Earlier algebraic semantics for Belnapian modal logics were defined in terms of twist-structures over modal algebras. In this paper we introduce the class of BK -lattices, show that this class coincides with the abstract closure of the class of twist-structures, and it forms a variety. We prove that the lattice of subvarieties of the variety of BK -lattices is dually isomorphic to the lattice of extensions of Belnapian modal logic BK . Finally, we describe invariants determining a twist-structure over a (...) modal algebra. (shrink)
Il passo della Retorica (1358 a 10-21) dove è introdotta la distinzione óo e i' è uno dei più controversi dell'opera aristotelica. Il presente lavoro propone un chiarimento della natura e del ruolo di óo e i' nella costruzione di un'argomentazione dialettico-retorica. Tale chiarimento viene presentato attraverso un confronto tra Topici e Retorica che, se pur espressamente evidenziato da Aristotele stesso, sembra essere stato trascurato da quanti si sono occupati dell'esegesi di tale sezione della Retorica.
A most interesting attempt to weld together a Marxist and a semiotic approach to art. The Marxist insistence upon the historicity of consciousness and the categories in which it expresses itself is accompanied by a systematic semiotically oriented reflection upon the epistemological conditions of meaning. The principal target of della Volpe's project is the Crocean theme that there is something supra-rational conveyed by a work of art, some cosmic feeling or some ineffable content, accessible only to intuition. Della Volpe's position, (...) on the contrary, is rationalist, though with a very specific twist. (shrink)
Colin Cherry's now famous book has been reissued in a third paperback edition in order to put into our hands an economical as well as genial and perspicuous survey of the state and contours of the so-called communication sciences. Cherry's book is properly speaking a manual, as befits its subtitle: A Review, a Survey, and a Criticism. It is composed of eight synthetic and lucid chapters each of which deals with a central area of the processes of communication. Philosophers of (...) diverse persuasions will find here a handy and reliable guide through an enormous mass of materials dealing with both the formal and the material aspects of human communication.

The purpose of this book is to illustrate the heuristic power of semiotics for the interpretation of texts. It oscillates between two poles: the concrete practical pole of encounter with specific texts and the theoretical pole of constructing a model for thematizing both the role of the reader and the structure of the text itself in the creation of meaning. The book consists of eight previously published, but widely scattered, essays of one of semiotics' most talented proponents, and it offers (...) a welcome supplement to the materials contained in his A Theory of Semiotics, whose goal was a systematic overview of the whole field of sign theory.

The interview to Ranabir Samaddar – translated from the original in Bengali by V. Ramaswamy – deals with the Naxalite decade in the perspective of the history it grew from, the history it was part of, and the history it created. The underlying question is: has this decade inaugurated a new phase in the Indian history of rebellions? Samata Biswas and Sandip Bandopadhyay, speaking on behalf of the Calcutta Research Group, engage in a deep dialogue on the novelties and the (...) legacy of the “dangerous decade” that the rulers have only wanted to put to death. The interview explores the evolving modes of popular politics of the past as well, shedding light on the unprecedented and stark opposition between activism and pacifism including submission to law and order. The answers are as much historical as political. (shrink)
Jacques Maritain's An Introduction to Philosophy was first published in 1931. Since then, this book has stood the test of time as a clear guide to what philosophy is and how to philosophize. Inspired by the Thomistic Revival called for by Leo XIII, Maritain relies heavily on Aristotle and St. Thomas Aquinas to shape a philosophy that, far from sectarian theology in disguise, is driven by reason and engages the modern world. Re-released as part of the Sheed & Ward Classic (...) series, An Introduction to Philosophy is sure to enliven the minds of students and general readers for years to come. From the new introduction by Ralph McInerny: You are about to read a magnificent introduction not only to a kind of philosophy but to philosophizing itself. Jacques Maritain was a relatively young man when he wrote this book, but his effort is one that attracts any philosopher more and more as he grows older. However odd and unusual what he says becomes, the philosopher yearns to show how even the most abstruse claims can be put into relation with what the reader already knows. That, in its essence, is what teaching is. In this book, the reader will find a wise and certain guide into philosophizing as such. And, in the end, he will find that what he reads is really only a refinement and development of what he and everybody else already knew. (shrink)
