Les fouilles récentes dans la partie nord du site archéologique de Kition-Bamboula ont conduit à la découverte d’un puits tout à fait remarquable. Par sa forme tout d’abord, puisqu’il s’agit d’un puits à roue élévatrice d’eau, d’un type qui n’était jusqu’alors documenté, à Chypre, que pour des périodes plus récentes. Par son comblement ensuite, puisque ce dernier contenait, outre divers débris, un dépôt de trois enfants (périnatals) accompagnés de mobilier. Par sa date, enfin, puisqu’il atteste une occupation de la zone (...) au ive siècle apr. J.‑C., alors qu’on pensait le site abandonné. Cet article propose une étude complète du puits et de son comblement (à l’exception des restes fauniques, présentés dans un article séparé), que prolonge une réflexion sur le paysage urbain de Kition au début de l’Antiquité tardive.

In a previous article on cosmological arguments, I have put forward a few examples of complete infinite and circular explanations, and argued that complete non-wellfounded explanations such as these might explain the present state of the world better than their well-founded theistic counterparts (Billon, 2021). Although my aim was broader, the examples I gave there implied merely causal explanations. In this article, I would like to do three things: • Specify some general informative conditions for complete and incomplete non-wellfounded causal (...) explanations that can be used to assess candidate explanations and to generate new examples of complete non-wellfounded explanations. • Show that these conditions, which concern chains of causal explanations, easily generalize to chains of metaphysical, grounding explanations and even to chains involving other “determination relations” such as supervenience. • Apply these general conditions to the recent debates against the existence of nonwellfounded chains of grounds and show, with a couple of precise examples, that the latter can be complete, and that just like in the case of causal explanations, non-wellfoundedness can in fact be an aset rather than a liability.

According to what we will call subjectivity theories of consciousness, there is a constitutive connection between phenomenal consciousness and subjectivity: there is something it is like for a subject to have mental state M only if M is characterized by a certain mine-ness or for-me-ness. Such theories appear to face certain psychopathological counterexamples: patients appear to report conscious experiences that lack this subjective element. A subsidiary goal of this chapter is to articulate with greater precision both subjectivity theories and the (...) psychopathological challenge they face. The chapter’s central goal is to present two new approaches to defending subjectivity theories in the face of this challenge. What distinguishes these two approaches is that they go to great lengths to interpret patients’ reports at face value – greater length, at any rate, than more widespread approaches in the extant literature.

Depersonalization is a pathological condition consisting in a deep modification of the way things appear to a subject, leading him to feel estranged from his body, his actions, his thoughts, his mind and even from himself. In this article, I argue that the study of depersonalization raises three challenges for recent theories of the sense of bodily ownership. These challenges—which I call the centrality challenge, the dissociation challenge and the grounding challenge— thwart most of these theories and suggest that the (...) sense of bodily ownership hinges on a phenomenal mark of mineness that can not be accounted for in terms of our sensory, interoceptive, agentive, cognitive or affective dispositions and that is psychologically primitive. In short: that mineness is first. (shrink)

Computational reproducibility possesses its own dynamics and narratives of crisis. Alongside the difficulties of computing as an ubiquitous yet complex scientific activity, computational reproducibility suffers from a naive expectancy of total reproducibility and a moral imperative to embrace the principles of free software as a non-negotiable epistemic virtue. We argue that the epistemic issues at stake in actual practices of computational reproducibility are best unveiled by focusing on software as a pivotal concept, one that is surprisingly often overlooked in accounts (...) of reproducibility issues. Software is not only about designing and coding but also about maintaining, supporting, distributing, licensing, and governance; it is not only about developers but also about users. We focus on openness debates among computational chemists involved in molecular modeling software packages as empirical grounding for our argument. We then identify and analyse four epistemic characteristics as key to the role of software in computational reproducibility. (shrink)

