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.

The four-year wrangle over the ownership of what was then thought to have been the largest known meteorite, recognized near Melbourne in 1860, provides a fine-grained example of the interaction between scientific internationalism, metropolitan appetite for specimens, and colonial civic pride.

Carter has shown that Bosanquet was not the conservative individualist as often supposed, and that he was not hostile to moderate socialism. Bosanquet's logic and metaphysics gives support to this view. But even here he was misunderstood. By over-emphasis on aspects of his philosophical logic, his metaphysics, and practical concerns, we have the most diverse views of what he meant. But taken altogether his whole work has a unity which reconciles collectivist and individualist principles in concrete liberty. The problem of (...) hiatus between Bosanquet's theoretical and practical concerns, which Carter notices, disappears when Bosanquet's philosophical logic is addressed. (shrink)

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)
