"La nouvelle nous est parvenue que pas une étymologie de Heidegger, pas même Léthé et Aléthès, n'était exacte. Mais le problème est-il bien posé?Tout critère scientifique d'étymologie n'a-t-il pas d'avance été répudié, au profit d'une pure et simple Poésie? On croit bon de dire qu'il n'y a là que des jeux de mots. Ne serait-il pas contradictoire d'attendre une quelconque correction linguistique d'un projet qui se propose explicitement de dépasser l'étant scientifique et technique vers l'étant poétique? Il ne s'agit pas (...) d'étymologie à proprement parler, mais d'opérer des agglutinations dans l'autre-langue, pour obtenir des surgissements dans la langue". (Gilles Deleuze Critique et clinique, 1993, p. 122 à 124). Ces lignes de Deleuze expriment parfaitement et par avance l'objection que l'on pourrait opposer à notre ouvrage. Cependant, et tout en conservant à Deleuze un respect entier pour sa belle oeuvre, nous ne pensons pas que des "agglutinations" dans la langue suffisent à faire passer dans un registre poétique. Le détail de notre démonstration philosophique et philologique a voulu montrer que Heidegger, en faisant comme s'il "entendait" la pensée grecque de l'origine, est entré dans une région que ne peuvent plus atteindre ni philosophie, ni philologie, ni même poésie, parce qu'elle se retire dans l'invérifiable.

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.

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)

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.

We investigate the upper semilattice Eq* of recursively enumerable equivalence relations modulo finite differences. Several natural subclasses are shown to be first-order definable in Eq*. Building on this we define a copy of the structure of recursively enumerable many-one degrees in Eq*, thereby showing that Th has the same computational complexity as the true first-order arithmetic.

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)

§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)

We show that the elementary theory of the recursively enumerable tt-degrees has the same computational complexity as true first-order arithmetic. As auxiliary results, we prove theorems about exact pairs and initial segments in the tt-degrees.

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.

La délicate mise en rapport de la philosophie nietzschéenne et de l’économie est d’une pratique récente. Dans ce contexte, cet article est motivé par l’introduction du traitement nietzschéen de la « destruction créatrice » en économie et la manière de justifier philosophiquement cette référence. Pour cela, nous mettons en concurrence les interprétations évolutionnistes et nietzschéennes de la destruction créatrice. Ces deux métaphores nous semblent difficilement conciliables et nous avançons des arguments en faveur de la volonté de puissance, contre la lutte (...) pour la vie, pour mieux interpréter le mécanisme de destruction créatrice.

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)

Cet article s’inscrit dans la lignée de précédents travaux visant à rapprocher l’entrepreneur schumpétérien et le surhumain nietzschéen. Les deux partagent une créativité pouvant s’interpréter comme l’extériorisation d’un surcroît de force qui, dans l’optique nietzschéenne, s’assimile à la source extra-morale de l’accroissement de la vie. Reste à savoir si le cadre dans lequel ils évoluent est le même. Au-delà d’une approche historique du cycle de la conjoncture, notre hypothèse est que l’approche philosophique d’un cycle du devenir s’avère être féconde pour (...) une interprétation enrichie du cycle de la conjoncture, complétant et prolongeant ainsi notre interprétation du surhumain et de l’entrepreneur.

We give new examples of FA presentable torsion-free abelian groups. Namely, for every n2, we construct a rank n indecomposable torsion-free abelian group which has an FA presentation. We also construct an FA presentation of the group in which every nontrivial cyclic subgroup is not FA recognizable.

We give a first-order coding without parameters of a copy of in the computably enumerable weak truth table degrees. As a tool, we develop a theory of parameter definable subsets.

Judith Andre examines the issue of the scope of the market. She offers a framework for thinking about the issue of blocked exchanges that draws upon concepts of ownership, alienation, and the impact of the market on exchanges, interactions, and market participants. She shows where Michael Walzer's notion of dominance fits into her wider taxonomy of the limits of the market.

