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.

The volume is full of thought-provoking insight which will prove a stimulus both to further study and to scholarly disagreement.

Rush Rhees, a close friend of Wittgenstein and a major interpreter of his work, shows how Wittgenstein's On Certainty concerns logic, language, and reality – topics that occupied Wittgenstein since early in his career. Authoritative interpretation of Wittgenstein's last great work, On Certainty, by one of his closest friends. Debunks misconceptions about Wittgenstein's On Certainty and shows that it is an essay on logic. Exposes the continuity in Wittgenstein's thought, and the radical character of his conclusions. Contains a substantial and illuminating afterword discussing current scholarship surrounding On Certainty, and its relationship to Rhees's work on this subject.

Ludwig Wittgenstein is arguably the most important philosopher of the twentieth century. In On Certainty he discusses central issues in epistemology, including the nature of knowledge and scepticism. The Routledge Philosophy Guidebook to Wittgenstein and On Certainty introduces and assesses: Wittgenstein's career and the background to his later philosophy the central ideas and text of On Certainty, including its responses to G.E. Moore and discussion of fundamental issues in the theory of knowledge Wittgenstein's continuing importance in contemporary philosophy. This GuideBook is essential reading for all students of Wittgenstein, and for those studying epistemology and philosophy of language. On Certainty, Wittgenstein's final work, addresses a category of "world-picture" propositions discovered by G.E. Moore. These challenge Wittgenstein's enduring commitment to a well-defined category of empirical propositions, and help to generate a critique of scepticism. Developing Wittgenstein's view that scepticism is self-undermining, the Guidebook offers a combative yet therapeutic interpretation that locates On Certainty between the standpoints of Kant and Hume.

This is the first collection of papers devoted to Ludwig Wittgenstein's cryptic but brilliant, On Certainty . This work, Wittgenstein's last, extends the thinking of his earlier, better known writings, and in so doing, makes the most important contribution to epistemology since Kant's Critique of Pure Reason - a claim the essays in this volume help to demonstrate. The essays have been grouped under four headings, reflecting current approaches to the work: the Framework, Transcendental, Epistemic, and Therapeutic readings.

This book sheds unprecedented light on Wittgenstein's third masterpiece, On Certainty , clarifying his thoughts on basic beliefs and rebuttal of scepticism. As an introduction and commentary on Wittgenstein's final major philosophical work, Moyal-Sharrock's book will prove an indispensable guide to the student, scholar and general reader.

Written over the last 18 months of his life and inspired by his interest in G. E. Moore's defence of common sense, this much discussed volume collects Wittgenstein's reflections on knowledge and certainty, on what it is to know a proposition for sure.
