Robert Boyce Brandom (born March 13, 1950) is an American philosopher who teaches at the University of Pittsburgh. He works primarily in philosophy of language, philosophy of mind and philosophical logic, and his academic output manifests both systematic and historical interests in these topics. His work has presented "arguably the first fully systematic and technically rigorous attempt to explain the meaning of linguistic items in terms of their socially norm-governed use ("meaning as use", to cite the Wittgensteinian slogan), thereby also giving a non-representationalist account of the intentionality of thought and the rationality of action as well."
