Spinoza: Truth and Adequacy

Like most, if not all, of his contemporaries, Spinoza never developed a full-fledged philosophy of mathematics. Still, his numerous remarks about mathematics attest not only to his deep interest in the subject (a point which is also confirmed by the significant presence of mathematical books in his library), but also to his quite elaborate and perhaps unique understanding of the nature of mathematics. At the very center of his thought about mathematics stands a paradox (or, at least, an apparent paradox): (...) mathematics provides Spinoza with an epistemic model. Mathematical knowledge is certain (II/138/9 and II/138/9), clear (IV/261/8), and free from teleological thinking (II/79/33), but the objects of mathematical knowledge – i.e., mathematical entities – are nothing but “auxila imaginationis [aids of the imagination],” (IV/57/16 and II/83/15), entities that are not real and merely assist the imagination in carving the world in manner that is suitable to our limited and distortive cognitive capacities.

El articulo examina la aparente discrepancia en el pensamiento de Spinoza entre su teocentrismo epistemológico, según el cual todo es dudoso mientras desconocemos la existencia de Dios, y el principio verum index sui et falsi, según el cual la mera posesión de ideas verdaderas excluye toda incertidumbre. Lejos de contradecirse, estas dos afirmaciones constituyen en Spinoza dos aspectos correlativos del mismo planteamiento gnoseólogico. Se muestra así que la naturaleza divina no es ajena al intelecto humano y que este es capaz (...) de contemplar la realidad desde una perspectiva omnímoda, idéntica a la de Dios. (shrink)

Despite the centrality of ideology critique in the works of Louis Althusser and his students, the Marxian concept of “appearance” as constitutive of the necessary obfuscation of social modes of exchange has not been sufficiently explicated. Furthermore, perceived incompatibility between ideology and commodity fetishism by this group of philosophers has amounted to a critical lacuna in the shape of a materialist theory of the valueform. This essay articulates the concept of appearance as framed by Gilles Deleuze’s concept of expression in (...) an attempt to foreground the structuring relations that immanently determine capital, appearance, and value. By carefully reformulating Marx’s value-form theory through the rationalist metaphysics of Baruch Spinoza, this essay endeavors to produce a value-form theory compatible with the Spinozist Marxist tradition.

Recently the literature dedicated to the Kantian reception of Spinoza has experienced a significant increase. There are several studies dedicated to mapping the presence of the latter in both pre-critical and critical writings of the former, and different are the results achieved by each. Yet, with the exception of a few references to the section in which Spinozism is presented as the only alternative to transcendental idealism, the Critique of Practical Reason is almost never mentioned nor, even less, is it (...) customary to look at it in an attempt to find something that attenuates the contrast between the two philosophies. The aim of this essay is to show how it is precisely in the second Critic, and in particular by introducing the Fact of Reason, that Kant thinks, so to speak, together with Spinoza. Indeed, in 1788 the moral law works as an adequate idea that makes us active causes, and the experience of the freedom procured by the conscience that we have of it is, therefore, very similar to the experience of eternity illustrated by the fifth book of the Ethics.

This book concerns Spinoza's theory of knowledge and closely related issues: Spinoza's conceptions of geometrical figure or shape, number, and observational sci.

Adequate ideas are the fundamental element of Spinoza’s epistemological program. However, a recurrent worry among scholars is that Spinoza’s account of adequate ideas is inconsistent with any finite being ever having one. As I frame it, the problem is that for Spinoza an idea is adequate in a mind only if all its causal antecedents lie within the mind as well. However, it seems there can be no finite mind for which this is true; finite minds come to be and (...) exist within a deterministic causal nexus, and the causal antecedents of every idea in a mind will ultimately stretch far beyond it. I call this the External Cause Objection. I argue that Spinoza appreciated and explicitly answered this concern. According to this reply, adequate ideas do not have causes external to the mind because they do not fall into the category of what Spinoza calls “singular things.” In addition to showing that this coheres with his more specific claims about adequate ideas and his firm belief that finite minds are parts of nature, I argue that the resolution to this problem sheds light on Spinoza’s understanding of what I call absolute agency.

