This paper argues that Spinoza held substances other than God to be inconceivable. It uses this claim to develop a novel response to the Problem of Other Substances, the problem of explaining why some of Spinoza’s proofs for God’s existence cannot be used to prove the existence of a non-divine substance instead.

Are there moral constraints on the pursuit of the good? Our intuitions suggest that we may not use another person as a means to achieve a good outcome, even if that good outcome reduces the amount of using-as-a-means that occurs overall. These intuitions are assumed to be incompatible with consequentialism and to show the need for a deontological constraint on using others as a means. This assumption is a mistake. In this paper, I show that consequentialists can justify the same (...) case-based intuitions that are thought to support a moral constraint on using others as a means. (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.

Spinoza rarely refers to art. However, there are extensive resources for a Spinozist aesthetics in his discussion of health in the Ethics and of social affects in his political works. There have been recently been a few essays linking Spinoza and art, but this essay additionally fuses Spinoza’s politics to an affective aesthetics. Spinoza’s statements that art makes us healthier (Ethics 4p54Sch; Emendation section 17) form the foundation of an aesthetics. In Spinoza’s definition, “health” is caused by external objects that (...) maintain our power to act in a variety of ways. Humans need such objects because our complex bodies constantly lose or consume many parts necessary to our overall functioning. Notably, Spinoza defines humans’ bodies through this complexity (2p13Sch), so health as maintenance of complexity is a distinctly human endeavor. Further, while art is not the only healthy activity, I argue that art is a particularly potent cure, which explains Spinoza’s otherwise opaque comment that music can cure melancholy (by which he meant a near-total inability to act, akin to death). Rather than only causing frivolous pleasures, art may be as essential to human flourishing as are other human beings in general; other people are “most useful” because of the variety of actions they make possible (4p35Cor & Sch1). Art’s production of a dizzying variety of affects is likewise most useful for health. -/- Having established how art in general affects the individual, I then explain the role of artists in shaping social groups. Artists use vivid and highly charged affective techniques, as do political sovereigns and religious prophets (TTP chapters 1-2 & 15-16). However, sovereigns and prophets are concerned exclusively with “morality,” defined by Spinoza as the use of affects (primarily based on fear and hope) to produce “obedience” in the generic multitude or people at large. An artist, however, rarely causes affects in the whole nation, affecting instead only a smaller niche or “sub-genre” of people. The affects produced in this group are also not identical to those used by sovereigns, since artists do not primarily deploy sad affects of hope and fear but instead use a wide variety of joyful affects. Further, in Spinoza’s analysis of ceremonies (TTP chapter 5), we see how small groups exposed to repeated ceremonies or social practices eventually develop new strengths which they lacked before. Repeated exposure to shared aesthetic “ceremonies” (e.g., live music performances) of the same sub-genre will over time create the capacity of new powers in the sub-genre of people, which distinguishes them from the masses. Spinoza says sovereigns forge a “second nature” for the generic people through affects; we can then affirm that smaller groups exposed to a distinct sub-genre of art can acquire a new “third nature” which will contain unique powers extending beyond healthy maintenance of their existing bodies. That is, art in general is necessary to flourish and remain whole (maintaining health), but it can also occasionally expand what one is to unforeseen heights (through specific artistic sub-genres).

Spinoza’s account of reason in the Short Treatise has been largely neglected. That account, I argue, has at least four features which distinguish it from that of the Ethics: in the Short Treatise, (1) reason is more sharply distinguished from the faculty of intuitive knowledge, (2) reason deals with things as though they were ‘outside’ us, (3) reason lacks clarity and distinctness, and (4) reason has no power over many types of passions. I argue that these differences have a unified (...) explanation, consisting of a principle that Spinoza accepts in both works and a central change in his views. The principle is that whatever we find in ourselves has more power over us than anything which comes from outside, and the change is in making the objects of reason common things or common notions. Understanding this, I claim, sheds important light on the psychological and epistemological motivations behind Spinoza's mature doctrines. (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.

El sistema filosófico de Spinoza no puede ser considerado en rigor como panteísta, sino panenteísta. Este artículo intenta reforzar esta tesis analizando los conceptos de Natura naturans y Natura naturata, a veces confundidos en la obra de Spinoza. Se establece además una comparación de ambos conceptos en Spinoza y en David Nieto, autor de una obra titulada De la divina providencia, o sea naturaleza universal o natura naturante, al tiempo que se señalan las diferencias entre las concepciones inmanentes de la (...) divinidad de ambos autores.

ABSTRACT: I argue that when Spinoza describes substance and its attributes as he means that they are utterly indeterminate. That is, his conception of infinitude is not a mathematical one. For Spinoza, anything truly infinite eludes counting s conception is closer to a grammatical one. I conclude by considering a number of arguments against this account of the Spinozan infinite as indeterminate.

