Abstract

In lieu of an abstract, here is a brief excerpt of the content:Norms, Conventions, and PsychopathsNeil Levy (bio)Keywordspsychopathy, morality, conventions, responsibilityI am grateful to my commentators for their provocative challenges to my claim that psychopaths ought to be excused moral responsibility for their wrongdoing owing to their (alleged) failure to grasp the moral/conventional distinction. I have learned from all the commentators—now, and in some cases in the past as well—and I am sincerely honored by their having taken my work seriously enough to comment on it, even if only to take issue with it. In what follows, I shall attempt to reply to their main criticisms. As will shortly become clear, I do not here have the space for anything like adequate responses. Instead, I shall have to content myself with programmatic statements of how such responses might go. Let me admit at the outset that until the details of these responses are fully worked out, and the relevant empirical research conduced, I cannot be sure that the responses will succeed. Nevertheless, there are grounds for confidence, given the available data.Because there is some overlap between the criticisms, I shall address some of them—those of Blair, Nichols, and Vargas—by topic rather than by commentator, before turning to Mullen and Matravers.Is the Ability to Understand the Moral/Conventional Distinction a Necessary Condition of Aptness for Moral Responsibility?Blair, as well as Vargas and Nichols, suggests that an agent's knowing that an action is against the rules might be sufficient to ground responsibility for performing that action, even if the agent lacks the ability to draw the moral/conventional distinction. As Blair points out, we do not reserve blame only for those who violate moral rules. Blame, and sometimes punishments, are also meted out to those who violate merely conventional norms. Because psychopaths can understand conventional norms perfectly well, they may therefore seem to be appropriate targets of at least some kind of moral blame.But is it really the case that agents are (ever) blameworthy for violating conventional norms alone? Many philosophers, for instance when considering the morality of civil disobedience, have argued that conventional norms are typically backed by second-order moral norms. Hence, for many or all conventional norms, there is a (defeasible) moral obligation not to violate that norm, an obligation independent of the content of the conventional norm; it is because there are such second-order moral obligations that agents are blameworthy for violating conventional norms. [End Page 163] But if this is the case, then the fact that we sometimes blame agents for violating conventional norms is not evidence against the claim that the ability to grasp moral norms is a necessary condition of blameworthiness. There is no reason to think that psychopaths will find it any easier to grasp second-order moral norms than first-order (of course, they may understand that there are such things as second-order norms—norms concerning norms—but for them such norms will only be conventional). In fact, it might be more difficult to understand the moral force of second-order moral norms than first, inasmuch as the harms caused by violating such norms are emotional and not physical. Normal subjects invest (some) conventional norms with moral significance, and it is for this reason that we regard violations of such norms as apt to give rise to blame; lacking the ability to draw the moral/conventional distinction, psychopaths cannot invest such norms with moral significance. Once again, for them these norms are merely conventional, and they therefore fail to grasp the full significance of violating them.It might be objected that if conventional transgressions are (sometimes) backed up by second-order moral norms, children would not classify them as neatly as they do. They would misclassify some conventional norms as moral, insofar as they are backed up by second-order moral norms. They would therefore deny that violations of conventions are permissible on the say-so of an authority. There are two possible explanations of children's classifications, compatible with the suggestion that some conventions are backed by second-order moral norms. First, it may be that greater cognitive sophistication is required to grasp second-order moral norms than...