Depersonalization consists in a deep modification of the way things appear to a subject, leading him to feel estranged from his body, his actions, his thoughts, and his mind, and even from himself. Even though, when it was discovered at the end of the 19th century, this psychiatric condition was widely used to probe certain aspects of bodily awareness, and more specifically the sense of bodily ownership (SBO), it has been strangely neglected in contemporary debates. In this chapter, I argue (...) that because of three specific features, depersonalization raises some important challenges for current theories of the SBO. The first feature — call it “generality” — is that depersonalization does not only affect the sense of bodily ownership but also, typically, the sense of ``mental ownership’’ (SMO), the sense of agency or ``action ownership’’ (SOA), and the subject’s core sense of herself (CSS), that is, her awareness of herself as an I. The second feature is that except for the symptoms of depersonalization, depersonalized patients are hard to distinguish, psychologically, from normal subjects. This makes it hard to find psychological features that might explain their condition. The last feature, call it “fundamentality” is that the psychological features that do seem abnormal among depersonalized patients seem more likely to be explained by depersonalization than to explain it. These three features raise three challenges — the centrality challenge, the dissociation challenge, and the grounding challenge. Taken together, I will argue, these challenges suggest that the SBO depends on a form of phenomenal “mineness” that would mark my mental states as mine and that cannot be accounted for in sensorimotor, cognitive, or even affective terms. A phenomenal mineness that indeed seems to be psychologically primitive, and only accountable in neurophysiological terms. (shrink)

Using emotional film clips is one of the most popular and effective methods of emotion elicitation. The main goal of the present study was to develop and test the effectiveness of a new and comprehensive set of emotional film excerpts. Fifty film experts were asked to remember specific film scenes that elicited fear, anger, sadness, disgust, amusement, tenderness, as well as emotionally neutral scenes. For each emotion, the 10 most frequently mentioned scenes were selected and cut into film clips. Next, (...) 364 participants viewed the film clips in individual laboratory sessions and rated each film on multiple dimensions. Results showed that the film clips were effective with regard to several criteria such as emotional discreteness, arousal, positive and negative affect. Finally, ranking scores were computed for 24 classification criteria: Subjective arousal, positive and negative affect (derived from the PANAS; Watson & Tellegen, 1988), a positive and a negative affect scores derived from the Differential Emotions Scale (DES; Izard et al., 1974), six emotional discreteness scores (for anger, disgust, sadness, fear, amusement and tenderness), and 15 “mixed feelings” scores assessing the effectiveness of each film excerpt to produce blends of specific emotions. In addition, a number of emotionally neutral film clips were also validated. The database and editing instructions to construct the film clips have been made freely available in a website. (shrink)

Patients suffering from the Cotard syndrome can deny being alive, having guts, thinking or even existing. They can also complain that the world or time have ceased to exist. In this article, I argue that even though the leading neurocognitive accounts have difficulties meeting that task, we should, and we can, make sense of these bizarre delusions. To that effect, I draw on the close connection between the Cotard syndrome and a more common condition known as depersonalisation. Even though they (...) are not delusional, depersonalised patients seem to have experiences that are quite similar to those of Cotard patients. I argue that these experiences are essentially characterised by a lack of subjective character and of two other structural features of experience, which I call ‘the present character’ and ‘the actual character’. Cotard's nihilistic delusions simply consist in taking these anomalous experiences at face value. (shrink)

This paper focuses on one particular case that connects climate justice and climate economics. Its contribution is twofold. First, it aims at providing a sound normative foundation for carbon pricing mechanisms around the notions of a ‘right to energy’, the ‘duty not-to-harm’ and an argument for ‘restricted compensation’. Second, it identifies the normative elements from theories of climate justice that should guide the design of market-based instruments for climate change mitigation. This will cast light on the particular moral relevance of (...) the act of internalizing a negative externality and of the funds generated by putting a price on carbon. (shrink)

