Social learning is likely to include affective processes: it is necessary for newcomers to discover what value to attach to objects, persons, and events in a given social environment. This learning relies largely on the evaluation of others’ emotional expressions. This study has two objectives. Firstly, we compare two closely related concepts that are employed to describe the use of another person’s appraisal to make sense of a given situation: social appraisal and social referencing. We contend that social referencing constitutes (...) a type of social appraisal. Secondly, we introduce the concept of affective social learning with the hope that it may help to discriminate the different ways in which emotions play a critical role in the processes of socialization.

Recent metaphysics has turned its focus to two notions that are—as well as having a common Aristotelian pedigree—widely thought to be intimately related: grounding and essence. Yet how, exactly, the two are related remains opaque. We develop a unified and uniform account of grounding and essence, one which understands them both in terms of a generalized notion of identity examined in recent work by Fabrice Correia, Cian Dorr, Agustín Rayo, and others. We argue that the account comports with antecedently (...) plausible principles governing grounding, essence, and identity taken individually, and illuminates how the three interact. We also argue that the account compares favorably to an alternative unification of grounding and essence recently proposed by Kit Fine. (shrink)

The connection between shame, guilt and morality is the topic of many recent debates. A broad tendency consists in attributing a higher moral status and a greater moral relevance to guilt, a claim motivated by arguments that tap into various areas of morality and moral psychology. The Pro-social Argument has it that guilt is, contrary to shame, morally good since it promotes pro-social behaviour. Three other arguments claim that only guilt has the requisite connection to central moral concepts: the Responsibility (...) Argument appeals to the ties between guilt and responsibility, the Autonomy Argument to the heteronomy of shame and the Social Argument to shame's link with reputation. In this paper, we scrutinize these arguments and argue that they cannot support the conclusion that they try to establish. We conclude that a narrow focus on particular criteria and a misconception of shame and guilt have obscured the important roles shame plays in our moral lives. (shrink)

This monograph is a detailed study, and systematic defence, of the Growing Block Theory of time (GBT), first conceived by C.D. Broad. The book offers a coherent, logically perspicuous and ideologically lean formulation of GBT, defends it against the most notorious objections to be found in the extant philosophical literature, and shows how it can be derived from a more general theory, consistent with relativistic spacetime, on the pre-relativistic assumption of an absolute and total temporal order. -/- The authors devise (...) axiomatizations of GBT and its competitors which, against the backdrop of a shared quantified tense logic, significantly improves the prospects of their comparative assessment. Importantly, neither of these axiomatizations involves commitment to properties of presentness, pastness or futurity. The authors proceed to address, and defuse, a number of objections that have been marshaled against GBT, including the so-called epistemic objection according to which the theory invites skepticism about our temporal location. The challenge posed by relativistic physics is met head-on, by replacing claims about temporal variation by claims about variation across spacetime. -/- The book aims to achieve the greatest possible rigor. The background logic is set out in detail, as are the principles governing the notions of precedence and temporal location. The authors likewise devise a novel spacetime logic suited for the articulation, and comparative assessment, of relativistic theories of time. The book comes with three technical appendices which include soundness and completeness proofs for the systems corresponding to GBT and its competitors, in both their pre-relativistic and relativistic forms. -/- The book is primarily directed at researchers and graduate students working on the philosophy of time or temporal logic, but is of interest to metaphysicians and philosophical logicians more generally.

How does metaphysical grounding interact with the truth-functions? I argue that the answer varies according to whether one has a worldly conception or a conceptual conception of grounding. I then put forward a logic of worldly grounding and give it an adequate semantic characterisation.

This paper suggests that the enactive approach to ethics could benefit from engaging a dialogue with the phenomenology of Emmanuel Levinas, a philosopher who has given ethics a decisive role in the understanding of our social life. Taking the enactive approach of Colombetti and Torrance as a starting point, we show how Levinas’ philosophy, with the key notions of face, otherness, and responsibility among others can complement and enrich the enactive view of ethics. Specifically, we argue that Levinas can provide, (...) on the one hand, a phenomenological characterisation of ethics itself, of its nature and fundamental meaning, and on the other, an account of how sociality, affectivity and embodiment, as presented in Colombetti and Torrance’s work, combine to bring about the ethical experience. However, we also point out that introducing Levinas to the enactive approach could be challenging. It is not obvious how sense-making and value-making, as centred on the precariousness and potential death of the subject, would account for the ethical experience as grounded on the precariousness and potential death of the other.

