The Knowability Paradox is a logical argument that, starting from the plainly innocent assumption that every true proposition is knowable, reaches the strong conclusion that every true proposition is known; i.e. if there are unknown truths, there are unknowable truths. The paradox has been considered a problem for every theory assuming the Knowability Principle, according to which all truths are knowable and, in particular, for semantic anti-realist theories. A well known criticism to the Knowability Paradox is the so (...) called restriction strategy. It bounds the scope of the universal quantification in (KP) to a set of formulas whose logical form avoids the paradoxical conclusion. Specifically, Tennant suggests to restrict the quantifier in (KP) to propositions whose knowledge is provably inconsistent. He calls them Anti-Cartesian propositions and distinguished them in three kinds. In this paper we will not be concerned with the soundness of the restriction proposal and the criticisms it has received. Rather, we are interested in analyzing the proposed distinction. We argue that Tennant’s distinction is problematic because it is not completely clear, it is not grounded on an adequate logical analysis, and it is incomplete. We suggest an alternative distinction, and we give some reasons for accepting it: it results logically grounded and more complete than Tennant’s one, inclusive of it and independent from non-epistemic notions.

Rene Descartes's argument begins from one obviously true premise that (at the time when he was considering this argument) Descartes is thinking. It then proceeds by means of two principles about what is “conceivable” to the conclusion that Descartes is essentially “a thinking substance distinct from his body, which he calls his 'soul'”. This chapter looks in more detail at Descartes's argument. It explains some of the terminology which Descartes uses. Descartes consists of two parts ‐ an essential part (his (...) soul) and an inessential part (his body). And, Descartes would add, what applies to Descartes, applies to all other humans. Hence substance dualism ‐ humans consist of two substances, a soul (the essential part) and a body (the inessential part). The chapter illustrates how there can be Descartes's propositions whose metaphysical modality differs from their logical modality. (shrink)

In this paper, I provide what I believe to be Descartes's own solution to the problem of the Cartesian Circle. As I argue, Descartes thinks he can have certain knowledge of the premises of the Third Meditation proof of God's existence and veracity (i.e., the 3M-Proof) without presupposing God's existence. The key, as Broughton (1984) once argued, is that the premises of the 3M-Proof are knowable by the natural light. The major objection to this "natural light" gambit is that (...) Descartes identifies the natural light with the faculty of clear and distinct perception, a faculty that cannot be known to be reliable in advance of the 3M-Proof. I explain that Descartes distinguishes between three kinds of clear and distinction perceptions depending on their source; the senses, the imagination, or the intellect. I claim that although the First Meditation is designed to cast doubt on the clear and distinct perceptions of the senses and of the imagination, it is not designed to cast doubt on the clear and distinct perceptions of the intellect. The "natural light" gambit relies on the assumption that the natural light, by which propositions can be certainly known without presupposing knowledge of God's existence, is to be identified with the faculty of *intellectual* clear and distinct perception.

The Cartesian skeptic’s strategy is to tell a story about the world that is entirely consistent with all of the empirical evidence that we do, or can, have, but according to which many or all of our ordinary beliefs are false. He then suggests that, since we cannot show that his story is false, we ought to surrender those beliefs. In this paper I offer a decision-theoretic response to skepticism. Say that a cognitive attitude is a propositional attitude that (...) may be true or false. I argue that rejecting the skeptic’s story, and so retaining our ordinary opinions, will yield for us true cognitive attitudes, no matter whether the skeptic’s story is true or false, and that the best any alternative can do is yield no cognitive attitudes at all. Hence, it is rational to retain our ordinary opinions. One may be concerned that I can maintain this surprising conclusion because the cognitive attitudes at issue are not real beliefs, and do not represent the real world. I conclude the paper by arguing that this concern is misplaced. (shrink)

Perhaps the most influential compatibilist response to this question is Fodor's strategy of levels. Fodor argues that although psychological laws range over world-involving propositional attitudes and their contents, these laws are implemented in computational mechanisms that supervene on the individual's intrinsic states.

Based on the distinction drawn by James Conant between Cartesian skepticism and Kantian skepticism, I intend to show that Wittgenstein’s remarks on dreaming should not be understood as a direct attack on the former, as commonly held, but as an indirect attack on it, for Wittgenstein approaches Descartes’ dreaming hypothesis by changing the very problematic at stake. Wittgenstein’s attack on skepticism takes one step back from a question about how to distinguish between dreaming that one is experiencing something and (...) actually experiencing it, for this attack focuses on the linguistic conditions of the possibility of something that the Cartesian problematic takes for granted, that is, the very possibility of saying “I am dreaming.” I also intend to show that Wittgenstein’s remarks on dreaming should be read in light of his claim that skepticism is nonsensical put forward in the Tractatus logico-philosophicus as well in his last writings. More specifically, I intend to show that the words “I am dreaming” are nonsensical in the same sense as the alleged proposition “There are physical objects” and the expression of doubt about the existence of physical objects or the external world.

