C.S. Lewis

British novelist and Christian apologist — Oxford and Cambridge literature professor — author of The Chronicles of Narnia, The Screwtape Letters, Mere Christianity, and The Problem of Pain — the most widely read Christian apologist of the 20th century.

Creates Christian apologetics accessible to intellectuals — Lewis's argument that a materialist worldview cannot account for the very faculty (rational thought) required to evaluate it (his 'Argument from Reason') is the most philosophically sophisticated popular apologetic against naturalism.
