Having, as it is generally agreed, failed to destroy the computational conception of mind with the G\"{o}delian attack he articulated in his {\em The Emperor's New Mind}, Penrose has returned, armed with a more elaborate and more fastidious G\"{o}delian case, expressed in and 3 of his {\em Shadows of the Mind}. The core argument in these chapters is enthymematic, and when formalized, a remarkable number of technical glitches come to light. Over and above these defects, the argument, at best, is (...) an instance of either the fallacy of denying the antecedent, the fallacy of {\em petitio principii}, or the fallacy of equivocation. More recently, writing in response to his critics in the electronic journal {\em Psyche}, Penrose has offered a G\"{o}delian case designed to improve on the version presented in {\em SOTM}. But this version is yet again another failure. In falling prey to the errors we uncover, Penrose's new G\"{o}delian case is unmasked as the same confused refrain J.R. Lucas initiated 35 years ago.

We show that the name “Lucas-Penrose thesis” encompasses several different theses. All these theses refer to extremely vague concepts, and so are either practically meaningless, or obviously false. The arguments for the various theses, in turn, are based on confusions with regard to the meaning of these vague notions, and on unjustified hidden assumptions concerning them. All these observations are true also for all interesting versions of the much weaker thesis known as “Gö- del disjunction”. Our (...) main conclusions are that pure mathematical theorems cannot decide alone any question which is not purely mathematical, and that an argument that cannot be fully formalized cannot be taken as a mathematical proof.

This piece outlines concrete cases of benefit sharing that occur in relation to the sharing of human (biological) samples. For example, it surveys Indonesia’s decision, in 2006, to stop sharing virus samples of H5N1 (avian influenza) with the WHO Global Influenza Surveillance Network (GISN). It also outlines some of the ethical issues that arise in these cases.

Augustine’s discussion of our memoria of the liberal arts in Confessions X poses a series of challenging questions which are best tackled in the broader context of his ideas on teaching, learning, understanding and the acquisition of knowledge. The contents of the liberal arts are stored in our memory (a non-physical and non-spatial receptacle often meta­phorically depicted through spatial imagery) by themselves, and not through images (like the objects of sense-perception) or ‘notions’ (like the affections of the soul). When we (...) learn the disciplinae liberales, actually we do not absorb new information from our teachers, but we are triggered by their words to retrieve from the most remote ‘caves’ of our memory contents already present in a latent form since birth (I address the question of what exactly these con­tents might be). In the Confessions, unlike in earlier writings, Augustine cautiously eschews expressions which might suggest full-blown Platonic recollection of things known in previous lives and subsequently forgotten, and thus presuppose the pre-existence and reincarnation of the soul (not even the claim that cogitare is, literally, ‘re-collecting’ involves recalling forgotten knowledge). I argue that for Augustine divine illumination (as presented, e.g., in the De magistro and the De Trinitate) and recollection are not two rival and incompatible theo­ries, but two different and yet consistent sets of metaphors meant to illustrate the same family of ideas and intuitions (sometimes underdetermined in their details); I also explain why the illumination metaphor ultimately appears more appropriate.

As predicted by Duverger’s Law, the UK has two-party competition in each electoral district. However, there can be different patterns of two-party competition in different districts (currently there are five), so that there have usually been more than two effective parties in the Commons. Since 1874 it has always contained parties fighting seats in only one of the non-English parts of the Union. These parties wish to change the Union by strengthening, weakening, or dissolving it. By calculating the Penrose power (...) index for all parties in the House of Commons for all General Elections since 1874, we identify the occasions on which a party that wished to modify the Union was pivotal. We explain various acts (e.g, the Crofters Act 1886; the first three Irish Home Rule Bills; the Parliament Act 1911) and non-acts (e.g. the failure to enact female suffrage before 1914) by reference to the Penrose indices of the non-English parties. The indices also explain how and why policy towards Scotland, Wales and Northern Ireland changed, and did not change, in the 1970s. (shrink)

In the last few years, various Kantian commentators have drawn attention on a number of features in the self-reference device of transcendental apperception having emerged from the contemporary debate on the irreducibility of self-ascription of thoughts in the first person. Known as I-thoughts, these have suggested a connection between some aspects of Kant’s philosophy and Wittgenstein’s philosophico-linguistic analysis of the grammatical rule of the term I. This paper would like to review some of such correspondences (§§ 1-3), avoiding any mechanical (...) association between Kant and an elusive reading of the I think, e.g. as suggested mutatis mutandis by McDowell and Kitcher (§§ 4-7).

