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.

There could be no better introduction to Wittgenstein's thought than the Blue Book, whose simplicity and forthrightness must make an instant appeal. The progressive complications of the Brown Book make a natural bridge to the still more subtle, but often confusing, exposition of the Investigations.

Hacker Immediately upon its posthumous publication in 1953, Ludwig Wittgenstein’s Philosophical Investigations was hailed as a masterpiece, and the ensuing years have confirmed this initial assessment. Today it is widely acknowledged to be the single most important philosophical work of the twentieth century. In this definitive new en face German-English edition, Wittgenstein experts Peter Hacker and Joachim Schulte have incorporated significant editorial changes to earlier editions of Philosophical Investigations in order to reflect more closely Wittgenstein’s original intentions. Notable revisions include the placement of Wittgenstein’s notes – Randbemerkungen – into their designated positions in the text, some corrections to the originally published German text, and the numbering of all the remarks in what was called Part 2 and is now named Philosophy of Psychology – A Fragment. Extensive modifications and corrections have also been made to G. E. M. Anscombe’s original English translation. Detailed editorial endnotes have been added to illuminate difficult translation decisions and to identify references and allusions in Wittgenstein’s original text.

Wittgenstein was centrally concerned with the puzzling nature of the mind, mathematics, morality and modality. He also developed innovative views about the status and methodology of philosophy and was explicitly opposed to crudely "scientistic" worldviews. His later thought has thus often been understood as elaborating a nuanced form of naturalism appealing to such notions as "form of life", "primitive reactions", "natural history", "general facts of nature" and "common behaviour of mankind". And yet, Wittgenstein is strangely absent from much of the contemporary literature on naturalism and naturalising projects. This is the first collection of essays to focus explicitly on the relationship between Wittgenstein and naturalism. The volume is divided into four sections, each of which addresses a different aspect of naturalism and its relation to Wittgenstein's thought. The first section considers how naturalism could or should be understood. The second section deals with some of the main problematic domains—consciousness, meaning, mathematics—that philosophers have typically sought to naturalise. The third section explores ways in which the conceptual nature of human life might be continuous in important respects with animals. The final section is concerned with the naturalistic status and methodology of philosophy itself. This book thus casts a fresh light on many classical philosophical issues and brings Wittgensteinian ideas to bear on a number of current debates-for example experimental philosophy, neo-pragmatism and animal cognition/ethics-in which naturalism is playing a central role.

In this new introduction to a classic philosophical text, David Stern examines Wittgenstein's Philosophical Investigations. He gives particular attention to both the arguments of the Investigations and the way in which the work is written, especially the role of dialogue in the book. While he concentrates on helping the reader to arrive at his or h er own interpretation of the primary text, he also provides guidance to the unusually wide range of existing interpretations, and to the reasons why the Investigations have inspired such a diversity of readings.

First published in 1963, Varieties of Goodness presents analysis of the concept of value and its relations with the neighbouring concepts of fact and norm. The author discusses important themes such as instrumental and technical goodness; utilitarian goodness; goodness of faculties; active and passive pleasure; ethical hedonism; ideals of happiness; divisions of the virtues; connection between values and norms; concept of duty; and justice. This is a must read for scholars and researchers of philosophy.
