There is disagreement in the literature about the exact nature of the phenomenon of empathy. There are emotional, cognitive, and conditioning views, applying in varying degrees across species. An adequate description of the ultimate and proximate mechanism can integrate these views. Proximately, the perception of an object's state activates the subject's corresponding representations, which in turn activate somatic and autonomic responses. This mechanism supports basic behaviors that are crucial for the reproductive success of animals living in groups. The Perception-Action Model, (...) together with an understanding of how representations change with experience, can explain the major empirical effects in the literature. It can also predict a variety of empathy disorders. The interaction between the PAM and prefrontal functioning can also explain different levels of empathy across species and age groups. This view can advance our evolutionary understanding of empathy beyond inclusive fitness and reciprocal altruism and can explain different levels of empathy across individuals, species, stages of development, and situations. Key Words: altruism; cognitive empathy ; comparative; emotion; emotional contagion; empathy ; evolution; human; perception-action; perspective taking. (shrink)

In 1999, da Silva, D'Ottaviano and Sette proposed a general definition for the term translation between logics and presented an initial segment of its theory. Logics are characterized, in the most general sense, as sets with consequence relations and translations between logics as consequence-relation preserving maps. In a previous paper the authors introduced the concept of conservative translation between logics and studied some general properties of the co-complete category constituted by logics and conservative translations between them. In this paper we (...) present some conservative translations involving classical logic, Lukasiewicz three-valued system L3, the intuitionistic system I1 and several paraconsistent logics, as for instance Sette's system P1, the D'Ottaviano and da Costa system J3 and da Costa's systems Cn, 1≤ n≤ω.

Only a broad theory that looks across levels of analysis can encompass the many perspectives on the phenomenon of empathy. We address the major points of our commentators by emphasizing that the basic perception-action process, while automatic, is subject to control and modulation, and is greatly affected by experience and context because of the role of representations. The model can explain why empathy seems phenomenologically more effortful than reflexive, and why there are different levels of empathy across individuals, ages, and (...) species. (shrink)

The literary legacy of Aramaic-speaking Christianity consists predominantly of ecclesiastical works—theological treatises , sermons, hymns, and the like; it is for the most part, one must admit, rather dull stuff. Distinguished from the rest, and of peculiar interest to classical students, are secular works, translated from the Greek, which include, apart from medical and scientific treatises, a handful of writings by Plutarch, Lucian, and Themistius. Baumstark suggests that the translator of these three Greek writers be identified as Sargis , a (...) learned priest and ρχιατρός in Theodosiopolis, with a somewhat chequered ecclesiastical career , who is known as the translator of a number of philosophical and medical treatises. Sargis has his place in the history of thought, for it was in the first place through his Syriac translations that the Arabs became acquainted with Galen, whose works eventually assumed almost canonical status with them.

L'A. établit la biographie de Jean le Géomètre en se référant à ses poèmes et à ses épigrammes. Ces poèmes à Basile le Nothos apportent des éclaircissements sur sa carrière comme poète lauréat et sur ses attachements politiques. Il a notamment été renvoyé du service militaire juste après 985 à cause de son attachement à la faction de Basile le Nothos. Ces poèmes à Psenas prouvent indirectement qu'il a vécu au monastère de Kyros vers la fin de sa vie.

When did Livy write his history? How many books had it, and what did the lost ones cover? Such answers as can be given to these questions come almost entirely from the one extant summary, the Periochae. The manuscripts of the Periochae disagree, however, on a matter of considerable interest: out of a hundred or so, only three, supported by a lost fourth, have been cited as adding to the title Ex libro CXXI the subtitle qui editus post excessum Augusti (...) dicitur. When the latest editor, P. Jal in the Collection Budé , declares himself unconvinced of its authenticity , he leaves the reader to decide whether authenticity means truth, authorial origin, or presence in the archetype; but whatever it means, seeds of suspicion have been sown.

LIFE offers various amusements, and anyone these days who can choose among them will come late to the study of hiatus in Greek prose. Germany in the 1880s, so it seems, was less fortunate, and few greater excitements were known to young or old than the hunt for hiatus; but now that we no longer strait-waistcoat our classical authors and the austerity of those times is discredited, few collectors of hiatus are to be found, and there are people even in (...) Germany who have never identified a single specimen. Yet there is nothing to be said for underrating an author' stylistic pretensions, still less for encouraging others to do the same; and the textual critic, whose path is slippery enough at the best of times, can ill afford to dispense with footholds. There has been no broad study of hiatus in Greek prose since 1841, when Benseler in a long and original book De hiatu in oratoribus et historicis Graecis went through the text of 27 authors and attempted to determine their practice.

