In the 1680s, Gottfried Leibniz and Antoine Arnauld engaged in a philosophically rich correspondence. One issue they discuss is modal metaphysics – questions concerning necessity, possibility, and essence. While Arnauld's contributions to the correspondence are considered generally astute, his contributions on this issue have not always received a warm treatment. I argue that Arnauld's criticisms of Leibniz are sophisticated and that Arnauld offers his own Cartesian account in its place. In particular, I argue that Arnauld offers an account of possibility (...) that is actualist, modal actualist and essence-based. (shrink)

There is considerable debate among scholars over whether Descartes allowed for genuine body–body interaction. I begin by considering Michael Della Rocca’s recent claim that Descartes accepted such interaction, and that his doctrine of the creation of the eternal truths indicates how this interaction could be acceptable to him. Though I agree that Descartes was inclined to accept real bodily causes of motion, I differ from Della Rocca in emphasizing that his ontology ultimately does not allow for them. This is not (...) the end of the story, however, since two of Descartes’s successors offered incompatible ways of developing his conflicted account of motion. I contrast the occasionalist view of Nicolas Malebranche that changes in motion derive directly from divine volitions with the non-occasionalist claim of Pierre-Sylvain Regis that such changes derive from a nature distinct from God. In light of Della Rocca’s interpretation, it is noteworthy that the issue of eternal truths is relevant to both alternative accounts. Indeed, Regis took the doctrine that such truths are created to provide crucial support for his alternative to an occasionalist account of body–body interaction. What does not help Della Rocca, however, is that Regis’s view of motion requires a fundamental revision of Descartes’s ontology.

Neste artigo, pretendo examinar a tese cartesiana da livre criação das verdades eternas a partir da conjugação dos atributos divinos que, segundo Descartes, são conhecidos por nós e sua tese de que, entre as verdades eternas livremente criadas por Deus, estão incluídos os princípios lógicos. A partir desse exame, concluo que, até onde o intelecto finito do homem pode conceber, a tese cartesiana da livre criação das verdades eternas envolve ao menos as seguintes teses: a) Deus, por ser infinito e (...) puro pensamento em ato, estabelece necessariamente em si todas as essências e verdades, incluindo essências e verdades que para o intelecto finito parecem impossíveis, já que lhe aparecem como contraditórias; b) ao estabelecer as essências e verdades, Deus instancia algumas (e assim as cria) como conteúdos de ideias inatas nas mentes finitas, que são criadas com estrutura lógica; c) ao estabelecer as essências e verdades, Deus instancia no mundo atual ao menos algumas das essências e verdades não contraditórias instanciadas nas mentes finitas; e d) embora a mente humana finita não as possa conceber clara e distintamente, é certo que Deus instancia no mundo atual ao menos algumas das essências e verdades que aparecem como contraditórias, isto é, instancia no mundo atual ao menos algumas das essências e verdades que para a mente finita aparecem como impossíveis por serem por ela inconcebíveis, o que é confirmado por ao menos dois casos mencionados por Descartes. In this article I intend to examine the Cartesian view on the free creation of the eternal truths considering the conjunction of the divine attributes, which according to the Cartesian thesis, are known to us and his thesis that logical principles are among the eternal truths freely created by God. From this examination I conclude that, as far as the finite intellect of man can conceive, the Cartesian view of the free creation of the eternal truths involves at least the following theses: a) being pure and infinite thinking in action, God necessarily sets in himself all the form of essence and truth, including all essence and truth that for, the finite intellect, seem impossible since they may appear to him as contradictory; b) while establishing all essence and truth, God instantiates some of them (and thus creates some of them) as contents of innate ideas in finite minds, which are created with a logical structure; c) while establishing all essence and truth God instantiates in the actual world at least some of the non-contradictory essences which are instantiated in the finite mind; and d) although the finite human mind cannot conceive it clearly and distinctly, it is certain that God instantiates in the actual world at least some of essence and truth that seem to be contradictory for the human mind, that is, God instantiates at least some of the essences and truths which appear to the finite mind as impossible since inconceivable, which is confirmed by at least two cases mentioned by Descartes.

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.

