This book analyses the concept of scientific explanation developed by French disciples of Descartes in the period 1660-1700. Clarke examines the views of authors such as Malebranche and Rohault, as well as those of less well-known authors such as Cordemoy, Gadroys, Poisson and R'egis. These Cartesian natural philosophers developed an understanding of scientific explanation as necessarily hypothetical, and, while they contributed little to new scientific discoveries, they made a lasting contribution to our concept of explanation--generations of scientists (...) in subsequent centuries followed their lead.

This book deals with a neglected episode in the history of logic and theories of cognition: the way in which conceptions of inference changed during the seventeenth century. The author focuses on the work of Descartes, contrasting his construal of inference as an instantaneous grasp in accord with the natural light of reason, with the Aristotelian view of inference as a discursive process. Gaukroger offers a new interpretation of Descartes`s contribution to the question, revealing it to be a significant advance (...) over humanist and late Scholastic conceptions. He argues that Descartes's account played a pivotal role in the development of our understanding of the nature of inference. (shrink)

In his paper on transcendental intersubjectivity in Husserl, which refers mainly to the Fifth Cartesian Meditation, Schutz (1966a) marks out four stages in Husserl's argument and finds what are for him insurmountable problems in each stage. These stages are: (1) isolation of the primordial world of one's peculiar ownness by means of a further epoche; (2) apperception of the other via pairing; (3) constitution of objective, intersubjective Nature; (4) constitution of higher forms of community. Because of the problems (...) Schutz encounters in each of these stages, he concludes that Husserl's theory is unacceptable (Schutz, 1966a, p.82). Having already proved that it is unacceptable, he now explains why these problems arise in Husserl's theory. Intersubjectivity, says Schutz, is "a datum of the life-world," (1966a, p.82) not a transcendental problem. In other words, intersubjectivity must be dealt with as a problem of the life-world of the natural attitude, not a "problem of constitution which can be solved within the transcendental sphere." (Schutz, 1966a, p.82). There is no such thing as transcendental intersubjectivity, if by that is meant intersubjectivity of a plurality of transcendental egos. The role of transcendental phenomenology in the problem of intersubjectivity is to explicate within the transcendental reduction the sense: "intersubjectivity in the life-world." Husserl was diverted from this proper role of phenomenology--in his words, to "explicate the sense which this world has for us prior to all philosophy" (trans. and quoted by Schutz from "Cartesianische Meditationen, para. 62, in fine," in Schutz, 1966a, p.82)--because of the unobtrusive transformation of sense of his concept of constitution from that of explication and clarification to "creation," in the sense of providing an ontology of the lifeworld. The fact that phenomenology is in principle incapable of doing this lies behind the failure of Husserl's theory of intersubjectivity (Schutz, 1966a, pp.83-84). Unlike Schutz, I will deal with this general issue explicitly in the context of the stages in Husserl's argument and Schutz's objections. It seems to me that Husserl does remain within the sphere of clarification of sense, but to do explication and clarification of certain "senses" results inevitably in doing a kind of ontology.

The utilization of Western canonical thinkers to inform and understand thinkers from India and China is nothing new. More specifically, it is very tempting for a Western-trained philosopher to explain the Buddhist conception of the self by reference to David Hume; both seem to be bundle theories. Moreover, in making such a comparison we seem to get a solution to the puzzle that Hume leaves at the end of A Treatise of Human Nature concerning personal identity. Briefly, Hume holds (...) that we are simply bundles of perceptions. He then admits that he has nothing to hold the perceptions together. The Buddhist conception of the self is as a bundle of five aggregates (skandhas) that are continually changing. In the Buddhist .. (shrink)

The problem of Cartesian dualism is viewed as falling under a more general problem: the problem of human unity. This problem is both ancient and modern: whether a human being is a substantial unity of soul and body or merely a contingent one. I compare Aristotle's and Descartes's response to this problem. My thesis is that an important factor in generating Cartesian dualism is the rejection implicit in Descartes's metaphysical codification of the new mathematical science of nature, (...) namely, the rejection of Aristotle's radical teleological concept of nature. It is argued that the modern intractable problem of the relation of mind to body turns historically and metaphysically on the Cartesian substitution of the mathematically refined concept of body--three-dimensional extension--for the once-influential Aristotelian teleological concept of corporeal substance.

Descartes's conception of matter changed the account of physical nature in terms of extension and related quantitative terms. Plants and animals were turned into species of machines, whose natural functions can be explained mechanistically. This article reflects on the consequences of this transformation for the psychology of human soul. In so far the soul is rational it lacks extension, yet it is also united with the body and affected by it, and so it is able to act on extended (...) matter. The article examines Descartes's concept of scientia and his different uses of nature, and argues that there is much more continuity between Aristotelian and Cartesian psychology than is usually recognized when it comes to an explanation of the functions of the embodied human soul. If this makes psychology unfit for inclusion in the new science of nature, its object is still a natural phenomenon and has an important place within scientia as Descartes conceived of it. (shrink)

Although Descartes’ natural philosophy marked an important advance in the development of modern science, many of his specific concepts of science have been largely discarded, and consequently neglected, since their introduction in the seventeenth century. Many critics over the years, such as Newton (in his early paper De gravitatione), have presented a series of apparently devastating arguments against Descartes' theory of space and motion; a generally negative historical verdict which, moreover, most contemporary scholars accept. Nevertheless, it is also true that (...) most historians and philosophers of science have not sufficiently investigated the viability and effectiveness of the case against Cartesian space and motion. This book explores the success of the arguments against Descartes’ theory of space and motion by determining if it is possible to formulate a Cartesian theory of science that can avoid the problems raised by Newton, as well as by a host of other past and contemporary philosophers either sympathetic or hostile to the overall design of Cartesian science. In particular, if Descartes' theory of motion can be reconciled with his hypotheses on dynamics, then a Cartesian can successfully resolve the difficulties imposed by his critics. This book comprises, therefore, a sustained attempt to construct a consistent “Cartesian” spacetime theory: i.e., a theory of space and time that incorporates Descartes’ various theories of physics and nature without falling into the kinds of problems and contradictions as charged by, for example, Newton.

