Abstract

The supervenience thesis about value customarily expresses two intuitions: (i) that there is some kind of dependence between the value and the natural properties of the value bearer; (ii) that if you assert that x is valuable and if you agree that y is relevantly similar to x, with regard to natural properties, you must be prepared to assert that y too is valuable. R M Hare’s account of supervenience is problematic since it only expresses (ii) but not (i). A solution to this problem is outlined, which ought to be endorsable by a prescriptivist such as Hare.
