Samuel Newlands presents a sweeping new interpretation of Spinoza's metaphysical system and the way in which his metaphysics shapes, and is shaped by, his moral program. Engaging with contemporary metaphysics and ethics, Newlands reveals just how exciting and vibrant Spinoza's philosophical outlook remains for philosophers today.

Leibniz’s views on modality are among the most discussed by his interpreters. Although most of the discussion has focused on Leibniz’s analyses of modality, this essay explores Leibniz’s grounding of modality. Leibniz holds that possibilities and possibilia are grounded in the intellect of God. Although other early moderns agreed that modal truths are in some way dependent on God, there were sharp disagreements surrounding two distinct questions: (1) On what in God do modal truths and modal truth-makers depend? (2) What (...) is the manner(s) of dependence by which modal truths and modal truth-makers depend on God? Very roughly, Leibniz’s own answers are: (1) God’s intellect and (2) a form of ontological dependence. The essay first distinguishes Leibniz’s account from two nearby (and often misunderstood) alternatives found in Descartes and Spinoza. It then examines Leibniz’s theory in detail, showing how, on his account, God’s ideas provide both truth-makers for possibilities and necessities and an ontological foothold for those truth-makers, thereby explaining modal truths. Along the way, it suggests several refinements and possible amendments to Leibniz’s grounding thesis. It then defends Leibniz against a pair of recent objections by Robert Merrihew Adams and Andrew Chignell that invoke the early work of Kant. I conclude that whereas Leibniz’s alternative avoids collapsing into yet another form of Spinozism, the alternatives proposed by Adams, Chignell, and the early Kant do not. (shrink)

There was a consensus in late Scholasticism that evils are privations, the lacks of appropriate perfections. For something to be evil is for it to lack an excellence that, by its nature, it ought to have. This widely accepted ontology of evil was used, in part, to help explain the source of evil in a world created and sustained by a perfect being. during the second half of the seventeenth century, progressive early moderns began to criticize the traditional privative account (...) of evil on a variety of philosophical and theological grounds. Embedded in Scholastic Aristotelianism and applied to problems of evil, privation theory seemed to some like yet another instance of pre-modern pseudo-explanation.1Against this .. (shrink)

Spinoza studies have seen a renaissance of interest in his views on modality, from which considerable disagreement has emerged about Spinoza's modal commitments. Much of this disagreement stems from larger interpretive disagreements about Spinoza's metaphysics. After a brief introduction, this SEP article begins with Spinoza's views on the distribution of modal properties, which quickly leads the heart of Spinoza's metaphysics, intersecting his views on causation, inherence, God, ontological plenitude and the principle of sufficient reason. Although the question of whether Spinoza (...) was a necessitarian is the predominant topic of discussion in the recent secondary literature on Spinoza's modal views, Spinoza also sketches interesting accounts of the nature of modality and the ground of modality that shed fresh light on his modal commitments. Though understudied by recent interpreters, these latter topics were of interest to Spinoza's peers and remain vibrant research questions in contemporary metaphysics of modality. (shrink)

In this two-part series, I explore some of the most important and influential interpretations of Spinoza as an idealist. In this first part, I examine Hegel’s case for interpreting Spinoza as a kind of frustrated idealist and show how doing so raises fresh interpretative challenges for Spinoza’s contemporary readers.

According to a common reading, Spinoza and Leibniz stand on opposite ends of the modal spectrum. At one extreme lies ‘‘Spinoza the necessitarian,’’ for whom the actual world is the only possible world. At the other lies ‘‘Leibniz the anti-necessitarian,’’ for whom the actual world is but one possible world among an infinite array of other possible worlds; the actual world is privileged for existence only in virtue of a free decree of a benevolent God. In this paper, I challenge (...) both of these readings. Spinoza is no necessitarian and Leibniz is no anti-necessitarian – at least as these characterizations are usually understood. Rather, I contend, Spinoza and Leibniz are both anti-essentialists; they believe that the modality of objects can vary relative to how those objects are conceived. This shared commitment to anti-essentialism allows them to consistently affirm both necessitarianism and its denial, relative to different ways of conceiving the world. Their embrace of this modal theory, I further argue, is grounded in their similar views on metaphysical perfection, ontological plentitude, and the principle of sufficient reason. (shrink)

