A recent evolution of computer simulations has led to the emergence of complex computer simulations. In particular, the need to formalize composite objects (those objects that are composed of other objects) has led to what the author suggests calling pluriformalizations, i.e. formalizations that are based on distinct sub-models which are expressed in a variety of heterogeneous symbolic languages. With the help of four case-studies, he shows that such pluriformalizations enable to formalize distinctly but simultaneously either different aspects or different parts (...) or different scales of the same object or system. From an epistemological standpoint, he suggests that this kind of computer-aided complex formalization of composite objects renew the traditional relations between computer simulations, theoretical models and operational models.

The debate on whether and why misinformation is bad primarily focuses on the spread of false beliefs as its main harm. From the assumption that misinformation primarily causes harm through the spread of false beliefs as a starting point, it has been contended that the problem of misinformation has been exaggerated. Its tendency to generate false beliefs appears to be limited. However, the near-exclusive focus on whether or not misinformation dupes people with false beliefs neglects other epistemic harms associated with (...) it. Specifically, I show that misinformation also causes trouble for the epistemic goods of truth attainment, intellectual autonomy and debate pluriformity. Moreover, for each of these goods, I argue that emphasizing error-avoidance exacerbates, rather than mitigates, the harms caused by misinformation. These oversights and dilemmas show that prioritizing error-avoidance in the fight against misinformation is not a neutral default policy or necessarily a net positive. A shift in focus away from the spread of false beliefs as the main harm of misinformation is needed to better understand and counter its negative effects. (shrink)

La communication research ha oramai guadagnato una propria autonomia scientifica e accademica, sostenuta dal riconoscimento della qualità e rilevanza sociale e culturale dell’oggetto di studio. Le comunicazioni di massa sono una realtà affluente della nuova era antropologica, che si manifesta in molteplici aspetti che incidono sulla riproduzione simbolica e materiale dei sistemi sociali. Di fronte all’emergenza di un fenomeno pervasivo e pluriforme, da circa un secolo, gli studiosi si pongono il problema di come darne conto in maniera adeguata. Il libro (...) ricostruisce lo sviluppo dei differenti paradigmi che si sono affermati nel corso del Novecento, orientando i modelli teorici e le attività di ricerca sui media. -/- INDICE 11 - Prefazione.

Niettegenstaande de tendens van het failliet van het multiculturalisme is multiculturele dialoog niet weg te denken in een zich globaliserende wereld. Taylor, Gadamer, Honneth en Kymlicka hebben een bijdrage geleverd op het vlak van de erkenning van identiteit, respect en waardering van verschil. Wij voeren het argument aan dat bovenstaande auteurs niet ontsnappen aan het postmodernistisch dilemma van zelfautonomie en slachtofferschap. Dit komt doordat zij in hun rationale vertrekken van het afzonderlijke subject en deze situeren in een ruimte-tijd waarin de (...) tijd slechts een historische rol heeft en de ruimte geen actieve rol speelt. Tegenover deze uitvloeisels van het postmodern denken stellen wij het eco-communau-tarisme. Vanuit de vaststelling dat het individu denkt, spreek en handelt in de context van zijn taal en cultuur en dus vanuit zijn gemeenschap, situeren wij dit subject en de gemeenschap tevens in een particulier territorium of het ecotoop. Door middel van Hacking’s sociaal constructivisme, het Leibniziaanse meerwereldenbeeld en het biologische paradigma als nieuw denkkader, structureren wij de gemeenschap volgens een cyclisch en een lineair tijdverloop. Het cyclische waarborgt de traditie van een gemeenschap, het lineaire doet de gemeenschap evolueren naar een moreel betere toekomst en heeft een transcendent statuut. Het eco-communautarisme biedt het kader voor een kwalitatieve evolutie van individuen en gemeenschappen. Het normerend aspect hiervan is de pluriforme en multiculturele dialoog. (shrink)
