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.

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.

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.

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.

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.

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.

“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.

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)

: 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)

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.

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.

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)

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.

: 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)

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.

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)

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.

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 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)

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.

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.

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 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.

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.

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.

This collection, the first broadly interdisciplinary volume dealing with Spinozan thought, asserts the importance of Spinoza’s philosophy of immanence for contemporary cultural and philosophical debates.

Spinoza's account of belief entails that if A has two ideas, p and q, with incompatible content, A believes that p if the idea of p is stronger than the idea of q. This seems to leave little space for dominant non-beliefs, or cases in which there is discord between one's beliefs and one's affective-behavioral responses. And yet Spinoza does allow for two classes of dominant non-beliefs: efficacious fictions [fictiones] and ideas that conduce to akrasia. I show how (...) Spinoza can account for dominant non-beliefs within his model of cognition by distinguishing between the doxastic and the affective powers of ideas and by suggesting that doxastic power is best understood diachronically. While other scholars have stressed the elegance of Spinoza's account of ideas, this paper highlights the sophistication and flexibility of his account. (shrink)

In the final chapter of the Tractactus Theologico-Politicus , Spinoza declares that “the purpose of the state is, in reality, freedom.” While this remark obviously purports to tell us something important about Spinoza’s conception of the civitas , it is not clear exactly what is revealed. Recently, a number of scholars have interpreted this passage in a way that supports the view that Spinoza was a liberal for whom civic norms are rather more modest than the freedom (...) of the Ethics . Against this view, I provide an interpretation of Spinoza’s account of civil liberation that enables us to view the political writings as an extension of his larger ethical enterprise. Specifically, I show that, according to Spinoza, the state can promote robust liberty in a variety of ways, not least by influencing the behavioral patterns and affective dispositions of its citizens.

The notion of divine love was essential to medieval Christian conceptions of God. Jewish thinkers, though, had a much more ambivalent attitude about this issue. While Maimonides was reluctant to ascribe love, or any other affect, to God, Gersonides and Crescas celebrated God’s love. Though Spinoza is clearly sympathetic to Maimonides’ rejection of divine love as anthropomorphism, he attributes love to God nevertheless, unfolding his notion of amor Dei intellectualis at the conclusion of his Ethics. But is this a (...) legitimate notion within his system? In the first part of this article, I will explain some of the problems surrounding this notion, and then turn, in the second part, to consider two unsatisfactory solutions. In the third part, I will attempt to rework Spinoza’s amor Dei intellectualis from his definitions of love and the other affects in part three of the Ethics. In the fourth part, I will examine closely how Spinoza tweaks his definition of love in order to allow for the possibility of divine intellectual love, and conclude by trying to explain what motivated this move.

In this paper, I maintain—contrary to those commentators who regard him as a principled republican—that at the core of Spinoza’s political theory is an instrumental, rather than an intrinsic, defense of democratic procedures. Specifically, Spinoza embraces democratic decision procedures primarily because they tend to result in better decisions, defined relative to a procedure-independent standard of correctness or goodness. In contemporary terms, Spinoza embraces an epistemic defense of democracy. I examine Spinoza’s defense of collective governance, showing not (...) only how it differs from other accounts of his time but also how it might contribute to current debates about the epistemic standing of popular governing bodies. In the opening section I defend the thesis that has been contested in recent years that Spinoza was, in fact, a consistent democrat. The second section focuses on procedural (i.e., intrinsic) defenses of democracy, paying particular attention to the republican version of proceduralism that was prominent in Spinoza’s time. And in the final section I present my case for reading Spinoza as an epistemic democrat, comparing his epistemic defense with contemporary versions. What we find are not only striking anticipations of contemporary arguments, but also largely neglected lines of argumentation that reveal both the potential epistemic advantages and disadvantages of democracy.