The objective of the article is twofold: to advance an interpretation of Descartes’ position on the problem of explaining how deduction from universal propositions to their particular instances can be both legitimate and useful for discovery of truth; and to argue that his position is a valuable contribution to the philosophy of logic. In Descartes’ view. the problem in question is that syllogistic deductions from universal propositions to their particular instances is circular and hence useless as a means for discovery (...) of truth. Descartes’ solution to the problem is to claim that noncircular, useful deduction from the universal to the particular must first be based on deduction from particular truths to particular truths. I examine previous interpretations of Cartesian deduction given by E.M. Curley, Bernard Williams, and Andre Gombay. None of these interpretations fit with all of Descartes’ criticisms of syllogistic deduction and his characterization of useful and legitimate deduction (such as the cogito). I argue that the key to a correct interpretation is Descartes’ claim that implicit knowledge of universal propositions plays a crucial role in useful and legitimate deduction, and I explain how we may cash in his talk of implicit knowledge through Ryle’s notion of knowing how. Having set out a fuller explication of Descartes’ theory of deduction, I argue that it is consistent with the way people actually reason, that it helps us with problems in the philosophy of logic that have been raised by John Stuart Mill, Hilary Putnam, and Michael Dummett.

Locke tells us that his purpose in An Essay Concerning Human Understanding is “to inquire into the original, certainty, and extent of human knowledge, together with the grounds and degrees of belief, opinion, and assent”. He provides a characterization of general human knowledge as universal truths in propositional form. In doing this he presupposes a striking doctrine about the “extent” of man's general knowledge, and he draws freely upon a theory meant to explain both the materials out of which this (...) knowledge is constructed and the way in which it is constructed. He holds that the “certainty” which characterizes general knowledge is obtained only if we proceed from the right materials or foundations in the right way, and that the right foundations themselves can only be obtained in one specific way. In this study I try to show how much more Cartesian Locke is than many commentators would allow. I argue that on Locke's own view the way to obtain the foundations for general knowledge is that of Cartesian analysis, and the way to construct general knowledge once these foundations have been obtained is that of Cartesian synthesis.

Jennifer Windt’s Dreaming is an enormously rich and thorough book, developing illuminating connections between dreaming, the methodology of psychology, and various philosophical subfields. I’ll focus on two epistemological threads that run through the book. The first has to do with the status of certain assumptions about dreams. Windt argues that the assumptions that dreams involve experiences, and that dream reports are reliable — are methodologically necessary default assumptions, akin to Wittgensteinian hinge propositions. I’ll suggest that Windt is quietly pre-supposing some (...) sceptical assumptions, and that recent literature in epistemic externalism may bear in important ways on her arguments. The second thread involves the perennial sceptical worry that dreaming threatens ordinary knowledge. I’ll suggest again that Windt makes tacit sceptical assumptions one may wish to resist. (shrink)

At the beginning of Meditation Three, Descartes puts forward the proposition that whatever he clearly and distinctly perceives is true. He observes, however, that so long as he does not know whether there is a deceiving God, he has reason to doubt the proposition. Later in Meditation Three, he purports to prove that there is no deceiving God. The difficulty, as Arnauld pointed out, is to see how Descartes avoids reasoning in a circle or begging the question here, (...) for if he can be certain that there is no deceiving God only because he clearly and distinctly perceives this, then he must already be certain that what he clearly and distinctly perceives is true. (shrink)

In this article the questions under discussion are the properties of Descartes’s application of the first rule of his method, which requires not to agree with anything that could give rise to doubt. It is well known that Descartes came to the conclusion that only the truth “I think, therefore I am” is undoubted. The article examines the logical status of this truth and reveals that it is an entimeme where the major premise is unstated. An analysis of Descartes’s works (...) shows that the premise that he does not explicitly express is the proposition “If I think, therefore I exist, and if I do not think, then I do not exist.” It follows that Descartes’ complete syllogism would be like this: “I exist if and only if I think; I think; therefore, I exist.” In this paper, the discussion focuses on the proof of the certainty of the position “I exist,” proposed by St Augustin in his treatise The City of God. St Augustin proves the proposition “I am deceived that I exist” to be false in every possible interpretation. Hence the position “I exist” is true in every possible interpretation. According to Descartes, the only undoubted statements are those that are kept within the limits of “I think,” or within the limits of inner experience, while the data of external experience are always dubious. Thus, the statement “I walk” is not obvious, since it can only seem to me that I am walking. At the same time, the judgment “It seems to me that I walk” is undoubtedly. Ancient sceptics also believed that the data of internal experience are doubtless, and the data of external experience are not due to the fact that all objects of the external world are in fact not what they seem to be. However, there is a significant difference between the ancient sceptical approach and that of Descartes. I put forward the view that the ancient sceptics, although they are convinced that the things of the external world are not what they seem, still surely believe that each item in that world exists. But Descartes surpassed both ancient sceptics and academics in their scepticism, since he doubted the very existence of the external world. He was able to imagine that he exists exclusively as a thinking entity with no body, no world around him, and no space to store that world. It is by the fact that Descartes doubts the existence of the external world that he has cleared the way for transcendental philosophy and phenomenology. (shrink)

