Benedict de Spinoza is one of the most controversial and enigmatic thinkers in the history of philosophy. His greatest work, Ethics (1677), developed a comprehensive philosophical system and argued that God and Nature are identical. His scandalous Theological-Political Treatise (1670) provoked outrage during his lifetime due to its biblical criticism, anticlericalism, and defense of the freedom to philosophize. Together, these works earned Spinoza a reputation as a singularly radical thinker. -/- In this book, Steinberg and Viljanen offer a (...) concise and up-to-date account of Spinoza’s thought and its philosophical legacy. They explore the full range of Spinoza’s ideas, from politics and theology to ontology and epistemology. Drawing broadly on Spinoza’s impressive oeuvre, they have crafted a lucid introduction for readers unfamiliar with this important philosopher, as well as a nuanced and enlightening study for more experienced readers.

Yitzhak Melamed here offers a new and systematic interpretation of the core of Spinoza's metaphysics. In the first part of the book, he proposes a new reading of the metaphysics of substance in Spinoza: he argues that for Spinoza modes both inhere in and are predicated of God. Using extensive textual evidence, he shows that Spinoza considered modes to be God's propria. He goes on to clarify Spinoza's understanding of infinity, mereological relations, infinite modes, and (...) the flow of finite things from God's essence. In the second part of the book, Melamed relies on this interpretation of the substance-mode relation and the nature of infinite modes and puts forward two interrelated theses about the structure of the attribute of Thought and its overarching role in Spinoza's metaphysics. First, he shows that Spinoza had not one, but two independent doctrines of parallelism. Then, in his final main thesis, Melamed argues that, for Spinoza, ideas have a multifaceted structure that allows one and the same idea to represent the infinitely many modes which are parallel to it in the infinitely many attributes. Thought turns out to be coextensive with the whole of nature. Spinoza cannot embrace an idealist reduction of Extension to Thought because of his commitment to the conceptual separation of the attributes. Yet, within Spinoza's metaphysics, Thought clearly has primacy over the other attributes insofar as it is the only attribute which is as elaborate, as complex, and, in some senses, as powerful as God.

‘Substance’ (substantia, zelfstandigheid) is a key term of Spinoza’s philosophy. Like almost all of Spinoza’s philosophical vocabulary, Spinoza did not invent this term, which has a long history that can be traced back at least to Aristotle. Yet, Spinoza radicalized the traditional notion of substance and made a very powerful use of it by demonstrating – or at least attempting to demonstrate -- that there is only one, unique substance -- God (or Nature) -- and that (...) all other things are merely modes or states of God. Some of Spinoza’s readers understood these claims as committing him to the view that only God truly exists, and while this interpretation is not groundless, we will later see that this enticing and bold reading of Spinoza as an ‘acosmist’ comes at the expense of another audacious claim Spinoza advances, i.e., that God/Nature is absolutely and actually infinite. But before we reach this last conclusion, we have a long way to go. So, let me first provide an overview of our plan. In the first section of this paper we will examine Spinoza’s definitions of ‘substance’ and ‘God’ at the opening of his magnum opus, the Ethics. Following a preliminary clarification of these two terms and their relations to the other key terms defined at the beginning of the Ethics, we will briefly address the Aristotelian and Cartesian background of Spinoza’s discussion of substance. In the second section, we will study the properties of the fundamental binary relations pertaining to Spinoza’s substance: inherence, conception, and causation. The third section will be dedicated to a clarification of Spinoza’s claim that God, the unique substance, is absolutely infinite. This essential feature of Spinoza’s substance has been largely neglected in recent Anglo-American scholarship, a neglect which has brought about an unfortunate tendency to domesticate Spinoza’s metaphysics to more contemporary views. The fourth section will study the nature of Spinoza’s monism. It will discuss and criticize the interesting yet controversial views of the eminent Spinoza scholar, Martial Gueroult, about the plurality of substances in the beginning of the Ethics; address Spinoza’s claim in Letter 50 that, strictly speaking, it is improper to describe God as “one”; and, finally, evaluate Spinoza’s kind of monism against the distinction between existence and priority monism recently introduced into the contemporary philosophical literature. The fifth and final section will explain the nature, reality, and manner of existence of modes. We therefore have an ambitious plan; let’s get down to business. (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. (shrink)

In this essay, I suggest that Spinoza acknowledges a distinction between formal reality that is infinite and timelessly eternal and formal reality that is non-infinite (i. e., finite or indefinite) and non-eternal (i. e., enduring). I also argue that if, in Spinoza’s system, only intelligible causation is genuine causation, then infinite, timelessly eternal formal reality cannot cause non-infinite, non-eternal formal reality. A denial of eternal-durational causation generates a puzzle, however: if no enduring thing – not even the sempiternal, (...) indefinite individual composed of all finite, enduring things – is caused by the infinite, eternal substance, then how can Spinoza consistently hold that the one infinite, eternal substance is the cause of all things and that all things are modes of that substance? At the end of this essay, I sketch how Spinoza could deny eternal-durational causation while still holding that an infinite, eternal God is the cause of all things and that all things are modes. I develop the interpretation more in the companion essay. (shrink)

My two principal aims in this essay are interconnected. One aim is to provide a new interpretation of the ‘infinite modes’ in Spinoza’s Ethics. I argue that for Spinoza, God, conceived as the one infinite and eternal substance, is not to be understood as causing two kinds of modes, some infinite and eternal and the rest finite and non-eternal. That there cannot be such a bifurcation of divine effects is what I take the ‘infinite mode’ propositions, E1p21–23, to (...) establish; E1p21–23 show that each and every one of the immanent effects of an infinite and eternal God is an infinite and eternal mode. The other aim is to show that these propositions can be understood as part of an extended critical response to Descartes’s infamous doctrine that God creates eternal truths and true and immutable natures. If we have the correct (Spinozan) conceptions of what God is and how God works, we see that an eternal and infinite God can only be understood to cause ‘eternal truths,’ and that these eternal truths are infinite and eternal modes of God. (shrink)

