Thomas Hodgskin (1787 - 1869) was an English socialist writer on political economy, critic of capitalism and defender of free trade and early trade unions. He used Ricardo's labour theory of value to denounce the appropriation of the most part of value produced by the labour of industrial workers as illegitimate. He propounded these views in a series of lectures at the London Mechanics Institute (later renamed Birkbeck, University of London) where he debated with William Thompson, with whom he shared the critique of capitalist expropriation but not the proposed remedy. The results of these lectures and debates he published as "Labour Defended against the Claims of Capital" (1825), "Popular Political Economy" (1827) and "Natural and Artificial Right of Property Contrasted" (1832). The title of "Labour Defended" was a jibe at James Mill's earlier "Commerce Defended" and signalled his opposition to the latter taking sides with the capitalists against their employees. Despite his high profile in the agitated revolutionary times of the 1820s, he retreated into the realm of Whig journalism after the Reform Act 1832. He became an advocate of free trade and spent 15 years writing for The Economist. He worked on the paper with its founder, James Wilson, and with the young Herbert Spencer. Hodgskin viewed the demise of the Corn Laws as the first step to the downfall of government, and his libertarian anarchism was regarded as too radical by many of the liberals of the Anti-Corn Law League. He left The Economist in 1857, but continued working as a journalist for the rest of his life.
