As zoos have developed more successful captive breeding programs, they now face a question of what to do about “surplus” animals. One strategy used by European zoos in recent years has been to allow animals to breed freely, then kill unwanted offspring. I argue that this strategy wrongs the animals in question and that the justifications that have been offered for the practice are inadequate. I provide background on the practice, discuss the moral status of animals and potential grounds for (...) the prima facie duty not to kill, and then examine and ultimately dismiss justifications for killing in this case.

Targeted killings have traditionally been viewed as a dirty tactic, even within war. However, I argue that just combatants actually have a prima facie duty to use targeted strikes against military and political leadership rather than conventional methods of fighting. This is because the leaders of a military engaging in aggression are typically responsible for the wrongful harms they threaten, whereas significant numbers of their solders usually will not be. Conventional warfare imposes significant risks on soldiers who are not liable (...) to be killed, violating their rights. Narrowly targeted strikes frequently provide a less-wrongful alternative. Consequently, there is a prima facie duty to conduct such strikes, and to exercise “due care” if engagement with conventional forces becomes necessary. (shrink)

This book is the most comprehensive treatment available of one of the most urgent - and yet in some respects most neglected - problems in bioethics: decision-making for incompetents. Part I develops a general theory for making treatment and care decisions for patients who are not competent to decide for themselves. It provides an in-depth analysis of competence, articulates and defends a coherent set of principles to specify suitable surrogate decisionmakers and to guide their choices, examines the value of advance (...) directives, and investigates the role that considerations of cost ought to play in decisions concerning incompetents. Part II applies this theoretical framework to the distinctive problems of three important classes of individuals, many of whom are incompetent: minors, the elderly and psychiatric patients. The authors' approach combines a probing analysis of fundamental issues in ethical theory with a sensitive awareness of the concrete realities of health care institutions and the highly personal and individual character of difficult practical problems. Its broad scope will appeal to health professionals, moral philosophers and lawyers alike. (shrink)

This book, written by four internationally renowned bioethicists and first published in 2000, was the first systematic treatment of the fundamental ethical issues underlying the application of genetic technologies to human beings. Probing the implications of the remarkable advances in genetics, the authors ask how should these affect our understanding of distributive justice, equality of opportunity, the rights and obligations as parents, the meaning of disability, and the role of the concept of human nature in ethical theory and practice. The (...) book offers a historical context to contemporary debate over the use of these technologies by examining the eugenics movement of the late nineteenth and early twentieth centuries. The questions raised in this book will be of interest to any reflective reader concerned about science and society and the rapid development of biotechnology, as well as to professionals in such areas as philosophy, bioethics, medical ethics, health management, law, and political science.

This book follows hard upon Korsgaard's The Sources of Normativity. Both present the author's influential version of a Kantian theory of normative ethics and metaethics. Whereas The Sources of Normativity was a systematic investigation of "normativity" written as a single unit, the present volume is a collection of previously published papers, some of them already well known and much discussed, dating between 1983 and 1993. By the nature of the case, one might expect less thematic unity in this book than (...) in the other one, but the present book is a deeper and more wide ranging presentation of the author's views. Korsgaard's historical focus in The Sources of Normativity is less on Kant and more on the British moralists. Creating the Kingdom of Ends deals quite explicitly with the interpretation of Kant's moral philosophy. The papers in this book contain, in my judgment, the heart of Korsgaard's work: a variety of fresh and illuminating insights into Kant's moral theory and its relation to contemporary ethical theory which have helped to reshape the image of Kant's ethics and to refocus the issues dealt with in current moral philosophy. Or to make claims less grand but of more immediate relevance to this review, there is no question that some of the papers in this book have helped to reshape both the present writer's image of Kant's ethics and his conception of the way questions of ethical theory should be addressed. I hope below to say something both about where I think Korsgaard has gotten these matters right, and where I find her position either unclear or dubious. (shrink)

As arti® cial intelligence moves ever closer to the goal of producing fully autonomous agents, the question of how to design and implement an arti® cial moral agent (AMA) becomes increasingly pressing. Robots possessing autonomous capacities to do things that are useful to humans will also have the capacity to do things that are harmful to humans and other sentient beings. Theoretical challenges to developing arti® cial moral agents result both from controversies among ethicists about moral theory itself, and from (...) computational limits to the implementation of such theories. In this paper the ethical disputes are surveyed, the possibility of a `moral Turing Test ’ is considered and the computational di culties accompanying the diŒerent types of approach are assessed. Human-like performance, which is prone to include immoral actions, may not be acceptable in machines, but moral perfection may be computationally unattainable. The risks posed by autonomous machines ignorantly or deliberately harming people and other sentient beings are great. The development of machines with enough intelligence to assess the eŒects of their actions on sentient beings and act accordingly may ultimately be the most important task faced by the designers of arti® cially intelligent automata.