Russell’s critique of substance monism is an ideal starting point from which to understand some main concepts in Spinoza’s difficult metaphysics. This paper provides an in-depth examination of Spinoza’s proof that only one substance exists. On this basis, it rejects Russell’s interpretation of Spinoza’s theory of reality as founded upon the logical doctrine that all propositions consist of a predicate and a subject. An alternative interpretation is offered: Spinoza’s substance is not a bearer of properties, as Russell implied, but an (...) eternally active, self-actualizing creative power. Eventually, Spinoza the Monist and Russell the Pluralist are at one in holding that process and activity rather than enduring things are the most fundamental realities. (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.

This paper examines some aspects of Spinoza's metaphysics of the essences of modes.2 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?". (shrink)

(2013). Spinoza and the Cosmological Argument According to Letter 12. British Journal for the History of Philosophy: Vol. 21, No. 1, pp. 57-77. doi: 10.1080/09608788.2012.696052.

One of the most famous and identifiable of Spinoza’s ideas is his amor Dei intellectualis (the intellectual love of God). It has been argued that this concept is somewhat alien to the main tenets of the Ethics, especially since it is reminiscent of more orthodox religious relations to God, and has a certain mystical (and so, nonrational) quality. In this paper, I will show that it is a consistent development of Spinoza’s interconnected and elaborate theories of knowledge and the affects. (...) Spinoza discusses three kinds of love: passionate love, friendship and the intellectual love of God. The intellectual love of God is nothing but a necessary outcome of Spinoza’s rationalistic project as a whole. Moreover, by culminating his ethical theory with such a concept, Spinoza is placing himself in a rich tradition of thinkers who develop epistemological and ethical systems that put love (either as eros or philia) as the backbone of their philosophy. In order to illustrate the similarities between Spinoza’s philosophical use of love and that of his predecessors, I will address salient features of Plato’s and Aristotle’s thought, emphasizing the relationship between love and ethics, as well as the nature of the philosophical impulse.

Before presenting his own account of value in the Ethics, Spinoza spends much of EIAppendix and EIVPreface attempting to refute a series of axiological ‘prejudices’ that he takes to have taken root in the minds of his readership. In doing so, Spinoza adopts what might be termed a ‘genealogical’ argumentative strategy. That is, he tries to establish the falsity of imagined readership’s prejudices about good and bad, perfection and imperfection, by first showing that the ideas from which they have arisen (...) are themselves false. Many elements of this genealogy, however, remain unclear. First, both the nature of the metaethical prejudices Spinoza believes we have been labouring under, and the metaphysical prejudices that he takes to have given rise to them, continue to attract widespread disagreement. Although much less commented on, it is also not entirely obvious why Spinoza takes the one to have engendered the other. In this article, I attempt to clarify Spinoza’s reasoning in both of these respects, ultimately concluding that Spinoza offers us two accounts of how this process has occurred, the first beginning from an anthropocentric doctrine of divine providence, the second from more secular, perhaps more purely Aristotelian metaphysical tradition.

I address an apparent conflict between Spinoza’s concepts of immanent causation and acting/doing [agere]. Spinoza apparently holds that an immanent cause undergoes [patitur] whatever it does. Yet according to his stated definition of acting and undergoing in the Ethics, this is impossible; to act is to be an adequate cause, while to undergo is to be merely a partial cause. Spinoza also seems committed to God’s being the adequate cause of all things, and, in a well-known passage, appears to deny (...) categorically that God is capable of undergoing. How then can God also be the immanent cause of all things, as Spinoza claims? On the basis of a close reading of the passage in question, I argue that Spinoza actually distinguishes between two senses of undergoing. An immanent cause undergoes not by being a partial cause but rather by being the metaphysical subject of its effect. While this sense of undergoing has its roots in scholasticism, Spinoza’s willingness to attribute such a capacity to undergo to God is idiosyncratic and reveals important ways in which his understanding of essence, perfection, and causation differs from the scholastic model.

A tese de que o conceito espinosista de ideia de afecção, introduzido na Ética, expressa o sentido mais preciso do que seja, para o autor, o conceito de ideia da imaginação. Este texto pretende problematizar essa leitura, procurando fornecer subsídios para a hipótese de que ela não é nem inequivocamente corroborada pelo texto da Ética, nem exigida pela doutrina aí apresentada. -/- It is widely accepted by scholars that Spinoza’s concept of idea of affection, introduced in the Ethics, states his (...) notion of the idea of imagination. In this paper I address this reading, claiming that it is not either unequivocally corroborated by the text of the Ethics, or required by the doctrine developed there. (shrink)

What surfaces first when one examines the philosophy of mind of Sartre and Spinoza are the differences between them. For Spinoza a human mind is a mode of the divine mind. That view is a far cry from Sartre’s view of human consciousness as a desire never achieved: the desire to be god, to be the foundation of one’s own existence. How could two philosophers, one a determinist and the other who grounds human freedom in the nature of consciousness itself, (...) be seen as having any commonalities worth exploring? How could the noted user of the deductive method and one of the most important phenomenologists of the twentieth century share any philosophical ground at all? I will argue in this paper that despite the very real differences between their two philosophies, there are striking similarities between Sartre’s view of consciousness and Spinoza’s view of the mind. They become apparent when one examines each one’s analysis of the nature of mind and its relationship to itself, the body, and the world. Both are heir to a kind of Aristotelian naturalism. This commonality between them derives from their mutual rejection of Descartes’ substance dualism. I first explore the consequences of that rejection on how each one conceives of the relationship between the mind and its objects. Next I examine their view of the mind’s relation to itself and finally I look at how each one understood the mind’s relationship to the body and the world. The examination of their two views reveals how much they anticipate and support theories of mind defended by contemporary analytic philosophers of mind. (shrink)

