There are unusual challenges in ethics for RAS. Perhaps the issue can best be summarised as needing to consider “technically informed ethics”. The technology of RAS raises issues that have an ethical dimension, and perhaps uniquely so due to the possibility of moving human decision-making which is implicitly ethically informed to computer systems. Further, if seeking solutions to these problems – ethically aligned design, to use the IEEE’s terminology – then the solutions must be technically meaningful, capable of realisation, capable (...) of assurance, and suitable as a basis for regulation. Thus, ethics for RAS is a rich, complex multi-disciplinary concern, and perhaps more complex than many other ethical issues facing society today. It is also fast-moving. This paper has endeavoured to give an accessible introduction to some of the key issues, noting that many of them are quite subtle, and it is not possible to do them full justice in such a short document. However, we have sought to counterbalance this by giving an extensive list of initiatives, standards, etc. that focus on ethics of RAS and AI, see Annex A. (shrink)

We provide a taxonomy of the two most important debates in the philosophy of the cognitive and neural sciences. The first debate is over methodological individualism: is the object of the cognitive and neural sciences the brain, the whole animal, or the animal--environment system? The second is over explanatory style: should explanation in cognitive and neural science be reductionist-mechanistic, inter-level mechanistic, or dynamical? After setting out the debates, we discuss the ways in which they are interconnected. Finally, we make some (...) recommendations that we hope will help philosophers interested in the cognitive and neural sciences to avoid dead ends. (shrink)

Many philosophers and psychologists argue that out everyday ability to predict and explain the actions and mental states of others is grounded in out possession of a primitive 'folk' psychological theory. Recently however, this theory has come under challenge from the simulation alternative. This alternative view says that human beings are able to predict and explain each other's actions by using the resources of their own minds to simulate the psychological aetiology of the actions of the others. This book and (...) the companion volume Folk Psychology: The Theory of Mind Debate together offer a richly woven fabric of philosophical and psychological theory, which promises to yield real insights into the nature of our mental lives.

Some sensory modalities, such as sight, touch and audition, are arguably spatial, and one way to understand these spatial senses is to investigate spatial representations in them. Here I focus on a specific element in this area— the interplay between perspectival variation and spatial constancy—and discuss recent interdisciplinary works on this topic. With these relevant experimental works, we will see clearly how traditional controversies in philosophy, for example, whether we perceive perspectival shapes as well as objective shapes, and whether any (...) sensory field should be postulated in senses other than vision, can benefit from considerations in empirical sciences.

ABSTRACT Issues concerning the putative perception/cognition divide are not only age-old, but also resurface in contemporary discussions in various forms. In this paper, I connect a relatively new debate concerning perceptual confidence to the perception/cognition divide. The term ‘perceptual confidence’ is quite common in the empirical literature, but there is an unsettled question about it, namely: are confidence assignments perceptual or post-perceptual? John Morrison in two recent papers puts forward the claim that confidence arises already at the level of perception. (...) In this paper, I first argue that Morrison’s case is unconvincing, and then develop one picture on perceptual precision with the notion of ‘matching profile’ and ‘supervaluation’ : 481–495.), highlighting the fact that this is a vagueness account, which is similar to but importantly different from indeterminacy accounts : 156–184.). With this model in hand, there can be rich resources with which to draw a theoretical line between perception and cognition. (shrink)

Substantial research examines the follower consequences of leader alignment of words and deeds, but no research has quantitatively reviewed these effects. This study examines extant research on behavioral integrity and contrasts it with two other constructs that focus on alignment: moral integrity and psychological contract breaches. We compare effect sizes between the three constructs, and find that BI has stronger effects on trust, in-role task performance and citizenship behavior than moral integrity and stronger effects on commitment and OCB than psychological (...) contract breach. These stronger attitudinal consequences run counter to our initial expectations, but they provide evidence of important conceptual distinctions and mechanisms that we articulate. BI theory suggests that BI’s greater performance impact is due to the notion that BI affects communication clarity in addition to attitudes. Results of meta-analytic structural equation modeling are consistent with this proposed dual path of BI’s impact. We highlight avenues for future research on BI and discuss how our findings inform the broader research on leader alignment. (shrink)

According to the theory theory of folk psychology, our engagement in the folk psychological practices of prediction, interpretation and explanation draws on a rich body of knowledge about psychological matters. According to the simulation theory, in apparent contrast, a fundamental role is played by our ability to identify with another person in imagination and to replicate or re-enact aspects of the other person’s mental life. But amongst theory theorists, and amongst simulation theorists, there are significant differences of approach.

