Posthumanism’s abandonment of language and embrace of natural sciences can impede thinking about “selfhood, embodiment, mate-riality.” The role of language in a posthuman context involves a tri-ple consideration: ethics, history, and enunciation. The ethical di-mension works through the biopolitical risk of determinism. Any ethical “situatedness” must account for history. Finally, working through Agamben’s thought via Benvenistian linguistics (which in-fluence Agamben), I examine the interplay of ethics and history with respect to enunciation as an alternative to the legacy of de-construction. The (...) claim here is that the gaps between embodiment and materiality, and the singularities of experience and ethics, in-volve history and language as “pure means.”. (shrink)

La science étudie un système en évaluant ses grandeurs caractéristiques: elle définit ses dimensions. Combien de dimensions caractérisent le réel? Quelles dimensions sont les plus pertinentes? La physique classique étudie trois dimensions de l'espace et une de temps. Ces quatre dimensions sont réunies par la relativité restreinte et générale. Les théories cosmologiques les plus modernes en font intervenir de nouvelles, presque imperceptibles à l'homme. En mathématiques, le nombre de dimensions caractérisant un système peut être non entier. En biologie, on peut (...) s'interroger sur la dimension du système fondamental à étudier: la cellule, l'organe, l'individu? Comment la taille d'un organisme influe-t-elle sur son appréhension du réel? Enfin, en art pictural, comment représente-t-on les formes, la profondeur? De nouvelles questions fondamentales, une nouvelle approche pluridisciplinaire vous sont ici proposées. (shrink)

Research on elders’ acceptance of virtual technologies is much needed. Here we studied the user experience of elders (N = 10, mean age = 88.2 years) during virtual biking, an exergame where participants pedal on a cycle ergometer and wear a Head-Mounted Display that provides them an immersive experience of a bike ride. We tested the effects of augmented gaze on user experience. Augmented gaze is a condition in which horizontal head turns yield amplified visual shifts, which is assumed to (...) facilitate visual exploration. User experience was measured by asking participants to rate satisfaction, motivation, sense of presence and sense of safety. We found a very good acceptance of virtual biking and no signs of negative effects of augmented gaze. These preliminary observations suggest that augmented gaze may be a viable optimization of elders’ experience with certain virtual reality applications. (shrink)

L'axe principal de ce texte du philosophe polonais Emil Lask (1875-1915) est la critique de la philosophie de la valeur et la théorie de la connaissance. Son exposé est l'une des révisions du kantisme les plus radicales du début du XXe siècle.

The book contains critical analyses of injustice in connection to law and ethics, and develops normative alternatives linked to justice. It covers the relevant issues from social justice to cyber justice. The chapters address issues and concepts which guideline on social innovations, transformations inherent in democratizing processes, global conflicts and other interactions, including the ultimate danger of escalation to war conflicts, be they conventional wars or new cyberwars.--From publisher's website.
