From a number of quarters have come attempts to answer some form of skepticism—about knowledge of the external world, freedom of the will, or moral reasons—by showing it to be performatively self-defeating. Examples of this strategy are subject to a number of criticisms, in particular the criticism that they fail to shift the burden of proof from the anti-skeptical position, and so fail to establish the epistemic entitlement they seek. To these approaches I contrast one way of understanding Kant’s core (...) anti-skeptical arguments in the Critique of Pure Reason. Kant’s goal is the more modest one of showing the applicability of the concepts of substance and cause to experience, against those who might call such application incoherent, or a category mistake. I explain why this goal makes Kant’s approach more promising than those of neo-Kantian practitioners of otherwise structurally-similar strategies. (shrink)

‘Performative’ transcendental arguments exploit the status of a subcategory of self-falsifying propositions in showing that some form of skepticism is unsustainable. The aim of this paper is to examine the relationship between performatively inconsistent propositions and transcendental arguments, and then to compare performative transcendental arguments to modest transcendental arguments that seek only to establish the indispensability of some belief or conceptual framework. Reconceptualizing transcendental arguments as performative helps focus the intended dilemma for the skeptic: performative transcendental arguments directly confront the (...) skeptic with the choice of abandoning either skepticism or some other deep theoretical commitment. Many philosophers, from Aristotle and St. Thomas Aquinas to Jaakko Hintikka, C.I. Lewis, and Bernard Lonergan, have claimed that some skeptical propositions regarding knowledge, reason, and/or morality can be shown to be self-defeating; that is to say, they have claimed that the very upholding of some skeptical position is in some way incompatible with the position being upheld, or with the implied, broader dialectical position of the skeptic in question. Statements or propositions alleged to have this characteristic also sometimes are called ‘self-falsifying,’ ‘self-refuting,’ ‘self-stultifying,’ ‘self-destructive,’ or ‘pointless.’ However, proponents of the strategy of showing skepticism to be self-defeating have not in general adequately distinguished between two types of self-defeating proposition: self-falsifying and self-stultifying. In the first part of this paper I distinguish between self-falsifying and self-stultifying propositions, and introduce the notion of performative self-falsification. In the second part I discuss classical transcendental arguments, ‘modest’ transcendental arguments, and objections to each. In the third part I introduce two types of transcendental argument—each labeled “performative”—corresponding to two types of performatively self-falsifying proposition, and I compare them to modest transcendental arguments.

