest, contains an ambiguity in its key premise, and can be shown to fail on either resolution of that ambiguity. Hence, I conclude that Giubilini and Minerva have not demonstrated the permissibility of infanticide, or even great moral similarity between abortion and infanticide. (shrink)

This chapter discusses the philosophical relevance of empirical research on moral cognition. It distinguishes three central aims of normative ethical theory: understanding the nature of moral agency, identifying morally right actions, and determining the justification of moral beliefs. For each of these aims, the chapter considers and rejects arguments against employing cognitive scientific research in normative inquiry. It concludes by suggesting that, whichever of the central aims one begins from, normative ethics is improved by engaging with the science of moral (...) cognition. (shrink)
