A. C. Ewing (1899–1973) came last in the tradition of British moral philosophers that began with Henry Sidgwick and continued with H. A. Prichard, G. E. Moore, W. D. Ross, and C. D. Broad. Philosophers in this tradition shared a nonnaturalist realist view of moral metaphysics and the nature of moral judgment, but they differed on the relations between normative concepts and on normative ethics. Ewing made substantial contributions to these controversies and anticipated several moves in the contemporary debates as he sought to reconcile putatively incompatible views. Attempts to find conciliatory “middle ways” are a recurring theme in Ewing's work. This essay focuses on three main topics: moral metaphysics and the nature of moral judgment, the relation between intrinsic goodness and ought, and utilitarianism and Rossian deontology. Finally, it describes briefly Ewing's work in other areas of moral philosophy.
