A continuoxis t- norm is a continuous map * from [0, 1]² into [0,1] such that is a commutative totally ordered monoid. Since the natural ordering on [0,1] is a complete lattice ordering, each continuous t-norm induces naturally a residuation → and becomes a commutative naturally ordered residuated monoid, also called a hoop. The variety of basic hoops is precisely the variety generated by all algebras, where * is a continuous t-norm. In this paper we investigate the structure of the (...) variety of basic hoops and some of its subvarieties. In particular we provide a complete description of the finite subdirectly irreducible basic hoops, and we show that the variety of basic hoops is generated as a quasivariety by its finite algebras. We extend these results to Hájek's BL-algebras, and we give an alternative proof of the fact that the variety of BL-algebras is generated by all algebras arising from continuous t-norms on [ 0,1] and their residua. The last part of the paper is devoted to the investigation of the subreducts of BL- algebras, of Gödel algebras and of product algebras. (shrink)

The view of Deitz and Arrington that Wittgenstein's ordinary language philosophy allows behaviorism to use cognitive terms with a behavioristic system is disputed and an alternative is suggested.

In the contemporary period of history, so deeply contradictory and in many respects conflict ridden, eschatological themes, predictions of universal catastrophe and the ecological or nuclear destruction of mankind, and other motifs of the end of human history have become unprecedentedly widespread and greatly attractive. Despite the huge stores of scientific knowledge accumulated in the past few decades, many people are being drawn more and more into the stream of mystical monstrous visions and are beginning to connect the end of (...) the second millennium with implausible, obsessive apocalyptic presentiments with regard to the world as a whole as well as to our own Russian history. Soothsayers have appeared who have begun to link the phenomena of disintegration and decline and the destruction of political, ethical, and aesthetic criteria being manifested in our country in one way or another directly with the end of Russian history, with the final act of the Russian historical drama. In the sphere of concrete theoretical and philosophical-sociological knowledge, notions of the limit of historical progress, that history has fundamentally, in its essentials, run its course and that from now on the future will bring nothing essentially new, are being put forward and defended.

McGavin, PA The Holy Father often speaks without a prepared text, and it is amazing how accurately he reads in transcription. This was brilliantly so in Light of the World interviews. Even his brief words at pages 118-119 on condoms - so breathlessly and inaccurately treated in the media - are so cast as to withstand close scrutiny. It is with this recognition that I address his lack of precision and perception in speaking on the question of homosexuality and sacred (...) ordination. (shrink)

Antisthenes (c. 445- c. 365 BC), was a prominent follower of Socrates and bitter rival of Plato. In this revisionary account of his philosophy in all its aspects, P. A. Meijer claims that Plato and Aristotle have corrupted our perspective on this witty and ingenious thinker. The first part of the book reexamines afresh Antisthenes' ideas about definition and predication and concludes from these that Antisthenes never held the (in)famous theory that contradiction is impossible. The second part of the book (...) argues that Antisthenes' logical theories bear directly on his activities as an exegete of Homer and hence as a theological thinker. Part three, finally, offers innovative readings of Antisthenes' ethical fragments. (shrink)

Сборник статии и интервюта на академик Едуард Павлович Кругляков, редовен член на Руската академия на науките, физик с висок международен научен престиж и председател на Комисията за борба с лъженауката и с фалшифицирането на научните изследвания към Руската академия на науките. Книгата е ориентирана към съвремието, свързано с настъпването на лъженауката в Русия, и много по-слабо засяга проблемите на догматичната и силово налагана лъженаука през сталиновия период.