This masterful work on Kant's Religion within the Boundaries of Mere Reason explores Kant's treatment of the Idea of God, his views concerning evil, and the moral grounds for faith in God. Kant and Religion works to deepen our understanding of religion's place and meaning within the history of human culture, touching on Kant's philosophical stance regarding theoretical, moral, political, and religious matters. Wood's breadth of knowledge of Kant's corpus, philosophical sharpness, and depth of reflection sheds light not only on (...) Kant, but also on the fate of religion and its relation to philosophy in the modern world. (shrink)

What determines qualitative sameness and difference? This book explores four principal accounts of the ontological basis of properties, including universals, trope theory, resemblance nominalism, and class nominalism, considering the assumptions and ontolological commitments which are required to make each into a plausible account of properties. -/- The latter half of the book investigates the applications of property theory and the different conceptions of properties which might be adopted with these in mind: first, the possibility and desirability of individuating properties, and (...) the distinction between sparse and abundant conceptions of properties; second, the distinction between intrinsic and extrinsic properties; third, the relationship between properties and their causal powers, and whether this is necessary or contingent; fourth, the relationship between properties and causation, modality, and laws of nature; finally, whether properties exist objectively, and if they do, what our epistemic position is with respect to such entities.

This book explores Kant's views on the concept of God and on the attempt to demonstrate God's existence as a means of understanding Kant's work as a whole and of achieving a proper appreciation of the contents of Kant's moral faith.

This paper presents an ‘over-representational’ account of blurred visual experiences. The basic idea is that blurred experiences provide too much, inconsistent, information about objects’ spatial boundaries, by representing them as simultaneously located at multiple locations. This account attempts to avoid problems with alternative accounts of blurred experience, according to which blur is a property of a visual field, a way of perceiving, a form of mis-representation, and a form of under-representation.

Which nonhuman animals experience conscious pain?1 This question is central to the debate about animal welfare, as well as being of basic interest to scientists and philosophers of mind. Nociception—the capacity to sense noxious stimuli—is one of the most primitive sensory capacities. Neurons functionally specialized for nociception have been described in invertebrates such as the leech Hirudo medicinalis and the marine snail Aplysia californica (Walters 1996). Is all nociception accompanied by conscious pain, even in relatively primitive animals such as Aplysia, (...) or is it the case, as some philosophers continue to maintain, that conscious experiences are the exclu- sive province of human beings? What philosophical and scientific resources are presently available for assessing claims lying between these extremes? (shrink)

This paper has two aims. The first is to use contemporary discussions of naïve realist theories of perception to offer an interpretation of Merleau-Ponty’s theory of perception. The second is to use consideration of Merleau-Ponty’s theory of perception to outline a distinctive version of a naïve realist theory of perception. In a Merleau-Pontian spirit, these two aims are inter-dependent.

Recently something close to a consensus about the best way to naturalize the notion of biological function appears to be emerging. Nonetheless, teleological notions in biology remain controversial. In this paper we provide a naturalistic analysis for the notion of natural design. Many authors assume that natural design should be assimilated directly to function. Others find the notion problematic because it suggests that evolution is a directed process. We argue that both of these views are mistaken. Our naturalistic account does (...) not simply equate design with function. We argue that the distinction between function and design is important for understanding the evolution of the physical and behavioral traits of organisms. (shrink)

