Spinoza: Reason

I argue alongside some other scholars that there is a plausible reading of Spinoza’s philosophy of suicide which holds both of the following tenets: first, that suicides occur because of external conditions, and second, that there are at least some suicides which are rational. These two tenets require special attention because they seem to be the source of significant tension. For Spinoza, if one’s cognitions are to be the most adequate, they must be “disposed internally” (E2p29s/G II 114), or determined (...) more from one’s own mental nature than from “fortuitous encounters” with other things (E2p29s/G II 114). It may seem there is a conflict, then, in saying both that there are rational suicides in the Spinozist framework, and that suicides must always be a result of external conditions: it seems a suicide simply cannot be rational if it is the result of external conditions. But this tension, it will be shown, can be dissolved. Once this tension is dealt with, I offer some brief closing arguments. I explain how this reading of Spinoza’s philosophy of suicide can satisfy a call for new suicide research which avoids forms of over-individualism and epistemic injustice, and which encourages us to abolish oppressive conditions that lead to rational suicides.

In this paper I make four claims. First, there is an apparent contradiction in Spinoza’s theory of justice. On the one hand, in the Tractatus Theologico-Politicus (1670), he argues that justice is entirely conventional and depends on the ruler’s decision. On the other hand, in the later and unpublished Tractatus Politicus (1677), he claims that man really is a social animal and that we can articulate ideal forms of justice on that basis. Second, to address this apparent inconsistency, we need (...) to look at Spinoza’s use of early modern scholastic metaphysics. Although he rejects scholastic natural law theory, he has adopted another concept from the scholastics that is crucial for his theory: the notion of a ‘being of reason’ (ens rationis). Third, if we consider justice as a kind of being of reason, then we can resolve the apparent contradiction in Spinoza’s approach. I shall argue that concepts of justice are imaginative ‘beings of reason.’ They are products of convention that are not derived from general features of the world but from a particular set of circumstances. Fourth, Spinoza’s social ontology of political concepts like justice has some distinct advantages for contemporary theory. This approach shows how we might be able to provide a framework to integrate politics and natural science without reducing one to the other. (shrink)

This article addresses Steven Nadler’s response to my objections to his reading of Spinoza’s free person (homo liber). Nadler argues that there are no clear and significant differences between the free person and the wise person (vir sapiens) in their character or in the role theyplay in Spinoza’s moral philosophy; in fact, they are one and the same. I begin by critically examining three inferences which Nadler’s reading in part relies on. I then address the differences between the contexts in (...) which Spinoza explicitly invokes the free person and the wise person. I argue that even though there may not be significant differences between the free person and the wise person in terms of their character and comportment, there is still reason to think that the free person plays a particular role in Spinoza’s moral philosophy—one which does not hinge on the attainment of the cognitive and affective excellence represented by the wise person at the end 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.

Spinoza reasons about impossibilities on a regular basis. But he also says they're unthinkable and that reasoning is a mental process. How can he do this? The paper defends a linguistic account of counterpossible inferences in Spinoza's geometrical method.

In this paper, the main features of Spinoza’s conception of Reason are laid out. First, how Reason differs on the one hand from opinion and imagination and on the other hand from intuitive knowledge. After that the validation of Reason is considered. As I interpret Benedict de Spinoza, even finite subjects enjoy freedom of Reason. I will give the reasons for this doctrine which seems to be inconsistent with Spinoza’s universal determinism. One of the most fascinating aspects of Spinoza’s rationalism (...) is that the acts of reason are intrinsically motivating in bringing joy to the thinker. I will try to make sense of that view. In the concluding section of the paper, I try to make sense of how this affective feature of reasoning as an intrinsically joyful activity leads to rational love of God which, if things go well, leads to intellectual love of God in which our blessedness or salvation lies.

