A compartmental model is described for the spread of Gambian sleeping sickness in a spatially heterogeneous environment in which vector and human populations migrate between two "patches": the village and the plantations. The number of equilibrium points depends on two "summary parameters": gr the proportion removed among human infectives, and R0, the basic reproduction number. The origin is stable for R0 1. Control strategies are assessed by studying the mix of vector control between the two patches that bring R0 below (...) 1. The results demonstrate the importance of vector control in the plantations. For example if 20 percent of flies are in the village and the blood meal rate in the village is 10 percent, then a 20 percent added vector mortality in the village must be combined with a 9 percent added mortality in the plantations in order to bring R0 below 1. The results are quite insentive to the blood meal rate in the village. Optimal strategies (that minimize the total number of flies trapped in both patches) are briefly discussed. (shrink)

The debate on the notion of function has been historically dominated by dispositional and etiological accounts, but recently a third contender has gained prominence: the organizational account. This original theory of function is intended to offer an alternative account based on the notion of self-maintaining system. However, there is a set of cases where organizational accounts seem to generate counterintuitive results. These cases involve cross-generational traits, that is, traits that do not contribute in any relevant way to the self-maintenance of (...) the organism carrying them, but instead have very important effects on organisms that belong to the next generation. We argue that any plausible solution to the problem of cross-generational traits shows that the organizational account just is a version of the etiological theory and, furthermore, that it does not provide any substantive advantage over standard etiological theories of function.

Some mathematical proofs explain why the theorems they prove hold. This paper identifies several challenges for any counterfactual account of explanation in mathematics (that is, any account according to which an explanatory proof reveals how the explanandum would have been different, had facts in the explanans been different). The paper presumes that countermathematicals can be nontrivial. It argues that nevertheless, a counterfactual account portrays explanatory power as too easy to achieve, does not capture explanatory asymmetry, and fails to specify why (...) certain proofs are explanatory and others are not. Greater informativeness about counterfactual dependence can even yield less explanatory power. (shrink)

Why do forces compose according to the parallelogram of forces? This question has been controversial; it is one episode in a longstanding, fundamental dispute regarding which facts are not to be explained dynamically. If the parallelogram law is explained statically, then the laws of statics are separate from and “transcend” the laws of dynamics. Alternatively, if the parallelogram law is explained dynamically, then statical laws become mere corollaries to the dynamical laws. I shall attempt to trace the history of this (...) controversy in order to identify what it would be for one or the other of these rival views to be correct. I shall argue that various familiar accounts of natural law not only make it difficult to see what the point of this dispute could have been, but also improperly foreclose some serious scientific options. I will sketch an alternative account of laws that helps us to understand what this dispute was all about. (shrink)

Street’s (Philos Stud 127(1):109–166, 2006) Darwinian Dilemma purports to show that evolutionary considerations are in tension with realist theories of value, which include moral realism. According to this argument, moral realism can only be defended by assuming an implausible tracking relation between moral attitudes and moral facts. In this essay, I argue that this tracking relation is not as implausible as most people have assumed by showing that the three main objections against it are flawed. Since this is a key (...) premise in the reasoning, I conclude that the Darwinian Dilemma against moral realism can be resisted. (shrink)

In recent years, a number of cultural theorists have made important contributions to the study of the body’s surface. Despite their importance, however, none of these contributions provides us with a systematic framework for understanding why the body’s surface — its skin — matters to the extent that it does. In this article, I seek to provide such a framework and, in doing so, to shed light on why the skin and the self seem to share a special and sometimes (...) strained relationship. To this end, I will present a critical introduction to the work of two contemporary Anglo-American psychoanalysts: Esther Bick and Thomas Ogden. Throughout this introduction, I will show how both Bick and Ogden — despite the fact that they are almost completely unknown outside clinical circles — offer up a host of conceptual tools that could prove useful to cultural theorists interested in making sense of the relationship between the skin and the self.

Myrvold (2003) has proposed an attractive Bayesian account of why theories that unify phenomena tend to derive greater epistemic support from those phenomena than do theories that fail to unify them. It is argued, however, that "unification" in Myrvold's sense is both too easy and too difficult for theories to achieve. Myrvold's account fails to capture what it is that makes unification sometimes count in a theory's favor.