Some of the most eminent and enduring philosophical questions concern matters of priority: what is prior to what? What 'grounds' what? Is, for instance, matter prior to mind? Recently, a vivid debate has arisen about how such questions have to be understood. Can the relevant notion or notions of priority be spelled out? And how do they relate to other metaphysical notions, such as modality, truth-making or essence? This volume of new essays, by leading figures in contemporary metaphysics, is the (...) first to address and investigate the metaphysical idea that certain facts are grounded in other facts. An introduction introduces and surveys the debate, examining its history as well as its central systematic aspects. The volume will be of wide interest to students and scholars of metaphysics.

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.

The evaluations involved in shame are, intuitively at least, of many different sorts. One feels ashamed when seen by others doing something one would prefer doing alone (social shame). One is ashamed because of one’s ugly nose (shame about permanent traits). One feels ashamed of one’s dishonest behavior (moral shame), etc. The variety of evaluations in shame is striking; and it is even more so if one takes a cross-cultural perspective on this emotion. So the difficulty – the “unity problem” (...) of shame- turns out to be the following: is there a common trait shared by all shame evaluations that will allow us to differentiate these evaluations from those that feature in other negative self-reflexive emotions like anger at oneself or self disappointment? Some progress is perhaps accomplished if we say that, in shame, a given trait or behavior is evaluated as degrading or as revealing one’s lack of worth. Still, even if we agree with this last claim, truth is that these answers are less illuminating than we might wish. A theory of shame should surely further elucidate the aspect of one’s identity relevant for shame, namely, the self of shame. In this connexion, philosophers have referred to “self-esteem,” “self-respect” or the “social self,” significantly disagreeing thus on which aspect of one’s identity is at stake in shame. After critically discussing the different solutions to the problem, we offer our own. Shame, we claim, consists in an awareness of a distinctive inability to discharge a commitment that goes with holding self-relevant values. This conception solves the unity problem while illuminating other aspects of this emotion. (shrink)

Psychologists have emphasized children's acquisition of information through firsthand observation. However, many beliefs are acquired from others' testimony. In two experiments, most 4yearolds displayed sceptical trust in testimony. Having heard informants' accurate or inaccurate testimony, they anticipated that informants would continue to display such differential accuracy and they trusted the hitherto reliable informant. Yet they ignored the testimony of the reliable informant if it conflicted with what they themselves had seen. By contrast, threeyearolds were less selective in trusting a reliable (...) informant. Thus, young children check testimony against their own experience and increasingly recognise that some informants are more trustworthy than others. (shrink)

I offer and defend an account of real definitions. I put forward two versions of the account, one formulated in terms of the notion of generalised identity and of a suitable notion of grounding, and the other one formulated in terms of the former notion and of a suitable notion of comparative joint-carvingness. Given a plausible assumption, and turn out to be equivalent. I give a sketch of a unified account of the three notions involved in and from which the (...) assumption can be derived. (shrink)

In recent publications, Kit Fine devises a classification of A-theories of time and defends a non-standard A-theory he calls fragmentalism, according to which reality as a whole is incoherent but fragments into classes of mutually coherent tensed facts. We argue that Fine's classification in not exhaustive, as it ignores another non-standard A-theory we dub dynamic absolutism, according to which there are tensed facts that stay numerically the same and yet undergo qualitative changes as time goes by. We expound this theory (...) in some detail and argue that it is a serious alternative to the positions identified by Fine. (shrink)

I assume that truth-making is to be understood in terms of grounding, and I show how, on that assumption, various general properties of truth-making follow from certain features of grounding.

A long-standing debate surrounds the question as to what justifies memory judgements. According to the Past Reason Theory, these judgements are justified by the reasons we had to make identical judgements in the past, whereas the Present Reason Theory claims that these justifying reasons are to be found at the time we pass the memory judgements. In this paper, I defend the original claim that, far from being exclusive, these two theories should be applied to different kinds of memory judgements. (...) The Past Reason Theory offers the most appealing account of justified propositional memory judgements, while the Present Reason Theory provides the best approach to justified episodic memory judgements. One outcome of my discussion is thus that memory is not epistemologically unified and my argument in favour of this conclusion connects with the issues of internalism, reliabilism and the basing relation.