El derecho natural spinozista es el concepto central que articula este estudio. Y en relación con el derecho natural trataremos de explicar otros conceptos fundamentales de la filosofía de Spinoza: el común decreto, las supremas potestades y la salvación del pueblo o concordia. Los elementos a analizar son, pues, la materia, la forma, los agentes y los fines. El autor de este artículo parte de un presupuesto simple: el derecho natural representa el aspecto material del pensamiento de Spinoza. Ahora bien, (...) así como el derecho natural nos debe dar razón de la materialidad en la filosofía de Spinoza, lo que él llama el común decreto nos puede ayudar a describir el aspecto formal. Por otro lado, lo que Spinoza denomina las supremas potestades nos pueden servir para descubrir el plano de los agentes. Y, por último, la salvación del pueblo puede ser la referencia oportuna a la hora de ordenar el plano de los fines en la filosofía de Spinoza. (shrink)

The sheer complexity of Spinoza's thinking makes it impossible for any movement to use him as a patron. But philosophically engaged ecologists and environmentalists may find in his system an inexhaustible source of inspiration. This holds good even if he was personally a ?speciesist? and uninterested in animals or landscapes. Underestimation of his potential help is due to a variety of factors: failure to pay enough attention to the structure of his system, belief in its close resemblance to that of (...) Hobbes, and interpretation of ?understanding love of God? as a contemplative, general attitude incompatible with environmentalist activism and interest in every living being. The system of Spinoza is compatible with activism ? like that of Jan de Witt ? and with respect for all things as ?expressions of the power of God or Nature? (shrink)

This study argues that the exploration of Hegel and Spinoza’s philosophies of material Nature yields a more compelling critique of Spinoza’s thought than either Hegel himself or commentators have recognised. Rather than attempting a full comparison of Hegel and Spinoza’s accounts of material Nature, this study focuses on elaborating a critique of the deficiencies found, from a Hegelian standpoint, in Spinoza’s account of extended Nature. This study argues that the Hegelian critique of Spinoza’s theory of extended Nature takes at least (...) two major interrelated forms. Firstly, this critique suggests that Spinoza does not adequately derive the necessity of Substance’s existence as Extension, as motion and rest, and as finite bodies. This is demonstrated in this study through an account of Hegel’s immanent development of Nature as such and its mechanical forms from the conclusion of the Science of Logic. Secondly, this critique suggests that Spinoza’s mechanical and quantitative conception of the broader picture of material Nature is inadequate. This is demonstrated through an account of Hegel’s critique of any purely mechanical conception of the natural world, arguing instead that Nature is necessarily driven through a series of qualitatively different stages including the chemical and organic. This study makes an original scholarly contribution through its investigation of the Hegel-Spinoza relationship in the specific context of their philosophies of material Nature, an aspect of this relationship previously unexplored. This study thereby makes the first step in the expansion of the scholarship of the Hegel-Spinoza relationship into this new area, opening a promising new avenue for future work on these great philosophers.

I use Jonathan Bennett’s, Gilles Deleuze’s and Pierre Macherey’s interpretations of Spinoza to extract a theory of time and duration from Spinoza. I argue that although time can be considered a product of the imagination, duration is a real property of existing things and corresponds to their essence, taking essence (as Deleuze does) as a degree of power of existing. The article then explores the relations among time, duration, essence and eternity, arguing against the idea that Spinoza’s essences or Spinoza’s (...) eternity are atemporal. Essences and eternity both involve necessary references to time, but the time involved is not that of the “fortuitous sequence of events” apprehended through sensory experience. Rather, the “time” is that implicit in the necessity of God’s self-determination through God’s differentiation into natura naturans and natura naturata, which is involved in the production and differentiation of eternal essences.

This paper explores the nature and working of Spinoza’s philosophical religion. In doing so, it critically engages with Carlos Fraenkel’s study of the tradition of philosophical religions and Spinoza’s place in it. Spinoza can be said to be part of this tradition because the relation of his philosophical conception of God to the conceptions of God of some popular religions (especially Christianity) can be construed as that of the universal versus the particular, in which the particular expresses something of the (...) universal, in an inadequate yet more readily accessible way. The account of Spinoza’s philosophical religion provided is kindred to Fraenkel’s, but it also explicitly discusses a crucial issue which Fraenkel only sparingly addresses, viz. the question how we must envisage the transition from a confused, imaginary to a more rational conception of God. A related issue the paper addresses concerns the question whether – and, if so, how – the dogmas of the universal faith can be reinterpreted philosophically. These discussions underpin a critical assessment of Fraenkel’s claim that Spinoza’s philosophical religion project is, ultimately, flawed. (shrink)
