Dummett, Sir Michael A(nthony) E(ardley)

(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).