Explanation in mathematics has recently attracted increased attention from philosophers. The central issue is taken to be how to distinguish between two types of mathematical proofs: those that explain why what they prove is true and those that merely prove theorems without explaining why they are true. This way of framing the issue neglects the possibility of mathematical explanations that are not proofs at all. This paper addresses what it would take for a non-proof to explain. The paper focuses on (...) a particular example of an explanatory non-proof: an argument that mathematicians regard as explaining why a given theorem holds regarding the derivative of an infinite sum of differentiable functions. The paper contrasts this explanatory non-proof with various non-explanatory proofs of the same theorem. The paper offers an account of what makes the given non-proof explanatory. This account is motivated by investigating the difficulties that arise when we try to extend Mark Steiner’s influential account of explanatory proofs to cover this explanatory non-proof. (shrink)

Building on the notational principles of C. S. Peirce’s graphical logic, Pietarinen has tried to develop a propositional logic unfolding in the medium of sound. Apart from its intrinsic interest, this project serves as a concrete test of logic’s range. However, I argue that Pietarinen’s inaugural proposal, while promising, has an important shortcoming, since it cannot portray double-negation without thereby portraying a contradiction.

This paper argues that there is a conflict between two theses held by John McDowell, namely i) the claim that we are under a standing obligation to revise our beliefs if reflection demands it; and ii) the view that veridical experience is a mode of direct access to the world. Since puts no bounds on what would constitute reasonable doubt, it invites skeptical concerns which overthrow. Conversely, since says that there are some experiences which we are entitled to trust, it (...) undermines the prescriptive scope of. Drawing on C. S. Peirce's distinction between genuine and contrived doubt, I maintain that critical revisions of beliefs should be triggered only by unwanted disruptions of habits, thereby restoring unity between McDowell's two theses.

In the course of legal reasoning—whether for purposes of deciding an issue, justifying a decision, predicting how an issue will be decided, or arguing for how it should be decided—one often is required to reach conclusions based on a balance of reasons that is not straightforwardly reducible to the application of rules. Recent AI and Law work has modeled reason-balancing, both within and across cases, with set-theoretic and rule- or value-ordering approaches. This article explores a way to model balancing in (...) quantitative terms that may yield new questions, insights, and tools. (shrink)

C. S. Peirce introduced the term “icon” for sign-vehicles that signify their objects in virtue of some shared quality. This qualitative kinship, however, threatens to collapse the relata of the sign into one and the same thing. Accordingly, the late medieval philosopher of signs John Poinsot held that, “no matter how perfect, a concept [...] always retains a distinction, therefore, between the thing signified and itself signifying.” Poinsot is touted by his present-day advocates as a realist, but I believe that, (...) judged by realist standards, his requirement of minimal dissimilarity backfires. Poinsot thinks that, in analyzing the sign, we should stop before a full merger between sign-vehicle and object is reached. Peirce, by contrast, saw good reason to push the analysis all the way down to one isolated quality. Because such a qualitative merger can lend support to realism, I favour Peirce’s stance. (shrink)

This essay argues that acknowledging the existence of mind-independent facts is a matter of vital importance, in that acquiescence before the layout of the world is something demanded of knowing agents from the most elementary empirical deliverance to the most abstract construct. Building on the idea that normativity requires the presence of more than one option to choose from, the essay shows how the cessation of one's life is the disjunctive alternative of any experiential episode. This much has been missed, (...) it argues, because of a generalized failure to appreciate how even the simplest atomic contents embroil their subjects in acts of assent. Its account thus casts a new light on relativism and skepticism, revealing them to be provisional luxuries supported only by the cognitive labor of others. (shrink)

