My discussion of Mill on these matters is clearly indebted to Korsgaard's discussion. I speculate that one reason for chapter 3's comparative neglect is the influence of an idea that (ironically) one sees emerging in inchoate form in the chapter itself: the idea that metaphysical and epistemological considerations are irrelevant or neutral with regard to moral claims. This idea became conceptually (and, later, professionally) enshrined in the distinction between metaethics and normative ethics.

⁴ The two kinds of force need to be separated in order to discuss the relationship between how moral people are and how moral people should be. One could hold that people are not naturally suited to living morally and yet still think that moral concerns should, as a normative matter, be given the highest importance. Alternatively, one might think that humans are easily ‘moralized’ but consider them mistaken, from a normative point of view, in giving high priority to the demands of morality.

⁶ See, for example, Smith, Michael, The Moral Problem (Oxford: Blackwell, 1994), p. 7Google Scholar. Note that we can think of the motivational power of morality as a given and then use this fact to test the explanatory appeal of rival moral theories. Alternatively, we can think of the practicality requirement as a normative demand on moral theories: i.e. they ought to sustain our ethical motivation.

⁸ As Simon Blackburn puts it in Ruling Passions (Oxford: Oxford University Press, 1998), many think that his form of sentimentalism ‘smells of sulphur’ (p. vi). The accusation against sentimentalism, as his evocative phrase suggests, has a long history.

¹³ Gilbert Harman uses a similar kind of argument to Mill in his ‘Moral Relativism’, Moral Relativism and Moral Objectivity, ed. G. Harman and J. J. Thompson (Cambridge Mass.: Blackwell, 1996), although Harman's argument is on behalf of his moral conventionalism. Harman writes: ‘[I]t might be thought that morality loses its normative force if it does not have a nonconventional source. But that is just a mistake if moral conventionalism is true [for according to it] there is no such thing as objective absolute normative force. Morality does not lose that sort of normative force, because it never had it in the first place’ (pp. 27–8). You can see Harman's point: if conventionalism is true, it is true already. But note also the problem with the argument: if moral conventionalism comes to be believed, then arguably something will be lost that was present in moral practice in the first place, namely the belief that morality has a non-conventional source. And the skeptical worry concerns what might follow from this lost belief.

¹⁵ Or, to adapt a point of Anscombe's, whenever you want to unbind yourself, can't you always overturn the legislation by a vote of 1–0? Anscombe, of course, notoriously believed that any notion of self-legislation was incoherent because legislation requires a ‘superior power’ in the legislator. See Anscombe, G. E. M., ‘Modern Moral Philosophy’, Virtue Ethics, ed. Crisp, Roger and Slote, Michael (New York: Oxford University Press, 1997), p. 27Google Scholar. She names Kant as her target but does not consider, even to reject it, the Kantian idea that one aspect of the self can legislate over another.

²⁰ This, in a sense, is Kant's view, although of course the internal/external distinction is, in another sense, preserved by Kant, albeit now located inside the self. I discuss this distinction in relation to moral skepticism in section 5 of my ‘Internalism and the Self: Lessons from Korsgaard's Kantian Critique of Williams’, Southwest Philosophy Review 23.1 (Jan. 2007).

²³ Note, however, that one could argue that the value given to self-interest is indeed underpinned by a mistaken metaphysics of the self. Derek Parfit argues this case in Reasons and Persons (New York: Oxford University Press, 1984). See also Susan Wolf's rejoinder to Parfit: ‘Self-Interest and Interest in Selves’, Ethics 96 (July 1986), pp. 704–20. More generally, a number of political theorists have argued that modernity is characterized by, in C. B. Macpherson's phrase, a ‘possessive individualism’ that has metaphysical components.

²⁵ Charles Taylor has defended this view. See, for example, his ‘Ethics and Ontology’, The Journal of Philosophy, C.6 (June 2003), pp. 305–20. George I. Mavrodes argues for the importance of the ‘deep grounding’ (p. 220) of morality in ‘Religion and the Queerness of Morality’, Rationality, Religious Belief, and Moral Commitment, ed. Robert Audi and William J. Wainwright (Ithaca: Cornell University Press, 1986). He defends the following claim (one that he associates with Platonism, Christianity, and, in this quotation, Kantianism): ‘there cannot be, in any “reasonable way”, a moral demand upon me, unless reality itself is committed to morality in some deep way. It makes sense only if there is a moral demand on the world too and only if reality will in the end satisfy that demand’ (p. 220). Mavrodes argues, in effect, for the exact thesis that Mill aims to rebut, viz. that taking morality seriously is incompatible with the metaphysics of modern scientific naturalism.

²⁶ One might object, as Kant did, that the desire to avoid punishment (or receive reward) is not really a moral reason: nonetheless, as Kant also acknowledged, it is a reason to be moral (that is, to conform one's actions with moral norms). The presence of such metaphysical reasons within various models of morality – and what the consequences might be of removing such metaphysical guarantees (and thus exposing reasons to be moral to contingency and luck) – has been subjected to a deep exploration in the work of Bernard Williams. See, in particular, his ‘Persons, Character and Morality’ and ‘Moral Luck’, Moral Luck (Cambridge: Cambridge University Press, 1981) and Ethics and the Limits of Philosophy (Cambridge, Mass.: Harvard University Press, 1985).

²⁷ Mill clearly has Christianity primarily in mind, although he does cite other religions in Utilitarianism.

²⁸ Mill, Utilitarianism, p. 74, emphasis added. One can see how remarks such as this point to the development (alluded to in n. 2 above) of a separation of the internal substantive content of morality from such matters as its metaphysical status. See also Mill, Utilitarianism, p. 68.

³⁶ Mill writes in Utilitarianism: ‘[A]s men's sentiments, both of favour and of aversion, are greatly influenced by what they suppose to be the effects of things upon their happiness, the principle of utility . . . has had a large share in forming the moral doctrines even of those who most scornfully reject its authority’ (p. 51). Mill argues that application of the utility principle admits of ‘indefinite improvement’ (p. 70), but it is clear that he expects the pace of social improvement to increase once the ‘tacit influence’ (p. 51) of the utility standard on conventional morality (and on rival moral philosophies) is recognized and consciously affirmed.

Notice that Williams is writing from the perspective of someone for whom moral naturalism is a revisionary position: this is the person for whom moral obligation might not have the resonance it once possessed. What about the person who was raised as a moral naturalist, we might wonder?
