The purpose of this note is to present a strong form of the liar paradox. It is strong because the logical resources needed to generate the paradox are weak, in each of two senses. First, few expressive resources required: conjunction, negation, and identity. In particular, this form of the liar does not need to make any use of the conditional. Second, few inferential resources are required. These are: (i) conjunction introduction; (ii) substitution of identicals; and (iii) the inference: From ¬(p (...) ∧ p), infer ¬ p. It is, interestingly enough, also essential to the argument that the ‘strong’ form of the diagonal lemma be used: the one that delivers a term λ such that we can prove: λ = ¬ T(⌈λ⌉); rather than just a sentence Λ for which we can prove: Λ ≡ ¬T(⌈Λ⌉). The truth-theoretic principles used to generate the paradox are these: ¬(S ∧ T(⌈¬S⌉); and ¬(¬S ∧ ¬T(⌈¬S⌉). These are classically equivalent to the two directions of the T-scheme, but they are intuitively weaker. The lesson I would like to draw is: There can be no consistent solution to the Liar paradox that does not involve abandoning truth-theoretic principles that should be every bit as dear to our hearts as the T-scheme. So we shall have to learn to live with the Liar, one way or another. (shrink)

This book by Richard G. Stevens is a comprehensive introduction to the nature of political philosophy. It offers definitions of philosophy and politics, showing the tension between the two and the origin of political philosophy as a means of resolution of that tension. Plato and Aristotle are examined in order to see the search for the best political order. Inquiry is then made into political philosophy's new tension brought about by the growth of revealed religion in the Middle Ages. (...) It then examines the changes introduced by modernity and gives an overview of postmodern political thought. The book covers the most influential philosophers and directs readers to the classics of political philosophy, guiding them in studying them. It is an approachable introduction to a complex subject, not just a history of it. It is a point of entry into the subject for students and for others as well. (shrink)

Contrairement à une croyance trop répandue, le darwinisme et son prolongement au XXe siècle — le néo-darwinisme — ne portent pas sur une idée de l'évolution fondée sur la simple notion de « la survie du plus apte ». Si la théorie de la sélection naturelle est partie intégrante du néo-darwinisme, plusieurs de ses fondateurs seront en quête d'une conception beaucoup plus généreuse, pleine et compréhensive de l'évolution. En réalité, la révolution dite darwinienne s'insère au coeur d'une révolution intellectuelle beaucoup (...) plus importante : la révolution transformiste. Avant d'être des darwiniens, de dignes représentants de cette mouvance s'afficheront comme étant des transformistes. Cela signifie que, en plus des mécanismes de l'évolution biologique, d'autres éléments tout aussi cruciaux seront pris en considération`, dans l'élaboration d'une véritable synthèse évolutionniste : les rapports entre l'évolution biologique et l'évolution cosmique ; les interrogations portant sur la question d'une possible direction évolutive ; l'enseignement à tirer pour l'homme de sa place et de son rôle dans la nature. A la croisée de l'histoire, de la philosophie et de la science, cet ouvrage cherche à démontrer, à travers l'analyse des travaux de plusieurs néo-darwiniens de premier plan, que la révolution darwinienne demeurera incomplète aussi longtemps que la révolution transformiste le restera.

Øystein Linnebo has recently shown that the existence of successors cannot be proven in predicative Frege arithmetic, using Frege’s definitions of arithmetical notions. By contrast, it is shown here that the existence of successor can be proven in ramified predicative Frege arithmetic.

The 1920-1960 period saw the creation of the conditions for a unification of disciplines in the area of evolutionary biology under a limited number of theoretical prescriptions: the evolutionary synthesis. Whereas the sociological dimension of this synthesis was fairly successful, it was surprisingly loose when it came to the interpretation of the evolutionary mechanisms per se, and completely lacking at the level of the foundational epistemological and metaphysical commitments. Key figures such as Huxley, Simpson, Dobzhansky, and Rensch only paid lip (...) service to the conceptual dimension of the evolutionary synthesis, as they eventually realized that a number of evolutionary phenomena could not be explained by its narrow theoretical corpus. Apparently, the evolutionary synthesis constituted a premature event in the development of evolutionary biology. Not only are the real achievements of the evolutionary synthesis in need of reevaluation, but this reassessment also has important implications for the historiography of Darwinism and the current debates about the darwinian movement.

