Dr Peter Tyler is Director of the Pastoral Theology programme at St Mary's University College, Twickenham, London. His previous writings include John of the Cross: Outstanding Christian Thinker (Continuum 2010), Sources of Transformation - Revitilizing Christian Spirituality (Continuum 2010, edited with Dr Edward Howells) and The Way of Ecstasy - Praying with St Teresa of Avila (Canterbury-SCM 1997).

Tyler offers a penetrating reading of Wittgenstein. And if that is not enough, he harnesses this to examine both the development of the theologia mystica from Dionysius to the medieval period and specifically the writings of the great Spanish mystic Teresa of Avila. Even more importantly he returns to re-read Wittgenstein. Tyler's elegant and provocative book is a genuine contribution to philosophy, theology and the study of mysticism.
