George Berkeley, Bishop of Cloyne, was one of the great philosophers of the early modern period. He was a brilliant critic of his predecessors, particularly Descartes, Malebranche, and Locke. He was a talented metaphysician famous for defending idealism, that is, the view that reality consists exclusively of minds and their ideas. Berkeley's system, while it strikes many as counter intuitive, is strong and flexible enough to counter most objections. His most studied works, the Treatise Concerning the Principles of Human Knowledge Principles, for short) and Three Dialogues between Hylas and Philonous Dialogues), are beautifully written and dense with the sort of arguments that delight contemporary philosophers. He was also a wide ranging thinker with interests in religion (which were fundamental to his philosophical motivations), the psychology of vision, mathematics, physics, morals, economics, and medicine. Although many of Berkeley's first readers greeted him with incomprehension, he influenced both Hume and Kant, and is much read (if little followed) in our own day.

That corpuscularianism played a critical role in Locke’s philosophical thought has perhaps now attained the status of a truism. In particular, it is universally acknowledged that the primary/secondary quality distinction and the conception of real essence found in the Essay Concerning Human Understanding cannot be understood apart from the corpuscularian science of Locke’s time.1 When Locke provides lists of the primary qualities of bodies,2 the qualities that “are really in them whether we perceive them or no,” those lists show strong resemblances to Robert Boyle’s views about the “primary affections” of matter, as expressed in such influential programmatic works as On the Origin of Forms and Qualities.3 Moreover, Locke’s conception of the real essences of bodies, the inner constitutions which serve as the causal sources of all their properties, typically appears to be a corpuscularian one.4 Nevertheless, the question of the nature of Locke’s philosophical allegiance to corpuscularianism remains a controversial one.5..

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Interpreting Arnauld ed. by Elmar J. KremerLisa DowningElmar J. Kremer, editor. Interpreting Arnauld. Toronto: University of Toronto Press, 1996. Pp. xi + 183. Cloth, $65.00.This attractive volume represents (with one exception) the proceedings of what was evidently a lively colloquium on Arnauld’s philosophy, held at the University of Toronto in 1994 to commemorate the three-hundredth anniversary of his death. Although Antoine Arnauld has been best known to contemporary philosophers as the author of the fourth set of objections to Descartes’ Meditations, interest in Arnauld’s own philosophical thought appears to be on the rise within the Anglo-American philosophical community, as indicated by the publication, within the last eight years, of two new translations of his Des vrayes et des fausses idées (a philosophical polemic against Malebranche) and a new translation of the Port-Royal Logic that Arnauld co-authored with Pierre Nicole. This new collection, from an international group of contributors, is thus well-timed. The two main themes that emerge from the collection as a whole serve to indicate the potential importance of Arnauld scholarship to our understanding of seventeenth century philosophy.The first theme that unites most of the papers is that of the diversity of views that existed within the constellation of philosophers who identified in one way or another with the doctrines of René Descartes. Arnauld was, of course, one such Cartesian. Nevertheless, many of the papers take the differences between Descartes and Arnauld as their starting point. Peter Schouls sets up a general contrast between the modernity of Descartes’ thought, as founded on the validity of subjective consciousness, and the tradition-grounded character of Arnauld’s philosophy. Jill Vance Buroker focuses productively on Arnauld’s and Descartes’ opposing views on the nature of assertion and judgment. Alan Nelson uses Arnauld’s challenge to Descartes’ account of the material falsity of ideas as the basis for a controversial but fascinating reassessment of a range of crucial issues in Descartes scholarship: clarity and distinctness, objective reality, and representation, as well as material falsity. Jean-Luc Solère’s contribution (described further below) documents the fact that significant philosophical debates existed, not [End Page 367] just within Cartesianism, but even within the still narrower Jansenist community that agreed in taking Augustine and Descartes as their philosophical models. In thus highlighting and documenting the diversity and richness of Cartesianism, the collection provides a valuable contribution to the history of philosophy. This theme is also very much present in the essays by Ndiaye, Kremer, and Carraud, which are discussed below.The second theme, shared by the majority of the papers, is that of philosophical theology. As Elmar Kremer remarks in his editor’s introduction (p. ix), while Arnauld himself held that philosophy and theology are distinguishable disciplines, the volume as a whole documents their many interconnections in his work. These interconnections are especially well brought out in the contributions by Kremer, Solère, and Sleigh. Kremer argues that we can understand three of Arnauld’s key departures from Descartes (with respect to the nature of body, the production of sensory ideas, and divine omnipotence) as motivated by his Christian commitments. Solère contends, in his intricate and illuminating essay, that Arnauld’s views about the metaphysical status of known truths (that they are relations in our minds, rather than entities in God grasped by us) are connected to a debate about the savability of non-Christians, and that his disputant, Pierre Nicole, developed an account of implicit or indirect knowledge in order to accommodate his commitment to general grace, a divine illumination had by everyone. Robert Sleigh’s essay considers the difficult question of how Arnauld wished to reconcile his doctrine of efficacious grace with human freedom: Arnauld clearly advocated some sort of compatibilism, but what sort, exactly? Although Sleigh admits that he cannot give an unambiguous defense of a single answer, his map of the territory is very valuable indeed. Other topics in philosophical theology touched on in the collection are the epistemology of papal infallibility (discussed by Thomas Lennon), miracles (discussed by Graeme Hunter) and divine omnipotence. This last topic (which is connected both to the question of the...

Locke’s metaphysical commitments are a matter of some controversy. Further controversy attends the issue of whether and how Locke adapts his views in order to accommodate the success of Newton’s Principia. The chapter lays out an interpretation of Locke’s commitments according to which Locke’s response to Newton on gravity does not require the positing of brute powers and is consistent with his core essentialism. The chapter raises the question of how the hypothesis concerning the creation of matter, alluded to at 4.10.18, fits with these commitments. The chapter concludes that the De grav hypothesis would represent a significant revision to the background metaphysical picture of the Essay, but that nevertheless its attractions to Locke are intelligible and illuminating.

One of the deepest tensions in Locke’s Essay, a work full of profound and productive conflicts, is one between Locke’s metaphysical tendencies—his inclination to presuppose or even to argue for substantive metaphysical positions—and his devout epistemic modesty, which seems to urge agnosticism about major metaphysical issues. Both tendencies are deeply rooted in the Essay. Locke is a theorist of substance, essence, quality. Yet, his favorite conclusions are epistemically pessimistic, even skeptical; when it comes to questions about how the world is constituted, our understandings cannot penetrate very far. Locke seems torn between metaphysics and modesty, between dogmatism and skepticism. This chapter will consider two specific examples of this sort of tension. The first involves the ontology of body, and the second, the ontology of mind. The conflict concerning bodily natures looks like this: As is well-known, Locke typically describes bodies in the terms of the corpuscularian science of his day, as exemplified especially by the natural philosopher Robert Boyle. Locke’s characterizations of the real essences of bodies are mechanist. He envisions them as corpuscularian textures-- spatial arrangements of particles possessing size.