In lieu of an abstract, here is a brief excerpt of the content:FEYERABEND'S EPISTEMOLOGY AND BRECHTS THEORY OF THE DRAMA by S. G. Couvalis In his early paper, "On the Improvement of the Sciences and the Arts," Feyerabend argues that, just as rival hypotheses show the shortcomings of entrenched scientific hypotheses, so theatre which presents hypotheses contrary to common beliefs about human beings shows the shortcomings of these beliefs. It develops understanding of human relations more effectively than intellectual debate because (...) it is a more complex medium whose elements can "represent the contrary hypotheses at the same time."1 He takes Brecht to be the first theorist of such a theatre. I shall argue that Brecht's epistemology is similar to Feyerabend's early epistemology and that his dramatic theory is a consequence of it.2 1 shall also argue, however, that Feyerabend is wrong in saying that Brechtian theatre presents contrary hypotheses at the same time, because plays, like descriptions, are theory-laden and Brecht, in any case, intends to show on stage that tragedies have social origins and not to present contrary hypotheses about human beings. According to Brecht, most people improperly assume that human behavior and social relations follow fixed patterns inherent in nature because they have been unable to compare the human behavior they know with that in other societies. They take what they experience to be typically human. Moreover, they interpret their social world as they have been taught: "A child, living in a world of old men... knows the run of things before he can walk."3 Feyerabend brings out the effect of such training very vividly: "The teaching procedures both shape the 'appearance,' or 'phenomenon' and establish a firm connection with words, so that finally the phenomena seem to speak for themselves...."4 Because these interpretations of the social world which children are taught are descriptive, explanatory, and prescriptive, they are more 117 118Philosophy and Literature complex and more dangerous than the interpretations of physical objects they are taught. For example, children learn different evaluations of precisely the same behavior in males and females through being taught how to describe it. In being taught to describe certain behavior as "manly" they are taught both that it arises from a male's nature and that it is laudable behavior for boys but not for girls. "Manly" behavior in a woman is not "confident" or "forthright," but "aggressive" or "pushy." In order to stop us from regarding traditional behavior patterns and social relations as unchangeable, and to enable us to question our descriptions of them, Brecht argues that the dramatist must cause us to cease to regard such patterns and social relations as familiar givens that can only be described in one way. To achieve this, he must not structure his plays on the Aristotelian model. The Aristotelian model makes audiences incapable of criticizing the dramatic message, imparts the view that the sources of tragedy lie in an inexplicable human essence, and presents social rules as if they were unquestionable natural laws. Instead, he should structure his plays to induce in audiences a scientific attitude to social relations and patterns of behavior. Like Feyerabend, Brecht realizes that a scientific attitude is not displayed by collecting descriptions of experience without considering whether the interpretations contained in the descriptions are correct. In Galileo, his view of those who mechanically describe experience in traditional terms is shown in Galileo's replies to the Aristotelian arguments of Andrea. When Andrea argues, "I can see that the sun's not in the same place in the evening and morning. So it can't stand still. It just can't," Galileo replies, "You 'W! What do you see? You see nothing at all. You're just gaping. Gaping isn't seeing." He then demonstrates to Andrea that the apparent motions of objects need not be their real motions because an apparent motion can be caused in more than one way. 5 Brecht shows that the central question for the scientist is not "How shall I collect descriptions of appearances?" but "What is it that I really perceive and how is it caused?" He argues elsewhere that "there's a vast difference between experiment and experience" because experiments are set up to test... (shrink)

Bietti, Tilston and Bangerter take an evolutionary approach towards memory transmission and storytelling, arguing that storytelling plays a central role in the creation and transmission of cultural information. They suggest that storytelling is a vehicle to transmit survival‐related information that helps to avoid the costs involved in the first‐hand acquisition of that information and contributes to the maintenance of social bonds and group‐level cooperation. Furthermore, Bietti et al. argue that, going beyond storytelling’s individualist role of manipulating the audience to enhance (...) fitness of the narrator, that these adaptive functions of storytelling may well be assigned to other forms of language use besides narration (e.g., instructional discourse and argumentation). Based on this evidence, Bietti and colleagues claim that the specific adaptive function of storytelling lies in making sense of non‐routine, uncertain, or novel situations, thereby enabling collective sensemaking.

(...) The volume also contains a helpful chronology to the major scientific and philosophical events in the twentieth century. It also provides an extensive glossary of technical terms in the notes on major figures in these fields. (shrink)

In spite of the labours of Sedlmayer,1 Ehwald2 and Palmer,3 it cannot be said that there exists a completely satisfactory edition of Ovid's Heroides. One or all of these editors sometimes leave a corrupted text, sometimes adhere too closely to a manuscript reading, and sometimes introduce untenable emendations. A new edition is called for, with revised collati ons of the known manuscripts, and an augmented apparatus criticus, exhibiting the large class of what I may term the ‘Vulgate’ manuscripts, which represents (...) a tradition different from, and probably later than that of our chief authority, the excellent but unfortunately incomplete eleventh-century Parisinus , which, like all primary manuscripts of this type, contains many readings or corruptions which should not on account of its mere authority be accepted slavishly. Light is often thrown on the text from less important sources, and the truth may be recovered from manuscripts of the ‘Vulgate’ family, where our better authority fails. In this connexion the study of my own manuscript has led me to some conclusions in certain passages which I venture to set forth as suggestions towards an improved constitution of the text of the Heroides. Though it is clear from the preceding investigation into its nature that O is no primary manuscript, but belongs rather to that large class which has passed through various stages of reproduction involving alterations due either to carelessness of copyists or, more rarely, to deliberate alteration, it presents at the same time a phenomenon not unusual with such manuscripts, inasmuch as it often supports the best tradition, and in some cases preserves a reading which yields the truth, or from which the truth can be elucidated. I have used the following symbols: P = Parisinus 8242 s. xi. E = Etonensis s. xi. G = Gueferbytanus s. xii. V = Schedae Vindobonenses s xii. O = my manuscript s. xiv. D = Dresdensis s. xiii. ω = all or the majonly of the ‘Vulgate’ manuscripts. ζ = some of these manuscripts. (shrink)

