The Economic Doctrines of Karl Marx Despite Lenin’s denunciation of Kautsky this book was considered such an excellent introduction to the subject of Marxist economics that it was still being used as a text-book at the Lenin School in Moscow in 1931.
[Classics] Anti-Dühring A classic of Marxism, Anti-Dühring was highly recommended by Lenin as a ‘text book’ of scientific socialism. It was originally written as a polemic against Eugen Dühring, a German revisionist who challenged the basic ideas of Marxism by counterposing his own ‘scientific’ theories within the Social Democratic Party of Germany. Very reluctantly, Engels was forced to take up these ideas and in doing so explained in the clearest fashion the revolutionary theories of Marxism.
[Classics] Value, Price and Profit Value, Price and Profit was produced at a time when the labour theory of value had already matured in Marx’s brain. It was first delivered as a speech delivered by Marx to the International Working Men's Association (The First International) in June 1865, while he was working on the first volume of Capital that was published two years later.
[Classics] Preface to A Contribution to the Critique of Political Economy The Preface of the Critique contains the first connected account of one of Marx's main theories: the materialist conception of history. The participants in history may not always be aware of what motives drive them, seeking instead to rationalise them in one way or another, but those motives exist and have a basis in the real world.
[Classics] Wage Labour and Capital Wage Labour and Capital is based on lectures delivered by Marx at the German Workingmen’s Club of Brussels in 1847, that is, before the Communist Manifesto and at a time when Marx had not yet fully developed his theories of political economy. Although it is an early work, Wage Labour and Capital contains the outline of the Labour Theory of Value and many important insights into the workings of the capitalist system and the way in which workers are exploited.
