Given that it seems uncontroversial that Socrates displays considerable contempt towards rhetoric in theGorgias,the title of this paper might strike one as an oxymoron. Indeed, a reading of the text has more than once encouraged scholars to posit an Opposition between the elenctic procedures championed by Socrates and the rhetorical procedures of his interlocutors. At least three features have been highlighted that seem to indicate this contrast:1.the Socratic interest in short questions and answers versus his interlocutors’ use of long speeches;2.the (...) Socratic interest in truth regardless of the opinion of the many, the latter seeming an important concern of the rhetorician;3.the supposed Socratic appeal to the intellectual powers of the interlocutor, which is usually contrasted with the appeal to the emotions which is distinctive of rhetoric.

IntroductionInformation and communication technologies are becoming an integral part of medical practice, research and administration and their use will grow as telemedicine and electronic medical record use become part of routine practice. Security in maintaining patient data is important and there is a statuary obligation to do so, but few health professionals have been trained on how to achieve this. There is no information on the use of computers and email by doctors and nurses in South Africa in the workplace (...) and at home, and whether their current computer practices meets legal and ethical requirements. The aims of this study were to determine the use of computers by healthcare practitioners in the workplace and home; the use and approach to data storage, encryption and security of patient data and patient email; and the use of informed consent to transmit data by email.MethodsA self-administered questionnaire was administered to 400 health care providers from the state and private health care sectors. The questionnaire covered computer use in the workplace and at home, sharing of computers, data encryption and storage, email use, encryption of emails and storage, and the use of informed consent for email communication.Results193 doctors and 207 nurses in the private and public sectors completed the questionnaire. Forty (10%) of participants do not use a computer. A third of health professionals were the only users of computers at work or at home. One hundred and ninety-eight respondents (55%) did not know if the data on the computers were encrypted, 132 (36.7%) knew that the data were not encrypted and 30 (8.3%) individuals knew that the data on the computers they were using were encrypted. Few doctors, 58 (16%), received emails from patients, with doctors more likely to receive emails from patients than nurses (p = 0.0025). Thirty-one percent of individuals did not respond to the emails. Emails were saved by 40 (69%) recipients but only 5 (12.5%) doctors encrypted the messages, 19 (47.5%) individuals knowingly did not encrypt and 16 (40.0%) did not know if they encrypted the data. While 20% of health professionals have emailed patient data, but only 41.7% gained consent to do so.ConclusionsMost health professionals as sampled in South Africa are not compliant with the National Health Act or the Electronic Communications Transactions Act of South Africa or guidelines from regulatory bodies when managing patient data on computers. Many appear ignorant or lack the ability to comply with simple data security procedures. (shrink)

Just War scholarship has adapted to contemporary crises and situations. But its adaptation has spurned debate and conversation--a method and means of pushing its thinking forward. Now the Just War tradition risks becoming marginalized. This concern may seem out of place as Just War literature is proliferating, yet this literature remains welded to traditional conceptualizations of Just War. Caron E. Gentry and Amy E. Eckert argue that the tradition needs to be updated to deal with substate actors within the (...) realm of legitimate authority, private military companies, and the questionable moral difference between the use of conventional and nuclear weapons. Additionally, as recent policy makers and scholars have tried to make the Just War criteria legalistic, they have weakened the tradition's ability to draw from and adjust to its contemporaneous setting. The essays in The Future of Just War seek to reorient the tradition around its core concerns of preventing the unjust use of force by states and limiting the harm inflicted on vulnerable populations such as civilian noncombatants. The pursuit of these challenges involves both a reclaiming of traditional Just War principles from those who would push it toward greater permissiveness with respect to war, as well as the application of Just War principles to emerging issues, such as the growing use of robotics in war or the privatization of force. These essays share a commitment to the idea that the tradition is more about a rigorous application of Just War principles than the satisfaction of a checklist of criteria to be met before waging "just" war in the service of national interest.