Purpose. To consider the personal nature of Cartesian metaphysics. Its implementation involves: a) outlining methodological changes in the philosophy of the twentieth century; b) analysis of ways to interpret anthropological component of philosophizing in Descartes studies; c) appeal to Descartes’ texts to clarify the authentic form of his interpretation of metaphysics. Theoretical basis. I base my view of Descartes’ legacy on the conceptual positions of phenomenology, existentialism and hermeneutics. Originality. Based on Descartes’ own concept of teaching, the (...) author substantiates the personal nature of Cartesian metaphysics. Important prerequisites for its comprehension are attention to the ethical motive as the driving force of philosophizing and recognition of the importance of the poetic worldview. The idea of the basic role of poetics finds its meaningful confirmation in the texts of the philosopher, who interprets the main areas of philosophy as the forms of art. Conclusions. Based on his own vision of anthropology and metaphysics as the forms of completion of the revolution initiated by Copernicus, the author defends the idea of the constitutive presence of personality in Descartes’ metaphysics. In the process of studying the research literature, methodological guidelines are outlined in the form of the importance of personal determination of the search for truth, the key role of ethical motive and art as components of philosophizing. The thesis about the poetic form of presentation of metaphysics by Descartes as a form of fixation of its personal dimension is substantiated. (shrink)

We routinely speak of Newton’s laws in classical mechanics without really knowing how Newton understood such laws. This article clarifies some of the ontological, epistemological, and theological presuppositions underpinning his conception of the laws of nature. After introducing the Cartesian background (2), we examine the Newtonian view of laws of nature in three respects, namely: the character of laws of nature in the context of the rules for natural philosophy (3); the emanative conception of space and (...) time in _De Gravitatione_; (4); and the interpretation of laws of nature in terms of Leibnizian mechanisms or Berkeleyan principles (5). Our analysis highlights crucial philosophical elements of Newton’s view of laws of nature, which contributed to shape the directions that predominated in successive investigations (6). (shrink)

This slight volume contains three short essays by the author: “The Idea of Nature In Contemporary Physics”, “Atomic Physics and Causal Law”, and “Classical Education”. Much more than half of the book is given over to a selection of brief readings from Kepler, Galileo, Newton, Huygens, D’Alembert, De la Mettrie, Ostwald, Hertz, and a short historical review by de Broglie of the evolution of quantum mechanics. These readings are meant to illustrate the author’s overall theme which appears to be (...) this: the development of modern science has been marked by a progressive change in the concept of nature. The mediaevals regarded Nature as God’s handiwork: “it would have been thought senseless to ask questions about the material world without reference to God”, Between Galileo and Newton a quite new outlook arose which encouraged the belief that an accurate and exhaustive account of Nature could be made in mathematical terms which made reference only to matter and motion. This was the mechanist view of Nature, which led logically to materialism. But modern physics has shown the inadequacy of this view. “The object of research is no longer nature itself, but man’s investigation of nature”. “Nature itself cannot be known”, only “man’s relationship with nature”. The uncertainty principle proves that an “objective” picture of Nature is impossible. The observer and the observed system cannot be clearly separated, and thus we must give up the “Cartesian” distinction between a world of “objective processes in space and time and a mind in which these processes are mirrored”. Thus, we no longer regard “nature” as God’s handiwork nor as an objective space-time-matter manifold but either as the “footprint of man” upon an unknowable substratum, or else as “the transparent clarity of a mathematics that no longer describes the behaviour of elementary particles but only our knowledge of this behaviour”. There is no “philosophy of nature” properly speaking; our knowledge of “nature”, such as it is, is derived from a philosophical consideration of science. (shrink)

This paper aims to provide an explication of the meaning of ‘analysis’ and ‘synthesis’ in Descartes’ writings. In the first part I claim that Descartes’ method is entirely captured by the term ‘analysis’, and that it is a method of theory elaboration that fuses the modern methods of discovery and confirmation in one enterprise. I discuss Descartes’ methodological writings, assess their continuity and coherence, and I address the major shortcoming of previous interpretations of Cartesian methodology. I also discuss the (...) Cartesian method in the context of other conceptions of scientific method of that era and argue that Descartes’ method significantly transforms these conceptions. In the second part I argue that mathematical and natural-philosophical writings exhibit this kind of analysis. To that effect I examine in Descartes’ writings on the method as used in mathematics, and Descartes’ account of the discovery of the nature of the rainbow in the Meteors. Finally, I briefly assess Descartes’ claim regarding the universality of his method.Author Keywords: Cartesian method; Theory elaboration; Analysis; Synthesis; Simple natures; Rainbow. (shrink)

It is common to assume that Descartes did not have a conception of an object's matter density independently of its size, but this is a rather incomplete assessment of the early modern natural philosopher's theory. Key to our understanding of Descartes's physics is a consideration of the ratios between the quantities of the different types of matter in which an object consists. As these ratios determine the degree of an object's porosity and elasticity, they also affect in Descartes's theory the (...) phenomena of gravity and weight. (shrink)

Neo-Cartesian approaches to belief place greater evidential weight on a subject's introspective judgments than do neo-behaviorist accounts. As a result, the two views differ on whether our absent-minded and weak-willed actions are guided by belief. I argue that simulationist accounts of the concept of belief are committed to neo-Cartesianism, and, though the conceptual and empirical issues that arise are inextricably intertwined, I discuss experimental results that should point theory-theorists in that direction as well. Belief is even less closely (...) connected to behaviour than most contemporary functionalists allow. (shrink)

While the Academic sceptics followed the plausible as a criterion of truth and guided their practice by a doxastic norm, so thinking that agential performances are actions for which the agent assumes responsibility, the Pyrrhonists did not accept rational belief-management, dispensing with judgment in empirical matters. In this sense, the Pyrrhonian Sceptic described himself as not acting in any robust sense of the notion, or as ‘acting’ out of sub-personal and social mechanisms. The important point is that the Pyrrhonian advocacy (...) of a minimal conception of ‘belief’ was motivated by ethical concerns: avoiding any sort of commitment, he attempted to preserve his peace of mind. In this article, I argue for a Cartesian model of rational guidance that, in line with some current versions of an agential virtue epistemology, does involve judgment and risk, and thus which is true both to our rational constitution and to our finite and fallible nature. Insofar as epistemic humility is a virtue of rational agents that recognise the limits of their judgments, Pyrrhonian scepticism, and a fortiori any variety of naturalism, is unable to accommodate this virtue. This means that, in contrast to the Cartesian model, the Pyrrhonist does not provide a satisfactory answer to the problem of cognitive disintegration. The Pyrrhonist thus becomes a social rebel, one that violates the norm of serious personal assent that enables the flourishing of a collaborative and social species which depends on agents that, however fallible, are accountable for their actions and judgments.

This study is the first work ever to interpret the Meditations as theodicy. I show that Descartes' attempt to define the role of God for man's cognitive fallibility in so far as God is the creator of man's nature, is a reiteration of an old Epicurean argument pointing out the incongruity between the existence of God and evil. The question of the nature and origin of error which Descartes addresses in the First Meditation is reformulated in the Fourth (...) Meditation into broader considerations about the nature and scope of human freedom. ;The point of gravity of my thesis is Descartes' conceptions of human freedom and divine liberty. Since the conception of human freedom is the reversal of the doctrine of divine liberty, I analyze the two conceptions as two sides of the same problem--the problem of man's relation to God, or the problem of the relation of finitude to Infinity. I show that Descartes' quest for Certitude--which runs parallel to his attempt to overcome the problem of an evil deity--can be reformulated into the problem of creation. I present the problem of error as the problem of evil, and the problem of human will I present as the problem of human freedom, and the search for Certitude I interpret as the vindication of God's goodness and omnipotence, that is, theodicy. ;There are several points which are essential for Cartesian metaphysics, and which, as I demonstrate, Descartes borrowed from St. Augustine: the doctrine of the eternal truths , the conception of human freedom, the theory of error and the explanation of the will's propensity towards error , and the account of human nature. It is my contention that as much as Descartes insisted on the timelessness of his philosophy, what he had to say on the relationship between God and man is a reflection of the 17th c. theological debates which were fought by the Augustinians and the Molinists and were expressed by Descartes in the language and categories created by St. Augustine.

