We have no reason to believe that reasons do not exist. Contra Bart Streumer’s recent proposal, this has nothing to do with our incapacity to believe this error theory. Rather, it is because if we know that if a proposition is true, we have no reason to believe it, then we have no reason to believe this proposition. From a different angle: if we know that we have at best misleading reasons to believe a proposition, then we have no reason (...) to believe it. This has two consequences. Firstly, coming close to believing the error theory is idle or pointless. Secondly, philosophers who argue that believing sweeping theories like determinism or physicalism is self-defeating because they are either false or believed for no reason pursue a worthwhile argumentative strategy. (shrink)

Here is a skeptical trilemma. We know that we are responsible. We do not know that determinism is false. Yet, if we do not know that determinism is false, we do not know that we are responsible. If we want to avoid the skeptical conclusion of rejecting the first claim, we ought to reject the third. It does not follow that compatibilism is true. But it follows that libertarianism, the view that we are responsible even though responsibility requires indeterminism, is (...) unknowable, at least for now. To see this, we need to compare different forms of skepticism and their response. (shrink)

Comme de nombreux penseurs antiques avant et après eux et contrairement à Socrate, Calliclès et Diogène ont déclaré avoir fondé leur éthique sur l’observation de la nature. Et pourtant, les deux discours normatifs qui sont tirés d’une nature que l’on pourrait a priori croire être la même sont on ne peut plus opposés. Calliclès croit que l’homme est appelé à dominer autrui ; Diogène pense plutôt qu’il doit se dominer lui-même ; le premier est un hédoniste débridé, le second croit (...) que le bonheur ne s’achète qu’au prix du sacrifice des désirs artificiels. Comment expliquer cette dichotomie ? Nous empruntons deux routes explicatives. D’abord, nous montrons que pour Calliclès et Diogène, la notion de nature non seulement diffère, mais est observée sous un angle différent. La première est celle des tyrans et de dieux anthropomorphes, la seconde, celle de petits animaux et de dieux autarciques. La première concerne la relation des hommes entre eux ; la seconde, celle de l’homme avec lui-même. Ensuite, nous exposons la différence des présupposés normatifs qui précèdent ou accompagnent l’observation de la nature ; nous contrastons, pour ce faire, les formes d’anticonventionnalisme et d’anti-intellectualisme défendues par Calliclès et Diogène. -/- SUMMARY. Like many ancient thinkers before and after them and contra Socrates, Callicles and Diogenes said they based their ethics on the observation of nature. And yet, the two normative discourses that are derived from nature that we might a priori believe to be the same could not be more opposed. Callicles believes that people are called to dominate others, Diogenes rather thinks people must dominate themselves. The first is an unbridled hedonist, the second believes that happiness can be bought only at the price of sacrificing artificial desires. How to explain this dichotomy? We take two explanatory routes. First, we show that for Callicles and Diogenes, the notion of nature not only differs but is observed from a different angle. The first one is the nature of tyrants and anthropomorphic gods, the second that of small animals and autarkic gods. The first focuses on the relationship between people, the second focuses on the relationship of a person with themselves. Secondly, we expose the difference in normative assumptions that precede or accompany the observation of nature; in order to do so, we contrast anticonventionalism and anti-intellectualism forms proper to both Callicles and Diogenes.

Free will sceptics deny the existence of free will, that is the command or control necessary for moral responsibility. Epicureans allege that this denial is somehow self-defeating. To interpret the Epicurean allegation charitably, we must first realise that it is propositional attitudes like beliefs and not propositions themselves which can be self-defeating. So, believing in free will scepticism might be self- defeating. The charge becomes more plausible because, as Epicurus insightfully recognised,there is a strong connection between conduct and belief—and so (...) between thecontent of free will scepticism (since it is about conduct) and the attitude of believing it. Second, we must realise that an attitude can be self- defeating relative to certain grounds. This means that it might be self-defeating to be a free will sceptic on certain grounds, such as the putative fact that we lack leeway or sourcehood. This charge is much more interesting because of the epistemic importance of leeway and sourcehood. Ultimately, the Epicurean charge of self-defeat fails. Yet, it delivers important lessons to the sceptic. The most important of them is that free will sceptics should either accept the existence of leeway or reject the principle that ‘“ought” implies “can”’. (shrink)