Spinoza claims we can control any passion by forming a more clear and distinct idea of it. The interpretive consensus is that Spinoza is either wrong or over-stating his view. I argue that Spinoza’s view is plausible and insightful. After breaking down Spinoza’s characterization of the relevant act, I consider four existing interpretations and conclude that each is unsatisfactory. I then consider a further problem for Spinoza: how his definitions of ‘action’ and ‘passion’ make room (...) for passions becoming action. I propose two solutions to this problem, both of which yield a hint regarding what act Spinoza has in mind. Using that hint, I propose that we can appreciate Spinoza’s insight by considering how philosophizing about a feeling can 'kill the mood.' The act of grasping how a passion exemplifies certain general truths, I hold, is a distinctly rational activity that has all the features Spinoza describes. I conclude by showing how this interpretation fits with Spinoza’s larger views on rational knowledge, rational joy, the comprehensibility of passions, and the relation between second- and first-order ideas.

ABSTRACTMost of Spinoza’s arguments for God’s existence do not rely on any special feature of God, but instead on merely general features of substance. This raises the following worry: those arguments prove the existence of non-divine substances just as much as they prove God’s existence, and yet there is not enough room in Spinoza’s system for all these substances. I argue that Spinoza attempts to solve this problem by using a principle of plenitude to rule out the (...) existence of other substances and that the principle cannot be derived from the PSR, as many claim.Abbreviation: PSR: Principle of Sufficient Reason.

This article has two goals: a historical and a speculative one. The historical goal is to offer a coherent account of Spinoza’s view on mereological composition. The speculative goal is to show that Spinoza’s substance monism is distinct from versions of monism that are currently defended in metaphysics and that it deserves the attention of contemporary metaphysicians. Regarding the second goal, two versions of monism are currently defended and discussed in contemporary metaphysics: existence monism according to which there (...) actually exists exactly one concrete entity; and priority monism that is famously defended by Jonathan Schaffer and according to which there exists exactly one fundamental concrete being, the cosmos, and several derivative concrete beings that are the parts of the cosmos. In this article, I argue that substance monism is neither an existence nor a priority monism because, while Spinoza’s monist is committed to the existence of a unique fundamental individual—the substance—and to the existence of several derivative individuals—the bodies or modes of extension—, Spinoza denies that the substance is mereologically complex. Regarding the first goal, the paper solves several interpretative puzzles by arguing that Spinoza distinguishes between three kinds of composition and that his talk of composition between the substance and its modes is by his own light not to be interpreted as literally true.

The official definitions that appear at the beginning of four of the five parts of the "Ethics" do not include an account of "existence." However Spinoza does provide a definition of “existence” in the scholium to proposition 45 of Part 2. This is an odd place for such an important doctrine, and all the more so given that the account there differs from anything resembling commonsense. In this paper I show that, for Spinoza, to exist is to be (...) eternal. Existence in the strict sense is eternal existence. (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 (...) class='Hi'>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)

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)

: Perhaps the central problem which preoccupies Spinoza as a moral philosopher is the conflict between reason and passion. He belongs to a long tradition that sees the key to happiness and virtue as mastery and control by reason over the passions. This mastery, however, is hard won, as the passions often overwhelm its power and subvert its rule. When reason succumbs to passion, we act against our better judgment. Such action is often termed 'akratic'. Many commentators have complained (...) that the psychological principles that Spinoza appeals to in his account of akrasia are mere ad hoc modifications to his philosophical psychology. I show, on the contrary, that these principles follow from some of the most important and interesting aspects of Spinoza's philosophy of mind. (shrink)

The very first line of Spinoza’s magnum opus, the Ethics, states the following surprising definition: By cause of itself I understand that whose essence involves existence, or that whose nature cannot be conceived except as existing [Per causam sui intelligo id, cujus essentia involvit existentiam, sive id, cujus natura non potest concipi, nisi existens]. As we shall shortly see, for many of Spinoza’s contemporaries and predecessors the very notion of causa sui was utterly absurd, akin to a Baron (...) Munchausen attempting to lift himself above a river by pulling his hair up. How can a thing cause itself into existence, if before the causal activity, the cause did not exist at all? Indeed, in one of his earliest works, Spinoza himself claimed: “No thing, considered in itself, has in itself a cause enabling it to destroy itself (if it exists), or to make itself [te konnen maaken] (if it does not exist)” (KV II 26|I/110/14-16). Moreover, in other early works, Spinoza refers to God as an “uncreated thing” (TIE §97) or “uncreated substance” (CM II 1|I/237/20), and not as a cause-of-itself as in the Ethics. What made Spinoza desert the common, traditional, view of God as the uncaused first cause, or uncreated substance, and adopt instead the apparently chimerical notion of God as causa sui? A very likely explanation for this development suggests that Spinoza’s rationalism, his commitment to the principle that everything must have a reason both for its existence and for its non-existence – a commitment stated clearly both in the Ethics (see, for example, E1p8s2 and E1p11d2), and in Spinoza’s other writings (see, for example, Ep. 34 (IV/179/29)) – made him realize that the notion of an uncreated, or uncaused, thing is of no use for him: if everything must have a cause, then the first cause, or the most fundamental being, must be a cause-of-itself. All this is well and good, but we should not let Spinoza off the hook so easily, for the immediate question which arises now is whether Spinoza is not simply cheating his readers. Does Spinoza have a reason – i.e., argument – that could convince us that causa sui is indeed a more adequate characterization of God and not merely an opportunistic and ad hoc façade for the good old uncaused cause? While there are many important questions surrounding Spinoza’s notion of causa sui, it is the last question which will be the focus of this short chapter. In the first part of this chapter, we study, briefly, Descartes’ engagement with the notion of causa sui. In the second part, I show that Spinoza understood the causation of causa sui as efficient, and not formal, causation. The third and final part will attempt to locate precisely the alleged problem with the notion of causa sui, and consider how could Spinoza defend the intelligibility of this notion. Regrettably, limitations of space will force us to leave the examination of Spinoza’s closely related notion of being-conceived. (shrink)

