A substantial body of experimental evidence has demonstrated that labels have an impact on infant categorization processes. Yet little is known regarding the nature of the mechanisms by which this effect is achieved. We distinguish between two competing accounts: supervised name‐based categorization and unsupervised feature‐based categorization. We describe a neurocomputational model of infant visual categorization, based on self‐organizing maps, that implements the unsupervised feature‐based approach. The model successfully reproduces experiments demonstrating the impact of labeling on infant visual categorization reported in (...) Plunkett, Hu, and Cohen (2008). It mimics infant behavior in both the familiarization and testing phases of the procedure, using a training regime that involves only single presentations of each stimulus and using just 24 participant networks per experiment. The model predicts that the observed behavior in infants is due to a transient form of learning that might lead to the emergence of hierarchically organized categorical structure and that the impact of labels on categorization is influenced by the perceived similarity and the sequence in which the objects are presented. The results suggest that early in development, say before 12 months old, labels need not act as invitations to form categories nor highlight the commonalities between objects, but they may play a more mundane but nevertheless powerful role as additional features that are processed in the same fashion as other features that characterize objects and object categories.

Yarkoni's analysis clearly articulates a number of concerns limiting the generalizability and explanatory power of psychological findings, many of which are compounded in infancy research. ManyBabies addresses these concerns via a radically collaborative, large-scale and open approach to research that is grounded in theory-building, committed to diversification, and focused on understanding sources of variation.

In this paper, my goal is to use an epistemic injustice framework to extend an existing normative analysis of over-medicalization to psychiatry and thus draw attention to overlooked injustices. Kaczmarek has developed a promising bioethical and pragmatic approach to over-medicalization, which consists of four guiding questions covering issues related to the harms and benefits of medicalization. In a nutshell, if we answer “yes” to all proposed questions, then it is a case of over-medicalization. Building on an epistemic injustice framework, I (...) will argue that Kaczmarek’s proposal lacks guidance concerning the procedures through which we are to answer the four questions, and I will import the conceptual resources of epistemic injustice to guide our thinking on these issues. This will lead me to defend more inclusive decision-making procedures regarding medicalization in the DSM. Kaczmarek’s account complemented with an epistemic injustice framework can help us achieve better forms of medicalization. I will then use a contested case of medicalization, the creation of Premenstrual Dysphoric Disorder in the DSM-5 to illustrate how the epistemic injustice framework can help to shed light on these issues and to show its relevance to distinguish good and bad forms of medicalization.

A leading critic of the disruptive force of technology in education, Bernard Stiegler saw the counter-effects of artificial intelligence in undermining human agency, autonomy and individuality, rendering the role of education ever more critical. Stiegler believes that our goal is not to abandon technology but to focus our attention on its power and direction in a hypercapitalist economy. While he did not foresee the emergence of generative artificial intelligence (GAI), its rapid acceleration raises important issues for his notion of digital (...) writing as a pharmakon. In this essay, we examine Stiegler’s view on intelligence, digital writing, technological memory, and neuropower, focusing specifically on his Shanghai lecture and Nanjing Lectures. We compare Stiegler with Catherine Malabou, who examines the nature of intelligence primarily through the lens of neuroscience. We argue that Malabou’s view of neuroplasticity in human and artificial brains, and her critique of techno-narcissism in the control over technology, add an important dimension to Stiegler’s political critique of education. Finally, we examine how best to construe AI as part of a hyper-materialist epistemology that Stiegler espouses in the conclusion of his Nanjing Lectures, to bring about neganthropic knowledge through a therapeutics of care.

According to the fitting attitude (FA) analysis of value concepts, to conceive of an object as having a given value is to conceive of it as being such that a certain evaluative attitude taken towards it would be fitting. Among the challenges that this analysis has to face, two are especially pressing. The first is a psychological challenge: the FA analysis must call upon attitudes that shed light on our value concepts while not presupposing the mastery of these concepts. The (...) second challenge is normative: the FA analysis must account for the fittingness of the relevant attitudes in terms of a kind of normativity intimately related to these attitudes, but again without presupposing the mastery of the relevant value concepts. In this paper, we show that real progress is possible if we pay close attention to the nature of the attitudes recruited by the analysis. More specifically, we claim that an FA analysis that appeals to emotions conceived as evaluative attitudes — as opposed to, for instance, evaluative judgements or evaluative perceptions — has the best prospects of meeting the two challenges and of putting the FA analysis on a strong footing.

