Louis F. Post,
The basic facts of economics
(1927)
“ Utility is an absolute term indicative of essential desirability. Value is a relative term indicative of the relative Utility of commodities; or, more precisely, of the degree of desirability of one variety of Labor or Land or form of Wealth in comparison with other varieties. One variety of Labor or of Land or of Wealth may be twice as desirable as another, unit for unit, in which case one unit of the former will exchange in Trade for two units of the latter. Thus the relative Utility of a Commodity is indicated in Trade by its Value. ”