We analyze the axiomatic strength of the following theorem due to Rival and Sands [28] in the style of reverse mathematics. Every infinite partial order P of finite width contains an infinite chain C such that every element of P is either comparable with no element of C or with infinitely many elements of C. Our main results are the following. The Rival–Sands theorem for infinite partial orders of arbitrary finite width is equivalent to $\mathsf {I}\Sigma ^0_{2} + \mathsf {ADS}$ (...) over $\mathsf {RCA}_0$. For each fixed $k \geq 3$, the Rival–Sands theorem for infinite partial orders of width $\leq \!k$ is equivalent to $\mathsf {ADS}$ over $\mathsf {RCA}_0$. The Rival–Sands theorem for infinite partial orders that are decomposable into the union of two chains is equivalent to $\mathsf {SADS}$ over $\mathsf {RCA}_0$. Here $\mathsf {RCA}_0$ denotes the recursive comprehension axiomatic system, $\mathsf {I}\Sigma ^0_{2}$ denotes the $\Sigma ^0_2$ induction scheme, $\mathsf {ADS}$ denotes the ascending/descending sequence principle, and $\mathsf {SADS}$ denotes the stable ascending/descending sequence principle. To the best of our knowledge, these versions of the Rival–Sands theorem for partial orders are the first examples of theorems from the general mathematics literature whose strength is exactly characterized by $\mathsf {I}\Sigma ^0_{2} + \mathsf {ADS}$, by $\mathsf {ADS}$, and by $\mathsf {SADS}$. Furthermore, we give a new purely combinatorial result by extending the Rival–Sands theorem to infinite partial orders that do not have infinite antichains, and we show that this extension is equivalent to arithmetical comprehension over $\mathsf {RCA}_0$.

Il tema sviluppato nel presente intervento è il rapporto tra narrazione e costruzione storica. Si prenderà in esame l’accezione di narrativa correntemente utilizzata nel mondo storiografico facendola dialogare con il paradigma dei _global middle ages_, espressione coniata nel 2018 dalle storiche Catherine Holmes e Naomi Standen. Per meglio mettere in risalto tali dinamiche un caso di studio sarà offerto dalla vicenda di Federico II, con particolare enfasi alla costruzione biografica e dei miti nel rapporto con le culture altre. Il fine (...) sarà di superare le due tradizionali macro interpretazioni dell’idea di Medioevo, analizzate da Tommaso di Carpegna Falconieri e David Matthews: Medioevo arretrato regno di oscurità e Medioevo vagheggiato come luce del mattino, all’origine di molte identità politiche contemporanee – non ultima quella dell’Unione Europea. _The topic we intend to develop in this essay is the relationship between narration and historical construction. We will examine the meaning behind the current concept of narrative in historiography, with a dialectical approach towards the paradigm of _global Middle Ages_, an expression firstly used by historians Catherine Holmes and Naomi Standen in 2018. To perform an in depth analysis of the abovementioned relationship, we will use as a case study the figure of Frederick II. A significant emphasis will be put on the biographical construction and myths, especially in the relationship with other cultures. The aim of our essay is to provide a framework within it would be easier to overcome the two traditional macro interpretations of Middle Ages, studied by Tommaso di Carpegna Falconieri and David Matthews: Middle Ages as a backward reign of darkness and Middle Ages as the morning light, at the origin of many contemporary political identities – not least that of the European Union_.

