Speaking of the uniqueness of Man (compared to the other animals), Chesterton uses early cave paintings as a jumping off point for all sorts of things. Here, he ties the existence of art and creative energy back to maker with an interesting analogy.
…somehow or other a new thing had appeared in the cavernous night of nature; a mind that is like a mirror. It is like a mirror because it is truly a thing of reflection. It is a like a mirror because in it alone all the other shapes can be seen like shining shadows in a vision. Above all, it is like a mirror because it is the only thing of its kind. Other things may resemble it or resemble each other in various ways; other things may excel it or excel each other in various ways; just as in the furniture of a room a table may be round like a mirror or a cupboard may be larger than a mirror. But the mirror is the ol ting tht can contain them all. Man is a microcosm; man is the measure of all things; man is the image of God.
