 Of course, this strategy for defending generalism is for good reason a highly controversial one. For a start, nobody has come close to offering a fully reductive definition of predicates like “is morally right” which has met with widespread assent. Moreover, some philosophers are sceptical of the very idea that knowing the meaning of a word (or possessing a concept) is already enough, in principle, to know how to live a good life. In way, this concern about pulling a highly substantive rabbit out of a purely semantic/conceptual hat can be seen as what lies behind one of the historically most influential arguments against analytic naturalism, namely G.E. Moore’s “Open Question Argument” (Moore 1922 [1903]). Finally, anyone who is initially sympathetic to particularism is very unlikely to find analytic naturalism an ex ante plausible view, given how trivially it entails a very robust form of generalism. There is a sense, then, in which this strategy for defending generalism, however sound it might turn out to be, is unlikely to convince anyone who needs convincing (cf. Jackson, Pettit, &amp; Smith 2000—the argument there seems ultimately to turn into a version of this first strategy).
