G.K.Chesterton

But as St. Francis did not love humanity but men, so he did not love Christianity but Christ. Say, if you think so, that he was a lunatic loving an imaginary person; but an imaginary person, not an imaginary idea.

The end of the Dark Ages was not merely the end of a sleep. It was certainly not merely the end of a superstitious enslavement. It was the end of something belonging to a quite definite but quite different order of ideas.
