Delusion is one of the most intriguing psychopathological phenomena and its conceptualization remains the subject of genuine debate. Claims that it is ill-defined, however, are typically grounded on essentialist expectations that a given definition should capture the core of every instance acknowledged as delusion in the clinical setting.

Na Co nd i ç ã o Huma na, publ i c a do e m1958, Hannah Arendt estabeleceu umadistinção importante entre a “condiçãohumana” e a “nat ur eza humana”. Apar t i r des t e anal i s e f enomenol ógi co,Arendt tentou circunscrever os limitesda “natureza humana”, e responder aosteóricos positivistas que consideravampossível conhecer o quid da naturezabiológica humana. Para Arendt, a açãohumana, a diferença dos eventos ocorrena natureza, consiste numa característicamui t o es peci f (...) i ca a l i ber dade. Comoresultado dele; uma correta compreensãodo fenômeno da condição humana, nãopode ser esgotada por apelar só à dimensãobiológica, devido a que, a ação humananão pode ser exatamente explicada pelasforças que atuam no exterior, o analisedo naturismo é insuficiente. E não podeesgot ar o pr obl ema do f enômeno daliberdade humana.Por sua parte, porém Hans Jonas, nãodes envol veu ampl ament e es t e t ema,inclui em O Principio de Responsabilidade,nos capí t ul os ci nco e sei s, uma duracritica ao projeto marxista que apela aoconceito desenvolvido por Arendt, de homolaborens, o qual é uma das manifestaçõesda “condição humana”.In The Human Condi ti on, published in1958, Hannah Arendt makes an importantdistinction between the “human condition”and t he “human nat ure”. Out of t hi sphenomenological analysis, Arendt triedto circumscribe the limits of the “humannat ur e” and t o r es pond t o pos i t i vi s ttheoreticians who considered possible toknow the essence of the biological humannature. For Arendt, human action, unlikethe events that occur in nature, consists ofa characteristic very specific of freedom.As a result, a correct understanding ofthe phenomenon of human condi ti onis not possible through the biologicaldimension, since human action cannot beproperly explained by the forces that actin the external world. This shows that thenaturalistic analysis is insufficient andcannot deal properly with the phenomenonof human freedom.On the other hand, though Hans Jonas didnot treat completely this problem in his ThePrinciple of Responsibility, he offers a hardcriticism of the Marxist project inspiredin Arendt’s notions, targeting the notion of homo laborens,as one of the manifestations of the “humancondition”.

The series is devoted to the publication of high-level monographs on all areas of mathematical logic and its applications. It is addressed to advanced students and research mathematicians, and may also serve as a guide for lectures and for seminars at the graduate level.

We present the opinion of some authors who believe there is no force between a stationary charge and a stationary resistive wire carrying a constant current. We show that this force is different from zero and present its main components: the force due to the charges induced in the wire by the test charge and a force proportional to the current in the resistive wire. We also discuss briefly a component of the force proportional to the square of the current (...) which should exist according to some models and another component due to the acceleration of the conduction electrons in a curved wire carrying a dc current (centripetal acceleration). Finally, we analyze experiments showing the existence of the electric field proportional to the current in resistive wires. (shrink)

In his thesis Para uma Teoria Geral dos Homomorfismos (1944), the Portuguese mathematician José Sebastião e Silva constructed an abstract or generalized Galois theory, that is intimately linked to F. Klein’s Erlangen Program and that foreshadows some notions and results of today’s model theory; an analogous theory was independently worked out by M. Krasner in 1938. In this paper, we present a version of the theory making use of tools which were not at Silva’s disposal. At the same time, we (...) tried to keep in mind, so much as possible, the gist of his standpoint. (shrink)

Rechtsfilosofische studie over de Italiaanse denker (1668-1744).

A scholium in codex Vaticanus graecus 156 provides evidence that Cassius Dio's Roman History once contained an explicit reference to the ludi saeculares of a.d. 204, something that has been denied in recent scholarship.

Starting from the importance of the figure of the parrhesiastes — the political and therapeutic truth- teller— for Foucault’s understanding of the care of the self, this paper traces the political figuration of the analogy between philosophers and physicians on the one hand, and rhetors and disease on the other in Plato’s Gorgias. I show how rhetoric, in the form of ventriloquism, infects the text itself, and then ask how we account for the effect of the “ contaminated ” philosophical (...) dialogue on our readerly health. Is the text placebo, vaccine, or virus? All of these options, I argue, complicate Foucault’s prescription for parrhesia, requiring us to think anew the continuing political ramifications of the metaphor of care. (shrink)

We give a survey of the study of nonstandard models in recursion theory and reverse mathematics. We discuss the key notions and techniques in effective computability in nonstandard models, and their applications to problems concerning combinatorial principles in subsystems of second order arithmetic. Particular attention is given to principles related to Ramsey’s Theorem for Pairs.

