In topological spaces, the relation of extended contact is a ternary relation that holds between regular closed subsets A, B and D if the intersection of A and B is included in D. The algebraic counterpart of this mereotopological relation is the notion of extended contact algebra which is a Boolean algebra extended with a ternary relation. In this paper, we are interested in the relational representation theory for extended contact algebras. In this respect, we study the correspondences between point-free (...) and point-based models of space in terms of extended contact. More precisely, we prove new representation theorems for extended contact algebras. (shrink)

The seemingly "inextricable" mutual entanglement of history and the play of power dissolves itself when thinking, under the sway of technique, moves beyond the horizon of metaphysic, and turns to question the unconcealment of being, that is, when man lets time become the law of his essence. Only so would a history, i.e. freedom, happen again, and rescue modern man from his otherwise destinyless age.

This paper argues that besides mechanistic explanations, there is a kind of explanation that relies upon “topological” properties of systems in order to derive the explanandum as a consequence, and which does not consider mechanisms or causal processes. I first investigate topological explanations in the case of ecological research on the stability of ecosystems. Then I contrast them with mechanistic explanations, thereby distinguishing the kind of realization they involve from the realization relations entailed by mechanistic explanations, and explain how both (...) kinds of explanations may be articulated in practice. The second section, expanding on the case of ecological stability, considers the phenomenon of robustness at all levels of the biological hierarchy in order to show that topological explanations are indeed pervasive there. Reasons are suggested for this, in which “neutral network” explanations are singled out as a form of topological explanation that spans across many levels. Finally, I appeal to the distinction of explanatory regimes to cast light on a controversy in philosophy of biology, the issue of contingence in evolution, which is shown to essentially involve issues about realization.

Animal research suggests that central serotonergic neurons are involved in behavioral suppression, particularly anxiety-related inhibition. The hypothesis linking decreased serotonin transmission to reduced anxiety as the mechanism in the anxiolytic activity of benzodiazepines conflicts with most clinical observations. Serotonin antagonists show no marked capacity to alleviate anxiety. On the other hand, clinical signs of reduced serotonergic transmission (low 5-HIAA levels in the cerebrospinal fluid) are frequently associated with aggressiveness, suicide attempts, and increased anxiety. The target article attempts to reconcile such (...) human and animal findings by investigating whether anxiety reduction or increased impulsivity is more Likely to account for animal behavioral changes associated with decreased serotonergic transmission. The effects of manipulating central serotonin in experimental anxiety paradigms in animals (punishment, extinction, novelty) are reviewed and compared with the effects of antianxiety drugs. Anxiety seems neither necessary nor sufficient to induce control by serotonergic neurons on behavior. Further evidence suggests that behavioral effects of anxiolytics thought to be mediated by decreases in anxiety are not caused by the ability of these drugs to reduce serotonin transmission. Blockade of serotonin transmission, especially at the level of the substantia nigra, results in a shift of behavior toward facilitation of responding. This behavioral shift is particularly marked when there is competition between acting and restraining response tendencies and when obstacles prevent the immediate attainment of an anticipated reward. It is proposed that serotonergic neurons are involved not only in behavioral arousal but also in enabling the organism to arrange or tolerate delay before acting. Decreases in serotonin transmission seem to be associated with the increased performance of behaviors that are usually suppressed, though not necessarily because of the alleviation of anxiety, which might contribute to the suppression.

Des premiers rites baptismaux à la confession moderne, les références au christianisme sont constantes dans l'œuvre de Michel Foucault. Cette constance s'inscrit dans un questionnement philosophique plus large sur notre actualité : comprendre le rapport que nous avons aujourd'hui à nous-mêmes demande de s'interroger sur les actes de vérité que l'Occident a instaurés depuis les premiers siècles chrétiens. Que faut-il dire et manifester de soi pour être transformé dans son être, pardonné, sauvé, jugé ou guéri)? Ce livre propose une étude (...) critique de l'ensemble des lectures chrétiennes de Foucault, avec une attention particulière portée au cours Du gouvernement des vivants. Ni chronologique ni thématique, le parcours suivi espère retrouver la logique d'un travail à la fois philosophique et historique : quand et comment le christianisme a-t-il été constitué par Foucault en objet de recherche, avec quelles pratiques de lecture et quelles conséquences sur l'interprétation)?