An old question in Spinoza scholarship is how finite, non-eternal things transitively caused by other finite, non-eternal things (i. e., the entities described in propositions like E1p28) are caused by the infinite, eternal substance, given that what follows either directly or indirectly from the divine nature is infinite and eternal (E1p21–23). In “Spinoza’s Monism I,” I pointed out that most commentators answer this question by invoking entities that are indefinite and sempiternal, but argued that perhaps we should not (...) be so quick to assume that in Spinoza’s system, an infinite and eternal substance could cause such indefinite, sempiternal entities. But if such eternal-durational causation is denied, then it seems harder to see how Spinoza’s system could be coherent: if Spinoza holds that the infinite, eternal substance cannot cause anything that is not infinite and not eternal, then how can he also hold that all things are modes immanently caused by substance (E1p15, E1p18, E1p25)? In this essay, I explain how Spinoza’s system could be understood in light of a denial of eternal-durational causation. On the interpretation I offer, God is the cause of all things and all things are modes because the essences of all things follow from the divine nature and all essences enjoy infinite, eternal reality as modes immanently caused by the infinite, eternal substance. The same non-substantial essences can also be conceived as enjoying non-infinite, non-eternal reality, but so conceived, they are enduring, finite (or sempiternal, indefinite) entities that cannot be conceived as modes caused by and inhering in the one infinite, eternal substance. I conclude by pointing out that if we take this interpretive route, we do have to understand Spinoza as committed to acosmism, or a denial of the reality of the world – at least the world of enduring, finite things.

: Two common ways of explaining akrasia will be presented, one which focuses on strength of desire and the other which focuses on action issuing from practical judgment. Though each is intuitive in a certain way, they both fail as explanations of the most interesting cases of akrasia. Spinoza 's own thoughts on bondage and the affects follow, from which a Spinozist explanation of akrasia is constructed. This account is based in Spinoza 's mechanistic psychology of cognitive affects. (...) Because Spinoza 's account explains action asissuing from modes of mind that are both cognitive and affective, it captures the intuitions that motivate the two traditional views while avoiding the pitfalls that result from their one‐sided approaches. This project will allow us a fuller understanding of Spinozist moral psychology. In addition to this historical value, the Spinozist theory may offer a satisfactory explanation of certain hard cases of akrasia while avoiding the problems be set by other theories. For this reason, the Spinozist account could also be seen as a useful contribution to our philosophical understanding of the phenomenon of akrasia. (shrink)

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. (shrink)

In this paper, I argue that Spinoza holds a perspectivalist view of mereological composition, a form of anti-realism. The paper has two parts: In the first half of the paper, I introduce interpretive puzzles for the standard realist reading of Spinoza’s mereology. In the second half of the paper, I discuss Spinoza’s positive view on mereological composition and present a perspectivalist reading that avoids the interpretive puzzles.

This chapter argues that the standard conception of Spinoza as a fellow-travelling mechanical philosopher and proto-scientific naturalist is misleading. It argues, first, that Spinoza’s account of the proper method for the study of nature presented in the Theological-Political Treatise (TTP) points away from the one commonly associated with the mechanical philosophy. Moreover, throughout his works Spinoza’s views on the very possibility of knowledge of nature are decidedly sceptical (as specified below). Third, in the seventeenth-century debates over proper (...) methods in the sciences, Spinoza sided with those that criticized the aspirations of those (the physico-mathematicians, Galileo, Huygens, Wallis, Wren, etc) who thought the application of mathematics to nature was the way to make progress. In particular, he offers grounds for doubting their confidence in the significance of measurement as well as their piece-meal methodology (see section 2). Along the way, this chapter offers a new interpretation of common notions in the context of treating Spinoza’s account of motion (see section 3). (shrink)

“Why did God create the World?” is one of the traditional questions of theology. In the twentieth century this question was rephrased in a secularized manner as “Why is there something rather than nothing?” While creation - at least in its traditional, temporal, sense - has little place in Spinoza’s system, a variant of the same questions puts Spinoza’s system under significant pressure. According to Spinoza, God, or the substance, has infinitely many modes. This infinity of modes (...) follow from the essence of God. If we ask: “Why must God have modes?,” we seem to be trapped in a real catch. On the one hand, Spinoza’s commitment to thoroughgoing rationalism demands that there must be a reason for the existence of the radical plurality of modes. On the other hand, the asymmetric dependence of modes on the substance seems to imply that the substance does not need the modes, and that it can exist without the modes. But if the substance does not need the modes, then why are there modes at all? Furthermore, Spinoza cannot explain the existence of modes as an arbitrary act of grace on God’s side since Spinoza’s God does not act arbitrarily. Surprisingly, this problem has hardly been addressed in the existing literature on Spinoza’s metaphysics, and it is my primary aim here to draw attention to this problem. In the first part of the paper I will present and explain the problem of justifying the existence of infinite plurality modes in Spinoza’s system. In the second part of the paper I consider the radical solution to the problem according to which modes do not really exist, and show that this solution must be rejected upon consideration. In the third and final part of the paper I will suggest my own solution according to which the essence of God is active and it is this feature of God’s essence which requires the flow of modes from God’s essence. I also suggest that Spinoza considered radical infinity and radical unity to be roughly the same, and that the absolute infinity of what follow from God’s essence is grounded in the absolute infinity of God’s essence itself.

