The volume tries to offer a comparison between two philosophers who belong to two different philosophical traditions and who have thus been rarely discussed together: Karl Marx and Ludwig Wittgenstein. Despite these thinkers' many distinctions, the contributions to the current volume try to reconstruct not only how the 'second' Wittgenstein was influenced by the Marxist tradition, but also - and above all - the theoretical affinities between the two philosophers. In this way, the book underlines the potential that Marx's political thought holds for philosophers of language as well as the social implications of Wittgenstein's thought and the political potential of some of his central topics, such as his critique of the private language argument and his theory of language games.