Street art is an art form that entails creating public works incorporating the street physically and in their meaning. That physical property is employed as an artistic resource in street art raises two questions. Are street artworks necessarily illegal? Does being illegal change the nature of production and aesthetic appreciation? First, I argue street artworks must be in the street. On my view, both the physical and sociocultural senses of the street can be constitutive of meaning. Second, I argue that (...) illegality is a prototypical and paradigmatic feature of street art. While illegality alone does not make works better than sanctioned street art, it affects the production process and changes what is available to appreciate. (shrink)

Recently, there is a renewed debate concerning the role of perspective in vision. Morales et al. (2020) present evidence that, in the case of viewing a rotated coin, the visual system is sensitive to what has often been called “perspectival shapes.” It has generated vigorous discussions, including an online symposium by Morales and Cohen, an exchange between Linton (2021) and Morales et al. (2021), and most recently, a fierce critique by Burge and Burge (2022), in which they launch various conceptual (...) and empirical objections. Although Morales and Firestone (2022) have responded to them recently, and we are in agreement with Morales and Firestone in general, there are further problems in Burge and Burge (2022) that are worth highlighting. The main point of this comment is that what the Burge–Burge team call “viewpoint-dependent relational properties” are simply instances of what the Morales–Firestone team call “perspectival shapes”; the confusion arises from Burge and Burge’s misconstrual of Morales et al.’s claims. This shows that conceptually, the two teams are in large agreement, as Morales and Firestone (2022) also point out, and the focus should be put on the empirical disagreements, which has been covered by Morales and Firestone (2022). Relatedly, we argue that Burge and Burge (2022) misinterpret Morales et al. (2020) as supporting a new entity in perception science, and that this misinterpretation is a primary source of their apparent disagreement. This is worth pointing out because such misunderstanding generates many unnecessary quarrels that hinder progress. (shrink)

Arash Abazari's Hegel's Ontology of Power is a superb study of the relevance of Hegel's logic to Marx's theory. Hegel is often dismissed by Marxists as an ‘idealist’ denying the reality of the world, as if Hegel were Bishop Berkeley with a German accent.1 Abazari recognizes this is not the case: ‘(T)he logical categories are not self-standing, but shadow, or track, the empirical world’ (Abazari 2020: 7). But the world in its full actuality does not simply consist of the objects (...) we sense or perceive. It is intrinsically intelligible, and its intelligibility can be comprehended only in thought. When it is, the ‘idealist’ thesis of the identity (in difference) of thought and being holds. Anyone asserting a truth claim implicitly asserts this identity. In so far as Marx asserts that Capital comprehends the capitalist mode of production, he too is an ‘idealist’ in the Hegelian sense of the term. (shrink)

Avicenna (d. 1037) and Tūsī (d. 1274) have different doctrines on the contradiction and conversion of the absolute proposition. Following Avicenna's presentation of the doctrine in Pointers and reminders, and comparing it with what is given in Tūsī's commentary, allow us to pinpoint a major reason why Avicenna and Tūsī have different treatments of the modal syllogistic. Further comparison shows that the syllogistic system Rescher described in his research on Arabic logic more nearly fits Tūsī than Avicenna. This in turn (...) has consequences for analysing Avicenna's logic, and for writing the history of a fascinating period of change and diversity in the discipline in the medieval Islamic world.

This paper is about the contemporary debate concerning folk psychology – the debate between the proponents of the theory theory of folk psychology and the friends of the simulation alternative.¹ At the outset, we need to ask: What should we mean by this term ‘folk psychology’?

After an introduction to the major issues confronting intellectuals, this book explores the various aspects of the intellectual's role including: * philosophers and academics who have tried to define the function of the intellectual * how intellectuals have assumed the status of the conscience of the nation and the voice of the oppressed * the interaction of intellectuals with Marxism * the place of the intellectual in American society Covering regions as diverse as Israel, Algeria, Britain, Ireland, central Europe and (...) America, this collection considers the question of whether the intellectual can still lay claim to the language of truth. In answering, this study tells us much about the modern world in which we live. _Coverage includes the following thinkers:_ Gramsci, Weber, Yeats, Auden, Levy, Mailer, Walzer, Marx and many more.

