Query: Dumbfounding gaps in logic

I am a believer who loves the Lewis of the Narnia books, but his more argumentative books, including this one, Mere Christianity, are often rather lacking in basic coherence. The gaps in logic are often dumbfounding.My favorite example is Lewis's argument that you cannot accept Jesus as a wise man unless you accept that he is God, because anyone who claims to be God, and isn't God, is barking mad. Putting aside the issue of whether "the hisorical Jesus" actually made such a claim, alas, anyone who has ever taken a even a cursory look at the great writers and sages throughout history knows that one minute they can be the fount of wisdom and the next can be absolutely off their rocker. Dostoevsky springs most immediately to mind.And thats not the worst gap in logic in the book.So, those looking for a reasoned defense of Christianity are strongly advised to go straight to G.K. Chesterton's The Everlasting Man and skip this one.
