Does natural selection act primarily on individual organisms, on groups, on genes, or on whole species? The question of levels of selection - on which biologists and philosophers have long disagreed - is central to evolutionary theory and to the philosophy of biology. Samir Okasha's comprehensive analysis gives a clear account of the philosophical issues at stake in the current debate.

What is science? Is there a real difference between science and myth? Is science objective? Can science explain everything? This Very Short Introduction provides a concise overview of the main themes of contemporary philosophy of science. Beginning with a short history of science to set the scene, Samir Okasha goes on to investigate the nature of scientific reasoning, scientific explanation, revolutions in science, and theories such as realism and anti-realism. He also looks at philosophical issues in particular sciences, including (...) the problem of classification in biology, and the nature of space and time in physics. The final chapter touches on the conflicts between science and religion, and explores whether science is ultimately a good thing. (shrink)

Resilience may be referred to as the capacity for positive adaptation and to quickly recover from difficulties and significant adversity. After examining operational definitions of related concepts, the article discusses resilience building exercises for functional fitness at the individual soldier level, to include among others, self-monitoring, self-evaluation, self-reinforcement, emotional regulation exercises, mindfulness training, relaxation and grounding exercises and importance of maintaining discipline and routine in the military. Using an acronym CARRIES, the article examines efforts to enhance resilience building through empirically (...) validated cognitive, behavioural and intrapersonal skills originating from best practices learned in the military.

Traditional accounts of belief change have been criticized for placing undue emphasis on the new belief provided as input. A recent proposal to address such issues is a framework for non-prioritized belief change based on default theories (Ghose and Goebel, 1998). A novel feature of this approach is the introduction of disbeliefs alongside beliefs which allows for a view of belief contraction as independently useful, instead of just being seen as an intermediate step in the process of belief revision. This (...) approach is, however, restrictive in assuming a linear ordering of reliability on the received inputs. In this paper, we replace the linear ordering with a preference ranking on inputs from which a total preorder on inputs can be induced. This extension brings along with it the problem of dealing with inputs of equal rank. We provide a semantic solution to this problem which contains, as a special case, AGM belief change on closed theories. (shrink)

En el presente artículo se pretende comprender el horizonte en el que la sociedad contemporánea construye su sentido de la cotidianidad, a partir de la positividad y negatividad del aburrimiento. El método empleado será la propuesta interpretativa de Heidegger, orientado por el concepto de cotidianidad en dialogo con Han, en lo referente a la manifestación del aburrimiento en la vida cotidiana de los sujetos. En una primera instancia se abordan las determinaciones de la racionalidad instrumental y el neoliberalismo en la (...) construcción de sentido en la de la sociedad contemporánea. Posteriormente, en un segundo lugar, se comprende la imposibilidad dialéctica de la positividad del aburrimiento, para luego entender cómo la negatividad del aburrimiento posibilita desde la dialéctica una negación del discurso neoliberal. Esta comprensión resulta relevante al momento de plantear la negatividad del aburrimiento como una posibilidad de mundo. Se concluye, que el aburrimiento es una apertura a los modos en los que la sociedad contemporánea construye su cotidianidad. (shrink)

Hox proteins are part of the conserved superfamily of homeodomain‐containing transcription factors and play fundamental roles in shaping animal body plans in development and evolution. However, molecular mechanisms underlying their diverse and specific biological functions remain largely enigmatic. Here, we have analyzed Hox sequences from the main evolutionary branches of the Bilateria group. We have found that four classes of Hox protein signatures exist, which together provide sufficient support to explain how different Hox proteins differ in their control and function. (...) The homeodomain and its surrounding sequences accumulate nearly all signatures, constituting an extended module where most of the information distinguishing Hox proteins is concentrated. Only a small fraction of these signatures has been investigated at the functional level, but these show that approaches relying on Hox protein alterations still have a large potential for deciphering molecular mechanisms of Hox differential control.