Much of the debate about the ethics of enhancement has proceeded according to two framing assumptions. The first is that although enhancement carries large social risks, the chief benefits of enhancement are to those who are enhanced (or their parents, in the case of enhancing the traits of children). The second is that, because we now understand the wrongs of state-driven eugenics, enhancements, at least in liberal societies, will be personal goods, chosen or not chosen in a market for enhancement (...) services. This article argues that both framing assumptions must be rejected, once it is understood that some enhancements— especially those that are most likely to garner resources and become widespread— will increase human productivity. Once one appreciates the productivity-increasing potential of enhancements, one can begin to see that enhancement need not be primarily a zero sum affair, that the social costs of forgoing enhancements may be great, and that the state may well take an interest in facilitating biomedical enhancements, just as it does in facilitating education and other productivity-increasing traditional enhancements. Appreciating the productivity-increasing potential of enhancements also makes it possible to view the enhancement debate in a new light, through the lens of the ethics of development. (shrink)

This paper develops a form of transcendental naïve realism. According to naïve realism, veridical perceptual experiences are essentially relational. According to transcendental naïve realism, the naïve realist theory of perception is not just one theory of perception amongst others, to be established as an inference to the best explanation and assessed on the basis of a cost-benefit analysis that weighs performance along a number of different dimensions: for instance, fidelity to appearances, simplicity, systematicity, fit with scientific theories, and so on. (...) Rather, naïve realism enjoys a special status in debates in the philosophy of perception because it represents part of the transcendental project of explaining how it is possible that perceptual experience has the distinctive characteristics it does. One of the potentially most interesting prospects of adopting a transcendental attitude towards naïve realism is that it promises to make the naïve realist theory of perception, in some sense, immune to falsification. This paper develops a modest form of transcendental naïve realism modelled loosely on the account of the reactive attitudes provided by Strawson in ‘Freedom and Resentment’, and suggests one way of understanding the claim that naïve realism is immune to falsification.

Teleological terms such as "function" and "design" appear frequently in the biological sciences. Examples of teleological claims include: A (biological) function of stotting by antelopes is to communicate to predators that they have been detected. Eagles' wings are (naturally) designed for soaring. Teleological notions were commonly associated with the pre-Darwinian view that the biological realm provides evidence of conscious design by a supernatural creator. Even after creationist viewpoints were rejected by most biologists there remained various grounds for concern about the (...) role of teleology in biology, including whether such terms are: 1. vitalistic (positing some special "life-force"); 2. requiring backwards causation (because future outcomes explain present traits); 3. incompatible with mechanistic explanation (because of 1 and 2); 4. mentalistic (attributing the action of mind where there is none); 5. empirically untestable (for all the above reasons). Opinions divide over whether Darwin's theory of evolution provides a means of eliminating teleology from biology, or whether it provides a naturalistic account of the role of teleological notions in the science. Many contemporary biologists and philosophers of biology believe that teleological notions are a distinctive and ineliminable feature of biological explanations but that it is possible to provide a naturalistic account of their role that avoids the concerns above. Terminological issues sometimes serve to obscure some widely-accepted distinctions. (shrink)

In «Naturalized Epistemology and the Law of Evidence Revisited», the original target article for the various refutations that I comment on here, I revisited through a slightly different lens the subject of the article that I coauthored with Brian Leiter close to twenty years ago. That article has prompted four responses from Professors Pardo, Spellman, Muffato, and Enoch. Professors Pardo and Spellman basically accept the implications of the original article and offer useful but friendly amendments. Prof. Muffato apparently does not (...) want to dispute over my ground and so changes the subject, and in doing so offers a number of interesting points. Only the fourth, Prof. Enoch, has the same doubts about the utility of my original article as I do of the genre that gave rise to it. I can thus be quite brief in discussing professors Pardo, Spellman, and Muffato, but it will take bit more effort to lay out the limits of Prof. Enoch’s analysis. (shrink)

We revisit Naturalized Epistemology and the Law of Evidence, published twenty years ago. The evolution of the relative plausibility theory of juridical proof is offered as evidence of the advantage of a naturalized approach to the study of the field and law evidence. Various alternative explanations of aspects of juridical proof from other disciplines are examined and their shortcomings described. These competing explanations are similar in their reductive, a priori approaches that are at odds with an empirically oriented naturalized approach. (...) The shortcomings of the various a priori approaches are driven by their common methodological commitments to employing weird hypotheticals to engage in intuition mining about the American legal systems that in turn ignore important aspects of the actual legal systems and consistently make impossible epistemological demands. As a result, both their descriptions of and prescriptions for American legal systems are implausible, unlike the relative plausibility theory. (shrink)

