This book is the fruit of twenty-five years of study of Spinoza by the editor and translator of a new and widely acclaimed edition of Spinoza's collected works.

In the _Fifth Meditation, Descartes introduces a being for which his system appears to leave no room. He clearly and distinctly perceives geometrical properties and concludes that, even though they may not actually exist, their _true and immutable natures exist nonetheless. Here I argue that the wedge that Descartes drives between an object and its true and immutable nature is only temporary and that, in the final analysis, a true and immutable nature of any X is just X itself. Given (...) the analytic method of the _Meditations, it is to be expected that the 'meditator' would not notice any of this in the _Fifth Meditation. He must wait until his epistemic position is more enhanced. (shrink)

With very few exceptions philosophers believe that no account of the doctrine of divine omnipotence is adequate if it entails that God can do what is logically impossible. Descartes is credited with believing otherwise. In his article ‘Descartes on the Creation of the Eternal Truths’ Harry Frankfurt attributes to Descartes the belief that God is ‘a being for whom the logically impossible is possible’. In addition, Frankfurt claims that because of this belief Descartes’ account of God's omnipotence is open to (...) the charge of being incoherent. I will argue that it is wrong to attribute this belief to Descartes and that if his account of divine omnipotence is incoherent, it is incoherent for reasons other than that it entails the possibility of what is logically impossible.

Descartes propounded the allegedly "strange", "peculiar", "curious" and "incoherent" doctrine that necessary truths are made true by God's voluntary act. It is generally held that this doctrine must be kept out of sight while other Cartesian topics are being discussed. This paper offers an interpretation of this Cartesian doctrine under which it comes out as reasonable, consistent with the rest of his philosophy, and possible even true. According to this interpretation--which is more respectful of and close to Descartes's text than (...) is the customary one--Descartes equated the alethic modalities with facts about human intellectual limitations, somewhat in the manner of Wittgenstein. Thus, God created modalities creating humans in the way he did. (shrink)

This essay explores the vexed issue of individual corporeal substance in Descartes' natural philosophy. Although Descartes' often referred to individual material objects as separate substances, the constraints on his definitions of matter and substance would seem to favor the opposite view; namely, that there exists only one corporeal substance, the plenum. In contrast to this standard interpretation, however, it will be demonstrated that Descartes' hypotheses make a fairly convincing case for the existence of individual material substances; and the key to (...) this new found individuation is a long neglected set of passages in the Principles of Philosophy.

Descartes famously endorsed the view that (CD) God freely created the eternal truths, such that He could have done otherwise than He did. This controversial doctrine is much discussed in recent secondary literature, yet Descartes’s actual arguments for CD have received very little attention. In this paper I focus on what many take to be a key Cartesian argument for CD: that divine simplicity entails the dependence of the eternal truths on the divine will. What makes this argument both important (...) and interesting is that Descartes’s scholastic predecessors share the premise of divine simplicity but reject the CD conclusion. To properly understand Descartes, then, we must determine precisely where he diverges from his predecessors on the path from simplicity to CD. And when we do so we obtain a very surprising result: that despite many dramatic prima facie differences, there is no substantive difference between the relevant doctrines of Descartes and the scholastics . Or so I argue. (shrink)

A quick scan of the leading figures in western philosophy reveals that relatively few have made a name for themselves by defending intuitive, natural, and sensible positions. Aristotle is one, and perhaps Aquinas is another. Francisco Suarez, the sixteenth-century Spanish scholastic, would be a third. His invariable working procedure is to give copious consideration to the various ancient and medieval views, and then to find some sensible compromise position. But today Suarez can hardly claim to have a broad readership. Of (...) his fifty-four Metaphysical Disputations, only nine have now been published in English, while his other works remain almost entirely untranslated. This clear and accurate new translation aims to show readers what they have been missing. (shrink)

