“This title, I chose it because I don’t understand Hebrew and because it was very short, because it was opaque and a little unbreakable, like an atomic nucleus. For the first screening of the film at the Empire Theater, George Cravenne asked me: ‘What is the title of the film?’ ‘Shoah.’ ‘What does it mean?’ ‘I don’t know.’ ‘But how, you must translate it! No one will understand!’ And I said: ‘It’s what I want, that no one understands.’”1The common denominator (...) of any translation is delay: this delay is a matter of time and space, a temporal displacement, a delay that exacerbates the ontological differentiation process between sign and meaning.2 Between the moment..

Why translation? Doesn’t this theme seem archaic in our present day? Yes, precisely. One could say that translation is an outdated topic but it also embodies an outdated mode of historical inquiry into shifting media environments and constant reconfigurations of values, beliefs and representations.

Social constructionists maintain that we invent the properties of the world rather than discover them. Is reality constructed by our own activity? Do we collectively invent the world rather than discover it? André Kukla presents a comprehensive discussion of the philosophical issues that arise out of this debate, analysing the various strengths and weaknesses of a range of constructivist arguments and arguing that current philosophical objections to constructivism are inconclusive. However, Kukla offers and develops new objections to constructivism, distinguishing (...) between the social causes of scientific beliefs and the view that all ascertainable facts are constructed.

Social constructivists maintain that we invent the properties of the world rather than discover them. Is reality constructed by our own activity? Or, more provocatively, are scientific facts--is everything --constructed? Social Constructivism and the Philosophy of Science is a clear assessment of this critical and increasingly important debate. Andre Kukla presents a comprehensive discussion of the philosophical issues involved and analyzes the strengths and weaknesses of a range of constructivist arguments, illustrating the divide between the sociology and the philosophy of (...) science through examples as varied as laboratory science, time, and criminality. He argues that current philosophical objections to constructivism are drastically inconclusive, while offering and developing new objections. Throughout, Kukla distinguishes between the social causes of scientific beliefs and the view that all ascertainable facts are constructed. (shrink)

This book offers a superbly clear analysis of the standard arguments for and against scientific realism. In surveying claims on both sides of the debate, Kukla organizes them in ways that expose unnoticed connections. He identifies broad patterns of error, reconciles seemingly incompatible positions, and discovers unoccupied positions with the potential to influence further debate. Kukla's overall assessment is that neither the realists nor the antirealists may claim a decisive victory.

The interplay between computability and randomness has been an active area of research in recent years, reflected by ample funding in the USA, numerous workshops, and publications on the subject. The complexity and the randomness aspect of a set of natural numbers are closely related. Traditionally, computability theory is concerned with the complexity aspect. However, computability theoretic tools can also be used to introduce mathematical counterparts for the intuitive notion of randomness of a set. Recent research shows that, conversely, concepts (...) and methods originating from randomness enrich computability theory.The book covers topics such as lowness and highness properties, Kolmogorov complexity, betting strategies and higher computability. Both the basics and recent research results are desribed, providing a very readable introduction to the exciting interface of computability and randomness for graduates and researchers in computability theory, theoretical computer science, and measure theory.

The instrumentalist argument from the underdetermination of theories by data runs as follows: (1) every theory has empirically equivalent rivals; (2) the only warrant for believing one theory over another is its possession of a greater measure of empirical virtue; (3) therefore belief in any theory is arbitrary. In this paper, I examine the status of the first premise. Several arguments against the universal availability of empirically equivalent theoretical rivals are criticized, and four algorithms for producing empirically equivalent rivals are (...) defended. I conclude that the case for the first premise of the argument from underdetermination is very strong. The disposition of the argument itself depends on the fate of the second premise. (shrink)