Image factorizations in regular categories are stable under pullbacks, so they model a natural modal operator in dependent type theory. This unary type constructor [A] has turned up previously in a syntactic form as a way of erasing computational content, and formalizing a notion of proof irrelevance. Indeed, semantically, the notion of a support is sometimes used as surrogate proposition asserting inhabitation of an indexed family. We give rules for bracket types in dependent type theory and provide complete semantics (...) using regular categories. We show that dependent type theory with the unit type, strong extensional equality types, strong dependent sums, and bracket types is the internal type theory of regular categories, in the same way that the usual dependent type theory with dependent sums and products is the internal type theory of locally Cartesian closed categories. We also show how to interpret first-order logic in type theory with brackets, and we make use of the translation to compare type theory with logic. Specifically, we show that the propositions-as-types interpretation is complete with respect to a certain fragment of intuitionistic first-order logic, in the sense that a formula from the fragment is derivable in intuitionistic first-order logic if, and only if, its interpretation in dependent type theory is inhabited. As a consequence, a modified double-negation translation into type theory (without bracket types) is complete, in the same sense, for all of classical first-order logic. (shrink)

According to many critics, Descartes argued in a circle when he presumed to base the certainty (and thus knowledge) of propositions that fulfill his epistemic criterion of being “clearly and distinctly perceived” on the demonstration that God exists and is not a deceiver. But his critics say, that demonstration, as he presented it, presupposed the validity of the same epistemic criterion. I critically examine two major strategies to dispel the appearance of circularity, two ways of interpreting Descartes’ argument.My approach shares (...) with the second strategy the contention that Descartes did adopt the principle that “whatever is clearly and distinctly perceived to be true is true,” prior to his consideration of the God question. Moreover, his demonstration of God’s existence and veracity made use of the principle. But my claim is that the knowledge of God’s existence and veracity is not used to validate the principle of clear and distinct perception (that would be unnecessary). It is used rather to defeat the sceptic’s argument that we cannot have any knowledge of the external, physical world. I proceed to present and explain Descartes’ argument centered around the thesis, “I cannot be certain that (r) any of my representational ideas of the external world are veridical, unless I am certain that (q), God exists and is not a deceiver.” That is, I prove why, for Descartes, (q) is necessary for (r). My discussion exposes some new facets to the principle of clear and distinct perception and reveals the fact that some familiar Cartesian distinctions that were not thought to be relevant to the problem of the Cartesian Circle are crucial to the solution of that problem.

René Descartes, one of the dominant figures in the history of philosophy, has been accused of one of the most obvious mistakes in the history of philosophy — the so-called cartesian circle. It is my goal in this paper to arrive at an understanding of Descartes's work that attributes to him a theory that should be of philosophical interest to contemporary epistemologists, is consistent with, and suggested by, the actual text, and avoids the circle.I begin with a brief explanation (...) of the supposed circle. In his search for absolute certainty Descartes requires that in order for a proposition to be an instance of knowledge it must be indubitable for the knower, and in order for it to be indubitable for the knower she must be able to eliminate any possibility of the belief's being false. It is to provide a means to satisfy this requirement that Descartes proposes the principle whatever is clearly and distinctly perceived cannot be false.And it seems that Descartes's defense of CD traps him in the circle.

I consider two events in late seventeenth-century philosophy: the condemnation of Cartesianism by the church, the throne, and the university and the noncondemnation of Gassendism by the same powers. What is striking about the two events is that both Cartesians and Gassendists accepted the same proposition deemed heretical. Thus, what was sufficient to condemn Cartesianism was not sufficient to condemn Gassendism. As a result, I suggest that to understand what is involved in condemnation one has to pay close attention (...) to the intellectual and/or social context and to rhetorical strategy, not just to the propositions condemned. In this case, what is at stake are some of the central propositions of corpuscularianism and the mechanical philosophy. (shrink)

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)

