Spinoza’s bold claim that there exists only a single infinite substance entails that finite things pose a deep challenge: How can Spinoza account for their finitude and their plurality? Taking finite bodies as a test case for finite modes in general I articulate the necessary conditions for the existence of finite things. The key to my argument is the recognition that Spinoza’s account of finite bodies reflects both Cartesian and Hobbesian influences. This recognition leads to the surprising realization there must (...) be more to finite bodies than their finitude, a claim that goes well beyond the basic substance-monism claim, namely, that anything that is, is in God. This leads to the conclusion, which may seem paradoxical, that finite bodies have both an infinite as well as a finite aspect to them. Finite bodies, I argue, both actively partially determine all the other finite bodies, thereby partially causing their existence insofar as they are finite, as well as are determined by the totality of other bodies. I articulate precisely what this infinite aspect is and how it is distinct from the general substance-monism dictum. (shrink)

This work examines the unique way in which Benedict de Spinoza combines two significant philosophical principles: that real existence requires causal power and that geometrical objects display exceptionally clearly how things have properties in virtue of their essences. Valtteri Viljanen argues that underlying Spinoza's psychology and ethics is a compelling metaphysical theory according to which each and every genuine thing is an entity of power endowed with an internal structure akin to that of geometrical objects. This allows Spinoza to offer (...) a theory of existence and of action - human and non-human alike - as dynamic striving that takes place with the same kind of necessity and intelligibility that pertain to geometry. This fresh and original study will interest a wide range of readers in Spinoza studies and early modern philosophy more generally. (shrink)

in his characteristically generous and searching discussion of my book, Spinoza, Daniel Garber rightly points out that I structure my interpretation of Spinoza’s system around the principle of sufficient reason. This is the principle that, as I and others sometimes put it, each fact has an explanation and is thus not brute, or the principle that each thing has an explanation. The ‘or’ will soon be important. Indeed, it might seem that I am too focused on the PSR—certainly I seem (...) that way to Garber1—for I seek to use the PSR to unlock any number of problems that interpreters of Spinoza have faced over the last three centuries. Garber does a great job of conveying the range of uses to which I put the PSR.. (shrink)

The article proposes a new solution to the long-standing problem of the universality of essences in Spinoza's ontology. It argues that, according to Spinoza, particular things in nature possess unique essences, but that these essences coexist with more general, mind-dependent species-essences, constructed by finite minds on the basis of similarities that obtain among the properties of formally-real particulars. This account provides the best fit both with the textual evidence and with Spinoza's other metaphysical and epistemological commitments. The article offers new (...) readings of how Spinoza understands not just the nature of essence, but also the nature of being, reason, striving, definitions, and different kinds of knowledge.

The article explores the idea that according to Spinoza finite thought and substantial thought represent reality in different ways. It challenges “acosmic” readings of Spinoza's metaphysics, put forth by readers like Hegel, according to which only an infinite, undifferentiated substance genuinely exists, and all representations of finite things are illusory. Such representations essentially involve negation with respect to a more general kind. The article shows that several common responses to the charge of acosmism fail. It then argues that we must (...) distinguish the well-founded ideality of representations of finite things from mere illusoriness, insofar as for Spinoza we can have true knowledge of what is known only abstractly. Finite things can be seen as well-founded beings of reason. The article also proposes that within Spinoza's framework it is possible to represent a finite thing without drawing on representations of mind-dependent entities. (shrink)

This paper proposes a reassessment of Hegel’s critical reading of Spinoza and of the charge of acosmism, for which this reading is known. We argue that this charge is actually the consequence of a more fundamental criticism, namely Spinoza’s presumable inability to conceive the unity of the finite and the infinite. According to Hegel, the infinite and the finite remain two poles apart in Spinoza’s metaphysics, which thus fails to be a true monism, insofar as it contains an irreducible duality. (...) Against this reading, we argue that Spinoza’s conception of the causal co-determination of finite modes entails the acknowledgment of their essentially infinite nature. The study of this particular instance of coincidentia oppositorum enables to counter some of Hegel’s criticisms as well as to illuminate a fairly unexplored aspect of Spinoza’s substance monism.

In this paper, I suggest an outline of a new interpretation of core issues in Spinoza’s metaphysics and philosophy of mind. I argue for three major theses. (1) In the first part of the paper I show that the celebrated Spinozistic doctrine commonly termed “the doctrine of parallelism” is in fact a confusion of two separate and independent doctrines of parallelism. Hence, I argue that our current understanding of Spinoza’s metaphysics and philosophy of mind is fundamentally flawed. (2) The clarification (...) and setting apart of the two doctrines will also put us in a position to present my second major thesis and address one of the more interesting and enduring problems in Spinoza’s metaphysics: how can the attribute of thought be, on the one hand, isomorphic with any other attribute, and yet, on the other hand, be isomorphic with God himself, who has infinitely many attributes? In the second part of the paper, I present Spinoza’s solution to this problem. I argue that the number and order of modes is the same in all attributes. Yet, modes of Thought, unlike modes of any other attribute, have an infinitely-faceted internal structure so that one and the same idea represents infinitely many modes by having infinitely many facets (or aspects). (3) This new understanding of the inner structure of ideas in Spinoza will lead us to my third thesis in which I explain and solve another old riddle in Spinoza’s metaphysics: his insistence on the impossibility of the human mind knowing any of God’s infinite attributes other than Thought and Extension. In the third part, I show some of the major ramifications of my new interpretation and respond to some important objections. In my conclusion I discuss the philosophical importance of my interpretation. I explain why Spinoza could not embrace reductive idealism in spite of the preeminence he grants to the attribute of Thought. I argue that Spinoza is a dualist -- not a mind-body dualist, as he is commonly conceived to be, but rather a dualist of Thought and Being. Finally, I suggest that Spinoza’s position on the mind-body issue breaks with the traditional categories and ways of addressing the subject by suggesting a view which grants clear primacy to Thought without accepting any idealist reduction of bodies to thought.