Several advocates of the lively field of “metaphysics of science” have recently argued that a naturalistic metaphysics should be based solely on current science, and that it should replace more traditional, intuition-based, forms of metaphysics. The aim of the present paper is to assess that claim by examining the relations between metaphysics of science and general metaphysics. We show that the current metaphysical battlefield is richer and more complex than a simple dichotomy between “metaphysics of science” and “traditional metaphysics”, and (...) that it should instead be understood as a three dimensional “box”, with one axis distinguishing “descriptive metaphysics” from “revisionary metaphysics”, a second axis distinguishing a priori from a posteriori metaphysics, and a third axis distinguishing “commonsense metaphysics”, “traditional metaphysics” and “metaphysics of science”. We use this three-dimensional figure to shed light on the project of current metaphysics of science, and to demonstrate that, in many instances, the target of that project is not defined with enough precision and clarity.

In this paper, we put forward a new account of emergence called “transformational emergence”. Such an account captures a variety of emergence that can be considered as being diachronic and weakly ontological. The fact that transformational emergence actually constitutes a genuine form of emergence is motivated. Besides, the account is free of traditional problems surrounding more usual, synchronic versions of emergence, and it can find a strong empirical support in a specific physical phenomenon, the fractional quantum Hall effect, which has (...) long been touted as a paradigmatic case of emergence.

This is a commentary on Andrea Lavazza and Murilo Vilaça's article "Human Extinction and AI: What We Can Learn from the Ultimate Threat" (Lavazza & Vilaça, 2024). I discuss the potential concern that their proposal to create artificial successors to "insure" against the tragedy of human extinction might mean being too quick to accept that catastrophic prospect as inevitable, rather than single-mindedly focusing on avoiding it. I also consider the question of the value that we might reasonably assign to such (...) a future of artificial successors under the assumption that they do not enjoy phenomenal consciousness.

In their target article, Kammerer and Frankish (K&F) wonder what forms introspection could take in non-human animals, enhanced humans, artificial intelligences, and aliens. In this short note, I focus on disordered or neurodiverse minds. More specifically, I assess a claim that has often been made more or less implicitly to the effect that, in virtue of their conditions, people with schizophrenia or depersonalization disorder have superior introspective abilities that allow them to discern some important but normally hidden characteristics of our (...) experiences — call this the superintrospectionitis thesis. In the course of my argumentation, I introduce distinctions and questions concerning the nature of the architecture and the function of introspection that might enrich K&F's framework. (shrink)

Ttler=‘Ttler is true’ says of itself that it is true. It is a truth-teller. I argue that we have equally telling arguments (i) to the effect that all truth-tellers must have the same truth-value (ii) and the effect that truth-tellers differ in truth-value. This is what I call the Truth-Tellers paradox. This paradox stems from the fact that the truth-value of a truth-teller like Ttler should be determined by the fact that it says of itself that it is true (which (...) entails (i)) but that it cannot be determined by that fact (as witnessed by (ii)). The Truth-Tellers paradox resem- bles the classical semantic paradoxes like the Liar. In both cases, a form of self-reference allows us to derive a contradiction from oth- erwise plausible semantic and logical principles. Furthermore the Truth-Tellers paradox can be formulated without using sentences which are in an intuitive sense ungrounded, it thus severs the link, almost universally taken for granted, between the semantic para- doxes and ungroundedness. Finally, some classical solutions to the Liar do not generalize to the Truth-Tellers paradox. (shrink)

This study focuses on comparison of perceptions of ethical business cultures in large business organizations from four largest emerging economies, commonly referred to as the BRICs (Brazil, Russia, India, and China), and from the US.

