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.

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)

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)

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.

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)

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.

El artículo enfoca la crítica de la imagen dogmática en Deleuze desde un análisis retrospectivo del papel que desempeña la noción de «imagen del pensamiento» en su obra. Tras desgranar brevemente los distintos sentidos e interpretaciones con que el autor la utiliza y cerrar la introducción con la exposición del uso plenamente positivo que ese sintagma acabará adquiriendo en él, nos remontamos hasta el uso crítico y cronológicamente anterior –que no primero– de la expresión, donde la palabra «Imagen» señala esa (...) preconcepción tradicional, común a la filosofía y al buen sentido, de un pensamiento pretendidamente «natural», con el fin de arrojar una luz nueva sobre los principales ejes en torno a los cuales semejante Imagen se estructura.

In this paper, we develop a fresh understanding of the sense in which emotions are evaluations. We argue that we should not follow mainstream accounts in locating the emotion–value connection at the level of content and that we should instead locate it at the level of attitudes or modes. We begin by explaining the contrast between content and attitude, a contrast in the light of which we review the leading contemporary accounts of the emotions. We next offer reasons to think (...) that these accounts face substantial problems since they locate the link emotions bear to values at the level of content. This provides the incentive to pursue an alternative approach according to which emotions qualify as evaluations because they are specific types of attitudes, an approach we substantiate by appealing to felt bodily stances. We conclude by considering two reasons why this approach may be resisted; they respectively pertain to the alleged impossibility of drawing the attitude–content contrast in the case of the emotions and to the suspicion that so doing raises qualia-related worries.

How does shame differ from guilt? Empirical psychology has recently offered distinct and seemingly incompatible answers to this question. This article brings together four prominent answers into a cohesive whole. These are that (a) shame differs from guilt in being a social emotion; (b) shame, in contrast to guilt, affects the whole self; (c) shame is linked with ideals, whereas guilt concerns prohibitions and (d) shame is oriented towards the self, guilt towards others. After presenting the relevant empirical evidence, we (...) defend specific interpretations of each of these answers and argue that they are related to four different dimensions of the emotions. This not only allows us to overcome the conclusion that the above criteria are either unrelated or conflicting with one another, it also allows us to tell apart what is constitutive from what is typical of them. -/- .

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.

Since Saul Kripke’s influential work in the 1970s, the revisionary approach to semantic paradox—the idea that semantic paradoxes must be solved by weakening classical logic—has been increasingly popular. In this paper, we present a new revenge argument to the effect that the main revisionary approaches breed new paradoxes that they are unable to block.

La série d’articles écrits par Michel Foucault sur le soulèvement iranien de 1978 a été l’objet de vives polémiques. L’analyse sérieuse et attentive d’un tel corpus montre pourtant l’intérêt qui est le sien tant sur le plan historique que conceptuel. C’est sur la notion de « spiritualité politique », certainement la plus importante des articles, que nous nous arrêterons tout particulièrement ici. Nous tenterons d’abord de comprendre pourquoi, comment et contre quoi une telle notion a émergé dans l’entreprise de description (...) de l’événement. Nous verrons ensuite les pistes et hypothèses qu’elle ouvre aujourd’hui, tant pour la recherche proprement foucaldienne que pour les recherches d’ordre théologico-politique. (shrink)

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.

Les jeunes « radicalisés » sont confrontés à des mouvements de questionnements internes et externes, comme grand nombre d’adolescents, sur leur filiation, leur identité. Leur engagement dans cet horizon guerrier s’inscrit autour de menaces psychiques inexorables face à des impensés dans leur histoire individuelle et collective. Appuyé par une méthodologie complémentariste, l’article analyse la situation de deux jeunes hommes confrontés à des reviviscences traumatiques de non-dits familiaux et la réactivation de mouvements internes et externes non maîtrisables. Malgré la tentative de (...) maîtriser ces menaces, la radicalité semble renvoyer à une violence sociale et politique menaçante. (shrink)

Simone Weil (1909-1943), philosophe reconnue, engagée, mystique, ne laisse personne indifférent. Son année d'enseignement à Bourges (octobre 1935-juin 1936) est une année charnière, un moment de répit dans une courte vie mouvementée. Elle y réfléchit et y médite. Professeur de philosophie, elle a laissé une forte impression sur ses jeunes élèves du lycée de jeunes filles de Bourges. Ce sont ses cours, retrouvés grâce à deux anciennes élèves, que vous lirez dans cet ouvrage.