The book uses evolutionary principles to explain tribalism, a way of thinking and acting that divides the world into Us versus Them and achieves cooperation within a group at the expense of erecting insuperable obstacles to cooperation among groups. Tribalism represents political controversies as supreme emergencies in which ordinary moral constraints do not apply and as zero-sum, winner take all contests. Tribalism not only undermines democracy by ruling out compromise, bargaining, and respect for the Other; it also reverses one of (...) the most important milestones of progress in how we understand morality: the insight that morality is not a list of commands to be unthinkingly followed, but rather that morality centrally involves the giving and taking of reasons among equals. Tribalism rejects this insight by branding the Other as a being who is incapable of reasoning. (shrink)

According to naïve realist (or primitivist) theories of colour, colours are sui generis mind-independent properties. The question that I consider in this paper is the relationship of naïve realism to what Mark Johnston calls Revelation, the thesis that the essential nature of colour is fully revealed in a standard visual experience. In the first part of the paper, I argue that if naïve realism is true, then Revelation is false. In the second part of the paper, I defend naïve realism (...) against a number of objections.

Ethical analyses of biomedical human enhancement often consider the issue of authenticity — to what degree can the accomplishments of those utilizing biomedical enhancements be considered authentic or worthy of praise? As research into Brain-Computer Interface technology progresses, it may soon be feasible to create a BCI device that enhances or augments natural human intelligence through some invasive or noninvasive biomedical means. In this article we will review currently existing BCI technologies and to what extent these can be said to (...) enhance or augment the capabilities of the respective users, describe one hypothetical type of BCI device that could augment or enhance a specific aspect of human knowledge — namely, mathematical ability, and relate these concepts to the active externalism view of the extended mind as espoused by Clark and Chalmers in order to argue that knowledge of mathematics derived from the usage of a BCI and the application thereof constitutes authentic knowledge and achievement.

In response to recent calls to extend the underlying theories used in the literature :375–413, 2005; Craft in J Bus Ethics 117:221–259, 2013), we review the usefulness of social norm theory in empirical business ethics research. We begin by identifying the seeds of social norm theory in Adam Smith’s The Theory of Moral Sentiments, the Glasgow Edition, Oxford University Press, Oxford, 1759/1790) seminal work, The Theory of Moral Sentiments. Next, we introduce recent theory in social norm activation by Bicchieri and (...) compare the new theory to two theoretical frameworks found in the literature: Kohlberg’s Handbook of socialization theory and research, Rand McNally, Chicago, IL, 1969; in: Lickona Moral development and behavior, Holt, Rinehart & Winston, New York, 1976) theory of moral development and Cialdini and Trost’s The handbook of social psychology, Oxford University Press, Boston, 1998) taxonomy of social norms. We argue that the new theory provides useful insights by emphasizing the ability of situational cues and information to generate common expectations for social/moral norms. The theory is particularly useful for empirical research in business ethics because it gives both organizational and individual factors a role in motivating norm-based behavior. To demonstrate this usefulness, we present examples where the theory has been effectively applied in experimental accounting research to generate new insights. We conclude by citing specific examples where the theory may prove useful in empirical business ethics research. (shrink)

Feminist theory needs both explanatory-diagnostic and anticipatory-utopian moments in order to be truly critical and truly feminist. However, the explanatory-diagnostic task of analyzing the workings of gendered power relations in all of their depth and complexity seems to undercut the very possibility of emancipation on which the anticipatory-utopian task relies. In this paper, I take this looming paradox as an invitation to rethink our understanding of emancipation and its relation to the anticipatory-utopian dimensions of critique, asking what conception of emancipation (...) is compatible with a complex explanatory-diagnostic analysis of contemporary gender domination as it is intertwined and entangled with race, class, sexuality, and empire. I explore this question through an analysis of two specific debates in which the paradoxical relationship between power and emancipation emerges in particularly salient and seemingly intractable forms: debates over subjection and modernity. Drawing on the work of Michel Foucault, I argue that a negativistic conception of emancipation offers the best way for feminist critical theory to transform the paradox of power and emancipation into a productive tension that can fuel critique.