Say that two sentences are factually equivalent when they describe the same facts or situations, understood as worldly items, i.e. as bits of reality rather than as representations of reality. The notion of factual equivalence is certainly of central interest to philosophical semantics, but it plays a role in a much wider range of philosophical areas. What is the logic of factual equivalence? This paper attempts to give a partial answer to this question, by providing an answer the following, more (...) specific question: Given a standard propositional language with negation, conjunction and disjunction as primitive operators, which sentences of the language should be taken to be factually equivalent by virtue of their logical form? The system for factual equivalence advocated in this paper is a proper fragment of the first-degree system for the logic of analytic equivalence put forward in the late seventies by R. B. Angell. I provide the system with two semantics, both formulated in terms of the notion of a situation’s being fittingly described by a linguistic item. In the final part of the paper I argue, contra a view I defended in my “Grounding and Truth-Functions”, that the logic for factual equivalence I advocate here should be preferred to Angell’s logic if one wishes to follow the general conception of the relationships between factual equivalence and the notion of grounding put forward in the 2010 paper.

This paper explores substantive accounts of emotional phenomenology so as to see whether it sheds light on key features of emotions. To this end, we focus on four features that can be introduced by way of an example. Say Sam is angry at Maria’s nasty remark. The first feature relates to the fact that anger is a negative emotion, by contrast with positive emotions such as joy and admiration (valence). The second feature is how anger differs from other emotions such (...) as sadness, fear and joy (individuation). The third concerns the objects of anger and the sense in which anger discloses the significance of Maria’s remark to Sam (intentionality). Finally, there is anger’s relation to behaviour (motivation). Does focussing on emotional phenomenology encourage specific accounts of these features? We shall see that there are reasons to think it does. Still, are these reasons of sufficient import to dispel the scepticism of those who think that nothing of consequence plays out at the personal level of emotional experience? Given the role of emotional experience in our evaluative practices, we shall conclude that they are. Our discussion is structured as follows: section 1 focuses on feeling approaches to phenomenology, section 2 on componential approaches, section 3 on perceptual approaches and section 4 on attitudinal approaches. Section 5 concludes with some observations regarding the significance of emotional phenomenology. (shrink)

In this paper, I focus on the concept of human dignity and critically assess whether such a concept, as used in the Universal Declaration on Bioethics and Human Rights, is indeed a useful tool for bioethical debates. However, I consider this concept within the context of the development of emerging technologies, that is, with a particular focus on transhumanism. The question I address is not whether attaching artificial limbs or enhancing particular traits or capacities would dehumanize or undignify persons but (...) whether nonbiological entities introduced into or attached to the human body contribute to the “augmentation” of human dignity. First, I outline briefly how the Universal Declaration on Bioethics and Human Rights uses the concept of dignity. Second, I look at the possibility of a universal bioethics in relation to the concept of human dignity. Third, I examine the concept of posthuman dignity and whether the concept of human dignity as construed in the declaration has any relevance to posthuman dignity. (shrink)

There is a growing literature in neuroethics dealing with the problem of cognitive neuroenhancement for healthy adults. However, discussions on this topic have tended to focus on abstract theoretical positions while concrete policy proposals and detailed models are scarce. Furthermore, discussions tend to rely solely on data from the US, while international perspectives are mostly neglected. Therefore, there is a need for a volume that deals with cognitive enhancement comprehensively in three important ways: a) with conceptual implications stemming from different (...) points of view; b) with ethical, social and legal perspectives that would not be limited to one part of the world but reflect on the current situation in countries in Africa, Asia, Australia, Europe, North America and South America; and c) with discussions of concrete law and policy options. Contributors for the conceptual implications section will elaborate an important general issue (e.g. ethical acceptability of direct-to-consumer-marketing in case of cognitive enhancement drugs). Contributors for international perspectives section will provide a clear discussion on normative issues and cultural values, along with an analysis of empirical data on public attitudes on cognitive enhancement and/or prevalence (specific to the country in question). Contributors for law and policy section will offer a justification for the general policy type they argue for (1. prohibition, 2. discourage use, 3. laissez-faire, 4. encourage use, and 5. mandatory use) in the case of specific cognitive enhancement measure. Furthermore, they would evaluate the possible impact of a detailed regulatory model on consumption and demand, fairness in competitive settings and the social pressure to enhance. (shrink)

