Comments on Four Papers on Economics and Human Heterogeneity

摘要

These comments focus on some issues raised in the papers by Dimand, Peart and Levy, Cot, and Leonard. These papers are fascinating, but not without weaknesses. It is argued that Dimand's presentation of what he calls the "general principle" of classical economics is misconceived. There is a confusion in this paper between the classical view of equal capacity and the much newer concept of equally rational actual performance. Peart and Levy discuss the idea of unequal capacity for pleasure in Edgeworth, but do not draw a link back to the idea in J. S. Mill of different qualities of pleasure. Cot and Leonard provide informative accounts of the American eugenic movement and its links to progressivism, but with an insufficient degree of distinction between the various positions and agendas that were concerned.
