The first attempt at a systematic approach to axiomatic theories of truth was undertaken by Friedman and Sheard (Ann Pure Appl Log 33:1–21, 1987). There twelve principles consisting of axioms, axiom schemata and rules of inference, each embodying a reasonable property of truth were isolated for study. Working with a base theory of truth conservative over PA, Friedman and Sheard raised the following questions. Which subsets of the Optional Axioms are consistent over the base theory? What are the proof-theoretic strengths (...) of the consistent theories? The first question was answered completely by Friedman and Sheard; all subsets of the Optional Axioms were classified as either consistent or inconsistent giving rise to nine maximal consistent theories of truth.They also determined the proof-theoretic strength of two subsets of the Optional Axioms. The aim of this paper is to continue the work begun by Friedman and Sheard. We will establish the proof-theoretic strength of all the remaining seven theories and relate their arithmetic part to well-known theories ranging from PA to the theory of ${\Sigma^1_1}$ dependent choice.

Graham Hubbs | : Philosophical accounts of self-deception have tended to focus on what is necessary for one to be in a state of self-deception or how one might arrive at such a state. Less attention has been paid to explaining why, so often, self-deceived individuals resist the proper explanation of their condition. This resistance may not be necessary for self-deception, but it is common enough to be a proper explanandum of any adequate account of the phenomenon. The goals (...) of this essay are to analyze this resistance, to argue for its importance to theories of self-deception, and to offer a view of self-deception that adequately accounts for it. The view’s key idea is that, in at least some familiar cases, self-deceived individuals maintain their condition by confusing a nonepistemic satisfaction they take in their self-deceived beliefs for the epistemic satisfaction that is characteristic of warranted beliefs. Appealing to this confusion can explain both why these self-deceived individuals maintain their unwarranted belief and why they resist the proper explanation of their condition. If successful, the essay will illuminate the nature of belief by examining the limits of the believable. | : Les explications philosophiques de l’auto-illusion ont eu tendance à mettre l’accent sur ce qui est nécessaire pour que quelqu’un soit considéré comme étant sous l’emprise de l’auto-illusion ou encore sur la façon dont quelqu’un parvient à un tel état. Moins d’efforts ont été dirigés vers les raisons pour lesquelles, si souvent, les individus sous l’emprise de l’auto-illusion opposent une résistance à l’explication véritable de leur condition. Cette résistance n’est peut-être pas essentielle à l’auto-illusion, mais elle est suffisamment courante pour constituer un explicandum approprié pour tout traitement adéquat du phénomène. Cet essai a pour buts d’analyser cette résistance, de défendre son importance pour les théories de l’auto-illusion, et de proposer une conception de l’auto-illusion qui en rend compte de manière adéquate. Cette conception repose sur l’idée suivante : au moins dans certains cas connus, les individus sous l’emprise de l’auto-illusion maintiennent leur condition en prenant la satisfaction non-épistémique qu’ils retirent de leurs croyances illusoires pour la satisfaction épistémique qui caractérise les croyances justifiées. C’est en faisant appel à cette confusion que l’on peut expliquer à la fois pourquoi ces individus conservent leur croyance infondée et pourquoi ils opposent une résistance à l’explication adéquate de leur condition. Si tant est qu’il y parvienne, cet essai éclairera la nature de la croyance en examinant les limites du croyable. (shrink)

"Qu'est-ce qu'une chose? " Question déjà ancienne. Elle n'est toujours neuve que parce qu'il faut sans cesse la poser à nouveau ", observait Heidegger. C'est le traitement de cette question fondamentale de la métaphysique qu'entreprend, à nouveaux frais, Graham Harman en proposant une théorie originale de l'objet compris comme une unité autonome et concrète. Un objet, en effet, n'est jamais épuisé par l'usage ou la connaissance que j'en prends. Sa réalité ne se réduit pas non plus aux interactions qu'il (...) peut avoir avec les autres objets qui l'entourent. II outrepasse toute perspective et toute synthèse qui prétendraient le soumettre, possédant un " en soi " qui, enfoui dans les profondeurs mêmes de l'être, en assure l'altérité radicale. La question Qu'est-ce qu'une chose? en cache donc une autre, plus inquiétante : Comment penser ce qui, du réel, ne se montre en aucun cas? Rouvrant un dossier qui semblait clos depuis la mise au ban de la " chose en soi " kantienne, l'auteur trouve dans la phénoménologie les concepts de base de cette remarquable aventure ontologique : dans la pensée husserlienne de l'objet intentionnel et, plus encore, dans l'analyse heideggérienne de l'outil dont Graham Harman suggère la continuité avec le thème mystérieux du " Quadriparti ". C'est alors que l'objet pourra se laisser penser dans toute sa profondeur, réalité multipolaire et conflictuelle, à la fois manifeste et retirée, dont le présent ouvrage dessine la carte inédite".

