El capital

Das Kapital, also known as Capital: A Critique of Political Economy or sometimes simply Capital (German: Das Kapital. Kritik der politischen Ökonomie, pronounced [das kapiˈtaːl kʁɪˈtiːk deːɐ poˈliːtɪʃn̩ økonoˈmiː]; 1867–1883), is a foundational theoretical text in materialist philosophy, critique of political economy and politics by Karl Marx. Marx aimed to reveal the economic patterns underpinning the capitalist mode of production in contrast to classical political economists such as Adam Smith, Jean-Baptiste Say, David Ricardo and John Stuart Mill. While Marx did not live to publish the planned second and third parts, they were both completed from his notes and published after his death by his colleague Friedrich Engels. Das Kapital is the most cited book in the social sciences published before 1950.
