Chisholm, Roderick Milton (1916–1999)

Chisholm was an important analytic philosopher of the second half of the twentieth century. His work in epistemology, metaphysics and ethics is characterized by scrupulous attention to detail, the use of a few basic, undefined or primitive terms, and extraordinary clarity. One of the first Anglo-American philosophers to make fruitful use of Brentano and Meinong, Chisholm translated many of Brentano’s philosophical writings. As one of the great teachers, Chisholm is widely known for the three editions of Theory of Knowledge, a short book and the standard text in US graduate epistemology courses. An ontological Platonist, Chisholm defends human free will and a strict sense of personal identity.
