We argue that a fashionable interpretation of the theory of natural selection as a claim exclusively about populations is mistaken. The interpretation rests on adopting an analysis of fitness as a probabilistic propensity which cannot be substantiated, draws parallels with thermodynamics which are without foundations, and fails to do justice to the fundamental distinction between drift and selection. This distinction requires a notion of fitness as a pairwise comparison between individuals taken two at a time, and so vitiates the interpretation (...) of the theory as one about populations exclusively.

For many epistemologists and normativity theorists, epistemic norms necessarily entail normative reasons. Why or in virtue of what do epistemic norms have this necessary normative authority? According to what I call epistemic constitutivism, it is ultimately because belief constitutively aims at truth. In this paper, I examine various versions of the aim of belief thesis and argue that none of them can plausibly ground the normative authority of epistemic norms. I conclude that epistemic constitutivism is not a promising strategy for (...) grounding epistemic normativity. (shrink)

According to moral error theorists, moral claims necessarily represent categorically or robustly normative facts. But since there are no such facts, moral thought and discourse are systematically mistaken. One widely discussed objection to the moral error theory is that it cannot be true because it leads to an epistemic error theory. We argue that this objection is mistaken. Objectors may be right that the epistemic error theory is untenable. We also agree with epistemic realists that our epistemological claims are not (...) systematically in error. However, this is not because there are robustly normative facts, but rather because the truth of our epistemic claims doesn’t turn on whether there are such facts. Epistemic facts, we argue, are not robustly or categorically normative. Moral error theorists should therefore respond to the objection that their view does not commit them to the epistemic error theory. (shrink)

What is the source of epistemic normativity? In virtue of what do epistemic norms have categorical normative authority? According to epistemic teleologism, epistemic normativity comes from value. Epistemic norms have categorical authority because conforming to them is necessarily good in some relevant sense. In this article, I argue that epistemic teleologism should be rejected. The problem, I argue, is that there is no relevant sense in which it is always good to believe in accordance with epistemic norms, including in cases (...) where the matter at hand is completely trivial. Therefore, if epistemology is normative, its normativity won't come from value. (shrink)

According to epistemic instrumentalism, epistemic normativity arises from and depends on facts about our ends. On that view, a consideration C is an epistemic reason for a subject S to Φ only if Φ-ing would promote an end that S has. However, according to the Too Few Epistemic Reasons objection, this cannot be correct since there are cases in which, intuitively, C is an epistemic reason for S to Φ even though Φ-ing would not promote any of S’s ends. After (...) clarifying both EI and the Too Few Epistemic Reasons objection, I examine three major instrumentalist replies and argue that none of them is satisfactory. I end by briefly sketching a fourth possible response, which is, I suggest, more promising than the other three. (shrink)

Epistemic instrumentalism views epistemic norms and epistemic normativity as essentially involving the instrumental relation between means and ends. It construes notions like epistemic normativity, norms, and rationality, as forms of instrumental or means-end normativity, norms, and rationality. I do two main things in this paper. In part 1, I argue that there is an under-appreciated distinction between two independent types of epistemic instrumentalism. These are instrumentalism about epistemic norms and instrumentalism about epistemic normativity. In part 2, I argue that this (...) under-appreciated distinction matters for the debate surrounding the plausibility of EI. Specifically, whether we interpret EI as norm-EI or as source-EI matters for the widely discussed universality or categoricity objection to EI, and for two important motivations for adopting EI, namely naturalism and the practical utility of epistemic norms. I will then conclude by drawing some lessons for epistemic instrumentalism going forward. (shrink)

One of intuitions driving the acceptance of a neat structured tree of life is the assumption that organisms and the lineages they form have somewhat stable spatial and temporal boundaries. The phenomenon of symbiosis shows us that such ‘fixist’ assumptions does not correspond to how the natural world actually works. The implications of lateral gene transfer (LGT) have been discussed elsewhere; I wish to stress a related point. I will focus on lateral function transfer (LFT) and will argue, using examples (...) of what many would call ‘superorganisms’, that the emergence of symbiotic individuals revives the importance of functional and adaptationist thinking in how we conceptualize the lineages of biological individuals. The consequence of the argument is that, if we really want to hold onto tree of life thinking, we had better accept that new saplings appear and disappear all the time. (shrink)