It is available under its title through PhilPapers and other philosophy online archives. ●●●●● COMMENDATIONS OF THIS WORK, from the back cover of the published edition: ●●●●● “I admire its range of philosophical vision.” – Nicholas Rescher, Distinguished University Professor of Philosophy, University of Pittsburgh, author of more than 100 books. ●●●●● “Bartlett’s _Critique of Impure Reason_ is an impressive, bold, and ambitious work. Careful scholarship is balanced by original analyses that lead the reader to recognize the limits of meaning, knowledge, and conceptual possibility. The work addresses a host of traditional philosophical problems, among them the nature of space, time, causality, consciousness, the self, other minds, ontology, free will and determinism, and others. The book culminates in a fascinating and profound new understanding of relativity physics and quantum theory.” – Gerhard Preyer, Professor of Philosophy, Goethe-University, Frankfurt am Main, Germany, author of many books including _Concepts of Meaning_, _Beyond Semantics and Pragmatics_, _Intention and Practical Thought_, and _Contextualism in Philosophy_. ●●●●● “[This work’s] goal is of a unique and difficult species: Dr. Bartlett seeks to develop a formal logical calculus on the basis of transcendental philosophical arguments; in fact, he hopes that this calculus will be the formal expression of the transcendental foundation of knowledge.... I consider Dr. Bartlett’s work soundly conceived and executed with great skill.” – C. F. von Weizsäcker, philosopher and physicist, former Director, Max-Planck-Institute, Starnberg, Germany. ●●●●● “Bartlett has written an American “Prolegomena to All Future Metaphysics.” He aims rigorously to eliminate meaningless assertions, reach bedrock, and place philosophy on a firm foundation that will enable it, like science and mathematics, to produce lasting results that generations to come can build on. This is a great book, the fruit of a lifetime of research and reflection, and it deserves serious attention.” — Martin X. Moleski, former Professor, Canisius College, Buffalo, NY, studies of scientific method, the presuppositions of thought, and the self-referential nature of epistemology. ●●●●● “Bartlett has written a book on what might be called the underpinnings of philosophy. It has fascinating depth and breadth, and is all the more striking due to its unifying perspective based on the concepts of reference and self-reference.” – Don Perlis, Professor of Computer Science, University of Maryland, author of numerous publications on self-adjusting autonomous systems and philosophical issues concerning self-reference, mind, and consciousness. ●●●●● ●●●●● The _Critique of Impure Reason: Horizons of Possibility and Meaning_ comprises a major and important contribution to philosophy. Thanks to the generosity of its publisher, this massive 885-page volume has been published as a free open access eBook (3.75MB) as well as an open access printed edition. It inaugurates a revolutionary paradigm shift in philosophical thought by providing compelling and long-sought-for solutions to a wide range of philosophical problems. In the process, the work fundamentally transforms the way in which the concepts of reference, meaning, and possibility are understood. The book includes a Foreword by the celebrated German philosopher and physicist Carl Friedrich von Weizsäcker. ●●●●● In Kant’s _Critique of Pure Reason_ we find an analysis of the preconditions of experience and of knowledge. In contrast, but yet in parallel, the new _Critique_ focuses upon the ways—unfortunately very widespread and often unselfconsciously habitual—in which many of the concepts that we employ _conflict_ with the very preconditions of meaning and of knowledge. ●●●●● This is a book about the boundaries of frameworks and about the unrecognized conceptual confusions in which we become entangled when we attempt to transgress beyond the limits of the possible and meaningful. We tend either not to recognize or not to accept that we all-too-often attempt to trespass beyond the boundaries of the frameworks that make knowledge possible and the world meaningful. ●●●●● The _Critique of Impure Reason_ proposes a bold, ground-breaking, and startling thesis: that a great many of the major philosophical problems of the past can be solved through the recognition of a viciously deceptive form of thinking to which philosophers as well as non-philosophers commonly fall victim. For the first time, the book advances and justifies the criticism that a substantial number of the questions that have occupied philosophers fall into the category of “impure reason,” violating the very conditions of their possible meaningfulness. ●●●●● The purpose of the study is twofold: first, to enable us to recognize the boundaries of what is referentially forbidden—the limits beyond which reference becomes meaningless—and second, to avoid falling victims to a certain broad class of conceptual confusions that lie at the heart of many major philosophical problems. As a consequence, the boundaries of _possible meaning_ are determined. ●●●●● Bartlett, the author or editor of more than 20 books, is responsible for identifying this widespread and delusion-inducing variety of error, _metalogical projection_. It is a previously unrecognized and insidious form of erroneous thinking that undermines its own possibility of meaning. It comes about as a result of the pervasive human compulsion to seek to transcend the limits of possible reference and meaning. ●●●●● Based on original research and rigorous analysis combined with extensive scholarship, the _Critique of Impure Reason_ develops a self-validating method that makes it possible to recognize, correct, and eliminate this major and pervasive form of fallacious thinking. In so doing, the book provides at last provable and constructive solutions to a wide range of major philosophical problems. ●●●●● CONTENTS AT A GLANCE ▪▪▪▪▪ Preface ▪▪▪▪▪ Foreword by Carl Friedrich von Weizsäcker ▪▪▪▪▪ Acknowledgments ▪▪▪▪▪ Avant-propos: A philosopher’s rallying call ▪▪▪▪▪ Introduction ▪▪▪▪▪ A note to the reader ▪▪▪▪▪ A note on conventions ▪▪▪▪▪ ▪▪▪▪▪ ▪▪▪▪▪ PART I ▪▪▪▪▪ ▪▪▪▪▪ WHY PHILOSOPHY HAS MADE NO PROGRESS AND HOW IT CAN ▪▪▪▪▪ 1 Philosophical-psychological prelude ▪▪▪▪▪ 2 Putting belief in its place: Its psychology and a needed polemic ▪▪▪▪▪ 3 Turning away from the linguistic turn: From theory of reference to metalogic of reference ▪▪▪▪▪ 4 The stepladder to maximum theoretical generality ▪▪▪▪▪ ▪▪▪▪▪ ▪▪▪▪▪ PART II ▪▪▪▪▪ THE METALOGIC OF REFERENCE ▪▪▪▪▪ A New Approach to Deductive, Transcendental Philosophy ▪▪▪▪▪ 5 Reference, identity, and identification ▪▪▪▪▪ 6 Self-referential argument and the metalogic of reference ▪▪▪▪▪ 7 Possibility theory ▪▪▪▪▪ 8 Presupposition logic, reference, and identification ▪▪▪▪▪ 9 Transcendental argumentation and the metalogic of reference ▪▪▪▪▪ 10 Framework relativity ▪▪▪▪▪ 11 The metalogic of meaning ▪▪▪▪▪ 12 The problem of putative meaning and the logic of meaninglessness ▪▪▪▪▪ 13 Projection ▪▪▪▪▪ 14 Horizons ▪▪▪▪▪ 15 De-projection ▪▪▪▪▪ 16 Self-validation ▪▪▪▪▪ 17 Rationality: Rules of admissibility ▪▪▪▪▪ ▪▪▪▪▪ ▪▪▪▪▪ PART III ▪▪▪▪▪ PHILOSOPHICAL APPLICATIONS OF THE METALOGIC OF REFERENCE ▪▪▪▪▪ Major Problems and Questions of Philosophy and the Philosophy of Science ▪▪▪▪▪ 18 Ontology and the metalogic of reference ▪▪▪▪▪ 19 Discovery or invention in general problem-solving, mathematics, and physics ▪▪▪▪▪ 20 The conceptually unreachable: “The far side” ▪▪▪▪▪ 21 The projections of the external world, things-in-themselves, other minds, realism, and idealism ▪▪▪▪▪ 22 The projections of time, space, and space-time ▪▪▪▪▪ 23 The projections of causality, determinism, and free will ▪▪▪▪▪ 24 Projections of the self and of solipsism ▪▪▪▪▪ 25 Non-relational, agentless reference and referential fields ▪▪▪▪▪ 26 Relativity physics as seen through the lens of the metalogic of reference ▪▪▪▪▪ 27 Quantum theory as seen through the lens of the metalogic of reference ▪▪▪▪▪ 28 Epistemological lessons learned from and applicable to relativity physics and quantum theory ▪▪▪▪▪ ▪▪▪▪▪ PART IV ▪▪▪▪▪ HORIZONS ▪▪▪▪▪ 29 Beyond belief ▪▪▪▪▪ 30 _Critique of Impure Reason_: Its results in retrospect ▪▪▪▪▪ ▪▪▪▪▪ SUPPLEMENT ▪▪▪▪▪ The Formal Structure of the Metalogic of Reference ▪▪▪▪▪ APPENDIX I ▪▪▪▪▪ The Concept of Horizon in the Work of Other Philosophers ▪▪▪▪▪ APPENDIX II ▪▪▪▪▪ Epistemological Intelligence ▪▪▪▪▪ References ▪▪▪▪▪ Index ▪▪▪▪▪ About the author.