There is longstanding interpretive dispute between commentators over Spinoza’s commitment to necessitarianism, the doctrine that all things are metaphysically necessary and none are contingent. Those who affirm Spinoza’s commitment to the doctrine adhere to the necessitarian interpretation whereas those who deny it adhere to what I call the semi-necessitarian interpretation. As things stand, the disagreement between commentators appears to have reached an impasse. Notwithstanding, there seems to be no disagreement among commentators on the question of necessitarianism’s philosophical plausibility as a (...) metaphysical view: the doctrine is wildly untenable. This consensus view is more relevant to the interpretive debate than few have recognized, since leading semi-necessitarian commentators take the doctrine’s alleged absurdity to be one of the most compelling reasons (if not the most compelling reason) to prefer their reading over the necessitarian interpretation: for, as a matter of methodological principle, great philosophers like Spinoza should not be ascribed ridiculous views in the absence of better evidence. -/- This dissertation seeks to defend Spinoza’s commitment to necessitarianism on both the interpretive and philosophical fronts. I argue not only that the necessitarian interpretation of Spinoza is more plausible than the semi-necessitarian interpretation on textual grounds, but that Spinoza’s necessitarianism is a serviceable philosophical view whose tenability has been almost entirely overlooked and perfunctorily rejected. The principal basis upon which I build this defense is Spinoza’s rich and fascinating view of essences—what I simply refer to as his essentialism. Spinoza’s essentialism forms the bedrock of his metaphysics and is significant not least because it underlies and informs doctrines like his necessitarianism. Spinoza’s essentialism supplies resources to answer not just interpretive problems associated with necessitarianism, but philosophical challenges to the plausibility of the doctrine. My defense of Spinoza’s necessitarianism on philosophical grounds also offers a novel way of getting past much of the current interpretive impasse among commentators by effectively undercutting the methodological motivation for the semi-necessitarian reading. In addition to my defense on the interpretive front, then, my defense on the philosophical front provides supplementary reason to a fortiori favor the necessitarian reading of Spinoza. (shrink)

ABSTRACT Spinoza has often been cited as a classic example of the philosophical category of ‘rationalism’; and there is indeed much about his philosophy that can seem to warrant that classification. This essay will argue that it is nonetheless a simplification, which can cloud some of the most important and interesting insights that can be gained from reading Spinoza now. Although it is true that his treatment of human knowledge emphasized the exercise of reason, his crucial—and frequently misunderstood—concept of ratio (...) was much richer and more nuanced than the common understanding of ‘rationalism’ can capture. The essay seeks to clarify Spinoza’s version of human reason, elaborating its interconnections with imagination and emotion; and its positioning within the totality of Nature. It draws on comparisons with Pascal—and on consideration of Flaubert’s responses to Spinoza’s works—to illuminate what is distinctive in Spinoza’s account of human reason. What emerges, it is argued, is important—not only for contemporary philosophy, but more broadly for the understanding of conceptual aspects of current issues associated with the status of human beings within the natural world.

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)

In this paper, I argue that Spinoza holds a perspectivalist view of mereological composition, a form of anti-realism. The paper has two parts: In the first half of the paper, I introduce interpretive puzzles for the standard realist reading of Spinoza’s mereology. In the second half of the paper, I discuss Spinoza’s positive view on mereological composition and present a perspectivalist reading that avoids the interpretive puzzles.

Genevieve Lloyd’s Spinoza is quite a different thinker from the arch rationalist caricature of some undergraduate philosophy courses devoted to “The Continental Rationalists”. Lloyd’s Spinoza does not see reason as a complete source of knowledge, nor is deductive rational thought productive of the highest grade of knowledge. Instead, that honour goes to a third kind of knowledge—intuitive knowledge (scientia intuitiva), which provides an immediate, non-discursive knowledge of its singular object. To the embarrassment of some hard-nosed philosophers, intellectual intuition has an (...) affective component; it is a form of love, and ultimately given that human beings are finite modes of God/Nature (Deus sive Natura), it is a form of the intellectual love of God (amor Dei intellectualis). Some philosophers do not know what to make of this mysterious aspect of Spinoza’s philosophy, which is nonetheless firmly anchored in a reading of Part V of the Ethics. Nonetheless, this note will insist with Lloyd’s “Reconsidering Spinoza’s Rationalism” that such doctrine is an integral part of Spinoza’s philosophy. Moreover, it will be shown that Spinoza is well aware of the limitations of reason (ratio) in gaining scientific knowledge of the world and requires intuition precisely because of the inability of reason to represent individuals in their full particularity. Imagination too has a role to play in shaping scientific knowledge, although reason performs a vital critical role in disciplining and liberating the human mind from inadequate imaginary ideas. The result is an interpretation of Spinoza’s epistemology as both rationalist and intuitionist. DOI: 10.1080/24740500.2021.1962652. (shrink)