Although a great deal has been written on Plato's ethics, his cosmology has not received so much attention in recent times and its importance for his ethical thought has remained underexplored. By offering accounts of Timaeus, Philebus, Politicus and Laws X, the book reveals a strongly symbiotic relation between the cosmic and human sphere. It is argued that in his late period Plato presents a picture of an organic universe, endowed with structure and intrinsic value, which both urges our respect (...) and calls for our responsible intervention. Humans are thus seen as citizens of a university that can provide a context for their flourishing even in the absence of good political institutions. The book sheds light on many intricate metaphysical issues in late Plato and brings out the close connections between his cosmology and the development of his ethics. (shrink)

Estimation and evaluation of individualized treatment rules have been studied extensively, but real-world treatment resource constraints have received limited attention in existing methods. We investigate a setting in which treatment is intervened upon based on covariates to optimize the mean counterfactual outcome under treatment cost constraints when the treatment cost is random. In a particularly interesting special case, an instrumental variable corresponding to encouragement to treatment is intervened upon with constraints on the proportion receiving treatment. For such settings, we first (...) develop a method to estimate optimal individualized treatment rules. We further construct an asymptotically efficient plug-in estimator of the corresponding average treatment effect relative to a given reference rule. (shrink)

In this paper I re-examine the status of the mind-body relation in several of Plato’s late dialogues. A range of views has been attributed to Plato here. For example, it has been thought that Plato is a substance dualist, for whom the mind can exist independently of the body; or an attribute dualist, who has left behind the strong dualistic commitments of the Phaedo by allowing that the mind may be the subject of spatial movements. But even in cases where (...) a classification of Plato as a holder of a particular ontology of the mind has been left undefined, it has been a shared assumption that in the late dialogues the mind itself must be immaterial. I take issue with these various views and show that none of them is necessitated by the text. In the first place, I argue there is strong evidence against the view that Plato should, in his late period, be committed not only to substance dualism, but also to attribute dualism. Furthermore, it is possible that Plato may have allowed that the mind itself be a three-dimensional corporeal entity (in a way that sets up a precedent for later Stoic developments). But even if this is not the only possible reading of the text, it is shown how at any rate the mind must be seen in late Plato as the principle of organization of a body and ontologically inseparable from it. Despite prima facie affinities with Aristotle here, we shall see a Plato emerge for whom the mind (without exception) and the body cannot exist without one another – a thesis more radical than that of Aristotle’s. To bring out the provocative nature of this suggestion, I start, in section I, by laying out the state of the question and compare what I shall argue is the late Platonic view with standard interpretations of his previous work, stressing the historical force that I expect this thesis to have. Afterwards, in three respective sections, I proceed to pay heed to relevant passages in the Timaeus, Philebus and Laws in order to establish the main point of this paper. Finally, in section V, I consider the challenge apparently introduced against my thesis by Plato’s occasional talk of immortality and eschatology in those dialogues, and argue instead that many of those passages add further strength to the view defended in this essay.

This paper re-evaluates the role that Plato confers to pleasure in the "Philebus." According to leading interpretations, Plato there downplays the role of pleasure, or indeed rejects hedonism altogether. Thus, scholars such as D. Frede have taken the "mixed life" of pleasure and intelligence initially submitted in the "Philebus" to be conceded by Socrates only as a remedial good, second to a life of neutral condition, where one would experience no pleasure and pain. Even more strongly, scholars such as Irwin (...) have seen the "Philebus'" arguments against false pleasures as an actual attack on hedonism, showing -- in Irwin's words -- "why maximization of pleasure cannot be a reasonable policy for the best life." Against these claims, I argue that the mixed life of pleasure and intelligence is presented in the "Philebus" as a first best and not just as a second best for humans, and that, accordingly, Socrates proposes to incorporate -- rather than reject -- pleasure as one of the intrinsically desirable aspects of the happy life. Thus, I offer alternative readings of controversial passages that have given rise to the prevalent interpretation criticized here, and advance positive evidence that at least some pleasures are seen by Plato as inherently good. In addition, I demonstrate that Plato's arguments against false pleasures do not by themselves constitute an attack on hedonism. Rather, they can be seen as a strategy to show the hedonist that, in order to be a maximal, or even a consistent, hedonist, he should go for true, and not fake pleasures, if after all pleasure is the object of his pursuit. But, since this cannot be achieved without intelligence, then the mixed life of pleasure and intelligence is to be accepted even by hedonist themselves. (shrink)

