La categoria de passivitat és tan nuclear en la filosofia d’Emmanuel Levinas com en la de Paul Ricoeur. Aquesta categoria està intrínsecament vinculada a una altra que també és crucial: la d’alteritat. Per entendre la proximitat entre aquests dos autors, alhora que per veure’n la distància que els separa, resulta molt revelador prestar atenció, primer, a la manera com cadascun d’ells concep les dues categories i, després, al motiu pel qual mentre en el cas de Levinas el lloc de la (...) passivitat és exclusivament un —la relació amb l’altre—, en el de Ricoeur és triple: la carn o el cos propi, l’altre i la consciència.

The Intimate Resistance is a keen, deeply beautiful reflection on the human condition. The author explains howwe ourselves can warm, protect and guide those around us.

First, this article summarizes the way Jan Patocˇka thinks and updates the classic theme of philosophy as care for the soul. Then goes on to show Jacques Derrida’s significant and unexpected interest in the Czech thinker, and the manner as sharp and respectful as he reads it. Derrida argues that the core of Patocˇka’s approach, under the term “responsibility”, coincides in some sense with that of Emmanuel Levinas; nucleus that has to do, in both authors, with the essence of “religion”.

El cuidado de sí es cuidado de lo más humano de cada uno de nosotros. La convicción nuclear que lo rige es siempre la misma: que lo humano puede intensificarse y crecer. Y que el peligro reside siempre en la degeneración. Intensificar lo humano es ir hacia lo “más humano”. En absoluto se busca la “superación” o el “más allá” de lo humano. Este artículo es un intento de relacionar la lectura que hace Foucault del tema del cuidado de sí (...) con la urgente necesidad de repensar hoy el lugar de lo educativo como lugar propio para ese cuidado. Para tal fin, se propone el concepto de altertopía educativa, como lugar, no solo de resistencia al dominio de la banalidad contextual, sino de gestación de la fuerza revolucionaria. (shrink)

Book review of Humano, más humano. Una antropología de la herida infinita Josep Maria Esquirol.

Se trata de un ensayo en el que Josep Maria Esqiurol reflexiona acerca de lo más profundo de lo humano, concluyendo que lo más característico del humano es una suerte de conmoción, un estar efectado por algo, y no algún tipo de poder o capacidad. El enfoque del libro nos presenta una antropología orientada hacia la compañía, el cuidado y el amparo.

Este texto de Esquirol corresponde a su última obra dedicada a la escuela. En ella el autor ha meditado, de manera elocuente y concreta, sobre las formas de la educación y la manera de vivir. Esquirol propone una nueva perspectiva sobre la _escuela_. Esta no es solo el lugar al que se va en cierto momento de la vida, sino en la que el humano permanece, comprendiendo que la educación es un proceso que abarca toda la vida.

The centenary of the birth of Ludwig Wittgenstein provided an opportunity for recovering some of the great Wittgensteinian subjects, for re-examining them and for discussing their implications and relevance. This volume is the result of the interchange that took place in Girona among well-known scholars of Wittgenstein's work in different countries. The eleven contributions are organized into three main subjects: on Wittgenstein's method, on knowledge and meaning, on language and use. This volume is not only the result of the different (...) and mature reflexions of its authors, but in two cases it has also unfortunately become their last contribution to the subject. (shrink)

Argues that Merleau-Ponty’s thought grounds itself on “non-coincidence” or, as he puts it, on “divergence or écart”, “non-transparence” or “non-adequacy”, since neither perception nor knowledge, in his view, actually conveys the things perceived or known. Reality comes up drenched in transcendence, and likewise thought has to span the “uncanny distance” that severs the subject from itself and every object from its own identity. Thus appear groundless an array of received views on the “reversibility” ascribed by Merleau-Ponty to the doublet “distance (...) vs. immediacy”. (shrink)

Attempts to elucidate the tension between the finitist compromise and the ontological scaffolding in Heidegger’s early thought, while acknowledging that this twofold commitment entails a methodology of a bafflingly circular character. This pessimistic claim appears reinforced by the evidence that the grounding of “Being” upon “the beings” cannot exclude the “paradoxical grounding of Being” by “the beings” themselves.