Our intuitive assumption that only organisms are the real individuals in the natural world is at odds with developments in cell biology, ecology, genetics, evolutionary biology, and other fields. Although organisms have served for centuries as nature’s paradigmatic individuals, science suggests that organisms are only one of the many ways in which the natural world could be organized. When living beings work together—as in ant colonies, beehives, and bacteria-metazoan symbiosis—new collective individuals can emerge. In this book, leading scholars consider the (...) biological and philosophical implications of the emergence of these new collective individuals from associations of living beings. The topics they consider range from metaphysical issues to biological research on natural selection, sociobiology, and symbiosis. -/- The contributors investigate individuality and its relationship to evolution and the specific concept of organism; the tension between group evolution and individual adaptation; and the structure of collective individuals and the extent to which they can be defined by the same concept of individuality. These new perspectives on evolved individuality should trigger important revisions to both philosophical and biological conceptions of the individual. -/- Contributors: Frédéric Bouchard, Ellen Clarke, Jennifer Fewell, Andrew Gardner, Peter Godfrey-Smith, Charles J.

The dominant meta-theories in contemporary sociolinguistics include interactionism, social constructivism, poststructuralism and similarly relativist, anti-realist approaches (hereby grouped within the broader category of interpretivism). This paper argues that anti-scientific, anti-realist tendencies in contemporary sociolinguistics are ill-justified, confuse science with positivism, and weaken sociolinguists' necessary commitment to objectivity (hereby understood as commitment by scientists to explain the ontological order, or what exists regardless of whether it is known by people). The anti-realism in interpretivist sociolinguistics also considerably diminishes the ability of sociolinguists (...) to, for example, make ontological claims about language and its users, study phenomena including linguistic hierarchies and linguistic/social oppression as systems, and develop robust and effective strategies for critical engagement and social emancipation. By reaffirming sociolinguistics as part of the scientific project, and by reframing sociolinguistics within critical realism (CR), this paper offers conceptual alternatives to the dominant interpretivist tendencies in contemporary sociolinguistics.

The general principle of epistemic closure stipulates that epistemic properties are transmissible through logical means. According to this principle, an epistemic operator, say ε, should satisfy any valid scheme of inference, such as: if ε(p entails q), then ε(p) entails ε(q). The principle of epistemic closure under known entailment (ECKE), a particular instance of epistemic closure, has received a good deal of attention since the last thirty years or so. ECKE states that: if one knows that p entails q, and (...) she knows that p, then she knows that q. It is widely accepted that ECKE constitutes an important piece of the skeptical argument, but the acceptance of an unrestricted version of ECKE is still a matter of debate. On the side of the defenders of ECKE, one finds Stine (1976), Brueckner (1985), Vogel (1990), and Feldman (1995). Others proposed a refutation or a limitation of the principle, like Dretske (1970), Nozick (1981), Hales (1995), Williams (1996), and Sosa (1999). As it turns out, the relevant alternatives view (RAV) elaborated by Dretske, which restricts the scope of ECKE, has been discussed extensively and acknowledged as one of the most important contributions. There is nonetheless a major unsolved difficulty pertaining to Dretske-RAV: the notion of relevant alternatives is defined in such a way that it is bounded by counterfactual possibilities. This ontological import leaves open the door to the skeptic. Some have tried to give more precision to this notion, like Stine (1976), who appealed to a Gricean approach to define relevant alternatives in conversational contexts. My proposal is in accordance with the gist of Dretske’s strategy, i.e. to restrict the validity of ECKE, and I claim that in order to escape the difficulties inherent to RAV one has to introduce a more robust notion, the notion of epistemic context. Epistemic contexts are a subclass of propositional contexts. In that perspective, the closure property is expressed in terms of a property of a relation between epistemic contexts. ECKE holds when and only when either the epistemic context of the premisses is the same as the epistemic context of the conclusion, or the epistemic context change between the premisses and the conclusion is permissible. Permissibility of epistemic context change is a function of consistency. By means of this epistemic context approach, I will show that: (1) epistemic contexts are defined by basic propositions (unchallenged justified beliefs), (2) ECKE holds only under very specific constraints, and (3) the skeptical argument involves a non-permissible change of epistemic context and, by the same token, cannot rely upon ECKE.

