We introduceself-divisibleultrafilters, which we prove to be precisely those$w$such that the weak congruence relation$\equiv _w$introduced by Šobot is an equivalence relation on$\beta {\mathbb Z}$. We provide several examples and additional characterisations; notably we show that$w$is self-divisible if and only if$\equiv _w$coincides with the strong congruence relation$\mathrel {\equiv ^{\mathrm {s}}_{w}}$, if and only if the quotient$(\beta {\mathbb Z},\oplus )/\mathord {\mathrel {\equiv ^{\mathrm {s}}_{w}}}$is a profinite group. We also construct an ultrafilter$w$such that$\equiv _w$fails to be symmetric, and describe the interaction between the (...) aforementioned quotient and the profinite completion$\hat {{\mathbb Z}}$of the integers.

This longitudinal study explored patterns of basic psychological needs and self-determined motivation, as well as its association with the teaching style and the physical activity enjoyment in a group of students. The sample consisted of 200 secondary education students (105 girls and 95 boys) aged 11 to 13 years (M= 12.65,SD= 0.79) at the start of the study. Students were assessed twice in a 22 month-period. Descriptive analyses were conducted between major variables at both time points, and to explore the (...) number and nature of clusters, we relied on latent profile analysis. The statistical analyses showed three different patterns: downward, stable and upward, with different outcomes and determinants. The downward pattern was associated with more negative enjoyment and a controlling style, while the upward pattern with more positive enjoyment and autonomy support. This study, which was based on a person-centered approach, provided a bigger picture of the interplay between autonomy, competence, relatedness, self-determined motivation, autonomy/control support, and physical activity enjoyment.

"En los últimos ocho años, hemos pasado de celebrar la posibilidad de una participación de la gente común en la política a casi dimitir de ella en favor de una visión anacrónicamente tecnócrata. ¿Cómo salir de la crisis de la democracia? Necesitamos distancia histórica para comprender que existen otras maneras de plantear el gobierno del pueblo. Necesitamos, también, claridad acerca de cuál es el mecanismo de la democracia que queremos poner en práctica.

A partir del análisis de algunas cuestiones hermenéuticas en la película Edipo rey, se defiende que uno de los aspectos centrales de la crítica a la sociedad de Pasolini es el allanamiento de la propiedad simbólica. Con ello, en este trabajo nos referiremos a la homologación consecuente de la sociedad de consumo que se manifiesta como una pérdida de lo sagrado. En esta línea, se analizan algunas cuestiones teóricas a propósito del pensamiento de Pasolini sobre el cine y se sostiene (...) que ese allanamiento de la propiedad simbólica es una condición de la posibilidad de “lo político” en nuestro tiempo.

This paper presents a foundation of the intellectual artefact “hermeneutic concept” based on an interpretation of the “Deduction of pure aesthetic judgment” of the third Kantian Critique. Since the denomination for this artefact and the first characterization is found in a Heidegger course, I will proceed by offering the context of discussion in which it arises, namely, the Heideggerian interpretation of the Kantian transcendental schematism. Then, I will give the interpretation of the Deduction that allows us the foundation of the (...) “hermeneutic concept” and, once the route of that foundation is completed, two reading hypothesis will be outlined, one for the place of the third Kantian Critique in Heidegger’s work and another for the aesthetics in general and the Kantian aesthetic in particular.

This article carried out an analysis from the hermeneutical category of the symbol in the novel Blindness by José Saramago, following Paul Ricoeur, in which the symbols of sin, stain and guilt were chosen to be developed after defining the relevance and the impact of the category of analysis on current situations in our society. Making use not only of the texts referring to Ricoeur's hermeneutics, but also of The Symbolic of Evil, a conceptual journey is proposed to elucidate how (...) the senses and meanings of the symbols of evil are configured in our culture and, through this understanding, address the situation of the symbolic apparatus of Saramago's novel. Carrying out an analysis of these hermeneutical categories in a novel such as Blindness becomes the opportunity to show a different meaning and sense of a novel that has clearly shown its relevance in previous times and that today, in the middle of a pandemic, invites us to rethink that world and to face the fact of understanding our own blindness and the blindness of the world in the midst of a dizzying speed that requires us to assume our reality in another way. In the words of Ricoeur, the symbol gives food for thought and it is time for us to think through our own symbols about the reality that is presented to us in Saramago's novel and to extrapolate it to the realities that are configured every day in our Western world.