The paper offers a new account of Spinoza's conception of “substance”, the fundamental building block of reality. It shows that it can be demonstrated apriori within Spinoza's metaphysical framework that (i) contrary to Idealist readings, for Spinoza there can be no substance that is not determined or modified by some other entity produced by substance; and that (ii) there can be no substance (and hence no being) that is not a thinking substance.

Spinoza's causal axiom is at the foundation of the Ethics. I motivate, develop and defend a new interpretation that I call the ‘causally restricted interpretation’. This interpretation solves several longstanding puzzles and helps us better understand Spinoza's arguments for some of his most famous doctrines, including his parallelism doctrine and his theory of sense perception. It also undermines a widespread view about the relationship between the three fundamental, undefined notions in Spinoza's metaphysics: causation, conception and inherence.

It is common to assimilate Marx’s and Spinoza’s conceptions of democracy. In this chapter, I assess the relation between Marx’s early idea of “true democracy” and Spinozist democracy, both the historical influence and the theoretical affinity. Drawing on Marx’s student notebooks on Spinoza’s Theological-Political Treatise, I show there was a historical influence. However, at the theoretical level, I argue that a sharp distinction must be drawn. Philosophically, Spinoza’s commitment to understanding politics through real concrete powers does not (...) support with Marx’s anti-institutional conception of true democracy. And as a matter of social theory, the gap between civil society and the state which so troubles Marx is a development of modernity that has not entered Spinoza's premodern field of view. Marx’s true democracy was also influenced by his study of Rousseau, and theoretically, it is just as close if not closer to Rousseau as to Spinoza. (shrink)

What I plan to do in this paper is to provide a survey of the ways in which Spinoza’s philosophy has been deployed in relation to early modern thought, in the history of ideas and in a number of different domains of contemporary philosophy, and to offer an account of how some of this research has developed. The past decade of research in Spinoza studies has been characterized by a number of tendencies; however, it is possible to identify (...) four main domains that characterize these different lines of research: studies of Spinoza’s individual works, of its problematic concepts, from the point of view of the history of ideas, and comparative studies of Spinoza’s ideas.

This book offers a detailed study of the political philosophies of Thomas Hobbes and Benedict de Spinoza, focussing on their concept of power as potentia, concrete power, rather than power as potestas, authorised power. The focus on power as potentia generates a new conception of popular power. Radical democrats–whether drawing on Hobbes's 'sleeping sovereign' or on Spinoza's 'multitude'–understand popular power as something that transcends ordinary institutional politics, as for instance popular plebsites or mass movements. However, the book argues (...) that these understandings reflect a residual scholasticism which Hobbes and Spinoza ultimately repudiate. Instead, on the book's revisionist conception, a political phenomenon should be said to express popular power when it is both popular (it eliminates oligarchy and encompasses the whole polity), and also powerful (it robustly determines political and social outcomes). Two possible institutional forms that this popular power might take are distinguished: Hobbesian repressive egalitarianism, or Spinozist civic strengthening. But despite divergent institutional proposals, the book argues that both Hobbes and Spinoza share the conviction that there is nothing spontaneously egalitarian or good about human collective existence. From this point of view, the book accuses radical democrats of pernicious romanticism; the slow, meticulous work of organizational design and maintenance is the true centre of popular power.

Spinoza is most often seen as a stern advocate of mechanistic efficient causation, but examining his philosophy in relation to the Aristotelian tradition reveals this view to be misleading: some key passages of the Ethics resemble so much what Surez writes about emanation that it is most natural to situate Spinoza's theory of causation not in the context of the mechanical sciences but in that of a late scholastic doctrine of the emanative causality of the formal cause; as (...) taking a look at the seventeenth-century philosophy of mathematics reveals, this is in consonance also with Spinoza's geometrical cast of mind. Against this background, I examine Spinoza's essentialist model of causation according to which each thing has a formal character determined by the thing's essence and what follows from that essence. In the case of real things this essential causal architecture results in efficacy, i.e. in bringing about real effects, the key idea being that without the essential, formally structured causal thrust there would be no efficacy in the first place. I also explain how this model accounts for efficient causation taking place between finite things. (shrink)

In this paper, I inspect the grounds for the mature Spinozist argument for substance monism. The argument is succinctly stated at Ethics Part 1, Proposition 14. The argument appeals to two explicit premises: (1) that there must be a substance with all attributes; (2) that substances cannot share their attributes. In conjunction with a third implicit premise, that a substance cannot not have any attribute whatsoever, Spinoza infers that there can be no more than one substance. I begin the (...) inspection with the analysis of the first premise, which is provided in the form of the four proofs of God’s existence in Ethics Part 1, Proposition 11. While demonstrating how Spinoza adopts a progressive approach, where the fourth proof of God’s existence is more successful and persuasive than the third, which is more successful than the second, etc., I also unpack concepts central to Spinoza’s thinking here, including the concepts of reason (ratio) and power (potesta or potentia). I then analyze the second premise of the Spinozist argument for substance monism, as established by Ethics Part 1, Proposition 4 in conjunction with Ethics Part 1, Proposition 5. I take up and respond to the objection attributed to Leibniz that a substance p can have the attributes x and y and a substance q can have the attributes y and z, and thus that substances can share some attributes while remaining distinct. Throughout the study, my attention is focused on the argumentative procedures Spinoza adopts. This yields a close, internalist reading of the text where Spinoza effectively embraces substance monism. In conclusion to this study, I underscore to the originality of Spinoza’s argument for seventeenth century theories of substance. (shrink)

