Fredric Jameson (b. 1934) was the leading Marxist literary and cultural critic in the United States and, arguably, in the English-speaking world in the late 20th century and remains so in the early 21st. In a career that spans more than 60 years, Jameson has produced some 25 books and hundreds of essays in which he has demonstrated the versatility and power of Marxist criticism in analyzing and evaluating an enormous range of cultural phenomena, from literary texts to architecture, art history, cinema, economic formations, psychology, social theory, urban studies, and utopianism, to mention but a few. In his early work, Jameson introduced a number of important 20th-century European Marxist theorists to American audiences, beginning with his study of Jean-Paul Sartre’s style and continuing with his Marxism and Form (1971) and The Prison-House of Language (1972), which offered critical analyses of such theorists as Georg Lukacs, Ernst Bloch, Walter Benjamin, and Herbert Marcuse, along with the Frankfurt School, Russian formalism, and French structuralism. With The Political Unconscious (1981) and other works, Jameson deftly articulated such topics as the linguistic turn in literature and philosophy, the concepts of desire and national allegory, and the problems of interpretation and transcoding in a decade when continental theory was beginning to transform literary studies in the English-speaking world. Jameson then became the leading theorist and critic of postmodernism, and his Postmodernism, or, the Cultural Logic of Late Capitalism (1991) demonstrated the power of Marxist theoretical practice to make sense of the system underlying the discrete and seemingly unrelated phenomena in the arts, architecture, media, economics, and so on. Jameson’s concept of cognitive mapping has been especially influential on cultural theories of postmodernity and globalization. Jameson’s lifelong commitment to utopian thought and dialectical criticism have found more systematic expression in such books as Archaeologies of the Future (2005) and Valences of the Dialectic (2009), and he has continued to develop a major, six-volume project titled “The Poetics of Social Forms” (the final two volumes of which remain forthcoming as of 2018), whose trajectory ultimately covers myth, allegory, romance, realism, modernism, postmodernism, and beyond. Jameson’s expansive, eclectic, and ultimately holistic approach to cultural critique demonstrates the power of Marxist critical theory both to interpret, and to help change, the world.
