G. E. Moore

Lore & Background

George Edward Moore was born in Upper Norwood, London, on 4 November 1873, the middle child of seven. He was educated at Dulwich College and began attending Trinity College, Cambridge in 1892, where he studied classics and moral sciences, achieving a double first. He became a Fellow of Trinity in 1898 and later served as Professor of Mental Philosophy and Logic at Cambridge from 1925 to 1939.

Moore was a member of the secretive Cambridge Apostles from 1894 to 1901, where fellow member Bertrand Russell wrote that he 'almost worship him as if he were a god.' He traveled to Norway in 1914 to visit Wittgenstein, taking notes later published as Notes dictated to G.E. Moore in Norway. He was chairman of the Aristotelian Society from 1918 to 1919, a fellow of the British Academy from 1918, and chairman of the Cambridge University Moral Sciences Club from 1912 to 1944. A humanist, he presided over the British Ethical Union in 1935–1936. He was appointed to the Order of Merit in 1951, awarded by King George VI.

Moore is best known for his work Principia Ethica and essays such as 'The Refutation of Idealism,' 'A Defence of Common Sense,' and 'A Proof of the External World.' He argued that 'good' is indefinable and a non-natural property, and that ethical arguments can suffer from the naturalistic fallacy. He died in England on 24 October 1958 and was cremated at Cambridge Crematorium.

Reader's Guide

Moore's significance lies in his role as a founder of analytic philosophy, shifting British philosophy away from idealism toward common-sense realism. His ethical non-naturalism, articulated in Principia Ethica, argued that 'good' is a simple, indefinable, non-natural property, and that attempts to define it commit the naturalistic fallacy. The open-question argument, presented in §13 of that work, contends that any analysis of value fails because questions like 'Is it good that x is pleasant?' remain open and significant. Moore also emphasized moral intuitions as self-evident propositions, leading later writers to label him an ethical intuitionist, though he distinguished his view from earlier intuitionism.

His essays are noted for clarity and methodical treatment of philosophical problems. He was critical of modern philosophy's lack of progress compared to the natural sciences. Moore influenced the Bloomsbury Group but abstained from it, and was described by Ray Monk as 'the most revered philosopher of his era.' Despite his contemporary fame, he is now mostly known among academic philosophers. His legacy includes the paradox that bears his name and his defense of common sense as a philosophical method.
