Keynes and philosophers

Abstract

CAMBRIDGE PHILOSOPHERS AND EARLY BELIEFS In 1903, Cambridge saw the launching of three seminal works that would exercise a powerful impact on twentieth-century philosophy: G. E. Moore's Principia Ethica and Refutation of Idealism , and Bertrand Russell's Principles of Mathematics . It was natural for a sophisticated and ambitious freshman in mathematics, the son of a lecturer in moral science, to plunge into animated philosophical debates. Keynes attended Moore's lectures on ethics and McTaggart's on metaphysics, also becoming an active member of the Apostles Society, of which the three elder philosophers were leading figures. While still an undergraduate student, Keynes wrote papers on ethics, aesthetics and metaphysics and in 1907 completed the fellowship dissertation, later expanded into A Treatise on Probability . It is generally agreed that Principia Ethica was ‘the book’ the young Keynes ‘grew up under’, as he himself recollected in the autobiographical Memoir read in 1938 at a meeting of Bloomsbury, the London group that was heir to the Cambridge Apostles. On that occasion, he gave a lively and passionate picture of the Moorian dispensation of love, beauty and truth, conceived as Platonic ideas and representing the greatest incarnation of the good, embodied in subjective mental states of personal affection and aesthetic enjoyment. This ‘religion’, Keynes said, fitted ‘the undisturbed individualism which was the extraordinary achievement of the early Edwardian days’ (JMK X: 444).
