Thus spake Edwin Cannan, professor of economics at the London School of Economics (LSE) and member of the Council of the Royal Economic Society, publisher of The Economic Journal (EJ). From 1911 to 1945, Keynes was editor of the EJ, arguably the most prestigious journal in British economics. At the time of Cannan's remark in February 1934, when the early drafts of The General Theory of Employment, Interest, and Money were taking shape and Keynes had assumed leadership of a movement to reconceptualize economic theory, he not only had ideas of his own but an uncommonly robust sense of their importance. Although Keynes's conception of the ultimate purpose of economic theory remained true to the Marshallian tradition in which he was trained— forging scientific tools to improve the lot of humankind—his immediate objective was less pacific: the destruction of classical economics (Keynes 1935, p. 36). In his metaphor, classicism was a citadel fortified by an invincible superstructure constructed over generations by economists of great theoretical power and ingenuity, from David Ricardo and John Stuart Mill to Alfred Marshall and his own contemporary, Arthur Cecil Pigou. Because the citadel was vulnerable only in its “fundamental groundwork,” an assault would succeed only by undermining this foundation (Keynes 1973a, p. 533).
