Cultural evolution studies are characterized by the notion that culture evolves accordingly to broadly Darwinian principles. Yet how far the analogy between cultural and genetic evolution should be pushed is open to debate. Here, we examine a recent disagreement that concerns the extent to which cultural transmission should be considered a preservative mechanism allowing selection among different variants, or a transformative process in which individuals recreate variants each time they are transmitted. The latter is associated with the notion of “cultural (...) attraction”. This issue has generated much misunderstanding and confusion. We first clarify the respective positions, noting that there is in fact no substantive incompatibility between cultural attraction and standard cultural evolution approaches, beyond a difference in focus. Whether cultural transmission should be considered a preservative or reconstructive process is ultimately an empirical question, and we examine how both preservative and reconstructive cultural transmission has been studied in recent experimental research in cultural evolution. Finally, we discuss how the relative importance of preservative and reconstructive processes may depend on the granularity of analysis and the domain being studied. (shrink)

The first half of this article follows Mario Bunge’s early realist moves, his efforts to articulate the achievements of theoretical physics as gains in the quest for objective truth and understanding, particularly in the context of the fights against the idealist and subjectivist interpretations of quantum mechanics that, at least until the mid-1970s, prevailed in physics. Bunge’s answers to the problems of quantum mechanics provide a good angle for understanding how his realist positions grew on the “battlefield.” The second half (...) discusses Bunge’s general conception of the scientific realist stance and confronts it with some current approaches to realism in the mainstream literature.

The aim of this chapter is to analyse the concept of love —understood in the broad and Christian-inspired sense of love as agape-charis love— in relation to the animes Dragon Ball and Dragon Ball Z. I first comment on the character of Piccolo —and how his friendship with Son Gohan— leads to him losing all his original villainous traits. I argue that the evolution of the character of Piccolo through his friendship with Son Gohan illustrates the philosophical claim that a (...) loving and giving of oneself to the other —far from being a sign of weakness— is a courageous and self-affirming exercise. The result may move the individual to an inner transformative experience that leads to the enjoyment of a renewed and authentic life that is worth living. I then argue that Son Goku’s respectful attitude towards his opponents is ultimately a loving attitude. Last, I argue that it is the inspiring and loving example of Son Goku that ultimately explains why characters such as Vegeta —who are at first presented as villains— end up losing their villainous traits after fighting against Son Goku.

In Ockhamist branching-time logic [Prior 67], formulas are meant to be evaluated on a specified branch, or history, passing through the moment at hand. The linguistic counterpart of the manifoldness of future is a possibility operator which is read as `at some branch, or history (passing through the moment at hand)'. Both the bundled-trees semantics [Burgess 79] and the $\langle moment, history\rangle$ semantics [Thomason 84] for the possibility operator involve a quantification over sets of moments. The Ockhamist frames are (3-modal) (...) Kripke structures in which this second-order quantification is represented by a first-order quantification. The aim of the present paper is to investigate the notions of modal definability, validity, and axiomatizability concerning 3-modal frames which can be viewed as generalizations of Ockhamist frames.

Wikipedia est devenue en quelques années un outil de diffusion d'informations scientifiques de premier plan, utilisé par élèves, professeurs et chercheurs (parmi ces derniers, un sur dix reconnaît y contribuer). Malgré un système d'édition relativement complexe, le ' wiki de la connaissance ' a gagné en popularité (15 millions d'articles, 270 langues, 100 000 contributeurs bénévoles). On en sait davantage sur son fonctionnement : son taux d'erreur factuel est relativement similaire à celui de l'encyclopédie payante Britannica ; les articles sont (...) souvent rédigés par un petit nombre de contributeurs (5 % des contributeurs sont à l'origine de 90 % du contenu) ; une série d'' administrateurs ' jouent les pompiers ou les gendarmes, non sans s'attirer les foudres d'une partie des contributeurs ; dynamique communautaire et positionnement identitaire sont les deux motivations principales pour contribuer ; les sources scientifiques sont d'autant plus citées dans Wikipedia qu'elles le sont déjà dans le monde scientifique (le ' facteur d'impact ' est involontairement reproduit)... Comparée à ses concurrents, Citizendium et Knol, l'encyclopédie contributive se démarque par son développement insolent, mais l'éventualité d'une stabilisation du nombre d'articles (on assiste aujourd'hui à une sorte de plafonnement) laisse imaginer qu'à l'avenir les contributeurs se concentreront davantage sur la qualité des articles.

