George Edward Moore (1873–1958) successfully revived epistemological and metaphysical realism and supported a common sense philosophical method. He spent most of his career at Cambridge University, becoming a professor there in 1925. As an undergraduate, Moore was a member of the Cambridge Apostles, a select intellectual group of Cambridge University undergraduates. He was editor of the top analytic journal, Mind (1921–1947). Moore’s main books are Philosophical Studies (1922), Principia Ethica (1903), and Some Main Problems of Philosophy (1953).
