N.T. Wright considers Michael Ward’s Planet Narnia:
This introduction to a masterpiece is something of a masterpiece in its own right. Lewis’s ghost (whom Lewis envisaged as a possible benign presence around Magdalene College, Cambridge) has reason to be grateful that the crucial discovery was made by someone capable of expounding it with such subtlety and depth. There are tiny blemishes … but the overall effect is remarkable. Michael Ward has written a book whose “donegality” is the medieval scholarship, the poetic craftsmanship, the philosophical acumen and the imaginative genius of the self-consciously Jovial Lewis himself. It would be a great pity if the still prevailing Saturnine mood of our times, which has belittled and sometimes even reviled Lewis as a thinker, were to blind us to his remarkable literary, philosophical, cosmological and theological achievement.
