Consider a circle and a pair of its semicircles. Which is prior, the whole or its parts? Are the semicircles dependent abstractions from their whole, or is the circle a derivative construction from its parts? Now in place of the circle consider the entire cosmos (the ultimate concrete whole), and in place of the pair of semicircles consider the myriad particles (the ultimate concrete parts). Which if either is ultimately prior, the one ultimate whole or its many ultimate parts?

The official definitions that appear at the beginning of four of the five parts of the "Ethics" do not include an account of "existence." However Spinoza does provide a definition of “existence” in the scholium to proposition 45 of Part 2. This is an odd place for such an important doctrine, and all the more so given that the account there differs from anything resembling commonsense. In this paper I show that, for Spinoza, to exist is to be eternal. Existence (...) in the strict sense is eternal existence. (shrink)

Spinoza’s Ethics must contain some of philosophy’s most baffling statements. All things are animate; the order and connection of ideas is the same as the order and connection of things: what would I be committed to in agreeing with these doctrines? His austere mode of exposition, sparing of illustrations and discursive explanations, ensures that any answer must be highly speculative.His weakness for dark sayings seems to have communicated itself to some of his best-known commentators. Of course where a philosopher’s thought (...) is itself opaque one would be unreasonable to expect lucidity in a commentator’s exposition of it. However he has been described as holding puzzling, to my mind unintelligible opinions on subjects concerning which, as far as I can see, his own statements more naturally suggest a much clearer and more comprehensible interpretation. There are problems enough in understanding his thought without adding needlessly to the list. I think there has been such an addition in discussion of his doctrines about the causal relationship between God and finite creatures, and this paper is devoted to suggesting another account of his thought on that topic which combines, I think, the advantages of being more intelligible and a more natural construction to place on his own statements, than the set of opinions generally laid at his door.

This paper examines some aspects of Spinoza's metaphysics of the essences of modes.2 I situate Spinoza's use of the notion of essence as a response to traditional, Aristotelian, ways of thinking about essence. I argue that, although Spinoza rejects part of the Aristotelian conception of essence, according to which it is in virtue of its essence that a thing is a member of a kind, he nevertheless retains a different part of such a conception, according to which an essence is (...) some structural feature of a thing which causally explains other, non-essential features. I go on to develop an account of Spinoza's metaphysics of essence, according to which essences, what he sometimes calls formal essences, are produced by the divine essence prior to and independent of the creation of finite modes, and according to which essences are the formal or exemplar causes of finite modes. I then argue that finite modes, in virtue of the formal essences which they actualize, are genuine causal relata. Finally, I offer some speculations about Spinoza's answer to the question, "Why, in a necessitarian cosmos filled with formal essences, should there be temporal finite modes at all?". (shrink)

In part I of this paper I argue that on his theory of the mind as the idea of an actually existing body Spinoza is unable to account for the ability of the mind to have adequate knowledge, and I suggest that his theory of the eternity of the mind can be viewed as his solution to this problem. In part II I deal with the question of the meaning of ‘eternity’ in Spinoza, in regard both to God and the (...) human mind, and I sketch a line of thought which I believe may have provided him with further motivation for his theory that a part of the mind is eternal.

Spinoza's Mediate Infinite Mode TAD M. SCHMALTZ IN PART I of the Ethics, Spinoza argued that a modification is infinite just in case it either "follows from the absolute nature of any attribute of God" or "follows from some attribute of God, as it is modified by such a modification" that is infinite. 1 The main purpose of this argument is to bolster the claim later in this text that a finite modification can follow from a divine attribute only insofar (...) as that attribute is modified by another finite modification. 2 Thus it is understandable that in the section that contains the argument Spinoza did not actually affirm the existence of the two kinds of infinite modifications he mentioned, which following standard practice I call "immediate infinite modes" and "mediate infinite modes," respectively.3 Yet in this section he did 'E IP21,D-22,D, G II 65-66/Curley 429-3 o.

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.

Metaphysical rationalism, the doctrine which affirms the Principle of Sufficient Reason (the PSR), is out of favor today. The best argument against it is that it appears to lead to necessitarianism, the claim that all truths are necessarily true. Whatever the intuitive appeal of the PSR, the intuitive appeal of the claim that things could have been otherwise is greater. This problem did not go unnoticed by the great metaphysical rationalists Spinoza and Leibniz. Spinoza’s response was to embrace necessitarianism. Leibniz’s (...) response was to argue that, despite appearances, rationalism does not lead to necessitarianism. This paper examines the debate between these two rationalists and concludes that Leibniz has persuasive grounds for his opinion. This has significant implications both for the plausibility of the PSR and for our understanding of modality. (shrink)

A central difficulty in the way of understanding Spinoza's metaphysical system is that of reconciling two apparently contradictory theories of the causation of finite modes found in his Ethics. The easiest way to present the problem is to place these two accounts side by side.A. All things which follow from the absolute nature of any attribute of God must forever exist, and must be infinite; that is to say, through that attribute they are eternal and infinite. A thing which has (...) been determined to any action was necessarily so determined by God. Together, these propositions entail that God is a necessary and sufficient condition for the occurrence of any action, and that anything so determined is eternal and infinite. Compare these implications with the following.B. An individual thing or a thing which is finite and has determinate existence cannot exist nor be determined to action unless it be determined to existence and action by another cause which is also finite and has a determinate existence; and again this cause cannot exist nor be determined to action unless by another cause which is also finite and determined to existence and action, and so on, ad infinitum.

