It is a thousand to one that the reader is looking at something that he has never seen: that is, never realised. He could not write an essay on such a post or wall: he does not know what the post or wall mean. He could not even write the synopsis of an essay; as “The Bed-Post; Its Significance–Security Essential to Idea of Sleep–Night Felt as Infinite–Need of Monumental Architecture,” and so on. He could not sketch in outline his theoretic attitude towards window-blinds, even in the form of a summary. “The Window-Blind–Its Analogy to the Curtain and Veil–Is Modesty Natural?–Worship of and Avoidance of the Sun, etc., etc.” 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.