In lieu of an abstract, here is a brief excerpt of the content:Toward a Non-Cartesian Psychotherapeutic Framework: Radical Pragmatism as an AlternativeLouis S. Berger (bio)AbstractPostmodern criticism has identified important impoverishments that necessarily follow from the use of Cartesian frameworks. This criticism is reviewed and its implications for psychotherapy are explored in a psychoanalytic context. The ubiquitous presence of Cartesianism (equivalently, representationism) in psychoanalytic frameworks—even in some that are considered postmodern—is demonstrated and criticized. The postmodern convergence on praxis as (...) a desirable alternative to Cartesianism is reported, and its relevance for psychoanalysis is considered. The severe conceptual difficulties entailed in formulating such an alternative are discussed, as are those difficulties that would be encountered were psychoanalysis to attempt the shift from explanatory mental science to praxis. The principal psychoanalytic problematics explored are: the paradoxical relationships between theory and therapeutic technique; the therapeutic action; and validation of clinical practices. Initial, nontraditional suggestions for addressing these problems are offered.Keywordspsychoanalysis, therapeutic action, representation, state space, praxis, hermeneutics, Descartes, Heidegger, Wittgenstein“But the inability to bring one’s subject under conceptual control, fixing it propositionally, is not the end of thinking; on the contrary, it were better to say that the breakdown of concepts and the failure of words is an opening that takes us out of the realm where representation and calculation are all that matter to thinking.... [T]his is what happens in the Socratic dialogue where the negativity in which one ends up at a loss for words is at the same time that which sets thinking free.”Bruns 1989, 9“To evolve theory as though our methods and processes of study were essentially the same, or could be the same, as those of other sciences, or could be disregarded when it comes to theory, implies a view of reality that is no longer tenable, least of all in that ambiguous area which we call psychic reality. Nevertheless, all of us are still more or less captives of an erroneous understanding of objectivity and objective reality....”Loewald 1970, 45 [End Page 169]CartesianismCartesianism still underlies and dominates much of today’s thought. It is the label for a network of interrelated ideas and themes:the ontological duality of mind and body; the subjective individualism implicit in the ultimate appeal to direct personal verification; the method of universal doubt which was supposed to lead us to indubitable truths; the doctrine that language and signs are an external disguise for thought; the doctrine that vagueness is unreal and that the philosophic endeavor is one of knowing clearly and distinctly a completely determinate reality; and most fundamentally, the doctrine that we can break out of the miasma of our language or system of signs and have direct intuitive knowledge of objects. (Bernstein 1971, 5–6)[The Cartesian assumptions] constitute a picture of science and the world somewhat as follows: there is an external world which can in principle be exhaustively described in scientific language. The scientist, as both observer and language-user, can capture the external facts of the world in propositions that are true if they correspond to the facts and false if they do not. Science is ideally a linguistic system in which true propositions are in one-to-one relation to facts, including facts that are not directly observed because they involve hidden entities or properties, or past events or far distant events. These hidden events are described in theories, and theories can be inferred from observation, that is, the hidden explanatory mechanism of the world can be discovered from what is open to observation. Man as scientist is regarded as standing apart from the world and able to experiment and theorize about it objectively and dispassionately.(Hesse 1980, vii)Hesse goes on to say that “almost every assumption underlying this account has been subjected to damaging criticism,” a view echoed by others: “Most contemporary philosophers have been in revolt against the Cartesian framework” (Bernstein 1971, 5); “A rejection of the Cartesian view is a central theme for both of the giants of twentieth-century philosophy, Heidegger and Wittgenstein” (Sass 1992, 444n 77); and “The notion of alternative conceptual frameworks has been a commonplace of our culture since Hegel” (Rorty 1982, 3).These criticisms arise...

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)

Il se peut du point de vue des etudiants qui s'approchent de la position contextuelle de Descartes, qu'il accepte la distinction reelle entre l'esprit et le corps parce qu'il n'a pas percu comment une forme d'explicarion mecanique-materialiste pourrait etre appropriee aux phenomenes psychologiques. Mais on pourrait demander la signification de cette proposition en ce qui concerne le raisonnement de Descartes pour Pactualite du dualisme. Je demontre que son raisonnement dans les Meditations est defectueux relatif a un probleme theorique emanant (...) de 1' argumentation du cogito. Sum est deduit de cogito. Si c'est le cas, pourquoi Descartes pretend-t-il que celui-la est la premiere certitude?

