Spinoza: Reason

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)

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.

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.

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.

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.

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)

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)

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.

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.

This paper is a discussion of which kinds of knowledge Spinoza himself employs in developing the system of the Ethics. The problem is raised by Professor D. Savan and further discussed by G. H. R. Parkinson. The thesis is (1) that no occurrence of the first kind of knowledge is to be found in the Ethics (against Parkinson), (2) that the main part of the analysis in the Ethics is conducted on the level of the second kind of knowledge (in (...) agreement with Parkinson), and (3) that the third kind of knowledge occurs frequently and plays a most important role in the Ethics (in part against Parkinson). The relation between knowledge and language, the distinction between two types of imagination, or two ways of imagining things, the translation of knowledge of modes of extension into knowledge of the mind, and the relation between the second and third kind of knowledge are main parts of the argument. The third kind of knowledge derives its significance in the Ethics from the definitions and axioms, particularly in Part 1. These definitions and axioms form the basis of the whole system of the Ethics, and at least some of them, it is suggested, belong to the third kind of knowledge. (shrink)
