Ludwig Wittgenstein has captured the popular imagination as the modern Socrates, the fascinating master of enigmatic logic. He is an icon of modernism, but what did he really say? In Introducing Wittgenstein we meet a strange man, a rigorous logician who prized poetry above philosophy, who inherited a fortune and gave it away, who sought death in the trenches of the First World War, a great teacher who advised his students to give up philosophy, a solitary man who nonetheless inspired lifelong friendships. We are also given a clear and accessible guide to Wittgenstein's central work, the Tractatus Logico-Philosophicus, a glacier of logic, and his later, friendlier Philosophical Investigations. Here is an accessible introduction for anyone baffled by the complexity or intrigued by the reputation of this great 20th-century philosopher.
