Spinoza presents the “dictates of reason” as the foundation of “the right way of living”. An influential reading of his position assimilates it to that of Hobbes. The dictates of reason are normative principles that prescribe necessary means to a necessary end: self-preservation. Against this reading I argue that, for Spinoza, the term “dictates of reason” does not refer to a set of prescriptive principles but simply the necessary consequences, or effects, of the mind's determination by adequate ideas. I draw on this conclusion in highlighting an abiding tension in Spinoza's notion of the preservation of one's being, which reinforces his divergence from Hobbes.

This is the most up-to-date and comprehensive interpretation of the philosophy of Gottfried Wilhelm Leibniz. Amongst its other virtues, it makes considerable use of unpublished manuscript sources. The book seeks to demonstrate the systematic unity of Leibniz's thought, in which theodicy, ethics, metaphysics and natural philosophy cohere. The key, underlying idea of the system is the conception of nature as an order designed by God to maximise the opportunities for the exercise of reason. From this idea emerges the view that this world is the best of all possible worlds, and an ethical ideal in which the well-being of human beings is promoted through the gradual extension of intellectual enlightenment.

This is a superbly crafted and exhaustively researched account of the development of Leibniz’s thought, his ambitious plans and undertakings, his myriad intellectual engagements, and his ceaseless comings and goings across Europe. It captures, accurately and in great detail, the remarkably expansive mind of a singularly creative thinker. It is an extraordinary achievement, for the task of writing an intellectual biography of Leibniz is huge. To read even a portion of what he wrote and read, in the languages in which he wrote and read it, to come to grips with the nuances of religion, politics, and intellectual practice that define his world, and to identify the hundreds of individuals, illustrious and forgotten, with whom he interacted would challenge even the most skilled and dedicated scholar. There is no doubt that Antognazza has met this challenge with a biography that surpasses any available account of Leibniz’s life.The book is divided into three parts. A brief introduction surveys past attempts at capturing the breadth of Leibniz’s thought and articulates “four basic, underlying theses” that unify the chapters to follow . They are: first, that Leibniz’s life and work need to be assessed as a whole as opposed to focusing narrowly on his contributions to one or another field; second, that Leibniz’s life and thought are integrated to a remarkable degree and that it is a mistake to

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Cambridge History of Seventeenth-Century Philosophy by Daniel Garber, Michael AyersDonald RutherfordDaniel Garber, Michael Ayers, editors. The Cambridge History of Seventeenth-Century Philosophy. 2 vols. Cambridge: Cambridge University Press, 1998. Pp. xii + 1616. Cloth, $175.Over a decade in preparation, this latest addition to the Cambridge History of Philosophy is an enormous achievement—both in its size and the contribution it makes to redefining [End Page 165] the landscape of seventeenth-century philosophy. The editors make no bones about their intention to rewrite the history of early modern philosophy, reversing the trend dominant through much of this century of reading seventeenth-century philosophers in the light of twentienth-century “interests and preconceptions” (4). As they note, the movement to historicize our understanding of seventeenth-century philosophy has been underway for some time in the English-speaking world, furthered in many cases by contributors to these volumes. From this perspective, the present work represents, if not the culmination, at least a progress report on these efforts and the success they have achieved.As in previous volumes of the Cambridge History, the subject matter is treated thematically. Consistent with their larger goal, the editors have further attempted to organize the volumes in a way that remains faithful to the expectations of the period. Part I sets the stage with chapters that establish the larger social and historical context: “The institutional setting” (Richard Tuck); “The intellectual setting” (Stephen Menn); and “European responses to non-European culture: China” (D.E. Mungello). For the rest, the editors write, “the structure of the collection corresponds to one way, at any rate, in which an educated European of the seventeenth century might have organized the domain of philosophy” (2). First comes logic (including method and general ontology); then, the primary categories of being (God, body, soul); finally, the basic operations of the soul (understanding, will, action), whose treatment comprehends the topics of epistemology and ethics.Part II, “Logic, Language, and Abstract Objects,” opens with three short chapters by Gabriel Nuchelmans that survey the terrain of seventeenth-century logic according to the traditional divisions of term, proposition/judgment, and argument. These are followed by contributions on “Method and the study of nature” (Peter Dear); “Universal, essences, and abstract entities” (Martha Bolton); and “Individuation” (Udo Thiel).The discussion of metaphysics proper begins in Part III with the most fundamental being: God. Included here are chapters that examine specific theological issues—“The idea of God” (Jean-Luc Marion); “Proofs of the existence of God” (Jean-Robert Armogathe); “The Cartesian dialectic of creation” (Thomas M. Lennon)—as well as ones that deal more broadly with the crucial connection between philosophy and religion: “The relation between theology and philosophy” (Nicholas Jolley) and “The religious background of seventeenth-century philosophy” (Richard Popkin).Part IV, “Body and the Physical World,” forms the single largest part of the book and its intellectual core. It opens with two chapters—“The scholastic background” (Roger Ariew and Alan Gabbey) and “The occultist tradition and its critics” (Brian Copenhaver)—that effectively mark out the boundaries of the “new philosophy” that emerges in conjunction with the development of seventeenth-century science. These are followed by a series of chapters that examine particular features of that philosophy: “Doctrines of explanation in late scholasticism and in the mechanical philosophy” (Steven Nadler); “New doctrines of body and its powers, place, and space” (Daniel Garber, John Henry, Lynn Joy, and Alan Gabbey); “Knowledge of the existence of body” (Charles McCracken); “New doctrines of motion” (Alan Gabbey); “Laws of nature” (J.R. Milton); and “The mathematical realm of nature” (Michael Mahoney). [End Page 166]The final section of Volume I takes up the third main category of being: “Spirit.” It begins with Daniel Garber’s overview of the positions of the major figures, “Soul and mind: Life and thought in the seventeenth century,” followed by chapters on “Knowledge of the soul” (Charles McCracken); “Mind-body problems” (Daniel Garber and Margaret Wilson); “Personal identity” (Udo Thiel); and “The passions in metaphysics and the theory of action” (Susan James).Volume II of the History is devoted to topics that, in one way or another, elaborate operations of the soul. Part V, “The...

Leibniz and the Rational Order of Nature is intended to offer a broad panorama on Leibniz’s philosophy. Although necessarily selective in its focus, it aspires to a comprehensive understanding of how the different parts of Leibniz’s philosophy — theodicy, ethics, metaphysics, natural philosophy — fit together in a coherent and compelling fashion. In the book, I indicate some of the places where tensions threaten the unity of this scheme. My primary goal, however, is to reconstruct a system that would be recognizable to Leibniz himself. Within this system, primacy is assigned to the doctrine of theodicy. Although many topics vied for Leibniz’s philosophical attention, none was more firmly embedded in his consciousness than the problem of comprehending the existence and nature of the world in a way consistent with its creation by a supremely wise and good God. One of the central theses of the book is that it is only against the background of this project that we can properly understand the details of Leibniz’s complex metaphysics.
