Like their contemporary counterparts, early modern philosophers find themselves in a predicament. On one hand, there are strong reasons to deny that sensations are representations. For there seems to be nothing in the world for them to represent. On the other hand, some sensory representations seem to be required for us to experience bodies. How else could one perceive the boundaries of a body, except by means of different shadings of color? I argue that Nicolas Malebranche offers an extreme -- (...) and ultimately unworkable -- attempt to solve this riddle. Most commentators claim that Malebranche defends an adverbial theory of sensation, according to which a sensation is merely a way in which an act of sensing happens. The adverbial reading is wrong, or so I argue. Once we arrive at a more accurate reading, we shall see that his position is much more strange than is currently thought. Nevertheless, Malebranche’s view is similar to the adverbial theory in one respect, albeit it at a very high level of generality. His view thus inherits two of the main problems that afflict adverbial theories. Although Malebranche fails to solve them, his ingenious attempts to do so are instructive. (shrink)

The purpose of this essay is exegesis. I explicate Nicolas Malebranche's (1674, 1678, 1688, 1714) concept of intelligible extension. I begin by detailing how the concept matured throughout Malebranche's work, and the new functions it took on within his metaphysical system. I then examine Gustav Bergmann's “axiomatic” interpretation, as well as the criticism of it offered by Daise Radner. I argue that Radner's criticism of the interpretation is only partly successful; some of her objections can be met; others cannot. I (...) then develop a novel interpretation of the concept, given insights from this dispute. I call it the “programmatic interpretation.” I argue that this interpretation coheres well with Malebranche's famous Vision in God thesis, as well as many of his other commitments. I conclude by considering a certain pertinent objection to my proposal, summarizing the dialectic, and forcefully restating my case. (shrink)

Locke’s argument for the primary-secondary quality distinction is compared with Descartes’s argument (in the Principles of Philosophy) for the distinction between mechanical modifications and sensible qualities. I argue that following Descartes, Locke’s argument for the primary-secondary quality distinction is an essentially a priori argument, based on our conception of substance, and the constraints on intelligible bodily interaction that this conception of substance sets.

We argue that the projective geometrical component of the Projective Consciousness Model can account for key aspects of pre-reflective self-consciousness and can relate PRSC intelligibly to another signal feature of subjectivity: perspectival character or point of view. We illustrate how the projective geometrical versions of the concepts of duality, reciprocity, polarity, closedness, closure, and unboundedness answer to salient aspects of the phenomenology of PRSC. We thus show that the same mathematics that accounts for the statics and dynamics of perspectival character (...) also accounts for PRSC. More generally, we argue that introducing higher-level geometrical concepts into the theory of PRSC, and into the theory of consciousness broadly, as the PCM does, promises to break longstanding theoretical impasses and dialectical stalemates.

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)

In the latter half of the 17th century, Antoine Arnauld was a public and private defender of many of the central tenets of Cartesianism. Yet, one issue on which he is surprisingly silent is René Descartes’ claim that God freely created the eternal truths (the Creation Doctrine). Despite Arnauld’s evasion of the issue, whether he holds the Creation Doctrine is one of the most contested issues in Arnauld scholarship. In this paper I offer an interpretation of Arnauld’s position. I argue (...) that Arnauld does not hold what I call the metaphysical version of the Creation Doctrine according to which God in fact freely created the eternal truths. Rather, he holds what I call the epistemic version of the Creation Doctrine according to which we cannot know whether God freely created the eternal truths. (shrink)

Robert Cummins [(1996) Representations, targets and attitudes, Cambridge, MA: Bradford/MIT, p. 1] has characterized the vexed problem of mental representation as "the topic in the philosophy of mind for some time now." This remark is something of an understatement. The same topic was central to the famous controversy between Nicolas Malebranche and Antoine Arnauld in the 17th century and remained central to the entire philosophical tradition of "ideas" in the writings of Locke, Berkeley, Hume, Reid and Kant. However, the scholarly, (...) exegetical literature has almost no overlap with that of contemporary cognitive science. I show that the recurrence of certain deep perplexities about the mind is a systematic and pervasive pattern arising not only throughout history, but also in a number of independent domains today such as debates over visual imagery, symbolic systems and others. Such historical and contemporary convergences suggest that the fundamental issues cannot arise essentially from the theoretical guise they take in any particular case. (shrink)

