I argue that we can learn quite a lot about Leibniz’s metaphysics, in particular about monads and their relationship to time, by viewing Leibniz through a McTaggartian lens. After presenting McTaggart’s highly influential two basic conceptions of time, the A- (or tensed) and B- (or tenseless) conceptions, I distinguish four possible models of the relationship between monads and time: the fi rst two invoke tenses, differing in whether they treat non-present states as “real,” while the latter two are tenseless, differing in whether we construe the monad as (tenselessly) manifesting distinguishable perceptual states or as being in one indivisible but complex perceptual state representing the world as varying over time. A detailed study of the relative merits and demerits of the four models supports, I argue, the last model. Along the way I provide a Leibnizian account of the conscious illusion of temporal fl ow.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 39.3 (2001) 442-443 [Access article in PDF] Steven Nadler, editor. The Cambridge Companion to Malebranche. Cambridge Companions. New York: Cambridge University Press, 2000. Pp. xi + 319. Cloth, $54.95. With his own Cambridge Companion, the seventeenth-century French philosopher Nicolas Malebranche has at last arrived in the English speaking world. As editor Nadler puts it, "Malebranche was widely recognized by his philosophical and theological contemporaries... as an intellectual force to be reckoned with, a bold... synthesizer of... St. Augustine and Descartes and a systematic thinker of the first rank" (1). Yet until the relatively recent arrival of books or translations by scholars such as Nadler, McCracken, Jolley, Schmaltz, and Riley, Malebranche has largely been treated by Anglo-American scholars as merely the solitary proponent of the allegedly rather silly doctrine of occasionalism. The tide is now turning, and we may expect that over the next few years Malebranche's wide-ranging sophistication and significance will be more widely appreciated. Invaluable to that end will be Nadler's volume, which is of great interest both to those new to Malebranche and to seasoned scholars, for it presents accessible yet thorough introductions to Malebranche's many interesting doctrines—concerning self-knowledge, vision in God, continuous creation, occasionalism, theodicy, grace, freedom, morality, etc.—as well as raises important questions for future research. All of the essays Nadler has assembled are by well-known scholars, and all are worthwhile.The first point to make is that occasionalism—the view that God is the only true cause, and that finite substances lack all true causal power—was neither silly, nor was Malebranche its only proponent. As Nadler's own essay makes clear, the doctrine (or variations thereof) has roots in medieval philosophy as well as in Descartes, and was favored by other Cartesians preceding Malebranche, such as Cordemoy, la Forge, Geulincx, and Clauberg; further, Malebranche offered numerous distinct arguments for it, and, as evidenced in essays by Schmaltz, Rutherford, Kremer, and Riley, intended it to fit with his other metaphysical views in a complete and coherent system. Even if, as some of these same authors suggest, Malebranche failed to get everything to fit quite right, it's at least clear that the oft-raised charge that occasionalism was merely an ad hoc solution to the Cartesian mind-body problem is unjustified. There is of course room to disagree with certain details here: I've argued elsewhere, for example against Nadler, that despite evidence to the contrary Malebranche does not invoke continuous creation as an argument for occasionalism, and, in effect, against Kremer, that Malebranche can succeed in reconciling occasionalism and his conception of free will. But then the fact that scholars can disagree on points such as these is precisely evidence that Malebranche is a rich subject of study.Different essays have different virtues. Some are especially strong in philosophical analysis. Schmaltz provides penetrating analyses of Malebranche's doctrine that we see [End Page 442] all things "in God" as well as of related issues (such as the distinction between the intellectual and the sensible), and also traces their roots in or ramifications for thinkers such as Augustine, Descartes, Arnauld, and Regis; Kremer, too, does an impressive job disentangling the many discrete threads in Malebranche's theory of free will. Essays by Moreau and Riley are particularly useful for their overview or synthetic nature: Moreau presents the many points of contention in the decades-long dispute between Malebranche and Arnauld, while Riley makes explicit the implications that many of the doctrines discussed by other contributors have for Malebranche's moral theory (in the process perhaps implicitly supporting the claim that Malebranche's moral theory may be essential for understanding his metaphysics). Brown's and Robinet's contributions, the former detailing Malebranche's positive influence on or critical reception by figures such as Locke, Leibniz, Berkeley, Hume, and Reid, the latter focusing on disputes between Malebranche, Arnauld, and Leibniz, are essential for those interested (as all should be) in working Malebranche into standard undergraduate courses on modern philosophy, and will also be...
