Our aim is to propose several itineraries which follow the scenario having as a first step Euclid’s Fifth Postulate; as a second step the Bolyai–Lobachevsky’s non-Euclidean geometries and as a third step Einstein’s relativity theory. The role of Euclid’s fifth postulate is successively assumed by Archimedes’ axiom; Zermelo’s choice axiom; Cantor’s continuum hypothesis; von Neumann’s foundation axiom for set theory; Church–Turing thesis and Turing’s computability; the validity of classical logic under the form of the principles of identity, non-contradiction and excluded (...) middle; the macroscopic universe assumed as form of existence, including the fact that humans are macroscopic beings; human language and semiosis assumed as the unique way to approach understanding and communication; the old Greek ideal of order, symmetry and harmony, adopted for representation of the world in Art and Poetry. The common denominator of these starting steps is the fact that they all correspond to the sensorial-empirical perception of the world. We point out the strong interaction among the steps corresponding, in these different itineraries, to Einstein’s relativity theory. We infer in this way the need of a transdisciplinary approach.

Inspired by a mathematical ecology of thearre and the eco-grammar systems, this paper gives a brief analysis of simple cellular automata games in order to demonstrate their primary semiotic features. In particular, the behaviour of configurations in Conway's game of life is compared to several general features of Uexküll's concept of Umwelt. It is concluded that ecological processes have a fundamental semiotic dimension.

In lieu of an abstract, here is a brief excerpt of the content:Some Sources for Hume's Opening Remarks to Treatise LIVJII Graham Solomon Hume opens Book I, Part IV, Section III of the Treatise with these remarks: Several moralists have recommended it as an excellent method ofbecoming acquainted with our own hearts, and knowing our progress in virtue, to recollect our dreams in a morning, and examine them with the same rigour, that we wou'd our most serious and deliberate (...) actions. Our character is the same throughout, say they, and appears best where artifice, fear, and policy have no place, and men can neither be hypocrites with themselves nor others. The generosity, or baseness of our temper, our meekness or cruelty, our courage or pusilanimity, influence the fictions of the imagination with the most unbounded liberty, and discover themselves in the mostglaring colours. Who were these moralists? One looks in vain in the work of Malebranche, Locke, Shaftesbury and Hutcheson for such a recommendation. Did anyone make that recommendation? One moralist who did was "John Shadow," in a letter to Joseph Addison published in The Spectator, no. 586, 27 August 1714. Addison introduces Shadow's letter with the remark that it "is built upon a thought that is new, and very well carried on; for which Reasons I shall give it to the Publick without Alteration, Addition, or Amendment." I quote at length, for easy comparison with Hume: Sir, It was a good Piece of Advice which Pythagoras gave to his Scholars. That every Night before they slept they should examine what theyhad been a doing that Day, and so discover what Actions were worthy of Pursuit to Morrow, and what little Vices were to be prevented from slipping unawares into a Habit. If I might second the Philosopher's Advice, it should be mine, That in a morning before my Scholar rose, he should consider what he had been about that Night, and with the Volume XVI Number 1 57 GRAHAM SOLOMON same Strictness, as if the Condition, he has believed himself to be in, was real. Such a Scrutiny into the Actions ofhis Fancy must be of considerable Advantage, for this Reason, Because the Circumstances which a Man imagines himself in during Sleep, are generally such as entirely favour his Inclinations good or bad, and give him imaginary Opportunities of pursuingthem to the utmost; so thathis Temper will lye fairly open to his View, while he considers howitis moved when free from those Constraints which the Accidents ofreal Life put it under. Dreams are certainly the Result of our waking Thoughts, and our daily Hopes and Fears are what give the mind such nimble Relishes of Pleasure, and such severe Touches ofPain, in its Midnight Rambles. AMan that murders his Enemy, or deserts his Friend in a Dream, had need to guard his Temper against Revenge and Ingratitude, and take heed that he be not tempted to do a vile thing in Pursuit of false, or the Neglect of true Honour... I think it has been observed in the Course of your Papers, how much one's Happiness or Misery may depend upon the Imagination: ofwhich Truth those strange Workings ofFancy in Sleep are no inconsiderable Instances; so that not only the Advantage a Man has ofmaking Discoveries ofhimself, but a Regard to his own Ease or Disquiet, may induce him to accept ofmy Advice... Shadow has been identified as the poet John Byrom by various of the later editors of The Spectator? Of these, D. F. Bond footnotes Byrom's reference to Pythagoras, noting the publication in English of André Dacier's The Life ofPythagoras, with his Symbolism and Golden Verses; together with the Life ofHierocles, and his Commentaries upon the Verses. Bond notes Hierodes' comments on the following Verses: Never suffer Sleep to close thy Eye-lids, after thy going to Bed, Till thou hast examin'd by thy Reason all thy Actions of the Day Wherein have I done amiss? What have I done? What have I omitted that I ought to have done? If in this Examination, thou find that thou hast done amiss, reprimand thy self severely for it: And if thou has done any Good, rejoice. Dacier cites Porphyry and Marcus Aurelius... (shrink)