Partiendo del eje reflexivo que brinda la ambigüedad de la Cultura como atolladero y trascendencia de los individuos, el presente estudio toma dos circunstancias de nuestra situación cultural (hipersubjetividad y superconductividad) como base para una reflexión en torno a las posibles deformaciones del proceso postmoderno de personalización y sobre sus correspondientes enmiendas -mediación densa (resistencia), inspiración (recogimiento) y ruptura de la inmanencia (responsabilidad)-, que puedan reorientar el desarrollo del individuo como Uno entre Otros.

Desde una perspectiva transnacional y comparada, que incorpora la experiencia del exilio, este trabajo analiza las tensiones identitarias que afectaron a la juventud militante de la izquierda revolucionaria española y argentina durante los años setenta. A través de las relaciones familiares y de género, estudia las formas públicas y privadas del compromiso y la transgresión. Aborda cómo la politización de lo privado marcó a hombres y mujeres dentro de un proceso global contestatario, heredero del 68, para destacar las contradicciones que (...) afloraron entre la teoría y la práctica, el deseo y la realidad, que llevaron a los jóvenes militantes a asumir un régimen emocional en constante debate entre el ser y el deber ser.

Since Darwin, Biology has been framed on the idea of evolution by natural selection, which has profoundly influenced the scientific and philosophical comprehension of biological phenomena and of our place in Nature. This book argues that contemporary biology should progress towards and revolve around an even more fundamental idea, that of autonomy. Biological autonomy describes living organisms as organised systems, which are able to self-produce and self-maintain as integrated entities, to establish their own goals and norms, and to promote the (...) conditions of their existence through their interactions with the environment. Topics covered in this book include organisation and biological emergence, organisms, agency, levels of autonomy, cognition, and a look at the historical dimension of autonomy. The current development of scientific investigations on autonomous organisation calls for a theoretical and philosophical analysis. This can contribute to the elaboration of an original understanding of life - including human life - on Earth, opening new perspectives and enabling fecund interactions with other existing theories and approaches. This book takes up the challenge. (shrink)

A première vue, la différence que Kant fait dans sa Critique de la raison pure entre jugements particulier et singulier semble être dénuée d’une véritable importance philosophique. D’ailleurs, dans cette même veine, l’on s’est demandé très tôt s’il fallait vraiment que les catégories soient regroupées par trois plutôt que par deux, puisque la troisième semble résulter de la connexion des deux autres, et c’est l’observation que le fidèle Johann Schultz s’enhardira à faire respectueusement au philosophe dans une lettre de 1784 (...) dont nous aurons à reparler. Entre-temps, l’on s’est habitué: le caractère tout d’abord déconcertant de l’architectonique kantienne est ce qui disparaît à l’usage, sinon à l’usure; et s’il ne perd rien de son caractère insolite aux yeux des générations d’étudiants qui se penchent avec perplexité sur ces pages sacrées, cet «art des systèmes» paraît un décor baroque que l’on finit par oublier par la force de l’habitude pour se concentrer sur ce qui ferait office d’intrigue et peut se raconter à qui n’aurait pas lu l’oeuvre.