Gottlob Frege's Grundgesetze der Arithmetik, or Basic Laws of Arithmetic, was intended to be his magnum opus, the book in which he would finally establish his logicist philosophy of arithmetic. But because of the disaster of Russell's Paradox, which undermined Frege's proofs, the more mathematical parts of the book have rarely been read. Richard G.

In lieu of an abstract, here is a brief excerpt of the content:Pathology of the Mind: Disorder Versus DisabilityRichard G. T. Gipps (bio)Keywordsorder, disorder, ability, disability, mental illnessAlfredo Gaete (2008) describes mental disorders as impairments in intentionality, phenomenal consciousness, and intelligence that cause harm to the affected person. I found persuasive Gaete’s claim that the concept of ‘mental disorder’ is best understood as nontheoretical and nontechnical. I also find compelling his argument that a previous contribution of my own—which relied in (...) part on specifying different senses of ‘disorder’ in psychological, physiological, and social cases—was misguided. Further, his suggestion that we ought at least to attempt analysis in terms of necessary and sufficient conditions before we seek out less definitive characterizations (in terms of family resemblances) also persuades me, although I find myself less sanguine than he about the general possibility of achieving such analyses.One of Gaete’s principal claims is that mental disorder is helpfully understood in terms of an absence of a capacity—that is, as a disability. There are two related objections—or two aspects of the same objection—that I would like to offer the author with respect to this claim. These may well not be conclusive, but will I hope at least function as foils against which the author can usefully sharpen his argument. One objection suggests that there is a viable distinction between the concepts of mental disorder and mental disability, as commonly used in clinical contexts, which the account offered seems unable to respect. The second suggests that the account may not be able to theorize what is argued to be the essential contribution of the concepts of order and disorder (as opposed to ability and disability) to the everyday concept of mental disorder. Accordingly, it questions the power of a disability approach such as Gaete’s to capture the essential nature of mental disorder.In his paper, Gaete classifies mental retardation and developmental, or (what in the United Kingdom are known as) learning, disabilities (autism, etc.) as cases of mental disorder. I found this surprising because it is not common linguistic practice in the psychological circles in which I operate. It would also seem to make a nonsense of commonly accepted ideas like: “Mental disorders are more likely to occur in patients with developmental disabilities (e.g., in autism, Asperger, or Down syndrome) than in the general population.” (For an example, see Campbell and Malone [1991]). On Gaete’s classification, it would appear that people with autism eo ipso have a mental disorder, and [End Page 341] hence the commonly accepted idea would need to be interpreted as merely a statement about comorbidities of different disorders of the same general (i.e., mental) type. But that is not, I believe, how the term is commonly used, and Gaete’s suggestion must therefore be treated as revisionary rather than descriptively analytical.One way of reconstructing a rationale underlying the distinction between mental disabilities and mental disorders is as follows. A developmental disability involves a failure of (certain aspects of) the mind to grow and reach an expected level or type of organization. A mental disorder by contrast involves a disturbance or disorganization (not simply an impoverishment) within the mind at whichever level of organization it has reached. As the mind develops, and reaches new levels or types of organization, the forms which mental disorders may take accordingly change.Autism and schizophrenia provide helpful illustrations of this distinction. Autism represents a failure of (among other things) the social mind to develop in childhood. The person with moderate to severe autism may attain at best a very shaky grasp on the realities of other minds and social conventions. That is, the degree of mental structure they obtain—their social competencies or capacities—will likely remain limited. It is this fundamental deficit that marks out the disability, and not the social anxieties or other such disturbances that can beset the autistic person.Schizophrenia, by contrast, tends to occur at late adolescence, when the individual has developed higher levels of—albeit often fragile—mental structure. Yet it is not the fragility of such mental structure, but rather the disruptions that can occur within such structures as have developed, that mark them out... (shrink)

