This is one of several unfinished manuscripts or working papers created by Warfield for his ECONOMICS RESEACH studies Petty, Locke, Cantillon and Quesnay are the subjects for Warfield's integrated "book review" of the economic philosophy and thinking of 15-16th centuries. Using brief summaries of writings of each man, and including a lengthy quoted article from Francis Bacon, Warfield is attempting to describe their work by suitable categories. A printout of the paper is in Econ Research Note-binder No. 6.