In Fine 1994, Kit Fine challenges the view that the notion of essence is to be understood in terms of the metaphysical modalities, and he argues that it is not essence which reduces to metaphysical modality, but rather metaphysical modality which reduces to essence. In this paper I put forward a modal account of essence and argue that it is immune from Fine’s objections. The account presupposes a non‐standard, independently motivated conception of the metaphysical modalities which I dub Priorean. Arthur (...) Prior never endorsed that very conception, but in some respects his own views on the topic are so close to it, and different from all currently accepted views, that the label ‘Priorean’ is perfectly appropriate.

In 1977, R. B. Angell presented a logic for analytic containment, a notion of relevant implication stronger than Anderson and Belnap's entailment. In this paper I provide for the first time the logic of first degree analytic containment, as presented in [2] and [3], with a semantical characterization—leaving higher degree systems for future investigations. The semantical framework I introduce for this purpose involves a special sort of truth-predicates, which apply to pairs of collections of formulas instead of individual formulas, and (...) which behave in some respects like Gentzen's sequents. This semantics captures very general properties of the truth-functional connectives, and for that reason it may be used to model a vast range of logics. I briefly illustrate the point with classical consequence and Anderson and Belnap's tautological entailments. (shrink)

Grounding is a hyperintensional notion: necessarily equivalent sentences need not be equivalent from a ground-theoretic perspective. How fine-grained, exactly, is grounding? There is a striking lack of consensus on this question. In this chapter, I try to systematize and review the main options that have been put forward in the literature. For reasons that have to do with both naturalness and convenience, I for the most part take the question to be about what is sometimes called, following Kit Fine’s (2012a) (...) terminology, strict full grounding, and I take for granted a conception of grounding as a relation that is many-to-one and non-factive. I discuss the consequences of making alternative assumptions only in the very last section. (shrink)

In this paper, we clarify what proponents of the Growing Block Theory (GBT) should and what they should not say, and what they consistently can say. Once all the central tenets of the view are on the table, we address both David Braddon-Mitchell’s and Trenton Merricks’ recent eulogies for GBT, based on what is representative of a certain type of argument meant to show that GBT is internally incoherent. We argue that this type of argument proceeds from a mistaken assumption (...) about GBT’s core, viz. that GBT works with an untensed notion of what, in the metaphysically most fundamental sense, there is. We conclude that this type of argument accordingly misfires and that for all we know, we might be living on the brink of reality. (shrink)

I provide and defend two natural accounts of fundamentality for facts that do justice to the idea that the “degree of fundamentality” enjoyed by a fact is a matter of how far, from a ground-theoretic perspective, the fact is from the ungrounded facts.

The purpose of the book is to clarify the notion of existential dependence and cognate notions, such as supervenience and the notion of an internal relation. I defend the view that such notions are best understood in terms of the concept of metaphysical grounding, i.e. the concept of one fact obtaining in virtue of other facts, where ‘in virtue of’ has a distinctively metaphysical meaning.

A possible world semantics for standard modal languages is presented, where the valuation functions are allowed to be partial, the truth–functional connectives are interpreted according to weak Kleene matrices, and the necessity operator is given a “weak” interpretation. Completeness and incompleteness results for some (axiomatic) systems are then established. Extensions of these modal logics in which figure “statability” operators are also examined.

