Kenneth Duva Burke (May 5, 1897 – November 19, 1993) was an American literary theorist, poet, essayist, and novelist, who wrote on 20th-century philosophy, aesthetics, criticism, and rhetorical theory. As a literary theorist, Burke was best known for his analyses based on the nature of knowledge. He was one of the first theorists to stray from more traditional rhetoric and view literature as "symbolic action." Wikipedia
