FIRST EDITION OF THE MOST INFLUENTIAL ECONOMIC TREATISE OF THE 20TH CENTURY. "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 423).