Both sides in the debate about scientific realism have argued that their view provides a better account of actual scientific practice. For example, it has been claimed that the practice of theory conjunction presupposes realism, and that scientists' use of multiple and incompatible models presupposes some form of instrumentalism. Assuming that the practices of science are rational, these conclusions cannot both be right. I argue that neither of them is right, and that, in fact, all scientific practices are compatible with (...) both realism and instrumentalism. I also repudiate van Fraassen's argument to the effect that the instrumentalist account of scientific practice is logically weaker, hence better, than the realist account. In the end, there are no scientific practice arguments on the table that support either side of the debate. It is also noted that the deficiencies of van Fraassen's argument are recapitulated in Putnam's miracle argument for realism. My pessimistic assessment of the state of the debate is reminiscent of Arthur Fine's. However, Fine's argument for the ‘natural ontological attitude’ once again repeats the problems of van Fraassen's and Putnam's arguments. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Postmodernism:A Self-InterviewIhab HassanThe following interview did not take place in Ihab Hassan's study in Milwaukee, with a view of Lake Michigan, rippling turquoise, blue, and mauve under a sky of fluffy paratactical clouds.Interviewer: You are sometimes known as the Father...Hassan: Please! At most, the Godfather of Postmodernism, though I don't know who the Godmother is. Maybe Madam Hype?I: Why hype?H: Because postmodernism began as a genuinely contested idea and (...) is fading as a form of media hype.I: Can you define it, however tentatively?H: I would prefer not to. In fact, I cannot, no more than I can define romanticism or modernism in a sentence or paragraph. Such definitions are best left to some onomastic genius. Once, I offered a table of features contrasting modernism with postmodernism. Once is quite enough.I: Why is that?H: Because it was as widely cited as pounced upon, nearly everyone ignoring my pointed disclaimer: "Yet the dichotomies this table represents remain insecure, equivocal. For differences shift, defer, even collapse; concepts in any one vertical column are not all equivalent; and inversions and exceptions, in both modernism and postmodernism, abound."I: Well, if we can't define postmodernism, how can we talk about it? [End Page 223]H: The way we talk about everything else: say, freedom, justice, love, spirit, happiness.... We talk about postmodernism by using the word in various verbal contexts—Wittgenstein would have said "language games"—and seeing what happens.I: What happens?H: Some discussions engage postmodernism and clarify it in certain perspectives, without actually defining it: for instance, the works of Hans Bertens, Charles Jencks, Andreas Huyssen, even Fredric Jameson....I: Why even Jameson?H: Because Marxism has a tenuous relation to contemporary reality, as everyone knows except some Western academics.I: Some would say that the entire phenomenon of postmodernism is an exercise of Western academics.H: That's a bit of a non sequitur but true enough, true up to a point. Remember, the phenomenon has overflowed its theoretical origins to become a kind of ironic cultural awareness, a mode of historical reflexivity—if you wish, a perpetually anxious exercise in self-definition.I: But Western, always Western, right?H: Japan has contributed vigorously to postmodernism, especially in art and architecture. So, instead of saying "Western," let's say high-tech, mass-media, omni-consuming societies.I: That, in effect, excludes four fifths of the world, wouldn't you say?H: Yes—and no. You see, cultural postmodernism has mutated into geopolitical postmodernity. By the latter, I mean both globalization with its thousand faces (multinational capitalism, cyber technology, cultural imperialism, "Americanization"), and counter-globalization with as many masks (local knowledge, old cultural traditions, postcolonial ideologies, anti-Western resentments). It's the monster phenomenon of our time.As I have written a good deal about this phenomenon, most recently in Angelika, I won't repeat myself here. The point, however, is that postmodernity is a planetary process, postmodernism is not.I: That suggests a political dimension, which some say you have slighted in your work. How would you respond to that criticism?H: Writing in the late sixties and early seventies about postmodernism, I lacked the benefits of hindsight. For instance, I focused on high culture, Beckett and Borges and Nabokov and Barthelme and Barth. I did not foresee then that postmodernism would become a media phenomenon, involving pop and kitsch. And I recognized the emergent process of globalization only in the Seventies, in Paracriticisms (1975).But I "slighted" the political only in the sense that I did not give it [End Page 224] priority, did not make it an "absolute horizon." In fact, I believe that a primary emphasis on politics flattens, impoverishes our lives. The current paradigm in the humanities ignores the inner cost of "politics."I: Forgive me, but that's another example of what some colleagues in the profession perceive as your contrary or cross-grained character. Can you explain why politics impoverishes our lives?H: Conformists—remember Harold Rosenberg's quip about "the herd of independent minds"?—are quick to discover perversity everywhere. But never mind that. The gravamen is that politics... (shrink)