Spinoza claims both that a thing’s essence is identical to power, and that emotions are fundamentally variations in this power. The conjunction of these two theses creates difficulties for his metaphysics and ethics alike. The three main worries concern the coherence of Spinoza’s accounts of essence, diachronic identity, and emotional “bondage,” and put in question his ability to derive ethical and psychological doctrines from his metaphysical claims. In response to these difficulties, this paper offers a new interpretation of Spinoza’s account (...) of affects and his doctrine of the identity of power and essence. It shows that what is fundamental to his ontology of affects is the relation of modification or determination, a relation central to his ontology more generally. The paper argues that we cannot simply identify power and essence but should instead take affects to modify or determine essences as particular exercises of power (particular desires, appetites, and volitions). That is, Spinozistic essences should be viewed as intrinsically determinable, with affects supplying the determinations, and as consisting not in rigid sets of determinate properties, but in ranges of variable properties.

Spinoza's doctrine of the eternity of the mind is often understood as the claim that the mind has a part that is eternal. I appeal to two principles that Spinoza takes to govern parthood and causation to raise a new problem for this reading. Spinoza takes the composition of one thing from many to require causal interaction among the many. Yet he also holds that eternal things cannot causally interact, without mediation, with things in duration. So the human mind, since (...) it is the idea of a body existing in duration, cannot have an eternal part. In order to solve this problem, I propose an aspectual reading of Spinoza's doctrine of the eternity of the mind: the mind itself is eternal, under one of its aspects. (shrink)

everyone loves superheroes. superheroes, of course, have incredible powers; they can leap tall buildings in a single bound, excel in combat, and have X-ray vision. But, in addition, superheroes have a kind of simplicity of motive and focus that makes them pure and comprehensible in the way in which the people we actually know rarely are. For Superman it is about Truth, Justice, and the American Way. For Batman it is all about fighting evil: defeating the Joker, the Riddler, and (...) other nefarious characters. For Spiderman it is an outsized sense of mission: “With great power comes great responsibility.” Superheroes are superhuman individuals, who have a simple philosophy of life that motivates their every action.

Spinoza's Ethics is one of the most remarkable, important, and difficult books in the history of philosophy: a treatise simultaneously on metaphysics, knowledge, philosophical psychology, moral philosophy, and political philosophy. It presents, in Spinoza's famous 'geometric method', his radical views on God, Nature, the human being, and happiness. In this wide-ranging 2006 introduction to the work, Steven Nadler explains the doctrines and arguments of the Ethics, and shows why Spinoza's endlessly fascinating ideas may have been so troubling to his contemporaries, (...) as well as why they are still highly relevant today. He also examines the philosophical background to Spinoza's thought and the dialogues in which Spinoza was engaged - with his contemporaries, with ancient thinkers, and with his Jewish rationalist forebears. His book is written for the student reader but will also be of interest to specialists in early modern philosophy. (shrink)

Readers of Spinoza's philosophy have often been daunted, and sometimes been enchanted, by the geometrical method which he employs in his philosophical masterpiece the Ethics. In Meaning in Spinoza's Method Aaron Garrett examines this method and suggests that its purpose, in Spinoza's view, was not just to present claims and propositions but also in some sense to change the readers and allow them to look at themselves and the world in a different way. His discussion draws not only on Spinoza's (...) works but also on those of the philosophers who influenced Spinoza most strongly, including Hobbes, Descartes, Maimonides and Gersonides. This controversial book will be of interest to historians of philosophy and to anyone interested in the relation between form and content in philosophical works. (shrink)

Yitzhak Melamed here offers a new and systematic interpretation of the core of Spinoza's metaphysics. In the first part of the book, he proposes a new reading of the metaphysics of substance in Spinoza: he argues that for Spinoza modes both inhere in and are predicated of God. Using extensive textual evidence, he shows that Spinoza considered modes to be God's propria. He goes on to clarify Spinoza's understanding of infinity, mereological relations, infinite modes, and the flow of finite things (...) from God's essence. In the second part of the book, Melamed relies on this interpretation of the substance-mode relation and the nature of infinite modes and puts forward two interrelated theses about the structure of the attribute of Thought and its overarching role in Spinoza's metaphysics. First, he shows that Spinoza had not one, but two independent doctrines of parallelism. Then, in his final main thesis, Melamed argues that, for Spinoza, ideas have a multifaceted structure that allows one and the same idea to represent the infinitely many modes which are parallel to it in the infinitely many attributes. Thought turns out to be coextensive with the whole of nature. Spinoza cannot embrace an idealist reduction of Extension to Thought because of his commitment to the conceptual separation of the attributes. Yet, within Spinoza's metaphysics, Thought clearly has primacy over the other attributes insofar as it is the only attribute which is as elaborate, as complex, and, in some senses, as powerful as God.

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)

This paper argues that Spinoza does not take extension in space to be a fundamental property of physical things. This means that when Spinoza calls either substance or a mode “an Extended thing”, he does not mean that it is a thing extended in three dimensions. The argument proceeds by showing, first, that Spinoza does not associate extension in space with substance, and second, that finite bodies, or physical things, are not understood through the intellect when they are conceived as (...) extended in space. I conclude by articulating some suggestions about where we should go from here in trying to understand Spinoza’s account of the attribute of extension and of the physical world. (shrink)