In my previous article on the benzene problem, I described how Pauling's valence bond (resonance) theory, sometimes regarded as a modernized version of Kekule's oscillation hypothesis, came to be accepted by chemists by the end of World War II. But the alternative molecular orbital theory, proposed by Mulliken, had already been developed and was regarded as quantitatively superior by many quantum chemists, though it was not as easy to visualize and did not seem to harmonize as well with traditional chemical (...) concepts. During the 1950s and 1960s, thanks to the efforts of Charles Coulson and many other theorists, the molecular orbital approach not only dominated theoretical discussions but also started to be accepted by the chemical community as a whole and became the preferred description for benzene. Possible reasons were: its greater calculational convenience when applied to large molecules; better expository methods directed toward chemists; the spectacular success of the Woodward-Hoffmann rules for pericyclic reactions and Fukui's frontier orbital theory; and the development of a general theory of aromaticity, which predicted properties of similar molecules such as cyclobutadiene (C4H4). The relative importance of these reasons is explored through a mail survey of chemists. (shrink)

Explores the interplay between ancient wisdom and modern cosmology Connects the philosophy of the I Ching with key recent advances in cosmology, such as the Big Bang theory, Roger Penrose's cyclic conformal cosmology, and his and Stuart Hameroff's cosmic quantum brain dynamics Explains the Taoist cosmology of Heaven-Humanity Oneness in the context of Teilhard de Chardin's evolutionism, Thomas Berry's cosmogenetic trinity, and Brian Swimme's 12 cosmological powers Examines the holographic unity of Heaven, Earth, and Humankind at microcosmic, mesocosmic, and macrocosmic (...) scales Is the universe inert and empty, or is it some way responsive to consciousness? Breathing new life into a question that has perplexed philosophers since ancient times and scientists for the last century, physicist Zhen G. Ma, Ph.D., offers a quantitative "theory of everything" that beautifully integrates ancient I Ching philosophy, Eastern Taoism, modern cosmology, and the quantum brain dynamics of consciousness. Sharing insights from his years of research on space physics and black-hole spacetime at institutions in China, Canada, and the US, complemented by studies in quantum brain dynamics and cosmological powers with Brian Swimme at the California Institute of Integral Studies, Dr. Ma explains how his integrated theory draws primarily on two key paradigms in the philosophy of cosmology and consciousness: Swimme's cosmic creation story of the universe as a green dragon and Roger Penrose and Stuart Hameroff's cosmic consciousness. Extending these theories further, Dr. Ma shows how they harmonize not only with the ancient Eastern philosophy of Heaven-Humanity Oneness, but also with a holographic cosmic principle that connects the quantum-plasma brain with the universe and the Earth with Heaven. He then looks at this holographic unity in the cyclic process of birth, growth, decay, and death and shows how it resonates with Einstein-Friedmann's cosmological dynamics and Hawking-Penrose's quantum gravity model. Demonstrating a quantitative paradigm of everything, Dr. Ma shows how humanity is inextricably and holistically blended into the cosmic fabric of the universe. (shrink)

Four well-known claims about the nature of scientific knowledge can be conjoined to challenge the traditional value-neutrality thesis. These are the Duhem-Quine thesis, the Kuhnian thesis, the "publicity of science" claim, and the "reflexivity of social inquiry" claim. Maximal objectivity reqnires not value-neutrality, but a commitment by the researcher to certain social values—namely those which tend to equalize political advantage in a community. This is an epistemological, not an ethical, argument.

Power has been studied in various guises in both the social cognition and the reasoning literatures. In this paper, three experiments are reported in which this factor was investigated in the domain of deontic thinking. Power of source of deontic statements was varied within several scenarios, and participants judged the degree to which they thought an injunction would be carried out. In the first experiment, permission statements were used, and it was found that, as predicted, power was positively related to (...) degree of endorsement of deontic conclusions across scenarios. In the second experiment, these findings were generalised across three further deontic domains (threat, warning, and promise) and two different syntactic forms (conjunctive and disjunctive). In the third experiment, the hypothesis that power effects were mediated by subjective judgements of conditional probability was investigated and confirmed. It is argued that these results favour theories that give a general role to probabilistic factors, rather than those based on domain-specific schemas. (shrink)

