Ludwig Wittgenstein's Tractatus Logico-Philosophicus (1922) and Philosophical Investigations (1953) are among the most influential philosophical books of the twentieth century, and also among the most perplexing. Wittgenstein warned again and again that he was not and would not be understood. Moreover, Wittgenstein’s work seems to have little relevance to the way philosophy is done today. In Wittgenstein in Exile, James Klagge proposes a new way of looking at Wittgenstein--as an exile--that helps make sense of this.
