Sixty years after its first edition, there is an increasing consensus among scholars that the work posthumously published as Philosophical Investigations represents something that is far from a complete picture of Wittgenstein’s second book project. G.H. von Wright’s seminal research on the Nachlass was an important contribution in this direction, showing that the Wittgenstein papers can reveal much more than the source of specific remarks. This book specifically explores Wittgenstein’s Philosophical Investigations from the different angles of its originary conceptions, including the mathematical texts, shedding new light on fundamental issues in twentieth century and contemporary philosophy. Leading authorities in the field focus on newly published or hitherto unpublished sources for the interpretation of Wittgenstein’s later work and a Wittgenstein typescript, translated for the first time into English, is included as an appendix.

Incorporating significant editorial changes from earlier editions, the fourth edition of Ludwig Wittgenstein's Philosophical Investigations is the definitive en face German-English version of the most important work of 20th-century philosophy The extensively revised English translation incorporates many hundreds of changes to Anscombe’s original translation Footnoted remarks in the earlier editions have now been relocated in the text What was previously referred to as ‘Part 2’ is now republished as Philosophy of Psychology – A Fragment, and all the remarks in it are numbered for ease of reference New detailed editorial endnotes explain decisions of translators and identify references and allusions in Wittgenstein's original text Now features new essays on the history of the Philosophical Investigations, and the problems of translating Wittgenstein’s text

First published in 1992. Although there is a vast amount of secondary literature on the Philosophical Investigations, very little exists which considers the exegesis of this important text. The apparently disjointed structure of the book has often been taken as a licence for interpreting passages out of context. This collection shows how important it is to consider the arguments which specify or authorise particular readings of certain passages. The essays are by distinguished Wittgenstein scholars. All approach the Investigations with the conviction that prior to pronouncements of the relevance or tenability of certain remarks one must always carefully consider Wittgenstein's text itself and locate the puzzling passages in their (immediate or original) contexts. Diverse exegetical approaches are represented; while some believe that the Investigations can be read as an independent text, others find it essential to look at the context of a particular remark, or of variations on it, in Wittgenstein's other texts. A lively debate emerges as authors differ in their assessment of the philosophical value of their material; some try to show that careful interpretations reveal valuable insights into prima facie untenable passages, others conclude that certain remarks fail to resolve the issues they address. This is the first strictly exegetical collection of papers on the Investigations. It is a major contribution to the study of not only this work, but of Wittgenstein's thought and an important strand of twentieth century philosophy.

The Philosophical Investigations of Ludwig Wittgenstein (1889–1951) present his own distillation of two decades of intense work on the philosophies of mind, language and meaning.

First Published in 2004. One of the greatest works of twentieth-century philosophy, Ludwig Wittgenstein’s Philosophical Investigations is also one of the most controversial. Wittgenstein’s Investigations 1–133 provides a clear and concise introduction to the crucial early sections of this classic work. Andrew Lugg discusses in detail what Wittgenstein says about meaning, metaphysics and philosophy in sections 1–133 of the Philosophical Investigations. Besides making Wittgenstein’s thought accessible to a general audience and explaining its philosophical significance, the book develops a radical interpretation of his remarks. It takes Wittgenstein’s text to epitomize his philosophical outlook and applies Wittgenstein’s philosophical strategy to his own words. Wittgenstein’s Investigations 1–133 will be a valuable resource for anyone interested in Wittgenstein, language and the history of twentieth□century philosophy

Wittgenstein: Meaning and Mind is the third volume of a four-volume analytical commentary on Wittgenstein's Philosophical Investigations, consisting of two parts. Part 1 is a sequence of fifteen essays that examine in detail all the major topics discussed in Philosophical Investigations §§243-427. These include the private language arguments, privacy, private ostensive definition, the nature of the mind, the inner and the outer, behaviour and behaviourism, thought, imagination, the self, consciousness, and criteria. Published in 1990 to widespread acclaim as a scholarly tour de force, the first edition of this volume of essays provides a comprehensive survey of these themes, the history of their treatment in early modern and modern philosophy, the development of Wittgenstein's ideas on these subjects from 1929 onwards, and an elaborate analysis of his definitive arguments in the Investigations. The new second edition has been thoroughly revised by the author and features four new essays. These include a survey of the evolution of the private language arguments in Wittgenstein's oeuvre and their role within the developing argument of the Investigations, a comprehensive essay on private ownership of experience and its pitfalls, a detailed examination and defence of Wittgenstein's repudiation of subjective knowledge of one's experience, and an overview of the achievement and importance of the private language arguments. Revised essays examine new objections to Wittgenstein's arguments – which are found wanting– and incorporate new materials from the Nachlass that were not known to exist in 1990. All references have been adjusted to the revised fourth edition of the Investigations, but previous pagination in the first and second editions has been retained in parentheses. These revisions bring the book up to the high standard of the extensively revised editions of Wittgenstein: Understanding and Meaning (Blackwell, 2005) and Wittgenstein: Rules, Grammar and Necessity (Wiley Blackwell, 2009). They ensure that this survey of Wittgenstein's private language arguments and of his accounts of thought, imagination, consciousness, the self, and criteria will remain the essential reference work on the Investigations for the foreseeable future.

Wittgenstein: Meaning and Mind, Part 2 – Exegesis §§243-427 explores and clarifies the patterns, developments, and conclusions of Wittgenstein’s arguments in §§243-427 of Philosophical Investigations. Each numbered remark in Wittgenstein’s text is systematically analysed. Problematic expressions, phrases and sentences are clarified, source remarks in Wittgenstein’s Nachlass that shed light on the text are elaborated. The bearing of the remarks on deep philosophical problems is made clear. This volume of exegesis of §§243-427 has been extensively revised, incorporating numerous references to original and secondary texts of Wittgenstein that were not known to exist in 1990. New comprehensive tables of correlation between the remarks of the Investigations and the source of the remarks in the Nachlass have been added. A variety of controversies of the last quarter of a century concerning the private language arguments, the nature of thought and imagination, consciousness and the self are addressed and settled explicitly or implicitly in the new exegesis. All references to Wittgenstein’s text have been adjusted to the fourth edition, although page references to the first and second editions have been retained in parenthesis. These revisions bring the book up to the high standard of the extensively revised editions of Wittgenstein: Understanding and Meaning (2005) and Wittgenstein: Rules, Grammar and Necessity (2009). They ensure that this survey of Investigations §§243-427 will remain the essential reference work on Wittgenstein’s masterpiece for the foreseeable future.

This is a new edition of the first volume of G.P.Baker and P.M.S. Hacker’s definitive reference work on Wittgenstein’s Philosophical Investigations. Takes into account much material that was unavailable when the first edition was written. Following Baker’s death in 2002, P.M.S. Hacker has thoroughly revised the first volume, rewriting many essays and sections of exegesis completely. Part One – the Essays – now includes two completely new essays: 'Meaning and Use' and 'The Recantation of a Metaphysician'. Part Two – Exegesis §§1–184 – has been thoroughly revised in the light of the electronic publication of Wittgenstein’s Nachlass, and includes many new interpretations of the remarks, a history of the composition of the book, and an overview of its structure. The revisions will ensure that this remains the definitive reference work on Wittgenstein’s masterpiece for the foreseeable future.