Spinoza distinguishes between causation that is external, as in A causing B where A is external to B, and causation that is internal, where C causes itself (causa sui), without any involvement of anything external to C. External causation is easy to understand, but self causation is not. This note explores an approach to self-causation based upon Gödelian undecidability and draws upon ideas from an earlier study of Gödel’s proof and the quantum measurement problem (Zwick, 1978).

In Ethics 1p5, Spinoza asserts that “In Nature there cannot be two or more substances of the same nature or attribute”. This claim serves as a crucial premise in Spinoza’s argument for substance monism, yet Spinoza’s demonstration of the 1p5 claim is surprisingly brief and appears to have obvious difficulties. This paper answers the principle difficulties that have been raised in response to Spinoza’s argument for 1p5. The key to understanding the 1p5 argument lies in a (...) proper understanding of the substance-attribute relationship and the principles of metaphysical individuation that Spinoza accepts. (shrink)

Like any broad narrative about the history of ideas, this one involves a number of simplifications. My hope is that by taking a closer look Spinoza's notorious remarks on animals, we can understand better why it becomes especially urgent in this period as well as our own for philosophers to emphasize a distinction between human and nonhuman animals. In diagnosing the concerns that give rise to the desire to dismiss the independent purposes of animals, we may come to focus (...) on a new aspect of what needs to change about contemporary thinking on species divisions. In what follows, I will bring out Spinoza's contradictory and ambivalent remarks pertaining to the specific differences between humans and animals. It is my suspicion that this ambivalence continues to plague us today. Like Spinoza, we want to say that humans are like and unlike animals. As a simply descriptive claim, it may be true and innocuous. Yet, the way we affirm our proximity and distance from nonhuman animals requires careful attention. Spinoza viewed this proximity as a source of danger. We might do well to emphasize, with thinkers such as Donna Haraway (2003),how our proximity and difference are also sources of pleasure and power, both to be able to enjoy the affectionate bond that can often develop between humans and our animal companions but also to quell the anxiety that might encourage us to exploit and abuse them.

Negri celebrates a conception of democracy in which the concrete powers of individual humans are not alienated away, but rather are added together: this is a democracy of the multitude. But how can the multitude act without alienating anyone’s power? To answer this difficulty, Negri explicitly appeals to Spinoza. Nonetheless, in this paper, I argue that Spinoza’s philosophy does not support Negri’s project. I argue that the Spinozist multitude avoids internal hierarchy through the mediation of political institutions and (...) not in spite of them; nor do these institutions merely emanate from the multitude as it is, but rather they structure, restrain and channel its passions. In particular, the required institutions are not those of a simple direct democracy. There may be other non-Spinozist arguments on which Negri can ground his theory, but he cannot legitimately defend his conception of the democratic multitude by appeal to Spinoza. (shrink)

