So of the eye. All the telescopes and microscopes which man makes, curiously and cunningly as they are made, are clumsy things compared with the divine workmanship of the eye. I cannot describe it to you; nor, if I could, is this altogether a fit place to do so. But if any one wishes to see the greatness and the glory of God, and be overwhelmed with the sense of his own ignorance, and of God's wisdom, let him read any book which describes to him the eye of man, or even of beast, and then say with the psalmist, 'I am fearfully and wonderfully made. Marvellous are thy works, O Lord, and that my soul knoweth right well.' And remember, that as with the ear, so with the eye, the mere workmanship of it is only the beginning of the wonder. It is very wonderful that the eye should be able to take a picture of each thing in front of it; that on the tiny black curtain at the back of the eye, each thing outside should be printed, as it were, instantly, exact in shape and colour. But that is not sight. Sight is a greater wonder, over and above that. Seeing is this, that the picture which is printed on the back of the eye, is also printed on our brain, so that we _see_ it. There is the wonder of wonders. Do some of you not understand me? Then look at it thus. If you took out the eye of an animal, and held it up to anything, a man or a tree, a perfect picture of that man or that tree would be printed on the back of the dead eye: but the eye would not _see_ it. And why? Because it is cut off from the live brain of the animal to which it belonged; and therefore, though the picture is still in the eye, it sends no message about itself up to the brain, and is not seen. And how does the picture on the eye send its message about itself to the brain, so that the brain sees it? And how, again--for here is a third wonder, greater still--do _we_ ourselves see what our brain sees? That no man knows, and, perhaps, never will know in this world. For science, as it is called, that is, the understanding of this world, and what goes on therein, can only tell us as yet what happens, what God does: but of how God does it, it can tell us little or nothing; and of why God does it, nothing at all; and all we can say is, at every turn, "God is great."