The Jordan decomposition theorem states that every function $f \colon \, [0,1] \to \mathbb {R}$ of bounded variation can be written as the difference of two non-decreasing functions. Combining this fact with a result of Lebesgue, every function of bounded variation is differentiable almost everywhere in the sense of Lebesgue measure. We analyze the strength of these theorems in the setting of reverse mathematics. Over $\mathsf {RCA}_{0}$, a stronger version of Jordan’s result where all functions are continuous is equivalent to (...) $\mathsf {ACA}_0$, while the version stated is equivalent to ${\textsf {WKL}}_{0}$. The result that every function on $[0,1]$ of bounded variation is almost everywhere differentiable is equivalent to ${\textsf {WWKL}}_{0}$. To state this equivalence in a meaningful way, we develop a theory of Martin–Löf randomness over $\mathsf {RCA}_0$. (shrink)

Human beings respond to their immediate environments in a variety of ways, with emotion playing a cardinal role. In evolutionary theories, emotions are thought to prepare an organism for action. The interplay of acoustic environments, emotions, and evolutionary needs are currently subject to discussion in soundscape research. Universal definitions of emotion and its nature are currently missing, but there seems to be a fundamental consensus that emotions are internal, evanescent, mostly conscious, relational, manifest in different forms, and serve a purpose. (...) Research in this area is expanding, particularly in regards to the context-related, affective, and emotional processing of environmental stimuli. A number of studies present ways to determine the nature of emotions elicited by a soundscape and to measure these reliably. Yet the crucial question—which basic and complex emotions are triggered and how they relate to affective appraisal—has still not been conclusively answered. To help frame research on this topic, an overview of the theoretical background is presented that applies emotion theory to soundscape. Two latent fundamental dimensions are often found at the center of theoretical concepts of emotion: valence and arousal. These established universal dimensions can also be applied in the context of emotions that are elicited by soundscapes. Another, and perhaps more familiar, parallel is found between emotion and music. However, acoustic environments are more subtle than musical arrangements, rarely applying the compositional and artistic considerations frequently used in music. That said, the measurement of emotion in the context of soundscape studies is only of additional value if some fundamental inquiries are sufficiently answered: To what extent does the reporting act itself alter emotional responses? Are all important affective qualities consciously accessible and directly measurable by self-reports? How can emotion related to the environment be separated from affective predisposition? By means of a conceptual analysis of relevant soundscape publications, the consensus and conflicts on these fundamental questions in the light of soundscape theory are highlighted and needed research actions are framed. The overview closes with a proposed modification to an existing, standardized framework to include the meaning of emotion in the design of soundscapes. (shrink)

Recent attempts to develop and apply digital ethics principles to address the challenges of the digital transformation leave organisations with an operationalisation gap. To successfully implement such guidance, they must find ways to translate high-level ethics frameworks into practical methods and tools that match their specific workflows and needs. Here, we describe the development of a standardised risk assessment tool, the Principle-at-Risk Analysis (PaRA), as a means to close this operationalisation gap for a key level of the ethics infrastructure at (...) many organisations – the work of an interdisciplinary ethics panel. The PaRA tool serves to guide and harmonise the work of the Digital Ethics Advisory Panel at the multinational science and technology company Merck KGaA in alignment with the principles outlined in the company’s Code of Digital Ethics. We examine how such a tool can be used as part of a multifaceted approach to operationalise high-level principles at an organisational level and provide general requirements for its implementation. We showcase its application in an example case dealing with the comprehensibility of consent forms in a data-sharing context at Syntropy, a collaborative technology platform for clinical research.

Unlike other classical arguments for the existence of God, Pascal’s Wager provides a pragmatic rationale for theistic belief. Its most popular version says that it is rationally mandatory to choose a way of life that seeks to cultivate belief in God because this is the option of maximum expected utility. Despite its initial attractiveness, this long-standing argument has been subject to various criticisms by many philosophers. What is less discussed, however, is the rationality of this choice in situations where the (...) decision-makers are confronted with greater uncertainty. In this paper, I examine the imprecise version of Pascal’s Wager: those scenarios where an agent’s credence that God exists is imprecise or vague rather than precise. After introducing some technical background on imprecise probabilities, I apply five different principles for decision-making to two cases of state uncertainty. In the final part of the paper, I argue that it is not rationally permitted to include zero as the lower probability of God’s existence. Although the conditions for what makes an act uniquely optimal vary significantly across those principles, I also show how the option of wagering for God can defeat any mixed strategy under two distinct interpretations of salvation.