This study draws on semistructured interviews with 19 white, rural, straight-identified men who have sex with men to understand how they perceive their gender and sexuality. It is among the first to use straight men’s own narratives, and helps address the underrepresentation of rural masculinities research. Through complex interpretive processes, participants reworked non-normative sexual practices—those usually antithetical to rural masculinities—to construct normative masculinity. Most chose other masculine, white, and straight or secretly bisexual men as partners for secretive sex without romantic (...) involvement. By choosing these partners and having this type of sex, the participants normalized and authenticated their sexual encounters as straight and normatively masculine. The participants engaged in bud-sex, a specific type of male–male sex that reinforced their rural masculinity and heterosexuality. The married men framed sex with men as less threatening to marriage than extramarital sex with women, helping to preserve a part of their lives that they described as central to their straightness. The results highlight the flexibility of heterosexuality; the centrality of heterosexuality to normative rural masculinity; how similar sexual practices carry different meanings across contexts and populations; and the social construction of masculinities and sexualities by age, race, gender, time period, and place.

It remains controversial whether touch is a truly spatial sense or not. Many philosophers suggest that, if touch is indeed spatial, it is only through its alliances with exploratory movement, and with proprioception. Here we develop the notion that a minimal yet important form of spatial perception may occur in purely passive touch. We do this by showing that the array of tactile receptive fields in the skin, and appropriately relayed to the cortex, may contain the same basic informational building (...) blocks that a creature navigating around its environment uses to build up a perception of space. We illustrate this point with preliminary evidence that perception of spatiotemporal patterns on the human skin shows some of the same features as spatial navigation in animals. We argue (a) that the receptor array defines a ‘tactile field’, (b) that this field exists in a minimal form in ‘skin space’, logically prior to any transformation into bodily or external spatial coordinates, and (c) that this field supports tactile perception without integration of concurrent proprioceptive or motor information. The basic cognitive elements of space perception may begin at lower levels of neural and perceptual organisation than previously thought. (shrink)

In this letter we focus on the cognitive science of consciousness. The general message is that, while this interdisciplinary area has made much progress in recent years, there is a tendency of downplaying conceptual issues, and therefore underestimating the difficulties of various problems. We briefly focus on a few prominent examples only, due to the space limit, but the general message should be clear: this recent tendency can be problematic for the progress of the consciousness branch of cognitive sciences.

Several articles have recently appeared arguing that there really are no viable alternatives to mechanistic explanation in the biological sciences. This claim is meant to hold both in principle and in practice. The basic claim is that any explanation of a particular feature of a biological system, including dynamical explanations, must ultimately be grounded in mechanistic explanation. There are several variations on this theme, some stronger and some weaker. In order to avoid equivocation and miscommunication, in section 1 we will (...) argue that mechanistic explanation is defined by localization and decomposition. In section 2 we will argue that systems neuroscience contains explanations that violate both localization and decomposition on any non-trivial construal of these concepts. Therefore, in section 3 we conclude the mechanistic model of explanation either needs to stretch to now include explanations wherein localization or decomposition fail, or acknowledge that there are counter-examples to mechanistic explanation in the biological sciences. We will also consider consequences and possible replies on the part of the mechanist in section 3. (shrink)

Gyula Klima maintains that Anselm's ontological argument is best understood in terms of a theory of reference that was made fully explicit only by later medievals. I accept the interpretative claim but offer here two objections to the argument so interpreted. The first points up a certain ambiguity in Klima's formulation of the argument, the correction of which requires a substantive revision of the argument's conclusion. The second exploits the notion of semantic closure introduced by Tarski. Klima offers the atheist (...) an ?out? by drawing a distinction between constitutive and parasitic reference. I argue that using Klima's preferred description (?the thought object than which no thought object can be thought to be greater?) to refer constitutively to God results in conceptual closure, a condition analogous to semantic closure that renders the instant conceptual scheme inconsistent and subject to paradox. Although the proof ultimately fails, Klima's development of the notions of constitutive and parasitic reference has important and far-reaching implications. (shrink)

In this talk, we defend extended cognition against several criticisms. We argue that extended cognition does not derive from armchair theorizing and that it neither ignores the results of the neural sciences, nor minimizes the importance of the brain in the production of intelligent behavior. We also argue that explanatory success in the cognitive sciences does not depend on localist or reductionist methodologies; part of our argument for this is a defense of what might be called ‘holistic science’.