Défini comme l’une des parties du discours traditionnelles, l’article, « l’un des instruments odieux de notre grammaire » (Alexis François, La grammaire du purisme et l’académie française au 18ème siècle, Paris, Société Nouvelle de Librairie et d’Édition, p. 70) crée une véritable ligne de démarcation pour le phénomène langagier en tant qu’il divise les langues en deux catégories distinctes : langues avec article et langues sans article. Au-delà de la technicité grammaticale que créent le système d’article et l’absence d’article au (...) sein du groupe nominal, cette étude permet de repenser la nécessité noologique et phénoménologique de cette classe de mot bien particulière. Il convient donc de s’interroger sur l’absence d’article dans des langues avec article (français, allemand, anglais, italien, macédonien, etc.) et sur l’« absence de tout » dans des langues sans article (croate, serbe, russe, turc, etc.). Au sein des langues dépourvues de tout système d’articles, un déterminant d'origine numérale s'apparente à l'article et, ce faisant, s'approprie une valeur d'adjectif indéfini : « (un) certain ». Les deux cas de figure ou, mieux encore, les deux voies qu'empruntent les langues concernées permettent d'enrichir le tenseur binaire en psychomécanique du langage, notamment en y ajoutant des extensités médianes, non réductibles à la traditionnelle échelle « article défini » - « article indéfini » – « article zéro ».

Several authors have recently suggested that classic psychedelics might be safe and effective agents of moral enhancement. This raises the question: can we learn anything interesting about the nature of moral experience from a close examination of transformative psychedelic experiences? The interdisciplinary enterprise of philosophical psychopathology attempts to learn about the structure and function of the “ordinary” mind by studying the radically altered mind. By analogy, in this chapter we argue that we can gain knowledge about the everyday moral life (...) by studying extraordinary experiences of altered moral cognition and experience. We focus on a specific class of cases: experiences of forgiveness induced by psychedelics. We argue that close attention to such experiences reveals the importance of thought/emotion coherence and dissonance in the moral life and vindicates some heterodox ideas about moral phenomenology and psychology.

The axiom of recovery, while capturing a central intuition regarding belief change, has been the source of much controversy. We argue briefly against putative counterexamples to the axiom—while agreeing that some of their insight deserves to be preserved—and present additional recovery-like axioms in a framework that uses epistemic states, which encode preferences, as the object of revisions. This makes iterated revision possible and renders explicit the connection between iterated belief change and the axiom of recovery. We provide a representation theorem (...) that connects the semantic conditions we impose on iterated revision and our additional syntactical properties. We show interesting similarities between our framework and that of Darwiche–Pearl (Artificial Intelligence 89:1–29 1997). In particular, we show that intuitions underlying the controversial (C2) postulate are captured by the recovery axiom and our recovery-like postulates (the latter can be seen as weakenings of (C2)). We present postulates for contraction, in the same spirit as the Darwiche–Pearl postulates for revision, and provide a theorem that connects our syntactic postulates with a set of semantic conditions. Lastly, we show a connection between the contraction postulates and a generalisation of the recovery axiom. (shrink)

We propose a new relevance sensitive model for representing and revising belief structures, which relies on a notion of partial language splitting and tolerates some amount of inconsistency while retaining classical logic. The model preserves an agent's ability to answer queries in a coherent way using Belnap's four-valued logic. Axioms analogous to the AGM axioms hold for this new model. The distinction between implicit and explicit beliefs is represented and psychologically plausible, computationally tractable procedures for query answering and belief..

