Everett Hall Everett Wesley Hall (April 24, 1901 – June 17, 1960) was an American philosopher, known for his advocacy of common-sense realism and his notion of what he called the "categorial" primacy of certain assertions. Hall received his A.B. and M.A. degrees from Lawrence College, and his Ph.D. from Cornell University (in 1929). Between 1929 and his death in 1960, he taught at the following universities: the University of Chicago, Ohio State, Stanford, the University of Iowa, and the University of North Carolina (he was Department Chairman at the last two schools and was Kenan Professor at North Carolina). He also held visiting appointments at Northwestern University, the University of Southern California, and Kyoto University. Hall was the author of four books as well as numerous papers. The books are "What is Value" (1952), "Modern Science and Human Values"(1956), "Philosophical Systems"(1960), and "Our Knowledge of Fact and Value" (1961). After his death a number of his papers were collected by his colleague, E. M. Adams and published as "Categorial Analysis" (1964).
