In lieu of an abstract, here is a brief excerpt of the content:Leibniz and Bayle: Manicheism and Dialectic DAVID NORTON LEIBNIZ' CLAIM that this is the "best of all possible worlds" has seemed so prima facie absurd that his critics have often considered the assertion adequately refuted by their pointing to things which are clearly "bad" and which might conceivably be "better." The paradigm case is Voltaire's Candide, which is certainly an effective refutation of Leibniz' claim at this level. We (...) can, however, by taking another point of view find what appear to be other absurdities in Leibniz' metaphysics. The point of view I wish to take, or attempt to take, is that of Pierre Bayle. I wish to suggest some objections to Leibniz which Bayle may have felt, but which he did not make explicit. Such an undertaking will, hopefully, add to our understanding of both Leibniz and Bayle. I What I propose to do is unorthodox, or at least unusual, and for that reason it is extremely important that the reader have from the very outset a clear idea of what is being undertaken. I can best clarify my aims, I think, by first attending briefly to some historical matters. Between 1695 and 1699 Bayle and Leibniz carried on a lively controversy over the latter's metaphysical views, though the debate was limited almost entirely to the notion of pre-established harmony. This controversy is well enough known that we need not stop over its details; in summary, Bayle first admits delight at what appears to be a new metaphysical explanation of the union of mind and body, but then goes on to argue that, after all, Leibniz' system is either no more than a reformulation of occasionalism, or impossible, since it violates clear and accepted metaphysical canons? Now, so far as we know, Bayle did not comment further on Leibniz' metaphysics, though the latter was * I wish to thank Prof. Harry M. Bracken, Arizona State University, and Prof. Richard H. Popkin, University of California, San Diego, for the suggestions and criticisms which they made of an earlier form of this paper. Their suggestions were all enlightening, if not all adopted-meaning, of course, that they would probably not agree with all that I here suggest. x Pierre Bayle, Dictionaire historique et critique, 5=. 6dition, revue, corrig6e, et augment6e, avec la vie de l'auteur, par Mr. Des Maizeaux, 4 tomes (Amsterdam, Leide.

Unfortunately, Bayle died before the Thdodicde was published and was deprived accordingly of any opportunity to reply to it. Bayle did, however, leave in the Dictionaire historique et critique a number of arguments against various metaphysical positions. The point of my paper is to show that certain of these arguments are applicable to Leibniz' system, and that applied to that system they reveal features of it which we might otherwise have overlooked. Bayle adduces arguments which seem with only slight modification to point directly at Leibniz--though without indicating that he has Leibniz in mind. I hope first of all to show what these arguments are and in what sense they refute Leibniz. I have said that Bayle gives no indication that these arguments of his apply to Leibniz; strictly speaking, this is correct. This does not mean, however, that I am understaking an unjustified wild goose chase through the Dictionaire : Bayle himself offers the motivation which has led to this study when he says in "Rorarius" (rem. L) that he has withheld some objections to Leibniz' opinions on the ground that these are no more objections to Leibniz than to certain other philosophers: "Je m'abstiens aussi de toutes les Objections qui ne sont pas plus contraires ~t son sentiment qu'~t celui de quelques autres Philosophes." In one sense then this paper can be thought of as my speculations of what these waived objections are... (shrink)