In this article, I side with those who argue that the debate about the definition of “disease” should be reoriented from the question “what is disease” to the question of what it should be. However, I ground my argument on the rejection of the naturalist approach to define disease and the adoption of a normativist approach, according to which the concept of disease is normative and value-laden. Based on this normativist approach, I defend two main theses: (1) that conceptual analysis (...) is not the right method to define disease and that conceptual engineering should be the preferred method and (2) that the method of conceptual engineering should be implemented following the principles of Alexandrova’s account of social objectivity in the context of the definition of disease.

Cet ouvrage interroge les articulations problématiques entre art, flux et contemporain, à partir de pratiques artistiques actuelles où interviennent le quotidien, le sociologique et le collectif. Traversé par des flux de toute sorte, le monde contemporain soulève la question de sa représentabilité, alors que les artistes ont, depuis toujours, éprouvé le besoin de se mettre en adéquation avec lui. Comment en effet montrer ce qui sans cesse se meut? Pourquoi suivre les mouvances du monde? Et finalement, que peut l'art d'aujourd'hui? (...) Il s'agit pour les artistes d'adopter une position de contemporanéité car toute observation du monde, fût-elle opérée sur un mode contemplatif, ne peut être l'objet de l'inactif et de l'inopérant. C'est pourquoi "devenir contemporain" est une nécessité, une injonction politique et éthique aussi bien qu'esthétique. Il nous faut dès lors entreprendre une "esthétique du contemporain", elle qui nous portera vers un "contemporain de l'esthétique" guidé par les flux et les devenirs. (shrink)

One puzzle concerning highly idealized models is whether they explain. Some suggest they provide so-called ‘how-possibly explanations’. However, this raises an important question about the nature of how-possibly explanations, namely what distinguishes them from ‘normal’, or how-actually, explanations? I provide an account of how-possibly explanations that clarifies their nature in the context of solving the puzzle of model-based explanation. I argue that the modal notions of actuality and possibility provide the relevant dividing lines between how-possibly and how-actually explanations. Whereas how-possibly (...) explanations establish claims of possible explanations, how-actually explanations establish claims of actual ones. Models, in turn, simply provide evidence for these claims. (shrink)

There is a traditional conception of knowledge but it is not the Justified True Belief analysis Gettier attacked. On the traditional view, knowledge consists in having a belief that bears a discernible mark of truth. A mark of truth is a truth-entailing property: a property that only true beliefs can have. It is discernible if one can always tell that a belief has it, that is, a sufficiently attentive subject believes that a belief has it if and only if it (...) has it. Requiring a mark of truth makes the view infallibilist. Requiring it to be discernible makes the view internalist. I call the view Classical Infallibilism. (shrink)

It is undeniable that Thomas Aquinas showed great metaphysical originality among his contemporaries. However, his advances concerning the meaning of the uniqueness of the substantial form cannot be adequately grasped independently of an equally original understanding of matter, conceived in particular as pure power. This study attempts to grasp the implications of the Thomasian conception of matter in the various fields of his thought, from physics to metaphysics, passing through the foundations, in the very constitution of substance, theories of knowledge, (...) of moral action and apprehension of the beautiful. We discover a conception of the substance-subject in the strong sense which nevertheless shows itself, at the very heart of its constitutive principles, radically open to the originality of Otherness in its various forms.