This book interrogates the ontology of mathematical entities in Spinoza as a basis for addressing a wide range of interpretive issues in Spinoza’s epistemology—from his antiskepticism and philosophy of science to the nature and scope of reason and intuitive knowledge and the intellectual love of God. Going against recent trends in Spinoza scholarship, and drawing on various sources, including Spinoza’s engagements with optical theory and physics, Matthew Homan argues for a realist interpretation of geometrical figures in Spinoza; illustrates their role (...) in a Spinozan hypothetico-deductive scientific method; and develops Spinoza’s mathematical examples to better illuminate the three kinds of knowledge. The result is a portrait of Spinoza’s epistemology as sanguine and distinctive yet at home in the new Cartesian and Galilean scientific-philosophical paradigm. (shrink)

ABSTRACT According to Genevieve Lloyd, conatus is manifested in body as a fixed ratio of motion and rest and in mind as increasing adequate understanding. The commentary provides textual analysis to resolve the apparent paradox that bodily stability corresponds to intellectual growth. The activity of adequate ideas and passivity of inadequate ideas are identified as analogues of motion and rest in Spinoza’s philosophy of mind and these are put to work in exploring what is required for increasing one’s adequate understanding: (...) that one can acquire adequate ideas only by extending one’s receptivity to being affected and by forming inadequate ideas. Thus a mind’s ratio between adequate and inadequate ideas is maintained even as it gains and exercises greater power. This appreciation of Spinoza’s epistemology supports Lloyd’s characterisation of his philosophy as “thinking from within the totality of being”. (shrink)

ABSTRACT This commentary defends an interpretation of Spinoza that preserves some key elements of traditional rationalism, in which reason does have an independent path to the truth. While it agrees with Lloyd’s general view, in which reason, imagination, and emotion are more closely tied than the Cartesian scheme, in which reason is distinct from the world of bodies, the paper disagrees with her central claim that reason is constituted by the imagination. It argues that the imagination is effective to the (...) extent that it produces forms of knowledge that are analogous to reason. The paper considers her interpretation of Flaubert and the Biblical prophets and claims that it cannot account for why some forms of the imagination might be mistaken or superior to others. In conclusion, it points out that, while ‘unresolved multiplicity’ might be the predicament of those led by the imagination, Spinoza thinks that reason leads to a common perspective and is a superior guide to life.

This paper offers a new interpretation of the young Spinoza’s method of distinguishing the true ideas from the false, which shows that his answer to the sceptic is not a failure. This method combines analysis and synthesis as follows: if we can say of the object of an idea which simple things underlie it, how it can be constructed out of simple elements, and what properties it has after it has been produced, doubt concerning the object simply makes no sense. (...) The paper also suggests a way in which this methodology connects to the ontology of the Ethics. (shrink)

This paper examines Spinoza’s view on the consistency of mental representation. First, I argue that he departs from Scholastic tradition by arguing that all mental states—whether desires, intentions, beliefs, perceptions, entertainings, etc.—must be logically consistent. Second, I argue that his endorsement of this view is motivated by key Spinozistic doctrines, most importantly the doctrine that all acts of thought represent what could follow from God’s nature. Finally, I argue that Spinoza’s view that all mental representation is consistent pushes him to (...) a linguistic account of contradiction. (shrink)

Spinoza's guiding commitment to the thesis that nothing exists or occurs outside of the scope of nature and its necessary laws makes him one of the great seventeenth-century exemplars of both philosophical naturalism and explanatory rationalism. Nature and Necessity in Spinoza's Philosophy brings together for the first time eighteen of Don Garrett's articles on Spinoza's philosophy, ranging over the fields of metaphysics, epistemology, philosophy of mind, ethics, and political philosophy. Taken together, these influential articles provide a comprehensive interpretation of that (...) philosophy, including Spinoza's theories of substance, thought and extension, causation, truth, knowledge, individuation, representation, consciousness, conatus, teleology, emotion, freedom, responsibility, virtue, contract, the state, and eternity-and the deep interrelations among them. Each article aims to resolve significant problems in the understanding of Spinoza's philosophy in such a way as to make evident both his reasons for his views and the enduring value of his ideas. At the same time, Garrett's articles elucidate the relations between his philosophy and those of predecessors and contemporaries like Aristotle, Hobbes, Descartes, Locke, and Leibniz. Lastly, the volume offers important and substantial replies to leading critics on four crucial topics: the necessary existence of God (Nature), substance monism, necessitarianism, and consciousness.

Spinoza’s Ethics, and its project of proving ethical truths through the geometric method, have attracted and challenged readers for more than three hundred years. In Spinoza and the Cunning of Imagination, Eugene Garver uses the imagination as a guiding thread to this work. Other readers have looked at the imagination to account for Spinoza’s understanding of politics and religion, but this is the first inquiry to see it as central to the Ethics as a whole—imagination as a quality to be (...) cultivated, and not simply overcome. ​Spinoza initially presents imagination as an inadequate and confused way of thinking, always inferior to ideas that adequately represent things as they are. It would seem to follow that one ought to purge the mind of imaginative ideas and replace them with rational ideas as soon as possible, but as Garver shows, the Ethics don’t allow for this ultimate ethical act until one has cultivated a powerful imagination. This is, for Garver, “the cunning of imagination.” The simple plot of progress becomes, because of the imagination, a complex journey full of reversals and discoveries. For Garver, the “cunning” of the imagination resides in our ability to use imagination to rise above it. (shrink)

This book reconstructs Spinoza's theory of the human mind against the backdrop of the twofold notion that subjective experience is explainable and that its successful explanation is of ethical relevance, because it makes us wiser, freer, and happier.

