born June 27, 1925, London, Eng.
British philosopher.
Dummett has done influential work in the philosophy of language, metaphysics, logic, and the philosophy of mathematics; he is also one of the foremost expositors of the work of Gottlob Frege . He is known chiefly for his defense of antirealism (see realism ) and his attempt to explicate sentence meaning in terms of "assertibility conditions" rather than truth conditions. His major works include Frege: Philosophy of Language (1973), Truth and Other Enigmas (1978), The Logical Basis of Metaphysics (1991), and The Seas of Language (1993)