The study found significant differences among BRIC countries, with respondents from India and Brazil providing more favorable assessments of ethical cultures of their organizations than respondents from China and (...) Russia. Overall, highest mean scores were provided by respondents from India, the US, and Brazil. There were significant similarities in ratings between the US and Brazil. (shrink)

Consider an infinite series whose items are each explained by their immediate successor. Does such an infinite explanation explain the whole series or does it leave something to be explained? Hume arguably claimed that it does fully explain the whole series. Leibniz, however, designed a very telling objection against this claim, an objection involving an infinite series of book copies. In this paper, I argue that the Humean claim can, in certain cases, be saved from the Leibnizian “infinite book copies” (...) objection, and that this provides an interesting way to defuse some cosmological arguments for the existence of God and to give a non-theistic but complete explanation of the Universe. In the course of my argumentation, I also show that circular explanations can be “self-explanatory” as well: explaining two items by each other can explain the couple of items tout court. (shrink)

Descartes was certain that he was thinking and he was accordingly certain that he existed. Like Descartes, we seem to be more certain of our thoughts and our existence than of anything else. What is less clear is the reason why we are thus certain. Philosophers throughout history have provided different interpretations of the cogito, disagreeing both on the kind of thoughts it characterizes and on the reasons for its cogency. According to what we may call the empiricist interpretation of (...) the cogito, I can only claim to be certain of having experiences, and this certainty, as well as that of my own existence, stems from their phenomenal and subjective character. According to rationalist interpretations, on the other hand, I am certain of having some self-reflexive propositional attitudes, and this certainty derives from their rational features. Psychiatric patients suffering from acute forms of depersonalization or of the Cotard syndrome often doubt that they think and exist, and might even believe that they don't. I argue that their study allows us to favor the empiricist interpretation of the cogito. (shrink)

Basic self-awareness is the kind of self-awareness reflected in our standard use of the first-person.

Even though it has been neglected since then, depersonalization has been extensively studied, more than a century ago, and used as probe for understanding the nature and the causal mechanisms of basic self-awareness. In this paper, (...) I argue that depersonalized patients indeed have an impaired basic self-awareness, and that their study allows us both to favor one specific theory of basic self-awareness and to understand what is wrong with its rivals. According to the favored theory, which I call Cartesian, we are basically self-aware in virtue of being acquainted with ourselves through introspection. (shrink)

The concept of genidentity has been proposed as a way to better understand identity through time, especially in physics and biology. The genidentity view is utterly anti-substantialist in so far as it suggests that the identity of X through time does not presuppose whatsoever the existence of a permanent “core” or “substrate” of X. Yet applications of this concept to real science have been scarce and unsatisfying. In this paper, our aim is to show that a well-defined concept of functional (...) genidentity can be crucial to shed light on identity through time in classical physics and especially in biology. Finally, we show that understanding identity on the basis of continuity suggests a move towards an ontology of processes. (shrink)

One objection to enhancement technologies is that they might lead us to live inauthentic lives. Memory modification technologies (MMTs) raise this worry in a particularly acute manner. In this paper I describe four scenarios where the use of MMTs might be said to lead to an inauthentic life. I then undertake to justify that judgment. I review the main existing accounts of authenticity, and present my own version of what I call a “true self” account (intended as a complement, rather (...) than a substitute, to existing accounts). I briefly describe current and prospective MMTs, distinguishing between memory enhancement and memory editing . Moving then to an assessment of the initial scenarios in the light of the accounts previously described, I argue that memory enhancement does not, by its very nature, raise serious concerns about authenticity. The main threat to authenticity posed by MMTs comes, I suggest, from memory editing. Rejecting as inadequate the worries about identity raised by the President’s Council on Bioethics in Beyond Therapy , I argue instead that memory editing can cause us to live an inauthentic life in two main ways: first, by threatening its truthfulness, and secondly, by interfering with our disposition to respond in certain ways to some past events, when we have reasons to respond in such ways. This consideration allows us to justify the charge of inauthenticity in cases where existing accounts fail. It also gives us a significant moral reason not to use MMTs in ways that would lead to such an outcome. (shrink)

David Chalmers a récemment soutenu que la réalité virtuelle est réelle, plutôt que fictionnelle. Dans cet article, j’examine les implications ontologiques de ce « réalisme virtuel ».

