also live and feel. So in the human mind the
vine providence that the art of God's ineffable healing turns even the foulness of sin into something that has a beauty of its own. xxix, 52. We have said enough for the pres- = ent about the benefit of authority. Let us see how far reason can advance from visible to invis ble things in its ascent from temporal to eternal things. We should not vainly behold the beauty of the sky, the order of the stars, the brightness of light, the alternations of day and night, the monthly courses of the moon, the fourfold seasons of the year, the meeting of the four elements, the life-force of seeds begetting forms and numbers, and all things that keep their nature and their appropriate measure each in its own kind. In considering these things there should be no exercise of vain and perishing curiosity, but a step should be taken towards immortal things that abide for ever. The first thing to notice is living nature which senses all these things. Because it gives life to the body it must necessarily excel the body. No mass of matter, however great or however bright, is to be held of much account if it is without life. Any living substance is by the law of nature to be preferred to any inanimate substance.
53. No one doubts that irrational animals also live and feel. So in the human mind the most excellent part is not that which perceives sensible objects but that which judges of sensible objects. Many animals see more sharply
Si. Augustine and have a keener sense of corporeal objects than men have. But to judge of bodies belongs not to life that is merely sentient, but to life that has also the power of reasoning. Where the animals are lacking, there is our excellence.
It is easy to see that that which judges is superior to that which is judged. For living reason judges not only of sensible things but also of the senses themselves. It knows why the oar dipped in water must appear crooked though it 1s really straight, and why the eyes must see it in that way. Ocular vision can only tell us that it is so but cannot judge. Wherefore it is manifest that as the life of sense excels the body the life of reason excels both. xxx, 54.
If rational life judges by itself alone, then there is nothing more excellent.
But clearly it is mutable, since it can be skilled at one moment and unskilled at another. The more skilled it is the better it judges, and its skill is in proportion to its participation in some art, discipline or wisdom. Now we must ask what is the nature of an art. By an art in this context I would have you understand not something that is observed by experience but something that is found out by reason. There is nothing very remarkable in knowing that sand and lime bind stones more securely together than mud, or that he who would build elegantly, must put a feature that is to be unique in the middle of the building, and, if there are several features, they must be made