Waldenfelsovo fenomenološko razumijevanje moderne zasnovano je na razumijevanju stranog kao bitnog određenja moderne. Strano je ovdje odrednica mišljenja koja se eksplicira u kulturnim i društvenim odnosima te ga stoga treba interpretirati upravo u njegovom fenomenalnom realitetu. Kultura i politika u tom značenju više su od pukog imena za skupni naziv značenja i opravdanja djelovanja. One postaju izraz smisaonog konteksta u kojem se iščitava odnos spram stranog kao referentnog mjesta za razumijevanje samog značenja moderne, njene unutarnje diferenciranosti, tokova koji je određuju (...) i karakteristika koje se uspostavljaju u individualnim odrednicama što obilježavaju njenu povijest. Strano se, u cjelini svojega određenja, zasniva iz tjelesnosti kao realiteta njegovog postojanja. U cjelini uzevši, moderna se, smatra Waldenfels, razumijeva u njenoj postranjenosti , u njenom odnošenju spram stranog koje na koncu rezultira i postranjenjem moderne u cijelosti. Ona kao takva nije zastranila, nego po-stranila, i sama se priklonila stranosti kao vlastitom identitetu, u kojem je čvrsto uspostavljen i filozofijski diskurs na kojem se taj identitet brani. Odnos spram tjelesnosti, koji se postulira u modernoj teoriji, u tom smislu je konzekvenca odnosa spram stranog. Zato se problem transformacije filozofije ne nalazi u novom razumijevanju umstvenosti, nego u diskursu nove racionalnosti, fenomenološkom mišljenju partikulariteta okrenutom kritici obuhvatnosti metafizike subjektiviteta i bilo kojeg oblika umstvenih pretpostavki realiteta. Waldenfelsova interpretacija moderne proistječe iz cjelovitog uvida u kontinuitet mišljenja koje je određuje i iskazuje se kroz njegovo sažimanje u ključnim problemima koji određuju njene tokove. U tom smislu fenomenološki diskurs njegove filozofije dobiva svojevrsno značenje ishodišta filozofijskog mišljenja na prijelazu stoljeća.Waldenfels’ phenomenological understanding of modernity is based on the understanding of “the foreign” as an essential definition of modernity. “The foreign” here is the characteristic of thinking explicated in cultural and social relationships, which should therefore be interpreted precisely in its phenomenal reality. Culture and politics in this context are more then a mere names for a collection of meanings and justifications of action. They become the expression of a meaningful context from which one can read-off the relation to “the foreign” as the reference point forunderstanding the very meaning of modernity, its inner differentiation, the streams that determine it and the characteristics that are established in the individual determinants that denote its history. “The foreign” as a whole is grounded in corporality as the reality of its existence. Waldenfels maintains that modernity, taken as a whole, is understood in its orientation towards the foreign, in its relationship with the foreign that, eventually, results in the entire modernity being oriented towards the foreign. Modernity as such did not go astray, but it became oriented towards the foreign, it decided itself to accept some sort of “the foreign” as its identity, in which the philosophical discourse is established for its defence. The relationship towards corporality, postulated in this sense in modern theory, is a consequence of the relationship towards “the foreign”. That is why the problem of transformation of philosophy is not found in the new understanding of the mind, but in the discourse of new rationality, of phenomenological thinking of the particularity oriented towards the critique of the encompassing metaphysics of subjectivity and towards all sorts of rational assumptions bout the reality. Waldenfels’ interpretation of the modernity follows from the integrative insight into continuity of the thinking that determines it, and it is expressed by his summarisation of the crucial problems that determine its paths. It is in this sense that the phenomenological discourse is established, signifying the starting point of philosophical thinking at the turn of the century. (shrink)

In this paper, we extend the system AF2 in order to have the subject reduction for the $betaeta$-reduction. We prove that the types with positive quantifiers are complete for models that are stable by weak-head expansion.

Several logical puzzles, riddles and problems are defined based on the notion of games in informative contexts. Hintikka argues that epistemology or the theory of knowledge must be considered from the notion of information. So, knowledge cannot just be based on the notions of belief and justification. The present proposal will focus on the logical structure of information, and not only on the quantification of information as suggested by Claude A. Shannon. In many cases, the information bits, although seemingly or (...) factually contradictory, are quite relevant. The paraconsistent systems of logic offer a formalization of reasoning that can support certain contradictions. The well-known “Bar-Hillel–Carnap Paradox” causes embarrassment when it concludes that the informational content of a contradiction would be maximum, opposing the traditional notion that the semantic information must be true, and that contradictions are necessarily false.

We present a method for relevance sensitive non-monotonic inference from belief sequences which incorporates insights pertaining to prioritized inference and relevance sensitive, inconsistency tolerant belief revision. Our model uses a finite, logically open sequence of propositional formulas as a representation for beliefs and defines a notion of inference from maxiconsistent subsets of formulas guided by two orderings: a temporal sequencing and an ordering based on relevance relations between the putative conclusion and formulas in the sequence. The relevance relations are ternary (...) (using context as a parameter) as opposed to standard binary axiomatizations. The inference operation thus defined easily handles iterated revision by maintaining a revision history, blocks the derivation of inconsistent answers from a possibly inconsistent sequence and maintains the distinction between explicit and implicit beliefs. In doing so, it provides a finitely presented formalism and a plausible model of reasoning for automated agents. (shrink)

Here, for the first time, development studies encounters the set of ideas popularly known as 'Chaos Theory'. Samir Rihani applies to the processes of economic development, ideas from complex adaptive systems like uncertainty, complexity, and unpredictability. Rihani examines various aspects of the development process - including the World Bank, debt, and the struggle against poverty - and demonstrates the limitations of fundamentally linear thinking in an essentially non-linear world.