Je présente ensuite plusieurs objections à cette ontologie algorithmique. Tant que celles-ci ne sont pas réglées, la question de l’identité des mondes et des objets virtuels reste encore (...) en suspens. (shrink)

This paper considers the medium of videogames from a goodmanian standpoint. After some preliminary clarifications and definitions, I examine the ontological status of videogames.

Drawing on Nelson Goodman and Catherine Elgin's works, I suggest that the best model to defend videogame cognitivism appeals to the notion of understanding.

Many philosophers regard the persistence of philosophical disputes as symptomatic of overly ambitious, ill-founded intellectual projects. There are indeed strong reasons to believe that persistent disputes in philosophy (and more generally in the discourse at large) are pointless. We call this the pessimistic view of the nature of philosophical disputes. In order to respond to the pessimistic view, we articulate the supporting reasons and provide a precise formulation in terms of the idea that the best explanation of persistent disputes entails (...) that they are pointless. We then show how to answer the pessimistic argument. Taking a well-known mathematical controversy as our paradigm example, we argue that some persistent disputes reflect substantive disagreements at the “meta-analytic” level, i.e., disagreements about the best way, among quite different candidates, to understand the topic at issue, and the best associated cluster of analytic truths one should accept concerning it. Moreover, our concrete example shows that such meta-analytic disagreements can in principle be settled and yield a genuine theoretical (as opposed to merely pragmatic) breakthrough. We conclude optimistically that persistent disputes can be an important means of fostering epistemic progress. (shrink)

An important challenge in bilingualism research is to understand the mechanisms underlying sentence processing in a second language and whether they are comparable to those underlying native processing. Here, we focus on verb-particle constructions (VPCs) that are among the most difficult elements to acquire in L2 English. The verb and the particle form a unit, which often has a non-compositional meaning (e.g., look up or chew out), making the combined structure semantically opaque. However, bilinguals with higher levels of English proficiency (...) can develop a good knowledge of the semantic properties of verb-particle constructions (Blais and Gonnerman, 2013). A second difficulty is that in a sentence context, the particle can be shifted after the direct object of the verb, (e.g., The professor looked it up). The processing is more challenging when the object is long (e.g. The professor looked the student’s last name up.). This shifted structure favors syntactic processing at the expense of VPC semantic processing. We sought to determine whether or not bilinguals’ reading time (RT) patterns would be similar to those observed for native monolinguals (Gonnerman and Hayes, 2005) when reading VPCs in sentential contexts. French-English bilinguals were tested for English language proficiency, working memory and explicit VPC semantic knowledge. During a self-paced reading task, participants read 78 sentences with verb-particle constructions that varied according to parameters that influence native speakers’ reading dynamics: verb-particle transparency, particle adjacency and length of the object noun phrase (NP; 2, 3, or 5 words). RTs in a critical region that included verbs, NPs and particles were measured. Results revealed that RTs were modulated by participants’ English proficiency, with higher proficiency associated with shorter RTs. Examining participants’ explicit semantic knowledge of VPCs and working memory, only readers with more native-like knowledge of VPCs and a high working memory presented RT patterns that were similar to those of monolinguals. Therefore, given the necessary lexical and computational resources, bilingual processing of novel structures at the syntax-semantics interface follows the principles influencing native processing. The findings are in keeping with theories that postulate similar representations and processing in L1 and L2 modulated by processing difficulty. (shrink)

