In this paper, I argue for a novel reading of Spinoza’s position in his exchangewith Boyle about Boyle’s experiment with nitre. Boyle claimed to have shownthrough experiments that nitre ceased to be nitre after heating. Spinozadisagreed and proposed the alternative hypothesis that nitre has changed itsstate and not its nature. Spinoza’s position was construed in the literature asrational scepticism denying that experiments can yield knowledge ofessences because all sensory experience is underdetermined and open tomultiple interpretations. I argue for an alternative (...) reading of Spinoza’sposition which focuses on Bacon’s notion of crucial instance. According tothis reading, Spinoza did not deny the possibility of knowing byexperimentation whether nitre has changed its nature, he asked for a crucialinstance, i.e. an experiment that would refute the hypothesis that nitre haschanged merely its state. Spinoza’s argumentative strategy shows that,contrary to the mainstream reading, the representational content of sensoryideas can be determined even if it does not represent the essence of theobject: we can know with absolute, rather than merely moral, certaintywhether nitre ceased to be nitre without knowing what nitre is.

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

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 study deals with the matter of three of the most puzzling doctrines of Baruch Spinoza's system, the so-called 'final doctrines', which are intuitive knowledge, intellectual love of God, and the eternity of the (human) mind. Contrary to many commentators, but also in concordance with many others, this account strives to affirm the utmost importance of these doctrines to Spinoza's system as a whole, but mostly to his ethical theory. Focusing specifically on the cultivation of the human mind, the paper (...) offers partial analyses of the central notions of these doctrines and their conceptual contexts. It is argued that the cultivation of the human mind, i.e., its determination to its perfect activity, should be considered as Spinoza's ultimate ethical goal, and that the mind truly only advances to this goal by means of these cognitive, affective, and intellectual transformations of thinking.

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.

Nossa meta é caracterizar alguns aspectos da metodologia científica utilizada por Aristóteles em algumas passagens dos dois primeiros livros do Sobre o Céu e averiguar quais são os principais recursos a que Aristóteles recorre para descobrir os princípios de sua astronomia e para coletar os dados iniciais astronômicos relevantes. Procuraremos mostrar que, para Aristóteles, embora escassos e imprecisos, os dados observacionais ainda têm preferência em relação aos endoxa astronômicos, o que não impede, porém, o emprego de alguns testes dialéticos para (...) o estabelecimento do conhecimento preliminar relevante para a astronomia.

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)

In this article I dispute the claim, made by several contemporary scholars, that Spinoza was a naturalist. ‘Naturalism’ here refers to two distinct but related positions in contemporary philosophy. The first, ontological naturalism, is the view that everything that exists possesses a certain character permitting it to be defined as natural and prohibiting it from being defined as supernatural. I argue that the only definition of ontological naturalism that could be legitimately applied to Spinoza's philosophy is so unrestrictive as to (...) tell us nothing about the content of his ideas. The second, methodological naturalism, is the view that the natural sciences are the best means of finding out substantial truths about the concrete world. I present some historical research showing that Spinoza's way of positioning himself with respect to other philosophers in the Dutch Republic casts very serious doubt on the claim that he was a methodological naturalist. This adds further weight to arguments that have already been made against the naturalist reading of Spinoza. (shrink)

In this article, we will attempt to understand Sellars’ puzzling notion of ‘adequate picturing’ and its relation to the Sellarsian ‘conceptual order’ through Spinoza’s intuitive knowledge. First, it will be suggested that there are important structural similarities between Sellarsian ‘adequate picturing’ and Spinoza’s intuitive knowledge which can illuminate some ‘dark’ and not so well understood features of Sellarsian picturing. However, there remain some deep differences between Sellars’ and Spinoza’s philosophy, especially with regard to their notion of ‘adequacy’ and the sense (...) in which an idea can be said to ‘correspond’ with its object. As a consequence of those differences it turns out that, from a Sellarsian viewpoint, Spinoza’s notion of intuitive knowledge is a version of the myth of the Given. However, Sellars’ own proposed way out of the Myth has problematic consequences by Sellars’ own lights: His sharp distinction between the ‘space of reasons’ level and the level of picturing makes the Sellarsian vision of the ‘stereoscopic fusion’ of those levels virtually unintelligible. Finally, it will be argued that a non-standard interpretation of Spinoza’s intuitive knowledge -proposed in Baltas -, combined with a Sellars-inspired bifurcated understanding of Dreyfusian expert knowledge, can provide the means 1) for constructing a notion of intuitive knowledge that evades the myth of the Given, and, 2) for making full sense of the claim that the ‘space of reasons’ dimension of understanding the world can in principle be fused with the ‘picturing’ dimension and provide us with a single complex coherent experience of reality and our place in it.