I argue that Spinoza endorses "conceptual dependence monism," the thesis that all forms of metaphysical dependence (such as causation, inherence, and existential dependence) are conceptual in kind. In the course of explaining the view, I further argue that it is actually presupposed in the proof for his more famed substance monism. Conceptual dependence monism also illuminates several of Spinoza’s most striking metaphysical views, including the intensionality of causal contexts, parallelism, metaphysical perfection, and explanatory rationalism. I also argue that this priority (...) of the conceptual does not commit Spinoza to forms of idealism or mentalism. The question of how to understand different kinds of metaphysical dependence is quite controversial in Spinoza studies; I address major alternative readings in the notes. But there I also try to draw connections to the growing debate in contemporary discussions about metaphysical dependence, as this topic is a happy point of shared interest between Spinoza and contemporary metaphysicians alike.

In this two-part series, I explore some of the most important and influential interpretations of Spinoza as an idealist. In this second part, I turn to more recent idealistic interpretations of Spinoza, including the important British idealist school (including Pollock, Martineau, Joachim, and John Caird) at the turn of the 20th century to a very recent and important kind of idealist reading found in the work of Michael Della Rocca.

According to Spinoza, what is the relationship between the mental – ideas, minds, and the attribute of Thought – and the conceptual – concepts, conceiving, and conceptual dependence? The natural and pervasive interpretive assumption that Spinoza’s appeals to the conceptual are synonymous with appeals to the mental ought to be rejected, a rejection that prevents some of his central metaphysical doctrines from otherwise collapsing into incoherence. A close reading of key texts shows instead that conceptual relations are attribute-neutral for Spinoza; (...) mental relations comprise a proper subset of conceptual relations. This surprising conclusion, that the conceptual outstrips the mental, also sheds new light the relationship between the attributes, the extent of parallelism, and the nature of extension. It also shows how Spinoza’s frequent privileging of the conceptual avoids collapsing into a kind of idealism, a central point on which the most novel recent interpretation of Spinoza (Michael Della Rocca’s) falters.

This is a book review of "Theism and Ultimate Explanation", by Timothy O'Connor.

In 1710 G. W. Leibniz published Theodicy: Essays on the Goodness of God, the Freedom of Man, and the Origin of Evil. This book, the only one he published in his lifetime, established his reputation more than anything else he wrote. The Theodicy brings together many different strands of Leibniz's own philosophical system, and we get a rare snapshot of how he intended these disparate aspects of his philosophy to come together into a single, overarching account of divine justice in (...) the face of the world's evils. At the same time, the Theodicy is a fascinating window into the context of philosophical theology in the seventeenth century. Leibniz had his finger on the intellectual pulse of his time, and this comes out very clearly in the Theodicy. He engages with all of the major lines of theological dispute of that time, demonstrating the encyclopaedic breadth of his understanding of the issues. Leibniz's Theodicy remains one of the most abiding systematic accounts of how evil is compatible with divine goodness. Any treatment of the problem of evil must, at some point, come to grips with Leibniz's proposed solution. This volume refreshes and deepens our understanding of this great work. Leading scholars present original essays which critically evaluate the Theodicy, providing a window on its historical context and giving close attention to the subtle and enduring philosophical arguments.

One vexing strand of Spinozism asserts that God's nature is more expansive than traditionally conceived and includes properties like being extended. In this paper, I argue that prominent early moderns embrace metaphysical principles about causation, mental representation, and modality that pressure their advocates towards such an expansive account of God's nature in similar ways. I further argue that the main early modern escape route, captured in notions like “eminent containment,” fails to adequately relieve the metaphysical pressures towards Spinozism. The upshot (...) is that those sympathetic with these early modern projects must embrace a costlier option if they are to successfully escape the orbit of Spinoza. (shrink)

This paper explores a PSR-connected trail leading from theistic idealism to a form of substance monism. In particular, I argue that the same style of argument available for a Leibnizian form of metaphysical idealism actually leads beyond idealism to something closer to Spinozistic monism. This path begins with a set of theological commitments about the nature and perfection of God that were widely shared among leading early modern philosophers. From these commitments, there arises an interesting case for metaphysical idealism, roughly (...) the thesis that only minds and mind-dependent states actually exist. However, I contend, that same theistic reasoning also leads to an idealist form of substance monism, the view that God is the only actual substance and that almost everything else is merely an intentional object in God’s mind.