Gilbert and colleagues are to be commended for drawing our attention to the need for a sounder empirical basis, and for more careful reasoning, in the context of the neuroethics debate on Deep Brain Stimulation (DBS) and its potential impact on the dimensions of personality, identity, agency, authenticity, autonomy and self (PIAAAS). While acknowledging this, this extended commentary critically examines their claim that the real-world relevance of the conclusions drawn in the neuroethics literature is threatened by the fact that the (...) concepts at the center of the discussion have “weak empirical grounding”. First, I show that while some possible understandings of multifaceted concepts like identity, authenticity and autonomy may indeed be unsuitable for a purely empirical inquiry, this is not the case of all of them. Secondly, I call into question the authors’ apparent suggestion that reliance on constructs involving an irreducibly normative dimension makes for a suboptimal state of affairs, and that they should ideally be replaced with substitutes taken from the language of neuroscience or social science in order to ensure an adequate empirical grounding for the debate. Such a suggestion, I argue, commits the authors to a controversial reductionist view in metaethics that the valid empirical concerns they raise in the rest of their article do not presuppose, and which could potentially us lead to lose sight of important ethical considerations.

This chapter introduces the main issues and themes of the volume. Approaches to individuality from metaphysics and philosophy of science are contrasted. Recent philosophical developments regarding concepts of biological and physical individuality are exposed.

Five main divergences are identified: the centrality of part-whole questions, the issue of identical individuals, the importance of the Principle of the Identity of Indiscernibles and, (...) finally, the importance of structuralist concerns. At the end of the chapter, the structure of the book is explained in detail. (shrink)

In this article I interpret John Rawls’s concept of the original position as a spiritual exercise. In addition to the standard interpretation of the original position as an expository device to select principles of justice for the fundamental institutions of society, I argue that Rawls also envisages it as a “spiritual exercise”: a voluntary personal practice intended to bring about a transformation of the self. To make this argument, I draw on the work of Pierre Hadot, a philosopher and classicist, (...) who introduced the idea of spiritual exercises as central to ancient and modern conceptions of philosophy. By reading Rawls alongside Hadot, this article portrays Rawls as a thinker deeply concerned with the question of how subjects can lead more just and fulfilling lives. It also proposes that the original position as a spiritual exercise can help defend liberalism as a social and political doctrine. (shrink)

Authenticity has recently emerged as an important issue in discussions of mental disorder. We show, on the basis of personal accounts and empirical studies, that many people with psychological disorders are preoccupied with questions of authenticity. Most of the data considered in this paper are from studies of people with bipolar disorder and anorexia nervosa. We distinguish the various ways in which these people view the relationship between the disorder and their sense of their authentic self. We discuss the principal (...) modern ac-counts of authenticity within the analytic philosophical tradition. We argue that accounts based on autonomous, or wholehearted, endorsement of personal characteris-tics fail to provide an adequate analysis of authenticity in the context of mental disorder. Significant elements of true self accounts of authenticity are required. The concept of authenticity is a basic one that can be of particular value, in the context of self-development, to people with mental disorder and to others experiencing substantial inner conflict.

I first propose to distinguish between two kinds of external validity inferences, predictive and explanatory. I then argue that we have a satisfactory answer to the question of the conditions under which predictive external validity inferences are good. If this claim is correct, then it has two immediate consequences: First, some external validity inferences are deductive, contrary to what is commonly assumed. Second, Steel’s requirement that an account of external validity inference break what he calls the ‘Extrapolator’s Circle’ is misplaced, (...) at least when it comes to predictive external validity inferences.

Natural modalities are often analysed from an abstract point of view where they are associated with putative laws of nature. However, the way possibilities are represented in physics is more complex. Lagrangian mechanics, for instance, involves two different layers of modalities: kinematical and dynamical possibilities. This paper examines the status of these two layers, both in the classical and quantum case. The quantum case is particularly problematic: we identify four possible interpretive options. The upshot is that a close inspection of (...) the way possibilities are represented in physics could lead to new ways of thinking about natural modalities. (shrink)