This book offers a thorough reanalysis of Charles Darwin's Origin of Species, which for many people represents the work that alone gave rise to evolutionism. Of course, scholars today know better than that. Yet, few resist the temptation of turning to the Origin in order to support it or reject it in light of their own work. Apparently, Darwin fills the mythical role of a founding figure that must either be invoked or repudiated. The book is an invitation to move (...) beyond what is currently expected of Darwin's magnum opus. Once the rhetorical varnish of Darwin's discourses is removed, one discovers a work of remarkably indecisive conclusions. The book comprises two main theses: The Origin of Species never remotely achieved the theoretical unity to which it is often credited. Rather, Darwin was overwhelmed by a host of phenomena that could not fit into his narrow conceptual framework. In the Origin of Species, Darwin failed at completing the full conversion to evolutionism. Carrying many ill-designed intellectual tools of the 17th and 18th centuries, Darwin merely promoted a special brand of evolutionism, one that prevented him from taking the decisive steps toward an open and modern evolutionism. It makes an interesting read for biologists, historians and philosophers alike. (shrink)

Originally published between 1968 and 2009, this collection of 25 pieces includes six interviews translated into English for the first time and a new transcription of a Q&A session with Baudrillard following a lecture he gave in London in 1994. The guiding theme of the collection is Baudrillard's engagement with culture. The implications of the implosion of Western culture are dissected and documented in the rich range of material included here.

When assessing a new philosophical theory of psychopathology, a first question might be: is it descriptive or revisionary in intent? Does it aim to provide reflective understanding of what is already meant by correct uses of ‘mental disorder’? Or instead to redeploy that familiar term in articulating a new concept meeting particular desiderata? Nielsen offers us an ‘enactive conceptualization’ of mental disorder, and conceptualizations are typically understood as inventive rather than descriptive. However it was not entirely clear to me, from (...) reading his text, that this was indeed his ambition. My first question for Nielsen, then, is clarificatory: does he intend his project as descriptive or revisionary?If the... (shrink)

Scaffolds are fundamental to many cellular signaling pathways. In this essay, a novel class of scaffolds are proposed, whose action bears striking resemblance to kinetic proofreading. Commonly, scaffold proteins are thought to work as tethers, bringing different components of a pathway together to improve the likelihood of their interaction. However, recent studies show that the cytoskeletal scaffold, anillin, supports contractile signaling by a novel, non‐tethering mechanism that controls the membrane dissociation kinetics of RhoA. More generally, such proof‐reading‐like scaffolds are distinguished (...) from tethers by a rare type of cooperativity, manifest as a super‐linear relationship between scaffold concentration and signaling efficiency. The evidence for this hypothesis is reviewed, its conceptual ramifications are considered, and research questions for the future are discussed. (shrink)

In this exciting new collection, a distinguished international group of philosophers contribute new essays on central issues in philosophy of language and logic, in honor of Michael Dummett, one of the most influential philosophers of the late twentieth century. The essays are focused on areas particularly associated with Professor Dummett. Five are contributions to the philosophy of language, addressing in particular the nature of truth and meaning and the relation between language and thought. Two contributors discuss time, in particular the (...) reality of the past. The last four essays focus on Frege and the philosophy of mathematics. The volume represents some of the best work in contemporary analytical philosophy. (shrink)

The paper formulates and proves a strengthening of ‘Frege’s Theorem’, which states that axioms for second-order arithmetic are derivable in second-order logic from Hume’s Principle, which itself says that the number of Fs is the same as the number ofGs just in case the Fs and Gs are equinumerous. The improvement consists in restricting this claim to finite concepts, so that nothing is claimed about the circumstances under which infinite concepts have the same number. ‘Finite Hume’s Principle’ also suffices for (...) the derivation of axioms for arithmetic and, indeed, is equivalent to a version of them, in the presence of Frege’s definitions of the primitive expressions of the language of arithmetic. The philosophical significance of this result is also discussed. (shrink)