Professor Brenda Baker's recent critique of the Canadian Law Reform Commission's treatment of general standards for criminal liability adds to a growing body of critical theory concerning such standards and their relation to criminal justice. From within the perspective of this same critical movement, I assess the strengths and weaknesses of Professor Baker's efforts and of similar lines of argument in the work of Professor George Fletcher. I find two significant flaws in their shared approach. The first is confusion as (...) to the proper level for analysis of liability standards and, hence, for criticism of the "orthodox" view. This leads Professors Baker and Fletcher to concentrate on issues of culpability rather than responsibility (and to conflate these issues). The second flaw is an error in comprehension of the faults of the orthodox view and, hence, in recognition of the fundamental character of views opposed to that orthodoxy. This leads both theorists to overemphasize a suspect and unilluminating distinction between normative and descriptive approaches to liability problems. The rest of the article is devoted to an overview of my own approach to problems of liability and a general critique of the orthodox view in light of that approach. I argue that the fundamental issue is the relation of liability standards to a conception of agent responsibility. The primary fault of orthodoxy lies, then, in the cognitivist model of responsibility on which it relies. Against this, I propose use of a capacities model of responsibility as the basis for standards of liability. These two models are outlined and compared in final sections. (shrink)

The kleptocratic supremacy of the praetorian prefect C. Fulvius Plautianus was felt throughout the city of Rome, the Empire and even beyond the imperial frontiers. Indeed, for the senatorial historian Dio Cassius, there was no more picturesque demonstration of Plautianus' acquisitiveness than his seizure of strange striped horse-like creatures from ‘islands in the Erythraean Sea’. The passage, as preserved in the text of Xiphilinus' Epitome, reads as follows : καὶ τέλος ἵππους Ἡλίῳ τιγροειδεῖς ἐκ τῶν ἐν τῇ Ἐρυθρᾷ θαλάσσῃ νήσων, (...) πέμψας ἑκατοντάρχους, ἐξέκλεψεν·In the end he even stole tiger-like horses to Helios from the islands in the Erythraean Sea, having sent some centurions to carry out the task.

At some point before the late fifth centurya.d.an unidentified writer compiled and affixed to each book of Dio'sRoman Historyan index, most notably comprising a table of contents and an excerpt of the consularfasti. Of dubious provenance these paratexts have played a peripheral role in the editorial history of the work. Bekker and Dindorf, with somewhat puritanical zeal, removed them from the main text of their editions of theRoman Historyin the belief that they were not by Dio's hand. Conversely, the stereotyped (...) edition of Dio's history produced under the auspices of Karl Tauchnitz at Leipzig in 1818 provided Latin translations of the indices, but omitted the Greek. Dio's more recent editors have restored them to their editions of theRoman History, despite questions over their origins. (shrink)

We are told that when news of Caracalla's death reached Rome a group of senators denounced their former emperor, likening him to all the tyrants of the past who had ruled over them. The senator who recorded these actions, the historian Cassius Dio, does not say which tyrants were listed, but it is likely that such a comprehensive list included the last king of Rome, Tarquinius Superbus, and his son Sextus. The senators' actions were doubtless more an act of group (...) catharsis than a private show of loyalty to their new emperor, Marcus Opellius Macrinus. Yet what the scene reveals perhaps most clearly is the Romanexemplatradition in practice. (shrink)

Discussion about the application of scientific knowledge in robotics in order to build people helpers is widespread. The issue herein addressed is philosophically poignant, that of robots that are “people”. It is currently popular to speak about robots and the image of Man. Behind this lurks the dialogical mind and the questions about the significance of an artificial version of it. Without intending to defend or refute the discourse in favour of ‘recreating’ Man, a lesser familiar question is brought forth: (...) “and what if we were capable of creating a very convincible replica of man (constructing a robot-person), what would the consequences of this be and would we be satisfied with such technology?” Thorny topic; it questions the entire knowledge foundation upon which strong AI/Robotics is positioned. The author argues for improved monitoring of technological progress and thus favours implementing weaker techniques. (shrink)

A coordinate-free formulation is established for (semi) classical particle-field interactions. The exterior language of spacetime chains and De-Rham currents enables the description to include extended strings and membranes besides point particles. Treating physical fields in terms of sections of particular bundles, a unified account of interactions is presented in terms of an intrinsic action principle on a bundle of jets over spacetime. The theory is illustrated by considering the specific model of point particles with intrinsic spin covariantly coupled to theU(1) (...) andSL(2, C) connections describing the electromagnetic and gravitational fields, respectively. The notion of dual spin is examined in this context and coupled equations for this particle-field system are explicitly derived in a local chart. Attention is drawn to the global implications of the theory. (shrink)