Self-verifying judgments like _I exist_ seem rational, and self-defeating ones like _It will rain, but I don’t believe it will rain_ seem irrational_._ But one’s evidence might support a self-defeating judgment, and fail to support a self-verifying one. This paper explains how it can be rational to defy one’s evidence if judgment is construed as a mental performance or act, akin to inner assertion. The explanation comes at significant cost, however. Instead of causing or constituting beliefs, judgments turn out to (...) be mere epiphenomena, and self-verification and self-defeat lack the broader philosophical import often claimed for them.

There is extensive literature that indicates animals suffer considerably in the practices of factory farming and animal experimentation. In the light of the evidence of this suffering there is an urgent need to answer the question whether our current use of animals is ever morally justifiable. The aim of this thesis is to provide a critical examination of the moral status of animals and of our treatment of animals in these practices. My objective is to assess whether these practices are (...) ever justifiable and whether we have a moral obligation to revise our attitudes towards our use of animals. Animals are often denied moral standing on the basis that they lack certain capacities, such as rationality, language and the ability to think. Further, it is often thought that animals' supposed lack of such capacities could be used as a defence for our use of them in intensive farming and animal experimentation. Thus, in examining the moral status of animals this thesis also examines animals and their capacities in order to determine whether any of the arguments given against the moral standing of animals are sound. In seeking to discover the extent of our moral obligations towards animals and the necessary conditions for moral standing, I will demonstrate that, although animals used in factory farming and experiments do have moral standing, the only consistent course is to extend moral standing to all living things. I will conclude that although the possession of certain much-prized capacities is not necessary for moral standing, many animals do indeed possess such capacities, including the ability to use language. Centrally this thesis calls for a re-evaluation of our attitudes towards animals, particularly in respect of our beliefs about animals used in factory farms and experiments. (shrink)

This paper argues against the moral Turing test as a framework for evaluating the moral performance of autonomous systems. Though the term has been carefully introduced, considered, and cautioned about in previous discussions :251–261, 2000; Allen and Wallach 2009), it has lingered on as a touchstone for developing computational approaches to moral reasoning :98–109, 2015). While these efforts have not led to the detailed development of an MTT, they nonetheless retain the idea to discuss what kinds of action and reasoning (...) should be demanded of autonomous systems. We explore the flawed basis of an MTT in imitation, even one based on scenarios of morally accountable actions. MTT-based evaluations are vulnerable to deception, inadequate reasoning, and inferior moral performance vis a vis a system’s capabilities. We propose verification—which demands the design of transparent, accountable processes of reasoning that reliably prefigure the performance of autonomous systems—serves as a superior framework for both designer and system alike. As autonomous social robots in particular take on an increasing range of critical roles within society, we conclude that verification offers an essential, albeit challenging, moral measure of their design and performance.

À partir de l’indécision apparente du concept de substance dans le corpus cartésien, on formule l’hypothèse que le « traité de la substance » des Principia I peut jeter une lumière sur les Meditationes (§ 1) ; en effet les Principia I développent deux définitions de la substance, tantôt comme chose existante par soi, tantôt comme support des attributs (§ 2) ; or ces deux définitions correspondent exactement aux deux lieux des Meditationes mobilisant la substance : la Meditatio III recourt (...) à la substance des Principia I, 51, et la Meditatio VI recourt à la substance des Principia I, 52 (§ 3). On en déduit que le cogito de la Meditatio II ne saurait remonter de l’attribut principal à la substance suivant la logique de Principia I, 52 (§ 4) et que l’ ego, alors entendu selon Principia I, 51, ne pouvait que perdre sa substantialité dès l’instant que se trouvait exhibée sa dépendance envers Dieu, à la fin de la Meditatio III (§ 5). Dès lors, les Principia nous paraissent trancher des indécisions cartésiennes avec une certaine efficacité (§ 6). (shrink)

