The Mismeasure of Wealth: Essays on Marx and Social Form gathers Patrick Murray’s essays reinterpreting Marx and Marxian theory published since his Marx’s Theory of Scientific Knowledge (1988), along with a previously unpublished essay and an introduction. Murray’s essays concentrate on Marx the historical materialist, the investigator of historically specific social forms of wealth and labour. There is no production in general; the production of wealth always involves specific social forms and purposes that matter in many ways. Marx’s attention to the dynamics and far-reaching consequences of historically specific social forms – in particular those that are constitutive of the capitalist mode of production – sets him off from classical political economy and traditional Marxism. In probing Marx’s dialectical accounts of the commodity, value, money, surplus value, wage labour and capital, The Mismeasure of Wealth establishes Marx’s singular relevance for critical social theory today.
