¹⁷ Street uses an example from Gibbard, that of an ideally coherent Caligula: ‘Humean constructivists . . . think that things are pretty much as they appear with regard to such a case – in other words, that just as it seems on superficial inspection, one can indeed value torturing others above all else and be entirely coherent in doing so.’ Street, ‘What is Constructivism’, p. 371; Gibbard, Allan, ‘Morality as Consistency in Living: Korsgaard's Kantian Lectures’, Ethics 5.5 (1999), pp. 140–64, at 140CrossRefGoogle Scholar.

¹⁸ Street considers that they are both anti-realist Humean views, but says nothing else, as far as I know, about the relationship between them. Sharon Street, Objectivity and Truth: You’d Better Rethink It (unpublished), p. 4.

²⁰ Street, Objectivity, p. 36.

²¹ Street, ‘Coming to Terms’, pp. 43–4. Street talks in terms of values (again, interchangeably with normative judgement and taking oneself to have a reason) rather than desires, as she believes the talk of desires tends to make the evaluative content of Humean views seem superficial and arbitrary. There is in traditional Humean talk no clear distinction between desires that are fleeting, of little importance in relation to our other desires, and associated with a narrow range of emotions, and those that are lifelong, of great importance in relation to our other desires, and associated with a wide range of affective attitudes. For Street, values thus exist on the same spectrum as desires, but are characterized by greater discipline, range and depth of associated emotional experience, and structural complexity. (For Street's account, see her What is Constructivism, pp. 42–4.)

²² Michael Ridge argues that Street's view is ‘a sophisticated species of metaethical subjectivism, rather than an entirely novel metaethical theory’. I tend to agree with Ridge, but believe that the sophistication of Humean constructivism is significant and useful. Michael Ridge, ‘Kantian Constructivism: Something Old, Something New’, Constructivism in Practical Philosophy, pp. 138–57, at 157.

²³ Reasons internalism is also compatible with some non-Humean views. For example, Korsgaard's view holds that practical reasons must be internal: Christine Korsgaard, ‘The Normativity of Instrumental Reason’, Ethics and Practical Reason, ed. G. Cullity and B. Gaut (Oxford, 1997), pp. 215–54, at 215 n. 1.

⁸⁷ These three claims do not represent the whole of Mill's argument, omitting most importantly the aggregation premise – that as each person's happiness is a good to that person the general happiness is a good to the aggregate of persons (Mill, Utilitarianism, 4.3), which is not relevant to my purposes here. For formulations of the complete argument see Brink, Mill, sect. 2.11, and Quinton, Utilitarian Ethics, pp. 59–60.

⁹⁵ The problematic aggregation premise does not follow easily from this reading, but does not follow easily from any other reading I know of either. It is not possible to discuss possible solutions here, but a Humean constructivist reading doesn't hang on the aggregation premise; a Humean constructivist reading, like some other views, can hold that Mill is simply wrong that happiness is aggregative.

⁹⁶ Mill, Utilitarianism, 4.1.

⁹⁷ This view means that Mill's comment that desire is the sole evidence for desirability in the way that seeing something is the only evidence for visibility and hearing something the only evidence for audibility is a mistake if taken as an exact parallel (Mill, Utilitarianism, 4.3). But the analogy is commonly taken not to be intended as an exact parallel (Crisp, Mill on Utilitarianism, p. 75; West, Mill's Utilitarianism, p. 78).
