Then take all the secondary planets, all their motions, all the beings that vegetate, live, feel, think, act, on all these globes; you have only to increase the number of chances; multiply this number to all eternity—to what our weakness calls infinity—there will still be an unit in favor of the formation of the world, such as it is, by motion alone; therefore it is possible that, in all eternity, the motion of matter alone has produced the universe as it exists. Nay, this combination must, in eternity, of necessity happen. Thus, say they, not only it is possible that the world is as it is by motion alone, but it was impossible that it should not be so after infinite combinations.
Answer.
All this supposition seems to me to be prodigiously chimerical, for two reasons: the first is, that in this universe there are intelligent beings, and you cannot prove it possible for motion alone to produce understanding. The second is, that, by your own confession, the chances are infinity to unity, that an intelligent forming cause produced the universe. Standing alone against infinity, a unit makes but a poor figure.
Again Spinoza himself admits this intelligence; it is the basis of his system. You have not read him, but you must read him. Why would you go further than he, and, through a foolish pride, plunge into the abyss where Spinoza dared not to descend? Are you not aware of the extreme folly of saying that it is owing to a blind cause that the square of the revolution of one planet is always to the squares of the others as the cube of its distance is to the cubes of the distances of the others from the common centre? Either the planets are great geometricians, or the Eternal Geometrician has arranged the planets.
But where is the Eternal Geometrician? Is He in one place, or in all places, without occupying space? I know not. Has He arranged all things of His own substance? I know not. Is He immense, without quantity and without quality? I know not. All I know is, that we must adore Him and be just.
New Objection of a Modern Atheist.
Can it be said that the conformation of animals is according to their necessities? What are those necessities? Self-preservation and propagation. Now, is it astonishing that, of the infinite combinations produced by chance, those only have survived which had organs adapted for their nourishment and the continuation of their species? Must not all others necessarily have perished?
Answer.
This argument, taken from Lucretius, is sufficiently refuted by the sensation given to animals and the intelligence given to man. How, as has just been said in the preceding paragraph, should combinations produced by chance produce this sensation and this intelligence? Yes, doubtless, the members of animals are made for all their necessities with an incomprehensible art, and you have not the boldness to deny it. You do not mention it. You feel that you can say nothing in answer to this great argument which Nature brings against you. The disposition of the wing of a fly, or of the feelers of a snail, is sufficient to confound you.