This volume features essays about and by Paul Benacerraf, whose ideas have circulated in the philosophical community since the early nineteen sixties, shaping key areas in the philosophy of mathematics, the philosophy of language, the philosophy of logic, and epistemology. The book started as a worskhop held in Paris at the Collège de France in May 2012 with the participation of Paul Benacerraf. The introduction addresses the methodological point of the legitimate use of so-called “Princess Margaret Premises” in drawing philosophical (...) conclusions from Gödel’s first incompleteness theorem. The book is then divided into three sections. The first is devoted to an assessment of the improved version of the original dilemma of “Mathematical Truth” due to Hartry Field: the challenge to the platonist is now to explain the reliability of our mathematical beliefs given the very subject matter of mathematics, either pure or applied. The second addresses the issue of the ontological status of numbers: Frege’s logicism, fictionalism, structuralism, and Bourbaki’s theory of structures are called up for an appraisal of Benacerraf’s negative conclusions of “What Numbers Could Not Be.” The third is devoted to supertasks and bears witness to the unique standing of Benacerraf’s first publication: “Tasks, Super-Tasks, and Modern Eleatics” in debates on Zeno’s paradox and associated paradoxes, infinitary mathematics, and constructivism and finitism in the philosophy of mathematics. Two yet unpublished essays by Benacerraf have been included in the volume: an early version of “Mathematical Truth” from 1968 and an essay on “What Numbers Could Not Be” from the mid 1970’s. A complete chronological bibliography of Benacerraf’s work to 2016 is provided.Essays by Jody Azzouni, Paul Benacerraf, Justin Clarke-Doane, Sébastien Gandon, Brice Halimi, Jon Pérez Laraudogoitia, Mary Leng, Antonio Leòn-Sànchez and Ana Leòn-Mejía, Marco Panza, Fabrice Pataut, Philippe de Rouilhan, Andrea Sereni, and Stewart Shapiro.

The benefits of Artificial Intelligence (AI) in medicine are unquestionable and it is unlikely that the pace of its development will slow down. From better diagnosis, prognosis, and prevention to more precise surgical procedures, AI has the potential to offer unique opportunities to enhance patient care and improve clinical practice overall. However, at this stage of AI technology development it is unclear whether it will de-humanize or re-humanize medicine. Will AI allow clinicians to spend less time on administrative tasks and (...) technology related procedures and more time being present in person to attend to the needs of their patients? Or will AI dramatically increase the presence of smart technology in the clinical context to a point of undermining the humane dimension of the patient–physician relationship? In this brief commentary, we argue that technological solutions should be only integrated into clinical medicine if they fulfill the following three conditions: (1) they serve human ends; (2) they respect personal identity; and (3) they promote human interaction. These three conditions form the moral imperative of humanity. (shrink)

I give a semantic characterisation of a system for the logic of grounding similar to the system introduced by Kit Fine in his “Guide to Ground”, as well as a semantic characterisation of a variant of that system which excludes the possibility of what Fine calls ‘zero-grounding’.

Philosophers agree that an important part of our knowledge is acquired via testimony. One of the main objectives of social epistemology is therefore to specify the conditions under which a hearer is justified in accepting a proposition stated by a source. Non-reductionists, who think that testimony could be considered as an a priori source of knowledge, as well as reductionists, who think that another type of justification has to be added to testimony, share a common conception about children development. Non-reductionists (...) believe that infants and children are fundamentally gullible and their gullibility could be seen as an example for justifying testimony, while reductionists believe that this gullibility is merely an exception that should be taken into account. The objective of this paper is to review contemporary literature in developmental psychology providing empirical grounds likely to clarify this philosophical debate. What emerges from current research is a more elaborated vision of children’s attitude toward testimony. Even at a very young age, children do not blindly swallow information coming from testimony; doubtful or contradictory information is automatically screened by their cognitive system. Even if they are unable to give positive reasons for the acceptance of a given testimony, young children are not gullible. Such empirical findings tend to call into question the radical opposition between reductionism and non-reductionism. (shrink)

Professor Prawitz has made four claims in his talk. The first claim is that one should be able to generalize the intuitionistic theory of meaning already available for mathematical discourse to empirical discourse. Since each claim constitutes a step in an argument of a general form in favour of some new kind of antirealistically inclined theory of meaning (with a final pessimistic overtone), I shall go over each claim one by one, check whether the argument which links them in the (...) way described is sound, and assess on that basis the appropriateness of the project (and of the pessimism).

