A Defense of Realism

Book excerpt: English philosopher George Edward Moore (1873-1958) developed the chief modern theory of ethics, Ideal Utilitarianism. A Defense of Realism examines Moore's conception of philosophy and his views on the importance of metaphysics, presenting and evaluating the Principia Ethica author's criticisms and refutations of certain philosophical positions, especially idealism, naive realism, phenomenalism, and pragmatism. Klemke gives a detailed analysis and an appraisal of Moore's defense of common sense, and concentrates on Moore's realism, beginning with the reality of entities in the natural universe, and proofs of the external world. Finally, Klemke analyzes and enhances through personal argument Moore's views on the reality of various nonnatural entities crucial to Moore's defense of philosophical realism.
