Alfred Cyril Ewing (Leicester, May 11, 1899 - Manchester, May 14, 1973) was a British philosopher and a sympathetic critic of Idealism.
Ewing studied at Oxford, where he gained the John Locke Lectureship and the Green Prize in Moral Philosophy. He taught for four years in Swansea/Wales, and became lecturer in Moral Science at Cambridge in 1931, based at Trinity Hall, and reader in Moral Science in 1954. He was a Honorary Fellow of Jesus College, Cambridge, and one of Wittgenstein's foremost critics. He was responsible for Karl Popper's invitation to Cambridge.
Ewing believed that the study of the history of philosophy was important to philosophical practice, and paid particular attention to this in his studies of Kant.
He was a defender of metaphysics and developed what may be termed an 'analytical idealism'. He was a 20th century pioneer in the philosophy of religion, one of the foremost analysts of the concept "good," and a distinguished contributor to justificatory theorizing about punishment.
He was president of the Aristotelian Society from 1941 to 1942 and was made a Fellow of the British Academy in 1941.
