I wrote a book about this very subject as part of what I could do from preventing the European Research Council from turning the history of economic thought into a sub-sub-set of the History of the Human Memory. Now it is part of the very ethos of HET in Europe:

The issues of inequalities confirm the ESHET’s firm belief that the study of the history of economic thought should in no way be disconnected from current issues in economics and beyond, and could in fact help provide historical perspectives on standard views about the subject.

Oh yes indeed. There will come a time, and it’s not far off, when economists will start to relearn their history which, among other things, contains a vast storehouse of ideas that have been lost or forgotten but are as valid if not more so than the ones we now have in our currents economic texts.
