Does Heterodoxy Make an Historian of Economics Blind and Deaf?

This note replies to Michel De Vroey's article "The History of Economics as Seen by an HeterodoxEconomist", published in Cahiers d'economie politique nO 38. It disputes De Vroey's statement that my "heterodox" presupposition of the primacy of the wage relationship explains a presentation of Keynes blind on his errors and an evocation of "New classical" macroeconomics deaf to its achievements. Once the assumed heterodoxy is put aside, the analytical disagreement appears to turn on two issues: the possibility for a decline in the real wage to eliminate involuntary unemployment, and the fragility of the theoretical foundations of "New classical" macroeconomics.
