Abstract

Internalism – here the view that moral judgments entail motivation – is often taken to support non-cognitivism about morality. However, Michael Smith has defended a variety of it in combination with a cognitivist account of morality. Despite the eminence of Smith’s contribution, his case in favour of internalism is flawed. I distinguish several internalist positions and argue that Smith’s version, unlike standard ones, expresses a view about, not the nature of the state one is in when one makes a moral judgment, but the norms of practical rationality. I then defend the externalist appeal to the possibility of amoralism. Such an appeal need not beg the question against internalism and can in any case be backed up by independent considerations. Moreover, neither of Smith’s two main arguments in favour of internalism – the reliable connection argument and the appeal to rationalism about moral requirements – are sound. Having shored up the case for externalism and dismissed Smith’s case against it, I end the essay with a suggestion as to why many philosophers have been attracted to internalism even though the theory turns out to be ill-founded.