Last year, as some of you may recall, I took it upon my chairly shoulders to solve the problem of causation, where this problem can be stated this way: What is causation? According to the analysis I offered, C is a cause of E if and only if C makes E happen. I am happy to report that, in the year since delivering this account of causation, no objections have arisen. The critics have been silenced. Indeed, my colleague Dan Hausman, (...) the Herbert Simon Professor of Philosophy, reports that he is no longer satisfied with the view he expressed in his recent book on causation, and I have no doubt that his change of mind is due in no small part to my seminal contribution to this subject. If you would permit me a joke, I think I “made happen” a change in Dan’s mind. I should also mention that we are now fortunate to have amongst us Carolina Sartorio, whose own analysis of causation, arrived at independently, seems but a stylistic variant of my own. Where I see causes as things that make things happen, she sees them as things that make a difference. I think, but can’t be certain, that our analyses come to the same thing. Perhaps if she hadn’t muddied the waters with all those numbered propositions and ‘ifs’ and ‘thens’ we could settle the matter. (shrink)

Kant was the first great anti-Cartesian in epistemology and philosophy of mind. He criticised five central tenets of Cartesianism and developed sophisticated alternatives to them. His transcendental analysis of the necessary a priori conditions for the very possibility of self-conscious human experience invokes externalism about justification and proves externalism about mental content. Semantic concern with the unity of the proposition—required for propositionally structured awareness and self-awareness—is central to Kant’s account of the unity of any cognitive judgment. The perceptual (...) ‘binding problem’ is central to Kant’s account of the unity of the object in perception. This paper outlines Kant’s development and justification of his a rationalist account of our active intellect and its roles in perceptual consciousness and in rational judgment, including our consciousness of our rational freedom, all through a radically innovative transcendental inquiry into the necessary a priori conditions for us to be conscious at all. Kant’s anti-Cartesianism is a major philosophical breakthrough far surpassing contemporary anti-Cartesian efforts. It behoves us to give Kant his due and avail ourselves of his profound insights into the nature of human mindedness. (shrink)

In his influential paper ‘Two Types of Foundationalism,’ William Alston distinguishes two important conceptions of foundationalism: ‘simple foundationalism’ and ‘iterative foundationalism’. SF is the view that there are immediately justified beliefs of some kind or other. IF is the stronger view that certain epistemic propositions are immediately justified. Alston favors a reliability account of immediate justification of the kind defended by externalists such as Armstrong, Dretske, and Goldman. Alston rejects IF by appeal to what he calls the ‘second level argument.’ (...) He claims, further, that since IF is essential to the Cartesian project of reconstructing knowledge, the Cartesian project must be abandoned. (shrink)

Any study of the 'Scientific Revolution' and particularly Descartes' role in the debates surrounding the conception of nature (atoms and the void v. plenum theory, the role of mathematics and experiment in natural knowledge, the status and derivation of the laws of nature, the eternality and necessity of eternal truths, etc.) should be placed in the philosophical, scientific, theological, and sociological context of its time. Seventeenth-century debates concerning the nature of the eternal truths such as '2 + 2 = 4' (...) or the law of inertia turn on the question of whether these truths were created along with nature, or were uncreated and subsisting in God's mind. One's answer to that question has direct consequences for conceptions of the necessity/contingency of mathematical and natural knowledge, how knowledge of such truths is accomplished by humans, and what grounds these truths. In this paper, I review the positions of four successors to Descartes' philosophy on the question of the eternal truths to illustrate how in specific ways that question with its theological, metaphysical, modal, and epistemological dimensions concerned the objectivity and certainty of the discoveries of the new science.

I require students to post a short paragraph in response to the question or some posting by a classmate on the question. Students are required to post by 10 a.m. the day before we meet for class on a course website. Week 1: According to Descartes, what role does skepticism play in scientific reasoning? Week 2: Comment on the following: 'But I am supposing this machine to be made by the hands of God, and so I think you may reasonably think it capable of a greater variety of movements than I could possibly imagine in it, and of exhibiting more artistry than I could possibly ascribe to it' [ Treatise on Man ; ATXI 120]. Week 3: What is Descartes' conception of the relation between the metaphysics and physics of nature? Week 4: Critically discuss the positions of Descartes, Malebranche, and Leibniz on what provides the foundation for the certitude of natural knowledge? Week 5: Explain why both Malebranche and Leibniz consider moral sin to be analogous to natural defect? Seminar/Project Idea Hold a debate on the question of the status of the eternal truths. The proposition will be Descartes' position: 'Eternal truths must be both created and necessary if certainty in science is to be possible'. Format: 1. At the beginning of the 5-week module, students will be assigned to one of three roles: Team A, Team B, and judge's panel. Students will be given the debate proposition, but will not be told which team will take the affirmative and which team the negative until the time of the debate. 2. Recommend a variation on the Classic Debate Format to encourage the development of argument: sequence begins with affirmative construction (8 minutes), negative construction (8 minutes), second affirmative construction (8 minutes), second negative construction (8 minutes), first negative rebuttal (4 minutes), first affirmative rebuttal (4 minutes), final negative rebuttal (4 minutes) and final affirmative rebuttal (4 minutes). 3. Judges Panel: will consist of 3–4 judges who will assess the performance of Teams A and B. Judgment should be based on the persuasiveness of the team position. 4. Debate will be held at the end of the fifth week, or semester, whichever makes most sense given the course length and structure. Acknowledgements The author gratefully acknowledges the immensely helpful comments and suggestions by the participants in her graduate seminar on the Scientific Revolution: Benjamin Chicka, Sarah Jacques-Ross, Richard Ross, Marcella Stockstill, and Zohra Wolters.

