Les Grecs anciens n'ont pas unifié l'idée de civilisation en un concept ni sous un mot uniques. Envisagée comme un processus depuis les origines, elle se présente comme une série d'acquisitions ou de pertes au terme desquelles s'est forgée une condition humaine fortement ambivalente. Conçue comme un état, elle se rencontre à l'intersection de trois axes: celui d'un régime et d'une éducation qui apprivoisent la nature; celui d'un régime politique respectueux de la loi; celui d'une politique extérieure respectueuse de la (...) justice. Mais en grec, régime politique et hégémonie portent le même nom (archê). En naturalisant et en légitimant la domination romaine Denys d'Halicarnasse en fait une force de civilisation. (shrink)

L’article adopte un point de vue unitaire selon lequel sont interrogés à la fois les témoignages sur la physique d’Antiphon, les fragments du Peri aletheias, ainsi que les plaidoyers et, parmi les œuvres qu’on a longtemps considérées comme « morales », le Peri homonoias. Une analyse détaillée d’Aristote, Physique II, 193a10‑27, et de ses commentateurs anciens, ainsi que du Peri Aletheias (F44a Pendrick, col. II, 23‑30) sert de point de départ à une mise à l’épreuve ultérieure de la thèse par (...) la lecture suivie de l’ensemble. Il s’agit de soutenir qu’Antiphon affirme et montre la superposition nécessaire du nomos sur la physis en établissant leur inégal statut ontologique, de substrat matériel d’une part, de forme accidentelle surajoutée d’autre part. Cette interprétation trouve son prolongement dans l’analyse des deux xympheronta (celui de la nature et celui de la norme), et de l’heautos qui leur est couramment associé comme le « soi-même » le serait à « l’utile », selon l’idée qu’il serait question de combattre la norme au nom de l’intérêt personnel supposé, quant à lui, naturel. Le xympheron est plutôt pris ici comme « ce qui constitue », en anthropos, si c’est selon la nature ; en membre d’une communauté politique, si c’est selon la norme. La dépendance mutuelle de la physis et du nomos, comme de leurs xympheronta respectifs, fait alors que le naturel ne se révèle qu’à l’occasion de circonstances accidentelles et éphémères qui, un moment, isolent un membre d’un groupe politique de ce groupe-là, ou au prix d’une opération intellectuelle qui, pour un temps également, fait abstraction de l’œuvre constituante du nomos.

Les historiens grecs se sont préoccupés des actions (praxeis) humaines dans l’ordre politique et militaire. Pourtant, la conception qu’ils se font de la justice (dikè, dikaion) – à laquelle ils rapportent plus ou moins directement l’ordre du monde et le cours des choses – comme d’un mécanisme de stricte rétribution et de rétablissement des équilibres rompus; leurs définitions de la nature humaine qui permettent de verser tout débordement au compte de ce qui n’est plus totalement ou plus du tout humain; (...) enfin, la manière dont ils construisent leur autorité d ‘historien : non par l’établissement critique des faits, mais grâce à l’identification de leur point de vue avec celui de la puissance de justice organisatrice du monde, sont autant d’obstacles à une problématisation éthique de l’action. Les notions d’équité, de bienveillance à l’égard des êtres humains, de mesure, de pitié interviennent bien dans leurs jugements, mais finissent toujours par se mouler dans le cadre de pensée dominant de la justice rétributive.