Deliberation is often seen as the site of human freedom, but the binding power of rationality seems to imply that deliberation is, in its own way, a deterministic process. If one knows the starting preferences and circumstances of an agent, then, assuming that the agent is rational and that those preferences and circumstances don’t change, one should be in a position to predict what the agent will decide. However, given that an agent could conceivably confront equally attractive alternatives, it is (...) an open question whether rational choice theory can ever eliminate indeterminacy. The clearest support for such a limitation comes from the “Buridan’s ass” scenario, where an agent is confronted with two (or more) equally attractive/unattractive options. Does rationality by itself have the resources needed to prevent such paralysis of action? Those who cannot accept the idea of decisional impotence devise various ways to avoid it: postulating a neutral valence, tipping the utilities, positing sub-personal influences, and bunching the options. I argue that each of these responses is either unwarranted or flawed. All parties to the debate agree that, factually, paralysis of action is not a pervasive phenomenon. This is either because (i) the utilities one assigns to two or more options can never be balanced or because (ii) thanks to some non-rational faculty (say, the will), we would not be stuck even if those utilities were perfectly counterpoised. By looking critically at four untenable responses, I aim to show that (i) is often just a dogma and (ii) is by no means a silly position. (shrink)

The present essay on the being of the sensible investigates the individuation of intensity differentials. This is Deleuze's theme in the fifth chapter of Difference and Repetition, where he places individuation in the context of his ‘transcendental empiricism’. The mechanisms of subjectivation are conceived as spatially-temporally determined actualisations (of the virtual) whose implicit intensity relations are neither accessible empirically nor are they governed by transcendental conditions (in the conventional sense). Central to the discussion is the distinction, stemming from Kant, between (...) intensive and extensive magnitudes. (shrink)

In an attempt to start rectifying a lamentable disparity in scholarship, we evince fruitful points of similarity and difference in the ideas of Simone de Beauvoir and Ayn Rand, paying particular attention to their views on long-term projects. Endorsing what might be called an “Ethic of Resolve,” Rand praises those who undertake sustained goal-directed actions such as careers. Beauvoir, however, endorses an “Ethic of Ambiguity” that makes her more skeptical about the prospects of carrying out lifelong projects without deluding oneself. (...) Our study teases apart the strengths and drawbacks of these views. (shrink)

In order to be able to provide informed, effective and responsive mental health care and to do so in an evidence‐based, collaborative and recovery‐focused way with those who use mental health services, there is a recognition of the need for mental health professionals to possess sophisticated critical thinking capabilities. This article will therefore propose that such capabilities can be productively situated within the context of the work of the French philosopher Michel Foucault, one of the most challenging, innovative and influential (...) thinkers of the 20th century. However, rather than focusing exclusively upon the content of Foucault's work, it will be suggested that it is possible to discern a general methodological approach across that work, a methodological approach that he refers to as “the history of the present.” In doing so, Foucault's history of the present can be understood as a productive, albeit provisional, framework in which to orientate the purpose and process of critical thinking for mental health professionals by emphasizing the need to both historicize and politicize the theoretical perspectives and therapeutic practices that characterize contemporary mental health care.

Glymour, Scheines, Spirtes, and Kelly argue for ‘Spearman's Principle’: one should (ceteris paribus) favour the theory whose ‘free parameters’ need assume no particular values for the theory to save the ‘constraints’ holding of the phenomena. I argue that the rationale they give for Spearman's Principle fails, but that (contra Cartwright) Spearman's Principle cannot be made to favour either of two theories depending on how they are expressed. I examine how one must motivate the demand for a scientific explanation of a (...) parameter's value and how one justifies believing that a constraint should be explained independent of any parameter's particular value.

"We are omniscient but confused," says Leibniz. He also says that we live in the best of all possible worlds, yet do not causally interact. So what are we? Leibniz is known for many things, including the ideality of space and time, calculus, plans for a universal language, theodicy, and ecumenism. But he is not known for his ideas on the self and personal identity. This book shows that Leibniz offers an original, internally coherent theory of personal identity, a theory (...) that stands on its own even next to Locke's contemporaneous and more famous version. This book will appeal not only to students of Leibniz's thought but also to philosophers and psychologists interested in methodological problems in understanding or formulating theories of self and personal identity.

Leibniz defends concurrentism, the view that both God and created substances are causally responsible for changes in the states of created substances. Interpretive problems, however, arise in determining just what causal role each plays. Some recent work has been revisionist, greatly downplaying the causal role played by created substances—arguing instead that according to Leibniz only God has productive causal power. Though bearing some causal responsibility for changes in their perceptual states, created substances are not efficient causes of such changes. This (...) paper argues against such revisionism; not only was Leibniz a consistent advocate of concurrentism (at least in his “mature” years), but also his account of concurrentism involves both God and created substances asefficient causes of the changes in the states of created substances.

