Note 42 — Chapter I · : THE PHYSIOCRATS
R. (Robert) Richards translation
Quesnay’s table consists of a number of columns placed in juxtaposition with a number of zigzag lines which cross from one column to another. If he had been living now he would almost certainly have used the graphic method, which would have simplified matters very considerably, and it is somewhat strange that no one has attempted this with his Tableau. Hector Denis has compared his tables with those of the anatomist and traced a parallel between the links of the economical world and the plexus of veins and arteries in the human body.
His explanation of the Tableau by means of mathematical tables gives him a claim to be considered a pioneer of the Mathematical school. Full justice has been done to him in this respect. An article by Bauer in the Quarterly Journal of Economics, 1890, recognises his claim, and there is another by Oncken in the Economic Journal for June 1896, entitled The Physiocrats as Founders of the Mathematical School. His contemporary Le Trosne is even more emphatic on the point: “Economic science, being a study of measurable objects, is an exact science, and its conclusions may be mathematically tested. What the science lacked was a convenient formula which might be applied to test its general conclusions. Such a formula we now have in the Tableau économique.” (De l’Ordre social, viii, p. 218.)