This is a reply to Timothy Williamson ’s paper ‘Tennant’s Troubles’. It defends against Williamson ’s objections the anti-realist’s knowability principle based on the author’s ‘local’ restriction strategy involving Cartesian propositions, set out in The Taming of the True. Williamson ’s purported Fitchian reductio, involving the unknown number of books on his table, is analyzed in detail and shown to be fallacious. Williamson ’s attempt to cause problems for the anti-realist by means of a supposed rigid designator generates a (...) contradiction with arithmetic right away, upon instantiating the obviously relevant theorem that every natural number is provably odd or provably even. The paper also explains and formulates a globally restricted knowability principle, which likewise blocks the attempted reductio. (shrink)

O trabalho pretende mostrar como a filosofia da idéia de infinito em Levinas se articula com a concepção da temporalidade diacrônica. A referência filosófica mais explícita e recorrente da idéia de infinito em Levinas é o pensamento cartesiano da Terceira Meditação, porém outras influências muito relevantes para este tema provêm dos textos talmúdicos. Procuramos aproximar as duas fontes do pensamento levinasiano, filosofia e judaísmo, pela análise de dois conceitos fundamentais da obra de Levinas, infinito e temporalidade. PALAVRAS-CHAVE – Infinito. Temporalidade. (...) Ética. ABSTRACT The article seeks to show how the philosophy of the idea of infinite in Levinas is articuled with the conception of diachronic temporality. The more explicit and recurrent philosophical reference of the idea of infinity in Levinas’s thinking is the Cartesian proposition of the Third Meditation; however, other very important influences concerning this theme come from the Talmudic Lectures. We try to approximate the two sources of the Levinasian thinking through the analysis of two fundamental concepts of his work, infinity and temporality. KEY WORDS – Infinity. Temporality. Ethics.

This paper aims to restore, from the political thought of Merleau-Ponty, the rightful place of conflict. To achieve this hypothetical premise it is necessary to consider some issues that are woven into possible readings of the origin or foundation of politics. First, tracing back to the original cartesian proposition that the body is related with extensive substance invalid when detecting who we are. Then, considering the reading Merleau-Ponty makes of Machiavelli considering the notion of riot or mass under (...) a conflicting structure of politics in relation to the subject. In this regard, it is noted from this reading, the conditions proposed by Merleau-Ponty to highlight the importance of the singular in a politically shared space. And finally, to understand these problem areas of the history of philosophy as their own "world of life" where the contingent has a particular sense understood as the ontological place of the practical subject. Thus, in this context, it is possible to reconcile from Merleau-Ponty in the area of the contingent, body and language; what is felt and thought; perceived and settled. To understand the features of sedimentation helps to the formation of the localized subject; that is, it habituated or instituted. (shrink)

The paper is the final, fifth part of a series of studies introducing the new conceptions of “Hilbert mathematics” and “ontomathematics”. The specific subject of the present investigation is the proper philosophical sense of both, including philosophy of mathematics and philosophy of physics not less than the traditional “first philosophy” (as far as ontomathematics is a conservative generalization of ontology as well as of Heidegger’s “fundamental ontology” though in a sense) and history of philosophy (deepening Heidegger’s destruction of it from (...) the pre-Socratics to the Pythagoreans). Husserl’s phenomenology and Heidegger’s derivative “fundamental ontology” as well as his later doctrine after the “turn” are the starting point of the research as established and well known approaches relative to the newly introduced conception of ontomathematics, even more so that Husserl himself started criticizing his “Philosophy of arithmetic” as too naturalistic and psychological turning to “Logical investigations” and the foundations of phenomenology. Heidegger’s “Aletheia” is also interpreted ontomathematically: as a relation of locality and nonlocality, respectively as a motion from nonlocality to locality if both are physically considered. Aristotle’s ontological revision of Plato’s doctrine is “destructed” further from the pre-Socratics' “Logos” or Heideger’s “Language” (after the “turn”) to the Pythagoreans “Numbers” or “Arithmetics” as an inherent and fundamental philosophical doctrine. Then, a leap to contemporary physics elucidates the essence of ontomathematics overcoming the Cartesian abyss inherited from Plato’s opposition of “ideas” versus “things”, and now unifying physics and mathematics, particularly allowing for the “creation from nothing” instead of the quasi-scientific myth of the “Big Bang”. Furthermore, ontomathematics needs another interpretation of arithmetic, propositional logic and set theory in the foundations of mathematics, where the latter two ones are both identified with Boolean algebra, and the former is considered to be a “half of Boolean algebra” in the exact meaning to be equated to it after doubling by a dual anti-isometric counterpart of Peano arithmetic. That unified algebraic realization of the foundations of mathematics is related to Hilbert mathematics in both “narrow and wide senses” where the latter is isomorphic to the qubit Hilbert space, thus underlying all the physical world by the newly introduced substance of quantum information being physically dimensionless and generalizing classical information measured in bits. The substance of information, whether classical or quantum, visualizes the way of the unification of physics and mathematics by merging their foundations in Hilbert arithmetic and Hilbert mathematics: thus how ontomathetics is a “first philosophy”. The relation of ontomathematics to the Socratic “human problematics”, furthermore being fundamental for Western philosophy in Modernity, is discussed. Ontomathematics implies its “substitution” by abstract information (or by “subjectless choice” relevant to it), thus “obliterating the human outline on the ocean beach sand” (by Michel Foucault’s metaphor). A reflection back from the viewpoint of mathematic to Western philosophy as the philosophy of locality ends the study. (shrink)

