Volume 9, No. 4 (Winter 2006)
Thomas Sowell is probably best known for his studies of ethnic relations and economics and for his policy oriented works, aimed at a wide popular audience, e.g., Conquests and Cultures: An International History (1998) and Basic Economics: A Citizen’s Guide to the Economy (2004). His Knowledge and Decisions (1980), which earned the praise of F.A. Hayek, showed him to be a gifted theorist as well; and, in On Classical Economics , this versatile author makes a valuable contribution to the history of economics.
Sowell begins with a definition of classical economics:
Since the authoritative tradition that built upon The Wealth of Nations underwent a major change with the marginalist revolution of the 1870s, the end points of classical economics can be reasonably well established, about a hundred years apart. Within that span, there were three men who were clearly classical in every sense: Adam Smith, David Ricardo, and John Stuart Mill.
Others, such as James Mill and J.R. McCulloch, were “fully part of the same tradition, though not of equal stature”; yet others, such as Say and Malthus, “contributed key concepts to classical economics without sharing all its methods and conclusions.” A further group, which includes Marx and Torrens, made less important contributions but still falls within the “larger penumbra” of classical economics.