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

This paper develops a non-relativist version of contextualism about knowledge. It is argued that a plausible contextualism must take into account three features of our practice of attributing knowledge: (1) knowledge-attributions follow a default-and-challenge pattern; (2) there are preconditions for a belief's enjoying the status of being justified by default (e.g. being orthodox); and (3) for an error-possibility to be a serious challenge, there has to be positive evidence that the possibility might be realized in the given situation. It is (...) argued that standard "semantic" versions of contextualism (e.g. those of Lewis, Cohen, DeRose) fail to take these features into account, which makes them overly hospitable to the sceptic, and that Williams' version of contextualism, although incorporating (1), fails to do justice to (2) and (3). According to the contextualism developed here, although epistemic standards vary with the context, the truth-value of particular knowledge-attributions does not. Contexts here are understood as being constituted by two elements: an epistemic practice (a rule-governed social practice such as a scientific discipline, the law, a craft etc., in which knowledge-claims are evaluated according to specific standards) and the "facts of the matter" (i.e. those facts which, together with the epistemic standards in question, determine which error-possibilities are relevant and thus have to be eliminated for a knowledge-claim to be true). If there are several epistemic practices, and thus several contexts, in which a knowledge-claim can be evaluated, it is the "strictest" practice that counts. In this way, the counterintuitive consequence of other versions of contextualism that the same knowledge-claim can be true in one context, but false in another, can be avoided. At the same time, scepticism can be resisted since even in the "strictest" epistemic practices, error-possibilities become relevant only when backed by positive evidence that they might in fact obtain.

Reviews the book, Upheavals of thought: The intelligence of emotions by Martha C. Nussbaum . Drawing from an astounding array of sources, Nussbaum argues against the common understanding of emotions as irrational and animalistic impulses disconnected from our thoughts and reason. Rather, she argues that emotions are highly discriminating responses to what is of value and importance that are, therefore, suffused with intelligence and discernment. Nussbaum explores the structure of a wide range of emotions, in particular, compassion and love, in (...) order to show that there can be no adequate ethical theory without an adequate theory of emotional experience and meaning. 2012 APA, all rights reserved).

Researchers have long suspected that grapheme-color synaesthesia is useful, but research on its utility has so far focused primarily on episodic memory and perceptual discrimination. Here we ask whether it can be harnessed during rule-based Category learning. Participants learned through trial and error to classify grapheme pairs that were organized into categories on the basis of their associated synaesthetic colors. The performance of synaesthetes was similar to non-synaesthetes viewing graphemes that were physically colored in the same way. Specifically, synaesthetes learned (...) to categorize stimuli effectively, they were able to transfer this learning to novel stimuli, and they falsely recognized grapheme-pair foils, all like non-synaesthetes viewing colored graphemes. These findings demonstrate that synaesthesia can be exploited when learning the kind of material taught in many classroom settings. (shrink)

Philosophers since Aristotle have explored emotion, and the study of emotion has always been essential to the love of wisdom. In recent years Anglo-American philosophers have rediscovered and placed new emphasis on this very old discipline. The view that emotions are ripe for philosophical analysis has been supported by a considerable number of excellent publications. In this volume, Robert Solomon brings together some of the best Anglo-American philosophers now writing on the philosophy of emotion, with chapters from philosophers who (...) have distinguished themselves in the field of emotion research and have interdisciplinary interests, particularly in the social and biological sciences. The reader will find a lively variety of positions on topics such as the nature of emotion, the category of "emotion," the rationality of emotions, the relationship between an emotion and its expression, the relationship between emotion, motivation, and action, the biological nature versus social construction of emotion, the role of the body in emotion, the extent of freedom and our control of emotions, the relationship between emotion and value, and the very nature and warrant of theories of emotion. In addition, this book acknowledges that it is impossible to study the emotions today without engaging with contemporary psychology and the neurosciences, and moreover engages them with zeal. Thus the essays included here should appeal to a broad spectrum of emotion researchers in the various theoretical, experimental, and clinical branches of psychology, in addition to theorists in philosophy, philosophical psychology, moral psychology, and cognitive science, the social sciences, and literary theory.
