By Anthony Esolen, The Catholic Thing - Suppose you have homes falling to pieces everywhere in your town. You could look at the walls, that you concede are sometimes made of chalk. You could look at the roofing, because you sometimes notice a strange sag up above the eaves. But instead you fix upon the foundations. You notice that they are made of mere clay, and that groundwater riddles them with holes, so that some houses sink into the earth on this side or that, and sometimes people wake up in the morning to find that they have no house at all.