THE TENTH BOOK OF THE LAWS, which contains Plato's last word on cosmology and theology, has often been considered as presenting Plato's views in a more exoteric way in contrast with the more esoteric style of the Timaeus. And there are good reasons to think that this view is correct. Whereas the Timaeus stresses that "to find the maker and father of this All is difficult, and, having found it, it is impossible to communicate it to the crowd", Plato is (...) in Laws 10 intending to establish a "proemium" or rational foundation for his laws against impiety, which are supposed to be known by all. In this proemium Plato tries to argue for three propositions: that the gods exist ; that they take care of human affairs ; that they cannot be bribed by sacrifices or prayers. The underlying assumption is that learning these facts about the gods will also help to prevent impiety which, like any kind of vice, is often due to ignorance. (shrink)

Privacy laws are fundamental to protecting individual freedom and autonomy against the tyranny of the majority, and the social orthodoxy imposed through gossip. While it is widely recognized within academic debate that there are limits to freedom of expression, there is little debate about the limits to the right of privacy. We argue that the public interest is a limit to the right of privacy, mediating between the rights of expression and freedom and the flow of information. In doing so, (...) it clarifies not only when invasions of privacy are morally justified, but when claims to privacy are morally unjustified. (shrink)

In A Philosophy of Luxury Lambert Wiesing offre una trattazione originale del concetto di lusso in una prospettiva meramente estetica. Avendo escluso ogni relazione con concetti sociali, quali prestigio, ostentazione, status, Wiesing dichiara che per lusso si deve intendere un’esperienza estetica di tipo particolare. Poiché solo l’uomo indulge nel lusso, ciò che va analizzato è la relazione che intercorre tra un soggetto e un dato oggetto, prescindendo dalle qualità estetiche proprie di quest...

In this paper, I set out to refute several charges that have recently been raised against Plato’s attitude toward the environment and to present him under a new light of relevance for the contemporary environmental debate. For this purpose, I assess the meaning of Plato’s metaphysical dualism, his notion of nature and teleology, and the kind of value that he attributes to animals, plants, and the land in general. I thus show how Plato’s organicist view of the universe endows it (...) with an intrinsic value that is over and above each of its parts, including humans, and provides an argument for the preservation of species of nonhuman animals, which in many relevant ways are not ranked below the human species. In addition, I show how Plato’s dialogues provide good evidence for human concern about the environment and how such a concern is promoted rather than hindered by his nonanthropocentric notion of teleology.

In the thesis some combinatorial statements are analysed from the reverse mathematics point of view. Reverse mathematics is a research program, which dates back to the Seventies, interested in finding the exact strength, measured in terms of set-existence axioms, of theorems from ordinary non set-theoretic mathematics. After a brief introduction to the subject, an on-line (incremental) algorithm to transitively reorient infinite pseudo-transitive oriented graphs is defined. This implies that a theorem of Ghouila-Houri is provable in RCA_0 and hence is computably (...) true. Interval graphs and interval orders are the common theme of the second part of the thesis. A chapter is devoted to analyse the relative strength of different characterisations of countable interval graphs and to study the interplay between countable interval graphs and countable interval orders. In this context the theme of unique orderability of interval graphs arises, which is studied in the following chapter. The last chapter about interval orders inspects the strength of some statements involving the dimension of countable interval orders. The third part is devoted to the analysis of two theorems proved by Rival and Sands in 1980. The first principle states that each infinite graph contains an infinite subgraph such that each vertex of the graph is adjacent either to none, or to one or to infinitely many vertices of the subgraph. This statement, restricted to countable graphs, is proved to be equivalent to ACA_0 and hence to be stronger than Ramsey's theorem for pairs, despite the similarity of partial order with finite width contains an infinite chain such that each point of the poset is comparable either to none or to infinitely many points of the chain. For each k less than or equal to 3, the latter principle restricted to countable poset of width k is proved to be equivalent to ADS. Some complementary results are presented in the thesis. (shrink)