Huemer defends phenomenal conservatism (PC) and also the further claim that belief in any rival theory is self-defeating (SD). Here I construct a dilemma for his position: either PC and SD are incompatible, or belief in PC is itself self-defeating. I take these considerations to suggest a better self-defeat argument for (belief in) PC and a strong form of internalism.

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)

Is shame social? Is it superficial? Is it a morally problematic emotion? Researchers in disciplines as different as psychology, philosophy, and anthropology have thought so. But what is the nature of shame and why are claims regarding its social nature and moral standing interesting and important? Do they tell us anything worthwhile about the value of shame and its potential legal and political applications? -/- In this book, Julien Deonna, Raffaele Rodogno, and Fabrice Teroni propose an original philosophical account (...) of shame aimed at answering these questions. The book begins with a detailed examination of the evidence and arguments that are taken to support what they call the two dogmas about shame: its alleged social nature and its morally dubious character. Their analysis is conducted against the backdrop of a novel account of shame and ultimately leads to the rejection of these two dogmas. On this account, shame involves a specific form of negative evaluation that the subject takes towards herself: a verdict of incapacity with regard to values to which she is attached. One central virtue of the account resides in the subtle manner it clarifies the ways in which the subject's identity is at stake in shame, thus shedding light on many aspects of this complex emotion and allowing for a sophisticated understanding of its moral significance. -/- This philosophical account of shame engages with all the current debates on shame as they are conducted within disciplines as varied as ethics, moral, experimental, developmental and evolutionary psychology, anthropology, legal studies, feminist studies, politics and public polic.

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)

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)

Taking our lead from Solomon’s emphasis on the importance of the intentional object of emotion, we review the history of repeated attempts to make this object disappear. We adduce evidence suggesting that in the case of James and Schachter, the intentional object got lost unintentionally. By contrast, modern constructivists seem quite determined to deny the centrality of the intentional object in accounting for the occurrence of emotions. Griffiths, however, downplays the role objects have in emotion noting that these do not (...) qualify as intentional. We argue that these disappearing acts, deliberate or not, generate fruitless debate and add little to the advancement of our understanding of emotion as an adaptive mechanism to cope with events that are relevant to an organism’s life.

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)

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.

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)

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.

For the past two decades, philosophers of religion have paid close attention to the debates on public reason taking place within the context of political philosophy. Some thinkers claim that religious arguments should play a very limited role in political discourse, as this would amount to a politically sanctioned imposition of religious beliefs on people with different religious or non-religious worldviews. Others claim that excluding religious reasons would lead to an unfair exclusion of religious citizens from democratic processes. Underlying these (...) positions is a highly problematic idea of what it means to be a religious citizen. On the one hand, religious citizens are conceptualized as highly self-reflective theologians. Others instead imagine religious citizens to be wholly incapable of such self-reflection and of distinguishing between public and non-public spheres. In my article I attempt to criticize these underlying assumptions and point towards a more nuanced conception of the religious citizen. (shrink)

Abstract The content of an emotion, unlike the content of a perception, is directly dependent on the motivational set of the subject experiencing the emotion. Given the instability of this motivational set, it might be thought that there is no sense in which emotions can be said to pick up information about the environment in the same way that perception does. Whereas it is admitted that perception tracks for us what is the case in the environment, no such tracking relation, (...) it is argued, holds between one's emotions and what they are about. It is to this worry – that the construal of the emotions as perceptions inevitably raises – that this paper tries to respond. In this paper, I suggest that when it is realized that one dimension of perception itself is directly dependent on the perceiver's perspective on her environment, then emotion, which is also essentially perspectival in this sense, bears the comparison with perception very well. After having clarified the nature and the role that perspective plays in perception, I argue that, in the case of emotions, the same perspectival role can be played by agents’ long-standing evaluative tendencies and character traits. The resulting conception of emotion as perception is then tested against possible objections. (shrink)

C'est sur la nécessité de l'absence d'une telle définition que Julien Busse invite à se pencher pour en analyser aussi bien les causes que les effets.

