“None of us think enough of these things on which the eye rests. But don't let us let the eye rest. Why should the eye be so lazy? Let us exercise the eye until it learns to see startling facts that run across the landscape as plain as a painted fence. Let us be ocular athletes. Let us learn to write essays on a stray cat or a coloured cloud. I have attempted some such thing in what follows; but anyone else may do it better, if anyone else will only try. ” (Gilbert Keith Chesterton)
