In an undated letter, Peirce claims that he can make a machine that will automatically encrypt and decrypt messages, an astonishing claim considering the state of American science during his time. In two undated manuscripts, Peirce actually describes a cryptosystem, a system for encrypting and decrypting, suggesting the use of arithmetical transformations and binary notation. The relationship between the manuscripts and the letter are discussed in the paper. The paper also describes Peirce’s cryptosystem, places it in its historical context and (...) assesses its comparative value. The paper ends with speculations on whether Peirce could really have built the machine. Considering that he understood the relationship between electricity, binary arithmetic, and Boolean logic, and was familiar with the experiences on the logical machines of his time, the paper concludes that Peirce had all the knowledge necessary to build such a machine.

The shift in Foucault’s work from genealogy to ethics finds consensus among Foucault scholars. However, the motivations behind this transition remain either misunderstood or understudied in large part. Foucault’s recently published or soon-to-be translated 1977/—9 lectures (published as Security, Territory, Population and as The Birth of Biopolitics) offer new elements for understanding this dense and uncharted period along Foucault’s itinerary. In this article, the author argues that Foucault’s interpretation of the liberal tradition, which is at the core of the 1977—9 (...) lectures, must be examined in combination with Foucault’s other major interests in the late 1970s, namely the Iranian Revolution and Kant. The discovery of spirituality (Iran), the valorization of an autonomous subject (Kant) and the call for a tolerant environment towards minority practices (liberalism) pave the way for the later Foucault’s ethics, which are grounded in spiritual exercises and means of liberating the subject.

Walter Sinnott-Armstrong has recently criticized moral intuitionism by bringing to light some compelling empirical evidence indicating that we are unreliable at forming moral judgments non-inferentially. The evidence shows that our non-inferentially arrived-at moral convictions are subject to framing effects; that is, they vary depending on how the situation judged is described. Thomas Nadelhoffer and Adam Feltz, following in Sinnott-Armstrong's footsteps, have appealed to research indicating that such judgments are also subject to actor-observer bias; that is, they vary depending on whether (...) the situation judged includes the judger as an actor in, or an observer of, the situation. The accuracy of this empirical evidence will not be challenged in what follows. What will be called into question is its purported relevance for moral intuitionism. To that end we will consider a version of moral intuitionism developed by Iris Murdoch that not only accommodates but essentially relies on the existence of various kinds of distorting factors including framing effects and actor-observer bias.