On a widespread naturalist view, the meanings of mathematical terms are determined, and can only be determined, by the way we use mathematical language—in particular, by the basic mathematical principles we’re disposed to accept. But it’s mysterious how this can be so, since, as is well known, minimally strong first-order theories are non-categorical and so are compatible with countless non-isomorphic interpretations. As for second-order theories: though they typically enjoy categoricity results—for instance, Dedekind’s categoricity theorem for second-order PA and Zermelo’s quasi-categoricity (...) theorem for second-order ZFC—these results require full second-order logic. So appealing to these results seems only to push the problem back, since the principles of second-order logic are themselves non-categorical: those principles are compatible with restricted interpretations of the second-order quantifiers on which Dedekind’s and Zermelo’s results are no longer available. In this paper, we provide a naturalist-friendly, non-revisionary solution to an analogous but seemingly more basic problem—Carnap’s Categoricity Problem for propositional and first-order logic—and show that our solution generalizes, giving us full second-order logic and thereby securing the categoricity or quasi-categoricity of second-order mathematical theories. Briefly, the first-order quantifiers have their intended interpretation, we claim, because we’re disposed to follow the quantifier rules in an open-ended way. As we show, given this open-endedness, the interpretation of the quantifiers must be permutation-invariant and so, by a theorem recently proved by Bonnay and Westerståhl, must be the standard interpretation. Analogously for the second-order case: we prove, by generalizing Bonnay and Westerståhl’s theorem, that the permutation invariance of the interpretation of the second-order quantifiers, guaranteed once again by the open-endedness of our inferential dispositions, suffices to yield full second-order logic.

In this paper, we contrast the different ways in which the representationalist and the attitudinalist in the theory of emotions account for the fact that emotions have evaluative correctness conditions. We argue that the attitudinalist has the resources to defend her view against recent attacks from the representationalist. To this end, we elaborate on the idea that emotional attitudes have a rich profile and explain how it supports the claim that these attitudes generate the wished-for evaluative correctness conditions. Our argument (...) rests on the idea that emotional attitudes manifest a sensitivity to evaluative evidence and that this sensitivity secures the kind of normativity we expect of the emotions. We bring our discussion to a close by assessing whether the psychological underpinnings of this sensitivity to evaluative evidence are such as to threaten the foundation of attitudinalism: the idea that emotions do not represent values. Given the available models of how we might access values prior to emotional experience, we conclude that the attitudinalist is still in the game. (shrink)

Objective Our study sought to (1) describe the practices and preferences of Colombian adolescents in accessing sexual and reproductive health services: accompanied versus alone; (2) compare actual practices with stated preferences; and (3) determine age and gender differences regarding the practice and these stated preferences. -/- Methods 812 participants aged 11–24 years old answered a survey in two Profamilia clinics in the cities of Medellin and Cali in Colombia. A cross-sectional analysis was performed to compare participants’ answers based on the (...) variables of gender and age. -/- Results A quarter of participants visited the clinic alone (25.4%). Females were more likely to go alone in comparison to males (26.3% vs 14.1%; p = 0.031), and older participants went alone more often than younger participants (p < 0.001). Most participants – 72.7% (95 %CI: 69.3–75.9) – expressed a preference in being accompanied to the clinic, and more than 90% had their preferences met. The preferences of older participants were, however, less likely to be met than those of younger participants (p < 0.001), notably, because they predominantly wanted to be accompanied. -/- Conclusion Contemporary public health and bioethics literature advocates in favor of developing health services that better meet the preferences of adolescents. The present research highlights an apparent blind spot related to the role that others (e.g., parents, friends, partners) can or should play in accompanying adolescent patients when they access sexual and reproductive health services. Respecting adolescents’ preferences, and hence their autonomy, is not simply a matter of ensuring freedom from constraints (e.g., their right and ability to go alone). Rather, it should also consider the liberty to choose whether to be accompanied when accessing SHRS and by whom. (shrink)