La conception qu'Emmanuel Kant se faisait des mathematiques etait en parfaite consonance avec l'opinion philosophique la plus courante au XVIIIe siecle a l'egard de cette science. Il conviendrait par consequent de tenir davantage compte de l'histoire des idees scientifiques, ce qui permettrait de faire remarquer que la pensee kantienne releve d'un paradigme scientifique plus ancien, celui de la geometrie euclidienne (ou l'image reste intimement articulee au signe), alors que les critiques ordinairement adressees au Kant mathematicien s'appuient indirectement sur l'heritage de (...) la revolution algebrique par lequel le signe est desormais dissocie de l'image. Il convenait donc d'examiner dans le plus grand detail la maniere dont, a travers son oeuvre, Kant recevait et discutait les conceptions mathematiques de son temps, et en particulier la tension marquee entre la geometrie et l'arithmetique. Ce faisant, il redevient possible de recontextualiser le concept kantien d'intuition par rapport aux evidences de son temps, qui ne sont plus tout a fait les notres. Les reticences de Kant vis-a-vis des concepts les plus problematiques de l'algebre se laissent ainsi interpreter a nouveaux frais, faisant ressortir la signification de l'architectonique. (shrink)

Most everyday tasks involve multiple modalities, which raises the question of how the processing of these modalities is coordinated by the cognitive system. In this paper, we focus on the coordination of visual attention and linguistic processing during speaking. Previous research has shown that objects in a visual scene are fixated before they are mentioned, leading us to hypothesize that the scan pattern of a participant can be used to predict what he or she will say. We test this hypothesis (...) using a data set of cued scene descriptions of photo-realistic scenes. We demonstrate that similar scan patterns are correlated with similar sentences, within and between visual scenes; and that this correlation holds for three phases of the language production process (target identification, sentence planning, and speaking). We also present a simple algorithm that uses scan patterns to accurately predict associated sentences by utilizing similarity-based retrieval. (shrink)

When people communicate, they coordinate a wide range of linguistic and non-linguistic behaviors. This process of coordination is called alignment, and it is assumed to be fundamental to successful communication. In this paper, we question this assumption and investigate whether disalignment is a more successful strategy in some cases. More specifically, we hypothesize that alignment correlates with task success only when communication is interactive. We present results from a spot-the-difference task in which dyads of interlocutors have to decide whether they (...) are viewing the same scene or not. Interactivity was manipulated in three conditions by increasing the amount of information shared between interlocutors. We use recurrence quantification analysis to measure the alignment between the scan-patterns of the interlocutors. We found that interlocutors who could not exchange feedback aligned their gaze more, and that increased gaze alignment correlated with decreased task success in this case. When feedback was possible, in contrast, interlocutors utilized it to better organize their joint search strategy by diversifying visual attention. This is evidenced by reduced overall alignment in the minimal feedback and full dialogue conditions. However, only the dyads engaged in a full dialogue increased their gaze alignment over time to achieve successful performances. These results suggest that alignment per se does not imply communicative success, as most models of dialogue assume. Rather, the effect of alignment depends on the type of alignment, on the goals of the task, and on the presence of feedback. (shrink)

Qu'est-ce qu'un 'philosophe', au regard de l'histoire et singulièrement du XXIe siècle? Frank Pierobon, en s'appuyant sur son propre parcours et aussi sur ses dix années d'engagement dans la riche aventure des Matins-Philo à Bruxelles, tente d'apporter une réponse située à la question. Loin des imageries populaires, il fait du philosophe un homme de métier et de savoir-être dont toute l'existence oscillerait entre la création de concepts et, en même temps, une quête incessante du désir de sens. Un texte (...) court et fulgurant qui redit que nul n'est dispensé de philosopher. (shrink)

Dynamicism has provided cognitive science with important tools to understand some aspects of “how cognitive agents work” but the issue of “what makes something cognitive” has not been sufficiently addressed yet and, we argue, the former will never be complete without the latter. Behavioristic characterizations of cognitive properties are criticized in favor of an organizational approach focused on the internal dynamic relationships that constitute cognitive systems. A definition of cognition as adaptive-autonomy in the embodied and situated neurodynamic domain is provided: (...) the compensatory regulation of a web of stability dependencies between sensorimotor structures is created and preserved during a historical/developmental process. We highlight the functional role of emotional embodiment: internal bioregulatory processes coupled to the formation and adaptive regulation of neurodynamic autonomy. Finally, we discuss a “minimally cognitive behavior program” in evolutionary simulation modeling suggesting that much is to be learned from a complementary “minimally cognitive organization program”.

