The best proof for design in the Universe I find in the different motions of the spheres, and in the fixed position of the stars in the spheres. For this reason you find all the prophets point to the spheres and stars when they want to prove that there must exist a Divine Being. Thus Abraham reflected on the stars, as is well known; Isaiah (xl. 26) exhorts to learn from them the existence of God, and says, “Lift up your eyes on high, and behold who hath created these things?” Jeremiah [calls God] “The Maker of the heavens”; Abraham calls Him “The God of the heavens” (Gen. xxiv. 7); [Moses], the chief of the Prophets, uses the phrase explained by us (Part I., chap, lxx.), “He who rideth on the heavens” (Deut. xxxiii. 26). The proof taken from the heavens is convincing; for the variety of things in the sublunary world, though their substance is one and the same, can be explained as the work of the influences of the spheres, or the result of the variety in the position of the substance in relation to the spheres, as has been shown by Aristotle. But who has determined the variety in the spheres and the stars, if not the Will of God? To say that the Intelligences have determined it is of no use whatever; for the Intelligences are not corporeal, and have no local relation to the spheres. Why then should the one sphere in its desire to approach the Intelligence, move eastward, and another westward? Is the one Intelligence in the east, the other in the west? or why does one move with great velocity, another slowly? This difference is not in accordance with their distances from each other, as is well known. We must then say that the nature and essence of each sphere necessitated its motion in a certain direction, and in a certain manner, as the consequence of its desire to approach its Intelligence. Aristotle clearly expresses this opinion. We thus have returned to the part from which we started; and we ask, Since the substance of all things is the same, what made the nature of one portion different from another? Why has this sphere a desire which produces a motion different from that which the desire of another sphere produces? This must have been done by an agent capable of determining. We have thus been brought to examine two questions:—(1) Is it necessary to assume that the variety of the things in the Universe is the result of Design, and not of fixed laws of Nature, or is it not necessary? (2) Assuming that all this is the result of Design, does it follow that it has been created after not having existed, or does Creatio ex nihilo not follow, and has the Being which has determined all this done always so? Some of those who believe in the Eternity of the Universe hold the last opinion. I will now begin the examination of these two questions, and explain them as much as necessary in the following chapters. CHAPTER XX
