Abstract

Chapter 8 argues against the view that the moral rightness of an act is not a reason to perform it, and our reasons are instead the features that make the act right. Philosophers typically defend this view by noting that it seems redundant to take rightness to be an additional reason, once it has been acknowledged that the right-making features are already reasons. The author shows that this argument dramatically overgeneralizes, ruling out all cases in which two or more reasons are arranged in relationships of metaphysical constitution. She then proposes an alternative way of thinking about these metaphysical hierarchies: Rather than assuming that at most one of the facts in each hierarchy is the “real” reason, bearing all the normative weight, it should be accepted that these facts can all be genuine reasons, whose normative weight is shared in virtue of the metaphysical relationships between them. Some tests are offered that can be used to determine which facts occur in metaphysical hierarchies with shared weight, and it is argued that the fact that an act is morally right passes the tests. The author then explains what she takes to be some kernels of truth underlying the redundancy argument, arguing that these phenomena are pragmatic, not metaphysical.