The contents of our conscious mind can seem unpredictable, whimsical, and free from external control. When instructed to attend to a stimulus in a work setting, for example, one might find oneself thinking about household chores. Conscious content thus appears different in nature from reflex action. Under the appropriate conditions, reflexes occur predictably, reliably, and via external control. Despite these intuitions, theorists have proposed that, under certain conditions, conscious content resembles reflexes and arises reliably via external control. We introduce the (...) Reflexive Imagery Task, a paradigm in which, as a function of external control, conscious content is triggered reliably and unintentionally: When instructed to not subvocalize the name of a stimulus object, participants reliably failed to suppress the set-related imagery. This stimulus-elicited content is considered ‘high-level’ content and, in terms of stages of processing, occurs late in the processing stream. We discuss the implications of this paradigm for consciousness research. (shrink)

I Can we make promises to ourselves? This is a question that has not received much consideration in the large body of philosophical work on promising. And in what commentary there is, the answer is uniformly negative. I think this negativity is a mistake, and that the conventional view that we can't make reflexive promises is wrong. I also think that this has some important implications for promissory theory in general. In what follows, I will attempt to argue for the (...) first of these two claims, and to briefly outline my reasons for the second. (shrink)

This essay introduces a running symposium on the work of Richard Rorty and its legacy fifteen years after his passing. The arc of Rorty's thought defines a trajectory through American pragmatism, tracing a variation unimagined until he expressed it.

Methodologically rigorous description, analysis, and critique of postmodern phenomena presuppose a rigorous theory of postmodernity, for which the philosophy of Martin Heidegger holds great untapped promise. This essay explicates the basic content of Heidegger’s “metametaphysics,” since for Heidegger a “metaphysics” is the epochally prevailing projection of the meaning of being in general, and he offers a theory of Western metaphysics. I begin with Heidegger’s analysis of the “regional ontologies” of the sciences in his 1927 magnum opus Being and Time, since (...) the metametaphysical works of the “late middle” Heidegger in the 1930s–1940s extend this analytical framework to metaphysics as global ontology. I then explicate Heidegger’s views on modern metaphysics, focusing on his analyses of modern science and the philosophy of Descartes, before turning to his theory of postmodernity, which I extract from his analyses of modern technology and the philosophy of Nietzsche.

Weather experiences are currently surprisingly under-explored and under-theorised in sociology and sport sociology, despite the importance of weather in both routine, everyday life and in recreational sporting and physical–cultural contexts. To address this lacuna, we examine here the lived experience of weather, including ‘weather work’ and ‘weather learning’, in our specific physical–cultural worlds of distance-running, triathlon and jogging in the United Kingdom. Drawing on a theoretical framework of phenomenological sociology, and the findings from five separate auto/ethnographic projects, we explore the (...) ‘weather-worlds’ and weather work involved in our physical–cultural engagement. In so doing, we address ongoing sport sociological concerns about embodiment and somatic, sensory learning and ways of knowing. We highlight how weather work provides a key example of the phenomenological conceptualisation of the mind–body–world nexus in action, with key findings delineating weather learning across the meteorological seasons that contour our British weather-related training.

The French existentialist philosopher, Simone de Beauvoir, long ago signalled the potentially empowering force of outdoor exercise and recreation for women, drawing on feminist phenomenological perspectives. Feminist phenomenological research in sport and exercise, however, remains relatively scarce, and this article contributes to a small, developing research corpus by employing a feminist phenomenological theoretical framework to analyse lived experiences of running in ‘public’ space. As feminist theorists have argued, such space is gendered and contested, and women’s mobility remains constrained by fears (...) of harassment and violent attack. Running also generates intense pleasure, however, and embodied empowerment. Drawing on findings from two separate but linked automethodological running research projects, here I explore salient and overlapping themes cohering around lived experience of pleasure and danger in both urban and rural spaces.

In this paper we1 assess the potential for research on nonhuman animals to address questions about the phenomenology of painful experiences. Nociception, the basic capacity for sensing noxious stimuli, is widespread in the animal kingdom. Even rel- atively primitive animals such as leeches and sea slugs possess nociceptors, neurons that are functionally specialized for sensing noxious stimuli (Walters 1996). Vertebrate spinal cords play a sophisticated role in processing and modulating nociceptive signals, providing direct control of some motor responses to noxious (...) stimuli, and a basic capacity for Pavlovian and instrumental conditioning (Grau et al. 1990; Grau 2002). Higher brain systems provide additional layers of association, top-down control, and cognition. In humans, at least, these higher brain systems also give rise to the conscious experiences that are characteristic of pain. What can be said about the experiences of other animals who possess nervous systems that are similar but not identical to humans? (shrink)

