The two manuscripts of the Korte Verhanedling that were discovered in the mid-nineteenth century contain two appendices. These appendices are even more enigmatic than the KV itself, and it is the first appendix that is the subject of this study. Unfortunately, there are very few studies of this text, and its precise nature seems to be still in question after more than a century and a half of scholarship. It is commonly assumed that the appendices were written after the body (...) of the KV and I am not going to challenge this assumption. The first appendix is written in a geometric manner, and it contains seven axioms and four propositions. Strikingly, it does not include any definitions. This is in sharp contrast with Spinoza's Ethics and his 1663 book on Descartes' Principles of Philosophy, which are similarly written in a geometric manner but include both definitions and axioms. One could perhaps suspect that the text we currently have is merely a fragment from a more extensive work which included definitions. In my paper, I will show that this is not the case, and that the first appendix belongs to a genuine work of Spinoza that never contained definitions. I would further argue that the first appendix is most probably the earliest draft we currently have of Spinoza's magnum opus, the Ethics, but we have a long way to go before we reach that conclusion.

Generosity is not best understood as an alliance of forces, necessary for mortal beings with limited time and skills. Sociability as generosity exceeds the realm of need and follows directly from our strength of character [fortitudo] because it expresses a positive power to overcome anti-social passions, such as hatred, envy, and the desire for revenge. Spinoza asserts that generous souls resist and overwhelm hostile forces and debilitating affects with wisdom, foresight, and love. The sociability yielded by generosity, then, is not (...) just a form of cooperation we need to survive and produce leisure for study and contemplation. Generosity is not a mere means but a positive expression of freedom, because it is the activity through which a strong soul (and body) transforms enemies into friends. It is not an expression of lack, but of an acquired power that infuses one’s social milieu with empowering love and joy, creating agreements in nature and power where they did not previously exist. Attention to generosity reveals not only that there are social virtues proper to Spinoza’s understanding of freedom but that freedom itself is, by necessity, social. (shrink)

Spinoza’s geometrical approach to his masterwork, the Ethics, can be represented by a digraph, a mathematical object whose properties have been extensively studied. The paper describes a project that developed a series of computer programs to analyze the Ethics as a digraph. The paper presents a statistical analysis of the distribution of the elements of the Ethics. It applies a network statistic, betweenness, to analyze the relative importance to Spinoza’s argument of the individual propositions. The paper finds (...) that a small percentage of the propositions greatly exceed the majority in this importance. The paper then describes two logical structures that appear respectively in the Ethics and argues that they result in redundancy in the sense that about ten percent of the propositions could have been eliminated. The appendices list these structures and describes how the resources of the study can be made available to readers. (shrink)

According to Steven Nadler's novel interpretation of Spinoza's much discussed ‘free man’, the free man is not an unattainable ideal. On this reading, the free man represents an ideal condition not because he is passionless, as has often been claimed, but because even though he experiences passions, he ‘never lets those passions determine his actions’. In this paper, I argue that Nadler's interpretation is incorrect in taking the model of the free man to be an attainable ideal within our (...) reach. Furthermore, I show that Spinoza's moral philosophy has room for another ideal yet attainable condition, which is represented by the wise man. On my reading, becoming a wise man consists not in surmounting human bondage, but in understanding ourselves as finite expressions of God's power and, thereby, coming to terms with the ineliminability of bondage for us due to our very human or modal condition in the Spinozistic universe.

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)

I argue that Spinoza is more of a moral realist than an anti-realist. More specifically, I argue that Spinoza is more of a realist than Kant, and that his view has deep similarities with Plato's metaethics. Along the way, I identify three approaches to the moral realism/anti-realism distinction. Classifying Spinoza as a moral realist brings out a number of important complexities that have been overlooked by many of Spinoza's readers and by many contemporary metaethicists.

Spinoza's Ethics self-consciously follows the example of Euclid and other geometers in its use of axioms and definitions as the basis for derivations of hundreds of propositions of philosophical si...