Spinoza's use of the phrase “sui iuris” in the Tractatus Politicus gives rise to the following paradox. On the one hand, one is said to be sui iuris to the extent that one is rational; and to the extent that one is rational, one will steadfastly obey the laws of the state. However, Spinoza also states that to the extent that one adheres to the laws of the state, one is not sui iuris, but rather stands under the (...) power [sub potestate] of the state . It seems, then, that to the extent that one is sui iuris, one will not, in fact, be sui iuris. In this paper, I offer an interpretation of Spinoza's notion of being sui iuris that enables us to overcome this paradox and sheds light on Spinoza's relationship to the republican tradition. I work towards this goal by distinguishing between two ways in which Spinoza uses the locution, which correspond to two different conceptions of power: potentia and potestas. This distinction not only allows us to save Spinoza from internal inconsistency, it also enables us to see one important way in which Spinoza stands outside of the republican tradition, since he conceives of liberty not as constituted by independence, or citizenship in a res publica, but as being sui iuris in the first sense described above: being powerful.

Despite Spinoza’s reputation as a thoroughgoing critic of teleology, in recent years a number of scholars have argued convincingly that Spinoza does not wish to eliminate teleological explanations altogether. Recent interpretative debates have focused on a more recalcitrant problem: whether Spinoza has the resources to allow for the causal efficacy of representational content. In this paper I present the problem of mental causation for Spinoza and consider two recent attempts to respond to the problem on (...) class='Hi'>Spinoza’s behalf. While these interpretations certainly shed some light on Spinoza’s account of cognitive economy, I argue that both fail to point the way out of the problem because they fail to differentiate between two forms of representation, one of which is causally efficacious, one of which is not. I close by suggesting that there is some reason to believe that Spinoza’s account of mind avoids some of the problems typically associated with mental causation. (shrink)

The aim of this paper is to clarify Spinoza’s views on some of the most fundamental issues of his metaphysics: the nature of God’s attributes, the nature of existence and eternity, and the relation between essence and existence in God. While there is an extensive literature on each of these topics, it seems that the following question was hardly raised so far: What is, for Spinoza, the relation between God’s existence and the divine attributes? Given Spinoza’s claims (...) that there are intimate connections between God’s essence and his existence – “God’s essence and his existence are one and the same”(E1p20) – and between God’s essence and the attributes – “By attribute I understand what the intellect perceives of substance, as constituting its essence” (E1d4), we would naturally expect that by transitivity, there is a significant relation between God’s existence and the attributes. Yet, as far as I know, there is little, if any, attempt in the existing literature to explicate such a relation, and it is one of my aims of this study to both raise the question and answer it. Eventually, I will argue that for Spinoza God is nothing but existence, and that the divine attributes are just fundamental kinds of existence, or, what is the same, as I will later argue, the intellect’s most fundamental and adequate conceptions of existence. In the first part of the paper I provide some background for Spinoza’s brief discussion in the TTP of God’s name and essence by studying the claims of Maimonides in the Guide of the Perplexed that God’s true essence is necessary existence, and that this essence is denoted by the ineffable Hebrew name of God, the Tetragrammaton (YHVH). In the second part of the paper I point out similar claims Spinoza presents in the TTP, and show how they respond to and echo Maimonides’ discussion in the Guide. In the third part, I examine Spinoza’s apparently conflicting claims in the Ethics about the relationship between God’s essence and existence. In some places Spinoza claims that God’s essence and existence are strictly identical (E1p10: “God’s essence his existence are one and the same”), but in other passages he makes the apparently much more modest claim that God’s essence involves existence (E1d1, E1p7d and E1p11d), which may lead one to believe that there is more to God’s essence than mere existence. I show that Spinoza’s understanding of the relation denoted by the Latin ‘involvit’ is consistent with the strict identification of essence and existence in God, and that Spinoza identifies God’s essence with self-necessitated existence, or eternity. Indeed, Spinoza’s understanding of eternity [aeternitas] as self-necessitated existence (E1d8) is one of the very few Spinozistic concepts that has no trace in Descartes. In this part I will also solve the long-standing problem of the sense in which the infinite modes can be called ‘eternal.’ In the fourth part I turn to the relation between the divine attributes and God’s existence and argue that, for Spinoza, the attributes are self-sufficient and adequate conceptions of existence. Finally, I will attempt to explain what brought Spinoza to deify existence. -/- Part I: “In that Day shall God be One, and his Name One”- Maimonides on God’s Name and Essence. -/- 1.1 Before we delve into the texts, let me suggest a few distinctions between various views on the issue of the relation between essence and existence in God. The view I suspect both Maimonides and Spinoza subscribe to can be termed the divine essence-existence Identity Thesis. -/- Identity Thesis (IT): God’s essence is existence and nothing but existence. We should distinguish the Identity Thesis from the much more common view according to which God’s essence contains existence, or (which I take to be roughly the same) that existence is one of the properties or perfections which constitute God’s essence. The latter view allows for the possibility (though it does not demand) that there is more to God’s essence than bare existence (e.g., God’s essence may include omniscience, omnipotence, etc.). I will term this view the divine essence-existence Containment Thesis. (shrink)

