In this book, renowned philosopher Anthony Kenny focuses on one of the central questions in the philosophy of religion: is the belief in God and faith in the divine word rational? Surveying what has been said on the topic by such major recent thinkers as Wittgenstein and Platinga, Kenny contructs his own account of what he calls "the intellectual virtue of reasonable belief which stands between skepticism and credulity," which he then applies to the Christian doctrine of faith. Kenny also addresses related questions such as the existence and nature of God and the problem of evil in a world created by an omnipotent being. A fascinating exploration of a subject presented in clear, accessible language, What is Faith? is essential reading for anyone who hopes to understand a debate that has now raged for two thousand years.