No one is responsible for their conduct because free will is an illusion, say some skeptics. Even when it seems that we have several options, we only have one. Hence, says the free will skeptic, we should reform our practices which involve responsibility attributions, such as punishment and blame. How seriously should we take this doctrine? Is it one that we could live by? One thorn in the side of the skeptic concerns deliberation. When we deliberate about what to do—what (...) film to go see, whom to befriend, which doctrine to follow—we must presume that our options are open to us. But then, every time that skeptics deliberate, they presume something which is incompatible with their doctrine, i.e. that they have several options. In a word, skeptics cannot deliberate qua skeptics. Some philosophers have responded that deliberators don’t have to presume that their options are open; they only have to presume that their choice will be efficacious. I argue that this proposal uses resources which, if they are available and successful, can be employed to refute skepticism. The upshot is that free will skeptics are pushing for a doctrine that is either false or in tension with deliberation. (shrink)

A version of the principle of alternate possibilities claims that one is only blameworthy for actions which one was able to avoid. Much of the discussion about PAP concerns Frankfurt’s counterexamples to it. After fifty years of refined debates, progress might seem hopeless. Yet, we can make headway by asking: “what’s our reason for believing PAP?” The best answer is this: lacking eligible alternatives—alternatives whose cost is not too high to reasonably opt for—is a good excuse. Yet, this principle is (...) subject to straightforward counterexamples, unless it is given an epistemicised reading. And in this latter case, it does not support PAP. So, PAP is unsupported, at least for now. (shrink)

Suppose I am a leeway sceptic: I think that, whenever I face a choice between two courses of action, I lack true alternatives. Can my practical deliberation be rational? Call this the Deliberation Question. This paper has three aims in tackling it. Its constructive aim is to provide a unified account of practical deliberation. Its corrective aim is to amend the way that philosophers have recently framed the Deliberation Question. Finally, its disputative aim is to argue that leeway sceptics cannot (...) deliberate entirely rationally about what to do, because of the connection between deliberating and deciding. (shrink)

This article contrasts Epicurus's and Diogenes the Cynic's respective views on acceptable desires. I emphasize their appeals to nature to legitimize or de-legitimize certain types of desires.

Diogène de Sinope et Calliclès affirment tirer leurs éthiques de l'observation de la nature. En cela, ils s'opposent explicitement à Socrate. Mais leur position est-elle une véritable forme de naturalisme ou un simple usage métaphorique? Ce texte défend la première option, après avoir montré que malgré leur ressemblance métaéthique, ces deux éthiques normatives sont radicalement opposées.

I offer an unorthodox argument for the thesis that prostitution is not just a normal job. It has the advantage of being compatible with the claim that humans should have full authority over their sexual life. In fact, it is ultimately the emphasis on this authority that leads the thesis that prostitution is a normal job to collapse. Here is the argument: merchants cannot (both legally and morally) discriminate whom they transact with on the basis of factors like the ethnicity (...) or the religion of their client; but if prostitutes are ‘sex merchants’, then they cannot (both legally and morally) discriminate whom they have sex with on the basis of these factors. Yet everyone should have the full discretionary power to refuse to have sex under any circumstances. (shrink)

Le solidarisme de Léon Bourgeois constitue une tentative convaincante de surmonter l’opposition traditionnelle entre libertés individuelles et justice sociale. Bourgeois tente de relever ce défi en faisant appel aux nouvelles découvertes scientifiques en sociologie comme en biologie. En bref, l’observation de la nature nous montrerait que les humains sont en rapport de solidarité les uns avec les autres. De ce fait, on pourrait tirer un devoir de solidarité que l’État serait à même d’imposer aux individus. Fonder une théorie politique sur (...) des théories scientifiques présente un double risque : d’une part, subir l’influence des biologistes collectivistes et de leur vision organiciste de la société ; d’autre part et surtout, se rendre coupable du sophisme naturaliste. Nous exposerons comment Bourgeois tombe initialement dans le piège du sophisme naturaliste avant de s’en extirper. Entre son texte Solidarité (1987) et son Essai d’une philosophie de la solidarité (1907), la progression est frappante. Au final, donc, Bourgeois nous semble présenter une théorie politique qui, tout en s’inspirant des sciences, ne s’y assujettit pas. (shrink)