This article examines the effects on cost stickiness of firms’ involvement in corporate social responsibility activities. Cost stickiness represents asymmetric cost behavior whereby the magnitude of cost increases in response to an increase in the activity level is greater than the magnitude of cost decreases with a decrease in the activity level. We hypothesize that CSR involvement requires ongoing investments in value-creating activities; hence, it is difficult to scale down committed resources instantly even when the activity declines. We use two (...) different CSR proxies and find support for the CSR-related cost stickiness hypothesis. We further decompose CSR into strategic and tactical CSR and find that cost stickiness is more pronounced for strategic CSR. Finally, we examine the CSR-related cost behavior pattern across business cycles and find some evidence of cost stickiness during an expansionary phase of the economy and cost anti-stickiness during a recessionary phase but only for the tactical CSR component.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 25.1 (2001) 1-13 [Access article in PDF] From Postmodernism to Postmodernity: The Local/Global Context Ihab Hassan I What Was Postmodernism? What was postmodernism, and what is it still? I believe it is a revenant, the return of the irrepressible; every time we are rid of it, its ghost rises back. Like a ghost, it eludes definition. Certainly, I know less about postmodernism today than I did (...) thirty years ago, when I began to write about it. This may be because postmodernism has changed, I have changed, the world has changed.But this is only to confirm Nietzsche's insight, that if an idea has a history, it is already an interpretation, subject to future revision. What escapes interpretation and reinterpretation is a Platonic Idea or an abstract analytical concept, like a circle or a triangle. Romanticism, modernism, postmodernism, however, like humanism or realism, will shift and slide continually with time, particularly in an age of ideological conflict and media hype.All this has not prevented postmodernism from haunting the discourse of architecture, the arts, the humanities, the social and sometimes even the physical sciences; haunting not only academic but also public speech in business, politics, the media, and entertainment industries; haunting the language of private life styles like postmodern cuisine--just add a dash of raspberry vinegar. Yet no consensus obtains on what postmodernism really means.The term, let alone the concept, may thus belong to what philosophers call an essentially contested category. That is, in plainer language, if you put in a room the main discussants of the concept--say Leslie Fiedler, Charles Jencks, Jean-François Lyotard, Bernard Smith, Rosalind Krauss, Fredric Jameson, Marjorie Perloff, Linda Hutcheon and, just to [End Page 1] add to the confusion, myself--locked the room and threw away the key, no consensus would emerge between the discussants after a week. But a thin trickle of blood might appear beneath the sill.Let us not despair: though we may be unable to define or exorcise the ghost of postmodernism, we can approach it, surprising it from various angles, perhaps teasing it into a partial light. In the process, we may discover a family of words congenial to postmodernism. Here are some current uses of the term: 1. Frank Gehry's Guggenheim Museum in Bilbao (Spain), Ashton Raggatt McDougall's Storey Hall in Melbourne (Australia), and Arata Isozaki's Tsukuba Center (Japan) are considered examples of postmodern architecture. They depart from the pure angular geometries of the Bauhaus, the minimal steel and glass boxes of Mies van der Rohe, mixing aesthetic and historical elements, flirting with fragments, fantasy, and even kitsch. 2. In a recent encyclical, titled "Fideset Ratio," Pope John Paul II actually used the word postmodernism to condemn extreme relativism in values and beliefs, acute irony and skepticism toward reason, and the denial of any possibility of truth, human or divine. 3. In cultural studies, a highly politicized field, the term postmodernism is often used in opposition to postcolonialism, the former deemed historically feckless, being unpolitical or, worse, not politically correct. 4. In Pop culture, postmodernism--or PoMo as Yuppies call it insouciantly--refers to a wide range of phenomena, from Andy Warhol to Madonna, from the colossal plaster Mona Lisa I saw advertising a pachinko parlor in Tokyo to the giant, cardboard figure of Michelangelo's David--pink dayglo glasses, canary shorts, a camera slung across bare, brawny shoulders--advertising KonTiki Travel in New Zealand. What do all these have in common? Well, fragments, hybridity, relativism, play, parody, pastiche, an ironic, anti-ideological stance, an ethos bordering on kitsch and camp. So, we have begun to build a family of words applying to postmodernism; we have begun to create a context, if not a definition, for it. More impatient or ambitious readers can consult Hans Bertens' The Idea of the Postmodern, the best and fairest [End Page 2] introduction I know to the topic. But now I must make my second move or feint to approach postmodernism from a different perspective. II Postmodernism/Posmodernity. I make this move by... (shrink)