This paper relates the concept of relevance to its biological foundations by combining Alfred Schutz’s social phenomenology and Helmuth Plessner’s theory of organic life and philosophical anthropology. Relevance interlinks human sign use with the human “lifeworld” (Husserl) as a whole. The biological foundations of relevance, in turn, interlink that lifeworld with the “world of life” that includes us among other lifeforms. I analyze human relevance as an interplay of two tendencies, termed “closedness” and “openness,” that underlies our production of (...) “meaning” (Schutz). Relevance in this general sense involves not only the mind, but also the body of homo sapiens. To provide a unified theoretical framework, I reconstruct Plessner’s “philosophical biology.” According to Plessner, organic life consists in a tension between closedness and openness. This tension unfolds through the “levels” of plants, animals, and humans. Plessner’s analysis of humans as “excentric” animals helps explain the two tendencies that drive human relevance and distinguish our experience from that of our closest animal relatives. At the same time, Plessner traces a robust continuity between us and other lifeforms. The human “level” merely makes “explicit” certain elements (including the Cartesian distinction between “mind” and “body”) that all organisms implicitly possess. (shrink)

This essay critically considers scientific and metaphorical understandings of the body and embodiment. It employs interrogates and employs the concepts of embodiment, ego, bodily intentionality, and anorexia from a phenomenological perspective. It considers the battery of concepts regarding embodiment: soma (the shape of the body), sarx (the flesh of the body) and pexis (the body and soul in unity). While Soma and sarx are the objective body, they are explained by the natural sciences. Pexis is the 'unobjective' body; it is (...) subjective, and it is to be studied as a subjective phenomenon. To understand pexis means to understand that the body does not finish with the skin but is connected to its surroundings. There is also a consideration of the possibilities of the body under Heidegger's idea of protention, which refers to the transformation of the body into an instrument. When the body is conceived of as an instrument or object anorexia is seen as an illness only of embodiment as soma . A richer alternative is the idea that anorexia is an illness of existence that can be explained by Heidegger's discussion of embodiment via the concept of dasein. (shrink)

This paper attempts some integration of two perspectives on questions about rationality and irrationality: the classical conception of irrationality as sophism and themes from the romantic revolt against Enlightenment reason. However, since talk of "reason" and "the irrational" often invites rigid dualities of reason and its opposites (such as feeling, intuition, faith, or tradition), the paper turns to "intelligence" in place of "reason," thinking of human intelligence as something less abstract, less purely theoretical, and more firmly rooted in practice, including (...) communicative practice. "Intelligence" is "reason" naturalized. -/- . (shrink)

In this article, our aim is to examine the place of “reality” in Richard Rorty’s thought in view of the important and key discussion of language in the philosophy of this thinker. In other words, we know that with the occurrence of the “linguistic turn” in the middle of the twentieth century, the relationship between language and reality has become one of the central debates of philosophy, especially analytical philosophy, and has become of particular importance. Is it language that determines (...) the external reality for us? Is knowing the world outside the mind possible only through the possibilities that language gives us? And to what extent does the structure of language affect our cognitive pattern? These are only a part of the linguistic concerns that have occupied the minds of contemporary philosophers. The main concern and problem of the present article, which has been approached using a descriptive-analytical method, is to examine the relationship between language and reality in Richard Rorty’s thought and to show how he defends the linguistic structure of having reality. Rorty, following an analytical philosophy that, in addition to detailed analyses of traditional philosophical concepts, like the concepts of truth, meaning, necessity, etc. and by changing the discussion from experience to discussion from language in the direction of pragmatizing the basic principles of positivism, believes that it is trans-lingual and trans-temporal. The common denominator that Plato found in the outside world and transferred to man in the Cartesian-Kantian tradition is sought in analytic philosophy in language, and so analytic philosophers continue to pursue the traditional philosophy project of providing a trans-historical and eternal framework for the accurate representation of the world. Rorty tries to overcome this view of analytical philosophers with a Darwinist and pragmatic view of language and under the influence of philosophers such as Wittgenstein.For Darwinists, language is a tool among other tools that gives its users the ability to better and more efficiently adapt to their environment and meet their needs. For the likes of Wittgenstein and like-minded people, despite their many and sometimes profound differences, language had an important and pivotal place with its eventual and possibility feature. Influenced by thinkers such as Wittgenstein, and in the context of his Darwinist and pragmatic approach to language, Rorty attributes certain characteristics to language that can be said to influence his whole thought. Firstly, he considers language as a tool like other tools and, therefore, considers it to have no fixed nature and identity. Given that it is not possible to leave the language and on the other hand language has a poetic and metaphorical character, the function of language cannot be a representation of reality and reality can never be available to us naked and as independent of language and descriptions. Therefore, from Rorty’s point of view, reality is a linguistic and constructed matter of language that we humans have invented in cooperation with each other and in accordance with our historical-cultural situation and needs. Of course, Rorty’s point in saying that reality is made by language is by no means that we create reality arbitrarily and as we wish; rather, what is happening is that we are responding to an external stimulus, a response of various sentence types that manifests itself as linguistic reactions.

Abstract Descartes's theory of volition as expressed in his Passions of the Soul is analyzed and outlined. The focus is not on Descartes's proposed answers to questions about the nature and processes of volition, but on his way of formulating questions about the nature of volition. It is argued that the assumptions underlying Descartes's questions have become ?intellectual strait?jackets? for all who are interested in volition: neuroscientists, philosophers and psychologists. It is shown that Descartes's basic assumption?that volition causes (...) change in the brain/mind, not in the world around us?has set in train a series of ?themata? that have dominated studies of the will, severely curtailing our understanding. It is then shown that these Cartesian themata are so limiting and confusing that a number of internally contradictory ideas have actually become mainstays of most theories of volition; in particular, the concepts of unconscious sensations and of involuntary volitions.

