First published in 1867, Capital, or Das Kapital, is the infamous treatise on economics and capitalism by Prussian revolutionary KARL MARX (1818-1883), who changed history with his 1848 book The Communist Manifesto. In this work, edited by Marx's friend, German philosopher FRIEDRICH ENGELS (1820-1895), Marx systematically analyzes the way the capitalist machine functions. In this academic work written for students and serious thinkers, he explores wages, competition, banking, rent, and the natural laws that seem to govern the development of capitalism without any oversight by the society in which it developed. Originally published in three volumes, Capital is here presented in five volumes. Volume III, Part 2 covers: . Transformation of Surplus Profit into Ground-Rent . The Revenues and Their Sources.
