ABSTRACT
If moral properties are taken as supervenient properties and descriptive or naturalistic properties are taken as base properties, we have the doctrine of moral supervenience: the moral properties of persons, acts, and other objects supervene on their descriptive or naturalistic properties. One interesting application of the supervenience concept is mereological supervenience, the doctrine that the character of a whole is supervenient on the properties and relationships holding for its parts. This apparently calls for two distinct domains: one domain consisting of wholes and another consisting of their parts. It would be of interest to know how a dependency relation can be formulated across two domains. From a metaphysical point of view, supervenience claims having the form of uncoordinated multiple-domain supervenience seem perched on a rather unstable position, crying out for reformulation in terms of a more structured supervenience relation.
