II. From the Books on Nature.
1 In Opposition to Those of the School of Epicurus Who Deny the Existence of a Providence, and Refer the Constitution of the Universe to Atomic Bodies.
Is the universe one coherent whole, as it seems to be in our own judgment, as well as in that of the wisest of the Greek philosophers, such as Plato and Pythagoras, and the Stoics and Heraclitus? Or is it a duality, as some may possibly have conjectured? Or is it indeed something manifold and infinite, as has been the opinion of certain others who, with a variety of mad speculations and fanciful usages of terms, have sought to divide and resolve the essential matter of the universe, and lay down the position that it is infinite and unoriginated, and without the sway of Providence? For there are those who, giving the name of atoms to certain imperishable and most minute bodies which are supposed to be infinite in number, and positing also the existence of a certain vacant space of an unlimited vastness, allege that these atoms, as they are borne along casually in the void, and clash all fortuitously against each other in an unregulated whirl, and become commingled one with another in a multitude of forms, enter into combination with each other, and thus gradually form this world and all objects in it; yea, more, that they construct infinite worlds. This was the opinion of Epicurus and Democritus; only they differed in one point, in so far as the former supposed these atoms to be all most minute and consequently imperceptible, while Democritus held that there were also some among them of a very large size. But they both hold that such atoms do exist, and that they are so called on account of their indissoluble consistency. There are some, again, who give the name of atoms to certain bodies which are indivisible into parts, while they are themselves parts of the universe, out of which in their undivided state all things are made up, and into which they are dissolved again. And the allegation is, that Diodorus was the person who gave them their names as bodies indivisible into parts. But it is also said that Heraclides attached another name to them, and called them “weights;” and from him the physician Asclepiades also derived that name.
2. A Refutation of This Dogma on the Ground of Familiar Human Analogies.
How, shall we bear with these men who assert that all those wise, and consequently also noble, constructions (in the universe) are only the works of common chance? Those objects, I mean, of which each taken by itself as it is made, and the whole system collectively, were seen to be good by Him by whose command they came into existence. For, as it is said, “God saw everything that He had made, and, behold, it was very good.” But truly these men do not reflect on the analogies even of small familiar things which might come under their observation at any time, and from which they might learn that no object of any utility, and fitted to be serviceable, is made without design or by mere chance, but is wrought by skill of hand, and is contrived so as to meet its proper use. And when the object falls out of service and becomes useless, then it also begins to break up indeterminately, and to decompose and dissipate its materials in every casual and unregulated way, just as the wisdom by which it was skilfully constructed at first no longer controls and maintains it. For a cloak, for example, cannot be made without the weaver, as if the warp could be set aright and the woof could be entwined with it by their own spontaneous action; while, on the other hand, if it is once worn out, its tattered rags are flung aside. Again, when a house or a city is built, it does not take on its stones, as if some of them placed themselves spontaneously upon the foundations, and others lifted themselves up on the several layers, but the builder carefully disposes the skilfully prepared stones in their proper positions; while if the structure happens once to give way, the stones are separated and cast down and scattered about. And so, too, when a ship is built, the keel does not lay itself, neither does the mast erect itself in the centre, nor do all the other timbers take up their positions casually and by their own motion. Nor, again, do the so-called hundred beams in the wain fit themselves spontaneously to the vacant spaces they severally light on. But the carpenter in both cases puts the materials together in the right way and at the right time. And if the ship goes to sea and is wrecked, or if the wain drives along on land and is shattered, their timbers are broken up and cast abroad anywhere—those of the former by the waves, and those of the latter by the violence of the impetus. In like manner, then, we might with all propriety say also to these men, that those atoms of theirs, which remain idle and unmanipulated and useless, are introduced vainly. Let them, accordingly, seek for themselves to see into what is beyond the reach of sight, and conceive what is beyond the range of conception; unlike him who in these terms confesses to God that things like these had been shown him only by God Himself: “My eyes saw Your work, being till then imperfect.” But when they assert now that all those things of grace and beauty, which they declare to be textures finely wrought out of atoms, are fabricated spontaneously by these bodies without either wisdom or perception in them, who can endure to hear them talk in such terms of those unregulated atoms, than which even the spider, that plies its proper craft of itself, is gifted with more sagacity?
