Volume I is one of the most influential documents of modern times, looking at the relationship between labor and value, the role of money, and the conflict between the classes. The" forgotten" second volume of Capital, Marx's world-shaking analysis of economics, politics, and history, contains the vital discussion of commodity, the cornerstone to Marx's theories. The third volume was unfinished at the time of Marx's death in 1883 and first published with a preface by Frederick Engels in 1894, strove to combine the theories and concepts of the two previous volumes in order to prove conclusively that capitalism is inherently unworkable as a permanent system for society. Here, Marx asserts controversially that-regardless of the efforts of individual capitalists, public authorities or even generous philanthropists-any market economy is inevitably doomed to endure a series of worsening, explosive crises leading finally to complete collapse. But he also offers an inspirational and compelling prediction: that the end of capitalism will culminate, ultimately, in the birth of a far greater form of society.
