Russian literary theorist and philosopher of language whose wide-ranging ideas significantly influenced Western thinking in cultural history, linguistics, literary theory, and aesthetics.

After graduating from the University of St. Petersburg (now St. Petersburg State University) in 1918, Bakhtin taught high school in western Russia before moving to Vitebsk (now Vitsyebsk, Belarus), a cultural centre of the region, where he and other intellectuals organized lectures, debates, and concerts. There Bakhtin began to write and develop his critical theories. Because of Stalinist censorship, he often published works under the names of friends, including P.N. Medvedev and V.N. Voloshinov. These early works include Freydizm (1927; Freudianism); Formalny metod v literaturovedeni (1928; The Formal Method in Literary Scholarship), an attack on the Formalist (Formalism)s' view of history; and Marksizm i filosofiya yazyka (1929; Marxism and the Philosophy of Language). Despite his precautions, Bakhtin was arrested in 1929 and exiled to the Kazakh Autonomous Soviet Socialist Republic. From 1945 to 1961 he taught at the Mordovian Teachers Training College.

Bakhtin is especially known for his work on the Russian writer Fyodor Dostoyevsky (Dostoyevsky, Fyodor), Problemy tvorchestva Dostoyevskogo (1929; 2nd ed., 1963, retitled Problemy poetiki Dostoyevskogo; Problems of Dostoevsky's Poetics), which he published under his own name just before he was arrested. It is considered one of the finest critical works on Dostoyevsky. In the book Bakhtin expressed his belief in a mutual relation between meaning and context involving the author, the work, and the reader, each constantly affecting and influencing the others, and the whole influenced by existing political and social forces. Bakhtin further developed this theory of polyphony, or “dialogics,” in Voprosy literatury i estetiki (1975; The Dialogic Imagination), in which he postulated that, rather than being static, language evolves dynamically and is affected by and affects the culture that produces and uses it. Bakhtin also wrote Tvorchestvo Fransua Rable i narodnaya kultura srednevekovya i Renessansa (1965; Rabelais and His World).
