In order to explain this marvel of the formation of animals, I made use of a Pre-established Harmony, that is to say, of the same means I had used to explain another marvel, namely the correspondence of soul with body, [65] wherein I proved the uniformity and the fecundity of the principles I had employed. It seems that this reminded M. Bayle of my system of accounting for this correspondence, which he had examined formerly. He declared (in chapter 180 of his _Reply to the Questions of a Provincial_, vol. III, p. 1253) that he did not believe God could give to matter or to any other cause the faculty of becoming organic without communicating to it the idea and the knowledge of organic nature. Also he was not yet disposed to believe that God, with all his power over Nature and with all the foreknowledge which he has of the contingencies that may arrive, could have so disposed things that by the laws of mechanics alone a vessel (for instance) should go to its port of destination without being steered during its passage by some intelligent guide. I was surprised to see that limits were placed on the power of God, without the adduction of any proof and without indication that there was any contradiction to be feared on the side of the object or any imperfection on God's side. Whereas I had shown before in my Rejoinder that even men often produce through automata something like the movements that come from reason, and that even a finite mind (but one far above ours) could accomplish what M. Bayle thinks impossible to the Divinity. Moreover, as God orders all things at once beforehand, the accuracy of the path of this vessel would be no more strange than that of a fuse passing along a cord in fireworks, since the whole disposition of things preserves a perfect harmony between them by means of their influence one upon the other.