This book prints for the first time two remarkable interlocking sequences of letters between Paris and the Netherlands: 40 letters from Gilles Ménage in Paris to Johann-Georg Grævius in Utrecht, and 30 from the printer Henrik Wetstein, in Amsterdam, to Ménage. Their principal focus is the publication of a considerable number of Ménage's works outside France, above all his monumental edition of Diogenes Laertius's Lives of the Philosophers. The letters give an engaging picture of mutual help within the community of (...) scholars, Dutch, German, English, and French, including Huguenot exiles like Le Clerc and Bayle. Ménage's are full of information from Paris; while Wetstein's, forthright and humorous, concentrate on publishing details in a sometimes stormy relationship. The great Diogenes edition encountered an extraordinary range of problems: difficulties at every stage of publication, hazardous wartime communications, and, not least, a bizarrely eccentric collaborator in Marcus Meibomius. The two correspondences provide a fascinating case-study of the practical working of international scholarly publishing in time of war, and the European network of learned correspondence in the later seventeenth century. Each letter is printed in full, accompanied by a summary, detailed commentary, and extensive annotations. (shrink)

Thirty-four states criminalize HIV in some way, whether by mandating disclosure of one’s HIV status to all sexual partners or by deeming the saliva of HIV-positive persons a “deadly weapon.” In this paper, we argue that HIV-specific criminal laws are rooted in historical prejudice against HIV-positive persons as a class. While purporting to promote public health goals, these laws instead legally sanction discrimination against a class of persons.

In The Varieties of Reference, Gareth Evans argues that the content of perceptual experience is nonconceptual, in a sense I shall explain momentarily. More recently, in his book Mind and World, John McDowell has argued that the reasons Evans gives for this claim are not compelling and, moreover, that Evans’s view is a version of “the Myth of the Given”: More precisely, Evans’s view is alleged to suffer from the same sorts of problems that plague sense-datum theories of perception. In (...) particular, McDowell argues that perceptual experience must be within “the space of reasons,” that perception must be able to give us reasons for, that is, to justify, our beliefs about the world: And, according to him, no state that does not have conceptual content can be a reason for a belief. Now, there are many ways in which Evans’s basic idea, that perceptual content is nonconceptual, might be developed; some of these, I shall argue, would be vulnerable to the objections McDowell brings against him. But I shall also argue that there is a way of developing it that is not vulnerable to these objections. (shrink)

Hauptman’s paper tells of a Mr. A, who refused exogenous treatment for the depression he felt consequent on the end of a romantic relationship, because such treatment seems to be inauthentic and despicable. It seemed this way because the depression felt like an apt response to the loss of the beloved.Like Hauptman, I have some sympathy with Mr. A’s position. To medicate away authentic emotional reactions to the trials of living is, it seems to me, to promote a form of (...) self-alienation and radical inauthenticity. Surely only the blandest form of life, which had substituted the virtues of living a truthful and meaningful life informed by those emotions that themselves embody essential information about our self in...

A chance-credence norm states how an agent's credences in propositions concerning objective chances ought to relate to her credences in other propositions. The most famous such norm is the Principal Principle (PP), due to David Lewis. However, Lewis noticed that PP is too strong when combined with many accounts of chance that attempt to reduce chance facts to non-modal facts. Those who defend such accounts of chance have offered two alternative chance-credence norms: the first is Hall's and Thau's New Principle (...) (NP); the second is Ismael's General Recipe (IP). Thus, the question arises: Should we adopt NP or IP or both? In this paper, I argue that IP has unacceptable consequences when coupled with reductionism, so we must accept NP alone. (shrink)

This is the first dictionary dedicated to the work of Jean Baudrillard. It explains and contextualises more than a hundred key concepts, terms, influences and topics within his thought. An essential reference for students and scholars of Baudrillard, it also serves as an authoritative overview of how his ideas have shaped a broad range of disciplines, from art, architecture, film and photography to sociology, philosophy, human geography, media studies and cultural studies. The entries are written by 35 leading Baudrillard specialists (...) from around the world, including Rex Butler, Mike Gane, Gary Genosko, Victoria Grace, Diane Rubenstein and Andrew Wernick.

In Mind and World, John McDowell argues against the view that perceptual representation is non-conceptual. The central worry is that this view cannot offer any reasonable account of how perception bears rationally upon belief. I argue that this worry, though sensible, can be met, if we are clear that perceptual representation is, though non-conceptual, still in some sense 'assertoric': Perception, like belief, represents things as being thus and so.
