 Leaving aside the controversial question of whether we can separate possession conditions of concepts from attribution conditions, it might be asked whether Burge’s social externalism can be employed to support CE normativity. Burge’s argument depends on the (empirical) assumption that the individual is committed to the community practice (Burge 1979: 94–95, 101–102; Millar 2004: 182). But if the normativity in question is made conditional on the individual’s commitment to the community, it does not follow that content is essentially normative. After all, an individual who is not thus committed would still have concepts. (Equally, in the case of the experts, the suggested normative dimension would seem to drop out.) What would be required, rather, is an argument to the effect that the concept expressed is necessarily determined by the community practice, independently of \(S\)‘s commitments.