Cultural aspects frame our perception of the world and direct the many different ways people interact with things in it. For this reason, these aspects should be considered when designing technology with the purpose to positively impact people in a community. In this paper, we revisit the foundations of culture aiming to bring this concept in dialogue with design. To inform design with cultural aspects, we model reality in three levels of formality: informal, formal, and technical, and subscribe to a (...) systemic vision that considers the technical solution as part of a more complex social system in which people live and interact. In this paper, we instantiate this theoretical and methodological view by presenting two case studies of technology design in which culture-based artefacts were employed to inform the design process. We claim that as important as including issues related to culture in the ICT design agenda—from the conception to the development, evaluation, and adoption of a technology—is the need to support the design process with adequate artefacts that help identifying cultural aspects within communities and translating them into sociotechnical requirements. We argue that a culturally informed perspective on design can go beyond an informative analysis, and can be integrated with the theoretical and methodological framework used to support design, throughout the entire design process.

These essays offer a fascinating and lively synopsis of the work of some of the most important thinkers in Britain today. The authors represent a wide cross-section of BritainÕs current philosophical spectrum, resulting in a stimulating intellectual profile of the leaders of a community which dominated Western philosophy for much of the twentieth century. What makes a man or woman a philosopher? What are the new directions being pursued by British philosophy today? How do philosophers see their own development, and (...) what are the roots of their distinctive contributions? What are the major problems which preoccupy British philosophers today? The distinguished philosophers who have contributed to this book address these questions as well as other topics of interest. All have provided brief 'intellectual autobiographies,' including sketches of their individual concerns and how those concerns have developed throughout their careers. (shrink)

Sections 3.16 and 3.23 of Roger Penrose's Shadows of the mind (Oxford, Oxford University Press, 1994) contain a subtle and intriguing new argument against mechanism, the thesis that the human mind can be accurately modeled by a Turing machine. The argument, based on the incompleteness theorem, is designed to meet standard objections to the original Lucas-Penrose formulations. The new argument, however, seems to invoke an unrestricted truth predicate (and an unrestricted knowability predicate). If so, its premises are inconsistent. The (...) usual ways of restricting the predicates either invalidate Penrose's reasoning or require presuppositions that the mechanist can reject. (shrink)

Taking as its starting point Carr's view that historical narrative reflects the preoccupations of the time in which it is written and Foucault's concept of consensual historical discourse as the outcome of a social struggle in which the victor suppresses or at least diminishes contrary versions of historical events in favour of their own, this paper traces and discusses the historical narrative of British nursing in the Crimean war and, in particular, three competing narratives that have arisen in the latter (...) half of the 20th century and the first decade of the 21st. These are the established narrative surrounding Florence Nightingale, the new narrative surrounding Mary Seacole and an Irish narrative surrounding the role of the Sisters of Mercy. It is argued that the increased vehemence of the debate surrounding these narratives is representative of the changes that have taken place in British society. However, we also argue that the Irish narrative and its critique are reflective of deep‐rooted Anglo‐Protestant attitudes articulated by Nightingale and uncritically accepted by subsequent historians even in modern British historiography.

Background: Older, frail patients with multimorbidity are at an especially high risk for disease severity and death from COVID-19. The social restrictions proved challenging for the residents, their relatives, and the care staff. While these restrictions clearly impacted daily life in Norwegian nursing homes, knowledge about how the pandemic influenced nursing practice is sparse. Aim: The aim of the study was to illuminate ethical difficult situations experienced by Norwegian nurses working in nursing homes during the COVID-19 pandemic. Research design and (...) participants: The research design involved semistructured individual interviews conducted with 15 nurses working in 8 nursing homes in 3 health regions in Norway, within both urban and rural areas. Ethical considerations: Oral and written information about the study was provided before the participants gave their written consent. The transcribed interviews were de-identified. The study was approved by the Norwegian Centre for Research Data. Findings: Four ethical difficult situations were identified: (a) turning the nursing home into a prison; (b) using medication to maintain peace and order; (c) being left alone with the responsibility; and (d) s. impact on decision-making. Conclusions: The nurses’ ethical challenges were intertwined with external factors, such as national and local guidelines, and the nurses’ own internalized factors, which were connected to their subjective professionality. This duality inflicted emotional distress and gave nurses few opportunities to perform nursing in a professionally sound and safe manner. (shrink)

