----------------- HES POSTING ----------------- I did not mean to suggest or imply that one cannot "learn economics" from studying HE. I think that from various of the three that I have listed one can indeed learn useful economics as well as useful things about economics, if these can be separated. I fully agree with the argument of Michael Perelman that how ideas have evolved are very important in what they are now. We are not simply dealing with a "toolbox" whose past is of no interest, as the "Whiggish" view implies. I shall eschew the invitation to comment on whether or how the listed works fit in or do not fit in with my three categories, but I will not categorically deny that there might be other categories than those I listed.