Maine de Biran passe à raison pour avoir rénové l'empirisme. Mais il semble qu'on n'ait pas toujours aperçu à quelle distance il a porté de son origine la méthode issue de Locke et de Condillac. Nous voudrions montrer ici comment il a pu infléchir la tradition empiriste dans un sens complètement opposé aux doctrines de ses fondateurs, comment il en a pu tirer une anthropologie tout à fait nouvelle, où l'homme n'apparaissait plus comme un élément de la nature, non plus (...) d'ailleurs que de la pensée, mais comme le principe absolu de tout ce qui est susceptible d'exister pour lui. Nous laisserons de côté le problème purement historique qu'a pu poser l'évolution personnelle de l'auteur par rapport à sa propre philosophic, et qui s'est notamment manifesté par l'abandon de la morale stoïcienne dans la dernière période de sa vie, de même que par la conversion tardive à certaines thèses, platoniciennes et substantialistes, sur la nature du moi. Ce qui sera examiné, c'est le biranisme tel qu'il fut, tel qu'il commença de se constituer, aux alentours de 1799, avec le premier Mémoire sur l'habitude. (shrink)

L'histoire de la rhétorique s'apparente à une peau de chagrin: d'une préoccupation pour les mots et les idées en général, elle a progressivement mis l'accent sur les mots, puis sur les tropes et figures, puis sur la métaphore et la métonymie, puis sur la seule métaphore. Mais l'intérêt pour les mots a refait surface dans des disciplines comme la linguistique et la stylistique. Et l'intérêt pour les idées caractérise l'oeuvre de Ch. Perelman, comme en témoigne, entre autres, son Traité de (...) l'argumentation. On soutient que celui-ci s'inscrit dans le champ d'une théorie générale des discours. (shrink)

Ecological fitness has been suggested to provide a unifying definition of fitness. However, a metric for this notion of fitness was in most cases unavailable except by proxy with differential reproductive success. In this article, I show how differential persistence of lineages can be used as a way to assess ecological fitness. This view is inspired by a better understanding of the evolution of some clonal plants, colonial organisms, and ecosystems. Differential persistence shows the limitation of an ensemblist noncausal understanding (...) of evolution. Causal explanations are necessary to understand the evolution by natural selection of these biological systems. †To contact the author write to: Department of Philosophy, University of Montreal, P.O.

Epistemology is widely seen as a normative discipline like ethics. Just like moral facts, epistemic facts – i.e. facts about our beliefs’ epistemic justification, rationality, reasonableness, correctness, warrant, and the like – are standardly viewed as normative facts. Yet, whereas many philosophers have rejected the existence of moral facts, few have raised similar doubts about the existence of epistemic facts. In recent years however, several metaethicists and epistemologists have rejected this Janus-faced or dual stance towards the existence of moral and (...) epistemic facts. As recent developments in metaethics and normativity theory have made clear, objections to the existence of moral facts really are metanormative objections that target the existence of normative facts more generally. But since epistemic facts are no less normative than moral facts, the argument goes, the existence of the former is equally threatened by metaethical objections. In this thesis, I argue that this rejection of the dual stance fails because epistemic facts are not normative facts. Although they imply norms, they do not imply genuine normativity since the epistemic norms of belief that they imply lack necessary normative authority or force. Unlike moral norms and just like e.g. norms of etiquette and the law, there is not automatically a normative reason to conform to epistemic norms. Therefore, even if metaethical objections target all normative facts, it does not follow that they also target epistemic facts. I offer a two-part abductive argument in favour of that conclusion. First, I argue that epistemic facts lack five commonly cited features of normative facts (but not of merely norm-implying facts). Then, I argue that this is best explained by the thesis that epistemic facts are merely norm-implying and not genuinely normative. I end by exploring the potential consequences of this conclusion for epistemology and metaethics. (shrink)