Central to Spinoza’s ethical theory is a model of human nature: the model of the free man. In this paper I argue that the idea of the free man is an inadequate idea when this is understood as the idea of a perfectly free finite thing. But when properly understood--that is, when the idea of the free man is understood as the idea of the perfection of our nature and power--the idea of the free man is a way of conceiving (...) God and is, as such, an adequate idea. (shrink)

In this paper I explore one issue in the history of German Idealism which has been widely neglected in the existing literature. I argue that Salomon Maimon was the first to suggest that Spinoza's pantheism was a radical religious (or 'acosmistic') view rather than atheism. Following a discussion of the historical context of Maimon's engagement with Spinoza, I point out the main Spinozistic element of Maimon 's philosophy: the view of God as the material cause of the world, or as (...) the subject in which all things inhere. I argue that this doctrine was the basis of Maimon's Law of Determinability. (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.

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.

While both intuitive knowledge and reason are adequate ways of knowing for Spinoza, they are not equal. Intuitive knowledge, which Spinoza describes as the ‘greatest virtue of mind’, is superior to reason. The nature of this superiority has been the subject of some controversy due to Spinoza's notoriously parsimonious treatment of the distinction between reason and intuitive knowledge in the Ethics. In this paper, I argue that intuitive knowledge differs from reason not only in terms of its method of cognition—but (...) also in terms of its content. More specifically, I maintain that there is something that is known by intuition, namely the unique essences of things, that is not known by reason. My argument is supported by an examination of Spinoza's account of essences in the Ethics, which reveals that he is committed to both unique and shared essences. Based on this dual commitment, I argue that whereas for Spinoza both reason and intuition can be said to reach adequate knowledge of the shared essence of a thing, the unique essence of a singular thing, which is nothing but its actual essence, can only be known through intuitive knowledge.

There are many aspects of the Ethics that seem to suggest, or perhaps even require the possibility of deducing finite modes from the infinite substance. Nonetheless, as many have noted even during Spinoza’s own time, it is far from clear that such a deduction can be successfully performed. In this chapter I argue that the expectation of a top-down deduction is unwarranted, and that interestingly enough, it is not only unwarranted with regard to Spinoza but with regard to Descartes as (...) well. I show this by pointing to the crucial role confusion plays for both, noting that our epistemic journey to clear and distinct or adequate knowledge begins with confusion, and that this trajectory is one of emending initially confused ideas. This shows that epistemically a bottom-up trajectory necessarily precedes a top-down one. My claim, however, goes beyond this point regarding the order of discovery. I argue that the state of confusion presupposes a plurality of finite modes, in Spinoza’s case, and substances and modes in Descartes’s. Confusion, I claim, amounts to an inadequate perception of an amalgam of ideas of a real plurality of things. Recognizing the metaphysical ground of confusion along with its central epistemic role brings to light the artificiality, and indeed ultimately the impossibility of a top-down deduction which is divorced from a preceding bottom-up analysis.

First published in 2002. Routledge is an imprint of Taylor & Francis, an informa company.

The second and final volume of the most authoritative English-language edition of Spinoza's writings The Collected Works of Spinoza provides, for the first time in English, a truly satisfactory edition of all of Spinoza's writings, with accurate and readable translations, based on the best critical editions of the original-language texts, done by a scholar who has published extensively on the philosopher's work. The centerpiece of this second volume is Spinoza’s Theological-Political Treatise, a landmark work in the history of biblical scholarship, (...) the first argument for democracy by a major philosopher, and a forceful defense of freedom of thought and expression. This work is accompanied by Spinoza’s later correspondence, much of which responds to criticism of the Theological-Political Treatise. The volume also includes his last work, the unfinished Political Treatise, which builds on the foundations of the Theological-Political Treatise to offer plans for the organization of nontyrannical monarchies and aristocracies. The elaborate editorial apparatus—including prefaces, notes, glossary, and indexes—assists the reader in understanding one of the world’s most fascinating, but also most difficult, philosophers. Of particular interest is the glossary-index, which provides extensive commentary on Spinoza’s technical vocabulary. A milestone of scholarship more than forty-five years in the making, The Collected Works of Spinoza is an essential edition for anyone with a serious interest in Spinoza or the history of philosophy.
