Against Internalism-Parity
An alternative argument is provided for rejecting internalism-parity. It is claimed that, from the perspective of internalism-based moral error theorists, categorical reasons for action are more problematic than categorical reasons for belief. This is because there are considerably stronger arguments for thinking that one’s reasons for action are constitutively dependent on one’s desires than for thinking that one’s reasons for belief are constitutively dependent on one’s desires. Three such arguments are considered: from action-explanation, from reasoning, and from paradigmatic-ascriptions. It is claimed that the first of these three arguments clearly does not apply to reasons for belief as to reasons for action. The applicability of the second and third arguments is harder to ascertain.