Given the complexity of most phenomena, we have to delegate much epistemic work to other knowers and we must find reasons for relying on these specific knowers and not others. In our societies, these other knowers are often called experts and we rely on their epistemic authority more and more. For many complex phenomena such as climate change, genetically modified crops, and immunization, the experts that are called upon are scientific experts. For that reason, finding good reasons and justification for (...) deferring to their knowledge is of paramount societal importance. As we shall see, many have analyzed this epistemic dependence on scientific experts and have tried to show in what contexts are there good... (shrink)

According to epistemic deontologism, attributions of epistemic justification are deontic claims about what we ought to believe. One of the most prominent objections to this conception, due mainly to William P. Alston, is that the principle that ‘ought’ implies ‘can’ rules out deontologism because our beliefs are not under our voluntary control. In this paper, I offer a partial defense of Alston’s critique of deontologism. While Alston is right that OIC rules out epistemic deontologism, appealing to doxastic involuntarism is not (...) necessary for generating that tension. Deontologists would still have a problem with OIC if doxastic voluntarism turned out to be true or if deontologism did not require voluntarism. This is because, in short, epistemic justification does not imply ‘can’. If, as deontologists maintain, epistemic justification implies ‘oughts’, then epistemic justification must also imply ‘can’ given OIC. But since epistemic justification does not imply ‘can’, OIC dictates that we reject deontologism. I end by exploring the possible consequences of this incompatibility between OIC and deontologism. My conclusion is that at least one of the following claims must be true. Either ‘ought’ does not imply ‘can’, attributions of epistemic justification are not deontic claims, or epistemic claims lack necessary or categorical normative authority. (shrink)

Building upon a non-standard understanding of evolutionary process focusing on variation and persistence, I will argue that communities and ecosystems can evolve by natural selection as emergent individuals. Evolutionary biology has relied ever increasingly on the modeling of population dynamics. Most have taken for granted that we all agree on what is a population. Recent work has reexamined this perceived consensus. I will argue that there are good reasons to restrict the term “population” to collections of monophyletically related replicators and (...) interactors, which explains why many existing models in population biology exclude by definition many genuine evolving biological individuals such as communities and ecosystems. By studying a case of community evolution (a symbiotic termite–fungus community), we will see that it is variation that is important to evolutionary processes, not populations. Variation within a population is only one of many types of variation that can lead to evolution by natural selection. The upshot of focusing on variation is that cases of community and ecosystem adaptive change become tractable in evolutionary terms. I will show that complex emergent individuals such as communities and ecosystems cannot be fully accommodated by conventional population/reproduction models but can be accommodated by variation/persistence models.

Martial Gueroult donna un cours au Collège de France sur la Critique de la raison pure de Kant lors de l’année 1957-1958, qui est à ce jour inédit. Le texte qui est présenté ici est l’édition d’une des leçons portant sur la différence entre les deux versions de la déduction transcendantale des catégories. Gueroult y aborde une question classique du commentaire, celle de savoir si la deuxième édition de la Critique a renié la doctrine de la première version. Contre (...) l’interprétation de Herman Jan de Vleeschauwer, Gueroult défend que l’effort de clarification de la déduction, non moins que le souci d’écarter une lecture psychologisante des facultés, ont conduit Kant à emprunter un unique chemin de la déduction des catégories : de haut en bas.

This article addresses the conditions that are necessary for non-Indigenous people to learn from Indigenous people, more specifically from women and feminists. As non-Indigenous scholars, we first explore the challenges of epistemic dialogue through the example of Traditional Ecological Knowledge. From there, through the concept of mastery, we examine the social and ontological conditions under which settler subjectivities develop. As demonstrated by Julietta Singh and Val Plumwood, the logic of mastery—which has legitimated the oppression and exploitation of Indigenous peoples—has been (...) reproduced in academia, leaving almost no room for Indigenous knowledge and epistemes. In the same vein, Sámi scholar Rauna Kuokkanen reclaims and suggests the logic of the gift as a means to render academia more hospitable to Indigenous peoples and epistemes. In our view, reclaim as a concept-practice is a promising way to disrupt colonial, racist, and sexist power relations. Thus, we in turn propose to reclaim vulnerability as defined by Judith Butler in order to deconstruct masterful settler subjectivities and reconstruct relational ones instead. As theorized by Erinn Gilson, we propose epistemic vulnerability to imagine the conditions of our learning from Indigenous peoples and philosophies. (shrink)

