Lisa Downing focuses on the important issue of the metaphysics of Locke’s primary–secondary qualities distinction. In recent years this has returned as a topic of scholarly contention. Downing is concerned by the anti-realist trends in recent work on the metaphysics of Locke primary–secondary qualities distinction, and she is keen to defend the claims that Locke was ‘putting forward a kind of _realism_ about secondary qualities’ and that his realism does not readily appear to be a reductive form of realism. Downing begins with the traditional claim that Locke’s distinction was driven by his understanding of matter theory within the new science, like many others in the seventeenth century. From this perspective, she criticizes recent work on the nature and priority of primary qualities, which fail to root the primary in a metaphysical base or connect them to the metaphysical base in the wrong way. Next, she turns toward explaining her own understanding of the subordinate status of the secondary qualities, which brings Downing to Locke’s claim that secondary qualities are ‘mere powers’ and what this meant metaphysically to him.

Both Nicholas Malebranche and George Berkeley maintained that what was becoming a paradigmatic example of efficient causation—body-body causation at impact—is in fact not that at all, that God must be the efficient cause of such corporeal change. On some recent interpretations, they secure this conclusion by maintaining that only volitions, or beings with wills, are legitimate candidates to be efficient causes. This chapter argues against these interpretations. Malebranche does not rule out corporeal causes by fiat, but rather (and rightly) sees bodily impact as a serious challenge to his occasionalism, one which motivates him to emphasize his argument from continuous creation. And Berkeley does not rule in spiritual causes by fiat, nor by conflating efficient with final causation. The chapter also considers the extent to which their occasionalist conclusions overlap, and their divergence when it comes to drawing implications for physics from their metaphysical results.

It is long established that care is a feminist issue, even as feminists of different philosophical and political stripes disagree regarding the value of care as a guiding ethic. Into the debate on care comes ‘reactionary feminism’, a recent UK-based movement which argues that the technological advances of the sexual revolution have prioritized liberal freedom and alienated women from caring roles with deleterious effects. The most prominent ‘reactionary feminists’ are Louise Perry, author of The Case against the Sexual Revolution (2022), and Mary Harrington, author of Feminism against Progress (2023). This article reads Perry and Harrington with and against feminist writing that offers radical ways of thinking about care and freedom beyond domesticity and heteronormativity. These include the Laboria Cuboniks Collective's manifesto, Xenofeminism (2018), and my own concept of ethical ‘self-fulness’, propounded in my 2019 book, Selfish Women. Together, these constitute, respectively, collectivist and individualist ripostes to the reactionary feminists.

In this chapter, John Locke's anti‐Cartesian stances on the difference between body and space, on whether the soul always thinks, on the possibility of thinking matter, all connect back to the basic opposition to Cartesian overreaching in regard to essences. The chapter presents a summary of Locke's anti‐Cartesianism, which seems to fit with his own representation of his Cartesian inheritance, which, notoriously, is that it is minimal, consisting only in anti‐scholasticism. The only acknowledgment that Locke wishes to give Descartes is that reading his work helped him to shake off the influence of Aristotelianism. Descartes was not the only target of Locke's anti‐innatism, but he was surely a central one. Locke attacks the Cartesian doctrine of innate ideas because it poses a threat to his central empiricist commitments. Interestingly, he also sees the central tenets of Cartesian ontology as a threat.

Descartes and Boyle were the most influential proponents of strict mechanist accounts of the physical world, accounts which carried with them a distinction between primary and secondary (or sensible) qualities. For both, the distinction is a piece of natural philosophy. Nevertheless the distinction is quite differently articulated, and, especially, differently grounded in the two thinkers. For Descartes, reasoned reflection reveals to us that bodies must consist in mere extension and its modifications, and that sensible qualities as we conceive of them based on sense perception can pertain only to the mind. Just how we are supposed to arrive at this realization is, this essay will argue, a deep puzzle that brings us to the basic assumptions of Descartes' metaphysics. For Boyle, by contrast, while reflection can reveal the unique explanatory status of mechanism, and, thus, the primary/secondary quality distinction, only experience can confirm its truth. Our central focus will be on Descartes, and on the question: How does he intend to remove the sensible qualities from the physical world, how does he strip them from bodies? I will try to show that Descartes has an argument that he takes to show a priori that sensible qualities cannot be attributed to the material world (as foundational qualities, or, as we conceive of them based on sense experience). The argument fails, however, leaving him with at best a partly empirical case for removing the sensible qualities, based on the purported explanatory success of his physics.

This chapter focuses on Locke’s attempts to prove in the _Essay_ II. xiii. 11–14 that we have distinct ideas of body and of extension. The goal is both to evaluate this anti-Cartesian foray, and to use it to reflect on some intriguing and abstruse elements of Descartes’s ontology of body. The chapter shows that Locke’s engagement with Descartes goes surprisingly deep on this issue. It illustrates how many of Locke’s points on space, extension, and solidity are clarified by seeing them as responding to Descartes’s correspondence with More, in which Descartes specifically says that impenetrability results from extension.

