It's strange that Lewis was once feted as a talented apologist, especially with books such as 'Mere Christianity'. I remember reading this, and 'The abolition of Man' 30 years ago, and there is a kind of superficial polish to the rhetoric. But as others have said, Lewis had an unswerving addiction to the use of straw men, and especially false dichotomies, which pop up all over the place. In 'Man or rabbit' you get a corker - Christianity is the greatest truth ever told, or a fraud. Well, no, it could be a mistake, and it could be incoherent mush. And in 'Mere Christianity' he advances the famous or notorious trilemma. Was this man really a Professor at Cambridge?