In the following article, I aim to elucidate the meaning and scope of Spinoza’s vocabulary related to ‘consciousness’. I argue that Spinoza, at least in his Ethics, uses this notion consistently, although rarely. He introduces it to account for the knowledge we may have of the mind considered alone, as conceptually distinct from the body. This serves two purposes in Spinoza’s Ethics: to explain our illusion of a free will, on the one hand, and to refer to the (...) knowledge we have of our mind as something eternal, on the other. I contend, therefore, that we should not confuse Spinoza’s technical use of the notion of ‘consciousness’ with the ‘degrees of animation’ that he also evokes in the Ethics. Consciousness, for Spinoza, is neither a faculty, nor a property specific to certain minds or ideas. Furthermore, consciousness does not come in degrees. Indeed, Spinoza’s account of consciousness is not intended to differentiate kinds of minds in terms of awareness of their respective ideas. (shrink)

In this paper I argue, based on a comparison of Spinoza's and Descartes‟s discussion of error, that beliefs are affirmations of the content of imagination that is not false in itself, only in relation to the object. This interpretation is an improvement both on the winning ideas reading and on the interpretation reading of beliefs. Contrary to the winning ideas reading it is able to explain belief revision concerning the same representation. Also, it does not need the assumption that (...) I misinterpret my otherwise correct ideas as the interpretation reading would have it. In the first section I will provide a brief overview of the notion of inherence and its role in Spinoza‟s discussion of the status of finite minds. Then by examining the relation between Spinoza‟s and Descartes‟ distinction of representations and attitudes, I show that affirmation can be identified with beliefs in Spinoza. Next, I will take a closer look at the identification of intellect and will and argue that Spinoza's identification of the two is based on the fact that Spinoza sees both as the active aspect of the mind. After that, I analyze Spinoza‟s comments on the different scopes of will and intellect, and argue that beliefs are affirmations of the imaginative content of the idea. Finally, through Spinoza‟s example of the utterance of mathematical error, I present my solution to the problem of inherence of false beliefs. (shrink)

This essay offers an in-depth reading of the geometrical illustration of Ethics IIP8S and shows how it can be used to explicate the whole architecture of Spinoza’s system by specifying the way in which all the key structural features of his basic ontology find their analogies in the example. The illustration can also throw light on Spinoza’s ontology of finite things and inform us about what is at stake when we form universal ideas. In general, my reading of IIP8S (...) thus elucidates what it means, for Spinoza, to think geometrically or to consider geometry as a model: fundamentally, geometricity is not a form of exposition but the way in which reality itself is structured.

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. (shrink)

The claim of this paper is to present Spinoza’s view on self-esteem and positive reciprocity, which replaces the human being in a monistic psycho-dynamical affective framework, instead of a dualistic pedestal above nature. Without naturalising the human being in an eliminative materialistic view as many recent neuro-scientific conceptions of the mind do, Spinoza finds an important entry point in a panpsychist and holistic perspective, presenting the complexity of the human being, which is not reducible to the psycho-physiological conditions of life. (...) From a panpsychist point of view, qualities and values emerge from the world, in a situation similar to what could be seen in animism, or early childhood psychology, where the original distance between the mind and the exterior thing is reduced ad minima, and both can even interrelate in a confusing manner. Human reality is nevertheless a social reality, it supposes a basis for shared competencies, that we will present as grounded on the one hand of the sustaining character of the essence of the animal-man as will-to-power. Negatively speaking we all share same asocial tendencies and affects. This aspect is not only negative but it is also a will to develop and master the environment, because values have an onto-metaphysical immanent dimension in nature, not because there is an individual bottom-up will to survive, but rather a will to live in harmony with the surrounding world. On the other hand, we shall see that Spinoza understood and described perfectly the power of the mind over the power of the affects, as a co-constituting dimension, which is alienating natural dependencies, leaving an inner space for the objectification of ethical values, not related to mere compensation mechanisms.

Spinoza’s account of memory has not received enough attention, even though it is relevant for his theory of consciousness. Recent literature has studied the “pancreas problem.” This paper argues that there is an analogous problem for memories: if memories are in the mind, why is the mind not conscious of them? I argue that Spinoza’s account of memory can be better reconstructed in the context of Descartes’s account to show that Spinoza responded to these views. Descartes accounted for the preservation (...) of memories by holding that they are brain states without corresponding mental states, and that the mind is able to interpret perception either as new experience or as memory. Spinoza has none of these conceptual resources because of his substance monism. Spinoza accounts for memories as the mind’s ability to generate ideas according to the order of images. This ability consists in the connection of ideas, which is not an actual property, but only a dispositional one and thus not conscious. It is, however, grounded in the actual property of parts of the body, of which ideas are conscious. (shrink)

In this paper, through a close reading of Spinoza's use of common notions I argue for the role of experiential and experimental knowledge in Spinoza's epistemology.