Nous nous sommes proposés ici de montrer qu’Aristote caractérise le fou (μαινόμενος) dans le cadre d’un système différencié d’autres notions, sans en faire seulement un cas limite, quasiment impensé. Le point de départ de l’étude est l’analyse de la triade ἀκούσιον/δι᾽ ἄγνοιαν/ἀγνοῶν qui convoque aux côtés du fou : l’homme en colère, l’homme pris de vin, celui qui dort, le méchant (μοχθηρός), l’intempérant/incontinent (ἀκρατής), le malade. Cela implique de déterminer les types d’ignorance en cause dans les actes accomplis dans chaque (...) cas et, a contrario, en contraste avec la position socratique, les différentes formes de «l’être dans le savoir» : le savoir en entéléchie première et le savoir en acte ; le savoir du général et celui du particulier ; le savoir en acte sans intervention des affections (πάθη) et le savoir avec affections. Dans l’ensemble des catégories d’acteurs envisagées qui, selon les cas ne mettent pas en acte leur savoir de la différence entre le bien et le mal temporairement, ou le font durablement au point de transformer leur ignorance un état stable (ἕξις) de méchanceté ou encore par choix, comme l’acratique, dans cet ensemble donc, le fou apparaît comme celui qui agit par ignorance (δι᾽ ἄγνοιαν) et non pas de l’un ou de l’autre des paramètres d’une action particulière, mais de tous, à l’exception d’un seul : l’agent car, dit Aristote, «comment s’ignorer soi-même» (ἑαυτόν). Un autre moment de l’article consiste à analyser ce qu’est le soi-même en question et conclut à la réduction de l’αὐτός à ce qui accompagne la mise en acte de l’existence (τὸ εἶναι) que ce soit dans l’agir (πραττειν), le faire (ποιεῖν) ou le vivre (ζῆν). Le fou, en agissant, activerait simplement son sentiment d’exister et en cela ne pourrait «s’ignorer lui-même». Mais il faudra qu’il sorte de cette position et que, revenu à la connaissance de tous les paramètres d’un acte, il se repente de ce qu’il a accompli, pour avoir droit à la qualification d’ἀκούσιος («qui a agi contre son gré»). Chez Aristote la folie semble donc ne pouvoir être philosophiquement prise en compte que comme une crise dont on sort pour mettre en acte son savoir des paramètres d’une action particulière et n’est pas excusable parce que le fou «n’aurait pas eu conscience de son acte» mais parce qu’il a retrouvé la connaissance de ce qui compose un acte.

After a quick overview on the specification of the causal role of the powers or faculties (δυνάμεις) in nutrition, from the Hippocratic physicians to Galen, via Aristotle, the article defines the set of questions about this process that the Hippocratic physicians leave open. It then examines how Aristotle provides some sort of indirect physical and ethical answers, while Galen openly takes the side of reappropriating the central Stoic concept of oikeiôsis in a Platonist way.

Considerable hope surrounds the use of disease‐specific pluripotent stem cells to generate models of human disease allowing exploration of pathological mechanisms and search for new treatments. Disease‐specific human embryonic stem cells were the first to provide a useful source for studying certain disease states. The recent demonstration that human somatic cells, derived from readily accessible tissue such as skin or blood, can be converted to embryonic‐like induced pluripotent stem cells (hiPSCs) has opened new perspectives for modelling and understanding a larger (...) number of human pathologies. In this review, we examine the opportunities and challenges for the use of disease‐specific pluripotent stem cells in disease modelling and drug screening. Progress in these areas will substantially accelerate effective application of disease‐specific human pluripotent stem cells for drug screening. (shrink)

We distinguish dynamical and statistical interpretations of evolutionary theory. We argue that only the statistical interpretation preserves the presumed relation between natural selection and drift. On these grounds we claim that the dynamical conception of evolutionary theory as a theory of forces is mistaken. Selection and drift are not forces. Nor do selection and drift explanations appeal to the (sub-population-level) causes of population level change. Instead they explain by appeal to the statistical structure of populations. We briefly discuss the implications (...) of the statistical interpretation of selection for various debates within the philosophy of biologythe `explananda of selection' debate and the `units of selection' debate. (shrink)

Over the past fifteen years there has been a considerable amount of debate concerning what theoretical population dynamic models tell us about the nature of natural selection and drift. On the causal interpretation, these models describe the causes of population change. On the statistical interpretation, the models of population dynamics models specify statistical parameters that explain, predict, and quantify changes in population structure, without identifying the causes of those changes. Selection and drift are part of a statistical description of population (...) change; they are not discrete, apportionable causes. Our objective here is to provide a definitive statement of the statistical position, so as to allay some confusions in the current literature. We outline four commitments that are central to statisticalism. They are: 1. Natural Selection is a higher order effect; 2. Trait fitness is primitive; 3. Modern Synthesis (MS)-models are substrate neutral; 4. MS-selection and drift are model-relative. (shrink)

There are two competing interpretations of the modern synthesis theory of evolution: the dynamical (also know as ‘traditional’) and the statistical. The dynamical interpretation maintains that explanations offered under the auspices of the modern synthesis theory articulate the causes of evolution. It interprets selection and drift as causes of population change. The statistical interpretation holds that modern synthesis explanations merely cite the statistical structure of populations. This paper offers a defense of statisticalism. It argues that a change in trait frequencies (...) in a population can be attributed only to selection or drift against the background of a particular statistical description of the population. The traditionalist supposition that selection and drift are description‐independent causes of population change leads the dynamical interpretation into a dilemma: it must face a contradiction or accept the loss of explanatory power.

