Spinoza on Composition,Causation, and the Mind's Eternity

Spinoza's doctrine of the eternity of the mind is often understood as the claim that the mind has a part that is eternal. I appeal to two principles that Spinoza takes to govern parthood and causation to raise a new problem for this reading. Spinoza takes the composition of one thing from many to require causal interaction among the many. Yet he also holds that eternal things cannot causally interact, without mediation, with things in duration. So the human mind, since it is the idea of a body existing in duration, cannot have an eternal part. In order to solve this problem, I propose an aspectual reading of Spinoza's doctrine of the eternity of the mind: the mind itself is eternal, under one of its aspects.     

Spinoza on the Limits of Explanation

Commentators standardly ascribe to Spinoza a belief in an exceptionless conceptual closure of mental and physical realms: no intention can allow us to understand a bodily movement, no bodily injury can make intelligible a sensation of pain. This counterintuitive doctrine, most often now referred to as Spinoza's 'attribute barrier', has weighty repercussions for his views on intelligibility, nature of the mind, identity, and causality. I argue against the standard reading of the doctrine, by showing that it produces an inconsistent epistemological picture, contradicting Spinoza's theory of mind and his commitment to universal intelligibility. The alternative account I propose is also philosophically more compelling and plausible as an account of thought in its essential intentionality.     

Spinoza on essence and ideal individuation

My project in this paper is to fill a gap in Spinoza's theory of metaphysical individuation. In a few brief passages of the Ethics, Spinoza manages to explain his views on the nature of composition and the part-whole relation, the metaphysical facts which ground the individuation of simple bodies and the extended individuals they compose, and the persistence of one and the same individual through time and mereological change. Yet Spinoza nowhere presents a corresponding account of the individuation of simple ideas, or the minds such ideas compose. While it is initially tempting to locate the details of such an account in Spinoza's views on the relation between the mental and physical domains, I argue here that such approaches fail, in conflicting with Spinoza's insistence that the mental and the physical are conceptually and explanatorily independent. By contrast, I show that for Spinoza, each idea essentially possesses the property of affirming the existence of its object, and that such properties are well-suited to serve as the principle of ideal individuation Spinoza never explicitly provided.     

Shoemaker's Analysis of Realization: A Review

Sydney Shoemaker has been arguing for more than a decade for an account of the mind–body problem in which the notion of realization takes centre stage. His aim is to provide a notion of realization that is consistent with the multiple realizability of mental properties or events, and which explains: (i) how the physical grounds the mental; and (ii) why the causal work of mental events is not screened off by that of physical events. Shoemaker's proposal consists of individuating properties in terms of causal powers, and defining realization as a relation of inclusion between sets of causal powers. Thus, as the causal powers that define a mental property are a subset of the causal powers that characterize a physical property, it can be said that physical properties realize mental properties. In this paper we examine the physicalist credentials of Shoemaker's mind–body theory in relation to three important issues: the direction of the relation of dependence that the theory is committed to; the possibility of mental properties existing without being anchored by physical properties; and the compatibility of the theory with the causal closure of the physical world. We argue that Shoemaker's theory is problematic in all three respects. After that we consider whether the theory should count as a mind–body theory at all, given that it seems to be committed to a distorted view of mental properties.     

Two Kinds of Definition in Spinoza's Ethics

Spinoza scholars have claimed that we are faced with a dilemma: either Spinoza's definitions in his Ethics are real, in spite of indications to the contrary, or the definitions are nominal and the propositions derived from them are false. I argue that Spinoza did not recognize the distinction between real and nominal definitions. Rather, Spinoza classified definitions according to whether they require a priori or a posteriori justification, which is a classification distinct from either the real/nominal or the intensional/extensional classification. I argue that Spinoza uses both a priori and a posteriori definitions in the Ethics and that recognizing both types of definitions allows us to understand Spinoza's geometric method in a new way. We can now understand the geometric method as two methods, one resulting in propositions that Spinoza considers to be absolutely certain and another resulting in propositions that Spinoza does not consider certain. The latter method makes use of a posteriori definitions and postulates, whereas the former method uses only a priori definitions and axioms.     

