 As Sidgwick’s publications attest, he was not only a pre-eminent moral philosopher, with sophisticated views on both going controversies in ethics and metaethics and the history of these subjects, but also an accomplished epistemologist, classicist, economist, political theorist, political historian, literary critic, parapsychologist, and educational theorist. If he was a founder of the Cambridge school of philosophy, he was also a founder of the Cambridge school of economics (along with his colleague and sometimes nemesis Alfred Marshall) and of the Cambridge school of political theory (along with such colleagues as Browning and Sir John Seeley). If such students as Moore and Russell owed him much, so too did such students and admirers as Balfour, J. N. Keynes, F. W. Maitland, F. Y. Edgeworth, James Ward, Frank Podmore, and E. E. Constance Jones. He had serious interests in many areas of philosophy and theology, and also wrote insightfully about poetry and literature, two of his great loves (at Newnham, he lectured on Shakespeare, along with such subjects as philosophy and economics). Indeed, Sidgwick was a force in the larger cultural developments of his age, active in such influential discussion societies as the Metaphysical Society and the Synthetic Society. His friends included George Eliot, T. H. Green, James Bryce, H. G. Dakyns, Roden Noel, and, of special importance, John Addington Symonds, the erudite cultural historian, poet, and man of letters who was a pioneer in the serious historical study of same sex love (Schultz 2004). Sidgwick’s versatile and many-sided intellect—not to mention his keen wit—are typically better displayed in his essays and letters than in his best-known academic books. He was in fact much loved for his gentle humor (or “Sidgwickedness”) and sympathetic conversation, and his philosophical students prized him for his candor. As Balfour put it: “Of all the men I have known he was the readiest to consider every controversy and every controversialist on their merits. He never claimed authority; he never sought to impose his views; he never argued for victory; he never evaded an issue.” (Sidgwick and Sidgwick, 1906: 311).
