Kripke-style models with two accessibility relations, one intuitionistic and the other modal, are given for analogues of the modal systemK based on Heyting's prepositional logic. It is shown that these two relations can combine with each other in various ways. Soundness and completeness are proved for systems with only the necessity operator, or only the possibility operator, or both. Embeddings in modal systems with several modal operators, based on classical propositional logic, are also considered. This paper lays the ground for (...) an investigation of intuitionistic analogues of systems stronger thanK. A brief survey is given of the existing literature on intuitionistic modal logic.

Many tasks in statistical and causal inference can be construed as problems of entailment in a suitable formal language. We ask whether those problems are more difficult, from a computational perspective, for causal probabilistic languages than for pure probabilistic (or “associational”) languages. Despite several senses in which causal reasoning is indeed more complex—both expressively and inferentially—we show that causal entailment (or satisfiability) problems can be systematically and robustly reduced to purely probabilistic problems. Thus there is no jump in computational complexity. (...) Along the way we answer several open problems concerning the complexity of well-known probability logics, in particular demonstrating the ${\exists \mathbb {R}}$ -completeness of a polynomial probability calculus, as well as a seemingly much simpler system, the logic of comparative conditional probability.

Hannah Arendt is famous for her influential and innovative analysis of totalitarianism. However, her thinking on political systems and ideologies is far from limited to this theorization. Arendt also criti-cizes modern liberalism and its ideological framework. Indeed, Arendt’s thought reveals many of the political consequences of world-lessness, the loss of the world in contemporary times, particularly in terms of a sense of disempowerment and the advent of a technical vision of politics. This article looks at the political effects of world-lessness, (...) exploring the emerging opposition between liberal post-politics and conservative hyper-politics. This critique of Arendt’s thought can help us better understand the issues and questions raised by liberalism. (shrink)

Slovak Academic Philosophy: Its Origins, Development and Current State The paper introduces the foreign reader to the main factors associated with the emergence of Slovak academic philosophy as well as to the ways in which it has developed, and also to those factors that have complicated or delayed its progress since 1921 when the Faculty of Philosophy, along with its Philosophical Seminars, began functioning at the newly-founded University of Comenius (1919), up to the present day.

Comment rapprocher Diderot et Watteau, qui représentent deux conceptions artistiques foncièrement différentes? C'est dans une perspective interdisciplinaire, au croisement de la théorie de l'art, de la critique d'art et des études littéraires que les essais rassemblés dans le présent recueil proposent une réflexion peu conventionnelle sur les perceptions de l'image au xvii siècle. Au fil de notions difficilement définissables, telles que la mélancolie, le rêve, la grâce ou la légèreté, aptes cependant à s'ériger en concepts esthétiques généraux, les études réunies (...) ici visent à tracer les contours d'une poétique de l'image. À travers ces catégories, qui peuvent en effet servir de lien entre Diderot et Watteau, l'ouvrage prétend porter un éclairage nouveau sur les questions artistiques et contribuer ainsi à la réinterprétation des notions propres à la théorie de l'art française de l'époque classique."--Page 4 of cover.