A completeness theorem is established for logics with congruence endowed with general semantics (in the style of general frames). As a corollary, completeness is shown to be preserved by fibring logics with congruence provided that congruence is retained in the resulting logic. The class of logics with equivalence is shown to be closed under fibring and to be included in the class of logics with congruence. Thus, completeness is shown to be preserved by fibring logics with equivalence and general semantics. (...) An example is provided showing that completeness is not always preserved by fibring ligics endowed with standard (non general) semantics. A categorial characterization of fibring is provided using coproducts and cocartesian liftings. (shrink)

This major publication is a history of the semantic tradition in philosophy from the early nineteenth century through its incarnation in the work of the Vienna Circle, the group of logical positivists that emerged in the years 1925-1935 in Vienna who were characterised by a strong commitment to empiricism, a high regard for science, and a conviction that modern logic is the primary tool of analytic philosophy. In the first part of the book, Alberto Coffa traces the roots of (...) logical positivism in a semantic tradition that arose in opposition to Kant's theory that a priori knowledge is based on pure intuition and the constitutive powers of the mind. In Part II, Coffa chronicles the development of this tradition by members and associates of the Vienna Circle. Much of Coffa's analysis draws on the unpublished notes and correspondence of many philosophers. The book, however, is not merely a history of the semantic tradition from Kant 'to the Vienna Station'. Coffa also critically reassesses the role of semantic notions in understanding the ground of a priori knowledge and its relation to empirical knowledge and questions the turn the tradition has taken since Vienna.

Depuis une dizaine d'années, des centaines des millions d'internautes ont donné naissance à des édifices informationnels novateurs. Ces dispositifs dits Web 2.0 constituent de nouveaux modèles éditoriaux. Ces changements,qui s'inscrivent dans la continuité de l'histoire des techniques et des usages, accélèrent considérablement les processus historiques en cours. Par la métaphore des frontières, cet article analyse les profondes mutations intervenues dans le domaine des savoirs : question de l'accès, enjeux de la mémoire collective, transformation de la nature des savoirs.

This article examines word-based puzzles as texts. In particular, it analyzes the potential of using a seemingly harmless pastime — the solving of puzzles — for propagandistic ends. Propaganda is an attempt to manipulate and dominate discourses some of whose manifestations are texts. Because a thorough examination of puzzles has not yet been undertaken, word-based puzzles will be considered first in general, followed by a detailed examination of the potential propagandistic impact of puzzles drawn from the official Nazi newspaper, Völkischer (...) Beobachter [Folkish Observer]. (shrink)

People’s awareness of tactile stimuli has been investigated in far less detail than their awareness of stimuli in other sensory modalities. In an attempt to fill this gap, we provide an overview of studies that are pertinent to the topic of tactile consciousness. We discuss the results of research that has investigated phenomena such as “change blindness”, phantom limb sensations, and numerosity judgments in tactile perception, together with the results obtained from the study of patients affected by deficits that can (...) adversely affect tactile perception such as neglect, extinction, and numbsense. The similarities as well as some of the important differences that have emerged when visual and tactile conscious information processing have been compared using similar experimental procedures are highlighted. We suggest that conscious information processing in the tactile modality cannot be separated completely from the more general processing of spatial information in the brain. Finally, the importance of considering tactile consciousness within the larger framework of multisensory information processing is also discussed. (shrink)

The aim of this chapter is to analyze the movie Fight Club, directed by David Fincher, written by Jim Uhls, and first released in the fall of 1999. The movie is based on the homonym novel by Chuck Palahniuk, published in 1996. I will argue that Fight Club is to be understood in primarily existentialist, nonethical, and nonevidential terms, showing the struggle felt by each and every one of us to find a convincing answer to the question of what (if (...) anything) counts as an authentic life that is worth living. Moreover, I will argue that the movie does not merely illustrate the struggle and the existential angst it engenders; it also advances, if not strictly speaking a theoretical answer grounded in an indisputable philosophical reasoning, then at least a practical way to face it. It is only after positively endorsing the claim that absolutely nothing (whatever it may be) externally imposed on a person can give their life ultimate meaning that a person is free to engage in a conscious, laborious, and exhausting attempt at self-affirmation, a full and positive endorsement of one’s own authenticity.