In this article I examine how a teleological (or purposive) reading of Spinoza’s conatus shapes the ethical framework of his philosophy. I first introduce Spinoza’s criticism of teleology and argue contra many critics that Spinoza has a mild approach to human teleology. On the basis of this idea, I develop the claim that the human conatus includes purposive elements such that it is envisioned as a purposive being that is oriented towards the adequate knowledge of Nature or God, the conceptions (...) of wisdom, love and joy and the notion of an ideal human nature. From the teleological reading of human conatus, I draw the conclusion that Spinoza’s ethics is inclusive of objective, humanistic, and essentialist elements in the sense that it situates human agents as directed towards ethical ends to be pursued through their conative activity. In this sense, throughout this paper, I take issue with the anti-teleological reading of conatus that is predominantly related to the subjectivistic, anti-humanistic, and non-essentialist interpretation of Spinoza’s ethics. In doing so, I argue that Spinoza’s ethics is not entirely free from objective, humanistic and essentialist elements, by putting a particular emphasis on the distinguishing character of the purposive essence of his human conatus.

François Lamy, a Benedictine monk and Cartesian philosopher whose extensive relations with Arnauld, Bossuet, Fénélon, and Malebranche put him into contact with the intellectual elite of late-seventeenth-century France, authored the very first detailed and explicit refutation of Spinoza’s Ethics in French, Le nouvel athéisme renversé. Regrettably overlooked in the secondary literature on Spinoza, Lamy is an interesting figure in his own right, and his anti-Spinozist work sheds important light on Cartesian assumptions that inform the earliest phase of Spinoza’s critical (...) reception in the seventeenth-century. I begin by presenting Lamy’s life and the contentious state of Spinoza’s French reception in the 1680 and 1690s. I then discuss a central argument in Lamy’s refutation, namely the Cartesian objection that Spinoza’s account of the conceptual independence of attributes is incompatible with the theory of substance monism. Contrasting Lamy’s objection with questions put to Spinoza by de Vries and Tschirnhaus, I maintain that by exhibiting the direction Spinoza’s views on substance and attribute took in maturing we may accurately assess the strength of Spinoza’s position vis-à-vis his Cartesian objector, and I argue that, in fact, Spinoza’s mature account of God as an expressive ens realissimum is not vulnerable to Lamy’s criticism. In conclusion, I turn to Lamy’s objection that Spinoza’s philosophy is question-begging in view of Spinoza’s account of God, and I exhibit what this point of criticism tells us about the intentions of the first French Cartesian rebuttal of the Ethics.

In IVP50S, Spinoza claims that “one who is moved to aid others neither by reason nor by pity is rightly called inhuman. For (by IIIP27) he seems to be unlike a man” (IVP50S). At first blush, the claim seems implausible, as it relies on the dubious assumption that beings will necessarily imitate the affects of conspecifics. In the first two sections of this paper, I explain why Spinoza accepts this thesis and show how this claim can be made compatible with (...) his account of representation. In the third and final section I offer an auxiliary defense of the thesis, showing that, according to Spinoza, to be human is to sociable, and sociability depends on the imitation of the affects.

As in classical Latin philosophical and theological texts, Spinoza did not make any semantic distinction between the concepts of conscientia and conscius, and used one interchangeably. But the concept of conscientia is used as an “inner voice” or “conscience” meaning “moral sensitivity” or “moral awareness” and expresses both rational and irrational processes in traditioanl philosophy. On the other hand, the concept of conscius is used in the sense of “consciousness” and expresses a mental or psychological reflexive activity based on rational (...) processes in the same tradition. Based on Spinoza's use of the two concepts in the same sense, this study claims that “moral sensitivity” is formed as a result of reflexive thinking, which is a mental action. Where consciousness is understood as a reflexive activity based on the relationship between ideas, it is argued that “moral awareness” occurs in the mind as an idea formed as a result of the relationship between ideas. In the study, it is determined that Spinoza developed a kind of “moral consciousness” theory based on the awareness in question, rather than a “conscience theory”. The main focus of the study is that the idea of “good” and “evil”, which are the basic concepts in Spinoza’s ethics, arise from the idea of “joy” and “sadness” that occur as emotions in the mind. Here, “joy” or “sadness” is considered as the primary ideas that occur in the mind as a result of the affection of the body, and “good” or “bad” as secondary ideas formed by the mind as a result of contemplation on these primary ideas. In the article, the theory of “moral consciousness” is based on the “ideas of ideas”, which are the secondary ideas in question. Keywords: Consciousness, Conscience, Awareness, Moral Consciousness, Good-Evil, Joy-Sadness. (shrink)