In an unsung yet excellent paper, W.Z. Harvey set out to explain how both Maimonides and Spinoza have similarly problematic views on the nature of the knowledge of good and evil. In it, he proposed an answer to solving the problem. In the many decades since, debates surrounding this topic have flourished. A recent paper by Joshua Parens, his conclusions mark a distinction between Spinoza and Maimonides that threaten to undermine Harvey’s solution to the problem. I will argue that, although (...) Parens’ distinction forces us to revise Harvey’s contention, Harvey’s argument is still generally valid. (shrink)

Michael LeBuffe explains claims about reason in Spinoza's metaphysics, theory of mind, ethics, and politics. He emphasizes the extent to which different claims build upon one another so contribute to the systematic coherence of Spinoza's philosophy.

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

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

Spinoza might solve the Body-Mind problem with parallelism: physical events are correlated instantly by mental events, which are ideas. Everyone has a force needing a direction to create a motion. With adequate knowledge, we can reallocate the Emotion adequately to empower us. Modern Spinozism can be summed up as: full naturalism, radical determinism, theoretical antihumanism, denunciation of methodological individualism, and pure relational approach of human realities. Bringing Spinoza in nowadays analysis of law unfolds two paths of study: law is institutions (...) that redirect emotions; law is a tool for emancipation of passions. This leads to four major consequences: legal power is factual power; normativity is based on positive emotions more than on negative ones such as coercion; legal rules are a factor of autonomy and empowerment; jurisprudence can be a causal science. (shrink)

The article proposes a new solution to the long-standing problem of the universality of essences in Spinoza's ontology. It argues that, according to Spinoza, particular things in nature possess unique essences, but that these essences coexist with more general, mind-dependent species-essences, constructed by finite minds on the basis of similarities that obtain among the properties of formally-real particulars. This account provides the best fit both with the textual evidence and with Spinoza's other metaphysical and epistemological commitments. The article offers new (...) readings of how Spinoza understands not just the nature of essence, but also the nature of being, reason, striving, definitions, and different kinds of knowledge.

This paper begins with a pressing question for contemporary philosophy: What does it mean to read Spinoza’s Ethics today? Before we can address this particular question, we pose another, one possibly prior, question. The question is situated within Spinozism itself. It asks, ‘What does it mean to read, for Spinoza?’ Given Spinoza’s commitment to the theory of parallelism, reading affects both the body and the mind. We first show how an explicit formulation of the three kinds of material bodies allows (...) us to understand the process by which the meaning of a text can affect the body of the reader. We then show how the three kinds of knowledge evince the order in which textual meaning can affect the mind of the reader. We then claim that these tripartite orders map directly onto each other. After demonstrating the structural parallelism at the corporeal and cognitive levels, we return to further characterize the nature of the meaning of the meaning of a text in order to understand what it means to read, for Spinoza. We conclude with an observation about the necessary interrelatedness of metaphysics and ethics. (shrink)

Spinoza’s claims about true ideas are central to the Treatise on the Emendation of the Intellect. It is therefore worth trying to reconstruct what he means when he says that an idea is true. I argue that the three leading interpretations – correspondence, coherence, and causal – don’t explain key passages. I then propose a new interpretation. Roughly, I propose that an idea is true if and only if it represents an essence and was derived in the right kind of (...) way by the intellect from an innate idea of one’s own essence. In the final section I sketch why I believe this interpretation extends to his claims about truth and adequacy in the Ethics. (shrink)

Accusé par un correspondant de considérer sa propre philosophie comme la meilleure de toutes, Spinoza rectifie : il sait seulement qu’est vraie celle qu’il comprend. Mais on ne trouvera chez lui ni réelle thématisation ni véritable définition de l’idée de philosophie, pas plus qu’un programme des connaissances comme s’appliquent à en dresser Bacon, Descartes ou Hobbes. Cet ouvrage enquête alors sur la présence, chez Spinoza, d’une conception précise voire singulière de l’idée de philosophie. Il collecte les indices d’une telle idée (...) conçue comme praxis de distinction ou, selon l’expression Althusser, comme activité de tracer des lignes de démarcation. Mais il établit encore que la philosophie prend elle-même sens en ce geste, et seulement en ce geste, c’est-à-dire par le biais de relations nécessaires avec ce qui a priori n’est pas elle : le vulgaire, l’ignorant, le théologien, le souverain ou même d’autres philosophes. L’idée de philosophie, en d’autres termes, s’autoproduit dans un système de rencontres singulières. En analyser les fruits permet alors de recomposer la nature de la «vraie philosophie» : une pratique de production d’idées et de leur communication. Mais se fait jour, en outre, comme un naturel philosophe, effort s’éprouvant selon une réjouissance propre au «vrai philosophe», déjà sage en vertu de son mouvement de se perfectionner et d’accroître sa puissance.