Ce compte-rendu résume les quatre dimensions de la philosophie de l’ action défendue dans Action, Knowledge and Will : physique, éthique, psychologique et intellectuel. Cela dit, les deux contributions principales du livre recensé relèvent de liens entre les différentes dimensions de l’ action. Il s’agit d’une distinction et d’une connexion. Premièrement, Hyman croit qu’il faut distinguer la dimension éthique et la dimension physique de l’ action. Plus précisément, il pense que le concept de volonté et le concept de volontaire doivent (...) être différenciés du concept d’ action ou de celui d’agencité, et d’actif. Deuxièmement, Hyman nous propose de connecter la dimension intellectuelle de l’ action avec la connaissance en avançant une théorie de la connaissance comme étant l’habileté d’être guidé par des faits.

We study one way in which stable phenomena can exist in an NIP theory. We start by defining a notion of ‘pure instability’ that we call ‘distality’ in which no such phenomenon occurs. O-minimal theories and the p-adics for example are distal. Next, we try to understand what happens when distality fails. Given a type p over a sufficiently saturated model, we extract, in some sense, the stable part of p and define a notion of stable independence which is implied (...) by non-forking and has bounded weight. (shrink)

We show basic facts about dp-minimal ordered structures. The main results are: dp-minimal groups are abelian-by-finite-exponent, in a divisible ordered dp-minimal group, any infinite set has non-empty interior, and any theory of pure tree is dp-minimal.

In this article, we develop tame topology over dp-minimal structures equipped with definable uniformities satisfying certain assumptions. Our assumptions are enough to ensure that definable sets are tame: there is a good notion of dimension on definable sets, definable functions are almost everywhere continuous, and definable sets are finite unions of graphs of definable continuous “multivalued functions.” This generalizes known statements about weakly o-minimal, C-minimal, and P-minimal theories.

This paper has two parts. In the first one, we prove that an invariant dp-minimal type is either finitely satisfiable or definable. We also prove that a definable version of the -theorem holds in dp-minimal theories of small or medium directionality.In the second part, we study dp-rank in dp-minimal theories and show that it enjoys many nice properties. It is continuous, definable in families and it can be characterised geometrically with no mention of indiscernible sequences. In particular, if the structure (...) expands a divisible ordered abelian group, then dp-rank coincides with the dimension coming from the order. (shrink)

We study invariant types in NIP theories. Amongst other things: we prove a definable version of the [Formula: see text]-theorem in theories of small or medium directionality; we construct a canonical retraction from the space of [Formula: see text]-invariant types to that of [Formula: see text]-finitely satisfiable types; we show some amalgamation results for invariant types and list a number of open questions.

We prove in particular that, in a large class of dp-minimal theories including the p-adics, definable types are dense amongst nonforking types.

This collection of articles is an important milestone in the history of the study of time conceptions in Greek and Roman Antiquity. It spans from Homer to Neoplatonism. Conceptions of time are considered from different points of view and sources. Reflections on time were both central and various throughout the history of ancient philosophy. Time was a topic, but also material for poets, historians and doctors. Importantly, the contributions also explore implicit conceptions and how language influences our thought categories.

This work builds on previous papers by Hrushovski, Pillay and the author where Keisler measures over NIP theories are studied. We discuss two constructions for obtaining generically stable measures in this context. First, we show how to symmetrize an arbitrary invariant measure to obtain a generically stable one from it. Next, we show that suitable sigma-additive probability measures give rise to generically stable Keisler measures. Also included is a proof that generically stable measures over o-minimal theories and the p-adics are (...) smooth. (shrink)

We prove a couple of results on NTP2 theories. First, we prove an amalgamation statement and deduce from it that the Lascar distance over extension bases is bounded by 2. This improves previous work of Ben Yaacov and Chernikov. We propose a line of investigation of NTP2 theories based on S1 ideals with amalgamation and ask some questions. We then define and study a class of groups with generically simple generics, generalizing NIP groups with generically stable generics.