It is not the purpose of this article to evaluate the techno-scientific claims of the transhumanists. Instead, I question seriously the nature of the ethics and morals they claim can, or soon will, be manipulated artificially. I argue that while the possibility to manipulate human behavior via emotional processes exists, the question still remains concerning the content of morality. In other words, neural moral enhancement does not capture the fullness of human moral psychology, which includes moral capacity and moral content. (...) In this article, I revisit the debate between Hume and Kant concerning the role of emotions and reason in moral philosophy. I do so with reference to the work of philosopher Alasdair McIntyre. His moral philosophy has long stood as an essential text in virtue ethics, which constitutes the basis for my critique of the promise to engineer virtues (what I call “neural moral enhancement”). First, I outline three specific shifts that occurred in the history of Western moral philosophy in order to contextualize current debates on the nature of morality/moral agency. Second, I summarize MacIntyre's critique of contemporary moral philosophy and show its relevance to an assessment of neural moral enhancement. Finally I argue that moral neuroenhancement is a one-dimensional conceptualization of moral agency that does not reflect the fullness of human moral psychology. It envisions a world in which individual moral capacities will be enhanced and controlled but says nothing about the nature of the morality. (shrink)

The aim of this article is to explore in a systematic way the rationality of emotions elicited when we engage with works of fiction. I first lay out the approach to the emotions on which my discussion is premised. Next, I concentrate on two facets of emotional rationality—the first pertains to the relation between emotions and the mental states on which they are based, the second to the relation between emotions and the judgements and behaviour they elicit. These observations about (...) emotional rationality are then applied to emotions elicited by works of fiction. After having distinguished several families of emotions, I concentrate on what I call blob-emotions and emotions-for. I argue that, given their nature as direct responses to a restricted range of stimuli, blob-emotions are not irrational. As regards emotions-for fictional entities, I emphasize that a subject’s rationality shows in the way her emotions-for respond to evidence. On this basis, I discard an influential reason to think that emotions-for fictional entities are irrational. Finally, I offer an argument to conclude that they are typically correct and rational.

This paper presents a propositional version of Kit Fine's (quantified) logic for essentialist statements, provides it with a semantics, and proves the former adequate (i.e. sound and complete) with respect to the latter.

Many philosophers hold that physical laws have a unique modal status known as nomic necessity which is weaker than metaphysical necessity. This orthodox view has come into question in the past few decades. In particular, the metaphysical view known as essentialism has provided an argument that the laws of nature are necessary in the strongest possible sense. It seems obvious to many that at least some essentialist arguments in favor of the necessity of scientific claims are going to be sound. (...) For example, the view that claims like "water is H2O" are necessary has itself 2 become an orthodox view. However, the question of whether laws, like the law of conservation of energy, or the law of gravity, are necessary is far more contentious. Philosophers divide roughly into two camps, law necessitarians1 who hold that the laws are necessary in the strongest sense and contingency theorists who hold that they are at least in some sense contingent. One argument for the necessitarian position is via an essentialist theory of the transworld identity of properties. In this paper I defend such a theory of the identity of properties and its necessitarian consequences from one major criticism. To focus the paper, I center the discussion on a single critic, E. J. Lowe. In his book, The Four Category Ontology, he offers a criticism of the essentialist argument for necessitarianism via an analogy with other forms of transworld identity and intuitions about the contingency of the physical constants2. I undermine the usefulness of Lowe's analogy by examining the purposes of attributions of properties. I also show that the essentialist's position can allow it to accommodate the intuitions of contingency in a way that fits best with the purpose behind property attributions. (shrink)

Standard possible world semantics for propositional modal languages ignore truth-value gaps. However, simple considerations suggest that it should not be so. In Section 1, I identify what I take to be a correct truth-clause for necessity under the assumption that some possible worlds are incomplete (i.e., "at" which some propositions lack a truth-value). In Section 2, I build a world semantics, the semantics of TV-models, for standard modal propositional languages, which agrees with the truth-clause for necessity previously identified. Sections 3–5 (...) are devoted to systematic concerns. In particular, in Section 4, Prior’s system Q (propositional version) is given a TV-models semantics and proved adequate (i.e., sound and complete) with respect to it. (shrink)