Modality: A History provides readers a sweeping study of the history of philosophical work on modal concepts. Everyday discourse is saturated with appeals to what might be the case or to what must be true or to what cannot happen. Possibility, necessity, and impossibility are modal terms, and philosophers have long wondered how to best understand them. This volume traces the history of some of the most prominent and important contributions to our understanding of possibility and necessity over the past (...) two and half millennia of western philosophy, from ancient Greek philosophers through current debates in the 21st century. Over the course of nine chapters from prominent scholars, this volume traces a history of modal theorizing that begins with extended discussions of Aristotle and the Stoics. Several chapters discuss insights and disagreements among Latin, Arabic, and Jewish medieval scholastics, such as Al-Ghazâlî, Scotus, and Crescas. Three chapters center on early modern philosophers, whose modal views were deeply shaped by this conceptual inheritance but also departed from it in significant ways: Descartes, Malebranche, Locke, Spinoza, Leibniz, and Hume. Kant and Hegel's modal contributions are presented in their own chapter, and another chapter traces the legacy of Kant's account on early-to-mid 20th century modal views, including Husserl, Heidegger, Russell, and Quine. The revival of modal metaphysics in the more recent work of Kripke, Marcus, and Lewis has led to a new flourishing of modal theories, including in recent debates among neo-Aristotelians, as the final chapter illustrates. Although modal concepts are interesting and important on their own, theories of modality often intersect with other significant philosophical topics, such as time, freedom, and God. Modal concepts also extend beyond metaphysics. To illustrate the role of modality in other domains, several small-scale studies, or Reflections, are dispersed among these main chapters on modality in cosmology, religion, music, literature, and logic. Readers will learn how a seemingly timeless and changeless cluster of modal concepts have undergone significant revisions and enjoy a rich developmental history. (shrink)

Spinoza'sEthicspromises a path for sweeping personal transformations, but his accounts face two sets of overarching problems. The first concerns his peculiar metaphysics of action and agents; the second his apparent neglect of the very category of persons. Although these are somewhat distinct concerns, they have a common, unified solution in Spinoza's system that is philosophically rich and interesting, both in its own right and in relation to contemporary work in moral philosophy. After presenting the core of the problem facing Spinoza's (...) action theory, I turn to his overlooked account of selves, one that can be illuminated by contemporary work on so-called deep-self theories. I then show how Spinoza's distinctive account of selves prevents his action theory from collapsing into metaphysical incoherence, and conclude with an implication for Spinoza's broader account of transformation.

Throughout his philosophical career at Michigan, UCLA, Yale, and Oxford, Robert Merrihew Adams's wide-ranging contributions have deeply shaped the structure of debates in metaphysics, philosophy of religion, history of philosophy, and ethics. Metaphysics and the Good: Themes from the Philosophy of Robert Merrihew Adams provides, for the first time, a collection of original essays by leading philosophers dedicated to exploring many of the facets of Adams's thought, a philosophical outlook that combines Christian theism, neo-Platonism, moral realism, metaphysical idealism, and a (...) commitment to both historical sensitivity and rigorous analytic engagement. Tied together by their aim of exploring, expanding, and experimenting with Adams's views, these eleven essays are coupled with an intellectual autobiography by Adams himself that was commissioned especially for this volume. As the introduction to the volume explains, the purpose of Metaphysics and the Good is to explore Adams's work in the very manner that he prescribes for understanding the ideas of others. By experimenting with Adams's conclusions, "pulling a string here to see what moves over there, so to speak," as Adams puts it, our authors throw into greater relief what makes Adams such an original and stimulating philosopher. In doing so, these essays contribute not only to the exploration of Adams's continuing interests, but they also advance original and important philosophical insights of their own. (shrink)

Abstractabstract:I argue that Baumgarten's rich and once influential Metaphysica contains an ontology that pushes him toward a Spinozistic conclusion, one that he fiercely sought to avoid. After examining Baumgarten's distinctive account of the core of Spinozism, I present his path as a series of independently motivated steps, focusing on his general ontology and his accounts of the world and God. Baumgarten himself would not be happy with these results, and I concede that some of his efforts to thwart Spinozism look (...) promising. But there is one route to Spinozism that he fails to block, and at a key juncture, he inadvertently aids the Spinozist's cause. I conclude with an epilogue on how Baumgarten's path also foreshadows the next Spinozism flare-up heading into the German pantheism controversy. (shrink)
