This essay deals with the concept of negation in Deontics. In relation with this concept, the polish logician Jerzy Sztykgold seems to put forward these two thesis: a) a norm may have a negation; b) a norm may be a negation. Sztykgold studies the concept of Inegation of a norm through the analysis of other two concepts of a right or of a duty and the concept of opposition of behaviour), and, as early as 1936, he puts hirnself in a (...) clear position in relation to the problem of the possibility of a logic of norms: There is a deontic analogonof truth, which is the słuszność consequently, for the norms, entities of which the słuszność is predicated, are valid the thesis of the propositional logic that are valid for the apophantic sentences.

"It is the purpose of this article to attempt to re-examine the account of Thrasymachus' doctrine in Plato's Republic, and to show how it can form a self-consistent whole. [...] In this paper it is maintained that Thrasymachus is holding a form of [natural right]".

This book offers an introduction to the Sophists of fifth-century Athens and a new overall interpretation of their thought. Since Plato first animadverted on their activities, the Sophists have commonly been presented as little better than intellectual mountebanks - a picture which Professor Kerferd forcefully challenges here. Interpreting the evidence with care, he shows them to have been part of an exciting and historically crucial intellectual movement. At the centre of their teaching was a form of relativism, most famously expressed (...) by Protagoras as 'Man is the measure of all things', and which they developed in a wide range of views - on knowledge and argument, virtue, government, society, and the gods. On all these subjects the Sophists did far more than simply provoke Plato to thought. Their contributions were substantial and serious; they inaugurated the debate on many central philosophical questions and decisively shifted the focus of philosophical attention from the cosmos to man.

In conveying experiences of meditation, the question of what exceeds or should resist description has been a recurrent topic of commentary in a wide array of literature -- including religious doctrine, meditation guides, and contextual accounts written by historians and social scientists. Yet, to date, this question has not significantly informed neuroscientific studies on the effects of meditation on brain and behaviour, in large part -- but not wholly -- because of the disregard for first-person accounts of experience that still (...) characterizes neuroscience in general. By juxtaposing perspectives from non-neuroscientific accounts on the tensions and questions raised by what is and is not expressed or expressible in words, this article paves the way for a new set of possibilities in experimental contemplative neuroscience.

In the article "The Epistemological Nature of Information Modeling" [Gnoseologicheskaia priroda informatsionnogo modelirovaniia], Voprosy filosofii, 1963, No. 10, Academician V. M. Glushkov examines two important methodological aspects of the modeling of natural objects and phenomena in the contemporary natural sciences. The first consists of the informational nature of the models created, and the second of their dynamism. The dynamic nature of today's models in the natural sciences means that it is not so much the material structure of the object that (...) is modeled as its behavior and functions in some sphere of natural phenomena. In this sense, the models under examination may also be termed functional, as distinct from the structural models pertaining to a static description of objects. (shrink)

Plato's Sophist begins with an attempt to arrive by division at a definition of a Sophist. In the course of the attempt six different descriptions are discussed and the results summarized at 231 c-e. A seventh and final account may be said to occupy the whole of the rest of the dialogue, including the long digression on negative statements. The first five divisions characterize with a considerable amount of satire different types of sophist, or more probably different aspects of the (...) sophistic art. The sixth division is very different. To quote Cornford's words, ‘satire is dropped. The tone is serious and sympathetic, towards the close it becomes eloquent’. (shrink)