The impermanence of human affairs is a major theme in Spinoza’s discussions of political histories, and from our present-day perspective it is both intriguing and ironic to see how this very theme has played out in the evolving fate of Spinoza’s association with atheism. While Spinoza’s contemporaries charged him with atheism in order to impugn his philosophy (and sometimes his character), in our times many lay readers and some scholars portray Spinoza as an atheist in order to commemorate his role (...) as a founder of modern secularism. In this paper, I will argue that Spinoza deserves neither vilification nor praise for being an atheist, for the simple reason that he was not one (unless one employs the term ‘atheism’ in a very peculiar sense). I have chosen the current topic as my contribution to a volume focused on the TTP, the Ethics, and their interrelations because it is precisely these two books which brought about the common reactionary accusation of atheism by Spinoza’s contemporaries. Addressing Spinoza’s 1663 book, Descartes’ Principles of Philosophy, Bayle writes: “Spinoza appears as orthodox in that book about the nature of God.” As we shall shortly see, Descartes too was accused of atheism by some of his contemporaries (though not so by Bayle). The latter designates his target quite explicitly: “[Spinoza’s] Tractatus Theologico Politicus, printed in Amsterdam, in the year 1670, is a pernicious and execrable book which contains all the seeds of the Atheism he plainly discovered in his Opera Posthuma.” François Lamy, in his 1696 Le nouvel athéisme renversé, also focused on the Ethics and the TTP in his attack on Spinoza’s atheism. Bayle’s reference to the Opera Posthuma is ostensibly targeting the Ethics at least primarily, if not uniquely. Even the most suspicious and distrustful mind would have to labor hard in order to find atheism in the Hebrew Grammar, or even in the Tractatus Politicus where Spinoza argues that it is not within the power, and hence right, of the commonwealth to induce people to adopt utterly absurd beliefs, such as “that the whole is greater than its part or that God does not exist.” The TTP and the Ethics are the works where Spinoza launches his merciless attack on anthropocentric thinking and anthropomorphic religion. Spinoza’s panentheism (“quicquid est, in Deo est”) constitutes the metaphysical foundation of the Ethics, and it is repeatedly and clearly alluded to in the TTP. Since it is these two elements – (1) Spinoza’s open assertions of panentheism and (2) his critique of andromorphic conceptions of God – which are the historical grounds for the atheism charge, it seems natural that the merit of this charge should be decided primarily by examination of these two foundational works. I will proceed in the following manner. In the first part of the paper, we will make our first acquaintance with the imputation of atheism by Spinoza’s contemporaries and Spinoza’s response to the charge (or lack thereof). In the second part, I discuss three broad strategies, or hermeneutic avenues, that have been pursued to impute atheism to Spinoza. The first of the three was dominant in Spinoza’s time, while the latter two were employed more recently. These strategies are not mutually exclusive and we can find occasionally various combinations of different shades of these three strategies. In this part, I will also raise some preliminary questions about the cogency of the hermeneutics employed by each strategy. In the third and fourth parts of the paper, I will discuss a small selection of key texts from the Ethics and the TTP, respectively, and argue that the atheist readings fail to make sense of these key passages (unless one adopts an extreme hermeneutics of suspicion which could allegedly find any view harbored in any text). Let me stress that this selection of passages is far from comprehensive, and that dozens of other passages can be adduced to establish the very same point. I hope by the end of the fourth part to convince the reader of the deep problems besetting the atheist readings. In the fifth and last part, I show that both panentheism and the critique of anthropomorphic religion and anthropomorphic conceptions of providence were quite common within rabbinic discourse. Thus, I will argue that if we are not in the business of announcing that both Maimonides and the Kabbalists were atheists, we should avoid the same imputation to Spinoza. Underlying my argument in this final part is the claim that at least some perceptions of Spinoza as an atheist are instances of what could be termed conceptual colonialism, i.e. the enforcement of the categories of a hegemonic culture (in this case, Western Christianity ) on minority cultures (in the current case, rabbinic Judaism). To be clear, this attitude need not be motivated by ill intentions or racism. It is always tempting and easy to explain the unfamiliar through the familiar, but conceptual stagnation and insistence on imposing the categories of the familiar on other cultures may quickly lead to deep distortion and blindness, despite one’s best intentions. Unless one is exceedingly careful to avoid the – completely natural – temptation to impose one’s own categories on a foreign culture (and to look for the coin only under the street light), one is likely to end up with distorted conceptions of the relevant alien culture, despite one’s best intentions.