When spelled out properly infallibilism is a viable and even attractive view. Because it has long been summary dismissed, however, we need a guide on how to properly spell it out. The guide has to fulfil four tasks. The first two concern the nature of knowledge: to argue that infallible belief is necessary, and that it is sufficient, for knowledge. The other two concern the norm of belief: to argue that knowledge is necessary, and that it is sufficient, for justified (...) certainty. With such a guide in hand infallibilism can be evaluated on its own merits. The most controversial parts are the first and fourth. The idea that knowledge requires infallible belief is thought to be excessively sceptical. The idea that knowledge warrants certainty is thought to be excessively dogmatic. The present paper addresses the first. It argues that knowledge requires infallible belief. (shrink)

The emotions are at the centre of our lives and, for better or worse, imbue them with much of their significance. The philosophical problems stirred up by the existence of the emotions, over which many great philosophers of the past have laboured, revolve around attempts to understand what this significance amounts to. Are emotions feelings, thoughts, or experiences? If they are experiences, what are they experiences of? Are emotions rational? In what sense do emotions give meaning to what surrounds us? (...) -/- The Emotions: A Philosophical Introduction introduces and explores these questions in a clear and accessible way. The authors discuss the following key topics: -/- the diversity and unity of the emotions the relations between emotion, belief and desire the nature of values the relations between emotions and perceptions emotions viewed as evaluative attitudes the link between emotions and evaluative knowledge the nature of moods, sentiments, and character traits. -/- Including chapter summaries and guides to further reading, The Emotions: A Philosophical Introduction is an ideal starting point for any philosopher or student studying the emotions. It will also be of interest to those in related disciplines such as psychology and the social sciences. (shrink)

The revisionary approach to semantic paradox is commonly thought to have a somewhat uncomfortable corollary, viz. that, on pain of triviality, we cannot affirm that all valid arguments preserve truth (Beall2007, Beall2009, Field2008, Field2009). We show that the standard arguments for this conclusion all break down once (i) the structural rule of contraction is restricted and (ii) how the premises can be aggregated---so that they can be said to jointly entail a given conclusion---is appropriately understood. In addition, we briefly rehearse (...) some reasons for restricting structural contraction. (shrink)

For Hannah Arendt, authority is the shape educational responsibility assumes. In our time, authority in Arendt’s sense is under pressure. The figure of Greta Thunberg shows the failure of adult generations, taken collectively, to take responsibility for the world and present and future generations of newcomers. However, in reflecting on Arendt’s use of authority, we argue that her account of authority also requires amendments. Arendt’s situating of educational authority in-between past and future adequately captures its temporal dimension. We make explicit (...) another, spatial, dimension: authority in-between world and earth. Arendt’s neglect of the material earth also has implications for the relational dimension of authority. Arendt’s authority depends on a dichotomy between the private and the public sphere. This is problematic. First, we agree with Arendt’s feminist critics that the personal can be made into the site of the political. Second, we point once more to Thunberg, the child, taking the public stage, thereby contesting the division between public and private. In response, we situate the relational dimension of authority in-between private and public. The three dimensions of educational authority taken together imply that it is situated in-between domains that cannot be reduced to each other or taken as absolutes: past and future, world and earth, and the private and public sphere. This brings us to our concept of ambiguous authority, which expresses the Arendtian nature of our reflections and the ways in which we seek to renew her original insights on educational authority.

The phenomenon of species extinction raises more and more concern among ecologists facing the actual crisis of biodiversity. Scientific investigations of the causes and effects of extinction must be completed by a philosophical analysis of the concept of extinction that aims to clarify the meanings of the term ‘extinction’ and to analyse modalities, criteria and degrees of extinction. We will focus our attention on the apparent paradox of the possible ‘resurrection’ of species in the near future with the help of (...) genetic biotechnology and cloning techniques. The ontological background of the extinction concept is analysed in relation to the idea of species as classes. We will also show that there is no simple analogy between death and species extinction, and develop a conceptualist and dualistic system of supra-individual entities , supported by an instrumentalist approach to genetic manipulations which transform species into interactive kinds, which can go extinct and be recreated.

Widespread preservation of fossilized biomolecules in many fossil animals has recently been reported in six studies, based on Raman microspectroscopy. Here, we show that the putative Raman signatures of organic compounds in these fossils are actually instrumental artefacts resulting from intense background luminescence. Raman spectroscopy is based on the detection of photons scattered inelastically by matter upon its interaction with a laser beam. For many natural materials, this interaction also generates a luminescence signal that is often orders of magnitude more (...) intense than the light produced by Raman scattering. Such luminescence, coupled with the transmission properties of the spectrometer, induced quasi‐periodic ripples in the measured spectra that have been incorrectly interpreted as Raman signatures of organic molecules. Although several analytical strategies have been developed to overcome this common issue, Raman microspectroscopy as used in the studies questioned here cannot be used to identify fossil biomolecules.