Structural causality in Spinoza's Ethics

In this paper, I argue that Spinoza's claim at E1P15 that “Whatever is, is in God, and nothing can be or be conceived without God” remains exegetically troubling. Briefly noting some unresolved difficulties with the two dominant interpretations of Spinoza's account of the relationship between finite modes and God (these being the inherence and causal dependence readings), I move to claim that there is a third, neglected reading available which deserves consideration. I argue that, perhaps surprisingly, Althusser's notion of “structural causality,” putatively derived from Spinoza himself, can be used to construct this reading. Althusser's original notion of “structural causality” is explained and clarified further, its advantages outlined over competing readings of Spinoza, and exegetical evidence for its applicability to Spinoza is then produced.     

Spinoza's Essentialist Model of Causation

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 Suárez 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.     

Part-Whole Physicalism and Mental Causation

A well-known ``overdetermination'argument aims to show that the possibility of mental causes of physical events in a causally closed physical world and the possibility of causally relevant mental properties are both problematic. In the first part of this paper, I extend an identity reply that has been given to the first problem to a property-instance account of causal relata. In the second, I argue that mental types are composed of physical types and, as a consequence, both mental and physical types may be causally relevant with respect to the same physical effect, contrary to the overdetermination argument. In further sections, I argue that mental types have causal powers, consider some objections and reject an alternative version of part-whole physicalism. Throughout I assume that causal relata are tropes and property types are classes of tropes.     

Can Western Monotheism Avoid Substance Dualism?

The problem of divine agency and action is analogous to the problem of human agency and action: How is such agency possible in the absence of a dualistic causal interaction between disparate orders of being? This paper explores nondualistic accounts of divine agency that assert the following: (1) physical monism, (2) antireductionism, (3) physical realization, and (4) divine causal realism. I conclude that a robustly causal deity is incompatible with nonddualism's affirmation of physical monism. Specifically, I argue the incoherence of nondualistic strategies that advocate divine information transfer without energy transfer or the divine downward causation of physical events. Furthermore, I claim that the principle of explanatory exclusion makes any nondualistic, noninterventionist account of divine agency highly dubious. Finally, I suggest that Judaism, Christianity, and Islam can avoid a causally inert deity only if they are willing to deny the current presumption of the causal closure of the physical.     

Reply to Nadler: Spinoza and the metaphysics of suicide

Steven Nadler has argued that Spinoza can, should, and does allow for the possibility of suicide committed as a free and rational action. Given that the conatus is a striving for perfection, Nadler argues, there are cases in which reason guides a person to end her life based on the principle of preferring the lesser evil. If so, Spinoza’s disparaging statements about suicide are intended to apply only to some cases, whereas in others (such as the case of Seneca) he would grant that suicide is dictated by reason. Here, I object to Nadler’s interpretation by showing that it conflicts with Spinoza’s metaphysical psychology. Even given Nadler’s interpretation of the conatus doctrine, the possibility that reason could guide a person to commit suicide is incompatible with the conatus of the mind. Spinoza holds that the mind cannot contain an adequate idea ‘that excludes the existence of our body’ (E3p10). Yet, as I argue, in order for reason to guide a person voluntarily to end her life, she would need to have an adequate idea representing her death – an idea that excludes the existence of her body. For this reason, Spinoza's system rules out the possibility of rational suicide.     

Cody's categories

Of the two main interpretations of Spinoza's theory of the identity of the attributes, in particular those of Thought and Extension, the objective interpretation is now almost universally preferred to the subjective. Rejection of the subjective interpretation, according to which the attributes are merely our ways of cognizing a reality whose real essence remains unknown, is certainly justified, but the objective theory comes too near to replacing the identity by a mere correlation of différents to be quite satisfactory. Is it not better to say that Thought and Extension represent two complementary conceptions of reality which are both correct? Yes, but in saying so some commentators ascribe to mind, as Spinoza conceives it, an unplausibly abstract status. An alternative proposal is made as to a way in which Spinoza might be right in essentials, though it requires that a certain tension in Spinozism as to the nature of body be resolved in a particular direction.     