The automation of many repetitive or dangerous human activities yields numerous advantages. In order to automate a physical task that requires a finite series of sequential steps, the translation of those steps in terms of a computational procedure is often required. Even apparently menial tasks like following a cooking recipe may involve complex operations that can’t be perfectly described in formal terms. Recently, several studies have explored the possibility to model cooking recipes as a computational procedure based on a set (...) of instructions. This vision is the foundation for the construction of robotics kitchen, as Moley. These kitchen robots have shown promising results. Moley, for instance, is the very first example of a new generation of bioinspired robotics, based on the reproduction of particular movement, cooking, through artificial arms and hands. It is entirely different from the current appliances present in our domestic domain because Moley is able to manipulate ingredients and interact with kitchen equipment in order to prepare a dish autonomously. Nonetheless, they have also shown several limitations. In particular, Moley is an entirely autonomous robot in a structured environment in which it knows precisely the object position and manipulates the ingredients based on a list of instructions and a training phase made by Machine Learning. In this contribution we contend that these limitations arise from an essential mismatch between computational procedures, as originally described by Turing in his seminal 1936 paper, and recipes. Computational procedures have been originally created to observe and modify formal symbols with formal operators. Thus, they are independent from time and they are ideally executed in a closed environment, in which the computer directly produces all the relevant changes required to produce the intended result. Recipes, instead, are followed in an open environment, in which, while time goes by, changes happen independently from the cook’s intervention: the cook puts the butter on the pan, starts the fire and then waits until the butter is melted. To operate effectively in the open environment a kitchen robot must couple computational procedures with sensors, e.g a sensor which provides a time signal. These sensors are de facto oracles for the procedures and yet are required to bridge the gap from the formal to the physical world. (shrink)

The logician Kurt Godel in 1951 established a disjunctive thesis about the scope and limits of mathematical knowledge: either the mathematical mind is equivalent to a Turing machine (i.e., a computer), or there are absolutely undecidable mathematical problems. In the second half of the twentieth century, attempts have been made to arrive at a stronger conclusion. In particular, arguments have been produced by the philosopher J.R. Lucas and by the physicist and mathematician Roger Penrose that intend to show that (...) the mathematical mind is more powerful than any computer. These arguments, and counterarguments to them, have not convinced the logical and philosophical community. The reason for this is an insufficiency if rigour in the debate. The contributions in this volume move the debate forward by formulating rigorous frameworks and formally spelling out and evaluating arguments that bear on Godel's disjunction in these frameworks. The contributions in this volume have been written by world leading experts in the field. (shrink)

The article focuses on the concept of the state in the works of the German sociologist M. Weber and his contemporary, the anarchist G. Landauer. Specifically, it is commonly thought that Weber has a unique interpretation of the state, its nature, and inalienable characteristics. This Weberian approach did not fit into any of the traditions that existed at that time in Germany (for example, represented by H. Kelsen, G. Jellinek, and O. von Gierke). However, the author of the article tries (...) to demonstrate that three main Weberian aspects of the state — 1) the monopoly on legitimate physical violence, 2) the relationship of domination, which is accompanied by a minimum desire to obey, and 3) the chance for the regular reproducibility of these relationships — are consonant with Landauer’s concept of the state. This discovered conceptual affinity allows one to look at Weber’s sociology from new angles, without being impacted by the personal beliefs of the German scientist, who very critically treated anarchism as a socio-political movement. In the final section of the paper, the author discusses the modern project of “anarchist sociology”, which also uses Weberian methodology. The paper argues that “anarchist sociology” might be a promising social science with ts unique vision of several key sociological topics, such as domination, power, or social inequality. (shrink)

Roger Penrose's original and provocative ideas about the large-scale physics of the Universe, the small-scale world of quantum physics and the physics of the mind have been the subject of controversy and discussion. These ideas were set forth in his best-selling books The Emperor's New Mind and Shadows of the Mind. In this book, he summarises and brings up to date his current thinking in these complex areas. He presents a masterful summary of those areas of physics in which he (...) feels there are major unsolved problems. Through this, he introduces radically new concepts which he believes will be fruitful in understanding the workings of the brain and the nature of the human mind. These ideas are then challenged by three distinguished experts from different backgrounds - Abner Shimony and Nancy Cartwright as Philosophers of Science and Stephen Hawking as a Theoretical Physicist and Cosmologist. Finally, Roger Penrose responds to their thought-provoking criticisms. This volume provides an accessible, illuminating and stimulating introduction to Roger Penrose's vision of theoretical physics for the 21st Century. His enthusiasm, insight and good humour shine through this brilliant account of the problems of modern physics. (shrink)

Professor Sir Roger Penrose's work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. The first volume covers the beginnings of a career that is ground-breaking from the outset. Inspired by courses given by Dirac and Bondi, much of the early published (...) work involves linking general relativity with tensor systems. Among his early works is the seminal 1955 paper, 'A Generalized Inverse for Matrices', his previously unpublished PhD and St John's College Fellowship theses, and from 1967, his Adam's Prize-winning essay on the structure of space-time. Add to this his 1965 paper, 'Gravitational collapse and space-time singularities', and the 1967 paper that introduced a remarkable new theory, 'Twistor algebra', and this becomes a truly stellar procession of works on mathematics and cosmology.