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)

This paper argues that, for Bernard Nieuwentijt, mathematical reasoning on the basis of ideas is not the same as logical reasoning on the basis of propositions. Noting that the two types of reasoning differ helps make sense of a peculiar-sounding claim Nieuwentijt makes, namely that it is possible to mathematically deduce false propositions from true abstracted ideas. I propose to interpret Nieuwentijt’s abstracted ideas as incomplete mental copies of existing objects. I argue that, according to Nieuwentijt, a proposition is mathematically (...) deducible from an abstracted idea if it can be demonstrated that that proposition makes a true claim about the object that idea forms. This allows me to explain why Nieuwentijt deems it possible to deduce false propositions from true ideas. It also implies that logic and mathematics are not as closely related for Nieuwentijt as has been suggested in the existing secondary literature. (shrink)

I argue that Descartes intended the so-called ontological "argument" as a self-validating intuition, rather than as a formal proof. The textual evidence for this view is highly compelling, but the strongest support comes from understanding Descartes's diagnosis for why God's existence is not 'immediately' self-evident to everyone and the method of analysis that he develops for making it self-evident. The larger aim of the paper is to use the ontological argument as a case study of Descartes's nonformalist theory of deduction (...) and his method of analysis, showing how he conceives the latter as a form of philosophical therapy. (shrink)

Descartes's claim that the eternal truths were freely created by God is fraught with interpretive difficulties. The main arguments in the literature are classified as concerning the ontological status or the modalities of possibility and necessity of the eternal truths. The views of the principal defenders of the Creation Doctrine – Robert Desgabets, Pierre Sylvain Régis, and Antoine Le Grand are contrasted with those of Nicolas Malebranche. In clarifying the theological, ontological, and logical terms of the debate we can see (...) that what was at stake was the objectivity and certainty of the truths of mathematics and physics. I conclude by suggesting that this issue might fruitfully be used to clarify the disparate discussions in the contemporary literature. (shrink)

The old and recent debates on Cartesian essences have focused on the question of whether Descartes is a Platonist or a conceptualist about essences. I argue that this is a false dichotomy. An adequate account of Cartesian essences must accommodate and reconcile two central doctrines and texts in Descartes' philosophy. I will argue that recent conceptualist and Platonist interpretations neither accommodate these doctrines nor reconcile these texts. Such failures are not accidental since Descartes' doctrines of divine creation and simplicity render (...) it impossible for Descartes to be either a conceptualist or a Platonist. Failure to notice this fact explains why there has been no progress on this exegetical issue. (shrink)

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)

ABSTRACTI draw attention to certain differences between how seventeenth‐century philosophers thought about knowledge and how contemporary philosophers think about it. These differences do not strike me as particularly subtle; they are gross enough that we might wonder about the extent to which seventeenthth‐century philosophers and modern philosophers are interested in the same thing. We might also wonder about the extent to which it is helpful to apply the same label—say, ‘epistemology’—to both sets of interests. I think, for example, one might (...) reasonably raise the question, Is there any epistemology, in our sense of the term, in Spinoza or Leibniz? (shrink)

On the assumption that theistic religious commitment takes place in the face of evidential ambiguity, the question arises under what conditions it is permissible to make a doxastic venture beyond one’s evidence in favour of a religious proposition. In this paper I explore the implications for orthodox theistic commitment of adopting, in answer to that question, a modest, moral coherentist, fideism. This extended Jamesian fideism crucially requires positive ethical evaluation of both the motivation and content of religious doxastic ventures. I (...) suggest that, even though the existence of horrendous evil does not resolve evidential ambiguity in favour of atheism, there are reasonable value commitments that would preclude those who hold them from satisfying extended Jamesian fideist conditions for committing themselves to classical theism. I then begin a discussion of a possible revisionary theistic alternative (in the Christian tradition) which – one might hope – may meet those conditions. An earlier, shorter, version of this paper was delivered as a keynote address at the APA Pacific 2007 Mini-Conference on Models of God. (shrink)

Descartes held the seemingly bizarre doctrine that the eternal truths are freely created by God. This 'Creation Doctrine' has been the subject of great misunderstandings and ridicule from philosophers and theologians from the seventeenth century to the present. ;This dissertation is a sympathetic interpretation of Descartes' Creation Doctrine. After first briefly examining some alternative views concerning the relationship between the eternal truths and God, I argue that Descartes is committed to the Creation Doctrine because of his acceptance of traditional theological (...) views concerning the nature of God, in particular, God's simplicity and freedom. I then argue that Descartes' Creation Doctrine, contrary to the claims of some recent commentators, does not entail any bizarre modal theses. For instance, the fact that God could have willed that the eternal truths are false does not entail that there are no necessary truths. I conclude by offering an interpretation of Descartes' explanation of the necessity of the eternal truths. ;We will see that the Creation Doctrine is theologically well-grounded, does not affect ordinary modal claims, and in fact, guarantees the necessity of the eternal truths.