How can we use models to understand real phenomena if models misrepresent the very phenomena we seek to understand? Some accounts suggest that models may afford understanding by providing causal knowledge about phenomena via how-possibly explanations. However, general equilibrium models, for example, pose a challenge to this solution since their contribution appears to be purely mathematical results. Despite this, practitioners widely acknowledge that it improves our understanding of the world. I argue that the Arrow–Debreu model provides a mathematical how-possibly explanation (...) which establishes claims of mathematical dependence. The account developed reveals how mathematical knowledge can inform claims about the world, allow ‘what-if-things-had-been-different’ inferences, and thus improve our understanding. (shrink)

While it is generally believed that justification is a fallible guide to the truth, there might be interesting exceptions to this general rule. In recent work on bridge-principles, an increasing number of authors have argued that truths about what a subject ought to do are truths we stand in some privileged epistemic relation to and that our justified normative beliefs are beliefs that will not lead us astray. If these bridge-principles hold, it suggests that justification might play an interesting role (...) in our normative theories. In turn, this might help us understand the value of justification, a value that's notoriously difficult to understand if we think of justification as but a fallible means to a desired end. We will argue that these bridge-principles will be incredibly difficult to defend. While we do not think that normative facts necessarily stand in any interesting relationship to our justified beliefs about them, there might well be a way of defending the idea that our justified beliefs about what to do won't lead us astray. In turn, this might help us understand the value of justification, but this way of thinking about justification and its value comes with costs few would be willing to pay. (shrink)

Sven Rosenkranz’s Justification as Ignorance shows how a strongly internalist conception of justification can be derived from a strongly externalist conception of knowledge, given an identification of justification with second-order ignorance and a set of structural principles concerning knowing and being in a position to know. Among these principles is an epistemic analogue of the Geach modal schema which states that one is always in a position to know that one doesn’t know p or in a position to know that (...) one doesn’t know not-p. Even suitably refined, the principle faces a range of counterexamples in which it misleadingly and persistently seems to one that one knows whether p without it seeming to one that one knows p nor that one knows not-p. These cases also threaten the book’s case for the luminosity of second-order ignorance, which is in turn central to its derivation of strongly internalist principles of justification. (shrink)

Argumentation has been an important topic in knowledge representation, reasoning and multi-agent systems during the last twenty years. In this paper, we propose a new abstract framework where arguments are associated with a strength, namely a quantitative information which is used to determine whether an attack between arguments succeeds or not. Our Strength-based Argumentation Framework combines ideas of Preference-based and Weighted Argumentation Frameworks in an original way, which permits to define acceptability semantics sensitive to the existence of accruals between arguments. (...) The question of accruals arises in situations where several arguments defending the same position against another argument are unable to individually defeat this argument, but could do it collectively if they combine their strengths. We investigate some of the theoretical and computational properties of our new framework and semantics, and present a reasoning algorithm that is based on a translation of the problem into pseudo-boolean constraint satisfaction. This paper proposes an intuitive framework which allows strength compensations in an argumentation context where attacks may not succeed, completed by an approach which detects accruals throughout the reasoning process without requiring the elicitation of all compensatory combinations of arguments as an input.

Vers une stylistique des imaginaires langagiers Si la description du matériau langagier mis en jeu dans tel ou tel corpus se situe à la base de toute analyse stylistique, la visée ultime de l’opération est d’approcher un style, catégorie littéraire éminemment polysémique. L’analyse stylistique, en effet, peut avoir pour finalité de dégager les habitudes langagières de tel auteur ; elle peut aussi vouloir évaluer cette pratique en l’historicisant – ne serait-ce que parce que depuis le milieu du xixe siècle, la (...) langue littéraire présente des formes particulières, et que la conception du style, dès lors, s’en trouve modifiée. C’est là le postulat méthodologique dont on partira. Le corollaire d’une telle perspective est qu’une œuvre, quelle qu’elle soit, reflète un imaginaire langagier inscrit dans tel ou tel « moment » de l’histoire littéraire. La démarche ne peut être que comparative ; elle suppose donc la constitution d’un corpus pluriel dont la pertinence est définie par une proximité d’effets, qui reposent eux-mêmes sur la récurrence de « patrons » stylistiques. Mais afin de ne pas fausser le jeu, il faut nécessairement solliciter des corpus périphériques (et on se demandera comment les définir), permettant de mettre en évidence des ressemblances et des filiations aussi bien que des divergences : ce n’est qu’ainsi que l’on rendra compte de la complexité mais aussi de l’organisation du champ littéraire à un moment donné. C’est cette méthode d’analyse stylistique que l’on essaie de mettre en œuvre à partir des romans de Samuel Beckett, Robert Pinget et Claude Simon parus dans les années 1950. (shrink)