In a two-tier decision-making system such as the EU Council of Ministers, if the number of constituencies (member-states) is sufficiently large (say, 15 or more), Penrose’s Square-Root rule can be implemented to a high level of approximation by a simple weighted decision rule at the top level (the Council) with any given quota q smaller than the total weight. This leaves one degree of freedom: the value of q as a free parameter, to be determined by some additional condition. (...) I propose to survey and discuss critically the most important considerations for fixing this value – some of which have actually been used by theoreticians or practitioners: efficiency, transparency, sensitivity (total voting power of citizens), mean majority deficit, giving certain ‘privileged’ coalitions blocking status. Some of these considerations are reasonably compatible; others less so. Some kind of compromise is clearly needed. But which? This is essentially a political matter; but a political decision ought to be made in a theoretically enlightened way. (shrink)

El presente artículo se propone indagar los problemas que hacen al déficit de legitimidad de lo que ha dado en llamarse la "justicia política", esto es, las respuestas judiciales frente a herencias de criminalidad política. Sugerimos que se trata de problemas estructurales que están en los límites de lo jurídico y que, por tanto, no constituyen una falla del sistema judicial en sí mismo. Con ese fin, sobre la base de los análisis realizados por Danilo Zolo y Hannah Arendt, examinamos (...) problemas estructurales en tres niveles: en la imparcialidad e independencia del tribunal, en el respeto de los principios, las normas y los procedimientos del derecho, y en el requisito de un elemento subjetivo para atribuir la responsabilidad penal de un crimen. Le propos de notre article est celui de s'interroger sur les problèmes qui produisent un déficit de légitimité en ce qu'on a appelé la " justice politique ", c'est-à-dire, les réponses judiciaires qu'on donne au legs de criminalité politique. Nous suggérons qu'il s'agit de problèmes structurels qui se situent à la limite du juridique et qui, par conséquent, ne constituent pas une faille du système juridique lui-même. Dans ce but, et sur la base des analyses réalisées par Danilo Zolo et Hannah Arendt, nous examinons trois types des problèmes : ceux qui tiennent à l'impartialité et à l'indépendance du tribunal, ceux concernant le respect des principes, normes et procédures du droit, et celui lié a l'exigence d'un élément subjectif dans l'attribution de la responsabilité pénale d'un crime.

Role congruity theory affirms that female managers face more difficulties at work because of the incongruity between female gender and leadership role expectations. Furthermore, due to this incongruity, it is harder for female managers to perceive themselves as authentic leaders. However, followers’ attributions of prototypicality could attenuate this role incongruity and have implications on a managers’ organizational identification. Hence, we expect male managers to be more authentic and to identify more with their organizations, when compared to female managers who are (...) low in prototypicality. We hypothesized that authentic leadership dimensions mediate the relation between managers’ biological gender and their OID. However, this indirect effect is conditional of these managers' team prototypicality. For testing these hypotheses, we conducted an online experiment with 149 participants from different work sectors using a 2 × 2 between-subject design. As predicted, men scored higher on authentic leadership, and three dimensions partially mediated the effect of participants’ biological gender on OID. In the low team prototypicality condition female managers scored lower in authentic leadership and identified less with the organization, whereas in the high team prototypicality condition, no gender differences were found.

This new translation of The Logic of the Cultural Sciences _ _makes Ernst Cassirer’s classic study, long out of print, available to English readers. A German Jew living in exile at the beginning of the Second World War, Cassirer wrote this book—one of his clearest and most concise—in response to the crises besetting his era. It represented to him a rethinking and completion of his magnum opus _The Philosophy of Symbolic Forms. _S. G. Lofts’s translation stays close to the original (...) German and accurately reflects the echoes of the philosophical debates of Cassirer’s day. In the book’s five linked studies, Cassirer considers the intellectual structure of the disciplines we commonly refer to as the humanities. He defines and justifies the basic philosophical perspective of the philosophy of symbolic forms, and he contributes a wealth of ideas to continuing debates about culture and what is unique in human nature.

In this paper we argue that Michael Huemer’s phenomenal conservatism—the internalist view according to which our beliefs are prima facie justified if based on how things seems or appears to us to be—doesn’t fall afoul of Michael Bergmann’s dilemma for epistemological internalism. We start by showing that the thought experiment that Bergmann adduces to conclude that is vulnerable to his dilemma misses its target. After that, we distinguish between two ways in which a mental state can contribute to the justification (...) of a belief: the direct way and the indirect way. We identify a straightforward reason for claiming that the justification contributed indirectly is subject to Bergmann’s dilemma. Then we show that the same reason doesn’t extend to the claim that the justification contributed directly is subject to Bergmann’s dilemma. As is the view that seemings or appearances contribute justification directly, we infer that Bergmann’s contention that his dilemma applies to is unmotivated. In the final part, we suggest that our line of response to Bergmann can be used to shield other types of internalist justification from Bergmann’s objection. We also propose that seeming-grounded justification can be combined with justification of one of these types to form the basis of a promising version of internalist foundationalism. (shrink)

This study aimed to understand the expressions of fear in the journeys of health professionals who worked in the confrontation of coronavirus disease 2019 (COVID‐19), in the city of Manaus, in the Brazilian Western Amazon. This is an exploratory qualitative study that adopts interpretive description as a method to generate informed knowledge responsive to the needs of the practice. We included 56 participants, comprising 23 health managers and 33 health workers (middle and higher level) of different professional categories. The results (...) revealed three circles of experience: (1) knowledge and professional experience in dealing with the disease (unknown–known–experienced); (2) the growing proximity to death and loss (predicted–witnessed–suffered); and (3) the involvement and proximity to whatever affects the individual, their emotions, and personal transformations in the face of the threat (the collective, the neighbor, and oneself). Our results suggest that health professionals who worked during the COVID‐19 pandemic in Manaus experienced insecurity, dread, and fear, illustrating the complexity of developing their activities in the front line of care and management during the different phases of the pandemic. A contribution of the study is precisely that of capturing this complexity, which suggests the impossibility of analyzing fear only in its simple manifestation, or in each circle of experience.

