Ralph Charles Sutherland Walker is an Emeritus Fellow of Magdalen College, Oxford. An expert on the philosophy of Immanuel Kant, he was a Rhodes Scholar at Balliol College, before entering academia as a fellow at Merton College in 1968. He moved to Magdalen in 1972 (where, for many years, he was Wine Steward), where he has worked ever since. Apart from focusing on Kant, Walker has also made contributions to the Coherence Theory of Truth, and his books have been translated into numerous languages.