Bart Streumer thinks that we cannot believe the global normative error theory. Streumer's argument presupposes a Cartesian theory of belief fixation. The Cartesian theory entails that we can understand a proposition without believing it. But the Cartesian theory of belief fixation is false, and the Spinozan theory is true. The Spinozan theory of belief fixation entails that we cannot understand a proposition without believing it. The present paper argues that Streumer's claim is false, and we (...) can believe the global normative error theory because the Spinozan theory is correct. The paper then applies the Spinozan theory of belief fixation to the “Now what?” problem for global normative error theory and responds to objections. (shrink)

Although pragmatism and phenomenology have both contributed significantly to the genealogy of so-called “4E” – embodied, embedded, enactive and extended – cognition, there is benefit to be had from a systematic comparative study of these roots. As existing 4E cognition literature has tended to emphasise one or the other tradition, issues remain to be addressed concerning their commonalities – and possible incompatibilities. We begin by exploring pragmatism and phenomenology’s shared focus on contesting intellectualism, and its key assumption of mindedness as (...) representation. We then outline distinctive insights from both traditions regarding the nature and role of habits, in order to put forward a habit-based epistemology as an alternative to the Cartesian idea-based epistemology that has dominated modern philosophy. We pay particular attention to the work of classical pragmatist C.S. Peirce, arguing that his semiotics, which analyses sign-use as habit, shows how theorists of embodied cognition can break a certain false dichotomy between embodiment and logical or intellectual structure which has prevented them from fully theorising propositional knowledge. In this way, our work both augments and challenges the Dewey/Merleau-Ponty connection that has been much more extensively explored by the field. (shrink)

Cartesian scepticism poses the question of how we can justify our belief that other humans experience consciousness in the same way that we do. Wittgenstein’s response to this scepticism is one that does not seek to resolve the problem by providing a sound argument against the Cartesian sceptic. Rather, he provides a method of philosophical inquiry which enables us to move past this and continue our inquiry without the possibility of solipsism arising as a philosophical problem in the (...) first place. In this paper, I propose that Wittgenstein’s method of dismissing the Cartesian sceptic can also be applied to the problems posed by the ‘moral sceptic’, who denies the truth of all ethical or moral claims. I will argue that in the same way Wittgenstein’s focus on public language enables us to dismiss the traditional problem of other minds, a focus on public moral practices or language-games also enables us to dismiss the idea that moral claims are always ‘meaningless’, ‘false’ or ‘nonsensical’. On this account, the moral sceptic is misguided in much the same way as the solipsist who implicitly admits the existence of other minds in her practices. The moral sceptic who still engages in moral activities also implicitly admits the existence of meaningful moral positions. Wittgenstein’s dismissal of the Cartesian sceptic, as I understand it, can be broadly divided into two parts. The first part is an account of language acquisition. This part outlines how we might come to see other humans as conscious, thinking, feeling beings from a causal perspective. This suggests that we can arrive at an understanding of other minds as a primary perception itself - without needing to posit this perception as a kind of deductive or inductive hypothesis. Secondly, we can see how this relates to an epistemic model of language. This focuses on the role of language as something which consists of rule-governed activities, where the existence of other minds is embedded in our understanding of the world as a kind of grammatical rule, rather than an observational hypothesis. From both these arguments the Cartesian sceptic is,, irrelevant to some forms of philosophical inquiry. This is because the sceptic takes the existence of other minds to be a rational hypothesis/inference when it is not. I suggest that this approach can be applied to moral scepticism if we take certain normative claims as grammatical dispositions, rather than rational or metaphysical propositions. Hence, the moral sceptic who offers a rational or logical critique of these moral foundations is not necessarily saying anything relevant to our practices – the moral stances which they refute as rationally meaningless were never based on purely rational or logical hypotheses in the first place.

