Seriously, I would say that Chesterton is a harder read than Lewis - he's harder to follow initially, until you get his drift. When you do, look out!
In his biography (by Maisie Ward), relatives reported that doctors predicted that this kid with his huge head would be either a genius or an idiot.
An idiot doesn't get reprinted for a hundred years running.
I'd say that there are excellent answers at the website of the American Chesterton website
http://www.chesterton.org/ . People like Dale Alquist know more. But I’d be happy to do my best to answer any questions here (the OP is an old post that I missed).
