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" aims to provide a clear and concise introduction to the early sections of this book. The author discusses in detail Wittgenstein's remarks on meaning, metaphysics and philosophy. He considers each section in detail clarifying their philosophical significance in a manner accessible to the general reader. The book acts not only as a scholarly introduction to "Philosophical Investgations" but also draws attention to Wittgenstein's philosophical outlook by applying the same strategy to his text.