Most paradoxes of self-reference have a dual or ‘hypodox’. The Liar paradox (Lr = ‘Lr is false’) has the Truth-Teller (Tt = ‘Tt is true’). Russell’s paradox, which involves the set of sets that are not self-membered, has a dual involving the set of sets which are self-membered, etc. It is widely believed that these duals are not paradoxical or at least not as paradoxical as the paradoxes of which they are duals. In this paper, I argue that some paradox’s (...) duals or hypodoxes are as paradoxical as the paradoxes of which they are duals, and that they raise neglected and interestingly different problems. I first focus on Richard’s paradox (arguably the simplest case of a paradoxical dual), showing both that its dual is as paradoxical as Richard’s paradox itself, and that the classical, Richard-Poincaré solution to the latter does not generalize to the former in any obvious way. I then argue that my argument applies mutatis mutandis to other paradoxes of self-reference as well, the dual of the Liar (the Truth-Teller) proving paradoxical. (shrink)

According to David Chalmers, the virtual entities found in Virtual Reality (VR) and Augmented Reality (AR) environments instantiate virtual properties of a specific kind. It has recently been objected that such a view (i) can’t extend to all types of properties; (ii) leads to a proliferation of property-types; (iii) implausibly ascribes massive errors to VR and AR users; and (iv) faces an analogue of Jackson’s “many-property problem”. My first objective here is to show that advocates of virtual properties can deal (...) with each of these objections. The other goal of this paper is to examine the consequences of Chalmers’ theory in the particular case of AR. If we countenance virtual properties, AR highlights that non-virtual objects can possess both non-virtual and virtual properties. With AR, it also appears that a same non-virtual object can have different and even incompatible properties across augmented environments. Lastly, considering properties in light of AR highlights the risk of an “augmented solipsism”, and calls forth interesting questions about the persistence conditions of non-virtual objects in AR environments.

Cauchy’s contribution to the foundations of analysis is often viewed through the lens of developments that occurred some decades later, namely the formalisation of analysis on the basis of the epsilon-delta doctrine in the context of an Archimedean continuum. What does one see if one refrains from viewing Cauchy as if he had read Weierstrass already? One sees, with Felix Klein, a parallel thread for the development of analysis, in the context of an infinitesimal-enriched continuum. One sees, with Emile Borel, (...) the seeds of the theory of rates of growth of functions as developed by Paul du Bois-Reymond. One sees, with E. G. Björling, an infinitesimal definition of the criterion of uniform convergence. Cauchy’s foundational stance is hereby reconsidered. (shrink)

Scrutiny of the epigram’s meter, language, literary conventions, and the handwriting of the scribe who copied it into the manuscript point to a tenth-century date not only for the manuscript but also (...) for the epigram itself and make it possible to situate the epigram, and with it the alchemical manuscript that contains it, within the mainstream of middle Byzantine elite culture.

A strongly determined extension of p over A assigns, for any model M )- A, a type q S extending p such that, if realises q, then any elementary partial map M → M which fixes acleq pointwise is elementary over . This gives a crude notion of independence which arises very frequently. Examples are provided of many different kinds of theories with strongly determined (...) types, and some without. We investigate a notion of multiplicity for strongly determined types with applications to ‘involved’ finite simple groups, and an analogue of the Finite Equivalence Relation Theorem. Lifting of strongly determined types to covers of a structure is discussed, and an application to finite covers is given. (shrink)

Le pronom tonique 'soi' ne pose pas de problème particulier dans les expressions comme 'prendre soin de soi', 'compter sur soi' ou 'être hors de soi'. Mais parler d'un 'soi', c'est aller au-delà de la réalité grammaticale et supposer une identité personnelle à travers la diversité des expériences. Or, l'idée de soi et la croyance en l'identité personnelle ont été mises en question par David Hume, dont les arguments résonnent toujours dans la philosophie (...) contemporaine. Le but de ce livre est double : montrer, en historiens de la philosophie, de quelle façon le philosophe britannique a répondu à ces problèmes, et évaluer la fécondité de ces résultats pour les sciences de l'esprit."--Page 4 of cover.
