Abstract

By now widely read, Catherine Wilson’s book on Leibniz’s metaphysics needs no introduction to Leibniz scholars. This volume, like its companions in the ‘Studies in Intellectual History and the History of Philosophy’ series, succeeds in meeting high standards of historical and textual scholarship; of special note are Wilson’s remarkable grasp of the contribution that relatively minor figures made to Leibniz’s thought, and her familiarity with the European secondary literature. The book is, as a consequence, broader and historically richer than other books on Leibniz in English. Contributing to this historical flavor is also a more strategic feature of Wilson’s project—namely its exploration of Leibniz’s metaphysics “[not] as a collection of theses and principles, but developmentally and thematically”. The distinction seems to imply that while one could view Leibniz’s metaphysics as a collection of principles and theses, exactly “which principles and theses?” threatens to get wrongly answered: the “governing assumption” of a developmental approach is that “what the words of a [long-dead philosopher] mean cannot be determined by an internal inspection of the texts”. Or anyway, not precisely determined, with a high confidence of Leibniz’s intentions, and for some projects this may well matter. Surely it may well matter for someone inclined—as Wilson is not—to see the largest part of Leibniz’s metaphysics as a relatively unified system of theses and principles: the governing assumption, which beckons us to read Leibniz against the backdrop of his ancient, medieval, and modern heritage, is consistent with exploring the internal coherence of the theses and principles making up his metaphysical system. If much of the older secondary literature was mistaken in doing almost to the exclusion of, Wilson’s book can scarcely be charged with the same mistake. Were I asked to complain about Wilson’s approach, I would only suggest that her eagerness and ability to do has sometimes obscured the extent to which an internal inspection of the texts is needed in fairly doing.