In lieu of an abstract, here is a brief excerpt of the content:Commentary on “Non-Cartesian Frameworks”Rom Harré (bio)There are three points in Dr. Berger’s paper that seem to me to call for immediate comment:1. There is the familiar (but in Berger’s case, only a partial) misunderstanding of the upshot of the third phase of Wittgenstein’s private-language argument. Having shown that expressive and descriptive discourse are radically different, and that expressive discourse can be learned only in contexts of action in (...) which there are natural expressions of personal feeling, experience, and so on, Wittgenstein goes on to show that whatever furnishes the mind, it is not thing-like. He does this by showing that “sameness” of thoughts and feelings cannot be spelled out in the same terms as sameness of things, that is, in terms of numerical and qualitative identity. Yet there is a proper use for the concept of sameness of thoughts and feelings. It is to be found in the role that expressions of feelings and declarations of thoughts play in the language games that constitute a form of life. There is no “unresolved tension,” as Berger seems to think. Although pains are not thing-like, they do have a location, do endure, and do differ from one another.The introduction of the powerful expressive/descriptive distinction is the key to the fallacies of representationalism. Expressive acts do not represent but descriptive acts might. But we can draw on the demonstration that mental “somethings” are not thing-like to eliminate that possibility. The root of representationalism is the seventeenth-century conception of the mind as a container of mental entities: ideas. Ideas are to psychology what atoms are to physics. According to Hume, ideas are copies of impressions. In that disastrous thesis, representationalism was born, as a generalization of Locke’s grounding principle that the ideas of primary qualities resembled primary qualities. The cure for this complex mesh of mistakes must be deeply philosophical. It must not be confined to easy criticisms of Locke’s resemblance doctrine, not yet to more subtle Berkleyan strictures on the supposed distinction between ideas and qualities. It must cut at the very deepest assumption of representationalism—that there are mental entities. And on that matter, Wittgenstein’s analysis will, one hopes, prove to be final.2. With representationalism cast onto the midden of history, what account are we to give of mentation? In a sense, Wittgenstein’s insights abolish the inner/outer distinction, an offshoot of the concept of the container-mind. But they leave standing the distinction between what is done privately and what is done publicly. Yet these domains must be of the same nature, since in the expressive use of signs, we find a holism encompassing what we feel and our disposition to express it. Linguistic substitutes for natural forms [End Page 185] of expression must share that holism. But there are no natural expressions of propositional thoughts. Why? Because we are capable of private propositional thinking just insofar as we have mastered public uses of the instruments of propositional thought. These instruments are cultural products.The practice of psychotherapy can be nothing other than discursive. The quotations concerning praxis that Berger offers are disconcertingly vague. To add, as Berger does, that we must take theory into account does not cure the vagueness. We do not know what Berger takes theory to be, only that it is not theory as physicists have it; i.e., systems of hypotheses about hidden processes which bring about that which can be observed. Following Wittgenstein one step farther, we can say that the only thing that could be theory-like in the enterprises of psychotherapists would be grammars. Grammars express the often unformulated norms of discourses. Psychoanalytic theories could then be addressed as expressions of the norms of certain kinds of discourses. Incorporating a “theory” would then be nothing but determining to adopt a certain grammar in one’s therapeutic discourses. Freed of the idea that one of some set of theories must be true and preferred to all others, one is free to adopt and adapt grammars to occasions. Some grammars are tied to natural expressions and so to the ethology of the human form of life... (shrink)

Descartes' conception of facultive inference is of a simple, primitive, unanalyzable, unmediated, unjustifiable "mental operation by which one grasps connections between one's ideas," in contrast to Aristotle's discursive inference consisting in "spelling out and analyzing its steps". Gaukroger shows why Descartes takes Aristotelian syllogistic to be merely presentative of material already known, and thus takes deduction to be only a way of ordering and displaying this knowledge. For Descartes, only synthesis leads to new knowledge. Thus it is a mistake to (...) give an "apriorist and deductivist interpretation of Descartes's method... whereby all scientific knowledge is... deduced from the cogito". One "problem with a purely deductive approach... is... that... first principles take us to every possible world". To settle which account is of the actual world, we must resort to experiment. Also leading to a nondeductive method in science is Descartes' doctrine of God's creation of truths which means that "human knowledge can no longer be modeled in any way on divine knowledge". Descartes' three-part problem-solving method, then, is to pose the problem in quantitative terms, test the solutions experimentally, and incorporate the solution into his system of natural philosophy.

This paper outlines the influence of Cartesian dualism on the foundations of medicine.The notion of a real distinction between the mental and physical, particularly the mechanistic conception of the human body, made possible the development of the natural sciences as well as scientific medicine, not hampered any longer by the risk of colliding (...) with religion or Church.

This book aims at reconciling the emerging conceptions of mind and their contents that have, in recent years, come to seem irreconcilable. Post-Cartesian philosophers face the challenge of comprehending minds as natural objects possessing apparently non-natural powers of thought. The difficulty is to understand how our mental capacities, no less than our biological or chemical characteristics, might ultimately be products of our fundamental physical constituents, and to do so in a way that preserves the phenomena. Externalists argue that the (...) significance of thought turns on the circumstances of thinkers; reductionists hold that mental characteristics are physical; eliminationists contend that the concept of thought belongs to an outmoded folk theory of behavior. John Heil explores these topics and points the way to a naturalistic synthesis, one that accords the mental a place in the physical world alongside the non-mental. (shrink)

Through an exploration of theoretical physics, this paper suggests the need for regrounding natural science in phenomenological philosophy. To begin, the philosophical roots of the prevailing scientific paradigm are traced to the thinking of Plato, Descartes, and Newton. The crisis in modern science is then investigated, tracking developments in physics, science's premier discipline. Einsteinian special relativity is interpreted as a response to the threat of discontinuity implied by the Michelson-Morley experiment, a challenge to classical objectivism that Einstein sought to counteract. (...) We see that Einstein's efforts to banish discontinuity ultimately fall into the “black hole” predicted in his general theory of relativity. The unavoidable discontinuity that haunts Einstein's theory is also central to quantum mechanics. Here too the attempt has been made to manage discontinuity, only to have this strategy thwarted in the end by the intractable problem of quantum gravity. The irrepressible discontinuity manifested in the phenomena of modern physics proves to be linked to a merging of subject and object that flies in the face of Cartesian philosophy. To accommodate these radically non-classical phenomena, a new philosophical foundation is called for: phenomenology. Phenomenological philosophy is elaborated through Merleau-Ponty's concept of depth and is then brought into focus for use in theoretical physics via qualitative work with topology and hypercomplex numbers. In the final part of this paper, a detailed summary is offered of the specific application of topological phenomenology to quantum gravity that was systematically articulated in The Self-Evolving Cosmos (Rosen 2008a).

The concept of the mind in philosophy encompasses a diverse range of theories and perspectives, examining its immaterial nature, unitary function, self-activity, self-consciousness, and persistence despite bodily changes. This paper explores the attributes of the mind, addressing classical materialism, dualism, and behaviorism, along with contemporary theories like functionalism and computational functionalism. Key philosophical debates include the mind-body problem, the subjectivity of mental states, and the epistemological and conceptual challenges in understanding other minds. Contrasting views from Aristotle, Descartes, Wittgenstein, (...) and modern philosophers like U.T. Place, Gilbert Ryle, and Hilary Putnam are analyzed. The paper also discusses the implications of these theories on our understanding of mental phenomena, consciousness, and the nature of human experience. (shrink)

There is a familiar story about Spinoza on which his substance monism arises straightforwardly from Descartes’ own conception of substance, which the latter combines—not entirely consistently—with substance pluralism. I argue that this story is mistaken: substance pluralism is fully consistent with Descartes’ conception of substance; it is also consistent with his claim that the term ‘substance’ is non-univocal. In defense of these claims, I argue that Descartes denies, whereas Spinoza accepts, that causation precludes the kind of independence that is characteristic (...) of substance; further, I show how Descartes’ denial is based on his view that causal relations do not belong to the natures of their relata, whereas Spinoza’s acceptance follows from his commitment to an intimate link between causation and conception, which Descartes also rejects.