In evolutionary biology changes in population structure are explained by citing trait fitness distribution. I distinguish three interpretations of fitness explanations—the Two‐Factor Model, the Single‐Factor Model, and the Statistical Interpretation—and argue for the last of these. These interpretations differ in their degrees of causal commitment. The first two hold that trait fitness distribution causes population change. Trait fitness explanations, according to these interpretations, are causal explanations. The last maintains that trait fitness distribution correlates with population change but does not cause (...) it. My defense of the Statistical Interpretation relies on a distinctive feature of causation. Causes conform to the Sure Thing Principle. Trait fitness distributions, I argue, do not. *Received July 2009; revised October 2009. †To contact the author, please write to: Department of Philosophy/Institute for the History, Philosophy of Science and Technology, University of Toronto, Victoria College, 91 Charles Street West, Toronto, ON M5S 1K7, Canada; e‐mail: denis[email protected].

According to Aristotelian essentialism, the nature of an organism is constituted of a particular goal-directed disposition to produce an organism typical of its kind. This paper argues—against the prevailing orthodoxy—that essentialism of this sort is indispensable to evolutionary biology. The most powerful anti-essentialist arguments purport to show that the natures of organisms play no explanatory role in modern synthesis biology. I argue that recent evolutionary developmental biology provides compelling evidence to the contrary. Developmental biology shows that one must appeal to (...) the capacities of organisms to explain what makes adaptive evolution adaptive. Moreover, the specific capacities in question are precisely those that, according to Aristotle, constitute the nature of an organism.

There are two general approaches to characterising biological functions. One originates with Cummins. According to this approach, the function of a part of a system is just its causal contribution to some specified activity of the system. Call this the ‘C-function’ concept. The other approach ties the function of a trait to some aspect of its evolutionary significance. Call this the ‘E-function’ concept. According to the latter view, a trait's function is determined by the forces of natural selection. The C-function (...) and E-function concepts are clearly quite different, but there is an important relation between them which heretofore has gone unnoticed. The purpose of this paper is to outline that relation.This is not the first paper to discuss the relation of C-function and E-function. Previous attempts all follow either one of two strategies. The first proposes that the two concepts are ‘unified.’ The other proposes that they are radically distinct and apply to wholly different fields within biology. (shrink)

The concept of the environment appears to be indispensably involved in adaptive explanation. Quite what its role is, however, is a matter of some dispute. The environment is customarily viewed as the dual of the organism; a wholly external, discrete, autonomous cause of evolution. On this view, the external environment is the principal cause of the adaptedness of form, and the determinant of what it is to be an adaptation. I argue that this conception of the environment neither adequately explains (...) nor individuates evolutionary adaptations. Instead, adaptation, properly construed, is an evolutionary response to affordances. The environment, traditionally construed, underdetermines an organism’s affordances. Instead, I argue that the environment takes its place in evolutionary models not as a discrete causal entity, but as an abstraction. (shrink)

According to a prominent view of evolutionary theory, natural selection and the processes of development compete for explanatory relevance. Natural selection theory explains the evolution of biological form insofar as it is adaptive. Development is relevant to the explanation of form only insofar as it constrains the adaptation-promoting effects of selection. I argue that this view of evolutionary theory is erroneous. I outline an alternative, according to which natural selection explains adaptive evolution by appeal to the statistical structure of populations, (...) and development explains the causes of adaptive evolution at the level of individuals. Only together can a statistical theory of selection and a mechanical theory of development explain why populations of organisms comprise individuals that are adapted to their conditions of existence.

The Art Instinct reveals that it is, combining evolutionary psychology with aesthetics to shed new light on fascinating questions about the nature of art.

This paper comprises a case study illustrating ethical and practical challenges for a Ugandan hospital-based social worker early in the COVID-19 pandemic, followed by a commentary. The hospital was under-resourced, with staff and patients experiencing lack of information and panic. The social worker, Denis Adia, recounts his responses to new and ethically challenging situations, including persuading Muslim patients to stop fasting for the good of their health; deciding to keep a baby in hospital with parents although this was against (...) the rules; and supporting a stigmatised former patient in the face of intimidation by colleagues. He reflects on the importance of recognising each person’s unique needs and circumstances, seeing this as a vital role for social workers. The case is followed by a commentary from a UK academic (Sarah Banks), who notes the cognitive and emotional effort (‘ethics work’) undertaken by the social worker to: see the ethical aspects of particular situations; take account of patients’ specific needs; ensure they are treated with respect; promote their well-being; and perform as a good social worker. Banks draws attention to the key role of the virtue of courage in pandemic conditions, which involves working with new risks and facing fears with confidence. (shrink)