Besides mechanistic explanations of phenomena, which have been seriously investigated in the last decade, biology and ecology also include explanations that pinpoint specific mathematical properties as explanatory of the explanandum under focus. Among these structural explanations, one finds topological explanations, and recent science pervasively relies on them. This reliance is especially due to the necessity to model large sets of data with no practical possibility to track the proper activities of all the numerous entities. The paper first defines topological explanations (...) and then explains why topological explanations and mechanisms are different in principle. Then it shows that they are pervasive both in the study of networks—whose importance has been increasingly acknowledged at each level of the biological hierarchy—and in contexts where the notion of selective neutrality is crucial; this allows me to capture the difference between mechanisms and topological explanations in terms of practical modelling practices. The rest of the paper investigates how in practice mechanisms and topologies are combined. They may be articulated in theoretical structures and explanatory strategies, first through a relation of constraint, second in interlevel theories, or they may condition each other. Finally, I explore how a particular model can integrate mechanistic informations, by focusing on the recent practice of merging networks in ecology and its consequences upon multiscale modelling.

As part of a recent attempt to extend the methods of formal semantics beyond language, it has been claimed that music has an abstract truth-conditional semantics, albeit one that has more in common with iconic semantics than with standard compositional semantics. After summarizing this approach and addressing a common objection, we argue that music semantics should be enriched in three directions by incorporating insights of other areas of Super Semantics. First, it has been claimed by Abusch 2013 that visual narratives (...) make use of discourse referents akin to those we find in language. We argue that a similar conclusion extends to music, and we highlight it by investigating ways in which orchestration and dance may make cross-referential dependencies more explicit. Second, we show that by bringing music semantics closer to the semantics of visual narratives, we can give an account of the semantics of mixed visual and musical sequences. Third, it has been claimed that co-speech gestures trigger characteristic conditionalized presuppositions, called ‘cosuppositions’, and that their semantic status derives from their parasitic character relative to words. We argue that the same conclusion extends to some instances of film and cartoon music: it may trigger cosuppositions that can be revealed by embedding film excerpts or gifs in sentences so as to test presupposition projection. We further argue that under special discourse conditions, pro-speech gestures and pro-speech music alike can trigger cosuppositions as well. These results suggest that new insights can be gained not just by extending the methods of semantics to new objects, but also by drawing new connections among them. (shrink)

Several disputes about the nature of experience operate under the assumption that experiences have parts, including temporal parts. There's the widely held view, when it comes to temporal experiences, that we should follow James' exhortation that such experiences aren't mere successions of their temporal parts, but something more. And there's the question of whether it is the parts of experiences which determine whole experiences and the properties they have, or whether the determination goes instead from the whole to the parts, (...) as holists have it. But what are parts, or temporal parts, of experiences exactly—what does it mean to say that an experience is “part” of another? Are the participants in those disputes talking about the same thing—is there a univocal notion of “experiential part” available? Are there different kinds of experiential parts? And if there are, is there a systematic way of carving them out? More importantly, how should we conceive of the temporal parts of experiences, and how can we establish that experiences really do have temporal parts, against those who reject the notion? (shrink)

Kant’s analysis of the concept of natural purpose in the Critique of judgment captured several features of organisms that he argued warranted making them the objects of a special field of study, in need of a special regulative teleological principle. By showing that organisms have to be conceived as self-organizing wholes, epigenetically built according to the idea of a whole that we must presuppose, Kant accounted for three features of organisms conflated in the biological sciences of the period: adaptation, functionality (...) and conservation of forms..Kant’s unitary concept of natural purpose was subsequently split in two directions: first by Cuvier’s comparative anatomy, that would draw on the idea of adaptative functions as a regulative principle for understanding in reconstituting and classifying organisms; and then by Goethe’s and Geoffroy’s morphology, a science of the general transformations of living forms. However, such general transformations in nature, objects of an alleged ‘archaeology of nature’, were thought impossible by Kant in the §80 of the Critique of judgment. Goethe made this ‘adventure of reason’ possible by changing the sense of ‘explanation’: scientific explanation was shifted from the investigation of the mechanical processes of generation of individual organisms to the unveiling of some ideal transformations of types instantiated by those organisms.