In this article, we propose some fundamental requirements for the appearance of adaptivity. We argue that a basic metabolic organization, taken in its minimal sense, may provide the conceptual framework for naturalizing the origin of teleology and normative functionality as it appears in living systems. However, adaptivity also requires the emergence of a regulatory subsystem, which implies a certain form of dynamic decoupling within a globally integrated, autonomous system. Thus, we analyze several forms of minimal adaptivity, including the special case (...) of motility. We go on to explain how an open-ended complexity growth of motility-based adaptive agency, namely, behavior, requires the appearance of the nervous system. Finally, we discuss some implications of these ideas for embodied robotics. (shrink)

Since Darwin it is widely accepted that natural selection (NS) is the most important mechanism to explain how biological organisms—in their amazing variety—evolve and, therefore, also how the complexity of certain natural systems can increase over time, creating ever new functions or functional structures/relationships. Nevertheless, the way in which NS is conceived within Darwinian Theory already requires an open, wide enough, functional domain where selective forces may act. And, as the present paper will try to show, this becomes even more (...) evident if one looks into the problem of origins. If there was a time when NS was not operating (as it is quite reasonable to assume), where did that initial functional diversity, necessary to trigger off the process, come from? Self-organization processes may be part of the answer, as many authors have claimed in recent years, but surely not the complete one. We will argue here that a special type of self-maintaining organization, arising from the interplay among a set of different endogenously produced constraints (pre-enzymatic catalysts and primitive compartments included), is required for the appearance of functional diversity in the first place. Starting from that point, NS can progressively lead to new (and, at times, also more complex) organizations that, in turn, provide wider functional variety to be selected for, enlarging in this way the range of action and consequences of the mechanism of NS, in a kind of mutually enhancing effect.

Our goal in this paper is to articulate a precise concept of at least a certain kind of disease-mongering, showing how pharmaceutical marketing can commercially exploit certain diseases when their best definition is given through the success of a treatment in a clinical trial. We distinguish two types of disease-mongering according to the way they exploit the definition of the trial population for marketing purposes. We argue that behind these two forms of disease-mongering there are two well-known problems in the (...) statistical methodology of clinical trials (the reference class problem and the distinction between statistical and clinical significance). Overcoming them is far from simple. (shrink)

Justifying his proposal for “health savings accounts,” which would allow individuals to set aside tax-free dollars against future healthcare needs, President Bush has said that “Health savings accounts all aim at empowering people to make decisions for themselves.” Who could disagree with such a sentiment? Although bioethicists may be among those who express skepticism that personal health savings accounts will be part of the needed “fix” of our healthcare financing system, self determination has long been part of their mantra. Indeed, (...) the field of bioethics played an important role in advancing this idea in the medical world when physician paternalism was regnant. Has its popularity caused it to become so vapid as to be ripe for misuse? (shrink)

The human sentence processor is able to make rapid predictions about upcoming linguistic input. For example, upon hearing the verb eat, anticipatory eye-movements are launched toward edible objects in a visual scene. However, the cognitive mechanisms that underlie anticipation remain to be elucidated in ecologically valid contexts. Previous research has, in fact, mainly used clip-art scenes and object arrays, raising the possibility that anticipatory eye-movements are limited to displays containing a small number of objects in a visually impoverished context. In (...) Experiment 1, we confirm that anticipation effects occur in real-world scenes and investigate the mechanisms that underlie such anticipation. In particular, we demonstrate that real-world scenes provide contextual information that anticipation can draw on: When the target object is not present in the scene, participants infer and fixate regions that are contextually appropriate. Experiment 2 investigates whether such contextual inference requires the co-presence of the scene, or whether memory representations can be utilized instead. The same real-world scenes as in Experiment 1 are presented to participants, but the scene disappears before the sentence is heard. We find that anticipation occurs even when the screen is blank, including when contextual inference is required. We conclude that anticipatory language processing is able to draw upon global scene representations to make contextual inferences. These findings are compatible with theories assuming contextual guidance, but posit a challenge for theories assuming object-based visual indices. (shrink)