Récusant l'opposition de Ricoeur entre la compréhension des structures (imputée à Lévi-Strauss) et l'intelligence herméneutique (qu'il promeut lui-même), ainsi que l'assimilation de la première à la science et de la seconde à la philosophie, cet article montre que le structuralisme n'est ni science ni philosophie mais méthode, et qu'en tant que tel il peut être assumé autant par la science que par la philosophie. Il le montre à partir de l'exemple du mythe d'Oedipe, analysé successivement selon divers points de vue: (...) anthropologique (Lévi-Strauss), psychanalytique (Freud), "poétique" (c'est-à-dire relevant de la théorie littéraire) et philosophique. Il le montre ensuite en appliquant la méthode à un discours philosophique particulier, celui de Platon, au niveau d'un mythe raconté dans le "Gorgias"; puis à celui de la section du "Phèdre" opposant rhétorique et philosophie; et enfin à celui du corpus intégral de l'esthétique platonicienne.

Entre herméneutique et grammatologie, entre Gadamer et Derrida, il y aurait une profonde incompatibilité. Insurmontable? Les deux camps ont au moins en commun de réfléchir sur les conditions de possibilité du discours philosophique.Mais, en définitive, il faudrait dépasser ces deux approches au profit d'une nouvelle époque de la philosophie s'obligeant à approfondir le sens de la différence et à "retrouver à nouveaux frais la question de l'essence".

Peu de textes de Pascal semblent relever de l'expérience ou du discours mystique. Outre le Mémorial, qui garde mémoire d'une expérience de Dieu sur une feuille de papier, outre la Prière pour demander à Dieu le bon usage des maladies, certaines lettres à Mlle de Roannez contiennent des conseils pour se rapprocher de Dieu, et d'autres lettres spirituelles, comme celle écrite après la mort de son père, traitent de l'attitude du chrétien face à la mort. L'Ecrit sur la conversion du (...) pécheur nous livre les difficultés de l'homme à la recherche de Dieu. Cependant, malgré la pauvreté quantitative des textes traitant assez clairement de la mystique, il nous est apparu qu'elle constitue la clé de voûte de l'édifice pascalien, sans laquelle l'oeuvre de Pascal ne fait pas sens. A partir de ce point ultime et transcendant, expliqué en partie par le contexte familial et social de Pascal, on peut relire et comprendre sa démarche scientifique, et la relation entretenue avec la Bible. Ainsi nous proposons une relecture de l'intégralité de l'oeuvre pascalienne, en la replaçant dans l'histoire de la mystique judéo-chrétienne, et en mettant notamment en relief la façon dont Pascal s'est approprié l'esprit et la mystique bibliques, dans une tradition où l'influence du dualisme platonicien n'est pas étrangère. La mystique pascalienne se définit ainsi comme le désir d'une union à Dieu, médiatisée par la figure du Christ, et il en résulte une relation de chaque instant, où l'homme se sent transformé, déifié, dans un sentiment de joie.

According to the deontological conception of epistemic justification, a belief is justified when it is our obligation or duty as rational creatures to believe it. However, this view faces an important objection according to which we cannot have such epistemic obligations since our beliefs are never under our voluntary control. One possible strategy against this argument is to show that we do have voluntary control over some of our beliefs, and that we therefore have epistemic obligations. This is what I (...) call the voluntarist strategy. I examine it and argue that it is not promising. I show how the voluntarist attempts of Carl Ginet and Brian Weatherson fail, and conclude that it would be more fruitful for deontologists to look for a different strategy. (shrink)