In a world of confrontations between numerous cultures, traditions, languages, and religions, the meaning of “human” and “humanism” reaches a higher level of “humanness.” The pluralism of cultural, political, and religious outlook creates new options and alternative interpretations of what constitutes the “human.” True humanness is always there, open and accessible to all, with nothing being hidden or obscured. At the same time, true humanness is also a matter of doing, not just being. To be “true” is to live the (...) truth, to be with it, and to be part of it. We exist inside this truth as a passion, which informs all the decisions we make in life. So true humanness is not something objective and static, something to be studied from a distance; true humanness is an up-close and personal way of living, a mode of existence, something that is relational. Our way toward a more complex understanding of humanness faces similar obstacles as a yogi encounters on his way to the final way of Yoga. Patañjali in his Yoga Sutras describes these obstacles—kleshas—as the afflictions of the human mind, or destructive and disturbing emotions: ignorance, ego, attachment, aversion, and clinging to life. A higher understanding of “humanness” will not be reached without an ethical engagement of individuals, as well as formal and informal commitment of institutions and nations. Such an endeavor will consequently reveal yet-undiscovered human potential, leading to a renaissance of our acting, thinking, and believing. (shrink)

ABSTRACTThe concept of need is often proposed as providing an additional or alternative criterion to cost‐effectiveness in making allocation decisions in health care. If it is to be of practical value it must be sufficiently precisely characterized to be useful to decision makers. This will require both an account of how degree of need for an intervention is to be determined and a prioritization rule that clarifies how degree of need and the cost of the intervention interact in determining the (...) relative priority of the intervention. Three common features of health care interventions must be accommodated in a comprehensive theory of need: the probabilistic nature of prognosis ; the time course of effects; and the fact that the most effective treatments often combine more than one intervention. These common features are problematic for the concept of need. We outline various approaches to prioritization on the basis of need and argue that some approaches are more promising than others.

I should like to thank Ben Fine, Costas Lapavitsas and Dimitris Milonakis for their stimulating and detailed comments. In the limited space available, I cannot respond to every criticism. A number of criticisms appear to be a matter of mere semantics. In the Marxian literature, the term ‘crisis’ is often used to refer to extended downturns as well as to short and sharp declines. And Marx himself defines the organic composition of capital as the value composition considered ‘in so far (...) as this is determined by its technical composition and reflects it’, which is how the value composition is considered in my paper. Nor will I respond to the charge that my ‘use of Grossmann is mechanical and unpersuasive’, since I am not sure what exactly the objection is. Firstly, I will take up the criticisms regarding the logical structure of Capital. Then I move on to consider one substantive issue raised regarding the tendency for the falling rate of profit. I will next respond to criticism of my treatment of the relation between systematic and historical dialectics. Finally, I respond to criticism of my main thesis overall. (shrink)

Knowledge was a major issue in science and philosophy in the twentieth century. Its first irruption was in the heated controversy concerning the foundations of mathematics. To justify his rejection of the use of the actual infinite in mathematical reasoning, Brouwer has made the construction of mathematical objects dependent on the knowing subject. This approach was rejected by the mainstream of analytical philosophers who feared a fall into pyschologism. Several years later, the question of the progress of scientific knowledge was (...) put forward in the thirties by the post-positivist philosophers to fill the vacuum in the philosophy of science following the demise of the logical positivism programme. The answers given to these questions have deepened the already existing gap between philosophy and the history and practice of science. While the positivists argued for a spontaneous, steady and continuous growth of scientific knowledge the post-positivists make a strong case for a fundamental discontinuity in the development of science which can only be explained by extrascientific factors. The political, social and cultural environment, the argument goes on, determine both the questions and the terms in which they should be answered. Accordingly, the sociological and historical interpretation involves in fact two kinds of discontinuity which are closely related: the discontinuity of science as such and the discontinuity of the more inclusive political and social context of its development. More precisely it explains the discontinuity of the former by the discontinuity of the latter subordinating in effect the history of science to the wider political and social history. The underlying idea is that each historical and social context generates scientific and philosophical questions of its own. From this point of view the question surrounding the nature of knowledge and its development are entirely new topics typical of the twentieth century social context reflecting both the level and the scale of the development of science. To the surprise of modern historians of science and philosophy, the same kind of questions, which would allegedly be new topics specific to the twentieth century concerning the nature of knowledge and its progress, were already raised more than eleven centuries earlier in the context of the Arabic tradition which, as we discuss further on, developed a trans-cultural and trans-national concept of the unity of science (see the contributions of Deborah Black and Jon McGinnis which tackle the issue of the nature of knowledge). The neglect of the Arabic tradition in philosophy of science is a major a gap not only in the development of science but a fundamental flaw in the writing of its history and philosophy caused by the total reduction of epistemology to political and social history of science. How has this period of the history of science and philosophy come to be ignored? In what circumstances were the questions akin to the nature of knowledge raised in the first place? What is the relation between on the one hand the questions of knowledge and its growth and on the other hand the unity of science in the Arabic tradition? The answers to some of these questions are the aim of the present volume, the first of the series Logic, Epistemology and the Unity of Science to be devoted to a so-called non-western tradition. Let us first highlight in a kind of overview some landmarks concerning the timing of the emergence of the Arabic tradition and its significance for the history of science. (shrink)