Knowledge-first evidentialism combines the view that it is rational to believe what is supported by one's evidence with the view that one's evidence is what one knows. While there is much to be said for the view, it is widely perceived to fail in the face of cases of reasonable error—particularly extreme ones like new Evil Demon scenarios (Wedgwood, 2002). One reply has been to say that even in such cases what one knows supports the target rational belief (Lord, 201x, (...) this volume). I spell out two versions of the strategy. The direct one uses what one knows as the input to principles of rationality such as conditionalization, dominance avoidance, etc. I argue that it fails in hybrid cases that are Good with respect to one belief and Bad with respect to another. The indirect strategy uses what one knows to determine a body of supported propositions that is in turn the input to principles of rationality. I sketch a simple formal implementation of the indirect strategy and show that it avoids the difficulty. I conclude that the indirect strategy offers the most promising way for knowledge-first evidentialists to deal with the New Evil Demon problem. (shrink)

Models typically have actual, existing targets. However, some models are viewed as having non-actual targets. I argue that this interpretation comes at various costs and propose an alternative that fares better along two dimensions: (1) agreement with practice and (2) ontological and epistemological parsimony. My proposal is that many of these models actually have actual targets.

The ethics of safe sex in the gay community has, for many years, been focused on debates surrounding the responsibility regarding the use of condoms to prevent HIV transmission, once the only tool available. With the development of Truvada as a pre-exposure prophylaxis for HIV, for the first time in the history of the HIV/AIDS epidemic there is the potential to significantly reduce the risk of HIV transmission during sex without the use of condoms. The introduction of PrEP necessitates a (...) renewed discussion about the politics and ethics of safe sex for men who have sex with men. We present the arguments of authors who hold radically opposite positions with regard to the ethics of condom use by gay men, but who currently both criticize the use of PrEP. We offer a critique of their arguments and advance the position that the use of PrEP, even without condoms, can be acceptable and part of a safe sex ethics framework for MSM. (shrink)

In this article, we present, assess and give reasons to reject the popular claim that shame is essentially social. We start by presenting several theses which the social claim has motivated in the philosophical literature. All of them, in their own way, regard shame as displaying a structure in which "others" play an essential role. We argue that while all these theses are true of some important families of shame episodes, none of them generalize so as to motivate the conclusion (...) that shame is an essentially social emotion. We consider each thesis in turn, explaining in the process their connections with one another as well as the constraints on a theory of shame they help uncover. Finally, we show how a non-social picture of shame is not only capable of meeting these constraints, but has the further virtue of shedding light on those situations in which others seem to play no role in why we feel shame.

RNA polymerase II (RNAP II) non‐coding transcription is now known to cover almost the entire eukaryotic genome, a phenomenon referred to as pervasive transcription. As a consequence, regions previously thought to be non‐transcribed are subject to the passage of RNAP II and its associated proteins for histone modification. This is the case for the nucleosome‐depleted regions (NDRs), which provide key sites of entry into the chromatin for proteins required for the initiation of coding gene transcription and DNA replication. In this (...) review, recent data on the effects of pervasive transcription through NDRs are summarized and a model is proposed to explain how RNAP II‐driven transcription is able to modify the nucleosomes flanking the NDRs, leading to nucleosome repositioning and NDR closure. Even though much of the mechanistic detail underlying these events remains to be elucidated, such a model provides a basis to explain how non‐coding transcription through NDRs can regulate the initiation of coding gene expression and DNA replication.