Spinoza's political thought has been subject to a significant revival of interest in recent years. As a response to difficult times, students and scholars have returned to this founding figure of modern philosophy as a means to help reinterpret and rethink the political present. Spinoza's Authority Volume I: Resistance and Power in Ethics makes a significant contribution to this ongoing reception and utilization of Spinoza's political thought by focusing on his Ethics. By taking the concept (...) of authority as an original framework, this books asks: How is authority related to ethics, ontology, and epistemology? What are the social, historical and representational processes that produce authority and resistance? And what are the conditions of effective resistance? -/- Spinoza's Authority features a roster of internationally established theorists of Spinoza's work, and covers key elements of Spinoza's political philosophy, including: questions of authority, the resistance to authority, sovereign power, democratic control, and the role of Spinoza's "multitudes".

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

Although numerous commentators have attempted to decipher Spinoza's intended meaning within the "Ethics Part 1- Concerning God",it does not appear as if anyone has effectively identified 'Concerning God' as the controlling idea which holds the key to the absolutely unique contribution which Baruch has bequeathed to human knowledge within the unity of thought achieved in the "Ethics". Part 1 is the linchpin for Baruch's entire philosophy. As we approach the 340th anniversary of his passing in February of (...) 1677, and with the passage of time and the shedding of some antiquated superstitious beliefs about god we have gained the distance required to build a new perspective. Many of us feel very strongly that something compelling about the nature of God remains after the anthropomorphic aspects have been dispelled. Thanks to Spinoza's insight into the true nature of the divinity,a next step in human evolution can occur. We will embark on the road to internalizing the divinity. Yes, god is real, ever present and vital in our lives. The goal of this Pamphlet will be to open up the inner workings of Part 1 in the hope that this will incept a new discussion among those interested in Baruch's masterwork. Please join us and find your voice to assist in the unraveling. (shrink)

In this paper I examine the question whether Spinoza can account for the necessity of death. I argue that he cannot because within his ethical intellectualist system the subject cannot understand the cause of her death, since by understanding it renders it harmless. Then, I argue that Spinoza could not solve this difficulties because of deeper commitments of his system. At the end I draw a historical parallel to the problem from medieval philosophy.

Richard Baxter, one of the most famous Puritans of the seventeenth century, is generally known as a writer of practical and devotional literature. But he also excelled in knowledge of medieval and early modern scholastic theology, and was conversant with a wide variety of seventeenth-century philosophies. Baxter was among the early English polemicists to write against the mechanical philosophy of René Descartes and Pierre Gassendi in the years immediately following the establishment of the Royal Society. At the same time, he (...) was friends with Robert Boyle and Matthew Hale, corresponded with Joseph Glanvill, and engaged in philosophical controversy with Henry More. In this book, David Sytsma presents a chronological and thematic account of Baxter's relation to the people and concepts involved in the rise of mechanical philosophy in late-seventeenth-century England. -/- Drawing on largely unexamined works, including Baxter's Methodus Theologiae Christianae (1681) and manuscript treatises and correspondence, Sytsma discusses Baxter's response to mechanical philosophers on the nature of substance, laws of motion, the soul, and ethics. Analysis of these topics is framed by a consideration of the growth of Christian Epicureanism in England, Baxter's overall approach to reason and philosophy, and his attempt to understand creation as an analogical reflection of God's power, wisdom, and goodness, understood as vestigia Trinitatis. Baxter's views on reason, analogical knowledge of God, and vestigia Trinitatis draw on medieval precedents and directly inform a largely hostile, though partially accommodating, response to mechanical philosophy.

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.

