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.

The main objective of this article is to capitalise on many years of research, and of practice, relating to the use of introspection in a research context, and thus to provide an initial outline description of introspection, while developing an introspection of introspection. After a description of the context of this research, I define the institutional conditions which would enable the renewal of introspection as a research methodology. Then I describe three aspects of introspective practice: 1) introspection as a process (...) of becoming aware, theorized through Husserl's model of consciousness modes; 2) introspection as recollection, through the model of retention and awakening in Husserl's theory of memory; 3) the use of universal descriptive categories for the description of all lived experiences, as a guide for skilled practice of introspection in research. Finally I examine the question of the validation of introspective data, suggesting a strong distinction between the ethical criterion and the epistemic criterion of truth. (shrink)

This volumes aim is to provide an introduction to Carnaps book from a historical and philosophical perspective, each chapter focusing on one specific issue. The book will be of interest not only to Carnap scholars but to all those interested in the history of analytical philosophy.

Johnson-Laird's mental models theory claims that reasoning is a semantic process of construction and manipulation of models in working memory of limited capacity. Accordingly, both a deduction and a given interpretation of a premise would be all the harder the higher the number of models they require. The purpose of the present experiment was twofold. First, it aimed to demonstrate that the interpretation of if...then conditional sentences in children (third, sixth, and ninth graders) evolves as a function of the number (...) of models the children can produce. We proposed a theory of conditional reasoning development that hypothesises a developmental trend of three successive levels of interpretations underlain by one, two, and then three models, i.e. conjunctive, biconditional, and conditional respectively. Second, we aimed to show that these different levels correlate with working memory capacities: the higher the working memory span, the higher the number of models underlying the conditional interpretation. These two hypotheses were verified, supporting the mental models theory. The results are compared with the rival theory of mental logic. (shrink)

Drawing on various resources and requirements (as expressed by Dewey, Wittgenstein, Sellars, and Brandom), this paper proposes an externalist view of conceptual mental episodes that does not equate them, even partially, with vehicles of any sort, whether the vehicles be located in the environment or in the head. The social and pragmatic nature of the use of concepts and conceptual content makes it unnecessary and indeed impossible to locate the entities that realize conceptual mental episodes in non-personal or subpersonal contentful (...) entities (vehicles). Persons, who engage in social practices of deontic scorekeeping (Brandom), and who are thus able to produce appropriate inferential behaviour, enact conceptual mental episodes and the basis of their supervenience.

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.

The aim of this work is to study complex ecological models exhibiting simple dynamics. We consider large scale systems which can be decomposed into weakly coupled subsystems. Perturbation Theory is used in order to get a reduced set of differential equations governing slow time varying global variables. As examples, we study the influence of the individual behaviour of animals in competition and predator-prey models. The animals are assumed to do many activities all day long such as searching for food of (...) different types. The degree of competition as well as the predation pressure are dependent upon these activities. Preys are more vulnerable when doing some activities during which they are very exposed to predators attacks rather than for others during which they are hidden. We study the effect of a change in the average individual behaviour of the animals on interspecific relationships. Computer simulations of the whole sets of equations are compared to simulations of the reduced sets of equations. (shrink)

Through a detailed study of Spinoza's concept of 'experience', Moreau shows how Spinoza extends the power of reason to capture the singularity of individuals: their lives, languages, passions and societies.

If stem cell-based therapies are developed, we will likely confront a difficult problem of justice: for biological reasons alone, the new therapies might benefit only a limited range of patients. In fact, they might benefit primarily white Americans, thereby exacerbating long-standing differences in health and health care.

This paper shows that the Clauser–Horne–Shimony–Holt test of locality of correlations which was originally designed to be used with binary observables can actually be used for any couples of quantum-like bounded continuous observables, and then for any experimental situation describable within the mathematical framework of quantum theory.

This article reports two studies investigating the relationship between emotional feelings and respiration. In the first study, participants were asked to produce an emotion of either joy, anger, fear or sadness and to describe the breathing pattern that fit best with the generated emotion. Results revealed that breathing patterns reported during voluntary production of emotion were (a) comparable to those objectively recorded in psychophysiological experiments on emotion arousal, (b) consistently similar across individuals, and (c) clearly differentiated among joy, anger, fear, (...) and sadness. A second study used breathing instructions based on Study 1's results to investigate the impact of the manipulation of respiration on emotional feeling state. A cover story was used so that participants could not guess the actual purpose of the study. This manipulation produced significant emotional feeling states that were differentiated according to the type of breathing pattern. The implications of these findings for emotion theories based on peripheral feedback and for emotion regulation are discussed. (shrink)