This paper addresses the question regarding the relation between capitalism and nature, on the one hand, and that of the continued existence of life, including humankind, on earth in light of the disturbing evidence that has emerged since the early 1970s, concerning massive environmental degradation, on the other. It is argued that the evidence of such destruction is there for every one to see; what is less obvious – in fact, mostly ignored or denied – is the connection between (...) capital as a process which either grows, or dies, and the devastating effect of such uncontrollable growth on geo-ecology (where a distinction is made between ecology and environment in terms of the relations of interdependence by which the former is characterised). Ironically, as far back as 1972 the ‘Club of Rome' warned against the dangers of ‘unlimited growth'. The paper draws substantially, but not exclusively, on the work of Joel Kovel, who argues in favour of what he terms eco-socialism as the best kind of alternative to capitalism. Needless to say, this entails an understanding of the latter, in an encompassing sense as a state of being, instead of in a narrow economistic sense. It also requires that one should distinguish clearly between a mechanistic conception of nature (the Cartesian) that seems to legitimize its exploitation for human use and eventual degradation, on the one hand, and another (Kantian) conception which makes room for the inscrutability of a natural purposiveness that transcends human cognition.

The concept of the mind in philosophy encompasses a diverse range of theories and perspectives, examining its immaterial nature, unitary function, self-activity, self-consciousness, and persistence despite bodily changes. This paper explores the attributes of the mind, addressing classical materialism, dualism, and behaviorism, along with contemporary theories like functionalism and computational functionalism. Key philosophical debates include the mind-body problem, the subjectivity of mental states, and the epistemological and conceptual challenges in understanding other minds. Contrasting views from Aristotle, Descartes, Wittgenstein, (...) and modern philosophers like U.T. Place, Gilbert Ryle, and Hilary Putnam are analyzed. The paper also discusses the implications of these theories on our understanding of mental phenomena, consciousness, and the nature of human experience. (shrink)

This volume presents twelve original essays, by an international team of scholars, on the relation of John Locke's thought to Descartes and to Cartesian philosophers such as Malebranche, Clauberg, and the Port-Royal authors. The essays, preceded by a substantial introduction, cover a large variety of topics from natural philosophy to religion, philosophy of mind and body, metaphysics and epistemology. The volume shows that in Locke's complex relationship to Descartes and Cartesianism, stark opposition and subtle 'family resemblances' are tightly intertwined. (...) Since the turn of the twentieth century, the theory of knowledge has been the main comparative focus. According to an influential historiographical conception, Descartes and Locke form together the spearhead in the 'epistemological turn' of early modern philosophy. In bringing together the contributions to this volume, the editors advocate for a shift of emphasis. A full comparison of Locke's and Descartes's positions should cover not only their theories of knowledge, but also their views on natural philosophy, metaphysics, and religion. Their conflicting claims on issues such as cosmic organization, the qualities and nature of bodies, the substance of the soul, and God's government of the world, are of interest not only in their own right, to take the full measure of Locke's complex relation to Descartes, but also as they allow a better understanding of the continuing epistemological debate between the philosophical heirs of these thinkers.

This paper argues that the substance concept, as discussed by Aristotle in his Categories, aids us to improve our understanding of human nature. Aristotle distinguished the primary from the secondary substance, and substantial from accidental change. We explain these distinctions, their use for understanding phenomena, and discuss how we can integrate them with evolutionary explanations of human nature. For explaining of how the typical human characteristics evolved, we extend our investigations with a discussion of the concept (...) of person. It is argued that psychological attributes, used to characterize persons, are not attributes of a separate mental substance, as Cartesians believe. The concept of a person, though not a substance concept, qualifies a substance concept of a human being possessing rational powers. The latter evolved as the result of language evolution. (shrink)

Two criteria are proposed for characterizing the diverse and not yet perspicuous relations between nanotechnology and nature. They assume a concept of nature as that which is not made by human action. One of the criteria endorses a distinction between natural and artificial objects in nanotechnology; the other allows for a discussion of the potential nanotechnological modification of nature. Insofar as current trends may be taken as indicative of future development, nanotechnology might increasingly use the model (...) of nature as a point of orientation, while many of its products will continue to be clearly distinguished from nature.

The article intends to show the significance of Ch. Peirce’s ideas for the development of contemporary philosophy, to find out the main directions of his criticism of the principles of Cartesian and more broadly modern philosophy (where it comes from Descartes) and to consider the positive program of his philosophy, which he offers as an alternative to Modern philosophy. Peirce starts from a pragmatic and semiotic approach to human nature, consciousness and cognition. Thanks to this approach, he managed (...) to undermine the key ideas of the modern understanding of cognition, human, language, namely: individualism, linguistic atomism, dogmatism, dualism, representationism, nominalism, foundationalism, etc. And, instead, to propose a new theory of knowledge, a new ontology and anthropology. Peirce asserts the indirectness of human cognition by signs (linguistic, cultural, sensory), the impossibility of introspection and intuition, advocates holism, fallibilism, pragmatism, realism, synechism, inferentialism and offers a new understanding of the personality — all this makes him a relevant and contemporary thinker. Peirce’s ideas offer a fresh perspective on modern scientific practice. Peirce’s rethinking of the foundations of knowledge puts him alongside many thinkers of the 20th and 21st centuries. The development of his ideas can be seen in modern anthropology, epistemology, research on artificial intelligence, semiotics, etc. The article is divided into four subsections, which are devoted to the main directions of Peirce’s criticism of Descartes’ philosophy: in the first — against Descartes’ skeptical methodology, Peirce puts the concept of fallibilism and the principle of belief, in the second — Peirce denies the possibility of intuition and proves the indirectness of our cognition by signs, in the third — it is about the advantages of the semiotic and communicative approach over individualism and linguistic atomism, in the fourth — Descartes’ nominalism and dualism, Peirce contrasts the realist approach and his theory of synechism, as well as semiotic anthropology.

