Le Capital : Livre premier, Le procès de production du capital

Capital: A Critique of Political Economy (German: Das Kapital. Kritik der politischen Ökonomie), also known as Das Kapital (German: [das kapiˈtaːl]), is a foundational theoretical text in Marxist philosophy, economics, and politics by Karl Marx. His magnum opus, the work is a critical analysis of political economy, meant to reveal the economic patterns underpinning the capitalist mode of production. Das Kapital is in three volumes, of which only the first was published in Marx's lifetime (1867); the others were completed from his notes and published by his collaborator Friedrich Engels in 1885 and 1894. The central argument of Das Kapital is that the motivating force of capitalism is in the exploitation of labour, whose unpaid work is the ultimate source of surplus value and profit. Beginning with an analysis of the commodity, Marx argues that the capitalist mode of production is a historically specific system where social relations are mediated by commodity exchange. He posits a labour theory of value, contending that the economic value of a commodity is determined by the socially necessary labour time required for its production. Under this system, the worker's capacity to labour (their labour power) is sold as a commodity, but its use-value—the ability to create new value—is greater than its exchange-value (the wage), allowing the capitalist to extract surplus value. This process drives capital accumulation, which in turn fosters technological change, the creation of a reserve army of labour, and a long-term tendency of the rate of profit to fall, leading to economic crises and intensifying class conflict. In developing his critique, Marx synthesised and critiqued three main intellectual traditions: the classical political economy of thinkers like Adam Smith and David Ricardo, the German idealist philosophy of Georg Wilhelm Friedrich Hegel, and French socialist thought. His dialectical method aimed to uncover the internal contradictions and historical transience of capitalism. A key theme is commodity fetishism, the process by which the social relations of production are obscured and appear as objective, natural relations between things. Volume I focuses on the production process, Volume II on the circulation of capital, and Volume III on the process as a whole, examining the distribution of surplus value into profit, interest, and rent. Das Kapital is one of the most influential works of social science ever written. Its analysis has been foundational to the international labour movement, socialist and communist political parties, and a wide range of academic disciplines, including sociology, political science, and philosophy. It remains central to Marxian economics and has been highly influential in Western Marxism, critical theory, and cultural studies. The work has been subject to extensive debate and criticism since its publication, particularly concerning its labour theory of value, its predictions about the future of capitalism, and its association with 20th-century communist states.