La Critique de la raison pure d'Emmanuel Kant est incontestablement l'un des ouvrages-clefs de la tradition philosophique. Paradoxalement, la fascination qu'elle a durablement exercée sur des générations de philosophes est à la mesure du mystère de sa construction dont on a maintes fois constaté la rigueur et l'omniprésence, mais dont on a peu examiné, jusqu'à présent, les conditions de possibilité. Pourtant Kant ne se lasse pas de souligner la prépondérance de la systématicité, qu'il appelle " architectonique ", dans la fonction (...) critique de sa pensée. Cette architectonique est souvent assimilée à une quelconque architecture de façade et qui serait à la philosophie ce que devrait être un bon système de rangement pour une bibliothèque : rien de plus qu'une commodité instrumentale qui ne peut rien ajouter à la valeur littéraire des livres qui y sont rangés. A l'opposé de cette conception naïve et réductrice, il faut prendre conscience de ce que l'architectonique régit jusqu'au détail l'essentiel de la pensée kantienne et, loin de constituer un système de juxtaposition rhétorique, guide d'une main sûre la pensée, là où celle-ci devient aveugle. Il s'agit non seulement de la très célèbre illusion transcendantale, mais encore de ce qui ne se laisse pas représenter adéquatement : l'idée. Or le système architectonique de la raison pure dépend lui-même d'une idée et de ce fait reste principalement inexponible en une seule représentation conceptuelle. Cet ouvrage livre non seulement la structure architectonique complète sous-jacente à la Critique mais encore retrouve le schème kantien de l'architectonique qui permet de penser cette description en tant que complète, à travers le jeu d'éclipses dont la logique transcendantale fait son propos. Les lecteurs de Kant seront en particulier intéressés par la reconstitution génétique de la table des catégories en tant que système et par l'explication de cette apparence propre à la table des catégories et, par là, à l'entendement pur (c'est-à-dire la logique formelle), d'être sans fondement, sans racine, comme la connaissance absolue d'un entendement intuitif. Jetant ainsi de nouvelles lumières sur cet ouvrage méconnu à force d'être commenté, Kant et la fondation architectonique de la métaphysique en propose une lecture dont l'originalité tient à ce qu'elle prend la Critique de la raison pure au pied de la lettre et qu'ainsi elle en retrouve l'esprit authentique et en révèle la vertigineuse modernité.

This paper develops a largely neglected parallel between prudence and population ethics. Prudence is generally understood to be concerned with the balancing of well-being over time. How, precisely, well-being ought to be balanced over time, however, is a fervently debated question. I argue that developing a standard guiding such evaluations is exceedingly challenging. This is due to an often overlooked fact about prudence, namely that it shares a structural similarity with population ethics: In both contexts, we assess the comparative value (...) of populations of personstages/people, which may vary in number and level of well-being. Based on this analogy, I show that the development of an adequate theory of prudence runs into very similar impossibility results as obtain in population ethics. In particular, I prove that Arrhenius’ fifth impossibility theorem can be applied to prudence. I develop and compare four possible answers to this challenge. First, I discuss the possibility of accepting the very repugnant conclusion intrapersonally. Second, I present and further develop Donald Bruckner’s Minimax Regret approach, which gives up Transitivity. Third, I apply Jacob Nebel’s Lexical Threshold View to prudence and critically evaluate it. Lastly, I introduce what I call the Negative Lexicality View, which is based on Lexical Threshold View but overcomes some of its problems. (shrink)