Let [Formula: see text] be a monster model of an arbitrary theory [Formula: see text], let [Formula: see text] be any tuple of bounded length of elements of [Formula: see text], and let [Formula: see text] be an enumeration of all elements of [Formula: see text]. By [Formula: see text] we denote the compact space of all complete types over [Formula: see text] extending [Formula: see text], and [Formula: see text] is defined analogously. Then [Formula: see text] and [Formula: see (...) text] are naturally [Formula: see text]-flows. We show that the Ellis groups of both these flows are of bounded size, providing an explicit bound on this size. Next, we prove that these Ellis groups do not depend on the choice of the monster model [Formula: see text]; thus, we say that these Ellis groups are absolute. We also study minimal left ideals of the Ellis semigroups of the flows [Formula: see text] and [Formula: see text]. We give an example of a NIP theory in which the minimal left ideals are of unbounded size. Then we show that in each of these two cases, boundedness of a minimal left ideal is an absolute property and that whenever such an ideal is bounded, then in some sense its isomorphism type is also absolute. Under the assumption that [Formula: see text] has NIP, we give characterizations of when a minimal left ideal of the Ellis semigroup of [Formula: see text] is bounded. Then we adapt the proof of Theorem 5.7 in Definably amenable NIP groups, J. Amer. Math. Soc. 31 609–641 to show that whenever such an ideal is bounded, a certain natural epimorphism 863–932]) from the Ellis group of the flow [Formula: see text] to the Kim–Pillay Galois group [Formula: see text] is an isomorphism. We also obtain some variants of these results, formulate some questions, and explain differences which occur when the flow [Formula: see text] is replaced by [Formula: see text]. (shrink)

We prove that in $\operatorname {NTP}_{\operatorname {2}}$ theories the dp-rank of a type can be witnessed by indiscernible sequences of tuples satisfying that type. If the type has dp-rank infinity, then this can be witnessed by singletons.

A theory [Formula: see text] is said to have exact saturation at a singular cardinal [Formula: see text] if it has a [Formula: see text]-saturated model which is not [Formula: see text]-saturated. We show, under some set-theoretic assumptions, that any simple theory has exact saturation. Also, an NIP theory has exact saturation if and only if it is not distal. This gives a new characterization of distality.

We prove (Proposition 2.1) that if $\mu$ is a generically stable measure in an NIP (no independence property) theory, and $\mu(\phi(x,b))=0$ for all $b$ , then for some $n$ , $\mu^{(n)}(\exists y(\phi(x_{1},y)\wedge \cdots \wedge\phi(x_{n},y)))=0$ . As a consequence we show (Proposition 3.2) that if $G$ is a definable group with fsg (finitely satisfiable generics) in an NIP theory, and $X$ is a definable subset of $G$ , then $X$ is generic if and only if every translate of $X$ does not (...) fork over $\emptyset$ , precisely as in stable groups, answering positively an earlier problem posed by the first two authors.

We prove that every ultraproduct of p-adics is inp-minimal. More generally, we prove an Ax-Kochen type result on preservation of inp-minimality for Henselian valued fields of equicharacteristic 0 in the RV language.

We show that any theory of tame henselian valued fields is NIP if and only if the theory of its residue field and the theory of its value group are NIP. Moreover, we show that if is a henselian valued field of residue characteristic \=p\) such that if \, depending on the characteristic of K either the degree of imperfection or the index of the pth powers is finite, then is NIP iff Kv is NIP and v is roughly separably (...) tame. (shrink)

We address the following question: Can we expand an NIP theory by adding a linear order such that the expansion is still NIP? Easily, if acl(A)= A for all A, then this is true. Otherwise, we give counterexamples. More precisely, there is a totally categorical theory for which every expansion by a linear order has IP. There is also an ω-stable NDOP theory for which every expansion by a linear order interprets pseudofinite arithmetic.

Le but de ce recueil est d’offrir des commentaires accessibles et introductifs aux textes classiques qu’ils accompagnent, en ouvrant des perspectives de discussion sur le thème du capitalisme. C’est en ce sens qu’Emmanuel Chaput lance le débat en commentant le texte de Pierre-Joseph Proudhon, « Qu’est-ce que la propriété ? ». Les textes de Karl Marx ne sont bien sûr pas laissés pour compte : Samuel-Élie Lesage s’engage fermement dans cette voie en discutant L’idéologie allemande de Karl Marx, Christiane (...) Bailey nous offre d’approcher différemment l’œuvre marxienne en abordant son traitement de la question animale dans des extraits du Manifeste du parti communiste et du Travail salarié et capital, et Mathieu Joffre-Lainé nous présente une analyse fine des questions proprement économiques du Capital. Abordant les alternatives au capitalisme dans la pensée de Léon Bourgeois, Éliot Litalien commente La Solidarité et Simon-Pierre Chevarie-Cossette s’attaque à l’analyse de l’Essai d’une philosophie de la solidarité. Enfin, en liant capitalisme, patriarcat et pouvoir politique, Tara Chanady propose une lecture du texte Du mariage et de l’amour de Emma Goldman. La conclusion de Marie-Eve Jalbert se situe dans une perspective contemporaine et critique en décortiquant la critique du socialisme avancée par Friedrich A. Hayek. (shrink)