Moral reasoning typically informs environmental decision-making by measuring the possible outcomes of policies or actions in light of a preferred ethical theory. This method is subject to many problems. Environmental pragmatism tries to overcome them, but it suffers also from some pitfalls. This paper proposes a new method of environmental pragmatism that avoids the problems of both the traditional method of environmental moral reasoning and of the general versions of environmental pragmatism. We call it 'justificatory moral pluralism' - it develops (...) the intuition that normative ethical theories need not be mutually exclusive. This leaves room for important forms of pluralist environmental ethics that do not require a once-and-for-all prior commitment to an ethical theory when deciding about policies or courses of action related to the protection of the environment. Justificatory moral pluralism offers a viable solution to the recurrent conflicts between efficient environmental decisions and the need for moral reasoning. (shrink)

The Antecedent-Behavior-Consequence (ABC)-analysis is a tool for analyzing behavior and stems from the field of psychology where it is used as a tool for the understanding of behavior in general and organizational behavior in particular. In this paper the ABC-analysis is implemented as a tool to understand why people behave ethically in organizations, through the identification of key environmental factors that cause such behavior. This analysis can be the first step to recognizing the complexity of circumstances determining ethical behavior, as (...) well as trigger for changing that behavior. This will be elaborated in the implementation process of an ethical code. The working of the ABC-analysis will be illustrated with an example derived from field research concerning the reorganization of a department of a chemical company. (shrink)

More and more organisations formulate a code of conduct in order to stimulate responsible behaviour among their members. Much time and energy is usually spent fixing the content of the code but many organisations get stuck in the challenge of implementing and maintaining the code. The code then turns into nothing else than the notorious "paper in the drawer", without achieving its aims. The challenge of implementation is to utilize the dynamics which have emerged from the formulation of the code. (...) This will support a continuous process of reflection on the central values and standards contained in the code. This paper presents an assessment method, based on the EFQM model, which intends to support this implementation process. (shrink)

Presenting a fascinating analysis of the idea of what can't be said, this book ascertains whether the notion of there being a truth, or a state of affairs, or knowledge that can't be expressed linguistically is a coherent notion.

Part two evaluates two families of arguments regarding whether ineffable states of (...) affairs actually exist: the argument from mysticism and the argument from epistemic boundedness. Part three looks more closely at the relation between mystic and non-mystic stances. In the fourth and final part the author distinguishes five qualitatively different types of ineffability. _Ineffability and Philosophy_ is a significant contribution to this area of research and will be essential reading for philosophers and those researching and studying the philosophy of language.

The problem of scientific disregard is the problem of accounting for why some putative theories that appear to be well-supported by empirical evidence nevertheless play no role in the scientific enterprise. Laudan and Leplin suggest (and Hoefer and Rosenberg concur) that at least some of these putative theories fail to be genuine theoretical rivals because they lack some non-empirical property of theoreticity. This solution also supports their repudiation of the thesis of underdetermination. I argue that the attempt to provide criteria (...) of theoreticity fails, that there is a Bayesian solution to the problem of scientific disregard that fares better, and that this successful solution supports a distinctively Bayesian version of the underdetermination thesis.

Forster and Sober present a solution to the curve-fitting problem based on Akaike's Theorem. Their analysis shows that the curve with the best epistemic credentials need not always be the curve that most closely fits the data.

