Forming a triangle of British empiricism with Locke and Hume, George Berkeley's direct influence on modern thought cannot be overstated. From the American Founding Fathers, who looked to him as the pioneer of their idealism, to the reality-questioning motives of quantum physics, Berkeley's odd yet profound view of the nature of human awareness, a sense he trusted implicitly, has in turn shaped our perception of the universe at large. His 1709 "Essay Towards a New Theory of Vision" reads like the ramblings of a madman-and he was, in fact, dismissed as such in his time-but his discussion of perception, distance, parallelism, magnitude, and other elements of vision, presented as 160 suppositions, is now recognized as a foundational work on the theory of optics. This strange work will intrigue readers of philosophy and scientific theory. Irish scientist, philosopher, and writer GEORGE BERKELEY (1685-1753) also wrote A Treatise Concerning the Principles of Human Knowledge (1710) and Three Dialogues Between Hylas and Philonous (1713).

Born and reared in Ireland, George Berkeley studied at Trinity College, Dublin, and then taught as a fellow there, eventually becoming Dean of Derry (1724) and Bishop of Cloyne (1734) in the Irish branch of the Anglican church. His primary philosophical interests included metaphysics and epistemology, the psychology of perception, philosophy of science, and natural theology. But he is best known for his defense of metaphysical idealism and denial of the existence of matter. Berkeley's best-known writings were produced relatively early in his life, between the ages of 24 and 28: They included Essay Towards a New Theory of Vision (1709), Treatise Concerning the Principles of Human Knowledge (1710), and Three Dialogues (1713). In 1728 Berkeley made a voyage to the United States in an unsuccessful attempt to found a college in Bermuda. He lived for two years at Newport, Rhode Island, and had a significant influence on American education, chiefly through his association with and donation of books to Yale University and his correspondence with Samuel Johnson, the first president of what is now Columbia University.