Anàlisi crítica sobre les bases doctrinals de l'ecologisme. Idees i reflexions que trenquen els tòpics més divulgats.

En aquesta arrencada del segle XXI, en què la tecnologia ens afalaga i alhora ens domina, ens calen humanistes que ens ajudin a interpretar la realitat i a tenir criteris per a abordar-la. Josep Maria Puigjaner, l'autor d'aquest llibre, s'ha proposat apropar al lector, a través de la narració d'alguns retalls -reals o imaginaris- de les seves vides, la personalitat de vuit humanistes que ens transmeteren, durant el segle XX, la seva manera d'entendre la vida i l'home. Són (...) escriptors que mereixen el qualificatiu de clàssics, és a dir que parlen des d'una perspectiva interior, profunda i arrelada en el coneixement i en l'experiència del significat de la naturalesa humana i els seus ideals de futur.

In this paper two deductive systems associated with relevance logic are studied from an algebraic point of view. One is defined by the familiar, Hilbert-style, formalization of R; the other one is a weak version of it, called WR, which appears as the semantic entailment of the Meyer-Routley-Fine semantics, and which has already been suggested by Wójcicki for other reasons. This weaker consequence is first defined indirectly, using R, but we prove that the first one turns out to be an (...) axiomatic extension of WR. Moreover we provide WR with a natural Gentzen calculus. It is proved that both deductive systems have the same associated class of algebras but different classes of models on these algebras. The notion of model used here is an abstract logic, that is, a closure operator on an abstract algebra; the abstract logics obtained in the case of WR are also the models, in a natural sense, of the given Gentzen calculus.

En la gran producció filosòfica d’Eusebi Colomer, s’hi poden distingir tres grans centres d’interès particularment destacats. En primer lloc, la seva dedicació a l’estudi del pensament de Ramon Llull i de Nicolau de Cusa. La seva tesi doctoral va mostrar les influències lul·lianes en l’obra de Nicolau de Cusa a partir de les anotacions autògrafes en què el jove Nicolau es feia ressò de les coses que més li interessaven de Llull. El segon gran centre d’interès el van constituir, naturalment, (...) els grans corrents de la filosofia alemanya moderna i contemporània. Des dels anys d’estudiant s’havia familiaritzat particularment amb l’idealisme, la fenomenologia i la filosofia de l’existència. Finalment, el seu tercer centre d’interès va ser el diàleg filosòfico-teològic. Colomer lamentava profundament el divorci produït entre la filosofia i la teologia. Adaptant una coneguda formulació de Kant, pensava que la teologia sense filosofia és cega, però que la filosofia sense teologia és buida. Format en la tradició metafísica espiritualista i defensor de l’humanisme cristià, Colomer es trobava, però, a les antípodes de qualsevol sectarisme o dogmatisme. La seva formació, el seu tarannà i, segurament, els seus enormes coneixements de la història de la filosofia, li havien conferit una gran capacitat per al diàleg. Ell no veia el diàleg com un recurs o com una tàctica, sinó com un element constitutiu de l’ésser humà. \n. (shrink)

A pair of deductive systems (S,S’) is Leibniz-linked when S’ is an extension of S and on every algebra there is a map sending each filter of S to a filter of S’ with the same Leibniz congruence. We study this generalization to arbitrary deductive systems of the notion of the strong version of a protoalgebraic deductive system, studied in earlier papers, and of some results recently found for particular non-protoalgebraic deductive systems. The necessary examples and counterexamples found in the (...) literature are described. (shrink)

Quins són els valors que regeixen la nostra vida? I per què vivim amb aquests valors i no amb uns altres? «Els valors van cap a on anem nosaltres perquè van amb nosaltres. ¬I mentre fem camí o mentre el busquem, els valors ens alimenten», diu el filòsof.

