Chesterton lived and breathed on paradox. His ability to enlighten me on matters spiritual is nearly immeasurable, but there's the rub: he may only enlighten those things which one already knows, which already lurk in the mind and form the basis of his favorite virtue: common sense. No other author has such a talent for revealing to me the truths that are, or should be, immediately evident.
This is, in fact, the premise of one of his greatest books: Orthodoxy. In it, he voiced many of the questions that plagued him as a young seeker.
"How can we contrive to be at once astonished at the world and yet at home in it?"
"Why should ANYTHING go right; even observation and deduction? Why should not good logic be as misleading as bad logic? They are both movements in the brain of a bewildered ape?"
"Can [one] hate [the world] enough to change it, and yet love it enough to think it worth changing?"
