Wittgenstein: From Mysticism to Ordinary Language presents the Tractatus as a work of mystic theology intended to direct the reader to a transcendental plane from which human existence can be viewed from the divine perspective. More than any other work on Wittgenstein, this study integrates text material with personal biographical information, especially information dealing with his spiritual and psychological states. The result is a fresh, coherent, and extremely illuminating picture of Wittgenstein, successfully avoiding the pitfalls of either psychological reductionism or unfaithfulness to the text. It is bold without being reckless, passionately argued without being doctrinaire, and makes a very powerful and persuasive case for its main thesis.