Based on an endorsement of the hypothesis of extended cognition , this paper proposes a criticism of the representationalist assumptions that still pertain to these contemporary models of cognition. I first rehearse some basic problems akin to any representationalist model of cognition, before proposing some more specific arguments directed against the necessity, the plausibility, and the coherence of the marriage between extended cognition and contemporary representationalism . Extended and distributed models of cognition have the resources to get rid of representationalism, (...) and they should better do it. Their adherence to representationalism might be an by-product of the extended character of the scientific study of cognition. (shrink)

As is often the case when scientific or engineering fields emerge, new concepts are forged or old ones are adapted. When this happens, various arguments rage over what ultimately turns out to be conceptual misunderstandings. At that critical time, there is a need for an explicit reflection on the meaning of the concepts that define the field. In this position paper, we aim to provide a reasoned framework in which to think about various issues in the field of distributed cognition. (...) We argue that both relevant concepts, distribution and cognition, must be understood as continuous. As it is used in the context of distributed cognition, the concept of distribution is essentially fuzzy, and we will link it to the notion of emergence of system-level properties. The concept of cognition must also be seen as fuzzy, but for a different reason: due to its origin as an anthropocentric concept, no one has a clear handle on its meaning in a distributed setting. As the proposed framework forms a space, we then explore its geography and visit famous landmarks. (shrink)

In order to account for how organisms can apprehend the contents of the external representations they manipulate in cognizing, the endorsement of representationalism fosters a situation of what I call cognitive overdetermination. I argue that this situation is problematic for the inclusion of these external representations in cognitive processing, as the hypothesis of extended cognition would like to have it. Since that situation arises from a commitment to representationalism (even minimal), it only affects the viability of representationalist versions of extended (...) cognition. (shrink)

En cet article nous montrons en premier lieu que la théorie de l'hexagone logique de Blanché n'est pas, comme il le pense, le résultat d'une réflexion philosophique, mais qu'elle relève véritablement de la logique scientifique, puisqu'elle s'insère tout naturellement dans la structure d'ensemble des liaisons uninaires de la logique trivalente des propositions. Cette démonstration nous conduit, en second lieu, à renverser le jugement défavorable que E. J. Lemmon avait porté sur la toute première ébauche de cette théorie, et ainsi à (...) déVelopper la logique modale dans le sens de Blanché plutôt que dans celui de von Wright. En troisième lieu, nous complétons l'application que fait Blanché de cette théorie de l'hexagone aux liaisons binaires de la logique bivalente des propositions, en intégrant en une seule structure tétrahexaédrique l'ensemble des seize liaisons binaires, lui-même s'étant contenté d'en grouper seulement dix en une espèce d'anneau bihexagonal.

The reissue of this work as a Routledge Classic brings some radical ideas to a new audience, and argues persuasively for a totally new way of reading.

A widely accepted thesis in the philosophy of language is that natural language proper names are rigid designators, and that they are so de jure, or as a matter of the “semantic rules of the language.” This paper questions this claim, arguing that rigidity cannot be plausibly construed as a property of name types and that the alternative, rigidity construed as a property of tokens, means that they cannot be considered rigid de jure; rigidity in this case must be viewed (...) as a pragmatic and not a semantic property.

La quatrième des Considérations inactuelles de Friedrich Nietzsche est emblématique en ce qu'elle présente la notion d'événement de façon dialectique. Participant au premier festival de Bayreuth durant l'été 1876, c'est à la fois en tant que spectateur, historien et philosophe, que Friedrich Nietzsche interprète l'événement comme un « cas » ou un symptôme, et saisit la volonté de Richard Wagner dans sa « chute », où le spectacle et la décadence sont les valeurs de la culture européenne et de l'Allemagne (...) moderne. De plus, d’une volonté analogue, et d’abord impressionné par la hauteur du compositeur et la puissance de son œuvre totale, c’est à partir d’un « pathos de la distance » que le philosophe va « transvaluer » le cas Wagner après Bayreuth et le faire advenir comme le nouvel événement d’une histoire critique dans laquelle il se comprend lui-même. Alors, c’est comme un « grand » événement que nous interprétons Friedrich Nietzsche à Bayreuth décrit comme la synthèse d’un processus à la fois civilisationnel et culturel. (shrink)

Our main results are: (A) It is consistent relative to a large cardinal that holds but fails. (B) If holds and are two infinite cardinals such that and λ carries a good scale, then holds. (C) If are two cardinals such that κ is λ‐Shelah and, then there is no good scale for λ.