(Selection) Despite its contemplative, earnest, and, at times, disarmingly conversational tone, Spinoza's Religion is a rather provocative book. The epithets thrown at Spinoza throughout the early modern period—referring to the Theological-Political Treatise as that most "pestilential book," "forged in hell" by a godless rebel and atheist—are today badges of pride. Spinoza is celebrated among scholars and in popular culture for his uncompromising iconoclasm. He is admired for his refusal, following his ban from Judaism as a young man, to align (...) with any religious faith. Regarded as a staunch critic of religion, Spinoza is credited with paving the way for secular morality, guided by scientific and rational knowledge. With Spinoza's Religion, Carlisle urges us to understand the Ethics as a fundamentally religious text, which, at the same time, transforms our ideas of what religion is. (shrink)

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.

Spinoza's insistence that a deductive metaphysics built from a single Principle or 'Deus sive Natura' and from there proceeding to deduce in descending order all of the 'common properties' or 'Infinite Modalities', is far superior to the inductive method which begins with observation and measurement of particulars and then proceeds to the general. In fact Spinoza recognized in a universe of an infinite number of particulars no metaphysical assertions could be conjectured with any certainty from any investigation of the (...) 'modes' or what is commonly referred to as the world of the 'sensible'.. This is because 'causality' is not a function of any particular object within the finite modes. In other words, any 'thing' which is not the cause of itself cannot render any measurable 'certainty' or 'truth value'. In this Pamphlet we examine Substantia sive Deus sive Natura by moving inclusively from Proposition to Proposition with explanations and interpolated commentary which provide the linkages which make clear the Essence and Nature of true Divinity. -/- Spinoza's insight affords us a completely new and 'contemporary' understanding of what it means to truly grasp 'God'.

In this essay, I evaluate four central metaethical readings of Spinoza’s moral philosophy in the literature: unqualified anti-realism, qualified anti-realism, qualified realism, and unqualified realism. More specifically, I discuss the metaethical readings of Charles Jarrett (unqualified anti-realism), Matthew Kisner (qualified anti-realism), Jon Miller (qualified realism), and Andrew Youpa (unqualified realism), each of which captures core aspects of this debate. My conclusions are that (1) Spinoza is neither an unqualified anti-realist nor an unqualified realist and (2) Spinoza’s ethical framework represents a (...) qualified synthesis of realist (naturalistic) and anti-realist (affective) features.

In this paper I defend an eudaimonistic reading of Spinoza’s ethical philosophy. Eudaimonism refers to the mainstream ethical tradition of the ancient Greeks, which considers happiness a naturalistic, stable, and exclusively intrinsic good. Within this tradition, we can also draw a distinction between weak eudaimonists and strong eudaimonists. Weak eudaimonists do not ground their ethical conceptions of happiness in complete theories of metaphysics, epistemology, or psychology. Strong eudaimonists, conversely, build their conceptions of happiness around an overall philosophical system that extends (...) far beyond ethics, while nevertheless being directed at the promotion of a happy life. I will show that Spinozistic happiness is not only naturalistic, stable, and exclusively intrinsically good, but that Spinoza is also a strong eudaimonist because his ethical account of happiness is incomprehensible without appeal to metaphysical, epistemological, and psychological doctrines. As well, I will explain how the apparent subjective and relativistic features of Spinoza’s ethics do not undermine the eudaimonistic reading, because both Spinoza and the ancient eudaimonists grant that the beliefs/feelings of the subject play a necessary (but insufficient) role in happiness as the highest good.

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

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.

The tenth proposition of Spinoza’s Ethics reads: ‘Each attribute of substance must be conceived through itself.’ Developing and defending the argument for this single proposition, it turns out, is vital to Spinoza’s philosophical project. Indeed, it’s virtually impossible to overstate its importance. Spinoza and his interpreters have used EIp10 to prove central claims in his metaphysics and philosophy of mind (i.e., substance monism, mind-body parallelism, mind-body identity, and finite subject individuation). It’s crucial for making sense of his epistemology (i.e., (...) Spinoza’s account of knowledge and response to skepticism) and in resolving puzzles within the Ethics (i.e., explaining human ignorance of all but two attributes). Even those who do not attribute some of the above claims to Spinoza need EIp10 to defend much of what they believe about Spinoza’s system. This paper locates a previously unnoticed argument for this proposition in Spinoza’s Short Treatise on God, Man, and His Well Being. There, Spinoza shows himself concerned with a powerful and underappreciated form of philosophical skepticism, one with surprising echoes in the work of his contemporary Leibniz as well as in the later Wittgenstein. Spinoza’s introduction of E1p10 in the Ethics circumvents this form of skepticism, solving the problem the Short Treatise envisions while also explaining that text’s argument’s absence from the explicit justificatory structure of the Ethics.