In this paper I discuss two related ideas and cross-reference them, as it were, on the common ground of the Spinozistic text. First, I want to construct a Spinozistic account of domestic violence and a Spinozistic response to such violence. This will involve attempting to explicate the phenomenon (or at least one aspect of it, to be defined) through the terms and conceptual structure of Spinoza's Ethics. Second, I want to discuss a feminist reading (interpretation) of Spinoza, that (...) of Luce Irigaray. The projects work together, as a better Spinozistic account requires a charitable reading of Spinoza to which Irigaray points the way. Irigaray will turn out to be more Spinozistic that Spinoza himself. In addition, the construction of a Spinozistic response to domestic violence will highlight the textual basis of Irigaray’s reading. It is hoped that this will contribute to making Irigaray’s reading accessible to philosophers trained in the analytic tradition. The undercurrent of both discussions will be an attempt to explicate and further what I take to be a shared moral insight in the late twentieth century, namely, that domestic violence, and particularly violence against women as wives and partners, is morally wrong.

People attribute resistance to bodies in Spinoza's physics. It's not always clear what they mean when they do this, or whether they are entitled to. This article clarifies what it would mean, and examines the evidence for attributing resistance. The verdict: there's some evidence, but not nearly as much as people think.

This essay contends that Spinoza provides a valuable analysis of the ‘‘affective’’damage to a social body caused by fear, anxiety, and ‘‘superstition.’’ Far from being primarily an external threat, this essay argues that terrorism and the promulgationof fear by the current administration in the United States pose a threat to internalsocial cohesion. The capacity to respond in constructive and ameliorative ways tocurrent global conflicts is radically undermined by amplifying corrosive relationshipsof anxiety, suspicion and hatred among citizens. Spinoza presents (...) a portrait of natural and political existence as deeply relational and ‘‘affective’’ such that human freedom and power depend upon the concern for the affective and passionatedispositions of human bodies and minds. In order for democracy, the power of themany, to exist effectively, the social body must be ruled by ‘‘joyful passions’’ rather than ‘‘sad passions,’’ which are destructive and debilitating by nature.

Through a radical new reading of the Theological Political Treatise, Dimitris Vardoulakis argues that the major source of Spinoza’s materialism is the Epicurean tradition that re-emerges in modernity when manuscripts by Epicurus and Lucretius are rediscovered. This reconsideration of Spinoza’s political project, set within a historical context, lays the ground for an alternative genealogy of materialism. Central to this new reading of Spinoza are the theory of practical judgment (understood as the calculation of utility) and its implications (...) for a theory of democracy that is resolutely positioned against authority.

The Introduction argues for the significance of Spinoza in contemporary philosophical, social and political debates. It also presents the main arguments presented by the contributors to this volume.

A common perception of Spinoza casts him as one of the precursors, perhaps even founders, of modern humanism and Enlightenment thought. Given that in the twentieth century, humanism was commonly associated with the ideology of secularism and the politics of liberal democracies, and that Spinoza has been taken as voicing a “message of secularity” and as having provided “the psychology and ethics of a democratic soul” and “the decisive impulse to… modern republicanism which takes it bearings by the (...) dignity of every man,” it is easy to understand how this humanistic image developed. Spinoza’s deep interest in, and extensive discussion of, human nature may have contributed to the emergence of this image as well. In this paper, I will argue that this common perception of Spinoza is mistaken and that Spinoza was in fact the most radical anti-humanist among modern philosophers. Arguably, Spinoza rejects any notion of human dignity. He conceives of God’s - and not man’s - point of view as the only objective perspective through which one can know things adequately, and it is at least highly questionable whether he allows for any genuine notions of human autonomy or morality. The notions of ‘humanism’ and ‘anti-humanism’ have been discussed extensively -mainly among continental philosophers - since the end of World War II. Because these notions carry a variety of historical, ideological, and philosophical meanings, it is important to provide at the outset at least a rudimentary clarification of my use of these two terms. By ‘humanism’ I mean a view which (1) assigns a unique value to human beings among other things in nature, (2) stresses the primacy of the human perspective in understanding the nature of things, and (3) attempts to point out an essential property of humanity which justifies its elevated and unique status. This definition of philosophical humanism has only little in common with the historical notion of Renaissance humanism, and seems to match quite well the common understanding of philosophical humanism suggested by current philosophical dictionaries and encyclopedias. This notion of humanism should be understood in contrast to two competing positions. On the one hand, in contrast to the theocentric position that considers humanity to be radically dependent upon God, humanism affirms at least some degree of human independence. On the other hand, in contrast to the naturalist position which endorses the scientific examination of human beings just like any other objects in nature, humanists affirm the existence of a metaphysical and moral gulf between humanity and nature. This gulf assigns a special value to humanity and does not allow us to treat human beings like any other things in nature. For many humanists the nature/humanity gulf does not allow the application of the methods of natural sciences to the disciplines of the humanities. Humanism does not begin with modernity. In order to see how far back we can trace this position, we may recall Protagoras’ saying: “Man is the measure of all things, of things that are, that they are, and of things that are not, that they are not.” In modern philosophy, the humanistic position had regained dominant status since the Renaissance, and variants of this position were vigorously argued for by prominent thinkers such as Pico della Mirandola, Descartes, Leibniz, Kant, Fichte, and finally, Hegel. In this paper, I will argue that Spinoza was a foe, and not a friend, of this tradition. I suggest that, in contrast to these humanist philosophers, Spinoza considers man as a marginal and limited being in nature, a being whose claims and presumptions far exceed its abilities. “To what length will the folly of the multitude not carry them?.... [T]hey imagine Nature to be so limited that they believe man to be his chief part.” Arguably, Spinoza locates the origin of our most fundamental metaphysical and ethical errors in a human hubris which not only tries to secure humanity an exceptional place in nature but also attempts to cast both God and nature in its own human image.