Individuals use their capacity for autonomy to express preferences regarding food choices. Food choices are fundamental, universal, and reflect a diversity of interests and cultural preferences. Traditionally, autonomy is cast in only epistemic terms, and the social and political dimension of it, where autonomy obstruction tends to arise, is omitted. This reflects problematic limits in the Cartesian notion of the individual. Because this notion ignores context and embodiment, the external and internal constraints on autonomy that extend from social location are (...) not considered. Therefore, reconceptions of the individual and autonomy which emphasize social location and relational interdependency are needed. To combat autonomy obstruction, individuals can appeal to community and community autonomy as a social mechanism. Communities are social groups characterized by people living in places with shared goals. Recognizing their interdependency, individuals can organize as communities in order to accomplish objectives that they cannot on their own. While community autonomy is valuable unto itself, it can also enhance individual autonomy. (shrink)

Free market environmentalists believe that the extension of private property rights and market transactions is sufficient to address environmental difficulties. But there is no invisible hand operating in markets that ensures that environmentally sound practices will be employed just because property rights are in private hands. Also, liability laws and the court systems cannot be relied upon to force polluters to internalize the social costs of pollution. Third, market prices do not provide an objective measure of environmental matters. Finally, there (...) is a right to a livable environment that justifies regulations protecting the public from unreasonable environmental risks. (shrink)

Chris Arthur‟s body of work counts as a very important and original contribution to systematic dialectics, and I have profited immensely from his writings over the years. However we disagree on a number of points. Some have to do with the relatively secondary question of the intellectual relationship between Hegel and Marx; others involve more substantive matters. In his reply to my review of Joseph McCarney‟s Hegel on History Arthur distinguishes three different versions of the thesis that there is a (...) “homology” between the logic of capital (in a Marxian understanding of it) and Hegel‟s “idea.” I shall comment briefly on each and then conclude with a general remark.

In his recent work The Myth of Dialectics John Rosenthal presents a forceful polemic against Hegel and Marxists sympathetic to the Hegelian legacy. The methodology Hegel employed, his metaphysical assertions, his rejection of the principles of formal logic, and the political implications of his standpoint, are all fundamentally incompatible with Marx’s perspective, according to Rosenthal. While Rosenthal grants that Marx did make use of Hegelian motifs in his theory of value, even this is not to Hegel’s credit: the very perversity (...) of Hegel’s thought made it useful for the comprehension of the perversity of capital. In this paper I argue that a close and reasonably charitable reading of Hegel’s Logic reveals a quite different picture of his methodology and ontological commitments from that presented by Rosenthal. While there are profound substantive differences between the Hegelian and Marxian 1 perspectives on capitalist society, it is not the case that Hegel’s Logic is homologous with capital. The Logic provides helpful conceptual resources for a critique of capital. In the final section of the paper five areas are briefly sketched in which Hegelian dialectical logic remains of contemporary interest. (shrink)