From the point of view of the history and philosophy of science, the relationship of Descartes' to Aristotle's concept of nature has not been grasped in an entirely satisfactory way. In this article, the two concepts will be subjected to a comparative analysis, beginning with the outstanding feature that both concepts of nature are characterized by a contradistinction to the non-natural: Aristotle separates nature and technology; Descartes opposes nature to thinking. My thesis is that these (...) meanings have found privileged application in specific contexts of experience: the field of application especially suitable for the Aristotelian concept is the experience of everyday life, while for the Cartesian concept it is subjective experience. Historically, the relationship between meaning and experience is of help in understanding the conditions in which the two concepts arose. The topical relevance of the concepts to modern society is a consequence of the continued existence of the favored contexts of experience. Roughly stated, we sometimes still perceive in an Aristotelian way and at other times think in a Cartesian way. (shrink)

Modern interpreters have often regarded Aristotle’s Posterior Analytics as a mystery, or even a bit of an embarrassment. In his treatises on natural science and ethics, Aristotle is constantly concerned to review the opinions of his predecessors and of people in general; where appropriate, he also takes note of experiential observations, some of them highly specialized. However, the traditional view of the Posterior Analytics is that it advances an almost Cartesian picture of sciences as deductive systems founded on intuitively (...) evident first premises. How are these to be reconciled? (shrink)

Introduction Conatus is a specific concept within Descartes’s physics. In particular, it assumes a crucial importance in the purely mechanistic description of the nature of light – an issue that Des- cartes considered one of the most crucial challenges, and major achievements, of his natural phil- osophy. According to Descartes’s cosmology, the universe – understood as a material continuum in which there is no vacuum – is composed of a number of separate yet interconnected vortices. Each of these (...) vortices consists in a set of bands rotating around their centres. The bands are com- posed of corpuscles of the three elements, each distinguished on the basis of their different shapes and sizes. The small globules of the second element, although impeded by the other parts of heaven, strive to move away from the centre of the vortex around which they revolve, thus exerting a certain force against the surrounding bodies. This striving or conatus, though a mere force rather than a genuine motion, is transmitted instan- taneously and along straight lines from body to body. According to Descartes, then, the nature of light consists in this striving alone. This account must be understood as strictly connected to the fundamental laws that regulate the Cartesian world. It is particularly important to recall that for Descartes the centrifugal force exerted by a rotating body is understood to be a consequence of the intrinsic rectilinearity of every motion. As the second of the three Laws of Nature set forth in Book II of the Principles of Philosophy establishes, “all motion is in itself rectilinear; and hence any body moving in a circle tends to move away from the centre of the circle which it describes as proved by the fact that a stone rotating in a sling tends to move centrifugally along the tangent of each point described by a circle.1 Similarly, each of the globules of the second element “strives to recede with a great force from the centre of the vortex in which it rotates; it is in fact prevented by the other globules placed all around, not differently than a stone in a sling”. Within this framework, as I show later, conatus occurs when a body’s intrinsic tendency to rectilinear motion is impeded by an external constraint. As Stephen Gaukroger notes, the use of the term conatus in the Principles – like “vis” and “ action ” – shows that Descartes “cannot avoid dynamic terminology”, despite his declared intent “to construe motion in a purely kinematic way”. Indeed, Gaukroger observes that the notions of force action and striving are systematically employed in the Principles – appearing 290, 59 and 8 times, respectively. Also noteworthy, conatus was – together with the more familiar concepts of actio and vis – a significant element of the conceptual apparatus of Scholastic natural philosophy. As will be seen later – and this is the first goal of this paper – here the concept of conatus had a very specific function. Indeed, it was a central part of the Aristotelian- Scholastic account of gravitation. Conatus was used to refer to the striving of a body to move towards its natural place – especially in cases where its natural motion was hindered or impeded by an external mover. This specific use of the concept of conatus can be found in texts on natural philosophy from the end of the sixteenth through the late seventeenth century. Notably, it occurs in some of the late -Scho- lastic texts which held special significance for Descartes’s thought. Therefore, Descartes introduces conatus in a context in which this concept already had a very specific meaning, and one of which he was very probably aware. The possible relations between these two apparently very different con- cepts have therefore to be scrutinized. I thereby propose to undertake a comparison between the Scho- lastic and the Cartesian conceptions of conatus. I hope to show that certain traits of the former are indeed echoed by the latter, although adapted to the much changed physical paradigm of Cartesian physics. In fact, Descartes’s conatus, though sharing some important similarities with the old one, underwent significant transformations in terms of both its meaning and its application. However, I hope to show that these concepts are both used to describe the behaviour of bodies in relation to their intrinsic motive tendency, and in particular when this tendency is impeded or prevented. Such a reconstruction offers two main areas of interest. On an immediate level, it furthers the general efforts of scholars over the past decades to reconstruct the full extent of the relations between Descartes’s thought and Scholastic philosophy. However, there is another significant reason for taking an interest in the ties between the Scholastic and the Cartesian conceptions of conatus. Indeed, the Cartesian conatus must be seen as crucial to a proper understanding of the broader, diverse conceptualization that this idea enjoyed in the thought of many of the most important philosophers of the early modern period, namely Spinoza, Hobbes and Leibniz. In particular, Spinoza, were directly influenced by Descartes in their unique formulations of conatus. Thus a reconstruction of the context in which Descartes formulated his conatus and of its relations to a pre-existing Scholastic conception will enable us to better reconstruct the history of this idea in the early modern period. The paper is structured as follows: in the first part, I provide a thorough review of the Scho- lastic employment of the concept conatus – both its meaning and the extent of its usage. I then show that it occurs in some of the most prominent Cartesian sources. Finally, I shall provide an account of Descartes’s theory of circular motion and conatus with the specific aim of empha- sizing the elements of both continuity and discontinuity that justify the claim that Descartes’s con- ception of conatus is reminiscent of the Scholastic one.

Descartes is often identified as having fired one of the opening shots of the scientific revolution: rejecting the four Aristotelian causes in favor of the efficient causes characteristic of mechanistic science. Scholars often write as if Cartesian science and corporeal metaphysics is best understood as a rejection of all causal notions other than the efficient. I argue that this is a mistake. On the contrary, Descartes endorses an avowedly Aristotelian notion of formal causality, inherited from Suárez, and this notion (...) is central to his physics and corporeal metaphysics. -/- I begin by tracing the history of the formal cause from Aristotle to Aquinas and Suárez. My main thesis here is that the Aristotelian notion of formal causation picks out two distinct explanatory modes. The first is linked to hylomorphic ontology, and so by rejecting hylomorphism Descartes rejects one sort of formal causation. Crucially, however, the Aristotelians also identify explanations from essence as a species of formal causality. Now, Descartes’s entire philosophical project is built upon the intellectual perception of the essences of God, mind, and matter; the uncovering and exercise of this broadly Platonic intellectual capacity is, as Descartes explained to Hobbes, a key raison d’être for project of the Meditations. So we might expect Descartes to embrace formal causal explanations from essence, which harmonize so thoroughly with his philosophical project. And indeed, this is what we find. This is most obvious in the case of the ontological argument. In the course of defending the claim that God is causa sui, Descartes explicitly appeals to formal causation and claims to be only be “following in the footsteps” of Aristotle. Thus, there is a Cartesian notion of formal causation that is both continuous with and distinct from its Aristotelian predecessors. -/- Other cases are less obvious, but no less important. For example, one of the most strikingly “modern” aspects of Cartesian physics is its emphasis on quantitative laws. Yet Descartes’s official account of how these laws explain particular phenomena is puzzling: He claims that the laws are causes. This, however, is prima facie absurd; Descartes seems to claim that the law of inertia is literally pushing the moon forward along its orbital path. I argue that this is not and cannot be what Descartes means. On the contrary, he clearly takes the laws of physics to follow from the divine essence, especially immutability and simplicity. The laws are true and epistemically accessible to us because they follow from the divine essence. In other words, Descartes thinks nomological explanation in physics is formal causal explanation from (the divine) essence. -/- Another central issue is the impenetrability, or solidity, of matter. I offer a close reading and reconstruction of Descartes’s argument that matter is necessarily but not essentially impenetrable, and I show how Descartes accounts for impenetrability without compromising his mathematical conception of the corporeal. Descartes argues that impenetrability follows from the nature of matter as geometrical extension, thereby reducing a paradigmatic quality of matter (its solidity) to quantity (extension). Note that the explanatory bite throughout is from essence. Thus, while solidity is not a genuine corporeal causal power, it does give bodies an ineliminable causal role in Cartesian physics and corporeal metaphysics. This role is as a formal cause, since every explanation from impenetrability is ipso facto an explanation from the corporeal essence, geometrical extension. This, in turn, shows that Descartes has a principled response to idealists, like Berkeley, who claim that matter’s lack of efficient causal power implies idealism; Berkeley’s mistake, Descartes would argue, lies in equating efficient causality with causality simpliciter. -/- Thus, I argue that formal causal explanation from essence is both well-attested textually in Descartes and is consonant with some of his deepest projects and commitments, including his Platonic intellectualism and mathematization of the corporeal. All this in mind, it is shocking how little attention has been paid to formal causation in Descartes’s metaphysics. If I am right, a thorough re-thinking of Descartes’s physics and metaphysics is long overdue. (shrink)