We examine access to institutions and opportunity for entrepreneurs in a rising tech economy. A significant proportion of entrepreneurs and CEOs of tech firms in the American economy are either first- or second-generation immigrant minorities. Are these minority entrepreneurs assimilating into a rising economic elite? To what extent is the technology economy segmented by ethnic boundaries and sectors? On a range of empirical measures, including access to financial and social capital, firm performance, and normative beliefs on fairness and cooperation, we (...) find second-generation immigrant minority tech entrepreneurs to be strikingly similar to their white counterparts. This study sheds new light on the institutional environment of a new regional technology economy, whereby barriers of entry are high in terms of human capital but economic competition is structurally and culturally open to immigrant minority entrepreneurs.

The linguistic theory of the Kabbala, as it is explained in the writings of the Kabbalists of the 13th century—or at least basically implied in them—comes to rest upon a combination of the above-mentioned interpretations of the Book of Yetsira with the doctrine of the Name of God as a basis of that language. What is essentially new in this is the way in which the scope and range of a divine language—as understood by the Kabbalists—is brought into unique prominence (...) over and beyond the realm of created man. In the Book of Yetsira there could still be some doubt as to whether the ten Sefiroth and the 22 letters were themselves thought of as created; and as we have seen, there is even considerable evidence in favor of this conception. In the doctrines and teachings of the Kabbalists, however, this is no longer the case. The ten original numbers have become ten emanations of the divine fullness of being. Where these are concerned one can only now talk in terms of creation in a meta-phorical sense. In the Sefiroth of the Kabbalists, God manifests himself in ten spheres or aspects of his activity. The 22 letters are themselves part and parcel of this area; they are configurations of the divine energies, which are themselves grounded in the world of the Sefiroth, and whose appearance in the world either beyond, outside or beneath this realm of the divine emanations is simply a gradual process of de-refinement and an intensified crystallization of those innermost signs of all things, as they correspond to the progressively evolving and increasingly condensed media of the creation. All creation, from the world of the highest angel to the lower realms of physical nature, refers symbolically to the law which operates within it—the law which governs in the world of the Sefiroth. In everything something is reflected—one might just as well say—from the realms which lie in the center of it. Everything is transparent, and in this state of transparency everything takes on a symbolic character. This means that every thing, beyond its own meaning, has something more, something which is part of that which shines into it or, as if in some devious way, that which has left its mark behind in it, forever. The Book of Yetsira was still far removed from this type of interpretation. For the Kabbalists, however, the Sefiroth and the letters, in which the word of God is explained, or which constitute the word of God, were simply two different methods in which the same reality might be represented in a symbolic manner. In other words: whether the process of the manifestation of God, his stepping outside under the symbol of the light, and his diffusion of knowledge and reflection is what is represented, or whether it is to be understood to be the activeness of the divine language, of the self-differentiating word of the creation or even of the self-explanatory name of God. In the last analysis, this, for the Kabbalists, is no more than a question of the choice between symbolic structures which are in themselves equally arranged—the symbolism of light and the symbolism of language.

Arnold J. Toynbee was not only a controversial historian, but also a beguiling internationalist. This article analyses Toynbee as an observer of international politics. In particular, it examines both his understanding of contemporary foreign politics and his constant search of a stable world order. From the idealism of his youth to the utopianism of religious origin that marked his final years, passing through his partial and temporary disenchantment with regard to his youthful expectations, this essay will follow Toynbee’s path in (...) the study of the international affairs of the Twentieth century.

The rule of rescue describes the powerful human proclivity to rescue identified endangered lives, regardless of cost or risk. Deciding whether or not to perform a decompressive craniectomy as a life-saving or ‘rescue’ procedure for a young person with a severe traumatic brain injury provides a good example of the ethical tensions that occur in these situations. Unfortunately, there comes a point when the primary brain injury is so severe that if the patient survives they are likely to remain severely (...) disabled and fully dependent. The health resource implications of this outcome are significant. By using a web-based outcome prediction model this study compares the long-term outcome and designation of two groups of patients. One group had a very severe injury as adjudged by the model and the other group a less severe injury. At 18 month follow-up there were significant differences in outcome and healthcare requirements. This raises important ethical issues when considering life-saving but non-restorative surgical intervention. The discussion about realistic outcome cannot be dichotomised into simply life or death so that the outcome for the patient must enter the equation. As in other ‘rescue situations’, the utility of the procedure cannot be rationalised on a mere cost–benefit analysis. A compromise has to be reached to determine at what point either the likely outcome would be unacceptable to the person on whom the procedure is being performed or the social utility gained from the rule of rescue intervention fails to justify the utilitarian value and justice of equitable resource allocation.

