A philosophical exchange broadly inspired by the characters of Berkeley’s Three Dialogues. Hylas is the realist philosopher: the view he stands up for reflects a robust metaphysic that is reassuringly close to common sense, grounded on the twofold persuasion that the world comes structured into entities of various kinds and at various levels and that it is the task of philosophy, if not of science generally, to “bring to light” that structure. Philonous, by contrast, is the anti-realist philosopher (though not (...) necessarily an idealist): his metaphysic is stark, arid, dishearteningly bone-dry, and stems from the conviction that a great deal of the structure that we are used to attribute to the world out there lies, on closer inspection, in our head, in our “organizing practices”, in the complex system of concepts and categories that unrerlie our representation of experience and our need to represent it that way.

This is a sequel to our dialogue "Che cosa c'è e che cos'è (2003), focusing on the interplay between what there is and what there could be—between actuality and possibility—from the perspective of Hylas (here: the realist philosopher) and from the perspective of Philonous (here: the conventionalist anti-realist).

David Eso and Kay Burns edition of philosopher Leo Ferraris previously unpublished 1973 manuscript brings to light a long forgotten satirical work, which, in an age of fake news, possesses renewed relevance. The editors contextualize The Earth is Flat! for the reader with a scholarly introduction and a humorous Forewarning. Author, Leo Ferrari, draws on his extensive knowledge of classical thought and its key figures to present a history of ideas that is sometimes accurate, sometimes speculative. Speculative or alternative (...) aspects of this history support his Flat Earth theme, as do a number of scientific experiments outlined, which the reader is encouraged to try. He traces the conflict between Globularist and Planoterrestrial beliefs from antiquity to his contemporary moment of the early 1970s, marked by space exploration. Later chapters chart the activities and philosophies of the Flat Earth Society of Canada, including Ferraris experience on the lecture circuit and in media platforms. The authors method is to blur the line between seriousness and humour and to show that intellectual work can also be good fun. He uses the idea of a spinning, spherical planet to symbolically represent the alienating effects of technological modernity. (shrink)

Problem: Visions of technology, future scenarios, guiding visions represent imaginations of future states of affairs that play a functional role in processes of technological research, development and innovation—e.g. as a means to create attention, communication, coordination, or for the strategic exertion of influence. Since a couple of years there is a growing attention for such imaginations of futures in politics, the economy, research and the civil society. This trend concerns technology assessment as an observer of these processes and a consultant (...) on the implications of technology and innovation. TA faces increasing demands to assess imaginations of futures that circulate in the present and to participate in shaping these through scenarios or foresights. More than ever, this raises the question, which propositions can be made based on these imaginations by TA and how this can be used in advisory practices. Imaginations of futures are relevant for TA not as predictions but in their significance and effectiveness in the present, which need to be understood and assessed.Contents: This discussion paper outlines how present significance and effects of imagined futures in technological research and innovation processes can be conceived and analyzed. In this paper, all forms of imaginations of technology futures will be called “socio-technical futures” because within them technological developments and social changes are interwoven and inseparably interrelated. In this paper, we discuss why TA should analyze socio-technical futures, how such analyses can grasp the societal conditions that are expressed in the imagined futures and how these become effective in processes of technology development, communication, decision making etc. We raise the question which self-reflexive positioning or possible realignment of TA is needed as a response to its increased concern with assessing and even co-producing socio-technical futures. The latter is often demanded regarding the growing attention by politics and publics to imaginations of futures with wide temporal and spatial reach.Addressee of this paper is the TA community in a broader sense. The aim is to sensitize colleagues for the topic and its challenges, to consolidate discussions and to provide theoretical and methodical suggestions for research in TA and related advisory practices with respect to socio-technical futures. This paper has been originally initiated during the workshop “The present of technological futures-theoretical and methodical challenges for Technology Assessment”, in which all of the paper’s authors participated. The contents of this discussion paper are preliminary results that shall initiate and guide further discussions. (shrink)

