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.

Ludwig Wittgenstein's On Certainty was finished just before his death in 1951 and is a running commentary on three of G.E. Moore's greatest epistemological papers. In the early 1930s, Moore had written a lengthy commentary on Wittgenstein, anticipating some of the issues Wittgenstein would discuss in On Certainty. The philosophical relationship between these two great philosophers and their overlapping, but nevertheless differing, views is the subject of this book. Both defended the existence of certainty and thus opposed any form of skepticism. However, their defenses and conceptions of certainty differed widely, as did their understanding of the nature of skepticism and how best to combat it. Stroll's book contains a careful and critical analysis of their differing approaches to a set of fundamental epistemological problems.

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.

G.E. Moore, more than either Bertrand Russell or Ludwig Wittgenstein, was chiefly responsible for the rise of the analytic method in twentieth-century philosophy. This selection of his writings shows Moore at his very best. The classic essays are crucial to major philosophical debates that still resonate today. Amongst those included are: * A Defense of Common Sense * Certainty * Sense-Data * External and Internal Relations * Hume's Theory Explained * Is Existence a Predicate? * Proof of an External World In addition, this collection also contains the key early papers in which Moore signals his break with idealism, and three important previously unpublished papers from his later work which illustrate his relationship with Wittgenstein.

This “wicked, melancholy, and . . . astonishing” novel reimagines the lives of three wildly different men adrift in the 20th century: Ludwig Wittgenstein, Bertrand Russell, and G. E. Moore (Newsday). When Bruce Duffy’s The World As I Found It was first published, critics and readers were bowled over by its daring reimagining of the lives of three very different men, the philosophers Bertrand Russell, G. E. Moore, and Ludwig Wittgenstein. A brilliant group portrait with the vertiginous displacements of twentieth-century life looming large in the background, Duffy’s novel depicts times and places as various as Vienna 1900, the trenches of World War I, Bloomsbury, and the colleges of Cambridge, while the complicated main characters appear not only in thought and dispute but in love and despair. Wittgenstein, a strange, troubled, and troubling man of gnawing contradictions, is at the center of a novel that reminds us that the apparently abstract and formal questions that animate philosophy are nothing less than the intractable matters of life and death.
