A friend' Salvatore Sberna IV's comments on my thoughts on Chesterton's Orthodoxy:

Your article touches on several of my favorite passages from Chesterton.  The first section deftly discusses Chesterton's views on logic and its limitations and you pull the best quote from that particular chapter.
  You marry his ideas about logic with one of the more complex (in my opinion) ideas in Mere Christianity; the perversion of desire and the following of false gods in place of the true God.  Might I recommend a direct quote from Chesterton at this point to make to emphasize and explain the point as well as to break up the text (we who suffer from ADHD are  intimidated by large chunks of text)?  Perhaps a quote from "The Flag of the World:" "Because sexuality is sane, we can all go mad about sexuality.  Mere optimism had reached its insane and appropriate termination.  The theory that everything was good had become an orgy of everything that was bad."  Perhaps the paragraph before that sentence would work even better.
  Finally, you hit on the great romance of the book; that extremes (often attacked by critics) co-exist in Christianity and give the religion its dynamic force.  They aren't combined in some give and take admixture, but exist side by side in a wonderful, world changing tension.  This was my favorite part of your article.
  Along with the quote I mentioned, I would perhaps add that a way to understand Chesterton's apologetics versus Lewis' (and this is my thought at 12 AM Sunday morning, so take it with a grain of salt) is that Orthodoxy makes a case for Christianity by appealing to the English Romantic (fairy stories, the sensing of a divine plan, and seeing God through nature) while Mere Christianity appeals to the English Academic (i.e. giving my seat to a stranger on a train or sharing my orange).  Chesterton would have been welcome among the likes of Coleridge an and Wordsworth (an older Wordsworth) and his  and apologetics really fit in better with early 18th century English poets than mid-Century English Academics.  Well, that is my two-cents at least.