De ontsluiting van de kosmos, de dynamiek van de schepping, de onrust in ons bestaan doortrekt de systematiek van Dooyeweerd. Zij is wetmatig, subjectief èn objectief. Zij heeft betrekking op de modale aspecten en op de structuren van de werkelijkheid. We kennen natuurlijke ontwikkeling, de evolutie zoals beschreven door de natuurwetenschappen, we kennen de beschavingsgeschiedenis van de mensheid, we kennen de artistieke ontsluiting in de kunsten, we kennen de juridische ontsluiting in de rechtsvorming, we kennen de wetenschappelijke ontsluiting. De ontsluiting (...) is normatief oorzover mensen er een leidende rol in spelen, het script van die rol is de wereldbeschouwing en het middel is de techniek. (shrink)

In lieu of an abstract, here is a brief excerpt of the content: Classics and Complexity in Walden’s “Spring” M. D. USHER In 1843, two years before Henry Thoreau built his cabin at Walden Pond, the Fitchburg Railroad laid down tracks through the woods near the Pond for its line connecting Boston to Fitchburg. The original Fitchburg Line, at 54 miles long, was, until 2010, the longest run in the present -day MBTA Commuter Rail system. And it is one of (...) the oldest railways in New England. By 1900, fortunes swelled and the Fitchburg’s Hoosac Tunnel Line took passengers and goods westward toward Chicago. The Lake Champlain Route connected Boston to points north like Burlington, Vermont. (See Figure 1.) arion 27.1 spring/summer 2019 Figure 1 (left): Advertisement for the Hoosac Tunnel Route in The New England Magazine (Vol. 21, Issue 6, February, 1900).

The Railroad was literally a fixture in Thoreau’s landscape. Its tracks pass remarkably close to Walden Pond (Figure 2), and the Fitchburg Line—both its reality and the specter of it—is practically a character in his writing: “I usually go to the village along its causeway, and am, as it were, related to society by this link,” Thoreau writes in “Sounds,” a chapter of Walden that contains what must be one of the most picturesque odes (or laments) to rail travel and commerce in all of American literature: The engine’s whistle, Thoreau complains, pierces the still silence of his idyllic retreat like a screaming hawk circling a farmer’s field, its billows of steam an ominous harbinger of “this travelling demi-god, this cloud-compeller.”1 Thoreau’s frequent, customary walks into Concord along the railroad tracks took him through a heavily excavated stretch of the line known as the Deep Cut, to which he returned again and again each year in early spring, even after leaving the cabin, to observe and to record his observations. The leaf-shaped sand flows and trickling surface erosion caused by melting frost in the banks of the Deep Cut are elaborately described in Thoreau’s chapter in Walden entitled “Spring,” what Laurence Buell calls the “high point of Thoreau’s epic.”2 And yet, in spite of the universal acclaim of this passage as a literary tour de force, it has not received the full attention it deserves. What warrants fresh consideration first and foremost is “Spring”’s deep-rootedness in classical sources. Many classical influences, allusions, and a good deal of etymological word play have gone so far unnoticed. The chapter is also important because it describes, by intimation, what contemporary scientists now call emergence. Emergent phenomena are properties or behaviors that arise in systems as a result of complex, dynamic interactions amongst constituent parts, including changes to a system brought about by human interventions3—not only, e.g., climate change and wildfires, but also traffic patterns and terrorist networks; kidney function in the body; the rings of Saturn. As he tries to capture the essence of the 114 classics and complexity in WALDEN’s “spring” Deep Cut and interpret its significance, Thoreau adumbrates this concept, but also grapples ingeniously with broader issues of perennial concern—the relationship of Nature to Culture, for example, of Wilderness to Civilization, of Science to the Humanities—making “Spring” not only a probing work of eco-criticism and environmental philosophy, but of scientific reflection and poetic experiment as well. In short, Thoreau’s “Spring” is that rare work of classical reception that transmits both literary and scientific insight. Perhaps at this point, in lieu of accolades, it is best to let Thoreau start speaking for himself. What I offer in the following pages is a commentary on the Deep Cut passage from “Spring.” Classical references and aspects of systems theory will be explained and contextualized as they emerge, as it were, from Thoreau’s text. The whole chapter corresponds to pages 289–308 in Cramer’s edition of Walden—26 paragraphs all told, of which only the relevant ones are printed and annotated here.