The German text of Cohen’s Spinoza on State & Religion, Judaism & Christianity (Spinoza über Staat und Religion, Judentum und Christentum) first appeared in 1915 in the Jahrbuch für jüdische Geschichte und Literatur. Two years before, in the winter of 1913, Cohen taught a class and a seminar on Spinoza’s Theological-Political Treatise at the Hochschule für die Wissenschaft des Judentums. This was Cohen’s first semester at the Hochschule, after retiring from more than thirty years of teaching at (...) the University of Marburg. Cohen’s fame at the time was at its zenith, and his move to the Hochschule was a cause for celebration and excitement. According to the testimony of some students who attended the Tractatus Theologico-Politicus seminar, Cohen left no place for any expression of dissent (regrettably, the academy frequently encourages such authoritarian behavior). The text of Spinoza on State, which was the product of this seminar, still bears the marks of this “didactic” attitude. It is bombastic and feebly argued. Thus, in one moment of emotional crescendo in the text, we can literally hear Cohen shout: When Spinoza, with merciless severity, makes his own nation the object of contempt – at the time that Rembrandt lived on the same street and immortalized the ideal type of the Jew - no voices rises in protest against this humanly incomprehensible betrayal. Such patriotic rhetoric is quite typical of Cohen’s Spinoza on State, as the work reads more like a series of rants against the devil incarnated (“the demonic spirit of Spinoza”) in the figure of the traitor from Amsterdam than like a sustained and serious philosophical polemic. From time to time, one can observe hints of critical arguments, but hardly any are fleshed out. The text is also replete with rudimentary factual and interpretative errors. Thus, when Cohen argues that Spinoza traces his pantheism to Jewish sources, Cohen erroneously cites Spinoza’s reference in E2p7s to “some of the Hebrews [quidam Hebraeorum]” who argued for the identity of Sekhel, Maskil, and Muskal (the Intellect, the Intellecting Subject, and the Intellected Object) – a Maimonidean doctrine that has nothing to do with pantheism – while the text Cohen clearly had in mind was Spinoza’s claim, in Letter 73, that the traditions (traditionibus) of the “ancient Hebrews [antiquis Hebraeis]” agree with Spinoza’s claim that “all things are in God.” Similarly, and on the very same page, Cohen ascribes to Spinoza the claim that “the God of the Old Testament is only a body,” a claim which is nowhere to be found in Spinoza’s works, and which can be inferred from Spinoza’s text only through a patent fallacy. If I may add one last example, consider the following passage from Cohen’s Spinoza on State: [For Spinoza] divine law is grounded in our mind. Yet this does not mean that our mind bears responsibility for producing and obeying the law. Instead, it means that, by definition, the human mind and God are identical, inasmuch as He exists in the human mind. Hardly any claim in this brief passage is correct. Yet, what is most striking is Cohen’s derivation of the identity of God and the human mind from the claim that God exists in the human mind. If I exist in North America, this obviously does not imply that I am identical to North America (there are, for example, a couple of North American porcupines and alligators that are distinct from me). What rule of inference Cohen sought to employ in this argument, and how this impressive inference of the identity of God and the human mind is supposed to square with Cohen’s view of Spinoza as a pantheist – i.e., as considering the physical nature to be divine – is beyond my grasp. Instead of tracking down the dozens of crude errors and fallacies in Cohen’s text, I would like to concentrate here on one crucial issue: Cohen’s critique of Spinoza’s pantheism. By doing this, I will have to pass silently over a couple of surprising agreements between the two figures, such as the (false) claim that all of the prophets of the Hebrew Bible taught the same universal and simple morality. My discussion of pantheism will be divided into two sections. In the first, I will examine Cohen’s understanding of Spinoza’s pantheism. In the second, I will briefly examine the historical validity of Cohen’s claim that pantheism is a Christian doctrine, diametrically opposed to Judaism. (shrink)

This essay traces the rather consistent essentialist thread that runs through the whole Short Treatise. This allows us not only to better understand the work itself but also to obtain a firmer grasp of the nature of Spinoza’s entire philosophical enterprise. In many ways, the essentialism we find in the Short Treatise is in line with Spinoza’s mature thought; but there are also significant differences, and discerning them throws light on the development of Spinoza’s philosophy.

The aim of this article is twofold: to provide a valid account of Spinoza’s theory of fictitious ideas, and to demonstrate its coherency with the overall modal metaphysics underpinning his philosophical system. According to Leibniz, the existence of romances and novels would be sufficient to demonstrate, against Spinoza’s necessitarianism, that possible entities exist and are intelligible, and that many other worlds different from ours could have existed in its place. I argue that Spinoza does not actually need (...) to resort to the notion of possible entities in order to explain the incontrovertible existence of fictions and fictitious ideas. In order to demonstrate this, I first show how, according to Spinoza, true ideas of nonexistent things need not be regarded as fictitious ideas. Then, I will show by which means Spinoza can justify the real existence of fictions and fictitious ideas in the human mind through our present knowledge of actually existing things, to conclude that fictitious ideas neither add anything to what we already know of things, nor do they increase the extent of the existing conceivable reality by demanding the existence of possible non-actualised entities.

