I suggest that all those whom downplay HOT as "the history of error" take a look at two
somewhat overlooked items by Debreu, mainly, his Frisch Memorial Lecture as published in
Econometrica  54,6, Nov. 1986, 1259-1270, and his AEA Presidential address, publised in
AER  81,1, March 1991, 1-7.
  
Debreu seems to think  HOT not to be "the history of error", but an important part of
economic discourse, at least on my reading of these pieces.
  
And if Gerard thinks so, who am I, as a lowly "hagiographer", to dispute one of the
foremost theoreticians of modern economics...
