C.S. Lewis on G.K. Chesterton via The Wardrobe Door, from Surprised By Joy:
His humour was of the kind I like best – not “jokes” imbedded in the page like currants in a cake, still less (what I cannot endure), a general tone of flippancy and jocularity, but the humour which is not in any way separable from the argument but is rather (as Aristotle would say) the “bloom” on dialectic itself. The sword glitters not because the swordsman set out to make it glitter but because he is fighting for his life and therefore moving it very quickly. For the critics who think Chesterton frivolous or “paradoxical” I have to work hard to feel even pity; sympathy is out of the question. Moreover, strange as it may seem, I liked him for his goodness.
“In reading Chesterton, as in reading [George] MacDonald, I did not know what I was letting myself in for. A young man who wishes to remain a sound atheist cannot be too careful of his reading. There are traps everywhere — “Bibles laid open, millions of surprises,” as Herbert says, “fine nets and stratagems.” God is, if I may say it, very unscrupulous.”