This paper investigates the complicated relations between various versions of naturalism, behaviorism, and mentalism within the framework of W. V. O. Quine's thinking. It begins with Roger Gibson's reconstruction of Quine's behaviorisms and argues that it lacks a crucial ontological element and misconstrues the relation between philosophy and science. After getting clear of Quine's naturalism, the paper distinguishes between evidential, methodological, and ontological behaviorisms. The evidential and methodological versions are often conflated, but they need to be clearly distinguished in order (...) to see whether Quine's argument against mentalism is cogent. The paper argues that Quine's naturalism supports only the weakest version of behaviorism, that is, the evidential one, but this version is compatible with mentalistic semantics. Quine's opposition to mentalism is an overreaction from the behaviorist camp. By contrast, Jerry Fodor's objection to Jose Luis Bermudez is an overreaction from the opposite direction. (shrink)

This article attempts to highlight the importance of including research sustainability as imperative when assessing human medical research in terms of ethical principles. Using a scoping review of recent literature, the complexity of research sustainability is highlighted with key themes and concepts surrounding this important topic being recognized and discussed.

An example of a research sustainability evaluation tool which is currently being piloted (...) has been provided for possible adaptation and use by Ethics Committees and Institutional Review Boards to bolster the concept and inclusion of sustainability during the research approval process.

Hegel conceptualized the capitalist economy as a system of needs, with commodities and money serving as means to human ends. While anticipating Marx’s criticisms of certain tendencies in capitalism, Hegel insisted that higher-order institutions, especially those of the modern state, could put them out of play and establish a reconciliation of universality, particularity, and individuality warranting rational affirmation. Hegel, however, failed to comprehend the emergence of capital as a dominant subject, subordinating human ends under its end. The structural coercion, domination, (...) and exploitation inherent in the capital/wage labor relationship illustrate that point, as does the depoliticization of inherently political matters in capitalist market societies. The reconciliation of universality, particularity, and individuality Hegel endorsed requires a form of socialism incorporating deliberative democracy in local workplaces and communities, conjoined with representative bodies on regional, national, and ultimately global levels.

In recent publications Paolo Virno and Carlo Vercellone have called attention to Marx’s category of the general intellect in theGrundrisse, and to the unprecedented role its diffusion plays in contemporary capitalism. According to Virno, the flourishing of the general intellect, which Marx thought could only take place within communism, characterises post-Fordist capitalism. Vercellone adds that Marx’s account of the real subsumption of living labour under capital is obsolete in contemporary cognitive capitalism. Both authors regard Marx’s value theory as historically obsolete. (...) I argue that these views rest on a confusion of value and wealth, a neglect of Marx’s account of the role of ‘free gifts’ to capital, an underestimation of the role of the general intellect in the period prior to the rise of post-Fordism/cognitive capitalism, and an underestimation of the restrictions on the diffusion of the general intellect in contemporary capitalism.

In the present article, I attempt to relate Saul Kripke's “sceptical paradox” to some issues about the self; specifically, the relation between the self and its mental states and episodes. I start with a brief reconstruction of the paradox, and venture to argue that it relies crucially on a Cartesian model of the self: the sceptic regards the Wittgensteinian “infinite regress of interpretation” as the foundation of his challenge, and this is where he commits the crucial mistake. After the diagnosis, (...) I attempt to sketch my own model of the self and its mental states and episodes. This tentative picture binds meaning and the self together, stressing the subjective aspect of meaning without committing the same fallacy. The solution ventured here is relatively independent of the secondary literatures on the sceptical paradox of following rules, for it aims to provide a new angle to understand and meet the challenge presented by the sceptic.

To reduce the spread of the human immunodeficiency virus (HIV), Granich et al. 1 ( 2009 ) have proposed a new strategy for universal voluntary HIV testing immediately followed by antiretroviral therapy. Although this proposal is likely to benefit the partners of those affected and thus promote public health, it is by no means clear that it benefits the infected people themselves and indeed it may be harmful. Since the proposal involves an intervention that is not clinically indicated, it falls (...) foul of the normal ethical standards of clinical medicine, which is to act in the best interests of patients. Neither is it a measure that would be imposed under the protection of public health law on people who are seen as representing such danger to others that significant restrictions in liberty are appropriate. Thus, the proposal represents a third category of public health measure. We argue that a coherent ethical framework including a robust process is appropriate to proposals of this kind and that medical research offers a useful model since some research, like this proposal, is motivated not by the interests of the individual participants but by the common good. We outline some possible elements of such an ethical framework. (shrink)
