In “Intrinsic value: some comments on the work of G. E. Moore” (Philosophy July 1958), I argued that Moore implies that intrinsic value is measurable, but has never suggested any method of measuring it. In this note I shall outline a method which is derived, but not exactly copied, from some of the analyses which economic theorists have given of “cardinal utility”. A survey of some of the economic discussions is given by S. A. Ozga in “Measurable utility and probability” (Econ. J. Sept. 1956).
