In the late 19th and early 20th centuries, Gertrude Buck and collaborators developed a sociologicallyand pragmatist-informed approach to language that has been neglected in later scholarship. Buck approached the study of language from the standpoint of pragmatist functional psychology, which is indebted to John Dewey's pragmatism at the University of Michigan, and which views language as a normal, dynamic action of human organisms engaged in necessary cooperative relations with one another. Her approach overcomes the small-minded pragmatism that would criticize figurative or poetic language as impractical, and instead shows how figuration is essential to the particular ways in which language is action that conveys meaning to others and serves broader social functions. Buck's forgotten work helps overcome criticisms of the application of pragmatic action theory to language and literature, sketching how language structure may be explained on the basis of language as a natural social-communicative act, how figurative language is inherent in the normal act of communicating situated bodily experiences to others, and how rhetorical speech and writing contributes to participation in democratic social processes. This paper also indicates how Buck's work has been partially rediscovered in Composition Studies, as well as prefigures later reader-response esthetics and feminist analyses of language.
