Map of west indies for The physiocrats’ support for laissez-faire also influenced Smith, who was a friend though not a follower of Quesnay. Third, the physiocrats based their policy recommendations on different grounds from those of Smith, who advocated utilitarian measures to achieve the greatest good for the greatest number. Instead, physiocrats thought that all policies should simply follow natural law, by which they meant”rather vaguely” their distinction between productive activity (agriculture and mining) and sterile, unproductive activity (manufacturing). The centerpiece of the physiocrats’ natural-law theory was the tableau conomique (economic table), a diagram devised by Quesnay that showed how wealth flowed between productive and unproductive sectors of the economy. Mirabeau said that the invention of the tableau was as significant as the invention of writing and money; Smith regarded its distinction between productive and unproductive activity as misguided. Quesnay’s flow model of the economy can be seen as an echo of his earlier writings about the circulation of blood. Quesnay’s tableau diagram divided society into three columns: productive laborers (agricultural and mining workers); landlords, who were also productive by virtue of making their land available for cultivation; and unproductive laborers (those in manufacturing and commerce).
