After reading C.S. Lewis: A Life: Eccentric Genius, Reluctant Prophet by Alister E. McGrath I feel a bit like I actually know nothing at all about the works of C.S. Lewis. While I’ve not read the entire Lewis library, I have read the majority of his work, and for quite some time used Mere Christianity and The Screwtape Letters as teaching tools in various arenas. Mr. McGrath looks not so much of C.S. Lewis’s life as his writings that the criticism they received. Obviously, the life of C.S. Lewis permeates his writing on several levels, but what makes McGarth’s perspective so interesting is that not only do we get a better understanding of Lewis, but also an impression of his acceptance or rejection, often occurring at the same time, and the view point of his supporters and detractors. That being said, I often found myself not knowing enough about many of the competing ideas of Lewis’s day. I found myself sitting in physics class all over again. I was in awe of the concepts and laws that in my view brought the physical world and the divine in such close proximity, but when it came time to use that knowledge I just didn't have the chops needed in mathematics to turn my fascination into anything of substance. So I think I really enjoyed McGrath’s treatment of the 20th century’s greatest Christian apologist, but I’m not quite sure.
