These sixteen original essays, whose authors include some of the world's leading philosophers, examine themes from the work of the Cambridge philosopher G. E. Moore (1873-1958), and demonstrate his considerable continuing influence on philosophical debate. Part I bears on epistemological topics, such as scepticism about the external world, the significance of common sense, and theories of perception. Part II is devoted to themes in ethics, such as Moore's open question argument, his non-naturalism, utilitarianism, and his notion of organic unities.

These thirteen original essays, whose authors include some of the world's leading philosophers, examine themes from the work of the Cambridge philosopher G. E. Moore (1873-1958), and demonstrate his considerable continuing influence on philosophical debate. Part I bears on epistemological topics, such as scepticism about the external world, the significance of common sense, and theories of perception. Part II is devoted to themes in ethics, such as Moore's open question argument, his non-naturalism, utilitarianism, and his notion of organic unities.

Does scepticism threaten our common sense picture of the world? Does it really undermine our deep-rooted certainties? Answers to these questions are offered through a comparative study of the epistemological work of two key figures in the history of analytic philosophy, G. E. Moore and Ludwig Wittgenstein.

Canonized as the "plain man's philosopher" and the "defender of common sense," G. E. Moore is one of the most influential philosophers of the twentieth century. But Moore's role as Bloombury's prophet has remained a mystery. How could the "plain man's philosopher" influence those legendary members of the Bloomsbury group--Lytton Strachey and John Maynard Keynes, for example--who could never be characterized as plain men? With this book, well-known contemporary philosopher Tom Regan solves the mystery. Relying on Moore's published and unpublished work, Regan traces the development of Moore's moral philsophy up to and through his seminal work, Principa Ethica (1903). Regan offers a radical reinterpretation of Principa. Contrary to the standard interpretation, that work's central theme is the liberation of the individual, not dreary conformity to the rules of conventional morality. The Bloomsberries lived Moore's philosophy--the same philosophy subsequent generations have misunderstood. At once literary and scholarly, Bloomsbury's Prophet challenges received opinions not only about Principa and Moore but about Bloomsbury itself.

This edition of G. E. Moore's notes taken at Wittgenstein's seminal Cambridge lectures in the early 1930s provides, for the first time, an almost verbatim record of those classes. The presentation of the notes is both accessible and faithful to their original manuscripts, and a comprehensive introduction and synoptic table of contents provide the reader with essential contextual information and summaries of the topics in each lecture. The lectures form an excellent introduction to Wittgenstein's middle-period thought, covering a broad range of philosophical topics, ranging from core questions in the philosophy of language, mind, logic, and mathematics, to illuminating discussions of subjects on which Wittgenstein says very little elsewhere, including ethics, religion, aesthetics, psychoanalysis, and anthropology. The volume also includes a 1932 essay by Moore critiquing Wittgenstein's conception of grammar, together with Wittgenstein's response. A companion website offers access to images of the entire set of source manuscripts.

Metaethics, understood as a distinct branch of ethics, is often traced to G. E. Moore's 1903 classic, Principia Ethica. Whereas normative ethics is concerned to answer first order moral questions about what is good and bad, right and wrong, metaethics is concerned to answer second order non-moral questions about the semantics, metaphysics, and epistemology of moral thought and discourse. Moore has continued to exert a powerful influence, and the sixteen essays here (most of them specially written for the volume) represent the most up-to-date work in metaethics after, and in some cases directly inspired by, the work of Moore.

The main stream of academic philosophy, in Anglophone countries and increasingly worldwide, is identified by the name 'analytic'. The study of its history, from the 19th century to the late 20th, has boomed in recent years. These specially commissioned essays by forty leading scholars constitute the most comprehensive book on the subject.