Cognitively engaging physical activity has been suggested to have superior effects on cognition compared to PA with low cognitive demands; however, there have been few studies directly comparing these different types of activities. The aim of this study is to compare the cognitive effects of a combined physically and cognitively engaging bout of PA to a physical or cognitive activity alone in children. Children were randomized in pairs to one of three 20-min conditions: a cognitive sedentary activity; a non-cognitively engaging (...) PA; and a cognitively engaging PA. Executive function was assessed using a modified Eriksen flanker task immediately before and 10–15 min following the experimental condition. Children ages 6–8 years were included in the study. A repeated measures ANOVA found no significant difference between groups with respect to scores on the flanker task. The results do not support the hypotheses that a cognitively engaging bout of PA enhances cognitive performance over non-cognitively engaging PA or sedentary activities. Possible explanations for our findings include overexertion during the acute bout of PA and depletion of positive affect prior to performing the post-intervention EF tasks. (shrink)

RésuméCet article discute diverses confusions, actueles ou potentielles, liées á la bivalence et au tiers exclu. Il s'agit, en particulier, 1) d'examiner divers cas illustrant les rapports entre la bivalence et le tiers exclu ; 2) de discuter la thése selon laquelle le tiers exclu et le schéma-T de Tarskipour la vérité entraînent la bivalence; 3) de proposer quelques remarques sur les rapports entre la bivalence, le tiers exclu et la preuve par l'absurde; 4) de scruter un argument répandu selon (...) lequel le tiers exclu vaut pour les termes «précis» et 5) de commenter l'histoire de la terminologie. L'objectif ici est d'attirer l'attention des philosophes sur une distinction importante qui ne reçoit pas souvent le traitement minutieux qu'elle mérite. (shrink)

Les délires sont des composantes cruciales de nombreux troubles psychiques, surtout la schizophrénie. Que sont les délires? Selon l’opinion courante, il s’agit d’un type de croyance, plus précisément, une croyance pathologique. Malheureusement, l’opinion courante ne correspond pas rigoureusement, dans tous les cas, à la pratique clinique, où l’expression « délire » est souvent appliquée à des états qui ne sont pas des croyances. Nous examinons les raisons pour lesquelles des états qui ne sont pas des croyances peuvent être considérés comme (...) des délires. Nous soutenons que les délires sont des structures complexes d’attitudes d’ordre supérieur et inférieur. Ils constituent un type spécifique de défaillance de la connaissance et de la gestion de soi. Nous fournirons une description du type en question. Notre point de vue implique sur le plan conceptuel que les croyances ne sont pas essentielles aux délires.Delusions are critical components in a number of mental disorders, schizophrenia formost. What are they? The standard view is that they are a type of belief — a pathological belief. Unfortunately, the standard view does not consistently correspond to clinical practice, where the term « delusion » often applies to non-beliefs. We review the case for saying that non-beliefs can count as delusions. We argue that delusions are complexes of higher and lower order attitudes. They constitute a distinctive type of failure of self-knowledge and self-management. We describe the relevant type. One of the conceptual implications of our view is that beliefs need not be central to delusions. (shrink)

Les deux thèses principales de ce livre sont d’une part que les premiers penseurs ioniens, Anaximandre, Anaximène, Héraclite, ne furent pas des partisans du « monisme matériel », comme le voulait Aristote, d’autre part que les physiciens du ve siècle, Anaxagore et Empédocle, et dans un second temps les atomistes, loin de s’opposer à Parménide, furent en réalité ses héritiers : ils acceptèrent sa critique de la théorie du changement défendue par les premiers Ioniens (nommée par l’auteur Genera...

Graham Priest's In Contradiction (Dordrecht: Martinus Nijhoff Publishers, 1987, chapter 3) contains an argument concerning the intuitive, or ‘naïve’ notion of (arithmetic) proof, or provability. He argues that the intuitively provable arithmetic sentences constitute a recursively enumerable set, which has a Gödel sentence which is itself intuitively provable. The incompleteness theorem does not apply, since the set of provable arithmetic sentences is not consistent. The purpose of this article is to sharpen Priest's argument, avoiding reference to informal notions, consensus, (...) or Church's thesis. We add Priest's dialetheic semantics to ordinary Peano arithmetic PA, to produce a recursively axiomatized formal system PA★ that contains its own truth predicate. Whether one is a dialetheist or not, PA★ is a legitimate, rigorously defined formal system, and one can explore its proof‐theoretic properties. The system is inconsistent (but presumably non‐trivial), and it proves its own Gödel sentence as well as its own soundness. Although this much is perhaps welcome to the dialetheist, it has some untoward consequences. There are purely arithmetic (indeed, Π0) sentences that are both provable and refutable in PA★. So if the dialetheist maintains that PA★ is sound, then he must hold that there are true contradictions in the most elementary language of arithmetic. Moreover, the thorough dialetheist must hold that there is a number g which both is and is not the code of a derivation of the indicated Gödel sentence of PA★. For the thorough dialetheist, it follows ordinary PA and even Robinson arithmetic are themselves inconsistent theories. I argue that this is a bitter pill for the dialetheist to swallow. (shrink)