Fixing Descartes: Ethical Intellectualism in Spinoza's Early Writings

This paper aims at reconstructing the ethical issues raised by Spinoza's early Treatise on the Emendation of the Intellect. Specifically, I argue that Spinoza takes issue with Descartes’ epistemology in order to support a form of “ethical intellectualism” in which knowledge is envisaged as both necessary and sufficient to reach the supreme good. First, I reconstruct how Descartes exploits the distinction between truth and certainty in his Discourse on the Method. On the one hand, this distinction acts as the basis for Descartes’ epistemological rules while, on the other hand, it implies a “morale par provision” in which adequate knowledge is not strictly necessary to practice virtue. Second, I show that Spinoza rejects the distinction between truth and certainty and thus the methodological doubt. This move leads Spinoza to substitute the Cartesian Cogito with the idea of God as the only adequate standard of knowledge, through which the mind can attain the rules to reach the supreme good. Third, I demonstrate that in the Short Treatise Spinoza develops this view by equating intellect and will and thus maintaining that only adequate knowledge can help to contrast affects. However, I also insist that Spinoza's early epistemology is unable to explain why human beings drop conceive of the idea of God inadequately. Thus, I suggest that in his later writings Spinoza accounts for the insufficiency of adequate knowledge in opposing the power of the imagination and passions by reconnecting the nature of ideas with the mind's conatus.     

A Queer Supplement: Reading Spinoza after Grosz

This article critiques Elizabeth Grosz's understanding that queer theory is unproductive insofar as it disrupts the specific identities of gay and lesbian. Reconsidering ideas about desire, the body, and identity that Grosz takes from Gilles Deleuze's work on Friedrich Nietzsche and Baruch Spinoza, this essay argues that, despite her productive reworking of homophobia in terms of “active” and “reactive” forces, Grosz's application of Spinoza is only partial. Focusing on Spinoza's evaluation of bodies, the essay both critiques Grosz's approach to experimental desire and observes Spinozist preoccupations in order to talk about the experimental body. It concludes that if Grosz were to attend more seriously to the Spinozist imperative to analyze a body in terms of its capabilities—that is, its power to be affected—the epistemological basis of her argument would change. It would be difficult to dismiss the plurality and sensibility of a queer body or its challenge to lesbian and gay as the source of a primary identity.     

The Distinction between Reason and Intuitive Knowledge in Spinoza's Ethics

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

Spinoza on the Essences of Modes

This paper examines some aspects of Spinoza's metaphysics of the essences of modes.2 ²I would like to thank John Carriero, Calvin Normore, Eliot Michaelson, Eileen Nutting, Paul Nichols, Alexi Patsaouras, Rachel Johnson and Sarah Jansen for reading and commenting on earlier versions of this paper. I situate Spinoza's use of the notion of essence as a response to traditional, Aristotelian, ways of thinking about essence. I argue that, although Spinoza rejects part of the Aristotelian conception of essence, according to which it is in virtue of its essence that a thing is a member of a kind, he nevertheless retains a different part of such a conception, according to which an essence is some structural feature of a thing which causally explains other, non-essential features. I go on to develop an account of Spinoza's metaphysics of essence, according to which essences, what he sometimes calls formal essences, are produced by the divine essence prior to and independent of the creation of finite modes, and according to which essences are the formal or exemplar causes of finite modes. I then argue that finite modes, in virtue of the formal essences which they actualize, are genuine causal relata. Finally, I offer some speculations about Spinoza's answer to the question, ‘Why, in a necessitarian cosmos filled with formal essences, should there be temporal finite modes at all?’     