ABSTRACT Genevieve Lloyd’s assessment of Spinoza’s rationalism shows how imagination and sensibility are integrated with reason in his metaphysics and equally makes clear how his philosophy illuminates a number of aesthetic works and political situations. This response considers the limitations of the aesthetic analogy she draws from Flaubert and also queries the contrast she sees between Spinoza’s account of reason and finitude and Pascal’s account of the same. Turning from Pascal, it concludes with a consideration of Spinoza’s response to Augustine’s (...) doctrine of original sin in the Political Treatise in order to indicate some problems that stem from a vision of politics grounded in a Spinozist metaphysics of multiplicity.

Andrea Sangiacomo offers a new understanding of Spinoza's moral philosophy, how his views significantly evolved over time, and how he himself struggled during his career to develop a theory that could speak to human beings as they actually are--imperfect, passionate, and often not very rational.

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)

En su famoso Tratado Teológico-Político, Spinoza ofrece un método de interpretación de las Escrituras con la finalidad de que, a través de su aplicación, el lector pueda capturar objetivamente el sentido de los textos y de ese modo no incurrir en el mismo error que los teólogos y filósofos cristianos o judíos que confunden el ámbito de la fe con el ámbito de la razón. Ahora bien, en la medida en que leemos los textos sagrados y los interpretamos utilizando el (...) método propuesto por Spinoza, también estamos utilizando la razón. De este modo, cabe preguntarse –siguiendo a Zac– ¿cómo es posible que aun utilizando un método elaborado por la razón se puedan mantener separados el dominio de la razón y la fe sin que esto implique una invasión del primero sobre el segundo? Así, nuestro objetivo en el presente trabajo es examinar el modo en que Spinoza entiende que se realiza la aplicación de la razón en el proceso hermenéutico. Con vistas a este fin, luego de presentar los rasgos generales del método hermenéutico spinoziano, examinaremos críticamente la lectura propuesta por Zac, lo cual nos servirá como trampolín para presentar nuestra propia interpretación.

Baruch Spinoza (1632-1677) is considered to be one of the most prominent representatives of traditional European humanism and liberalism. In the next breath, however, we might add that his humanism was a form of modern humanism, which often uncritically overestimated human capacities and capabilities, leading to many ideological, but also practical failures of humanity. This paper aims to reevaluate Spinoza's rationalist model of human nature in the context of the "shared" rational nature of humans, which is characterized by a broadly (...) anthropological approach. In Spinoza's thought, a human being is not regarded merely as a rational being (or thinking subject, for that matter), but is considered in his complexity, including his affectivity, corporeality, sociality, and - above all - morality. The ideal of free and rational humanity is not an abstract concept, but an expression of real possibilities regarding the development of humankind's innate potential. (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.

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.

This chapter investigates Spinoza's conception of reason, focusing on (i) the difference between reason and the imagination, and (ii) the difference between reason and intuitive knowledge. The central interpretive debate this chapter considers is about the scope of rational cognition. Some commentators have argued that it is only possible to have rational cognition of properties that are universally shared, whereas intuitive knowledge may grasp the essences of particular individuals. Another prominent interpretation is that reason differs from intuition only in virtue (...) of its form or manner of apprehension, and not in virtue of the content or ideas it apprehends. However, authors on both sides of the debate have held that reason is incapable of grasping singular things. After summarizing the debate, this chapter presents an argument that Spinozan reason is not blind to particulars: it is (at least sometimes) capable of grasping the causal structure that characterizes an individual.