In this paper, we draw inferences from the Nobel laureate Amartya Sen’s book, The Idea of Justice to inform the organisational justice literature. The extant societal-level theories of justice tend to emphasise aspects that are analogous to either the procedural or distributive dimensions of organisational justice. The Senian idea of comprehensive justice is different in that it synthesises the procedural- and distributive-related dimensions at the societal-level. We theorise that the Senian notion could be applied at the organisational-level to facilitate outcomes (...) that are actually valued by the workforce. Further, we contend that the emphasis on non-parochialism in the Senian notion of justice makes it particularly relevant to the ethics of multi-national corporations operating in alien cultures. To support our contention, we analyse the lean manufacturing practices of a Japanese MNC operating in India. Our case analysis demonstrates how Senian thinking helps one surface unjust outcomes that would otherwise go unacknowledged. Our analysis also offers tentative support to Senian claims about the capacity of human behaviour to undermine well-designed institutions. Concurring with the Senian view, which favours combating manifest injustice rather than fixating over designing perfectly just institutions, we derive some normative implications to advance the cause of striving for outcomes that are actually valued by the workforce.

Bottom of the Pyramid strategies recognize for the first time that global companies can contribute to the alleviation of worldwide poverty by adopting non-traditional and mostly non-Western models of business involvement. It is now widely accepted that poverty and hunger arise not because there are no goods or food, but because billions of people lack income to purchase them. It is also a common belief that the private sector can play a significant role in lifting the poor from the margins (...) of the market system. This would require strategic and mindset shifts in global companies leading to a very different path where their operations intersect with the greater good of communities, societies, and nations. Successful engagement in the untapped market space at the base of the global income pyramid calls for completely new capabilities, responsibilities, and values. Alliance building with local and non-traditional partners, promoting bottom-up solutions and understanding social sustainability are some of these new managerial challenges. This article reflects on some of the critical challenges of global companies and global managers in their strategic engagement at the BOP and explores how large firms can become involved in the pursuit of social capital acquisition and how new approaches of public–private partnerships in reformulating the profit-performance links, the downscaling of products or services without compromising their quality and integrity, the bridging of the information and infrastructure gap, educating, and empowering the poor, together with innovations through technological adaptations can be managed through the embracing of new mindsets. A number of frameworks are presented with a view to contributing to the debate and outlining new value objectives for global companies. (shrink)

This paper overviews the role of tradition in the structure, processes and behaviour of Chinese work organ izations. The traditional value frameworks combining Confucian, Taoist and Buddhist principles and prac tices had long been the surrogate of a well-defined legal structure in China. Social interaction based on the strong guanxi bonds dominates the managerial culture and such vehicles of social capital development are prerequisites of any substantive partnership building with China. The analysis presented in this overview attempts to explore the (...) reasons for relative underdevelopment of managerial autonomy and innovation, and the predominance of collective face and networking. It is suggested that there are a number of strengths in the Chinese traditions that may be helpful in the emerging managerial transitions, while pointing out areas where breaking with the past may be necessary. This paper signals the importance of more research in Asian management to alleviate the ethnocentric basis of Western-oriented mainstream management. (shrink)

Contrairement à l’ironie polémique et insidieuse des Sophistes, celle de Socrate est plutôt interrogeante, désirante et ex-centrique, toujours en quête de connaissance vraie. Le fameux «je sais que je ne sais rien» devient chez lui un outil de défigement de la pensée prisonnière des «systèmes compacts», mais, aussi le meilleur remède contre les pseudo-vérités religieuses et idéologiques.

During the past three decades, two terms, “postmodernism” and “globalization” have entered not only academic discourse, but everyday discussions outside the groves of academia. This book contains essays assembled with a conviction that both postmodernism and globalization have the potential to be valuable tools for social analysts, this despite the uncertainties and ambiguities that persist. The editors and the contributors make no claim to have found a solution that would overcome the uncertainties and ambiguities. Rather, it is assumed that at (...) some level both the concepts will remain contested. All the essays are expressions of efforts to employ one or both of the concepts in terms of empirically grounded topics. They also add further precision or clarity to the concepts themselves in order to enhance their utility in making sense of the dynamics of social change. (shrink)

Architectural theory arises from building, when the mind considers its symbolic relations to its own constructions. The intent of this essay is to discuss the intellectual causes that precede building and precede theory. It considers certain fundamental dualities in our thinking about architecture—such as image and word; type and model; imitation and invention—and the role they play in its making, its perfection as an art, and the eventual elaboration of its tenets into a theory. At a time when theories of (...) architecture proliferate as expressions of ‘personal philosophies,’ a careful and incisive philosophical approach to if, how, and when does theory become formative of building, may ensure that architecture remain faithful to its intrinsic purposes.