This paper aims to contribute to current discussions about methods in anthropological (especially ethnographic) research on the cultures of the internet. It does so by considering how technology has been presented in turn as an epistemological boon and bane in methodological discourse around virtual or online ethnography, and cyberanthropology. It maps these discussions with regards to intellectual traditions and ambitions of ethnographic research and social science, and considers how these views of technology relate to modernist discourse about the value of (...) technology for producing a particular kind of objective knowledge. For this article, I have examined a number of monographs and methodological texts in which the internet, as both a new setting and a new technology for doing ethnography, is shown to raise new issues for ethnographic work and for theorising anthropological approaches. In this material, questions of presence, field relations (including trust and confidentiality), and new possibilities for observation are especially prominently discussed. Anxieties about whether the internet can be a field at all are also expressed. In my analysis, I place these issues and dilemmas facing the researcher in the context of the intellectual tradition of ethnography as applied to technology. The main themes found to subtend these discussions of ethnography's 'way of knowing' are the notion of 'field', technology, intersubjectivity and capture. The paper ends with a reflection on the kind of knowledge about the internet that ethnography can be expected to produce, given these methodological prescriptions. (shrink)
Depuis le milieu des annees 1960, les etudes spinozistes ont pris un nouvel essor sous l'impulsion du courant marxiste qui a vu dans le programme de liberation des collectivites pense par Spinoza le projet politique le plus apte ä assurer une reponse ä la crise de legitimite du marxisme. Dans la foulee de certaines intuitions de Althusser, et ä la lumiere de la conceptualite spinoziste, plusieurs penseurs (notamment Deleuze, Negri, Macherey, Matheron et Virno) ont ainsi propose un nouveau modele d'organisation (...) de la vie en commun. Ces acteurs de la renaissance spinoziste redigent, en quelque sorte, le chapitre conclusif de la derniere ceuvre de Spinoza (i.e. le Tratte politique reste inacheve) en definissant les nouvelles conditions de la democratic ä l'heure de la deterritorialisation generalisee marquee par l'abolition des frontieres nationales (economie mondiale, reseaux informatiques, etc.). Ce contexte offre l'occasion de repenser la politique en radicalisant les propos de Spinoza et en faisant jouer les notions de "puissance" et de "multitude" non seulement contre les concepts de "pouvoir" et de "peuple" qui en sont venus ä dominer le champ de la reflexion en philosophic politique, mais egalement contre les philosophies de l'histoire fondees sur la dialectique et la teleologie. Apres avoir decrit brievement quelques-uns des principaux enjeux de la politique spinoziste et avoir presente les nouveaux ennemis du spinozisme (neo-liberalisme et marxisme ideologique), nous ferons une genealogie de la refondation neo-spinozienne de Marx (Althusser, Deleuze, Negri) avant de repondre ä la question "Que faire?". II s'agira alors de determiner le role de l'Etat et de situer cette pensee politique par rapport ä l'utopie revolutionnaire. Ce parcours contribuera ä mieux definir les fondements et les implications de la democratic non-representative qui est au cceur des revendications de la renaissance spinoziste. (shrink)
Derrida’s intellectual itinerary shows a progressive reconciliation with Lévinas’ ethical thinking. “Violence and Metaphysics”, one of Derrida’s earlier essays, was highly critical of Lévinas’ “phallotheology”, whereas his later works were more receptive to the Levinasian analysis on hospitality, “cities of refuge” (villes-refuges) and justice. This essay will discuss the mutual terminological exchanges between Derrida and Lévinas as well as some divergences between the two thinkersregarding the deconstruction project. Finally, we will see how Derrida distinguishes himself from Lévinas’ ethics by bringing (...) an end to the search for the conditions of possibility of experience in favour of a more radical experience of the impossible and the inconditional.

The Influence of turbulence on nutrient fluxes towards phytoplankton cells has been previously estimated, but those studies did not take into account the intermittent nature of turbulent processes. This has been investigated here comparing the nutrient fluxes obtained using both mean and instantaneous turbulent energy dissipation rates. This approach shows that the size of cell potentially influenced by turbulence is lower than previously indicated, and that the spectral average estimate of the turbulence effect overestimates the flux. The capacity of cell (...) to use such intermittent flux is then discussed. (shrink)
A study of stage structured model of fish population is presented. This model focuse on the anchovy population in the Bay of Biscay (Engraulis encrasicolus L.) is presented. The method of study is based on an intermediate complexity mathematical model, taking into account the spatialisation, the environmental conditions and the stage-structure of the fishes. First, to test the model, we show mathematical properties, such as unicity of the solution of structural stability. Then we provide numerical simulations, to validate the model (...) and to test the dynamics according to the variations of the parameters. (shrink)
Social grooming is an important element of social life in terrestrial primates, inducing the putative benefits of β-endorphin stimulation and group harmony and cohesion. Implicit in many analyses of grooming (e.g. biological markets) are the assumptions of costs and benefits to grooming behaviour. Here, in a review of literature, we investigate the proximate costs and benefits of grooming, as a potentially useful explanatory substrate to the well-documented ultimate (functional) explanations. We find that the hedonic benefits of grooming are well documented. (...) However, we did not find convincing evidence for costs. If proximate costs do exist, they might consist of energetic, cognitive, opportunity costs, or some combination of all of these. Nonetheless, there remains the possibility that grooming costs are negligible, or even that the provision of allogrooming is rewarding in itself. We suggest empirical research to resolve this issue.