Grush and Churchland (1995) attempt to address aspects of the proposal that we have been making concerning a possible physical mechanism underlying the phenomenon of consciousness. Unfortunately, they employ arguments that are highly misleading and, in some important respects, factually incorrect. Their article ‘Gaps in Penrose’s Toilings’ is addressed specifically at the writings of one of us (Penrose), but since the particular model they attack is one put forward by both of us (Hameroff and Penrose, 1995; 1996), it is (...) appropriate that we both reply; but since our individual remarks refer to different aspects of their criticism we are commenting on their article separately. The logical arguments discussed by Grush and Churchland, and the related physics are answered in Part l by Penrose, largely by pointing out precisely where these arguments have already been treated in detail in Shadows of the Mind (Penrose, 1994). In Part 2, Hameroff replies to various points on the biological side, showing for example how they have seriously misunderstood what they refer to as ‘physiological evidence’ regarding to effects of the drug colchicine. The reply serves also to discuss aspects of our model ‘orchestrated objective reduction in brain microtubules – Orch OR’ which attempts to deal with the serious problems of consciousness more directly and completely than any previous theory.

Gödel appears to have believed strongly that the human mind cannot be explained in terms of any kind of computational physics, but he remained cautious in formulating this belief as a rigorous consequence of his incompleteness theorems. In this chapter, I discuss a modification of standard Gödel-type logical arguments, these appearing to strengthen Gödel’s conclusions, and attempt to provide a persuasive case in support of his standpoint that the actions of the mind must transcend computation. It appears that Gödel did (...) not consider the possibility that the laws of physics might themselves involve noncomputational procedures; accordingly, he found himself driven to the conclusion that mentality must lie beyond the actions of the physical brain. My own arguments, on the other hand, are from the scientific standpoint that the mind is a product of the brain’s physical activity. Accordingly, there must be something in the physical actions of the world that itself transcends computation. We do not appear to find such noncomputational action in the known laws of physics, however, so we must seek it in currently undiscovered laws going beyond presently accepted physical theory. I argue that the only plausibly relevant gap in current understanding lies in a fundamental incompleteness in quantum theory, which reveals itself only with significant mass displacements between quantum states (“Schrödinger’s cats”). I contend that the need for new physics enters when gravitational effects just begin to play a role. In a scheme developed jointly with Stuart Hameroff, this has direct relevance within neuronal microtubules, and I describe this (still speculative) scheme in the following. (shrink)

Decompressive craniectomy is a technically straightforward procedure whereby a large section of the cranium is temporarily removed in cases where the intracranial pressure is dangerously high. While its use has been described for a number of conditions, it is increasingly used in the context of severe head injury. As the use of the procedure increases, a significant number of patients may survive a severe head injury who otherwise would have died. Unfortunately some of these patients will be left severely disabled; (...) a condition likened to the RUB, an acronym for the Risk of Unacceptable Badness. Until recently it has been difficult to predict this outcome, however an accurate prediction model has been developed and this has been applied to a large cohort of patients in Western Australia. It is possible to compare the predicted outcome with the observed outcome at 18 months within this cohort. By using predicted and observed outcome data this paper considers the ethical implications in three cases of differing severity of head injury in view of the fact that it is possible to calculate the RUB for each case.

To what extent is the neural organization of language dependent on factors specific to the modalities in which language is perceived and through which it is produced? That is, is the left-hemisphere dominance for language a function of a linguistic specialization or a function of some domain-general specialization, such as temporal processing or motor planning? Investigations of the neurobiology of signed language can help answer these questions. As with spoken languages, signed languages of the deaf display complex grammatical structure but (...) are perceived and produced via radically different modalities. Thus, by mapping out the neurological similarities and differences between signed and spoken language, it is possible to identify modality-specific contributions to brain organization for language. Research to date has shown a significant degree of similarity in the neurobiology of signed and spoken languages, suggesting that the neural organization of language is largely modality-independent.

Living in cities has numerous comparative advantages than living in the countryside or in small villages and towns, most notably better access to education, services and jobs. However, it is also associated with a roughly twofold increase in some mental disorders rate incidence compared with living in rural areas. Economic assessments reported a forecasted loss of more than 19 trillion dollars in global GDP between 2011 and 2030 and of around 7 trillion for the year 2030 alone when measured by (...) the human capital method. If we exclude self-selection processes and make the hypothesis to be able to level down the mental illness rate incidence in urban areas to these of the rural by better urban-societal planning, around € 1.2 trillion could be saved yearly worldwide. Even a reduction of only 20% in urban mental illness rate would save around 250 billion dollars yearly. (shrink)