There are several paradigms of 'first philosophy' (e.g. Aristotle, Descartes). A third paradigm of first philosophy is transcendental pragmatics or transcendental semiotics (exemplified by Peirce and Wittgenstein). Husserl correctly grasped that Descartes inaugurated first philosophy in the sense of a transcendental inquiry into the foundations of absolute knowledge. But Husserl's retrieval of Descartes remains within the second paradigm in that it ignores the role of language as a condition of the possibility of objectively constituted knowledge. I propose to re-examine Descartes's (...) conception of first philosophy to see if it can be read in the light of the third paradigm of transcendental philosophy, namely transcendental semiotics. I argue that Cartesian methodic doubt can be rehabilitated (against Wittgenstein's critique) as a kind of 'fallibilistic' approach to knowledge of a Peircean kind, and that the Cartesian cogito can be read (following Hintikka) as recognition of performative contradiction and of the necessity of speech acts, and hence of the transcendental communication community.

In this paper we investigate the role of performative contradictions in legal discourse. First of all we identify the argumentative roles of performative contradictions and two possible interpretations of them. With this done, we show that one use of performative contradictions can be fruitfully applied in analysing normative speech acts implementing norm enactment, namely, those speech acts that are designed to produce new legal norms. We conclude the paper by showing that our analysis provides strong support for Robert Alexy's claim‐to‐correctness (...) thesis, according to which speech acts of the norm‐enacting kind raise a claim to correctness.

Considerando que o cogito possa ser tomado, nas Meditações, como uma conclusão de uma demonstração, pode-se avançar a tese de que essa demonstração está consoante ao método analítico, que Descartes reconhece empreender nesse texto. Esse método teria entre as suas funções nas Meditações aquela de apresentar – sob a forma de uma rede de implicações ontológicas – o raciocínio que conduz à certeza da existência. Como cumpre no referido texto determinar a certeza da existência sem tomar como base nenhuma certeza (...) preestabelecida, o método analítico financiaria, segundo a nossa interpretação, uma reconstrução do argumento do cogito sob uma base indireta, mais precisamente através de uma reductio ad absurdum, cujo objetivo consiste em mostrar a contradição inelutável que surge na tentativa de um indivíduo de provar a sua não existência.

In this introduction, I consider different problems posed by the use of singular terms in fiction (section 1), paying especial attention to proper names and, in particular, to names of real people, places, etc. As we will see (section 2), descriptivist and Millian theories of reference face different kinds of problems in explaining the use of fictional names in fiction-related contexts. Moreover, the task of advancing a uniform account of names in these contexts—an account which deals not only with fictional (...) names but also with “real” names—will prove to be very hard no matter whether we favour realist or antirealist intuitions about fictional discourse (section 3). Section 4 offers an overview of the content of this volume, with emphasis on the discussion between Manuel García-Carpintero and Stacie Friend about the meaning of “real” names in fiction-related contexts, the main topic of the Third Blasco Disputatio.

This is a work in the philosophy of language and metasemantics. Its purpose is to help answer the question about how words acquire their meanings. The work is divided into two parts. The purpose of Part One is to defend the claim that, despite numerous attempts, the so-called Kripkenstein’s sceptical challenge, and especially the problem of finitude, has not been offered a successful straight solution. The purpose of Part Two is to critically examine Robert Brandom’s philosophy, which can be treated (...) as an answer to the sceptical challenge in my interpretation. My main claim is that although Brandom’s so-called normativist approach does provide a principled solution to the sceptical challenge, the proposal faces a host of other problems in the light of which I reject it. -/- What is Kripkenstein’s sceptical challenge? The name 'Kripkenstein' is an abbreviation used in the literature for Saul Kripke’s reading of Ludwig Wittgenstein’s later works, published in 1982. In the long essay, Kripke presents (that Wittgenstein presented) a sceptical challenge that demands an explanation of how any word can have a determinate meaning. The challenge is usually thought to consist of three interrelated problems: (1) the problem of finitude, (2) the problem of error, and (3) the problem of normativity. Following Martin Kusch, I view the problem of finitude as the most important one. According to the problem, briefly, since any actual subject is a finite being, i.e. capable of exhibiting only finite expressions of linguistic signs, it will always be possible to ask whether, in a given context, she is following a rule S1 or rule S2 that corresponds to the meaning of the sign. For example, supposing that the sign in question is '+', it can be asked whether the subject in a given context has followed the addition rule or an alternative quaddition rule, according to which any addition problem exceeding certain arbitrary cardinality results in five. According to the hypothesis, the actual use of '+' by any speaker is compatible with both rules. Since any speaker has only finite dispositions to the mathematical conduct, there will always be some limit after which there is no fact of the matter, according to the sceptic, which rule the subject will have turned out to have followed. Hence, it is indeterminate whether any actual subject has ever calculated according to the addition rule or the quaddition rule. -/- From my view, despite the work of Kripke and Kusch, the problem of finitude has not been taken as seriously as it ought to have been. This in turn has significant consequences for the metasemantic theory concerning the origin and nature of meaning. In particular, I claim that the way how the meaning of words is determined must be understood as temporal in nature. Moreover, I claim that Kripke’s causal-historical account of reference can work as a non-straight solution to the challenge that explains how at least the meanings of some words can be temporally determined. -/- One central aim of Brandom’s philosophy is to give a straight answer to the problem of finitude by providing an answer to the problem of normativity. However, I claim that Brandom’s version of the 'normativity of meaning' hypothesis cannot work as he intends. The key issues are difficult to summarise, but to put it succinctly, the crucial problem concerns Brandom’s ambition to give an answer to a version of Agrippa’s trilemma, or how a chain of justifications can end in anything else than (i) premises that have already been used, (ii) a primitive premise, or an (iii) infinitude of premises. My claim is that Brandom’s resolution to the trilemma is not sound. (shrink)