In response to widespread doubts among professional philosophers (Russell, Horwich, Dietrich, McGinn, Chalmers), Stoljar argues for a ‘reasonable optimism’ about progress in philosophy. He defends the large and surprising claim that ‘there is progress on all or reasonably many of the big questions.’ However, Stoljar’s caveats and admitted avoidance of historical evidence permits overlooking persistent controversies in philosophy of mind and cognitive science that are essentially unchanged since the 17th Century. Stoljar suggests that his claims are commonplace in philosophy departments (...) and, indeed, the evidence I adduce constitutes an indictment of the widely shared view among professional analytic philosophers.

Malebranche argues that ideas are representative beings existing in God. He defends this thesis by an inference to the best explanation of human perception. It is well known that Malebranche’s theory of vision in God was forcefully rejected by philosophers such as Arnauld, Locke, and Berkeley. However, the notion that ideas exist in God was not the only controversial aspect of Malebranche’s approach. Another controversy centered around Malebranche’s view that ideas are to be understood as posits in an explanatory theory. (...) Opponents of this approach, including Arnauld and Locke, held that our talk about ideas was not explanatory but instead merely descriptive: we use the word ‘idea’ to describe phenomena that we observe by reflecting on our own minds. This controversy has not received much attention from scholars, but in the present paper I will show that it was an explicit and important subject of concern for Malebranche, Arnauld, Locke, and Berkeley and that attention to this controversy can illuminate several aspects of these philosophers’ work.

In his dispute with Malebranche about the nature of ideas, Arnauld endorses a form of direct realism. This appears to conflict with views put forward by Arnauld and his collaborators in the Port-Royal Grammar and Logic where ideas are treated as objects in the mind. This tension can be resolved by a careful examination of Arnauld's remarks on the semantics of ‘perception’ and ‘idea’ in light of the Port-Royal theory of language. This examination leads to the conclusion that Arnauld's ideas (...) really are objects in the mind, and not perceptual acts as many commentators hold. What Arnauld denies is that these mental objects are really distinct from the external objects they represent. Instead, Arnauld holds that, by the act of conception, the external objects themselves—not copies—come to be present in the mind and are therefore called ‘ideas’. (shrink)

Most discussions of Spinoza and consciousness—and there are not many— conclude either that he does not have an account of consciousness, or that he does have one but that it is at best confused, at worst hopeless. I argue, in fact, that people have been looking in the wrong place for Spinoza's account of consciousness, namely, at his doctrine of "ideas of ideas". Indeed, Spinoza offers the possibility of a fairly sophisticated, naturalistic account of consciousness, one that grounds it in (...) the nature and capacities of the body. Consciousness for Spinoza, I suggest, is a certain complexity in thinking that is the correlate of the complexity of a body, and human consciousness, for Spinoza, is nothing but the correlate in Thought of the extraordinarily high complexity of the human body in Extension. In this respect, Spinoza anticipates the conception of mind that is presently emerging from studies in the so-called ‘embodied mind’ research program. Moreover, this research program, in turn, may hold out hope for a clearer understanding of some of Spinoza's more difficult claims. CiteULike Connotea Del.icio.us What's this? (shrink)

The paper explores the existential import of universal affirmative in Descartes, Arnauld and Malebranche. Descartes holds, inconsistently, that eternal truths are true even if the subject term is empty but that a proposition with a false idea as subject is false. Malebranche extends Descartes? truth-conditions for eternal truths, which lack existential import, to all knowledge, allowing only for non-propositional knowledge of contingent existence. Malebranche's rather implausible Neoplatonic semantics is detailed as consisting of three key semantic relations: illumination by which God's (...) ideas cause mental terms, creation by which God's ideas cause material substances by a kind of ?ontic privation?, and sensation in which brain events occasion states of mental awareness. In contrast, Arnauld distinguishes two types of propositions ? necessary and contingent ? with distinct truth-conditions, one with and one without existential import. Arnauld's more modern semantics is laid out as a theory of reference that substitutes earlier causal accounts with one that adapts the medieval notion of objective being. His version anticipates modern notions of intentional content and appeals in its ontology only to substances and their modes. (shrink)