In order to address sociological concerns with embodiment and learning, in this article we explore the ‘weathering’ body in a currently under-researched physical-cultural domain. Weather experiences, too, are under-explored in sociology, and here we examine in depth the lived experience of weather and, more specifically, ‘weather work’ and ‘weather learning’ in one of the most extreme and corporeally challenging environments on earth: high-altitude mountains. Drawing on a theoretical framework of phenomenological sociology, and an interview-based research project with 19 international, high-altitude (...) mountaineers, we investigate weather as lived and experienced both corporeally and cognitively. We are particularly interested in conceptualizing and theorizing the ways in which embodied beings relate to the environment through different aspects of their being. The novel concepts of ‘weather work’ and ‘weather learning’, we argue, provide salient examples of the mind-body-world nexus at work, as an embodied practice and mode of thinking, strongly contoured by the physical culture of high-altitude mountaineering.

Recent years have seen a burgeoning in phenomenological research on sport, physical cultures and exercise. As editors and reviewers, however, we frequently and consistently see social science articles that claim to be ‘phenomenological’ or to use phenomenology, but the reasons for such claims are not always evident. Indeed, on closer reading, many such claims can often turn out to be highly problematic. At this point, we should clarify that our ‘terrain de sport’ constitutes what has been termed ‘empirical phenomenology’ (Martínková (...) & Parry, 2011) and more specifically from our own ‘home’ discipline, a phenomenologically inspired form of sociology. This latter tradition was developed in North America by Alfred Schütz (1972). By this, we do not mean philosophical phenomenology in all its rich and varied strands, the modern form of which was inspired by Edmund Husserl’s (1913/2002) descriptive and/or transcendental phenomenology. The term itself is derived from the Greek phainomenon, from the root phôs, meaning ‘light’, thus referring to something that is placed in the light, made apparent or shown. Phenomenology is therefore the study of phenomena, things as they present themselves to, and are perceived in consciousness. Importantly, it is not just another form of qualitative research; a point which we discuss later. (shrink)

Legal theorists have characterized physical evidence of brain dysfunction as a double-edged sword, wherein the very quality that reduces the defendant’s responsibility for his transgression could simultaneously increase motivations to punish him by virtue of his apparently increased dangerousness. However, empirical evidence of this pattern has been elusive, perhaps owing to a heavy reliance on singular measures that fail to distinguish between plural, often competing internal motivations for punishment. The present study employed a test of the theorized double-edge pattern using (...) a novel approach designed to separate such motivations. We asked a large sample of participants (N = 330) to render criminal sentencing judgments under varying conditions of the defendant’s mental health status (Healthy, Neurobiological Disorder, Psychological Disorder) and the disorder’s treatability (Treatable, Untreatable). As predicted, neurobiological evidence simultaneously elicited shorter prison sentences (i.e., mitigating) and longer terms of involuntary hospitalization (i.e., aggravating) than equivalent psychological evidence. However, these effects were not well explained by motivations to restore treatable defendants to health or to protect society from dangerous persons but instead by deontological motivations pertaining to the defendant’s level of deservingness and possible obligation to provide medical care. This is the first study of its kind to quantitatively demonstrate the paradoxical effect of neuroscientific trial evidence and raises implications for how such evidence is presented and evaluated.

Wittgenstein famously ended his Tractatus Logico-Philosophicus (Wittgenstein 1922) by writing: "Whereof one cannot speak, one must pass over in silence." (Wovon man nicht sprechen kann, darüber muss man schweigen.) In that earliest work, Wittgenstein gives no clue about whether this aphorism applied to animal minds, or whether he would have included philosophical discussions about animal minds as among those displaying "the most fundamental confusions (of which the whole of philosophy is full)" (1922, TLP 3.324), but given his later writings on (...) language and thought, it seems a plausible hypothesis. Years later he wrote in the Philosophical Investigations (1968, p. 223) another aphoristic statement: "If a lion could speak, we would not understand him." (Wenn der Löwe sprechen könnte, wir könnten ihn nicht verstehen.) Decades of philosophical discussion about what Wittgenstein meant by these remarks illustrate another point: when philosophers speak, we do not fully understand them. (shrink)