The antirealist argument from the underdetermination of theories by data relies on the premise that the empirical content of a theory is the only determinant of its belief-worthiness (premise NN). Several authors have claimed that the antirealist cannot endorse NN, on pain of internal inconsistency. I concede this point. Nevertheless, this refutation of the underdetermination argument fails because there are weaker substitutes for NN that will serve just as well as a premise to the argument. On the other hand, antirealists (...) have not made a convincing casefor NN (or its weaker substitutes) either. In particular, I criticize van Fraassen's recent claim that all ampliative rules in epistemology must be rejected on the grounds that they lead to incoherence. The status of the underdetermination argument remains unsettled. (shrink)

Scientific realists have argued that the truth(likeness) of our theories provides the only explanation for the success of science. I consider alternative explanations proposed by antirealists. I endorse Leplin's contention that neither van Fraassen's Darwinist explanation nor Laudan's methodological explanation provides the sort of explanatory alternative which is called for in this debate. Fine's suggestion--that the empirical adequacy of our theories already explains their success--is more promising for antirealists. Leplin claims that this putative explanation collapses into realism on one reading (...) and into vacuity on another reading. But his analysis conflates three doctrines into two, and one of the three avoids both realism and vacuity. (shrink)

Why do organizations need to learn? This question will be discussed in this article, as well as the definition and characteristics of learning organizations. The reader will get a comprehensive description of a learning organization based on Peter M.

The final chapter will get an outlook that future learning processes within networks will have a stronger role, since it allows a better understanding between intraorganizational and interorganizational (...) learning processes. Purpose of the article: This article will lead you within the topic of learning organizations. It will set a first input to different approaches how a learning organization can be defined and get established.Through this the reader will get an impression that a common vision is very important for these approches. So this article will set a first trigger for the interested reader for learning organisazations. Methodology/methods: Literature study for creation of new knowledge due to scientific work.Scientific aim: The reader will get a comprehensive description of a learning organization based on Peter M. Senge “The fifth discipline” to understand how a learning organization differs from traditional organizations due to literatur study. The article will show that there is still a lot of research potential to create a role model concept for the implementation of a learning organizsation. Findings: Due to the inconsistent research results further multifaceted approaches remain to gather further research results. As more people will be employed in organizations, communication will become a more important component within a learning organization. Furher more a common vision is very important to establish a learning organization. Conclusions : Core issue lies in questioning how learning processes of individuals and within organizations are working. The various concepts for “learning organization” describing organizational learning, to constantly expand the learning ability of organizations and, consequently, the skills to solve problems from individuals and organizations itself. Here the integrative approaches e.g. the fifth discipline try to close the research gap and clarify the phenomenon of organizational learning.. Due to the inconsistent research results further multifaceted approaches remain to gather further research results. As more people will be employed in organizations, communication will become a more important component within a learning organization.. Different approaches showed the importance of communication within learning organizations as a fundamental component of those. Following the results of these concepts, it is important to promote collective learning processes so that organizational learning can occur.. In future learning within networks will get a more and more important role, as it allows to forster the understanding between intraorganisational and interorganizational learning processes..

The biinterpretability conjecture for the r.e. degrees asks whether, for each sufficiently large k, the [Formula: see text] relations on the r.e. degrees are uniformly definable from parameters. We solve a weaker version: for each k ≥ 7, the [Formula: see text] relations bounded from below by a nonzero degree are uniformly definable. As applications, we show that Low 1 is parameter definable, and we provide methods that lead to a new example of a ∅-definable ideal. Moreover, we prove that (...) automorphisms restricted to intervals [d, 1], d ≠ 0, are [Formula: see text]. We also show that, for each c ≠ 0, can be interpreted in [0, c] without parameters.