This research focuses on the perceptions of research integrity held by administrative science faculty members in French-language universities in Québec. More specifically, the survey was conducted to isolate and analyse the opinions of the target group concerning the seriousness and frequency of various types of conduct generally associated with a lack of integrity among researchers, peer reviewers and editors (or other assessment supervisors), the causes attributed to research misconduct, and the solutions proposed. Its main interest is to encourage researchers to (...) reflect on the standards they would like to see introduced, based on their own statements concerning what they think and do about research integrity. Each of the 699 faculty members surveyed received a 91-item questionnaire by mail, and 136 completed and returned it. The results show, among other things, that the respondents did not take the question of research integrity lightly; in almost all cases, they considered the types of conduct studied to be at least moderately reprehensible and often very reprehensible. In addition, the same types of conduct were considered to be, or almost to be, moderately frequent. Causes were closely linked to the achievement of professional success. Solutions related to the promotion of publication quality instead of quantity and to the inclusion of at least one full session on research integrity in advanced programs were very clearly favoured. However, in all cases, the consensus did not appear to be very strong. The limits of the results are discussed, along with the recommendations and research possibilities to which they lead. (shrink)

Advances in artificial intelligence, as well as its increased presence in everyday life, have brought the emergence of many new phenomena, including an intriguing appearance of what seems to be a variant of body dysmorphic disorder, coined “Snapchat dysmorphia”. Body dysmorphic disorder is a DSM-5 psychiatric disorder defined as a preoccupation with one or more perceived defects or flaws in physical appearance that are not observable or appear slight to others. Snapchat dysmorphia is fueled by automated selfie filters that reflect (...) unrealistic sociocultural standard. In this paper, we discuss how body dysmorphic disorder and related body image distortions could arise, using the conceptual resources provided by the active inference framework. We suggest that these disorders involve dysfunctional self-modelling which entails maladaptive internalization of sociocultural preferences during adolescent identity formation. Identity formation is hereby described as cycles of interpersonal active inference that arbitrate between identity exploration and commitment. We propose that impaired self-modelling is unable to reduce interpersonal uncertainty during identity exploration, which, over time, degenerates into uncontrollable epistemic habits that isolate the body image from corrective sensory evidence. In light of these insights, we subsequently explore some of the consequences of image-centered social media platforms on the identity formation process. We conclude that heightened interpersonal uncertainty in this novel context could precipitate the onset of body dysmorphic disorder and related body image distortions, particularly when selfie filters are involved.

L'altérité est l'un des phénomènes les plus étudiés et l'un des concepts les plus utilisés au cours des trente dernières années, mais c'est aussi une notion des plus polysémiques et des plus controversées, jusque dans les usages idéologiques qu'on peut en faire aujourd'hui. Ce livre interroge les bases philosophiques, le contexte sociohistorique et la portée éthique et esthétique de ce phénomène ou de cette notion à la lumière de ses différentes valeurs. L'autre est à la fois l'étranger, exclu ou minorisé, (...) pour les études culturelles, l'un des pôles de la construction identitaire pour certaines théories du sujet, l'expression même de la Loi et du Symbolique pour d'autres, la figure emblématique de la responsabilité pour une certaine pensée éthique, le fondement de toute relation intersubjective et de tout dialogisme ou, plus radicalement encore, la manifestation de la nature essentiellement hétérogène de l'existence. Chaque fois, ce qui est en jeu concerne nos manières de vivre-ensemble et nos façons de faire et de créer. Les auteurs réunis dans cet ouvrage analysent les "politiques de l'altérité" que notre histoire impose ou propose comme choix de société et " les poétiques de l'autre" que les différentes pratiques artistiques, ancrées dans la mémoire et l'imaginaire collectifs, déploient comme possible ou comme alternative face à notre situation historique.
