Dieter B=F6genhold's reference to Schumpeter as well as Kevin Quinn's re= mark that history of thought is not all history of error bring to mind a quotation that I have used in the first lecture of my graduate history o= f thought classes. Schumpeter is writing about monetary theory: "We know of course that history repeats itself. But it is amazing and perhaps a little sad to observe that economists, swayed by the prevailin= g humors of the hour, also repeat themselves and that, blissfully ignorant= of their predecessors, they believe in each case that they are making unhea= rd of discoveries and building up a brand-new monetary science. However, there are some things to be gleaned from a history of analysis." (Histo= ry of Economic Analysis p. 712) Earlier he writes that the point of history is not to assign credit, but= has real force for the practice of economics: ". . . the advance of economics has been and is being impaired by . . . recurrent losses of previous accumulation of knowledge."