Despite their influence on later philosophers such as Hume, Malebranche's central arguments for occasionalism remain deeply puzzling. Both the famous ‘no necessary connection’ argument and what I call the epistemic argument include assumptions – e.g., that a true cause is logically necessarily connected to its effect – that seem unmotivated, even in their context. I argue that a proper understanding of late scholastic views lets us see why Malebranche would make this assumption. Both arguments turn on the claim that a (...) volition is the only candidate for a cause, because only a volition can include an effect as its intentional content. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 43.1 (2005) 1-19 [Access article in PDF] God's Immutability and the Necessity of Descartes's Eternal Truths Dan Kaufman Descartes's doctrine of the creation of the eternal truths (henceforth "the Creation Doctrine") has been thought to be a particularly problematic doctrine, both internally inconsistent and detrimental to Descartes's system as a whole. According to the Creation Doctrine, the eternal truths, such as the truths (...) of mathematics and those concerning true and immutable natures, are freely created by God.1 The Creation Doctrine has led several scholars to think that Descartes held (or was committed to) the view that the eternal truths are not necessary truths; in fact, there are no necessary truths if Descartes is correct.2 [End Page 1]In fact, however, Descartes held both of the following.The eternal truths are freely created by God.The eternal truths are necessarily true.That Descartes held (1) is uncontroversial; in fact, it is the characteristic thesis of his Creation Doctrine. However, his commitment to (2) is more controversial. I believe the controversy surrounding (2) arises precisely because Descartes' acceptance of (1) is so uncontroversial. That is, some have thought that his acceptance of (1) eliminates any possibility of accepting (2). This view is mistaken. In several texts, it is clear that Descartes believes that the eternal truths are necessarily true; this is especially noticeable in the 2 May 1644 letter to Mesland (AT IV 118; CSMK 235). The task, then, is to account for the necessity of the eternal truths within the confines of the Creation Doctrine; that is, to explain the fact that (2) is true, given that (1) is true.3 Unfortunately, Descartes says precious little about this issue. To make matters worse, there is a scarcity of treatments of this issue in the literature; and the literature that does address this issue tends to treat it quickly and vaguely, perhaps recognizing the difficulty of addressing it in any detail. In this paper, I attempt to remedy this unfortunate situation.I begin by examining the most prominent interpretation of Descartes's explanation of the necessity of the eternal truths: the Immutability Interpretation.4 This interpretation is given by Margaret Osler and most prominently by Edwin Curley.5 According to this interpretation, the eternal truths are necessarily true because they are created by God, and God's will is immutable. I will show that this interpretation is incorrect: It is either too weak to explain the necessity of the eternal truths or it is too strong in that it would commit Descartes to necessitarianism, [End Page 2] a view he does not hold.6 I also show that some suggestions for salvaging the Immutability Interpretation fall short. In the final section I present an alternative interpretation. My interpretation has a firm basis in Descartes's texts, does not have the shortcomings of the Immutability Interpretation, and has several virtues of its own. 1. Immutability Before examining the role, if any, that God's immutability actually plays in Descartes's explanation of the necessity of the eternal truths, it may be helpful to have a working account of God's immutability. To be immutable is not merely to be unchanging, but rather to be unable to change. That is: I1: x is immutable iff x is essentially unchanging.7We must recognize, however, that there are extrinsic and relational properties that a thing may acquire or lose without any real change in the thing; that is, there are so-called Cambridge changes that something may undergo without thereby being mutable. For example if x is five feet tall at t and x is five foot five at some later time t´, then x has really changed; but if x is not an uncle at t and x is an uncle at some later time t´, then x has not really changed in virtue of acquiring this property. The idea is that there are some properties which are, to use Edward Wierenga's and Nicholas Wolterstorff's term, "change... (shrink)

: Given Descartes's conception of extension, space and body, there are deep problems about how there can be any real motion. The argument here is that in fact Descartes takes motion to be only phenomenal. The paper sets out the problems generated by taking motion to be real, the solution to them found in the Cartesian texts, and an explanation of those texts in which Descartes appears on the contrary to regard motion as real.

Spinoza said that the only extended substance is the whole extended world and that finite bodies are not substances, i.e. are not worthy of a thing-like status in a fundamental metaphysics. He had reasons for this doctrine, though they do not occur in his official ‘demonstration’ that there is only one substance (Ethics 1, proposition 14). One reason was the view that an ultimately thing-like status cannot be accorded to something that is divisible. That was certainly Leibniz’s view, and there (...) are textual grounds for attributing it to Spinoza also, though the evidence for that is somewhat diffuse. But there is also an argument that occurs in a localized manner, in a passage I shall quote below; and my purpose in this paper is to expound it. (shrink)

Most critiques of modernity rest on an inadequate understanding of its complexity. Modernity should be seen in terms of the question that guides modern thought. 77ns is the question of divine omnipotence that arises out of the nominalist destruction of Scholasticism. Humanism, Reformation Christianity, empiricsim, and rationalism are different responses to this question.

Descartes is notorious for holding a strong anti-vacuist position. On his view, according to the standard reading, empty space not only does not exist in nature, but it is logically impossible. The very notion of a void or vacuum is an incoherent one. Recently Eric Palmer has proposed a revisionist reading of Descartes on empty space, arguing that he is more sanguine about its possibility. Palmer makes use of Descartes’ early correspondence with Marin Mersenne, including his commentary on Galileo’s Two (...) New Sciences. I argue that Palmer’s reading is mistaken, and that it relies on an understandable but faulty inference—i.e., that if Descartes considers the implications of an opposing view, he must find it at least coherent. Descartes, as I show from his correspondence and other texts, uses a variety of persuasive strategies, and levels charges of different logical strength, against positions which he takes to be incoherent. Thus we cannot infer from the fact that Descartes argues, e.g., that something is a superfluous theoretical entity, that he admits that entity’s coherence. He often chooses to argue a weaker thesis against an opponent so that he can use an argument to which the opponent is more likely to agree. (shrink)

The Mathematical Principles of Natural Philosophy.

This paper examines Descartes' controversial theory of the creation of eternal truths and the views of modality attributed to Descartes in recent interpretations of it. It shows why attempts to make Descartes' view intelligible by distinctions of different kinds of modality fail to do justice to his theory, which is radical indeed without being incoherent or involving universal possibilism or irrationalism. Descartes' opposition to traditional rationalist views of modality, it suggests, can be seen instead as foreshadowing contemporary views prefixed, logical (...) structure of reality or of the divine intellect.
