De Plantatione

If therefore any one wishes to escape from the difficulties of this question which present themselves in the different doubts thus raised, let him speak freely and say that there is nothing in any material of such power as to be able to support this weight of the world. But it is the eternal law of the everlasting God which is the most supporting and

This it is which, being extended from the centre to the borders, and again from the extremities to the centre, runs through the whole unsubdued course of nature, collecting all the parts and binding them firmly together; for the father who created them has made it the indissoluble bond of the universe.

Very naturally and appropriately therefore, all earth will not be dissolved by all water, which the bosom of the earth contains, nor will fire be extinguished by air, nor again will air be burnt up by fire, since the divine law establishes itself as a boundary to all these elements, like a vowel among consonants, so that the universe may, as it were, be harmonious in concert with the music expressed by letters; persuasion, by its own authority, putting an end to the threatening conflicts of contrary natures.

Thus then the plant which bears all things was rooted, and when it was rooted was made strong. But of the particular plants, and those of smaller growth, some were moveable, so as to have their places changed; and some were made so as, without any such change, to stand steadily in the same place.

Those then that are affected by motion, inducing change of place, which we call animals, are attached to the most important portions of the universe; the terrestrial animals to the earth, the animals which swim to the water, the winged animals to the air and those which can live in the flame to the fire (which last are said to be most evidently produced in Macedonia), and the stars are attached to the heaven. For those who have studied philosophy pronounce the stars also to be animals, being endowed with intellect and pervading the whole universe; some being planets, and moving by their own intrinsic nature; and others, that is the fixed stars, being borne along with the revolutions of the universe; so that they likewise appear to change their places.

But those which are regulated according to a nature devoid of all sensation, which are peculiarly called plants, have no participation in that motion which involves a change of place.

But the Creator made two different races on the earth and in the air. In the air, he made the winged animals capable of being perceived by the external senses, and other powers which can by no means be comprehended in any place
