Critique of Political Economy") was published on 14 September 1867, dedicated to Wilhelm Wolff and was the sole volume published in Marx’s lifetime. "Capital, Volume II", subtitled "The Process of Circulation of Capital", was prepared by Engels from notes left by Marx and published in 1885. It is divided into three parts: "The Metamorphoses of Capital and Their Circuits", "The Turnover of Capital" and "The Reproduction and Circulation of the Aggregate Social Capital". In "Volume II", the
Karl Marx value advocated by David Ricardo. The work was enthusiastically received, and the edition sold out quickly. The successful sales of "A Contribution to the Critique of Political Economy" stimulated Marx in the early 1860s to finish work on the three large volumes that would compose his major life's work – "Das Kapital" and the "Theories of Surplus Value", which discussed the theoreticians of political economy, particularly Adam Smith and David Ricardo. "Theories of Surplus Value" is often referred to as the fourth volume of "Das Kapital" and constitutes one of the first comprehensive treatises on the history of economic thought.