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 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)

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", à quoi ça sert? Et comment s'en servir? En particulier, comment penser la mise à l'épreuve du rationalisme spécifique dont il est le nom? L'objectif de ce travail est de contribuer à une réévaluation non seulement du rôle de la pratique dans la pensée de Spinoza, mais encore du système lui-même, de sa capacité à s'adapter et à communiquer avec des domaines tels que les sciences expérimentales, l'histoire, la politique ou la médecine. A travers les concepts et problèmes, tels (...) qu'ils sont formulés dans ses textes, mais également leur utilisation contemporaine, il s'agit ici d'analyser l'articulation de la philosophie de Spinoza au champ de l'action humaine, dans ses dimensions éthique, sociale, cognitive et affective - et d'apprécier la puissance de la rationalité qui en est le fondement. Les auteurs viennent d'horizons différents : professeurs, docteurs, doctorants, étudiants ou érudits originaires de divers pays, ils proposent dans les articles ici présentés des approches variées et originales des problèmes qu'ils traitent, offrant ainsi au lecteur un aperçu de la vitalité des réflexions que suscite aujourd'hui l'oeuvre de Spinoza.

This paper outlines the role of the bodily essence in Spinoza’s epistemology. Spinoza maintains in the Ethics that the power of the imagination depends on bodily affections and it explains the inadequateness of imaginative ideas. However, Spinoza also exploits the capabilities of the human body to work out his account of common notions, which grounds the adequate knowledge provided by reason. Moreover, the essentia corporis plays a crucial role in the fifth part of the Ethics. Indeed, the “eternal part” of (...) the mind depends on the adequate idea of the eternal essence of the human body. By connecting this idea with other ideas, the mind has the power of ordering its ideas according to the intellect. Thus, the mind increases the number of the ideas it conceives of sub specie aeternitatis. In this sense, the bodily essence is not only the ground of Spinoza’s epistemology but also of Spinoza’s doctrine of the eternity of the mind. (shrink)

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

Does Spinoza present philosophy as the preserve of an elite, while condemning the uneducated to a false though palliative form of ‘true religion’? Some commentators have thought so, but this contribution aims to show that they are mistaken. The form of religious life that Spinoza recommends creates the political and epistemological conditions for a gradual transition to philosophical understanding, so that true religion and philosophy are in practice inseparable.

In this dissertation, I explore the distinction between reason (ratio) and intuitive knowledge (scientia intuitiva) in Spinoza’s Ethics in order to explain the superior affective power of the latter over the former. In addressing this fundamental but relatively unexplored issue in Spinoza scholarship, I suggest that these two kinds of adequate knowledge differ not only in terms of their method, but also with respect to their content. I hold that unlike reason, which is a universal knowledge, intuitive knowledge descends to (...) a level of particularity, including the adequate knowledge of one’s own essence as it follows directly from God, which is a superior form of self-knowledge. Since, for Spinoza, there is an intrinsic relationship between the pursuit of knowledge and how we live our lives, my interpretation of these two ways of knowing is that they are at the same time two ways of living.

Spinoza presents a picture of the good human life in which being rational and being reasonable or sociable are mutually supporting: the philosopher makes the best citizen, and citizenship is the best route to philosophy and adequate ideas. Crucial to this mutual implication are the roles of religion and politics in promoting obedience. It is through obedience that people can become "of one mind and one body" in the absence of adequate ideas, through the presence of shared empowering imaginations and (...) emotions. (shrink)

This important book examines Spinoza's moral and political philosophy. Specifically it considers Spinoza's engagement with the themes of Stoicism and his significant contribution to the origins of the European Enlightenment. Firmin DeBrabander explores the problematic view of the relationship between ethics and politics that Spinoza apparently inherited from the Stoics and in so doing asks some important questions that contribute to a crucial contemporary debate. Does ethics provide any foundation for political theory and if so in what way? Likewise, does (...) politics contribute anything essential to the life of virtue? And what is the political place and public role of the philosopher as a practitioner of ethics? In examining Spinoza's Ethics, his most important and widely-read work, and exploring the ways in which this work echoes Stoic themes regarding the public behaviour of the philosopher, the author seeks to answer these key questions and thus makes a fascinating contribution to the study of moral and political philosophy.

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)

Spinoza resolves the tension between reason and revelation by granting reason complete authority and autonomy in all philosophical and natural matters, and by denying revelation any claims to knowledge. Despite this dramatic partisanship, he attempts to make this solution attractive to believers by creating a hermeneutic that allows a limited claim to knowledge for revelation. This article attempts to explain how he arrived at this strategy and why he believed it would succeed.
