of reasoning which has been proclaimed exceedingly keen, JAMES MILL, the father of the well-known English economist, John Stuart Mill, says: "Whatever . . . be the amount of the annual produce, it never can exceed the amount of the annual demand . . . Of two men who perform an exchange, the one does not come with only a supply, the other with only a demand; each of them comes with both a demand and a supply. . . . The supply which he brings is the instrument of his demand; and his demand and supply are of course exactly equal to one another. It is therefore, impossible that there should ever be in any country a commodity or commodities in quantity greater than the demand, without there being, to an equal amount, some other commodity or commodities in quantity less than the demand."[1]


  1. In November, 1807, William Spence published a pamphlet in England under the title: "Britain Independent of Commerce." The principle set forth in this pamphlet was further elaborated by William Cobbet in his "Political Register" under the virulent title, "Perish Commerce." To this James Mill replied in 1808 in his "Defence of Commerce" which contains the passage quoted above from his "Elements of Political Economy" (p. 190–193, Transl.). In his controversy with Sismondi and Malthus on commercial crises, J. B. Say appropriated this clever device, and as it would be difficult to point out with what new idea this comical "prince de la science" had enriched political economy, his continental admirers have trumpeted him as the man who had unearthed the treasure of the metaphysical balance of purchases and sales; as a matter of fact, his merits consisted rather of the impartiality with which he equally misunderstood his contemporaries, Malthus, Sismondi and Ricardo.