What is Life? This is the question asked by Denis Noble in this very personal and at times deeply lyrical book. Noble is a renowned physiologist and systems biologist, and he argues that the genome is not life itself: to understand what life is, we must view it at a variety of different levels, all interacting with each other in a complex web. It is that emergent web, full of feedback between levels, from the gene to the wider environment, (...) that is life. (shrink)

Is an appropriate causal connection to the past experience it represents a necessary condition for a mental state to qualify as an episodic memory? For some years this issue has been the subject of an intense debate between the causalist theory of episodic memory (CTM) and the simulationist theory of episodic memory (STM). This paper aims at exploring the prospects for an embodied approach to episodic memory and assessing the potential case for causalism that could be founded on it. In (...) a critical section, it argues that the empirical data to which STM appeals are both incomplete and inconclusive, and on closer examination even provide support for a proceduralist version of CTM. In a constructive section, it elaborates on the notion of a necessary causal connection in terms of particular procedural patterns acquired at encoding and operative at retrieval, grounding this move on recent empirical data about eye movements in mnemonic mental imagery.

The need to create art is found in every human society, manifest in many different ways across many different cultures. Is this universal need rooted in our evolutionary past? The Art Instinct reveals that it is, combining evolutionary psychology with aesthetics to shed new light on fascinating questions about the nature of art.

What is Life? To answer this question, Denis Noble argues that we must look beyond the gene's eye view. For modern 'systems biology' considers life on a variety of levels, as an intricate web of feedback between gene, cell, organ, body, and environment. He shows how it is both a biologically rigorous and richly rewarding way of understanding life.

This article applies the Kantian doctrine of respect for persons to the problem of sweatshops. We argue that multinational enterprises are properly regarded as responsible for the practices of their subcontractors and suppliers. We then argue that multinationalenterprises have the following duties in their off-shore manufacturing facilities: to ensure that local labor laws are followed; to refrain from coercion; to meet minimum safety standards; and to provide a living wage for employees. Finally, we consider and reply to the objection that (...) improving health and safety conditions and providing a living wage will cause greater harm than good. (shrink)

Psychological individualism is motivated by two taxonomic principles: (i) that psychological states are individuated by their causal powers, and (ii) that causal powers supervene upon intrinsic physiological state. I distinguish two interpretations of individualism--the 'orthodox' and the 'alternative'--each of which is consistent with these motivating principles. I argue that the alternative interpretation is legitimately individualistic on the grounds that it accurately reflects the actual taxonomic practices of bona fide individualistic sciences. The classification of homeobox genes in developmental genetics provides an (...) illustration. When applied to the taxonomy of psychological kinds, alternative individualism has some surprising consequences. In particular, externalist taxonomies of thought are consistent with the alternative interpretation, and hence consistent with individualism. I conclude, on this basis, that the individualism/externalism dispute which has long preoccupied philosophy of psychology is an empty one. (shrink)

ABSTRACT:In a series of reports the United Nations Special Representative on the issue of Human Rights and Transnational Corporations has emphasized a tripartite framework regarding business and human rights that includes the state “duty to protect,” the TNC “responsibility to respect,” and “appropriate remedies” for human rights violations. This article examines the recent history of UN initiatives regarding business and human rights and places the tripartite framework in historical context. Three approaches to human rights are distinguished: moral, political, and legal. (...) It is argued that the tripartite framework’s grounding of the responsibility of TNCs to respect human rights is properly understood as moral and not merely as a political or legal duty. A moral account of the duty of TNCs to respect basic human rights is defended and contrasted with a merely strategic approach. The main conclusion of the article is that only a moral account of the basic human rights duties of TNCs provides a sufficiently deep justification of “the corporate responsibility to respect human rights” feature of the tripartite framework.

We review recent developments in ethical pluralism, ethical particularism, Kantian intuitionism, rights theory, and climate change ethics, and show the relevance of these developments in ethical theory to contemporary business ethics. This paper explains why pluralists think that ethical decisions should be guided by multiple standards and why particularists emphasize the crucial role of context in determining sound moral judgments. We explain why Kantian intuitionism emphasizes the discerning power of intuitive reason and seek to integrate that with the comprehensiveness of (...) Kant’s moral framework. And we show how human rights can be grounded in human agency, and explain the connections between human rights and climate change. (shrink)

Denis McManus presents a novel account of Martin Heidegger's early vision of our subjectivity and the world we inhabit. He explores key elements of Heidegger's philosophy, and argues that Heidegger's central claims identify genuine demands that must be met if we are to achieve the feat of thinking determinate thoughts about the world around us.