The Cambridge Companion to Locke now joins the long list of titles available in this excellent series. As we have come to expect, the contributors to this Companion are distinguished and the result is comprehensive and eminently useful. This volume is one of the more accessible in the series, with most of the chapters pitched at a level accessible to advanced undergraduates and especially helpful to beginning graduate students. Many of the chapters will be of considerable interest to scholars; here I myself think especially of Edwin McCann’s chapter on Locke’s philosophy of body, which considerably advances our understanding of the place of mechanism in Locke’s thought. In addition, the notes, selective bibliography, and index of passages cited will serve as resources for readers at all levels of expertise.

The aim of this dissertation is to explore a central aspect of Berkeley's philosophy of science, namely, his philosophical account of the status of Newton's mechanics. In De Motu, Berkeley's treatise on mechanics, he makes plain that he accepts Newton's mechanics as an excellent scientific theory, while refusing to admit the existence of physical forces. Thus, Berkeley is an anti-realist about Newtonian mechanics. In the dissertation, I seek to identify the grounds and nature of this anti-realism. ;Although Berkeley's motivations for maintaining dynamical anti-realism are largely metaphysical, Berkeley's case against realism in De Motu does not presuppose an immaterialist metaphysics. Rather, his main argument in De Motu is based on a strict empiricism and a claim about the conceptual requirements for reference. Essentially, Berkeley maintains that we can't understand dynamics realistically because we lack any appropriate concepts of force, nor can we acquire any, given the sort of things that forces are supposed to be. Other ways in which Berkeley impugns dynamical realism in De Motu reveal interesting affinities between his position and Cartesianism. ;Berkeley's alternative to realism is, I argue, a sort of instrumentalism. Here I disagree with a number of commentators who have seen Berkeley as a reductionist, that is, someone who claims that dynamics is reducible to kinematics. I develop my interpretation of Berkeley's dynamical instrumentalism by showing how it is connected in important ways with his views about the aims of science and about the significant of action-guiding language. In conclusion, I contrast Berkeley's instrumentalism about forces with his realism about particles in Siris.

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...

Pierre Louis Moreau de Maupertuis’ famous and influential Discours sur les différentes figures des astres, which represented the first public defense of attractionism in the Cartesian stronghold of the Paris Academy, sometimes suggests a metaphysically agnostic defense of gravity as simply a regularity. However, Maupertuis’ considered account in the essay, I argue, is much more subtle. I analyze Maupertuis’ position, showing how it is generated by an extended consideration of the possibility of attraction as an inherent property and fuelled by an understanding of Lockean skepticism about knowledge of real essences that is more nuanced perhaps even than Locke’s own.

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.

I. Introduction Siris, Berkeley's last major work, is undeniably a rather odd book. It could hardly be otherwise, given Berkeley's aims in writing it, which are three-fold: 'to communicate to the public the salutary virtues of tar-water,'1 to provide scientific background supporting the efficacy of tar-water as a medicine, and to lead the mind of the reader, via gradual steps, toward contemplation of God.2 The latter two aims shape Berkeley's extensive use of contemporary natural science in Siris. In particular, Berkeley's focus on what he calls fire (or aether or light) as a quasiuniversal 'cause' of natural change3 serves these purposes, for the 'activity' of the aether, in his view, can both explain the miraculous virtues of a certain medicine, i.e. tar-water, and reveal God's action and his divine order.4 Berkeley's corpuscular speculations, including his use of fire-theory, are not especially idiosyncratic as natural philosophy. In his theorizing, as Jessop and other have noted, he is heavily indebted to the work of Hermann Boerhaave, the Dutch chemist, botanist, and physician whose teachings were highly influential in mid-eighteenth century Britain.5 Boerhaave, along with other Dutch natural philosophers cited by Berkeley, assigned a central role in accounting for physio-chemical activity to fire, a subtle, insensible particulate substance, sometimes identified with light.

Both Immanuel Kant and Paul Guyer have raised important concerns about the limitations of Lockean thought. Following Guyer, I will focus my attention on questions about the proper ambitions and likely achievements of inquiry into the natural/physical world. I will argue that there are at least two important respects, not discussed by Guyer, in which Locke’s account of natural philosophy is much more flexible and accommodating than may be immediately apparent. On my interpretation, however, one crucial source of a too-limited vision of natural philosophy remains in Locke, where he is appropriately criticized by both Kant and Guyer. My method will be to begin with a distinction that Locke draws in the very first draft of the Essay, between what he calls “the sensible object” and, on the other hand, “the uncertain philosophical cause.” I believe that Locke’s notion of “sensible object,” as opposed to uncertain philosophical cause, retains a central place in his thought in the published Essay, despite the fact thateven though this contrast is never made explicitly there. Tracing the evolution of these two concepts in his thought will allow us to track and better understand his developing views about the relation between the project of the.

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.