We argue that ecology in general and biodiversity and ecosystem function research in particular need an understanding of functions which is both ahistorical and evolutionarily grounded. A natural candidate in this context is Bigelow and Pargetter’s evolutionary forward-looking account which, like the causal role account, assigns functions to parts of integrated systems regardless of their past history, but supplements this with an evolutionary dimension that relates functions to their bearers’ ability to thrive and perpetuate themselves. While Bigelow and Pargetter’s account (...) focused on functional organization at the level of organisms, we argue that such an account can be extended to functional organization at the community and ecosystem levels in a way that broadens the scope of the reconciliation between ecosystem ecology and evolutionary biology envisioned by many BEF researchers. By linking an evolutionary forward-looking account of functions to the persistence-based understanding of evolution defended by Bouchard and others, and to the theoretical research on complex adaptive systems, we argue that ecosystems, by forming more or less resilient assemblages, can evolve even while they do not reproduce and form lineages. We thus propose a Persistence Enhancing Propensity account of role functions in ecology to account for this overlap of evolutionary and ecological processes. (shrink)

According to the age-of-acquisition hypothesis, words acquired early in life are processed faster and more accurately than words acquired later. Connectionist models have begun to explore the influence of the age/order of acquisition of items (and also their frequency of encounter). This study attempts to reconcile two different methodological and theoretical approaches (proposed by Lambon Ralph & Ehsan, 2006 and Zevin & Seidenberg, 2002) to age-limited learning effects. The current simulations extend the findings reported by Zevin and Seidenberg (2002) that (...) have shown that frequency trajectories (FTs) have limited and specific effects on word-reading tasks. Using the methodological framework proposed by Lambon Ralph and Ehsan (2006), which makes it possible to compare word-reading and picture-naming tasks in connectionist networks, we were able to show that FT has a considerable influence on age-limited learning effects in a picture naming task. The findings show that when the input–output mappings are arbitrary (simulating picture naming tasks), the links formed by the network become entrenched as a result of early experience and that subsequent variations in frequency of exposure of the items have only a minor impact. In contrast, when the mappings between input-output are quasi-systematic or systematic (simulating word-reading tasks), the training of new items was generalized and resulted in the suppression of age-limited learning effects. At a theoretical level, we suggest that FT, which simultaneously takes account of time and the level of exposure across time, represents a more precise and modulated measure compared with the order of introduction of the items and may lead to innovative hypotheses in the field of age-limited learning effects.

ABSTRACT According to G.E. Moore’s ‘Open Question’ argument, moral facts cannot be reduced or analyzed in non-normative natural terms. Does the OQA apply equally in the epistemic domain? Does Moore’s argument have the same force against reductionist accounts of epistemic facts and concepts? In a recent article, Daniel Greco has argued that it does. According to Greco, an epistemological version of the OQA is just as promising as its moral cousin, because the relevant questions in epistemology are just as ‘open’ (...) as those in ethics. In this paper, I offer a two-part reply to Greco. First, I argue that his argument in favor of the openness of epistemology is not persuasive. Second, I offer a case against the openness of epistemology. Unlike claims linking natural and moral properties, claims linking natural and epistemological properties do give rise to closed questions. An epistemological OQA is therefore not as promising as its moral cousin. (shrink)

Un calcul logique, au sens large, est une méthode de résolution appliquée au traitement d'une structure propositionnelle. Les propositions constituant cette structure peuvent aussi bien être des expressions d'une langue naturelle (comme le français) que des expressions d'un langage formalisé (comme l'arithmétique), liées entre elles par une dépendance de nature fonctionnelle. Cet ouvrage constitue une introduction à deux outils de calcul en logique du premier ordre, soit le calcul en arbres de consistance et le calcul en déduction naturelle. La première (...) partie, centrée sur la notion de structure propositionnelle, expose les concepts, les objets et les méthodes propres à la logique propositionnelle. Dans la deuxième partie, la logique propositionnelle est étendue à la logique prédicative au moyen de la quantification et de concepts caractéristiques d'un langage du premier ordre. Les deux outils de calcul sont ensuite enrichis de manière à pouvoir traiter des fonctions propositionnelles, soit des prédicats du premier ordre.De nombreux exemples et exercices, accompagnés de leurs solutions, aideront l'étudiant à progresser vers des calculs toujours plus complexes et à raffiner ses méthodes de calcul logique.