This chapter begins with an exposition of Foucault's genealogical account of critique as an untheorized attitude and mode of existence, that of being critical. Foucault finds the sources of philosophical critique in practices of resistance to politicized forms of pastoral power transposed from Hebraic and Christian traditions at the time of the Protestant Reformation. The next section explores Foucault's identification of the first theoretical formulation of this attitude of being critical in Kant's essay “ What is Enlightenment?”. The ensuing section (...) sketches Foucault's reading of Kant's piece, with an eye to the distinction between the transcendental version of critique practiced in the three Critiques, and critique as Enlightenment, the attitude characterized by the will not to be poorly or excessively governed. Finally, Foucault's analysis of modernity is presented as a model of practicing the self, a “limit attitude” emblematic of the exercise of freedom. (shrink)

The physics of color and the psychology of color naming are not isomorphic. Physically, the spectrum is continuous with regard to wavelength colors change qualitatively from one wavelength region to another. The psychological characterization of hue that characterizes color vision has been revealed in a series of modern psychophysical studies with human adults and infants and with various infrahuman species, including vertebrates and invertebrates. These biopsychological data supplant an older psycholinguistic and anthropological literature that posited that language and culture alone (...) influence perceptual processes; language and culture may modify color naming beyond basic categorizations.

De 1950 à 1955, le psychologue et épistémologue suisse Jean Piaget s’attelle à la création d’un nouveau lieu de savoir à Genève, le Centre International d’Épistémologie Génétique. Ce Centre fait aboutir un projet de jeunesse de Piaget, dont les fondements théoriques sont donnés dans son ouvrage de 1950 en trois volumes, l’Introduction à l’épistémologie génétique. Mais il y a loin de la théorie à la réalisation pratique. Pour cela, pris dans un mouvement allant de Genève vers l’étranger, dès 1952, Piaget (...) voyage dans toute l’Europe tant pour y présenter ses travaux et son projet que pour se lier avec de nombreux savants de toutes disciplines. Lors de ces voyages, il explore de nombreux modèles de centres et de regroupements d’acteurs en philosophie des sciences, sciences humaines et épistémologie, à Paris, Zurich, Manchester, Milan, Oslo, Amsterdam, Bruxelles et ailleurs. Quatre axes géographiques vont devenir déterminants (Paris, Manchester, Bruxelles, Amsterdam) pour fournir les principaux contingents d’acteurs qui interviendront au Centre durant sa première décennie. Piaget a également pris soin de s’assurer le soutien financier de la Fondation Rockefeller à New York, d’une part pour ses premières explorations et d’autre part pour l’ouverture du Centre en octobre 1955. L’article examine ainsi les conditions de création d’un lieu du savoir durant les premiers temps de la guerre froide dans ses relations avec les circulations scientifiques, et la genèse d’une nouvelle centralité valide pour l’épistémologie mise en pratique comme discipline scientifique.

Il est proposé une réflexion épistémologique sur la posture que l'historien des sciences humaines peut adopter vis-à-vis de ses objets d'investigation. La théorie du « criminel-né » de Cesare Lombroso, produite dans le dernier tiers du x1xe siècle est prise ici comme exemple et support pour la discussion parce qu'elle apparaît comme un cas limite, presque caricatural, tant par sa formulation initiale que par son traitement dans la mémoire disciplinaire. Les approches normatives ou « présentistes » ne pouvant rendre compte (...) de la logique du discours de Lombroso que sur le mode de la dénégation, il a semblé préférable - sans qu'il soit nécessaire de devenir lombrosien - de suivre un autre fil directeur. On suggère de substituer à une posture épistémologique présentiste les concepts de « rationalité contextuelle » et de « présupposé cognitif». Ces concepts, combinés à une plus grande sensibilité aux différentes durées pourraient initier une approche qui serait à la fois plus spécifiquement historique et ouverte aux apports des autres sciences humaines.
