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.