We show a transfer principle for the property that all types realised in a given elementary extension are definable. It can be written as follows: a Henselian valued field is stably embedded in an elementary extension if and only if its value group is stably embedded in its corresponding extension, its residue field is stably embedded in its corresponding extension, and the extension of valued fields satisfies a certain algebraic condition. We show for instance that all types over the Hahn (...) field $$\mathbb {R}((\mathbb {Z}))$$ are definable. Similarly, all types over the quotient field of the Witt ring $$W(\mathbb {F}_p^{\text {alg}})$$ are definable. This extends a work of Cubides and Delon and of Cubides and Ye. (shrink)

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)

The aim of this work is to present aggregation methods of hierarchically organized systems allowing one to replace the initial micro-system by a macro-system described by a few global variables. We also study the relations between the fast micro-dynamics and the slow macro-dynamics which can produce global properties. Emergence corresponds to a bottom-up coupling that is the result effected by a micro-level at a macro-level. As an example, we present prey-predator models with different time scales in an heterogeneous environment. A (...) fast time scale is associated to the migration process on spatial patches and a slow time scale is associated to growth and interactions between the populations. Preys must go on spatial patches where resources are located and where predators can attack them. The efficiency of the predators to catch preys is patch dependent. Perturbation methods allow us to aggregate the initial system of differential equations for the patch sub-populations into a macro-system of two differential equations governing the total population densities. We study the case of density independent and density dependent migrations. In the latter case, we show that different functional responses can emerge in the macro prey-predator model as a result of the coupling between the slow and fast systems. (shrink)

Suppose that knowledge and ignorance are complements in the sense of being mutually exclusive: for person S and fact p, either S knows that p or is ignorant that p. Understood in this way, ignorance amounts to a lack or absence of knowledge: S is ignorant that p if and only if it is not the case that S knows that p. Let us call the thesis that knowledge and ignorance are opposites the “Complement Thesis”. In this article, I discuss (...) its deployment in an ingenious new argument advanced by Alvin Goldman and Erik Olsson (2009) which, if sound, establishes that there is a kind of knowledge that amounts to nothing more than true belief. I rebut their argument and in doing so delineate some important epistemological lessons brought to light by the contrast between ignorance and knowledge. (shrink)

In his early essay on transcendence of the ego, Sartre attempted to follow Husserl’s Logical Investigations and to draw the consequences of his phenomenological criticism of subjectivity. Both authors have emphasized the elusiveness of the self as a result of intentionality of consciousness. However, Sartre’s analysis of ego led him quite far from Husserl’s philosophical project, insofar as it was somehow already raising the question about the moral nature of the self, and was thus establishing the basis of the conception (...) of moral consciousness that has been displayed later in Being and Nothingness. This article stresses the importance of such a turn in Sartre’s philosophy, which reorients him from a strict description of consciousness toward a moral assessment of the structure of the self.

The importance given by historian and philosopher of science Georges Canguilhem to the role of practice, techniques, and experimentation in concept-formation was largely overlooked by commentators. After placing Canguilhem’s contributions within the larger history of historical epistemology in France, and clarifying his views regarding this expression, I re-evaluate the relation between concepts and experimental practices in Canguilhem’s philosophy of science. Drawing on his early writings on the relations between science and technology in the 1930s, on the Essai sur quelques problèmes (...) concernant le normal et le pathologique, and on La formation du concept de réflexe aux XVIIe et XVIIIe siècles, I argue that the formation and rectification of concepts in Canguilhem’s sense are intrinsically bound with the experimental, material, technical, and cultural contexts in which concepts are operationalized.

Alors que la narratologie prétendait dévoiler les structures du récit en général, Vincent Descombes, dans son livre sur Proust, affirme qu’une science conséquente de la littérature doit rendre compte de la manière particulière qu’a chaque genre littéraire de produire du sens. Nous présentons dans cet article une approche noétique des genres qui, tentant de dépasser l’opposition entre sémiologie et herméneutique, s’intéresse à la manière dont les structures symboliques créent des modes de pensée particuliers. En remarquant que les fondateurs de la (...) narratologie, sous couvert de fiction, ont en réalité analysé le seul genre romanesque, elle propose de repartir de leur travail pour mettre au jour le fonctionnement des synthèses diachronique et synchronique propres au roman. N’en restant pas à cette analyse des structures sémiotiques, la noétique procède à leur interprétation phénoménologique, et montre que le mode de pensée du roman est celui de ce que Hegel appelle l’expérience de la conscience.