In _The Immaterial_,_ _French social philosopher André Gorz argues, in his finely-tuned and polemical style, that the economic boom that accelerated in the 1990s and crashed so spectacularly in 2008 was based largely on an immaterial consumption of symbols and ideas, as capitalism tried to overcome the crisis of the formally industrial regime by throwing itself into a new, so-called knowledge economy. In this, the last full-length theoretical work Gorz completed before his death, he argues instead for the creation (...) of a true knowledge economy. This economy would be based on zero-cost exchange and pooled resources, and knowledge would be treated as humanity’s common property. Currently, in order to exploit knowledge and turn it into capital, the capitalist enterprise privatizes specialized knowledge and claims ownership through private licenses and copyright. But as Gorz shows, the traditional foundations of such capitalist economics have begun to crumble because of the immaterial nature of this new form of product, which makes it almost impossible to measure in monetary terms. The knowledge economy, Gorz declares, _is_ the crisis of capitalism. Thought-provoking and divisive, _The Immaterial _is the perfect book for our time, as we begin to reimagine the structures of our economic system in order to rebuild and move forward. “It is to Gorz... that readers should turn for a compelling combination of sharp analysis, well-wrought polemic, and suggestions for the future.”—_Red Pepper_ “A great figure of the intellectual Left.”—Nicolas Sarkozy “Gorz’s intelligence strikes you at the very first glance: it is one of the nimblest, acutest intelligences I know.”—Jean-Paul Sartre.

Most professionals have the arduous task of managing their own dual loyalty: in one contextual relationship, they are members of a profession while simultaneously they are employed as members of a locally established organisation. This sense of a dual loyalty has to be taken into account when professional bureaucracies develop ethics programmes. This article focuses on universities. Accounting for the dual loyalty of academic professionals, it is the objective of the study to contribute to the most appropriate ethics programmes in (...) such an academic context. Based on a review of the literature, we identify which ethical issues commonly emerge in educational and research activities. Then we offer a conceptual analysis of the conditions required for each different strategy of ethics management. We argue that none of the four theoretically derived strategies is applicable solely on its own. For universities it is most promising to design ethics programmes based on the guiding values of the academic community, including integrity measures for universities and corrective measures for students. The argument developed in this article is assumed to be widely applicable in assessing the appropriateness of ethics management strategies in other professional settings. (shrink)

The aim of this book is not to impart a substantive knowledge of core psychological theories, or even to analyze critically selected theories. Instead, it is to prepare the reader to analyze and advance the theoretical literature in any tradition. Theoretical psychology stands in the same relation to psychology as theoretical physics does to physics. The traditional way to study theoretical psychology is to take up one approach after another--behavioral, psychoanalytic, cognitive, and so on. The aim of this book is (...) not to impart a substantive knowledge of core psychological theories, or even to analyze critically selected theories. Instead, it is to prepare the reader to analyze and advance the theoretical literature in any tradition. A good theoretician should be able to contribute to the study of psychoanalytic theory as readily as to behavioral theory. The skills required are the same. Instead of covering a sequence of theories, therefore, the book is organized around types of theoretical activities. It is not a work in theoretical psychology; it is a book about theoretical psychology. It also confronts psychologists' underestimation of the variety and the significance of theoretical work. Many theoretical issues do not call for empirical research--they require nothing but thinking. (shrink)

§1. Introduction. Natural sets that can be enumerated by a computable function always seem to be either actually computable or of the same complexity as the Halting Problem, the complete r.e. set K. The obvious question, first posed in Post [1944] and since then called Post's Problem is then just whether there are r.e. sets which are neither computable nor complete, i.e., neither recursive nor of the same Turing degree as K?Let be the r.e. degrees, i.e., the r.e. sets modulo (...) the equivalence relation of equicomputable with the partial order induced by Turing computability. This structure is a partial order with least element 0, the degree of the computable sets, and greatest element 1 or 0′, the degree of K. Post's problem then asks if there are any other elements of.The solution of Post's problem by Friedberg [1957] and Muchnik [1956] was followed by various algebraic or order theoretic results that were interpreted as saying that the structure was in some way well behaved:Theorem 1.1. Every countable partial ordering or even uppersemilattice can be embedded into.Theorem 1.2. For every nonrecursive r.e. degreeathere are r.e. degreesb, c < asuch thatb ∨ c = a.Theorem 1.3. For every pair of nonrecursive r.e. degreesa < bthere is an r.e. degreecsuch thata < c < b. (shrink)

