Difficult to know and impossible to forget, Ludwig Wittgenstein is remembered as the greatest philosopher of the twentieth century. He published only one book in his lifetime - a masterpiece that moulded the evolution of philosophy and baffled his teachers. Spanning most of his life, from his early encounters with Bertrand Russell in Cambridge to a final trip to New York via the Russian Front, Wittgenstein: The Crooked Roads tracks the journeys of a tortured soul.
William Lyons, Professor Emeritus of Philosophy, Trinity College, Dublin, has written a moving and philosophically acute journey through successive decades of Wittgenstein's career. The play received its world premiere on 19 April 2011 at the Riverside Studios.
