If we extend our discourse to the boundless multitude of fishes – those in ponds, those in the springs, those in the rivers, those in the navigable sea, and those in the unnavigable –
or if we consider the untold numbers of flocks of birds – those in the air, those on land, those in the water as well as on the land (for there are a great number of aquatic birds among them), wild ones, tame ones, wild ones that have been domesticated,
those that always remain wild, edible ones, inedible ones – and if we investigate the beauty, the feathers, and the musical sound of each; if we but closely examine the differences in their singing, their food, their way of life, and if we recount their habits, their haunts, all the benefits and services they provide to us, their sizes, great and small,
their young and the rearing of them, and the great and inexpressible diversity among them, and if we also do the same with the fishes; and if from there we also go on to plants, which grow everywhere on the earth, and if for each of them we look at its fruit and its usefulness and its fragrance and its appearance,
its structure, its leaves, its color, its shape, its size, great or small, its benefits, its methods of cultivation, its kind of bark, trunk, branch, those growing in meadows and those in enclosed gardens; then if we go on to the various herbs and investigate the manifold places where they grow and the ways to find them,
to care for them, and to cultivate them, as well as their usefulness to us for healing; and if we also move on to the ore-bearing mountains, of which there are many; and if we search through all the other created things, which are even more numerous –
then, what words or what amount of time would be enough for us to come to a precise understanding of them?
And all that, O man, is for your sake: arts for your sake, and ways of living and cities and villages and sleep for your sake,
and death for your sake, and life for your sake, and growth, and so many works of nature and such a good world for your sake now – and for your sake it will be better still. Concerning the fact that it will be better and that it will be better for your sake,
listen to what the apostle Paul says: Because the creation itself also shall be delivered from the bondage of corruption, that is, from being corruptible. And how it will enjoy such an honor he shows by adding: into the liberty of the glory of the children of God (Rom. 8:21).
