The limits of moral dumbfounding

Abstract

In moral psychology, “psychological rationalism” is the view that moral judgments are caused by a process of reasoning. Jonathan Haidt argues against this view by showing that people succumb to “moral dumbfounding”—they cannot adequately provide reasoning for their moral judgment. I argue that this evidence undermines psychological rationalism only if the view is committed to two claims about reasoning: (a) reasoning must meet an adequacy condition, and (b) reasoning must be sufficiently conscious. I argue that plausible variants of psychological rationalism are not committed to these requirements. Thus, the efficacy of the dumbfounding objection is more limited than it might initially seem.
