First edition, "extremely rare" (The New Palgrave), of "one of the most important contributions in the history of the development of mathematical economics" (Theocharis, Early Developments in Mathematical Economics, p. 62). "His book is remarkable for its mathematical treatment of production, capital, money and the theory of exchange" (Blaug). Although influenced by Physiocratic thought, he rejected the theory that only the land is productive and was in many respects surprisingly modern. Isnard was one of the first writers to attempt a mathematical definition and a mathematical proof of an economic equilibrium. For a detailed analysis of this pioneering work, see the long note by R. F. Hébert in The New Palgrave.
