Rational intuitions: How reason underlies deontological moral judgments

Joshua Greene's dual process account contends that deontological moral judgments are the result of intuitions that are automatic, emotional and arational. Deontological intuitions cannot be trusted, Greene argues, because they are arationally acquired and deployed. However, the empirical evidence taken to support this view is methodologically flawed and does not support the utilitarianism-rational and deontology-emotional links that dual process theorists postulate. Instead, the available evidence supports a social domain account of moral development, in which the acquisition of moral intuitions is a rational process. That is, one acquires moral intuitions through repeated exposure to and reasoned engagement with moral information. The deployment of moral intuitions is not arational merely because it is not easily open to introspection. Indeed, if introspection were the sine qua non of rationality, then it would follow that the deployment of consequentialist intuitions is also arational. Although deontological intuitions are not infallible, the infirmities of deontological intuitions are equally shared by utilitarian intuitions. Thus, contrary to Greene's recommendation, one need not abandon her deontological moral intuitions. Instead, intuitions - be they deontological or consequentialist - can be useful tools to guide moral reasoning.
