Now, as one of the most gifted men of our time, whose eloquence was as great as his acumen and who gave great proofs of his vast erudition, had applied himself with a strange predilection to call attention to all the difficulties on this subject which I have just touched in general, I found a fine field for exercise in considering the question with him in detail. I acknowledge that M. Bayle (for it is easy to see that I speak of him) has on his side all the advantages except that of the root of the matter, but I hope that truth (which he acknowledges himself to be on our side) by its very plainness, and provided it be fittingly set forth, will prevail over all the ornaments of eloquence and erudition. My hope for success therein is all the greater because it is the cause of God I plead, and because one of the maxims here upheld states that God's help is never lacking for those that lack not good will. The author of this discourse believes that he has given proof of this good will in the attention he has brought to bear upon this subject. He has meditated upon it since his youth; he has conferred with some of the foremost men of the time; and he has schooled himself by the reading of good authors. And the success which God has given him (according to the opinion of sundry competent judges) in certain other profound meditations, of which some have much influence on this subject, gives him peradventure some right to claim the attention of readers who love truth and are fitted to search after it.
The author had, moreover, particular and weighty reasons inducing him to take pen in hand for discussion of this subject. Conversations which he had concerning the same with literary and court personages, in Germany and in France, and especially with one of the greatest and most accomplished of princesses, have repeatedly prompted him to this course. He had had the honour of expressing his opinions to this Princess upon divers passages of the admirable Dictionary of M. Bayle, wherein religion and reason appear as adversaries, and where M. Bayle wishes to silence reason after having made it speak too loud: which he calls the triumph of faith. The present author declared there and then that he was of a different opinion, but that he was nevertheless well pleased that a man of such great genius had brought about an occasion for going deeply into these subjects, subjects as important as they are difficult. He admitted having examined them also for some long time already, and having sometimes been minded to publish upon this matter some reflexions whose chief aim should be such knowledge of God as is needed to awaken piety and to foster virtue. This Princess exhorted and urged him to carry out his long-cherished intention, and some friends added their persuasions. He was all the more tempted to accede to their requests since he had reason to hope that in the sequel to his investigation M. Bayle's genius would greatly aid him to give the subject such illumination as it might receive with his support. But divers obstacles intervened, and the death of the incomparable Queen was not the least. It happened, however, that M. Bayle was attacked by excellent men who set themselves to examine the same subject; he answered them fully and always ingeniously. I followed their dispute, and was even on the point of being involved therein. This is how it came about.
I had published a new system, which seemed well adapted to explain the union of the soul and the body: it met with considerable applause even from those who were not in agreement with it, and certain competent persons testified that they had already been of my opinion, without having reached so distinct an explanation, before they saw what I had written on the matter. M. Bayle examined it in his Historical and Critical Dictionary, article 'Rorarius'. He thought that my expositions were worthy of further development; he drew attention to their usefulness in various connexions, and he laid stress upon what might still cause difficulty. I could not but reply in a suitable way to expressions so civil and to reflexions so instructive as his. In order to turn them to greater account, I published some elucidations in the Histoire des Ouvrages des Savants, July 1698. M. Bayle replied to them in the second edition of his Dictionary. I sent him a rejoinder which has not yet been published; I know not whether he ever made a further reply.
Meanwhile it happened that M. le Clerc had inserted in his Select Library an extract from the Intellectual System of the late Mr. Cudworth, and had explained therein certain 'plastic natures' which this admirable author applied to the formation of animals. M. Bayle believed (see the continuation of Divers Thoughts on the Comet, ch. 21, art. 11) that, these natures being without cognition, in establishing them one weakened the argument which proves, through the marvellous formation of things, that the universe must have an intelligent Cause. M. le Clerc replied (4th art. of the 5th vol. of his Select Library) that these natures required to be directed by divine wisdom. M. Bayle insisted (7th article of the Histoire des Ouvrages des Savants, August 1704) that direction alone was not sufficient for a cause devoid of cognition, unless one took the cause to be a mere instrument of God, in which case direction would be needless. My system was touched upon in passing; and that gave me an opportunity to send a short essay to the illustrious author of the Histoire des Ouvrages des Savants, which he inserted in the month of May 1705, art. 9. In this I endeavoured to make clear that in reality mechanism is sufficient to produce the organic bodies of animals, without any need of other plastic natures, provided there be added thereto the preformation already completely organic in the seeds of the bodies that come into existence, contained in those of the bodies whence they spring, right back to the primary seeds. This could only proceed from the Author of things, infinitely powerful and infinitely wise, who, creating all in the beginning in due order, had pre-established there all order and artifice that was to be. There is no chaos in the inward nature of things, and there is organism everywhere in a matter whose disposition proceeds from God. More and more of it would come to light if we pressed closer our examination of the anatomy of bodies; and we should continue to observe it even if we could go on to infinity, like Nature, and make subdivision as continuous in our knowledge as Nature has made it in fact.
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, 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.
This declaration of M. Bayle pledged me to an answer. I therefore purposed to point out to him, that unless it be said that God forms organic bodies himself by a perpetual miracle, or that he has entrusted this care to intelligences whose power and knowledge are almost divine, we must hold the opinion that God preformed things in such sort that new organisms are only a mechanical consequence of a preceding organic constitution.
