He also brings up Adam Smith's failure to support propertarian dogma. Gavin Kennedy mostly endorses Schlefer's view of Smith.
Which brings me to my question. Suppose you accept the distinction between scientific political economy and vulgar political economy. Some see both types of political economy in Adam Smith. He contains both esoteric and exoteric elements. But who would you say was the first writer on scientific political economy? I think you can find scientific elements in Quesnay. After all the study of schemes of expanded reproduction builds on Quesnay's Tableau. Maybe William Petty is the answer to my question. Or maybe one should go back all the way to Aristotle.