Consider two standard quantified modal languages A and P whose vocabularies comprise the identity predicate and the existence predicate, each endowed with a standard S5 Kripke semantics where the models have a distinguished actual world, which differ only in that the quantifiers of A are actualist while those of P are possibilist. Is it possible to enrich these languages in the same manner, in a non-trivial way, so that the two resulting languages are equally expressive-i.e., so that for each sentence (...) of one language there is a sentence of the other language such that given any model, the former sentence is true at the actual world of the model iff the latter is? Forbes (1989) shows that this can be done by adding to both languages a pair of sentential operators called Vlach-operators, and imposing a syntactic restriction on their occurrences in formulas. As Forbes himself recognizes, this restriction is somewhat artificial. The first result I establish in this paper is that one gets sameness of expressivity by introducing infinitely many distinct pairs of indexed Vlach-operators. I then study the effect of adding to our enriched modal languages a rigid actuality operator. Finally, I discuss another means of enriching both languages which makes them expressively equivalent, one that exploits devices introduced in Peacocke (1978). Forbes himself mentions that option but does not prove that the resulting languages are equally expressive. I do, and I also compare the Peacockian and the Vlachian methods. In due course, I introduce an alternative notion of expressivity and I compare the Peacockian and the Vlachian languages in terms of that other notion. (shrink)

A fast growing family of ATPases has recently been highlighted. It was named the AAA family, for ATPases Associated to a variety of cellular Activities. The key feature of the family is a highly conserved module of 230 amino acids present in one or two copies in each protein. Despite extensive sequence conservation, the members of the family fulfil a large diversity of cellular functions: cell cycle regulation, gene expression in yeast and HIV, vesicle‐mediated transport, peroxisome assembly, 26S protease function (...) etc. In addition, several members of this family can be found in the same organism (up to 17 in S. cerevisiae). The contrast between functional diversity and structural conservation of the module, from archaebacteria to mammals, suggests that it plays an essential, but as yet unknown, role at key points of the cellular machinery. Two (non‐exclusive) such possibilities are: (1) ATP‐dependent proteasome function and (2) ATP‐dependent anchorage of proteins. Finally, the basic biochemical activity of the AAA module is still a matter of speculation, and we propose that it acts as an ATP‐dependent protein clamp. (shrink)

Ce texte a pour but de mettre en confrontation la conception ruyérienne de la philosophie avec la conception wittgensteinienne. L’opposition majeure consiste dans l’idée défendue par Ruyer selon laquelle on ne saurait concevoir ce qu’est l’esprit sans définir un domaine, intérieur au sujet, qu’on peut identifier avec sa subjectivité. Une telle idée est comprise par Ryle comme un mythe, celui de l’intériorité. Il y a en revanche une volonté commune (mais bien différente) à Ruyer et Wittgenstein de s’émanciper de la (...) science. Deux thèmes permettent alors de comparer les objectifs de Ruyer et ceux des philosophes wittgensteiniens : le thème des mythes en philosophie et celui de la traduction. (shrink)

Although G¨odel proved the first incompleteness theorem by intuitionistically respectable means, G¨odel’s formula, true although undecidable,seems to offer a counter-example to the general constructivist or anti-realistclaim that truth may not transcend recognizability in principle. It is arguedhere that our understanding of the formula consists in a knowledge of itstruth-conditions, that it is true in a minimal sense and, finally, that it is recognized as such given the consistencyand ω-consistency of P. The philosophical lesson to be drawn from G¨odel’sproof is that (...) our capacities for justification in favour of minimal truth exceedwhat is strictly speaking formally provable in P by means of an algorithm.

This paper studies the English poems of Richard Crashaw from a historicist and formalist perspective. It specifically considers Crashaw’s poetry in its religious but also intellectual and early scien­tific context to investigate the frequently overlooked influence of science on his poetry. Metaphors drawn from alchemy and particularly from the trans­formation of matter to achieve its purification and spiritualisation enrich the poet’s expression of mystical devotion to underline that access to the spiritual as well as mystical union with Christ are deeply (...) rooted in the devotee’s body. Representations of the earth as a chemical laboratory focus on materiality and corporality to emphasise the constant movement animating matter. A form of spiritual alchemy underscores Crashaw’s Christocentrism and references to the metamorphoses of matter consistently aim to express mystical union. A meta-poetic analysis eventually highlights a significant analogy between reading and alchemical processes in order to demonstrate the anagogical aim of Crashaw’s verse and the way his poems work on his reader’s heart to lift his soul. References to liquefaction, distillation or sublimation echo the published works of mystics but alchemical conceits based on symbolically evocative topoï and polysemic vocabulary reinforce the importance of the corporal in the expe­rience of mystical union.
