Anthony gives a witty illustration with a distinction between historical pieces of information that are relevant for crafting a winning strategy for the impending battle of North Africa and those that are not. He concludes: > What I am interested in is tactics, and if by making rational > reconstructions of byegone battles I can learn things that will make > me a better tactician, that's what I'm going to do. I think what some of Samuelson's critics are saying is that he hasn't done a good enough "rational reconstruction" of bygone battles. Take, for example, the battle over the role of saving (rather than consumption) in economic growth during the classical period. Smith, Say, Ricardo, (Malthus) and J.S. Mill all emphasized that saving promotes economic growth whiles consumption (or current enjoyment by income earners) retards it. J.M Keynes comes along in 1930 (_Treatise_) with his paradox of thrift (saving) argument, further elaborated in his1936 _General Theory_ in contradiction to classical theory. Wasn't it bad rational reconstruction for Samuelson to have crafted the Keynesian argument in terms of algebra and geometry for millions of students to learn the false claim that there is such a thing as a paradox of thrift in their macroeconomics textbooks (I learned that from Samuelson's _Economics_ in the late 1960s), only perhaps to struggle to learn the contra-argument in courses in development economics? I could cite some other examples in macroeconomics where Samuelson could have done a better job at rational reconstruction of bygone battles. I'm thus left wondering about the usefulness of the history of economic analysis (HEA), of which Samuelson is the greatest practitioner, according to Anthony, as against that of intellectual history (IH), in promoting scientific economics in contrast to scientism.
