Dudley Knowles retired in July 2011 as Professor of Political Philosophy at the University of Glasgow. He studied for his first degree at Bedford College, University of London, graduating in 1970. After a spell managing a hotel in Glencoe, he studied for a two-year thesis (MLitt) at the University of Glasgow, where he was appointed lecturer in 1973. He remained in Glasgow throughout his academic career. Although he has published on a variety of topics, his main interests have been in political philosophy and its history. He has published three books – Political Philosophy(2001), Hegel and The Philosophy of Right (2002) and Political Obligation (2010) – and edited several more. In retirement, he has continued to work on problems associated with political obligation and is preparing a second edition of Political Philosophy. He anticipates working on the nature and value of political freedom in his dotage.