The Cartesian notion of idea is the focal point of this paper, which aims to determine whether this concept entails (a) the proposition that ideas are the immediate objects of perception, or (b) the proposition that ideas are the immediate perception of objects, or (c) both. Merely examining the Cartesian texts raises this question, as there are passages that seem to support all these positions. This discussion is not original, as it delves into one of the (...) key questions that Cartesian philosophy posed to the philosophical discourse on the problem of knowledge in the seventeenth century and beyond, an inquiry that continues to reverberate in contemporary commentaries and studies on these theories. The hypothesis that I propose to defend is as follows: once the foundational principle of clarity and distinctness is established, it is necessary to affirm that the subject perceives the objects represented in the ideas that serve as the basis for true judgments, without excluding the proposition that the subject also perceives the ideas themselves. In other words, it is essential to consider that the Cartesian concept of idea encompasses both the object immediately perceived and, in certain cases, the immediate perception of the object.

This work tries to demonstrate, in first place, that the “gnoseological” approach to the question for the science defended by Gustavo Bueno in fact only fits in the gnoseological materialism, the theory proposed by Bueno, while adequationism, theoreticism and descriptionsm would be theories of the science that genuinely would adopt the “epistemological” approach. In second place, we sustain that the epistemological and gnoseological approaches are generated in the soul/body alternative outlined by Cartesian dualism, because while the first one conceives (...) the subject that makes the sciences as a mere mind that operates with propositions or concepts “about the things”, the second one understands it as a (soulless) mechanical body that builds the sciences operating “with the things themselves”. Since in Descartes the soul is the instance that knows, the option for the body of the gnoseological materialism explains its (self) positioning regardless of the question of knowledge. Lastly, we examine some problems that this Cartesian notion of subject implicates for the gnoseological materialism’s conception of “human and ethological sciences”. (shrink)

The two main topics of the paper are an allegedly justified reliability requirement for knowledge and an alleged incoherence among three propositions asserted by Cartesian foundationalism. It is argued that neither the allegation of justified reliability nor the allegation of incoherence is correct.

Donald Davidson and John Searle famously differ, among other things, on the issue of animal thoughts. Davidson seems to be a latter-day Cartesian, denying any propositional thought to subhuman animals, while Searle seems to follow Hume in claiming that if we have thoughts, then animals do, too. Davidson’s argument centers on the idea that language is necessary for thought, which Searle rejects. The paper argues two things. Firstly, Searle eventually argues that much of a more complex thought does depend (...) on language, which reduces a distance between himself and Davidson. Secondly, some of Davidson’s suggestions are promising – in particular the idea that we may lack a vocabulary to capture the contents of animal thoughts. Based on this insight, one might, pace Davidson, grant thoughts to animals. However, this does not mean, pace Searle, that it should be possible to construe even the simplest of such thoughts as propositional. Perhaps we need to move beyond Davidson and Searle by developing a theory of nonpropositional thought for animals. (shrink)

Although linguistic nativism has received the bulk of attention in contemporary innateness debates, moral nativism has perhaps an even deeper ancestry. If linguistic nativism is Cartesian, moral nativism is Platonic. Moral nativism has taken a backseat to linguistic nativism in contemporary discussions largely because Chomsky made a case for linguistic nativism characterized by unprecedented rigor. Hence it is not surprising that recent attempts to revive the thesis that we have innate moral knowledge have drawn on Chomsky’s framework. I’ll argue, (...) however, that the recent attempts to use Chomsky-style arguments in support of innate moral knowledge are uniformly unconvincing. The central argument in the Chomskian arsenal, of course, is the Poverty of the Stimulus (POS) argument. In section 1, I will set out the basic form of the POS argument and the conclusions about domain specificity and innate propositional knowledge that are supposed to follow. In section 2, I’ll distinguish 3 hypotheses about innateness and morality: rule nativism, moral principle nativism, and moral judgment nativism. In sections 3-5 I’ll then consider each of these hypotheses in turn. I’ll argue that while there is some reason to favor rule nativism, the arguments that moral principles and moral judgment derive from innate moral knowledge don’t work. The capacity for moral judgment is better explained by appeal to innate affective systems rather than innate moral knowledge. In the final section, I’ll suggest that the role of such affective mechanisms in structuring the mind complicates the standard picture about poverty of the stimulus arguments and nativism. For the affective mechanisms that influence cognitive structures can make contributions that are neither domain general nor domain specific. (shrink)