when reading spinoza’s Ethics,1 one comes upon a particularly disconcerting passage in Part Three. In an explication of two definitions of ‘favor’ (favor) and ‘indignation’ (indignatio), Spinoza writes,I know that in their common usage these words mean something else. But my purpose is to explain the nature of things, not the meaning of words. I intend to indicate these things by words whose meaning is not entirely opposed to the meaning with which I wish to use them. One warning of (...) this should suffice.2The passage cannot but give rise to some bewilderment. First, if Spinoza’s use of words is not “entirely opposed” to the (common) meaning of those words, one wonders to what degree his use of words is in fact .. (shrink)

Adequate and inadequate ideas play a central role in Spinoza’s system. A number of recent commentators have suggested that the internality or externality of an idea’s immediate cause is a necessary and sufficient condition of the idea’s adequacy or inadequacy, respectively. I show that this thesis is subject to counterexample and briefly explore the significance of this critique for recent interpretations. I offer an alternative interpretation on which adequate and inadequate ideas are characterized by the manner in which they grasp (...) their objects. Adequate ideas conceive of their objects as following from God. Inadequate ideas conceive of their objects as affecting the body at a time and place. (shrink)

It is argued first, that Spinoza's Principle of Sufficient Reason (PSR) is best seen as an auxiliary premise and not as an axiom of the Ethics; second, that Spinoza held the PSR to be a self-evident truth that indicates a necessary condition for clearly and distinctly representing the existence or non-existence of a thing; and third, that this interpretation of Spinoza's PSR explains the near absence of the PSR within the demonstrations of the Ethics as well as the importance of (...) the principle in Spinoza's thought.

Spinoza never discusses the scenario of radical skepticism as it was introduced by Descartes. Why not? This paper argues that he chooses a preventive strategy: instead of taking the skeptical challenge as it is and trying to refute it, he questions the challenge itself and gives a diagnosis of its origin. It is a combination of semantic atomism, dualism and anti-naturalism that gives rise to radical doubts. Spinoza attacks these basic assumptions, opting instead for semantic holism, anti-dualism and naturalism. This (...) crucial shift of basic assumptions prevents radical skepticism from arising. To be sure, local doubts are still possible, but the possibility of global doubt is ruled out. The paper examines this preventive strategy, situating it in the historical context and building a bridge to more recent anti-skeptical strategies. (shrink)

" Nous sentons et nous expérimentons que nous sommes éternels. " Cette phrase énigmatique n'est peut-être pas soli-taire : elle appelle - et suppose pour être comprise - toute une problématique spinoziste de l'expérience, peu aperçue mais régissant des pans entiers du système. L'expérience, c'est d'abord la clef de l'itinéraire par lequel, au début de la Réforme de l'entendement, le narrateur arrache à la vie commune les raisons de chercher le vrai Bien. C'est ensuite, dans les champs de l'histoire (lieu (...) de la fortune), de la langue (lieu de l'usage), des passions (lieu de l'ingenium), le signe de tout ce qui paraît échapper à la Raison sans pourtant la contredire. C'est enfin la présence, en tout homme, d'une conscience de la nécessité au sein même de la finitude. Ainsi l'étude de l'expérience permet-elle de voir autrement la Raison elle-même ; de comprendre, aussi, la constitution du système qui apparaît comme une réflexion sur les formes et les moyens de la rationalité.

Naturalism pervades Spinoza’s doctrines of The Ethics, but the contours of it often bewilder us. In this light, I consider the account of falsity, or having a false idea, as presented by Spinoza in Proposition thirty_five of the Second Part, its demonstration, and the subsequent note. Based on my interpretation I argue for the claim that his account has coherence and makes sense. Further, I examine the significance of what Spinoza says about falsity for comprehension of his philosophy overall, especially (...) as regards its contrasts with the philosophy of Descartes.

Approaching the central themes of Spinoza's thought from both a historical and analytical perspective, this book examines the logical-metaphysical core of Spinoza's philosophy, its epistemology and its ramifications for his much disputed attitude towards religion. Opening with a discussion of Spinoza's historical and philosophical location as the appropriate context for the interpretation of his work, the book goes on to present a non-'logical' reading of Spinoza's metaphysics, a consideration of Spinoza's radical repudiation of Cartesian subjectivism and an examination of how (...) Spinoza wanted religion to be understood in the context of his wider thinking and the influence of his non-Christian background. Mason also assesses Spinoza's significance and importance for philosophy now. (shrink)
