Dummett was born in 1925. In 1944 he was received into the Roman Catholic Church, and remains a practising Catholic. He studied at Christ Church College, Oxford, and was awarded a fellowship at All Souls College. In 1979, he became Wykeham Professor of Logic at Oxford, which a post he held until retiring in 1992. He received a Knighthood in 1999.
His work on the German philosopher Frege has also been acclaimed. His first book Frege: Philosophy of Language (1973), written over many years, is now regarded as a classic. The book was instrumental in the rediscovery of Frege's work, and influenced a whole generation of British philosophers, including Gareth Evans.
In his paper Realism he popularised the term anti-realism, used to describe any position involving either the denial of the objective reality of entities of a certain type or the insistence that we should be agnostic about their real existence. Thus, we may speak of anti-realism with respect to other minds, the past, the future, universals, mathematical entities (such as natural numbers), moral categories, the material world, or even thought.