Spinoza on Essences,Universals, and Beings of Reason

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 (‘agreements’) 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.     

When Does Truth Matter? Spinoza on the Relation between Theology and Philosophy

One of the aims of Spinoza's Tractatus Theologico‐Politicus is to vindicate the view that philosophy and theology are separate forms of enquiry, neither of which has any authority over the other. However, many commentators have objected that this aspect of his project fails. Despite his protestations to the contrary, Spinoza implicitly gives epistemological precedence to philosophy. I argue that this objection misunderstands the nature of Spinoza's position and wrongly charges him with inconsistency. To show how he can coherently allow both that theology and philosophy employ independent epistemological standards, and that philosophy is epistemologically superior to theology, we need to step back from the immediate disputes to which the Tractatus is a response and examine a Ciceronian distinction on which Spinoza indirectly draws. As well as enabling us to vindicate Spinoza's position, it places his alleged naturalism in a new light and portrays philosophizing as a form of piety.     

‘Disempowered by Nature’: Spinoza on The Political Capabilities of Women

This paper examines Spinoza's remarks on women in the Political Treatise in the context of his views in the Ethics about human community and similitude. Although these remarks appear to exclude women from democratic participation on the basis of essential incapacities, I aim to show that Spinoza intended these remarks not as true statements, but as prompts for critical consideration of the place of women in the progressive democratic polity. In common with other scholars, I argue that women, in Spinoza's system, are deprived of freedom and political participation not by their essential natures, but by their social and historical circumstances. I differ from other scholars, however, in basing this conclusion on the different critical functions of the Political Treatise and the Ethics. Following that critical comparison, I consider Spinoza's views on the `natural right' of women and their equal capacity for political participation in terms of his arguments for the compositional similarity of men and women. Finally, I argue that Spinoza offers an explanation for women's actual disempowerment through his account of economic dependence within marriage.     

A Tale of Two Thinkers,One Meeting,and Three Degrees of Infinity: Leibniz and Spinoza (1675–8)

The article presents Leibniz's preoccupation (in 1675–6) with the difference between the notion of infinite number, which he regards as impossible, and that of the infinite being, which he regards as possible. I call this issue ‘Leibniz's Problem’ and examine Spinoza's solution to a similar problem that arises in the context of his philosophy. ‘Spinoza's solution’ is expounded in his letter on the infinite (Ep.12), which Leibniz read and annotated in April 1676. The gist of Spinoza's solution is to distinguish between three kinds of infinity and, in particular, between one that applies to substance, and one that applies to numbers, seen as auxiliaries of the imagination. The rest of the paper examines the extent to which Spinoza's solution solves Leibniz's problem. The main thesis I advance is that, when Spinoza and Leibniz say that the divine substance is infinite, in most contexts it is to be understood in non-numerical and non-quantitative terms. Instead, for Spinoza and Leibniz, a substance is said to be infinite in a qualitative sense stressing that it is complete, perfect and indivisible. I argue that this approach solves one strand of Leibniz's problem and leaves another unsolved.     

On religious and cultural objects: Articulate and inarticulate bodies in Spinoza's philosophy of nature

Spinoza's philosophy is often overlooked when it comes to thinking about matters concerning art and culture. While recent work has done much to address this, his philosophy remains ambiguously related to the theorisation of things such as temples, poems, and paintings. This article argues that it is by turning to Spinoza's theorisation of the sacred in the Theological‐Political Treatise, that we can best derive his philosophical position on culture and its objects. I argue that Spinoza locates the sanctity of a religious object–what he calls its “articulateness”–in its particular use‐relation with a people. In a similar manner, Spinoza locates the “meaning” and articulateness of words in the use that people make of them, thereby secularising the sanctification process for cultural objects. I argue that this relation of “use” between cultural‐religious objects and human beings and their societies is the way in which we can best discern Spinoza's philosophical position regarding art and culture, as well as further develop his potential contribution to cultural and art theory.