This paper has a very limited scope: it just presents some eIements which may introduce us into a wider investigation on vague predicates. Thus, webegin by pointing out our general conception of Iogic (as a descriptive science of linguistic phenomena). After that, we build up our approach by considering characteristic functions and by trying to make useful the model of logical extension which applies to classical quantifiers.

Daniel Bensaïd was a Marxist philosopher and author of an extensive body of works about political strategy. His writings combine a diversity of singular influences, such as Marx, Lenin, Trotsky and Che Guevara on the one hand, and Benjamin, Péguy and Blanqui on the other. In his work, religious heresies, Marranos, moles and emblematic figures of the resistance to oppression such as Joan of Arc meet with the classic figures of Marxism. The non-linear concept of time and messianic reason support (...) a strategic reading of history and an understanding of political commitment, following Goldmann’s interpretation of Pascal’s Wager as a wager of uncertain outcome.

This is a contribution to the discussion on the role of truth degrees in manyvalued logics from the perspective of abstract algebraic logic. It starts with some thoughts on the so-called Suszko’s Thesis (that every logic is two-valued) and on the conception of semantics that underlies it, which includes the truth-preserving notion of consequence. The alternative usage of truth values in order to define logics that preserve degrees of truth is presented and discussed. Some recent works studying these in the (...) particular cases of Łukasiewicz’s many-valued logics and of logics associated with varieties of residuated lattices are also presented. Finally the extension of this paradigm to other, more general situations is discussed, highlighting the need for philosophical or applied motivations in the selection of the truth degrees, due both to the interpretation of the idea of truth degree and to some mathematical difficulties.

A filter of a sentential logic ? is Leibniz when it is the smallest one among all the ?-filters on the same algebra having the same Leibniz congruence. This paper studies these filters and the sentential logic ?+ defined by the class of all ?-matrices whose filter is Leibniz, which is called the strong version of ?, in the context of protoalgebraic logics with theorems. Topics studied include an enhanced Correspondence Theorem, characterizations of the weak algebraizability of ?+ and of (...) the explicit definability of Leibniz filters, and several theorems of transfer of metalogical properties from ? to ?+. For finitely equivalential logics stronger results are obtained. Besides the general theory, the paper examines the examples of modal logics, quantum logics and Łukasiewicz's finitely-valued logics. One finds that in some cases the existence of a weak and a strong version of a logic corresponds to well-known situations in the literature, such as the local and the global consequences for normal modal logics; while in others these constructions give an independent interest to the study of other lesser-known logics, such as the lattice-based many-valued logics.

ukasiewicz''s four-valued modal logic is surveyed and analyzed, together with ukasiewicz''s motivations to develop it. A faithful interpretation of it in classical (non-modal) two-valued logic is presented, and some consequences are drawn concerning its classification and its algebraic behaviour. Some counter-intuitive aspects of this logic are discussed in the light of the presented results, ukasiewicz''s own texts, and related literature.

Łukasiewicz’s infinite-valued logic is commonly defined as the set of formulas that take the value 1 under all evaluations in the Łukasiewicz algebra on the unit real interval. In the literature a deductive system axiomatized in a Hilbert style was associated to it, and was later shown to be semantically defined from Łukasiewicz algebra by using a “truth-preserving” scheme. This deductive system is algebraizable, non-selfextensional and does not satisfy the deduction theorem. In addition, there exists no Gentzen calculus fully adequate (...) for it. Another presentation of the same deductive system can be obtained from a substructural Gentzen calculus. In this paper we use the framework of abstract algebraic logic to study a different deductive system which uses the aforementioned algebra under a scheme of “preservation of degrees of truth”. We characterize the resulting deductive system in a natural way by using the lattice filters of Wajsberg algebras, and also by using a structural Gentzen calculus, which is shown to be fully adequate for it. This logic is an interesting example for the general theory: it is selfextensional, non-protoalgebraic, and satisfies a “graded” deduction theorem. Moreover, the Gentzen system is algebraizable. The first deductive system mentioned turns out to be the extension of the second by the rule of Modus Ponens. (shrink)