When engaging with classical Chinese ethics, we might end up wondering what kind of moral theorizing we ultimately are confronted with. The accounts and answers to specific practical problems are dispersed throughout the texts and expressed via various codes of composition, ranging from sayings to theoretical reflections to poems. However, what exactly the aim of these theories consists in is not explicitly addressed by systematic second-order reflections. In this article I try to shed some light on the understanding of moral (...) theorizing that underlies the transmitted texts. For this, I adopt an issue-centered approach that attempts to indirectly address the understanding of moral theorizing via the question about the source of normativity. That approach will be tested by drawing on the accounts of Mengzi 孟子 and Cheng Yi 程頤. First conclusions will show that moral theorizing can be understood as the simultaneous business of a moral anatomist and a moral painter. (shrink)

Il n'y a pas de beauté sans «contraires unis», c'est-à-dire sans coexistence à l'intérieur d'une même oeuvre de tendances antithétiques pour l'intellect, mais fondues d'une manière intime. La Beauté éclate quand ce qui est intellectuellement séparé ne forme plus qu'une unité profondément éprouvée. Ainsi les oeuvres les plus belles sont celles où s'interpénètrent un grand nombre de tendances, comme si les divergences s'effaçaient lorsqu'on s'achemine vers le plus profond.

Les discours sur la fin de l'histoire, dominants à la fin du siècle dernier, ont laissé place aux discours marquants la fin de la géographie, à l'urgence climatique et à l'effondrement. Ces considérations s'enracient dans l'histoire de la philosophie, chez Montesquieu en particulier. La mondialisation et les multiples crises (économique, sociale, politique et sanitaire) que nous traversons, nous imposent un nouveau questionnement pour nous resituer historiquement et géographiquement ; ces deux dimensions étant, de plus, inséparables. La géographie conceptualisant l'espace rend (...) intelligible la temporalité historique. Peut-on pour autant entériner la fin de l'histoire ou de la géographie, la contraction d'un monde englouti par les nouvellles technologies et les moyens de communication instantanés? (shrink)

Wat dacht Nietzsche, die niet bepaald positief stond ten opzichte van het christendom, eigenlijk over Jezus? Er wordt immers wel beweerd dat je, wat je verder ook van het christendom denkt, onmogelijk tegen Jezus kunt zijn. In zijn vroege werk noemt Nietzsche hem inderdaad 'de edelste mens'. Maar later heeft hij het over 'een grote egoïst' en in 'Der Antichrist' zegt hij zelfs dat Jezus 'een idioot' was. Wat betekent dat allemaal precies binnen het denken van een filosoof die vaak (...) niet rechtstreeks zegt wat hij eigenlijk bedoelt? Kunnen deze gedachten voor ons vandaag nog iets betekenen? Lepers heeft het volledige oeuvre van Nietzsche onderzocht op uitspraken en beschouwingen over en rond de figuur van Jezus. Dat voert hem tot genuanceerde, soms (schijnbaar?) tegenstrijdige, maar altijd uitdagende antwoorden op de vraag wie en wat Jezus in Nietzsches ogen was en wat hij vanuit dat perspectief voor ons zou kunnen zijn.

This article discusses how Liang Shuming’s Eastern and Western Cultures and Their Philosophies adopted a genealogical mode of textual authorization which took shape in its depiction of Chinese history as a failure to live up to an ideal way of life imagined by Confucius. Implied in this discourse was the idea that Liang himself had been the first Confucian to understand what Confucius had truly meant. This genealogical discourse authorizing Liang and his text by linking them directly to Confucius was (...) further strengthened by a rhetoric which naturalized the discourse passed down from Confucius to Liang, distinguishing it from other forms of discourse seen as artificial. Finally, the text’s genealogical discourse also managed to incorporate the May Fourth critique of Confucianism by rejecting the historical manifestations of Confucianism before salvaging an ideal imagined by Confucius which was presented as uncontaminated by history and Confucianism’s enmeshment with state power.

Based on the analysis of narrations in Free Indirect Discourse and the Historical Present, we argue that the grammatical notion of context of speech should be ramified into a Context of Thought and a Context of Utterance. Tense and person depend on the Context of Utterance, while all other indexicals are evaluated with respect to the Context of Thought. Free Indirect Discourse and the Historical Present are analyzed as special combinatorial possibilities that arise when the two contexts are distinct, and (...) exactly one of them is presented as identical to the physical point at which the sentence is articulated.
