According to unconditional motivational internalism, there is an a priori constraint on an agent's forming a sincere moral judgement, namely that she is, at least to some minimal extent, motivated to act as it dictates. In order to undermine this internalist position, proponents of motivational externalism typically appeal to the possibility of the amoralist—i.e. an individual who makes sincere moral judgements, but who is completely unmoved to act accordingly. This strategy is known as the challenge of amoralism. Against this strategy, (...) I will argue that in order to represent a genuine case of amoralism, and a credible counterexample to unconditional motivational internalism, an agent would have to simultaneously satisfy an epistemically inconsistent set of conditions. Thus, the conclusion I will attempt to defend in this paper is that the challenge of amoralism does not succeed in posing a legitimate threat to unconditional motivational internalism. (shrink)