Why would Rene Descartes, the father of modern rationalist philosophy, choose "meditations" -- a term and genre associated with religious discourse and practice -- for the title of his magnum opus that lays the metaphysical foundations for his reform of all knowledge, including mathematics and sciences? Why did he believe that the immortality of the soul and the existence of God, which the Meditations on First Philosophy set out to demonstrate, can only be made self-evident through meditating? These are the (...) question that Christopher Wild's book answers. Descartes discovered the "foundations of a marvelous science" through a dramatic conversion in southern Germany in the winter of 1619. The spiritual and cognitive exercises, derived from ancient philosophy and the Christian meditative tradition, which Descartes deployed in the Meditations, enable readers to discover metaphysical truths with the same degree of self-evidence with which Descartes did during his own conversion. Descartes' meditative turn, Wild argues, brings to a culmination a life-long preoccupation with the practice or craft of thinking, known as Cartesian method. By joining meditation to method the Meditations becomes the founding document for a Cartesian "art of turning," a new practice of both thought and life. (shrink)

An argument for the rationality of religious belief in the existence of God is defended. After reviewing three preconditions for rational belief, I show reasons to privilege the criterion of consistency. Taking the inconsistency of the religious belief in God and the belief in the scientific world picture as the impediment to a rational belief in God, I propose that we can overcome this objection by assuming, firstly, that God is a universal class. This allows us to put the problem (...) of God in set-theoretic terms, such that the antinomy that follows from such an assumption can be overcome by assuming that God is not a subject but a strict class that cannot be individuated. I conclude that that the self-contradictory nature of God does not prevent the believer from making a rational, ethical assessment that the contradiction resides in the possibility of using language to explain his existence, but that this does not make belief in the existence of God unjustifiable – on the contrary. In this way, we can say statements that claim God exists are justifiable. (shrink)

A leading philosopher takes a mind-bending journey through virtual worlds, illuminating the nature of reality and our place within it. Virtual reality is genuine reality; that's the central thesis of Reality+. In a highly original work of "technophilosophy," David J. Chalmers gives a compelling analysis of our technological future. He argues that virtual worlds are not second-class worlds, and that we can live a meaningful life in virtual reality. We may even be in a virtual world already. Along the way, (...) Chalmers conducts a grand tour of big ideas in philosophy and science. He uses virtual reality technology to offer a new perspective on long-established philosophical questions. How do we know that there's an external world? Is there a god? What is the nature of reality? What's the relation between mind and body? How can we lead a good life? All of these questions are illuminated or transformed by Chalmers' mind-bending analysis. Studded with illustrations that bring philosophical issues to life, Reality+ is a major statement that will shape discussion of philosophy, science, and technology for years to come. (shrink)

An analysis of the nature of reflexivity--a relation which relates a thing to itself although it is regularly used to relate two different things--is followed by specific discussions of its place and functions in the writings of various philosophers. These discussions substantiate the following theses: reflexivity is a basic structure common to different phenomena; although traditionally unacknowledged, it is a useful and important concept in philosophy as well as in other disciplines; acknowledging its existence and understanding its structure deepens our (...) understanding of philosophical systems; since, like any other philosophical tool, reflexivity can be used either legitimately or illegitimately, nothing in it is inherently flawed; a structural analysis of different types of reflexivity and the relations between them can be presented; the history of its use is marked by a tendency towards its "normalization". These discussions are intended to raise awareness and generate future studies of this important but neglected philosophical structure. (shrink)

The term “clear and distinct” is used by both Descartes and Husserl when they talk about the truth of an idea and the evidence of judgment. Although the words “clear” and “distinct” are juxtaposed with the conjunction “and,” this does not mean that their status is equal. If the concept of “evidence” can be used to characterize the hierarchical relationship between them, then we can say that, for Descartes, distinct evidence is higher than clear evidence. For Husserl, on the contrary, (...) clear evidence is higher than distinct evidence. Their opposing views concerning the hierarchy between clarity and distinctness is symptomatic of the differences between their two understandings of the epistemological relationship between intellect and sensibility, as well as of their respective ontological reach.

