 In what kind of relation does the evaluative content E of a thick term stand to its non-evaluative descriptive content D if they are separable? In  section 2.1  we saw a simple view about the connection: D entails E. But this threatens an is-ought gap which many want to maintain, commits you to Descriptive Equivalence, and makes you vulnerable to the anti-disentangling argument. (From any such D we can construct an independently intelligible purely non-evaluative description with the same extension as the thick term in question.) We also think that in some way selfish actions are bad in a certain way because or in virtue of the agent giving a certain degree of priority to herself over others; the connection doesn’t seem merely conjunctive. Separabilists might then seek to analyze thick terms or concepts as featuring a relation which is explanatory but where D doesn’t entail E. In this vein, Stephan Burton suggests that thick terms can be analyzed as meaning “x is E in virtue of some particular instance of D” (Burton 1992; see also Tappolet 2004). Selfish, for instance, would mean something like “bad in a certain way in virtue of some particular instance of giving priority to oneself over others”. For E to hold in virtue of some particular instance of D is for E to depend on “the various different characteristics and contexts” of D. You might not count as selfish if you benefit yourself over benefiting two other people to the same degree each as you benefit yourself but things may be different if seven other people are in the mix, and what counts as the relevant kind of prioritizing of oneself varies depending on whether the context concerns emotional or financial selfishness, and so on. So D alone isn’t sufficient for E, and the further non-evaluative detail about particular instances of D which is needed for E isn’t built into the meaning of selfish (Burton 1992: 31). This avoids the anti-disentangling argument. For although E is still (contextually) separable from D, D won’t be coextensive with selfish and an outsider’s grasp of the extension of D won’t be enough for her to master how insiders apply selfish. Separabilists might also have other ways of securing these benefits. Brent Kyle argues that Separabilists have no reason to accept an analysis which inserts an explanatory relation into the content of thick concepts, and offers an alternative (discussed below) which also avoids the anti-disentangling argument (Kyle 2020: 916–17, 923).