This paper explores how, according to three early modern philosophers, philosophical theory should relate to our pre-theoretical picture of reality. Though coming from very different backgrounds, the Spanish scholastic, Domingo de Soto, and the English natural philosopher, Kenelm Digby, agreed that an ability to accommodate our pre-theoretical picture of the world and our ordinary way of speaking about reality is a virtue for a philosophical theory. Yet at the same time, they disagreed on what kind of ontology of the material (...) world is implied by these. The Dutch Cartesian, Johannes de Raey, took a very different approach, and argued that the picture of reality we naturally develop from our early days onwards and the language associated with it have their use in domains such as law and medical practice, but are a poor guide to the ontology of the material world. Thus, if we are to arrive at a proper understanding of the nature of matter, we need to move beyond the picture of reality we naturally develop from our early days onwards in order to come to see that the nature of matter consists in bare extension.

The concept of continuous creation is now widely used in the context of reflections on the dialogue between science and religion. The first part of this research work seeks to understand its meaning through a twofold elaboration: (1) the historical setting of the three philosophical trends in which this concept was developed: scholastic (conservation), Cartesian (conservation through repetition of the creative act at each instant), and dynamic (interpreting the emergence of radical and contingent novelty in nature (...) as a sign of the continuity of creation); (2) a philosophical and theological critique of the concept of continuous creation regarding the question of the relationship between change and creation, in the light of its highly polymorphous contemporary use, and, in opposition, its absence within the Catholic Magisterium. This work opens the field a further step toward reflection on a renewed concept of continuous creation. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Descartes’ Natural Light ReconsideredDeborah Boyle1. INTRODUCTIONThe “natural light” occupies an important position in Descartes’ Third Meditation, where the meditator invokes it to provide the premises needed for his proof for the existence of a non-deceiving God. Descartes also refers to the natural light throughout his Replies to the Objections to the Meditations and in the Principles of Philosophy. Yet he says almost nothing about what the natural light is (...) supposed to be, apparently assuming that his readers already know what he means. English-speaking commentators on Descartes have said little about the natural light,1 and although French commentators have paid slightly more attention to this topic, they have nonetheless provided no detailed analysis of the concept of the natural light and the role it plays in Descartes’ Meditations.2In 1973, however, John Morris published an article entitled “Descartes’ Natural Light” in the Journal of the History of Philosophy, later reprinted in Eternal Truths and the Cartesian Circle.3 Morris argues that “the understanding can be regarded in an active and a passive sense, ”4 and that the natural light should [End Page 601] be equated with the passive function of the intellect. The natural light, he asserts, isa power of cognition, which contrasts with the “active” power of conceiving. Unlike this power, it does not form ideas, or bring them to consciousness. Instead, it simply gives a click of recognition when a true idea is brought before it.5However, the textual evidence for Morris’ interpretation of the natural light is slender, and in fact the texts support a quite different reading. I shall point out some problems with Morris’ reading, and offer the beginnings of an alternative account.2. ACTIVITY, PASSIVITY, AND THE MINDIn the Fourth Meditation, Descartes draws a distinction between two faculties of mind: intellect and will. Intellect, he says, allows him “to perceive the ideas which are subjects for possible judgements” (CSM II 39/AT VII 5),6 while the will “simply consists in our ability to do or not do something (that is, to affirm or deny, to pursue or avoid)” (CSM II 40/AT VII 57). Although he does not say so in the Fourth Meditation, Descartes suggests in two 1641 letters to Regius that the intellect is passive and the will is active; strictly speaking, he says, “understanding [intellectio] is the passivity of the mind and willing [volitio] is its activity” (CSMK III 182/AT III 372). A few months later, he writes that “we should use the term ‘action’ for what plays the role of a moving force, like volition in the mind, while we apply the term ‘passion’ to what plays the role of something moved, like intellection [intellectio] and vision in the same mind” (CSMK III 199/AT III 454–5). And in the Passions of the Soul Descartes states that while volitions are actions, “the various perceptions or modes of knowledge present in us may be called its passions, in a general sense” (CSM I 335/AT XI 342).In his early work, the Rules for the Direction of the Mind, Descartes does refer to “actions of the intellect.”7 If we do not allow for changes in Descartes’ thinking, we might assume that at the time of the Meditations, too, he would be willing to speak of “actions of the intellect.” But Descartes provides no account of the [End Page 602] will in the Rules; thus any activity he might have attributed to the mind would have to be included in the role of the intellect. In the Meditations, Descartes’ philosophy of mind has expanded to provide a place for the will, which can take over the active functions previously assigned to the intellect.John Morris’ reading of the role of the natural light in the Meditations takes as its starting point a passage in the Rules where Descartes claims that the intellect itself, the cognitive power or vis cognoscens, has both active and passive functions; it is, he says, sometimes like a seal, sometimes like wax.8 After describing the various functions of the cognitive power, Descartes concludes that “according to its different functions, then, the same power is...