Spinoza unequivocally states in the Ethics that intuitive knowledge is more powerful than reason. Nonetheless, it is not clear what exactly this greater power promises in the face of the passions. Does this mean that intuitive knowledge is not liable to akrasia? Ronald Sandler offers what, to my knowledge, is the only explicit answer to this question in recent Spinoza scholarship. According to Sandler, intuitive knowledge, unlike reason, is not susceptible to akrasia. This is because, intuitive knowledge enables the knower (...) to greater power over the passions due to its immediacy, its foundation and because it engenders the boundlessly powerful intellectual love of God. In this paper, I consider to what extent intuitive knowledge is liable to akrasia by exploring whether Sandler's claim can justifiably be attributed to Spinoza. I argue that, given our modal status, it is not plausible to claim that akrasia would never apply to intuitive knowledge. Since intuitive ideas are the ideas of a finite .. (shrink)

In the last part of Ethics Spinoza introduces the doctrine of the intellectual love of God: God loves himself with an infinite intellectual love. This doctrine has raised one of the most discussed puzzles in Spinoza scholarship: How can God have intellectual love if, as Spinoza says, God is Nature itself? After examining existing.approaches to the puzzle and revealing their failures, I will propose a Neo- Confucian approach to the puzzle. I will compare Spinoza's philosophy with Neo-Confucian philosophy and argue (...) that we can develop a new approach to the puzzle by appealing to the comparison. I conclude that the intellectual love of God can be properly understood from different perspectives. From God's perspective it is understood as the creative power of God. From an individual's perspective it is understood as the essence of this very individual. Moreover, once we combine these two perspectives we can reach what I consider to be the correct interpretation of Spinoza' s view: Given that intuitive knowledge and action are one and the same the intellectual love of God should be comprehended not only as man's final fulfillment of freedom through intuitive knowledge, but also as man's self-cultivation in practice. I maintain that a free man, as Spinoza endeavors to become, is equivalent to a Neo-Confucian sage. (shrink)

In this paper, I discuss Spinoza on the proper methods and content of physical science. I start by showing how Spinoza's epistemology leads him to a kind of pessimism about the prospects of empirical and mathematical methods in natural philosophy. While they are useful for life, they do not tell us about nature, as Spinoza puts it, “as it is in itself.” At the same time, Spinoza seems to allow that we have some knowledge of physical things and their behavior. (...) So I go on to outline and critique a few of the accounts of how Spinoza thinks we can do this, focusing on the role of the common notions in physics. In the third section, I discuss the possible contents of physics, for Spinoza, and argue that they are not, as is usually thought, fundamentally Cartesian. I conclude by pointing to some promising directions for future research and suggesting a few heuristics for such research. (shrink)

Scorned by analytic philosophers for much of the twentieth century, the a priori has been newly befriended in recent years. This development is healthy but there is reason to be concerned about how it is unfolding. In particular, it is largely characterized by a certain historical myopia: contemporary philosophers are able to see back to Kant but not much beyond him. While it may be true that the a priori changed with Kant, this in itself provides us with a reason (...) to go back before him. For other conceptualizations of the a priori, all but forgotten now, might help us to meet worries about it that Kant's familiar version cannot. (shrink)

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 the Ethics, Spinoza advances two apparently irreconcilable construals of will [voluntas]. Initially, he presents will as a shorthand way of referring to the volitions that all ideas involve, namely affirmations and negations. But just a few propositions later, he defines it as striving when it is “related only to the mind” (3p9s). It is difficult to see how these two construals can be reconciled, since to affirm or assent to some content is to adopt an attitude with a cognitive (...) (mind-to-world) direction of fit, while to strive to persevere in one’s being would seem to be to adopt an attitude with a conative (world-to-mind) direction of fit. Attempting to achieve consistency by taking striving under the attribute of thought to consist in affirming only pushes the equivocation problem onto the concept of affirmation (Lin 2019). It would seem, then, that Spinoza equivocates on the concepts of will, affirmation, or perhaps both. I defend the univocity of Spinoza’s accounts of will and affirmation, showing that it comports with established accounts of affirmation in early modern philosophy and yields a clear, uniform account of what it means to strive under the attribute of thought, preserving the systematicity of Spinoza’s account of mind in ways that other interpretations do not.