What did Immanuel Kant really think about love? This book is the first in-depth study of the concept of love in Kant's philosophy. It argues that love is much more important to Kant than previously thought, and that understanding love is actually essential for Kantian ethical life. Perhaps surprisingly, for Kant, love permeates human existence from the strongest impulses of nature to the highest ideals of morally deserved happiness.

What does it take for one proposition to be closer to the truth than another. In this, the first published monograph on the topic, Oddie develops a comprehensive theory that takes the likeness in truthlikeness seriously.

This article is a brief overview of major ontological arguments. The most noteworthy feature of this article is the statement of a new parody of the Anselmian and Cartesian arguments that is obviously immune to objections adverting to intrinsic minima and maxima.

Two different programmes are in the business of explicating accuracy—the truthlikeness programme and the epistemic utility programme. Both assume that truth is the goal of inquiry, and that among inquiries that fall short of realizing the goal some get closer to it than others. Truthlikeness theorists have been searching for an account of the accuracy of propositions. Epistemic utility theorists have been searching for an account of the accuracy of credal states. Both assume we can make cognitive progress in an (...) inquiry even while falling short of the target. I show that the prospects for combining these two programmes are bleak. A core accuracy principle, proximity, that is universally embraced within the truthlikeness programme turns out to be incompatible with a central principle within the epistemic utility programme, namely propriety. 1Truthlikeness and Epistemic Utility 2Inquiries 3Accuracy for Propositions 4Proximity 5Accuracy for Credal States 6Propriety 7Proximity for Credal States 8Extensionality 9Admissible Weightings 10Propriety Violates Proximity 11Possible Responses 11.1Retreat to convexity 11.2Reject boundedness 11.3Reject additivity 12The Upshot.

In a sample of 522 police officers and staff in an English police force, we investigated the role of authoritarian leadership in reducing the levels of employee ethical voice. Drawing upon uncertainty management theory, we found that authoritarian leadership was negatively related to employee ethical voice through increased levels of felt uncertainty, when the effects of a motivational-based mechanism suggested by previous studies were controlled. In addition, we found that the negative relationship between authoritarian leadership and employee ethical voice via (...) felt uncertainty is mitigated by higher levels of benevolent leadership. That is, when authoritarian leaders simultaneously exhibit benevolence, they are less likely to cause feelings of uncertainty in their followers who are then more likely to speak up about unethical issues. We discuss theoretical and practical implications of the findings. (shrink)

In this paper, I will argue that Locke is a substance dualist in the general sense, in that he holds that there are, independent of our classificatory schema, two distinct kinds of substances: wholly material ones and wholly immaterial ones. On Locke’s view, the difference between the two lies in whether they are solid or not, thereby differentiating him from Descartes. My way of establishing Locke as a general substance dualist is to be as minimally committal as possible at the (...) outset, especially with respect to the classic debates on Locke’s positions in this domain, including those concerning substrata, real essences, and the like. Nonetheless, I show that minimal commitments about Locke’s primary/secondary quality distinction are sufficient to derive some substantive conclusions about his positions on these issues, as well as that he is a general substance dualist.

This book provides a sustained and penetrating critique of a wide range of views in modern cognitive science and philosophy of the mind, from Turing's famous test for intelligence in machines to recent work in computational linguistic theory. While discussing many of the key arguments and topics, the authors also develop a distinctive analytic approach. Drawing on the methods of conceptual analysis first elaborated by Wittgenstein and Ryle, the authors seek to show that these methods still have a great deal (...) to offer in the field of the cognitive theory and the philosophy of mind, providing a powerful alternative to many of the positions put forward in the contemporary literature. Amoung the many issues discussed in the book are the following: the Cartesian roots of modern conceptions of mind; Searle's 'Chinese Room' thought experiment; Fodor's 'language of thought' hypothesis; the place of 'folk psychology' in cognitivist thought; and the question of whether any machine may be said to 'think' or 'understand' in the ordinary senses of these words. Wide ranging, up-to-date and forcefully argued, this book represents a major intervention in contemporary debates about the status of cognitive science an the nature of mind. It will be of particular interest to students and scholars in philosophy, psychology, linguistics and computing sciences. (shrink)

