6 Of course, the scientific criteria are relatively vague and not uncontroversial, but that is not of immediate relevance here.
7 What about numbers? Will they be posited by the best scientific explanation? Do they have a causal role? This is a controversial issue, but I would argue in the negative to both questions. The best contemporary discussion of this issue is, of course, Hartry Field's Science Without Numbers (Princeton: University Press 1980).

10 Note that for the present purposes it doesn’t matter whether my characterization of the distinction between the two models captures the historical distinction between primary and secondary qualities. Nor does it matter whether shape facts and color facts are primary quality model and secondary quality model facts respectively. All that matters is that there is a genuine distinction between the two models.
11 McDowell takes Mackie's views about secondary qualities from Mackie’s Hume's Moral Theory (London: Routledge & Kegan Paul 1980), 51-2, and from Mackie's Problems from Locke (Oxford: Clarendon Press 1976), 15-20.
12 The receptive mechanism might, but need not, involve input channels other than the usual five senses. Either way, the manner in which the mechanism processes its input would be totally unlike anything currently posited by science.
13 Campbell and Pargetter defend at length the secondary quality model (although not under that title) in ‘Goodness and Fragility.’ Gilbert Harman's functional account inch. 4 of The Nature of Morality is also a secondary quality model.
