From a critical perspective, it may be argued that there remains a significant gap in Hume’s scheme as we have so far described it. Even if we discard the aspirations of the morality system, any credible naturalistic theory of moral responsibility needs to be able to provide some account of the sorts of moral capacity involved in exempting conditions, whereby we deem some individuals and not others as appropriate targets of moral sentiments or “reactive attitudes”. As it stands, what Hume has to say on this subject is plainly inadequate. According to Hume, it is an ultimate inexplicable fact about our moral sentiments (qua calm forms of the indirect passions of love and hate) that they are always directed at people, either ourselves or others. This account leaves us unable say why some people are not appropriate objects of moral sentiments (e.g. children, the insane, and so on). There are, however, several available proposals for dealing with this gap. Perhaps the most influential proposal is to adopt some general theory of reason-responsiveness or rational self-control. According to accounts of this kind, responsible agents need to have control over their actions, where this involves performing “those actions intentionally, while possessing the relevant sorts of normative competence: the general ability to grasp moral requirements and to govern one’s conduct by light of them” (Wallace, 1994: 86). While proposals of this general kind help to plug a large gap in Hume’s theory, they also suggest a particular understanding of moral responsibility that is not entirely in keeping with Hume’s own account.
