"Capital" Taken from the flap of the book: Capital is a critical analysis of capitalism as political economy, and how it is the precursor of the socialist mode of production. Karl Marx proposes that the motivating force of capitalism is in the exploitation of labour, whose unpaid work is the ultimate source of profit and surplus value. The employer can claim right to the profits (new output value), because he or she owns the productive capital assets (means of production), which are legally protected by the State through property rights. In producing capital (money) rather than commodities (goods and services), the workers continually reproduce the economic conditions by which they labour. Capital proposes an explanation of the "laws of motion" of the capitalist economic system, from its origins to its future, by describing the dynamics of the accumulation of capital, the growth of wage labour, the transformation of the workplace, the concentration of capital, commercial competition, the banking system, the decline of the profit rate, and land-rents.
Karl Marx (5 May 1818 – 14 March 1883) was a German philosopher, economist, historian, sociologist, political theorist, journalist and socialist revolutionary. Born in Trier, Germany, Marx studied law and philosophy at university. He married Jenny von Westphalen in 1843. Due to his political publications, Marx became stateless and lived in exile with his wife and children in London for decades, where he continued to develop his thought in collaboration with German thinker Friedrich Engels and publish his writings, researching in the reading room of the British Museum. His best-known titles are the 1848 pamphlet, The Communist Manifesto, and the three-volume Das Kapital. His political and philosophical thought had enormous influence on subsequent intellectual, economic and political history and his name has been used as an adjective, a noun and a school of social theory. Marx's theories about society, economics and politics – collectively understood as Marxism – hold that human societies develop through class struggle. In capitalism, this manifests itself in the conflict between the ruling classes (known as the bourgeoisie) that control the means of production and the working classes (known as the proletariat) that enable these means by selling their labour power in return for wages. Employing a critical approach known as historical materialism, Marx predicted that, like previous socio-economic systems, capitalism produced internal tensions which would lead to its self-destruction and replacement by a new system: socialism. For Marx, class antagonisms under capitalism, owing in part to its instability and crisis-prone nature, would eventuate the working class' development of class consciousness, leading to their conquest of political power and eventually the establishment of a classless, communist society constituted by a free association of producers. Marx actively pressed for its implementation, arguing that the working class should carry out organised revolutionary action to topple capitalism and bring about socio-economic emancipation. Marx has been described as one of the most influential figures in human history, and his work has been both lauded and criticised. His work in economics laid the basis for much of the current understanding of labour and its relation to capital, and subsequent economic thought. Many intellectuals, labour unions, artists and political parties worldwide have been influenced by Marx's work, with many modifying or adapting his ideas. Marx is typically cited as one of the principal architects of modern social science.