At the opening of Spinoza’s Ethics, we find the three celebrated definitions of substance, attribute, and God: E1d3: By substance I understand what is in itself and is conceived through itself, i.e., that whose concept does not require the concept of another thing, from which it must be formed [Per substantiam intelligo id quod in se est et per se concipitur; hoc est id cujus conceptus non indiget conceptu alterius rei, a quo formari debeat]. E1d4: By attribute I understand (...) what the intellect perceives of a substance, as constituting its essence [Per attributum intelligo id, quod intellectus de substantia percipit, tanquam ejusdem essentiam constituens]. E1d6: By God I understand a being absolutely infinite, that is, a substance consisting of an infinity of attributes, of which each one expresses an eternal and infinite essence We are accustomed to think of these paramount definitions as a fixed and settled formulation of the core of Spinoza’s metaphysics, but if we look at the development of Spinoza’s thought, the picture we get is quite different. In the early drafts of the Ethics and in his early works, Spinoza seems to have experimented with various conceptualizations of the relations between substance, attribute, and God. Some of Spinoza’s works make barely any use of the notions of substance and attribute, and the testimony of Spinoza’s letters suggests that, at a certain stage in his philosophical development, the concept of attribute may have been put on the back burner, if not completely dropped. Indeed, another closely related concept—accident [accidens]—was fated to be pulled out of the system (and for good reasons ). The final version of the Ethics makes hardly any use of this notion, but Spinoza’s letters show that in early drafts of the Ethics he used the term ‘accident’ to refer to what cannot be or be conceived without substance. In this paper I will attempt to provide a brief outline of the genealogy of Spinoza’s key metaphysical concepts. This genealogy, like any other, can help us to reexamine and reconsider what seems to us natural, stable and obvious. In the first part of the paper, I rely on Spinoza’s letters to trace the development of his definitions of substance and attribute in the early drafts of the Ethics. The letters, whose dates are more or less established, also provide a temporal grid for our subsequent discussions. The second part surveys Spinoza’s discussion and conceptualization of substance and attributes in the Treatise on the Emendation of the Intellect, the Theological-Political Treatise (1670), and briefly, Spinoza’s 1663 book on Descartes’ Principles of Philosophy, and its appendix on Metaphysical Thoughts, the Cogitata Metaphysica. The third part of the paper is dedicated to Spinoza’s understanding of substance and attribute in the Short Treatise on God, Man, and His Well-Being. I conclude with some remarks on the stability of Spinoza’s final position on the issue, as expressed in the published version of the Ethics . (shrink)

Spinoza ’s letter of June 2, 1674 to his friend Jarig Jelles addresses several distinct and important issues in Spinoza ’s philosophy. It explains briefly the core of Spinoza ’s disagreement with Hobbes’ political theory, develops his innovative understanding of numbers, and elaborates on Spinoza ’s refusal to describe God as one or single. Then, toward the end of the letter, Spinoza writes: With regard to the statement that figure is a negation and not anything (...) positive, it is obvious that matter in its totality, considered without limitation [indefinitè consideratam], can have no figure, and that figure applies only to finite and determinate bodies. For he who says that he apprehends a figure, thereby means to indicate simply this, that he apprehends a determinate thing and the manner of its determination. This determination therefore does not pertain to the thing in regard to its being [esse]; on the contrary, it is its non-being [non-esse]. So since figure is nothing but determination, and determination is negation [Quia ergo figura non aliud, quam determinatio, et determinatio negatio est], figure can be nothing other than negation, as has been said. Arguably, what is most notable about this letter is the fate of a single subordinate clause which appears in the last sentence of this passage: et determinatio negatio est. That clause was to be adopted by Hegel and transformed into the slogan of his own dialectical method: Omnis determinatio est negatio. Of further significance is the fact that, while Hegel does credit Spinoza with the discovery of this most fundamental insight, he believes Spinoza failed to appreciate the importance of his discovery. The issue of negation and the possibility of self-negation stand at the very center of the philosophical dialogue between the systems of Spinoza and Hegel, and in this paper I will attempt to provide a preliminary explication of this foundational debate between the two systems. In the first part of the paper I will argue that the “determination is negation” formula has been understood in at least three distinct senses among the German Idealists, and as a result many of the participants in the discussion of this formula were actually talking past each other. The clarification of the three distinct senses of the formula will lead, in the second part of the paper, to a more precise evaluation of the fundamental debate between Spinoza and Hegel regarding the possibility of self-negation. In this part I will evaluate the validity of each interpretation of the determination formula, and motivate the positions of the various participants in the debate. (shrink)

Through an examination of his remarks on Genesis, chapters 2–3, I will demonstrate that Spinoza’s argument for sexual inequality is not only an aberration,but a symmetrical inversion of a view he propounds, albeit implicitly, in his Ethics. In particular, “the black page” of his Political Treatise ignores, along with the intellectual capacities of women, the immeasurable benefits of affectionate partnership between a man and a woman that he extols in his retelling of the Genesis narrative. If the doctrine of (...) the black page maintains that it is the dependency of wives upon their husbands that explains their weakness and justifies their exclusion from formal roles in politics, his unusual narrative of the Fall illustrates that it is precisely Adam's lack of appreciation of his need for his wife that accounts for his imbecility.

