u8One criticism of Leibniz's argument we cannot refrain from making. He allows himself too easy a triumph when he says that the only alternative to a choice determined by a prevailing inclination towards one proposal is a choice of mere caprice. There is a sort of choice Leibniz never so much as considers and which appears at least to fall quite outside his categories, and that is the sort of choice exercised in artistic creativity. In such choice we freely feel after the shaping of a scheme, we do not arbitrate simply between shaped and given possible schemes. And perhaps some such element enters into all our choices, since our life is to some extent [33] freely designed by ourselves. If so, our minds are even more akin to the divine mind than Leibniz realized. For the sort of choice we are now referring to seems to be an intuitive turning away from an infinite, or at least indefinite, range of less attractive possibility. And such is the nature of the divine creative choice. The consequence of such a line of speculation would be, that the divine mind designs more through us, and less simply for us, than Leibniz allowed: the 'harmony' into which we enter would be no longer simply 'pre-established'. Leibniz, in fact, could have nothing to do with such a suggestion, and he would have found it easy to be ironical about it if his contemporaries had proposed it.

Leibniz wrote two books; a considerable number of articles in learned periodicals; and an enormous number of unpublished notes, papers and letters, preserved in the archives of the Electors of Hanover not because of the philosophical significance of some of them, but because of the political importance of most of them. From among this great mass various excerpts of philosophical interest have been made by successive editors of Leibniz's works. It may be that the most profound understanding of his mind is to be derived from some of these pieces, but if we wish to consider the public history of Leibniz, we may set them aside.

Of the two books, one was published, and the other never was. The New Essays remained in Leibniz's desk, the Theodicy saw the light. And so, to his own and the succeeding generation, Leibniz was known as the author of the Theodicy.

The articles in journals form the immediate background to the two books. In 1696 Leibniz heard that a French translation of Locke's Essay concerning Human Understanding was being prepared at Amsterdam. He wrote some polite comments on Locke's great work, and published them. He also sent them to Locke, hoping that Locke would write a reply, and that Leibniz's reflexions and Locke's reply might be appended to the projected French translation. But Locke set Leibniz's comments aside. Leibniz, not to be defeated, set to work upon the New Essays, in which the whole substance of Locke's book is systematically discussed in dialogue. The New Essays were written in 1703. But meanwhile a painful dispute had broken out between Leibniz [34] and the disciples of Locke and Newton, in which the English, and perhaps Newton himself, were much to blame, and Leibniz thought it impolitic to publish his book. It was not issued until long after his death, in the middle of the century.

The discussion with Locke was a failure: Locke would not play, and the book in which the whole controversy was to be systematized never appeared. The discussion with Bayle, on the other hand, was a model of what a discussion should be. Bayle played up tirelessly, and was never embarrassingly profound; he provided just the sort of objections most useful for drawing forth illuminating expositions; he was as good as a fictitious character in a philosophical dialogue. And the book in which the controversy was systematized duly appeared with great eclat.

Here is the history of the controversy. In 1695 Leibniz was forty-nine years old. He had just emerged from a period of close employment under his prince's commands, and he thought fit to try his metaphysical principles upon the polite world and see what would come of it. He therefore published an article in the Journal des Savants under the title: 'New System of Nature and of the Communication of Substances, as well as of the Union between Soul and Body'. In the same year Foucher published an article in the Journal controverting Leibniz; and in the next year Leibniz replied with an 'Explanation'. A second explanation in the same year appeared in Basnage's Histoire des Ouvrages des Savants, in answer to reflexions by the editor. M. Pierre Bayle had all these articles before him when he inserted a note on Leibniz's doctrine in his article on 'Rorarius', in the first edition of his Historical and Critical Dictionary. The point of connexion between Rorarius and Leibniz was no more than this, that both held views about the souls of beasts.

Pierre Bayle was the son of a Calvinist pastor, early converted to Catholicism, but recovered to his old faith after a short time. He held academic employments in Switzerland and Holland; he promoted and edited the Nouvelles de la Republique des Lettres, and he produced that extraordinary work the Historical and Critical Dictionary. The notices it contains of authors and thinkers are little more than pegs upon which Bayle could hang his philosophical reflexions. He could write an intelligent discussion on any opinion; what he could not do was to reconcile the points of view from which he felt impelled to write upon this author and that.[35] His was not a systematic mind. So far as he had a philosophical opinion, he was a Cartesian; in theology he was an orthodox Calvinist. He could not reconcile his theology with his Cartesianism and he did not try to. He made a merit of the oppositions of faith to reason and reason to itself, so that he could throw himself upon a meritorious and voluntary faith.

There is nothing original in this position. It was characteristic of decadent scholasticism, it squared with Luther's exaggerations about the impotence of reason in fallen man, and Pascal had given his own highly personal twist to it. Bayle has been hailed as a forerunner of Voltairean scepticism. It would be truer to say that a Voltairean sceptic could read Bayle's discussions in his own sense and for his own purposes if he wished. But Bayle was not a sceptic. It is hard to say what he was; his whole position as between faith and reason is hopelessly confused. He was a scholar, a wit, and a philosophical sparring-partner of so perfectly convenient a kind that if we had not evidence of his historical reality, we might have suspected Leibniz of inventing him.

In the first edition of his Dictionary, under the article 'Rorarius', Bayle gave a very fair account of Leibniz's doctrine concerning the souls of animals, as it could be collected from his article in the Journal des Savants, 27 June 1695. He then proceeded to comment upon it in the following terms:

'There are some things in Mr. Leibniz's hypothesis that are liable to some difficulties, though they show the great extent of his genius. He will have it, for example, that the soul of a dog acts independently of outward bodies; that it stands upon its own bottom, by a perfect spontaneity with respect to itself, and yet with a perfect conformity to outward things.... That its internal perceptions arise from its original constitution, that is to say, the representative constitution (capable of expressing beings outside itself in relation to its organs) which was bestowed upon it from the time of its creation, and makes its individual character (Journal des Savants, 4 July 1695). From whence it results that it would feel hunger and thirst at such and such an hour, though there were not any one body in the universe, and though nothing should exist but God and that soul. He has explained (Histoire des Ouvrages des Savants, Feb. 1696) his thought by the example of two pendulums that should perfectly agree: that is, he supposes that according to the particular laws which put the soul upon action, it must feel hunger at such an hour; [36] and that according to the particular laws which direct the motion of matter, the body which is united to that soul must be modified at that same hour as it is modified when the soul is hungry. I will forbear preferring this system to that of occasional causes till the learned author has perfected it. I cannot apprehend the connexion of internal and spontaneous actions which would have this effect, that the soul of a dog would feel pain immediately after having felt joy, though it were alone in the universe. I understand why a dog passes immediately from pleasure to pain when, being very hungry and eating a piece of bread, he is suddenly struck with a cudgel. But I cannot apprehend that his soul should be so framed that at the very moment of his being beaten he should feel pain though he were not beaten, and though he should continue to eat bread without any trouble or hindrance. Nor do I see how the spontaneity of that soul should be consistent with the sense of pain, and in general with any unpleasing perceptions.