Samuel Clarke was one of Spinoza's earliest and fiercest opponents in England. I uncover three related Clarkean arguments against Spinoza's metaphysic that deserve more attention from readers today. Collectively, these arguments draw out a tension at the very heart of Spinoza's rationalist system. From the conjunction of a necessary being who acts necessarily and the principle of sufficient reason, Clarke reasons that there could be none of the diversity we find in the universe. In doing so, Clarke (...) potentially reveals an inconsistent triad in Spinoza. Responses to this inconsistency map onto a deep division in the contemporary Spinoza literature. I conclude that Clarke's arguments provide a new approach to the recently revived debate over acosmic interpretations of Spinoza and point to new interpretive possibilities. (shrink)

Friedrich Nietzsche was Less Well-Read in the history of philosophy than were many of his peers in the pantheon, whether Hegel before him or Heidegger after, but he was not for that reason any less hesitant to pronounce judgment on the worth of the other great philosophers: Plato was “boring”; Descartes was “superficial”; Hobbes, Hume, and Locke signify “a debasement and lowering of the concept of ‘philosophy’ for more than a century”; Kant was an “idiot” and a “catastrophic spider,” etc.1 (...) Against this overarching trend of negativity, his uncharacteristically positive response to one thinker, a thinker who initially appears to us as quite different from him, is all the more surprising.

Spinoza reasons about impossibilities on a regular basis. But he also says they're unthinkable and that reasoning is a mental process. How can he do this? The paper defends a linguistic account of counterpossible inferences in Spinoza's geometrical method.

In his groundbreaking work of 1969, Spinoza's Metaphysics: An Essay in Interpretation, Edwin Curley attacked the traditional understanding of the substance-mode relation in Spinoza, which makes modes inhere in the substance. Curley argued that such an interpretation generates insurmountable problems, as had been already claimed by Pierre Bayle in his famous entry on Spinoza. Instead of having the modes inhere in the substance Curley suggested that the modes’ dependence upon the substance should be interpreted in terms of (...) (efficient) causation, i.e., as committing Spinoza to nothing over and above the claim that the substance is the (efficient) cause of the modes. These bold and fascinating claims generated one of the most important scholarly controversies in Spinoza scholarship of the past thirty-five years. In this chapter I argue against Curley’s interpretation and attempt to reestablish the traditional understanding of Spinozistic modes as inhering in God and as predicated of God. I also criticize Curley’s philosophical motivation for suggesting this interpretation. I do believe, however, that Curley is right about the existence of an intimate connection between the substance-mode relation and causation in Spinoza. In the next chapter I will study the notion of ‘immanent cause’, which merges efficient causality and inherence. I will clarify the relation between immanent, efficient and material causation, and show where precisely Spinoza diverged from the traditional Aristotelian taxonomy of causes. In the second chapter I also discuss the German Idealists’ view of Spinoza as an ‘acosmist’. Under this interpretation Spinoza was a modern reviver of Eleatic monism, who allegedly asserts the mere existence of God, and denies the reality of the world of particular things. Spinozistic modes - according to this reading - are nothing but passing and unreal phenomena. Though this view of Spinoza as an ‘acosmist’ can be supported by some lines in Spinoza’s thought, I believe it should be rejected since it is not consistent with some of the most central doctrines of the Ethics. In the final part of the second chapter I discuss the relation between modes and the attributes under which they fall, and suggest a terminological distinction between a ‘mode of God’ (i.e., a mode under all attributes) and a ‘mode of an attribute’ (i.e., a mode under a specific attribute), a distinction which can help us avoid some common confusions in the treatment of the issue.

In the current paper I rely on two outstanding studies. The one, by Warren Zev Harvey, draws a portrait of Spinoza as Maimonidean, stressing the continuity between Maimonides and Spinoza on the issue of morality and the highest good. The other is the magisterial study by Steven Shmuel Harvey of the reception of the Nicomachean Ethics in medieval Jewish philosophy, from its being subject to almost complete indifference in the period before Maimonides until it became “the best known (...) and most cited work of Aristotle” in sixteenth-century Jewish philosophy. In the first part of this paper I will discuss some main junctions in the medieval Jewish reception of the notion of the highest good. This discussion will be cursory and will mostly focus on matters that will help us approach Spinoza’s views on the issue, views which will be examined closely in the second part of the paper.

In this essay I consider what grounds Spinoza’s defense of the freedom to philosophize, considering why Spinoza doesn’t think that we should attempt to snuff out irrationality and dissolution with the law’s iron fist. In the first section I show that Spinoza eschews skeptical, pluralistic, and rights-based arguments for toleration. I then delineate the prudential, anticlerical roots of Spinoza’s defense, before turning in the final section to consider just how far and when toleration contributes to the (...) guiding norms of governance: peace and empowerment. Once we see how the defense of toleration is anchored in these norms, we form a clearer picture of Spinoza as a liberal perfectionist for whom the bounds of political toleration depends on pragmatic and circumstance-specific assessments of what conduces to the flourishing of the state. This will help to illuminate what is distinctive—and, perhaps, distinctively commendable—about Spinoza’s form of liberalism. (shrink)

In the pre-history of the concept of recognition Spinoza’s social philosophy deserves a special place. Although we rarely think of Spinoza as a social philosopher, Spinoza understood well the ways in which individual subjectivity is shaped by the social forces. I will argue that Spinoza offers a mechanism to understand the way in which recognition works, in order to untangle the web of affect, desire and ideas, which support the recognitions and misrecognitions at the foundation of (...) social life. Spinoza sets out this mechanism in Book Three of the Ethics, but his extended example of the first Hebrew Kingdom in the Theological-Political Treatise, shows how he applied his theory of social recognition to the great problem of his times – the debate between faith and reason, and the need to unify a commonwealth. Social unity based on shared religion, for Spinoza, could be powerful, though not so powerful as democracy. Only through understanding Spinoza’s views of social subjectivization can we understand why. (shrink)
