G.A. Cohen

Gerald Allan Cohen FBA (/ˈkoʊən/; 1941–2009), known as G. A. Cohen or Jerry Cohen, was a Canadian Marxist political philosopher who held the positions of Quain Professor of Jurisprudence, University College London and Chichele Professor of Social and Political Theory, All Souls College, Oxford.

Born into a communist Jewish family in Montreal, Quebec, on 14 April 1941, Cohen was educated at McGill University (BA, philosophy and political science) in his home town and the University of Oxford (BPhil, philosophy) where he studied under Isaiah Berlin and Gilbert Ryle.

Cohen was assistant lecturer (1963–1964), lecturer (1964–1979) then reader (1979–1984) in the Department of Philosophy at University College London, before being appointed to the Chichele chair at Oxford in 1985. Several of his students, such as Christopher Bertram, Simon Caney, Alan Carter, Cécile Fabre, Will Kymlicka, John McMurtry, David Leopold, Michael Otsuka, Seana Shiffrin, and Jonathan Wolff have gone on to be important moral and political philosophers in their own right, while another, Ricky Gervais, has pursued a successful career in comedy.

Known as a proponent of analytical Marxism and a founding member of the September Group, Cohen's 1978 work Karl Marx's Theory of History: A Defence defends an interpretation of Karl Marx's historical materialism often referred to as technological determinism by its critics. In Self-Ownership, Freedom, and Equality, Cohen offers an extensive moral argument in favour of socialism, contrasting his views with those of John Rawls and Robert Nozick, by articulating an extensive critique of the Lockean principle of self-ownership as well as the use of that principle to defend right as well as left libertarianism. In If You're an Egalitarian, How Come You're So Rich? (which covers the topic of his Gifford Lectures), Cohen addresses the question of what egalitarian political principles imply for the personal behaviour of those who subscribe to them.

Cohen was close friends with Marxist political philosopher Marshall Berman.

Cohen died on 5 August 2009.