This article begins with Werner Herzog's programmatic statements on new images and deep truth and connects it to ideas of Nietzschean aesthetics, mainly the Apollonian image and the Dionysian horror. My main argument is that Herzog contributes to the literary and aesthetic tradition of new mythology within the medium of film by developing a distinct visual language that tries to express non-rational truth claims. In a first step I explore how Nietzschean aesthetics influenced the debates about the mythic image and (...) total cinema in classic film theory and visual studies. More importantly I show how the desire to create new mythic images not only influenced Herzog's discourse on film, but his actual aesthetic practice. In my analysis of his 1971 documentary Land of Silence and Darkness I show how the dynamic between Apollonian veil and Dionysian Urbild is effective in the construction of what Herzog calls “deep truth”.

The Fourth Industrial Revolution is a phrase that is frequently heard in the media. This study explores the major changes that this revolution has installed for us. The Fourth Industrial Revolution is an umbrella term for many aspects, and the study takes note of the concepts like the Internet of Things, artificial intelligence, artificial general intelligence, artificial superintelligence, transhumanism and Homo digitalis. The spin-off effect of this revolution may cause possible disruptive effects on Homo sapiens by creating greater numbers of (...) Homo disruptus. The term Homo disruptus is not a frequently used term, although it can be used in conjunction with the disruption that will be part of our future. Disruption may occur because of emerging technology, robotics, unemployment, digital dictatorships and exploitation, the side effects of Homo digitalis and transhumanism. The church will be part and parcel of this world, although the church does not have to be a victim and can play a significant role in anchoring Homo disruptus with the timeless message of the gospel and finding innovative ways to deal with their disruptive world.

We investigate the strength of a randomness notion ${\cal R}$ as a set-existence principle in second-order arithmetic: for each Z there is an X that is ${\cal R}$-random relative to Z. We show that the equivalence between 2-randomness and being infinitely often C-incompressible is provable in $RC{A_0}$. We verify that $RC{A_0}$ proves the basic implications among randomness notions: 2-random $\Rightarrow$ weakly 2-random $\Rightarrow$ Martin-Löf random $\Rightarrow$ computably random $\Rightarrow$ Schnorr random. Also, over $RC{A_0}$ the existence of computable randoms is equivalent (...) to the existence of Schnorr randoms. We show that the existence of balanced randoms is equivalent to the existence of Martin-Löf randoms, and we describe a sense in which this result is nearly optimal. (shrink)

We also prove that some low non-computably enumerable enumeration degree contains no set which is simple relative to $\emptyset$ '.

Résumé — En relisant l’Essay sceptique et en suivant le cours, souvent désordonné, de ses arguments, nous avons voulu marquer comment le scepticisme de Jean-Pierre Camus a opéré dans la suite de son œuvre. Dans les romans à fonction édifiante, comme dans la théologie mystique, il développe, de façon explicite ou implicite, une sorte d’anthropologie qui réduit l’illusion de maîtrise du sujet. Une théorie du singulier, de l’événement et de la situation s’oppose à la représentation d’un universel abstrait. Le thème (...) du dessaisissement du sujet et la réflexion sur les rapports entre activité et passivité accompagne, sans la subvertir, la visée apologétique et moralisatrice.— While reading the Essay sceptique and following the course of his arguments, we aim at showing how Jean-Pierre Camus’s scepticism has been at work in his future books. He’s developing, if not always officially, in his novels for edification as well as in mystical theology, a kind of anthropology which tends to lower the illusion of mastering a subject. Far from representing an abstract universal, a theory of singularity, of the event and situation opposes it. The robbing of a subject’s attributes and the reflexion on intercourses between activity and passivity comes along with an apologetic design, without undoing it. (shrink)

De acordo com BL. Hijmans, diante da pergunta sobre o caráter filosófico do pensamento de Epicteto é possível afirmar que ele não se constitua, de fato, como uma filosofia. Para Hijmans, o estoicismo epictetiano é construído a partir de um conjunto de crenças inquestionáveis que têm como base a relação de submissão a um princípio divino responsável por criar e comandar o cosmos. Por esse motivo, Hijmans afirma que faltam dois elementos ao pensamento de Epicteto para caracterizá-lo como filosofia, são (...) eles: o sentimento de maravilhamento ou perplexidade típico de uma reflexão filosófica e a capacidade de autocrítica. Nesse sentido, nosso artigo irá propor duas objeções aos argumentos de Hijmans com o intuito de demonstrar que o estoicismo de Epicteto detém as características necessárias para ser considerado, de fato, filosofia.
