First Edition. xxii, 403pp. 1 vols. 8vo. First edition of Keynes' last major work, the most influential economic treatise of the 20th century, in scarce original dust jacket. The General Theory ranks with the Wealth of Nations as an intellectual event and with Malthus' Essay on Population as a guide to public policy. "The world-wide slump after 1929 prompted Keynes to attempt an explanation of, and new methods for controlling, the vagaries of the trade-cycle. First in A Treatise on Money, 1930, and later in his General Theory, he subjected the definitions and theories of the classical school of economics to a penetrating scrutiny and found them seriously inadequate and inaccurate" (PMM).