This paper describes the Electronic Schoolbag, a digital workspace developed at the University of Savoie (France) and analyses its usages. This online environment is dedicated to the educational world: it offers pupils, students, teachers, school staff, or parents, personal and group workspaces in which individual or collaborative activities can take place. The flexibility of this software, allowing synchronous or asynchronous activities, lies in the “participation model”. This model allows groups themselves to describe and organise their activities. The architecture that permits (...) its implementation in the Electronic Schoolbag workspace is described. The study of the practices of the workspace is then presented. This requires different observation methods, according to the different procedures chosen: real practices provided by quantitative methods (analysis of the logs of the actions and questionnaires) and imagined practices provided by qualitative methods (semi-directive interviews). The results obtained from the university users allow us to assess the evolution of the usages for different periods and on different university sites. The observatory also lets us list the main uses of the Electronic Schoolbag for educative communication (collaborative vs. individual, informative vs. communicative). (shrink)

Publication d'une loi de Delphes qui ne peut être antérieure à 132-135 ap. J.-C, d'après la mention du corrector Aemilius Iuncus. La loi règle la répartition des terres sur une partie du territoire de la cité, après un premier lotissement dont les bénéficiaires voient leurs droits protégés. Cette seconde répartition, qui privilégie les damiurges et les bouleutes au détriment des simples demotes, montre l'existence dans le corps civique de Delphes d'une hiérarchie qui trouve des parallèles dans les cités de la (...) Grèce insulaire et micrasiatique de l'époque impériale. La concession des terres se rapproche de l'« emphytéose », puisque les bénéficiaires auront non pas la pleine propriété, mais la possession illimitée et héréditaire de terres vacantes, qui recevront des améliorations, susceptibles de revenir à la cité avec le fonds faute d'une dévolution successorale normale; cette concession paraît cependant être accordée à titre gratuit. Examen des rapprochements possibles avec les distributions de terres romaines et avec la politique économique impériale, en particulier celle que l'on a attribuée à Hadrien : il est toutefois difficile d'affirmer l'influence et l'intervention directes de Rome à Delphes.

This thesis engages with three topics and the relationships between them: (i) the phenomenon of disagreement (paradigmatically, where one person makes a claim and another denies it); (ii) the normative character of disagreements (the issue of whether, and in what sense, one of the parties is “at fault” for believing something that’s untrue); (iii) the issue of which theory of what truth is can best accommodate the norms relating belief and truth. People disagree about all sorts of things: about whether (...) climate is changing, death penalty is wrong, sushi is delicious, or Louis C.K. is funny. However, even focusing on disagreements in the evaluative domain (e.g., taste, moral and comedic), where people have the intuition that there is ‘no fact of the matter’ about who is right, there are significant differences that require explanation. For instance, disagreement about taste is generally perceived as shallow. People accept to disagree and live comfortably with that fact. By contrast, moral disagreement is perceived as deep and sometimes hard to tolerate. Comedic disagreement is similar to taste. However, it may involve an element of ‘intellectual snobbery’ that is absent in taste disagreement. The immediate questions are whether these contrasts allow of precise characterization and what is responsible for them. I argue that, once a case is made for the truth-aptness of judgments in these areas, the contrast can be explained in terms of variable normative function of truth – as exerting a lightweight normative constraint in the domain of taste and a stricter constraint in the moral domain. In particular I claim that while truth in the moral domain exerts a sui generis deontic control, this normative feature of truth is silent in both the taste and the comedic domains. This leads me to investigate how to conceive of truth in the light of normative variability. I argue that an amended version of deflationism – minimally inflated deflationism – can account for the normative variability of truth. (shrink)