Semantic Indeterminacy and Scientific Realism are perhaps the two most ubiquitous and influential doctrines of the Quinean corpus. My concern is to argue against neither in isolation, but against their joint compatibility. Scientific Realism, I argue, when understood as Quine's realistic attitude toward the posits of physical theory, is essentially intentional in character. Thus, Realism requires Intentionality. In Section 1, I provide some necessary exegesis. In Section 2, I attempt to show how this Realism/Intentionality connection arises, surprisingly, within Quine's own (...) mature work to create a tension in his views which he does not himself resolve. In Section 3, I examine the source of the Realism/Intentionality connection more deeply, and respond to possible Quinean objections to my account. In Section 4, I consider the consequences of the connection for various debates in recent analytic philosophy. (shrink)

Pedagogical situations require white lies: in teaching philosophy we make decisions about what to omit, what to emphasise, and what to distort. This article considers when it is permissible to distort the historical record, arguing for a tempered respect for the historical facts. It focuses on the rationalist/empiricist distinction, which still frames most undergraduate early modern courses despite failing to capture the intellectual history of that period. It draws an analogy with Michael Strevens's view on idealisation in causal explanation to (...) distinguish between myths and caricatures. Myths are distortions of the historical record that undermine students' understanding of the past, despite having other pedagogical benefits. Caricatures are distortions that either increase or are indifferent to understanding of the past. Mythmaking, the article argues, is unjustified. (shrink)

That there is an epistemological difference between the mental and the physical is well- known. Introspection readily generates knowledge of one’s own conscious experience, but fails to yield evidence for the existence of anything physical. Conversely, empirical investigation delivers knowledge of physical properties, but neither finds nor requires us to posit conscious experience. In recent decades, a series of neo-Cartesian arguments have emerged that rest on this epistemological difference and purport to demonstrate that mind-brain identity is false and that consciousness (...) is not even realized by or supervenient on physical properties. Where Descartes argued he could clearly and distinctly conceive mind and body as existing separately, contemporary anti-physicalists hold that the conceivability of worlds in which actual world correlations between physical and phenomenological properties fail shows that these correlations are contingent rather than logically or metaphysically necessary. Together with Descartes, they conclude from conceivability that identity, as well as strong supervenience, is false. 1 If the argument of this paper is correct, however, then there is an argument for dualism that arises from the epistemological distinction, is grounded in the Meditations, and is yet distinct from the " 1 " conceivability arguments pursued both by Descartes and contemporary anti-physicalists. Furthermore, the argument is immune to the standard objections to conceivability arguments: its conclusion follows even if there are a posteriori identities between physical and phenomenal properties.

Is it possible to recognize the limits of rationality, and thus to embrace moral pluralism, without embracing moral relativism? My answer is yes; nevertheless, certain anti-foundational positions, both recent and ancient, take a cynical stance toward the possibility of any critical moral judgment, and as such, must be regarded as relativistic.1 It is such cynicism, I argue, whether openly announced or unknowingly implied, that marks the distinction between relativism and pluralism.2 The danger of this cynicism is not so much that (...) it renders the categorical acceptance of a particular moral view unattainable, but that it renders categorical condemnation of any particular position (or action) impossible.3 Two ..

What should the EU do about the fact that some Member States are backsliding on their commitments to democracy, supposedly a fundamental value of the EU? The Treaty provisions under Article 7 TEU are widely criticized for being ineffective in preventing such developments. Are they legitimate? I argue that the ultimate sanction of Article 7 TEU falls into a performative contradiction, which undermines its ability to coherently defend fundamental values. Instead, expulsion from the EU is the appropriate, coherent and legitimate (...) final political sanction for democratic and rule of law backsliding by a Member State. The argument has the following steps: In Part 1, I argue that the current Article 7 framework for responding to democratic and rule of law backsliding in the EU is normatively problematic, in that the mechanism currently in the Treaty undermines the values it purports to defend; in other words, it falls into a performative contradiction. It is undemocratic to deprive Member States of their right to vote in the Council while holding them subject to Council decisions. However, Part 2 studies relevant philosophical arguments from an adjacent literature on criminal disenfranchisement, concluding that allowing backsliding Member States to keep their voting rights in the Council _also_ taints the democratic character of Council decision-making. In Part 3, I consider the resulting paradox in light of the literature on militant democracy. Could militant democracy justify Article 7? I argue not; even if we accept the hypothetical justifiability of militant measures, they are not legitimate here since a democratically acceptable alternative exists that would safeguard the democratic character and legitimacy of Council decision-making: expulsion from the Union. I also address a central objection to an expulsion mechanism—that it would require treaty change and is therefore practically impossible. (shrink)

Creationists believe that C. K. Chesterton created Father Brown in his detective stories. Since creating implies a creation, Father Brown exists. Atheists object that the same reasoning could prove the existence of God. But creationists such as Jonathan Schaffer insist atheists do believe that God exists. Serious metaphysics rarely concerns existence. The disagreement between the theist and the atheist is about the nature of God, not His existence. Schaffer underestimates the religious imagination. There could be a religion that explicitly regarded (...) God as a fictional character. The tenets of this, presently hypothetical, religion are developed in a dialogue. (shrink)

