Sir Michael Anthony Eardley Dummett (ˈdʌmɪt; 27 June 1925 – 27 December 2011) was an English academic described as "among the most significant British philosophers of the last century and a leading campaigner for racial tolerance and equality." He was, until 1992, Wykeham Professor of Logic at the University of Oxford. He wrote on the history of analytic philosophy, notably as an interpreter of Frege, and made original contributions particularly in the philosophies of mathematics, logic, language and metaphysics. He was known for his work on truth and meaning and their implications to debates between realism and anti-realism, a term he helped to popularize. He devised the Quota Borda system of proportional voting, based on the Borda count. In mathematical logic, he developed an intermediate logic, already studied by Kurt Gödel: the Gödel–Dummett logic.
Born 27 June 1925 at his parents' house, 56, York Terrace, Marylebone, London, Dummett was the son of George Herbert Dummett (1880 – 12 November 1969), later of Shepherd's Cottage, Curridge, Berkshire, a silk merchant and rayon dealer, and Mabel Iris (1893–1980), daughter of the civil servant and conservationist Sir Sainthill Eardley-Wilmot (himself grandson of the politician Sir John Eardley-Wilmot, 1st Baronet). He studied at Sandroyd School in Wiltshire, at Winchester College as a scholar, and at Christ Church, Oxford, which awarded him a major scholarship in 1943. He was called up for military service that year and served until 1947, first as a private in the Royal Artillery, then in the Intelligence Corps in India and Malaya. In 1950 he graduated with a first in Politics, Philosophy and Economics from Oxford and was elected a Prize Fellow of All Souls College, Oxford.
In 1979, Dummett became Wykeham Professor of Logic at Oxford, a post he held until retiring in 1992. During his term as Wykeham Professor, he held a Fellowship at New College, Oxford. He has also held teaching posts at Birmingham University, UC Berkeley, Stanford University, Princeton University, and Harvard University.