Commentators standardly ascribe to Spinoza a belief in an exceptionless conceptual closure of mental and physical realms: no intention can allow us to understand a bodily movement, no bodily injury can make intelligible a sensation of pain. This counterintuitive doctrine, most often now referred to as Spinoza's 'attribute barrier', has weighty repercussions for his views on intelligibility, nature of the mind, identity, and causality. I argue against the standard reading of the doctrine, by showing that it produces an inconsistent epistemological (...) picture, contradicting Spinoza's theory of mind and his commitment to universal intelligibility. The alternative account I propose is also philosophically more compelling and plausible as an account of thought in its essential intentionality. (shrink)

The employment by seventeenth-century natural philosophers of stock theological notions like creation, immensity, and eternity in the articulation and justification of emerging physical programs disrupted a delicate but longstanding balance between transcendent and immanent conceptions of God. By playing a prominent (if not always leading) role in many of the major scientific developments of the period, God became more intimately involved with natural processes than at any time since antiquity. In this discussion, I am particularly concerned with the causal and (...) spatio-temporal relations between God and nature in the seventeenth century as recent scholarship has revealed how dramatically traditional conceptions of these relations were transformed by philosophers and scientists like Descartes, Malebranche, More, and Newton.

Mental imagery (varieties of which are sometimes colloquially refered to as “visualizing,” “seeing in the mind's eye,” “hearing in the head,” “imagining the feel of,” etc.) is quasi-perceptual experience; it resembles perceptual experience, but occurs in the absence of the appropriate external stimuli. It is also generally understood to bear intentionality (i.e., mental images are always images of something or other), and thereby to function as a form of mental representation. Traditionally, visual mental imagery, the most discussed variety, was thought (...) to be caused by the presence of picturelike representations (mental images) in the mind, soul, or brain, but this is no longer universally accepted.

It is plausible to think that before the emergence of terms like “consciousness” and “Bewusstsein,” philosophers and scientists relied on intuitions about phenomena of subjective experience that we would now classify as “conscious.” In other words, pre-modern thinkers availed themselves of one or another concept of consciousness as they developed their theories of mind, perception, representation, the self, etc., although they did not attend to consciousness in its own right. In the early modern period, terminology of consciousness emerges to pick (...) out concept(s) of consciousness. This brings with it an occasion for philosophical disagreements concerning consciousness among contemporaries, on the one hand, and an occasion for us as interpreters of historical authors to better assess their views on consciousness, on the other.

I do not think that the world or the sciences would ever have suggested to me any philosophical problems. What has suggested philosophical problems to me is things which other philosophers have said about the world or the sciences. (G.E. Moore, 1942, p. 14).

The chapter argues from an ethology-inspired internalist perspective that ‘colour’ is not a homogeneous and autonomous attribute, but rather plays different roles in different conceptual forms underlying perception. It discusses empirical and theoretical evidence that indicates that core assumptions underlying orthodox conceptions are grossly inadequate. The assumptions pertain to the idea that colour is a kind of autonomous and unitary attribute. It is regarded as unitary or homogeneous by assuming that its core properties do not depend on the type of (...) ‘perceptual object’ to which it pertains and that‘colour per se’ constitutes a natural attribute in the functional architecture of the perceptual system. It is regarded as autonomous by assuming that it can be studied in isolation of other perceptual attributes. More generally, the chapter argues on the bases of corresponding empirical and theoretical evidence that perception cannot be understood as the ‘recovery’ of physical world structure from sensory structure by input-based computational processes. Rather, the sensory input serves as a kind of sign for biologically relevant aspects of the external world that activates biologically given conceptual forms with their internal parameters. Although the sensory input is a causally necessary requirement for the activation of conceptual forms, the perceptual computations triggered are under the control of an internal programme based on a set of conceptual forms.

In this paper, I defend a novel interpretation of Antoine Arnauld’s conception of God, namely a ‘partially hidden’ conception of God. I focus on divine simplicity and whether God acts for reasons. I argue that Arnauld holds the view that: God, God’s action and God’s attributes are (i) identical, and (ii) conceptually distinct, but that (iii) there are no conceptual priorities among them. Next, I argue that Arnauld’s view about whether God has any type of reasons is agnosticism, but that (...) there are certain types of reasons we know that God does not have, e.g., practical reasons.