What are we to make of the cogito (cogito ergo sum) today, as the walls of Cartesian philosophy crumble around us? The enduring foundation of the cogito is consciousness. It is in virtue of a particular phenomenological structure that an experience is conscious rather than unconscious. Drawing on an analysis of that structure, the cogito is given a new explication that synthesizes phenomenological, epistemological, logical, and ontological elements. What, then, is the structure of conscious thinking on which the cogito draws? (...) What kind of certainty does the experience of thinking give one about one's thinking and about one's existence? What form of inference is the cogito, and what is the source of its validity and soundness? Does the cogito itself lead to an ontology of mind and body like Descartes's dualism? The discussion begins with Descartes's own careful formulations of some of these issues. Then the cogito is parsed into several different principles, the phenomenological principle emerging as basic. In due course the analysis sifts through Husserl's epistemology, Hintikka's logic (or pragmatics) of the cogito, and Kaplan's logic of demonstratives, as these bear specifically on the cogito.

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

We are prone to gross error, even in favorable circumstances of extended reflection, about our own ongoing conscious experience, our current phenomenology. Even in this apparently privileged domain, our self-knowledge is faulty and untrustworthy. We are not simply fallible at the margins but broadly inept. Examples highlighted in this essay include: emotional experience (for example, is it entirely bodily; does joy have a common, distinctive phenomenological core?), peripheral vision (how broad and stable is the region of visual clarity?), and the (...) phenomenology of thought (does it have a distinctive phenomenology, beyond just imagery and feelings?). Cartesian skeptical scenarios undermine knowledge of ongoing conscious experience as well as knowledge of the outside world. Infallible judgments about ongoing mental states are simply banal cases of self-fulfillment. Philosophical foundationalism supposing that we infer an external world from secure knowledge of our own consciousness is almost exactly backward. (shrink)

In this paper we investigate the role of performative contradictions in legal discourse. First of all we identify the argumentative roles of performative contradictions and two possible interpretations of them. With this done, we show that one use of performative contradictions can be fruitfully applied in analysing normative speech acts implementing norm enactment, namely, those speech acts that are designed to produce new legal norms. We conclude the paper by showing that our analysis provides strong support for Robert Alexy's claim-to-correctness (...) thesis, according to which speech acts of the norm-enacting kind raise a claim to correctness.

Descartes a menudo es visto como un pensador solitario, una suerte de Robinson Crusoe metafísico. En el origen cartesiano de la filosofía moderna se unirían la actitud teórica más radical y solipsista, con el desinterés por las cuestiones prácticas que tanto habían preocupado a los pensadores que le antecedieron. No obstante, la lectura canónica de Descartes como un teórico puro, desentendido de los otros, e incluso de sí mismo, es problemática. El meditador cartesiano en realidad emerge del diálogo con un (...) interlocutor misterioso que, lo engañe o no, sin duda lo interpela. Más aún, al final de su vida Descartes esbozó una teoría de las pasiones con la admiración, el amor y la generosidad, que siempre apuntan a un alter ego, como nociones clave para alcanzar la frágil felicidad mundana. Cabe preguntarse si estos aspectos, usualmente poco atendidos, permiten aproximar a Descartes al peculiar “género” de la confesión filosófica. (shrink)

Semen Frank (1877–1950) was one of the first and most ardent advocates of the ontological argument in the twentieth century. He proposed an original interpretation of the ontological argument based on its analogy to Descartes’ Cogito. Frank believed that it is possible to develop Cogito ergo sum into Cogito ergo est ens absolutum. In this paper, I analyze his version of the ontological argument. First, I propose a simple reconstruction of his reasoning, paying attention to its hidden premise. Second, departing (...) from the classical logical interpretations of Descartes’ argument, I show that for Frank the claim that God exists had the same logical properties as Cogito. As a result, it seems that his argument was formally correct, though based on a premise which could hardly be convincing for a non-believer. This should not be surprising, however, since Frank, as most Russian religious philosophers, was not interested in the project of philosophical theology. His main concern was rather the development of philosophy based on religious premises, which might be called “theological philosophy”. (shrink)

The Many Gods Objection (MGO) is widely viewed as a decisive criticism of Pascal’s Wager. By introducing a plurality of hypotheses with infinite expected utility into the decision matrix, the wagerer is left without adequate grounds to decide between them. However, some have attempted to rebut this objection by employing various criteria drawn from the theological tradition. Unfortunately, such defenses do little good for an argument that is supposed to be an apologetic aimed at atheists and agnostics. The purpose of (...) this paper is to offer a defensive strategy of a different sort, one more suited to the Wager’s apologetic aim and status as a decision under ignorance. Instead of turning to criteria independent of the Wager, it will be shown that there are characteristics already built into its decision theoretic structure that can be used to block many categories of theological hypotheses including MGO’s more outrageous “cooked-up” hypotheses and “philosophers’ fictions”. -/- Please note that there are editorial errors in the published version.