In recent years, there has been an increasing interest among philosophers of memory in the questions of how to characterize and to account for the temporal phenomenology of episodic memory. One prominent suggestion has been that episodic memory involves a feeling of pastness, the elaboration of which has given rise to two main approaches. On the intentionalist approach, the feeling of pastness is explained in terms of what episodic memory represents. In particular, Fernández has argued that it can be explained (...) in terms of memory representing itself as being caused by a past perceptual experience. On the metacognitive approach, which we have recently developed in, the feeling of pastness results from the monitoring and interpretation of the processing features of episodic remembering. In this paper, we show that the metacognitive approach should be preferred over the intentionalist approach. We argue that intentionalism, and Fernández’ causal self-referential view in particular, ultimately fail as accounts of the feeling of pastness. The difficulties faced by intentionalism allows us to single out three constraints that any satisfactory account of the temporal phenomenology of episodic remembering needs to meet. We conclude by arguing that the metacognitive view satisfies those constraints in a neat way, and as such, that it should be preferred over intentionalism. (shrink)

In “Sweatshops and Respect for Persons” we argued on Kantian grounds that managers of multinational enterprises (MNEs) have the following duties: to adhere to local labor laws, to refrain from coercion, to meet minimum health and safety standards, and to pay workers a living wage. In their commentary on our paper Sollars and Englander challenge some of our conclusions. We argue here that several of their criticisms are based on an inaccurate reading of our paper, and that none of the (...) remaining criticisms successfully challenge our main arguments. By highlighting the shortcomings of their arguments we hope to advance discussion of the ethical treatment of workers in global supply chains. (shrink)

Whenever a structure with a particularly interesting computability-theoretic property is found, it is natural to ask whether similar examples can be found within well-known classes of algebraic structures, such as groups, rings, lattices, and so forth. One way to give positive answers to this question is to adapt the original proof to the new setting. However, this can be an unnecessary duplication of effort, and lacks generality. Another method is to code the original structure into a structure in the given (...) class in a way that is effective enough to preserve the property in which we are interested. In this paper, we show how to transfer a number of computability-theoretic properties from directed graphs to structures in the following classes: symmetric, irreflexive graphs; partial orderings; lattices; rings ; integral domains of arbitrary characteristic; commutative semigroups; and 2-step nilpotent groups. This allows us to show that several theorems about degree spectra of relations on computable structures, nonpreservation of computable categoricity, and degree spectra of structures remain true when we restrict our attention to structures in any of the classes on this list. The codings we present are general enough to be viewed as establishing that the theories mentioned above are computably complete in the sense that, for a wide range of computability-theoretic nonstructure type properties, if there are any examples of structures with such properties then there are such examples that are models of each of these theories.

ABSTRACT:Little theoretical attention has been paid to the question of what obligations corporations and other business enterprises have to the four billion people living at the base of the global economic pyramid. This article makes several theoretical contributions to this topic. First, it is argued that corporations are properly understood as agents of global justice. Second, the legitimacy of global governance institutions and the legitimacy of corporations and other business enterprises are distinguished. Third, it is argued that a deliberative democracy (...) model of corporate legitimacy defended by theorists of political CSR is unsatisfactory. Fourth, it is argued that a Rawlsian theoretical framework fails to provide a satisfactory account of the obligations of corporations regarding global justice. Finally, an ethical conception of CSR grounded in an appropriately modest set of duties tied to corporate relationships is then defended. This position is cosmopolitan in scope and grounded in overlapping arguments for human rights. (shrink)

Wide content and individualist approaches to the individuation of thoughts appear to be incompatible; I think they are not. I propose a criterion for the classification of thoughts which captures both. Thoughts, I claim, should be individuated by their teleological functions. Where teleological function is construed in the standard way - according to the aetiological theory - individuating thoughts by their function cannot produce a classification which is both individualistic and consistent with the principle that sameness of wide content is (...) sufficient for sameness of psychological state. There is, however, an alternative approach to function, the relational theory, which is preferable on independent grounds. A taxonomy of thoughts based on these functions reconciles wide content with individualism. One consequence of individuating thoughts in this way is that intentional content is context sensitive. I discuss some of the implications of context sensitive content. (shrink)