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.

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

The monograph offers an original account of Spinoza’s philosophy and ethics concentrated on its concordance with selected modern neuroscientific theories. The book proceeds through the whole of Spinoza’s philosophy and by increasingly complex analytical account acquaints with its essential frameworks, terminology, and concepts, and is thus accessible also to readers who are not yet familiar with the thought of this peculiar thinker. The fundamental motives of this interpretation are the nature of the mind and the questions of human freedom (...) and human bondage, mainly in connection with the investigation of affects (passions and drives) that the mind tends to be bound with. In his philosophy, Spinoza not only offers brilliant analyses of human experience but in anticipation of modern psychotherapeutic techniques suggests practical methods for the realization of sufficiently functional affective-cognitive self-therapy aimed at the regulation and control of one’s passivity. The understanding of and working with one’s weaknesses is, according to Spinoza, the necessary condition for realizing one’s freedom, or – for being able to shift from pathetics to ethics. (shrink)

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

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.

Spinoza's Political Treatise constitutes the very last stage in the development of his thought, as he left the manuscript incomplete at the time of his death in 1677. On several crucial issues - for example, the new conception of the 'free multitude' - the work goes well beyond his Theological Political Treatise, and arguably presents ideas that were not fully developed even in his Ethics. This volume of newly commissioned essays on the Political Treatise is the first collection (...) in English to be dedicated specifically to the work, ranging over topics including political explanation, national religion, the civil state, vengeance, aristocratic government, and political luck. It will be a major resource for scholars who are interested in this important but still neglected work, and in Spinoza's political philosophy more generally. (shrink)

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

In this essay, I present the basics of Spinoza’s ontology and attempt to go some distance toward clarifying its most pertinent problems. I start by considering the relationship between the concepts of substance and mode; my aim is to show that despite his somewhat peculiar vocabulary there is much here that we should find rather familiar and intelligible, as Spinoza’s understanding of these matters harks back to the traditional distinction of substance and accident, or thing and property. After this I (...) move on to fitting the concept of attribute into Spinoza’s conceptual architecture, and then examine the implications concerning real existents and causation that Spinoza sees these fundamental conceptual commitments as having. The most startling of these implications is of course his monism, according to which there is only one substance. Through this examination it becomes clear that it is only when Spinoza makes the transition from considerations concerning concepts to existential claims that the collision with what was previously commonly accepted becomes inevitable.

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

Classical Greek philosophy in its struggle to grasp the material world from its very beginning has been marked by the – sometimes undercurrent, some others overt and even intense, but never idle – juxtaposition between the mind and the senses, logos and perception or, if the anachronism is allowed, between realism and idealism. Parmenides is reportedly the first philosopher to insistently assert that thought and being are the same by his famous aphorism τὸ γὰρ αὐτὸ νοεῖν ἐστί τε καὶ εἶναι, (...) and that the “way of truth”, as opposed to the “way of opinion”, only runs through the intellect, since the truth is unattainable by the illusory senses. Thus, true may be only what our intellect can firmly grasp, and – by an easy, though not equally sound step – vice versa: that which our intellect can firmly grasp is necessarily true. In this paper I intend to set off Parmenides’ apparent influence on Anselm with regard to the latter’s celebrated ontological argument concerning the existence of God, and the influence of both on Spinoza’s Ethica, which is founded on the key tenet that not only does God necessarily exist – since God is intellectually conceivable –, but that God also by necessity is an utterly good one.

In addition to the notion of power (potentia), Spinoza employs the notion of power of acting (agendi potentia), especially in the Ethics. This raises the question, if Spinoza uses both ‘power’ and ‘power of acting’, what is the difference between the two? What else could power be, for Spinoza, but power of acting? What is the relationship between power and activity in his system? This essays aims at giving answers to these questions; thereby emerges what may be called an (...) actualist model of God’s power. (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)