This essay examines Elizabeth Grosz's provocative claim that feminist and anti-racist theorists should reject a politics of recognition in favor of "a politics of imperceptibility." She criticizes any humanist politics centered upon a dialectic between self and other. I turn to Spinoza to develop and explore her alternative proposal. I claim that Spinoza offers resources for her promising politics of corporeality, proximity, power, and connection that includes all of nature, which feminists should explore.

This chapter will discuss Spinoza’s critique of free will, though our brief study of this topic in the first part of the chapter will aim primarily at preparing us to address the main topic of the chapter, which is Spinoza’s explanation of the reasons which force us to believe in free will. At times, Spinoza seems to come very close to asserting the paradoxical claim that we are not free to avoid belief in free will. In the (...) second part of the chapter I will closely examine Spinoza’s etiological explanation of how we come to form the belief in free will. In the third part, I will raise and respond to a crucial objection to Spinoza’s explanation of the formation of our belief in free will. I will then turn to examine Fichte’s intriguing claim that Spinoza’s position on the issue of free will suffers from an internal contradiction, as evinced in Fichte’s suggestive remark: “Spinoza could not have been convinced of his own philosophy. He could only have thought of it; he could not have believed it [Er konnte seine Philosphie nur denken, nicht sie glauben].”. (shrink)

In the Tractatus Theologico-Politicus (TTP), Spinoza argues that an individual’s natural right extends as far as their power. Subsequently, in the Tractatus Politicus (TP), he offers a revised argument for the same conclusion. Here I offer an account of the reasons for the revision. In both arguments, an individual’s natural right derives from God’s natural right. However, the TTP argument hinges on the claim that each individual is part of the whole of nature (totius naturae), and for this reason (...) inherits part of the natural right of that whole. Using several analogous cases from the Ethics, I show that this form of argument from division is not compatible with Spinoza’s considered metaphysical views. The revised argument, by contrast, avoids the pitfalls of his earlier efforts. It also better reveals the deep roots by which the monistic metaphysics of the Ethics feeds into Spinoza’s conception of natural right. (shrink)

Although the works of the authors of the Golden Age of Latin Literature play an important formative role for Early Modern philosophers, their influence in Early Modern thought is, nowadays, rarely studied. Trying to bring this topic to light once again and following the seminal works of Kajanto (1979), Proietti (1985) and Akkerman (1985), I will target Spinoza’s Latin sources in order to analyze their place in his philosophy. On those grounds, I will offer an overview of the problems (...) of the reception of classical literature in Early Modernity and then dwell on the particular case of Ovid and Spinoza. The present paper will argue that although Spinoza’s references to Ovid fill a rhetorical purpose as suggested by the existing literature, these mentions have a prior philosophical motivation. That is, the references in the Ethics are not merely illustrative; instead, they indicate that Spinoza acknowledges Ovid’s beliefs about human experiences and deliberately elaborates on Ovid’s view to construct and defend his own theses. To this end, the paper will analyze some citations mapped by Proietti (1985) and add a new one in an attempt to enlarge the list of places and topics that merit further investigation. To conclude, I will point out how the references to Ovid are part of Spinoza’s own defense of the powers of imagination. (shrink)

Spinoza’s philosophy of mind is thought to lack a serious account of consciousness. In this essay I argue that Spinoza’s doctrine of ideas of ideas has been wrongly construed, and that once righted it provides the foundation for an account. I then draw out the finer details of Spinoza’s account of consciousness, doing my best to defend its plausibility along the way. My view is in response to a proposal byEdwin Curley and the serious objection leveled against (...) it by Margaret Wilson and Jonathan Bennett. (shrink)