Contrary to the general belief that modernist art and architecture reflect the technological society, Jacques Ellul maintains in his L’empire du non-sens that they are justifications for the integration of humankind into what he called the technicist complex. Modernism in art and architecture meant that every product must be qualified by a technological character. This unassailable belief exerted some far-reaching influences on symbolic thought, on artistic expression, on architectural character. If imitation and invention were the two inseparable concepts through which (...) art and architecture were produced and symbolized, it is because they operate on a certain transparency between an exemplar and a work of art. By contrast, in the mentality of technique, artistic production operates based on a certain opacity to meanings outside of itself. Imitation and invention were separated. Thus, one of the principal beliefs in modernism, that art and architecture symbolize the technological society is actually one of its weakest. In considering technology as both the symbol and the product, the artistic idea and its representation collapsed into each other. (shrink)

This essay assesses the opposition of pluralism and monism with respect to politics and architecture, developing the argument within three general areas: the spurious association between political intentions and architectural character, the distinctions and commonalties between political freedom and artistic freedom, and the adverse effect of inappropriate associations between political content and artistic form in general and, in particular, the perceptual impairment of the processes by which buildings come to be endowed with their suitable character.

Today, anxiety is usually thought of as a pathology, the most diagnosed and medicated of all psychological disorders. But anxiety isn't always or only a medical condition. Indeed, many philosophers argue that anxiety is a normal, even essential, part of being human, and that coming to terms with this fact is potentially transformative, allowing us to live more meaningful lives by giving us a richer understanding of ourselves. In Anxiety, Samir Chopra explores valuable insights about anxiety offered by ancient (...) and modern philosophies-Buddhism, existentialism, psychoanalysis, and critical theory. Blending memoir and philosophy, he also tells how serious anxiety has affected his own life-and how philosophy has helped him cope with it. Chopra shows that many philosophers-including the Buddha, Kierkegaard, Nietzsche, Freud, and Heidegger-view anxiety as an inevitable human response to existence: to be is to be anxious. Drawing on Karl Marx and Herbert Marcuse, Chopra examines how poverty and other material conditions can make anxiety worse, but he emphasizes that not even the rich can escape it. Nor can the medicated. Inseparable from the human condition, anxiety is indispensable for grasping it. Philosophy may not be able to cure anxiety but, by leading us to greater self-knowledge and self-acceptance, it may be able to make us less anxious about being anxious. Personal, poignant, and hopeful, Anxiety is a book for anyone who is curious about rethinking anxiety and learning why it might be a source not only of suffering but of insight. (shrink)

The “free” in “free software” refers to a cluster of four specific freedoms identified by the Free Software Definition. The first freedom, termed “Freedom Zero,” intends to protect the right of the user to deploy software in whatever fashion, towards whatever end, he or she sees fit. But software may be used to achieve ethically questionable ends. This highlights a tension in the provision of software freedoms: while the definition explicitly forbids direct restrictions on users’ freedoms, it does not address (...) other means by which software may indirectly restrict freedoms. In particular, ethically-inflected debate has featured prominently in the discussion of restrictions on digital rights management and privacy-violating code in version 3 of the GPL (GPLv3). The discussion of this proposed language revealed the spectrum of ethical positions and valuations held by members of the free software community. In our analysis, we will provide arguments for upholding Freedom Zero; we embed the problem of possible uses of software in the broader context of the uses of scientific knowledge, and go on to argue that the provision of Freedom Zero mitigates against too great a moral burden—of anticipating possible uses of software—being placed on the programmer and that, most importantly, it facilitates deliberative discourse in the free software community.

The paper presents a comprehensive survey and critique of literature on human values and ethics in business across diverse cultures. According to the author, the key issue in this discourse is not about whose values and morality, but about what values and morality. The author argues for a holistic paradigm in this discourse, grounded in deep philosophy and drawing upon the spiritual values of humanism. The consumerist, market economy Western models of ethics cannot be the only answer to values issues (...) surfacing in the wake of increasing economic globalization. The most exciting thing about international business is that it offers the opportunity to discover the human values that resonate through all cultures.1 What is more ethical—considering all nations as if they were same or accepting different standards of behaviour in different contexts?