I argue that the Hume of the Treatise maintains an account of knowledge according to which (i) every instance of knowledge must be an immediately present perception (i.e., an impression or an idea); (ii) an object of this perception must be a token of a knowable relation; (iii) this token knowable relation must have parts of the instance of knowledge as relata (i.e., the same perception that has it as an object); and any perception that satisfies (i)-(iii) is an instance (...) of knowledge. I then apply this account to the case of sense perception. I argue that Hume holds that relations of impressions can be intuited, are knowable, and are necessary. For Hume, these relations constitute sensory knowledge. While Hume is rightly labeled an empiricist for many reasons, a close inspection of his account of knowledge reveals yet another way in which he deserves the label. (shrink)

Hsueh M. Qu has recently argued that Hume’s famed ‘Separability Principle’ from the Treatise entangles him in a contradiction. Qu offers a modified principle as a solution but also argues that the mature Hume would not have needed to avail himself of it, given that Hume’s arguments in the first Enquiry do not depend on this principle in any form. To the contrary, I show that arguments in the first Enquiry depend on this principle, but I agree with Qu that (...) Qu’s solution to Hume’s quandary frees him of the contradiction. Next, I compare Qu’s solution to Hume’s original position. By analysing the divergent forms of 'Hume’s Dictum’ that follow from them, I show that Qu’s solution and Hume’s original position have significantly different consequences in a range of domains, including Hume’s modality. Generally, Qu’s solution fits better with Hume’s other commitments—even though Hume often fails to recognize it—thereby increasing its plausibility. (shrink)

Some of Aristotle’s statements about the indemonstrability of the Principle of Non-Contradiction (PNC) in Metaphysics Γ 4 merit more attention. The consensus seems to be that Aristotle provides two arguments against the demonstrability of the PNC, with one located in Γ 3 and the other found in the first paragraph of Γ 4. In this article, I argue that Aristotle also relies upon a third argument for the same conclusion: the argument from truth. Although Aristotle does not explicitly state this (...) argument, it is the best argument that he could use to defend some of his statements in the second paragraph of Γ 4. Since the argument relies on only a few of Aristotle’s core views about truth, I propose that it is faithful to his considered position throughout his corpus, and it may be the strongest argument he could offer for the indemonstrability of the PNC.

There are some necessary conditions on causal relations that seem to be so trivial that they do not merit further inquiry. Many philosophers assume that the requirement that there could be no temporal gaps between causes and their effects is such a condition. Bertrand Russell disagrees. In this paper, an in-depth discussion of Russell’s argument against this necessary condition is the centerpiece of an analysis of what is at stake when one accepts or denies that there can be temporal gaps (...) between causes and effects. It is argued that whether one accepts or denies this condition, one is implicated in taking on substantial and wide-ranging philosophical positions. Therefore, it is not a trivial necessary condition of causal relations and it merits further inquiry. (shrink)

The transformative power of artificial intelligence (AI) is coming to philosophy—the only question is the degree to which philosophers will harness it. In this paper, we argue that the application of AI tools to philosophy could have an impact on the field comparable to the advent of writing, and that it is likely that philosophical progress will significantly increase as a consequence of AI. The role of philosophers in this story is not merely to use AI but also to help (...) develop it and theorize about it. In fact, we argue that philosophers have a prima facie obligation to spend significant effort in doing so, at least insofar as they should spend effort philosophizing. (shrink)

This introductory article outlines how this special issue contributes to existing scholarship that calls for a rethinking and re-evaluation of common assumptions about early modern philosophy. One way of challenging existing narratives is by questioning what role systems or systematicity play during this period. Another way of rethinking early modern philosophy is by considering assumptions about the role of philosophy itself and how philosophy can effect change in those who form philosophical beliefs or engage in philosophical argumentation. A further way (...) of advancing early modern scholarship is by examining the tight links between early modern views on metaphysics and epistemology, on the one hand, and moral, social, and political philosophy, on the other hand. Moreover, there are ongoing debates whether and how the traditional distinction between rationalism and empiricism, which has been questioned for several reasons, should be replaced. It has been proposed to replace it with a distinction between experimental and speculative philosophy, but this distinction cannot easily accommodate early modern debates concerning moral, social, and political philosophy. In addition to highlighting several ways how early modern philosophy has and can be rethought, we summarize how the papers in this special issue contribute to these ongoing efforts. (shrink)

Are things good because we desire them or do we desire them because they are good? Theories that countenance only desire-dependent values are idealist, those that countenance desire-independent values are realist. A value can be either subject-relative or subject-neutral. Subjectivism countenances only subject-relative and desire-dependent values. Subject-neutral idealism countenances at least some subject-neutral values. Realism repudiates the dependence of value on actual desires, but endorses an important relation between value and the fittingness of desires. Normative realism takes normative facts about (...) the fittingness of desires to ground the value facts, while axiological realism takes value facts to ground facts about fittingness. An important variant of axiological realism, namely representational realism, holds that desires are appearances of value, and that the fittingness of a desire is simply a matter of accurate representation.