Conception and causation are fundamental notions in Spinoza's metaphysics. I argue against the orthodox view that, due to the causal axiom, if one thing is conceived through another thing, then the second thing causes the first thing. My conclusion forces us to rethink Spinoza's entitlement to some of his core commitments, including the principle of sufficient reason, the parallelism doctrine and the conatus doctrine.

Much ado has been made regarding Descartes's understanding of the creation of what he called the "eternal truths" because he described them, paradoxically, as both the free creations of God, and necessary. While there are many varying interpretations of Cartesian modality, the issue has heretofore been treated in a vacuum, as a niche issue having little import beyond being an interesting puzzle for Descartes Scholars. I argue that this treatment is misguided, and that in order to properly understand Cartesian philosophy (...) at all, one must properly understand Descartes's theory of modality. This, however, is no small feat; in order to understand Descartes's seemingly peculiar view on modality, one must first make sense of what Descartes understood the nature of God to be. One reason for this, I argue, is the systematic nature of Cartesian philosophy; indeed when dealing with a dense inter-connection of philosophical issues, one must move from what is more known in itself to what is more known to us, and not the other way around. I argue that in the literature on Cartesian modality, insufficient attention has been paid to the influence of the French School of Spirituality on the Cartesian notion of the divine. I argue that this influence pushed Descartes to criticize traditional attempts to split the horns of Plato's Euthyphro dilemma as violating a proper understanding of the doctrine of divine simplicity. Descartes's commitment to a radical form of the doctrine of divine simplicity leads him to a version of divine voluntarism wherein all `things' depend on God for their existence, and God cannot have had antecedent reason to prefer the creation of anything over anything else. There is little doubt that Descartes embraced the voluntarist horn of the Euthyphro dilemma, but just what that means for Cartesian modality and philosophy generally remains a contentious issue. I argue that Descartes is best read as what I call an `agnostic quietist' regarding God given textual, historical, and systematic considerations. One virtue of an agnostic quietist reading is that I am able to square the passages where Descartes discusses the inconceivability of God's power with the conclusions reached regarding God's non-deceiving nature in the Meditations and elsewhere. Further virtues that I explore are the effects that a quietist reading has on the Cartesian scientific programme, the infamous mind-body problem, Descartes's seemingly inconsistent view regarding human free-will and Descartes's refusal to engage in "theology." Traditionally, Cartesian epistemology has been understood to be a purely a priori undertaking, which succumbs to deep and insurmountable problems. One of the greatest problems facing the Cartesian was the move from the mind to the world. Simon Blackburn, for example, says of the Cartesian epistemological project in the Meditations that Descartes "has put himself on a desert island from which there is no escape." This view is echoed by, and even motivates some of the contemporary views concerning Cartesian modality. I argue, however, that a proper understanding of the Cartesian doctrine of clear and distinct ideas circumvents this famous problem. By highlighting the proper understanding and application of the doctrine of clear and distinct ideas, I show that such ideas not only guarantee the existence of an external truth-maker, but also that such ideas do not do much more than show that there is a truth-maker. I argue that in instances of clear and distinct perception, the truth of the idea is normatively certain, but what makes it true is yet to be established. In this way, clear and distinct ideas are both powerful, in terms of guaranteeing truth, and relatively unhelpful, in that further work is required in order to determine to what the ideas conform. I argue that this is the case not only for actual truths, but for some clearly intuited truths about possibility. As an illustration of my overall thesis, I address the Cartesian argument for the separability of mind and body, and entertain the various interpretations of Descartes's view of human freedom. I argue that in order to understand Cartesian views on either of these issues, one must first make sense of his modal commitments. In both of these cases Descartes claims that finite minds can know that something is possible, even though what makes it possible is well beyond what they can understand. (shrink)

Central to Descartes’ philosophy is a view about immutable essences and eternal truths. After mentioning a Platonist account of recollection in Meditation V, Descartes declares that the ideas we have of mathematical notions “are not my invention but have their own true and immutable natures” (AT VII, 64/CSM II, 44).Descartes claims that other important philosophical notions, such as God, mind, body, and human free will (AT VII, 68; AT VIII-2, 348; AT III, 383; AT VII, 433, respectively), also have immutable (...) natures or essences. Although Descartes says a good many things about this view, nowhere does he offer definitive doctrine on the matter, and in fact frequently confuses his reader with apparently inconsistent pronouncements about immutable natures and eternal truths. In this essay, I focus on the immutable natures and propose a solution to two of the main problems associated with Descartes’ position, the metaphysical status of immutable natures and the purported indivisibility of their existence as ideas in the mind.
