What is mystical is not how the world is but that it is . . . ' (Ludwig Wittgenstein) The Spanish Carmelite reformer; Teresa of Avila and the Austrian professor of logic; Ludwig Wittgenstein do not at first sight seem to be the most obvious of bed fellows. Yet; in this strikingly original work; Dr Peter Tyler argues that both were galvinised through their reading to 'see the world aright' by a radical form of writing known as 'mystical'. As young adults both were in turmoil; loneliness and despair; yet found in this style of writing personal transformation; commitment and; most of all; engagement with the world. This new 'path to the heart'; argues the author; is what makes their writing so powerful and transformational to this day.