ABSTRACT:I contrast an ecological account of natural agency with the traditional Cartesian conception using recent research in bacterial cognition and cellular decision making as a test case. I argue that the Cartesian conception—namely, the view that agency presupposes cognition—generates a dilemma between mechanism, the view that bacteria are mere automata, and intellectualism, the view that they exhibit full-blown cognition. Unicellular organisms, however, occupy a middle ground between these two extremes. On the one hand, their capacities and activities are (...) too adaptive to count as mere machines. On the other hand, they lack the open-ended responsiveness of cognitive agents to rational norms. An ecological conception of agency as the gross behavioral capacity to respond to affordances, I argue, does not presuppose cognition and allows for degrees of agency along a continuum, from the simplest adaptive agents, such as unicellular organisms, to the most sophisticated cognitive agents. Bacteria, I conclude, are adaptiveagents, hence not mere automata, but notcognitiveagents. (shrink)

Nine lead papers, all with two or three commentators, and six with replies to the commentators. It is the Identity theorists cum cybernetician versus the "non-Cartesian dualists" and C. D. Broad-style interactionists. The most sparks are generated with MacKay's paper, "From Mechanism to Mind," and the ensuing exchange between MacKay and Beloff; MacKay's paper is intended as a summary of his work in cybernetics as it relates to the philosophy of mind, and Beloff's criticisms range from the cautious to (...) the devastating. Beloff's own paper is a well-ordered, rear-guard action against the Identity theory, which fastens on the dual nature of consciousness and para-psychological phenomena as the theory's present obstacles. Flew's "A Rational Animal" is an incisive challenging of what he dubs the "Co-existence Thesis," i.e., the view defended by such people as Winch and MacIntyre, that explanations by reasons and explanations by causes, or, in another idiom, teleological and mechanical explanations, can exist together in irreducible harmony—even given the ideal of a unified science. It should be mentioned that Price's paper is the bulk of his 1952 lecture before the Members of the Society for Psychical Research, "Survival and the Idea of 'Another World.'"—E. A. R. (shrink)

Some consequences of direct realism and William James’s philosophy of mind are considered in terms of American naturalism as seen in the debate between John Dewey and Roy Wood Sellars. Sellars’s critical realism and evolutionary naturalism is compared and contrasted with Dewey’s pragmatic realism and emphatically evolutionary naturalism. Though these naturalisms are similar, there are significant differences between methodology, their critiques of James’s reflex arc concept in his Principles of Psychology, and the mind-body problem. Sellars’s critical realism and naturalism (...) retains a priori commitments to fixed categories and concepts, whereas Dewey’s emphatically evolutionary pragmatic naturalism is empirical and sees continuities where Sellars insists on discontinuities. One significant difference is Sellars’s maintaining a place for introspection as methodologically appropriate and Dewey’s’ rejection of it. These differences are illustrated through Sellars’s modification of the reflex arc to include an organic but interpretative step, and Dewey’s radical criticism of approaches like James’s and Sellars’s as recapitulating the Cartesian dualism that such views intended to overcome. These differences are finally contrasted in Sellars’s maintaining a privacy of mind by constraining it to the brain in a dual-aspect theory, while Dewey advocates mind as sociocultural, expanding mind into body and world.

The notion of a natural numbers object in a monoidal category is defined and it is shown that the theory of primitive recursive functions can be developed. This is done by considering the category of cocommutative comonoids which is cartesian, and where the theory of natural numbers objects is well developed. A number of examples illustrate the usefulness of the concept.

The claim that Descartes could have derived the certainty of his existence from the infallibility of the self?referential use of T is rejected because it fails to take account of the hyperbolical hypothesis. Recognizing the constraints which the latter involved, Descartes tried to secure Sum by an argument in modus ponens, which requires an incorrigible statement about experience as a minor premiss. Because he had an incorrect conception of the nature of statements, Descartes failed to realize that the circumstances (...) described in the hypothesis exclude the conditions necessary for any statements or thoughts whatsoever. This, in turn, led to a systematic conflation of statements with sentences. The incoherence of the argument follows from the fact that Cogito could at best be a sentence and not a statement and, as such, could not provide the required minor premiss. It is a further consequence of Descartes's conflation of statements with sentences that the subject of the hypothesis cannot be identical with the subject responsible for the hypothesis and that Descartes's hypothesis cannot therefore be about himself.

Collected here are the written traces of courses on the concept of nature given by Maurice Merleau-Ponty at the Collège de France in the 1950s-notes that provide a window on the thinking of one of the most influential philosophers of the twentieth century. In two courses distilled by a student and in a third composed of Merleau-Ponty's own notes, the ideas that animated the philosopher's lectures and that informed his later publications emerge in an early, fluid form in (...) the process of being elaborated, negotiated, critiqued, and reconsidered. Merleau-Ponty's project in these courses is an interrogation of nature, a task at the center of his investigation of perception, truth, and subjectivity. The first course, a survey of the historical elements in our concept of nature, examines first the Cartesian concept of nature and then historical and contemporary responses to Descartes, all with an eye toward developing a vision of nature more consistent with the findings of contemporary science. In the second course, Merleau-Ponty takes up the problem of the relation of nature to ontology in general. Here, the key question is how the animal finds itself in its world. Because the human body is ultimately "an animal of movements and perceptions," humanity is intertwined with animality. In the third course, "Nature and Logos: The Human Body," Merleau-Ponty assesses his previous findings and examines the emergence of the human body at the intersection of nature and Logos. This course, contemporaneous with the working notes for The Visible and the Invisible, allows us to observe the evolution of that work as well as to revisit the research he had begun in Primacy of Perception. In these traces: a new reading of Descartes; a measured appreciation of Schelling; an assessment of recent developments in the sciences that leads to the notion of the body as a "system of equivalencies"; and an examination of the phenomenon of life. We have a wealth of material that allows us to reconsider Merleau-Ponty's thinking and to engage his philosophical project anew. Before his death in 1961, Maurice Merleau-Ponty was chair in philosophy at the Collège de France. Robert Vallier is completing his doctoral work on Merleau-Ponty and Schelling at DePaul University. He has also taught at the Universite de Paris-X and at the College Internationale de Philosophie. (shrink)

The paper shows how Bohmian mechanics fits into modern science as conceived by Descartes. The primitive ontology of particle positions only vindicates the Cartesian conception of matter as res extensa also in the domain of quantum physics. Finally, I briefly sketch out how Bohmian mechanics can also be construed as respecting the limits that Descartes set for modern science: there is no conflict between the ontology and dynamics of matter as set out in Bohmian mechanics and a Cartesian (...) stance that takes the mind to be irreducible to matter.

The conception of a ‘law of nature’ is a human product. It was created to play a role in natural philosophy, in the Cartesian tradition. In light of this, philosophers and scientists must sort out what they mean by a law of nature before evaluating rival theories and approaches. If one’s conception of the laws of nature is yoked to metaphysical notions of truth and explanation, that connection must be made explicit and defended. If, on the (...) other hand, one’s aim is to disentangle laws from truth or from explanation, that must be stated and defended as well. If philosophers do not make such assumptions, intuitions, and methodological commitments clear, then it will be impossible to identify the source of disagreement in debates about the laws of nature. Are the conflicts rooted in disagreement about the conclusions reached, or do the background commitments of the combatants block any resolution to the dispute in principle or in practice? (shrink)
