In An Introduction to Wittgenstein's Philosophy of Religion, Brian R. Clack provides a much needed guide round the maze of Wittgenstein's thinking. The reader is introduced to Wittgenstein's philosophy and to his changing conception of religion, from the early view of the ineffability of the mystical to the later grammatical analysis of religious discourse. The work of neo-Wittgensteinian philosophers of religion is addressed, and the book ends with a controversial assessment of whether Wittgenstein's account of religion is compatible with faith.