In this paper, I attend to the ontological shift in Merleau-Ponty’s later writing and suggest that this conceptual turn opens the space for questions of the latent sense of the sensible foreclosed by dualist accounts and propositional theories of meaning. By attending to the Nature Lectures, I claim that there is a sens [meaning and orientation] of nature whose regulatory principle ought to be found in nature itself. This is to say that there is a normativity of nature that, albeit (...) not exclusive of sociocultural-linguistic norms, is irreducible to them. As I argue, this normativity is a “transspatializing and transtemporalizing”: it transverses its carnal manifestations, thereby inaugurating and becoming traceable within their materialization while remaining invisible in its excess or poietic renewing. I conclude by attending to the question of the “latent sense” of nature, suggesting that this sense is not conceptual or propositional, but intuitive as in the sense of right and left, a sense that is distributed across spatio-temporal individuals and emerges via the play of yet-to-be-determined incarnate manifestations.Dans cet article, j’aborde le tournant ontologique du dernier Merleau-Ponty et je suggère qu’il implique une interrogation sur le sens latent du sensible, exclu par les approches dualistes ainsi que par les théories propositionnelles de la signification. En analysant les cours sur la Nature, je vise à montrer qu’il y a un sens [signification et direction] de la nature, dont le principe régulateur est à chercher dans la nature elle-même. Cela revient à dire qu’il y a une normativité de la nature qui, bien qu’elle n’exclue pas les normes socio-culturelles-linguistiques, ne leur est pas pour autant réductible. Une telle normativité est « trans-spatiale et trans-temporelle » : elle traverse ses manifestations charnelles, en inaugurant ainsi et en devenant traçable dans ses matérialisations, tout en demeurant invisible dans son excès et dans son renouvellement poïétique. Je termine en abordant la question du « sens latent » de la nature, en suggérant que ce sens n’est ni conceptuel ni propositionnel, mais intuitif, tout comme l’est le sens de la droite et de la gauche, c’est-à-dire un sens qui est distribué à travers les individus spatio-temporels et qui émerge dans le jeu des manifestations incarnées encore-à-déterminer.In questo articolo intendo esaminare la svolta ontologica degli ultimi scritti di Merleau-Ponty per suggerire come questa apra ad un’interrogazione sul senso latente del sensibile, che rimane escluso dagli approcci dualistici e dalle teorie proposizionali del significato. Analizzando i corsi sulla Natura, vorrei mostrare come vi sia un senso [significato e orientamento] della natura il cui principio regolatore deve essere rintracciato nella natura stessa. Ciò significa che vi è una normatività della natura che, benché non esclusiva delle norme socioculturali-linguistiche, è irriducibile ad esse. Questa normatività è “trans-spaziale e trans-temporale”: essa attraversa le sue manifestazioni carnali, inaugurando e divenendo tracciabile nelle sue materializzazioni, pur rimanendo invisibile nella sua eccedenza o rinnovamento poietico. Concludo soffermandomi sulla questione del “senso latente” della natura, suggerendo che questo senso non è concettuale o proposizionale, ma intuitivo al modo del senso della destra e della sinistra, un senso che è distribuito attraverso gli individui spazio-temporali e che emerge nel gioco delle manifestazioni incarnate ancora-da-determinare.

Un debat tres vif eut lieu parmi les commentateurs medioplatoniciens sur le rapport entre la forme du bien de la Republique et le demiurge du Timee. Certains d’entre eux, comme Plutarque et Atticus, parvinrent a identifier ces deux entites, d’autres, comme Numenius, a situer les deux principes dans une relation hierarchique, en attribuant au bien la qualification de ≪premier dieu≫ et de pere et au demiurge celle de ≪second dieu≫ et de producteur. Cet article se propose d’examiner la question de (...) l’identite de la forme du bien avec le demiurge sur des bases nouvelles, en prenant comme point de depart une interpretation metaphorique de la figure du demiurge, qui ne se presente pas comme un principe metaphysique independant, mais comme une description metaphorique de l’element causal‑efficient du monde des formes, c’est a dire du vivant intelligible. Le demiurge coinciderait donc avec la totalite active et dynamique du monde intelligible. Dans la seconde partie de l’article est prise en consideration l’hypothese que la superiorite de la forme du bien par rapport aux autres formes est du meme genre que celle du demiurge, dans la mesure ou le bien aussi peut etre compris comme la totalite du kosmos intelligible. Il s’agit d’une hypothese qui ne va pas sans difficultes, mais qui merite d’etre examinee jusqu’au bout. (shrink)

Since 1993, when Hudelmaier developed an O(n log n)-space decision procedure for propositional Intuitionistic Logic, a lot of work has been done to improve the efficiency of the related proof-search algorithms. In this paper a tableau calculus using the signs T, F and Fc with a new set of rules to treat signed formulas of the kind T((A → B) → C) is provided. The main feature of the calculus is the reduction of both the non-determinism in proof-search and the (...) width of proofs with respect to Hudelmaier's one. These improvements have a significant influence on the performances of the implementation. (shrink)

In questa aula magna, davanti a me, cè un uomo che pesa 73 chili, cioè 113 libbre (per i postmoderni si tratta di due uomini diversi) e, contemporaneamente, uno dei vincitori del premio Mente e Cervello, e un grande filosofo contemporaneo. Questa possibilità non dipende dal fatto che l’aula, come dice il nome, è spaziosa. Searle ci ha insegnato che quando è solo in una stanza d’albergo c’è una sola persona fisica ma più oggetti sociali: un professore, un marito, il (...) titolare di una patente, un... (shrink)
