 It is for his metaphysics that Bradley has become best known. He argued that our everyday conceptions of the world (as well as those more refined ones common among his philosophical predecessors) contain hidden contradictions which appear, fatally, when we try to think out their consequences. In particular, Bradley rejected on these grounds the view that reality can be understood as consisting of many objects existing independently of each other (pluralism) and of our experience of them (realism). Consistently, his own view combined substance monism — the claim that reality is one, that there are no real separate things — with metaphysical idealism — the claim that reality consists solely of idea or experience. This vision of the world had a profound effect on the verse of T.S. Eliot, who studied philosophy at Harvard and wrote a Ph.D. thesis on Bradley.