Effective infectious disease control may require states to restrict the liberty of individuals. Since preventing harm to others is almost universally accepted as a legitimate (prima facie) reason for restricting the liberty of individuals, it seems plausible to employ a mid‐level harm principle in infectious disease control. Moral practices like infectious disease control support – or even require – a certain level of theory‐modesty. However, employing a mid‐level harm principle in infectious disease control faces at least three problems. First, it (...) is unclear what we gain by attaining convergence on a specific formulation of the harm principle. Likely candidates for convergence, a harm principle aimed at preventing harmful conduct, supplemented by considerations of effectiveness and always choosing the least intrusive means still leave ample room for normative disagreement. Second, while mid‐level principles are sometimes put forward in response to the problem of normative theories attaching different weight to moral principles, employing a mid‐level harm principle completely leaves open how to determine what weight to attach to it in application. Third, there appears to be a trade‐off between attaining convergence and finding a formulation of the harm principle that can justify liberty‐restrictions in all situations of contagion, including interventions that are commonly allowed. These are not reasons to abandon mid‐level theorizing altogether. But there is no reason to be too theory‐modest in applied ethics. Morally justifying e.g. if a liberty‐restriction in infectious disease control is proportional to the aim of harm‐prevention, promptly requires moving beyond the mid‐level harm principle. (shrink)

Pierre André,Michel Bourban | : Dans un contexte d’urgence, les philosophes ne peuvent plus se contenter d’élaborer des théories idéales de la justice climatique fondées sur des motivations purement morales. Il est désormais nécessaire d’envisager des approches non idéales. Nous proposons ici de prendre au sérieux le problème de la motivation à l’action et nous mettons en avant certains motifs prudentiels pour lutter contre le changement climatique, en vue non pas de remplacer, mais de renforcer les motivations morales existantes, (...) mais insuffisantes. Nous commençons par présenter trois grandes approches idéales qui ont prévalu jusqu’ici dans la recherche sur la justice climatique et sont fondées respectivement sur l’éthique déontologique, sur l’éthique des vertus et sur l’utilitarisme. Nous mettons en évidence leurs limites pratiques, en ciblant le problème de la motivation à l’action. Nous proposons ensuite quelques pistes pour résoudre ce problème en esquissant une approche non idéale de la justice climatique. Cette approche est centrée sur les motivations amorales ressortant de l’examen attentif des perturbations systémiques globales et des contextes nationaux et locaux spécifiques. Elle est à notre sens incontournable pour motiver les États-nations, les entreprises et les individus. Il s’agit cependant moins de la substituer totalement aux théories idéales de la justice climatique que de compléter celles-ci pour établir une vision plus compréhensive qui distingue le problème de la justification morale de celui de la motivation. | : In a situation of urgency, philosophers can no longer rely exclusively on ideal theories of climate justice grounded on purely moral motives. It has become necessary to build nonideal approaches. We propose to give serious consideration to the problem of motivation to act by putting forward some prudential reasons for tackling climate change—with the aim not of replacing existing but inadequate moral motivations, but of strengthening them. First, we identify three major ideal approaches that have so far prevailed in climate justice research, grounded respectively on deontological ethics, on virtue ethics, and on utilitarianism. We highlight their practical limitations, particularly with regards to the problem of motivation to act. Second, we open the way for an alternative nonideal approach to climate justice based on amoral motivations issuing from a careful examination of global systemic disruptions as well as of specific national and local situations. This approach cannot be ignored if one wishes to motivate nation-states, corporations, and individuals to act. However, our goal is not to replace ideal theory with nonideal theory, but rather to complete the former with the latter for a more comprehensive account of climate justice that distinguishes the problem of moral justification from the problem of motivation.

We use Demuth randomness to study strong lowness properties of computably enumerable sets, and sometimes of Δ20 sets. A set A⊆N is called a base for Demuth randomness if some set Y Turing above A is Demuth random relative to A. We show that there is an incomputable, computably enumerable base for Demuth randomness, and that each base for Demuth randomness is strongly jump-traceable. We obtain new proofs that each computably enumerable set below all superlow Martin-Löf random sets is strongly (...) jump traceable, using Demuth tests. The sets Turing below each ω2-computably approximable Martin-Löf random set form a proper subclass of the bases for Demuth randomness, and hence of the strongly jump traceable sets. The c.e. sets Turing below each ω2-computably approximable Martin-Löf random set satisfy a new, very strong combinatorial lowness property called ω-traceability. (shrink)