In Descartes, the concept of a ‘universal science’ differs from that of a ‘mathesis universalis’, in that the latter is simply a general theory of quantities and proportions. Mathesis universalis is closely linked with mathematical analysis; the theorem to be proved is taken as given, and the analyst seeks to discover that from which the theorem follows. Though the analytic method is followed in the Meditations, Descartes is not concerned with a mathematisation of method; mathematics merely provides him with examples. (...) Leibniz, on the other hand, stressed the importance of a calculus as a way of representing and adding to what is known, and tried to construct a ‘universal calculus’ as part of his proposed universal symbolism, his ‘characteristica universalis’. The characteristica universalis was never completed—it proved impossible, for example, to list its basic terms, the ‘alphabet of human thoughts’—but parts of it did come to fruition, in the shape of Leibniz's infinitesimal calculus and his various logical calculi. By his construction of these calculi, Leibniz proved that it is possible to operate with concepts in a purely formal way. (shrink)

This paper explores the idea that Descartes’ cogito is a kind of diagonal argument. Using tools from modal logic, it reviews some historical antecedents of this idea from Slezak and Boos and culminates in an orginal result classifying the exact structure of belief frames capable of supporting diagonal arguments and our reconstruction of the cogito.

In constructing the concept of truth I believe to be implicit in Sartre's philosophy, I shall inevitably make glancing contact with differences between his and Descartes' understanding of the cogito—their common foundational truth. This family quarrel will, however, remain peripheral to my discussion of what I take to be the core claim of any cogito-argument: that my existence is certain insofar as it results from my thinking. Beyond that, nothing is certain about what Descartes meant by the certainty of the (...) cogito, or about what could reasonably be meant by it. His express inconsistencies in characterizing the force of his cogito-argument are well known, as are the various incompatible, textually more or less defensible, construals of generations of his interpreters. Unsurprisingly, then, the problem of truth for those of his followers, including Sartre, who have not been content to accept cogito, ergo sum as an unanalyzable datum, has tended to centre on proposing more intellectually transparent readings of their ancestor's seemingly inscrutable ergo.

Je soutiens dans cette étude que la notion de connaissance de soi introspective est au centre du Cogito de Descartes. À la suite de Hintikka, de nombreux commentateurs, dans la tradition analytique, se sont concentrés sur la justification de l’énoncé « j’existe », en lien avec l’énoncé « je pense », sans chercher à proposer une explication unifiée mettant en évidence la structure de l’argument cartésien ni son lien essentiel avec la connaissance de soi introspective. Par ailleurs, certaines des théories (...) de la connaissance de soi aujourd’hui les plus influentes, en particulier celle de Gareth Evans, se sont développées en réaction à une image supposée « cartésienne » de l’introspection héritée de Gilbert Ryle. Dans ce contexte, l’interprétation du Cogito proposée par Christopher Peacocke pourrait se révéler un jalon essentiel dans l’histoire des lectures de Descartes. Selon Peacocke en effet, on peut défendre résolument le Cogito tout en rejetant l’idée d’un accès privilégié à un monde intérieur. Je soutiens que l’approche rationaliste de Peacocke permet de reconstruire le Cogito d’une façon cohérente et satisfaisante, mais que s’il donne une explication particulièrement convaincante du passage de « je pense » à « j’existe », il échoue à fonder une théorie cartésienne unifiée de la connaissance de soi introspective.

A successful declaration of one’s identity in saying “ahaṃ Brahmāsmi” is a result of knowing one’s own self as indistinguishable from Brahman. The non-difference between oneself and the Brahman is one’s true identity, and it goes without saying, knowledge of one’s true identity constitutes the correct knowing of one’s own self. That the said non-difference is upheld by vedānta, and we need to put this ideal non-difference into practice is the crux of Vivekananda’s practical vedānta. Vivekananda gives certain reasons for (...) the practicability of vedānta. This paper’s part I is an exposition of Vivekananda’s practical vedānta, focussing on those reasons for practical vedānta and orienting each towards an analytical understanding. In part II, a linguistic analysis of Vivekananda’s approach to one’s identity has been carried out after introducing J. Hintikka’s interpretation of Descartes’ “I think, therefore, I am” and G. Misra’s interpretation of sat cit ānanda. The latter’s interpretation displays a positivist’s linguistic analysis of vedānta, whereas the former’s does a speech act theorist’s analysis of Descartes’ cogito principle. The present analysis indicates that practical vedānta can be read in the light of analytic philosophy and Vivekananda’s approach to one’s identity can be understood in terms of speech acts. (shrink)

When we use a directly referential expression to denote an object, do we incur an ontological commitment to that object, as Russell and Barcan Marcus held? Not according to Quine, whose regimented language has only variables as denoting expressions, but no constants to model direct reference. I make a case for a more liberal conception of ontological commitment—more wide-ranging than Quine’s—which allows for commitment to individuals, with an improved logical language of regimentation. The reason for Quine’s prohibition on commitment to (...) individuals, I argue, is that his choice of regimented language is heavily informed by his holist epistemology, in which objects are introduced via a description of their explanatory role. But non-holists can coherently attempt to commit to individuals using directly referential expressions, modelled in a formal language as constants. While holding on to the insight that a logical language is a helpful medium for ontology, I propose instead a more permissive language of regimentation, one expanded to permit the use of constants to record attempts to commit to individuals, which allows us to make sense of non-holist theories with alternative name-based or name-and-variable-based criteria of ontological commitment as well as Quinean theories.
