The social media industry lacks developed principles of professional ethics that it would need in order to better navigate the ethics of conforming to local media laws in authoritarian countries that lack meaningful protections for privacy, personal and political expression, and intellectual property. This chapter analyzes this question through three frameworks of professional ethics—journalism ethics, technology ethics, and business ethics—and the ways that social media resembles and crucially differs from these three industries.

Contemporary international law separates the international justice of war from the domestic justice of society, but empirically, there is a correlation between democratic governance and military effectiveness, which could have a number of causes. A contemporary reconstruction from _The Seven Military Classics_ of Chinese military philosophy offers potential lessons for how domestic virtues may yield military and geopolitical victory. This chapter reconstructs arguments from the seven treatises into a collective an amalgamated conception of “good governance” that weaves together military strategy (...) and virtue ethics and maintains that good governance at home actually wins wars abroad. A reconstructed classical Chinese conception of “good governance” presents theoretical and ethical challenges, but also offers viable justicial content for contemporary jus ad bellum considerations beyond sovereign self-defense or human rights. It presents a way of instantiating the sprawling conception of human rights that falls short in contemporary discourse. (shrink)

After a regime-changing war, a state often engages in lustration—condemnation and punishment of dangerous, corrupt, or culpable remnants of the previous system—e.g., de-Nazification or the more recent de-Ba’athification in Iraq. This common practice poses an important moral dilemma for liberals because even thoughtful and nuanced lustration involves condemning groups of people, instead of treating each case individually. It also raises important questions about collective agency, group treatment, and rectifying historical injustices. Liberals often oppose lustration because it denies moral individualism and (...) ignores rule of law, and their only justifications for lustration are consequentialist ones. This article suggests that lustration may not necessarily be a problem for liberals. While group treatment might be justified on grounds of convenience and pragmatism in times of transitional justice, there are also valid moral arguments consistent with moral individualism and due process for wholesale group punishment after a war. This article offers four overlapping moral justifications, in a robust defense of the core concept of lustration that is covered by each argument. (shrink)

Non-uniformed combat morally infringes on civilians’ fundamental right to immunity and exacts an impermissible form of unofficial conscription that is morally prohibited even if the civilians knowingly consent to it. It is often argued that revolutionary groups burdened by resource disparities relative to the state or who claim alternative sources of political legitimacy (such as national self-determination or the constitution of a political collective) are justified in using unconventional tactics such as non-uniformed combat. Neither those reasons nor the provision of (...) public goods, however, are sufficient to justify such rights violations and this form of conscription, and it calls into question the suitability of current international legal protections for the non-uniformed.

*North American Society for Social Philosophy (NASSP) Book Award 2019.* -/- *International Studies Association (ISA) - International Ethics Section Book Award 2021.* -/- Although military mores have relied primarily on just war theory, the ethic of cooperation in warfare (ECW)—between enemies even as they are trying to kill each other—is as central to the practice of warfare and to conceptualization of its morality. Neither game theory nor unilateral moral duties (God-given or otherwise) can explain the explicit language of cooperation in (...) developing and enforcing principles of military ethics and the law of armed conflict. -/- The ethic of cooperation is borne of various motivations: reciprocity, self-preservation, and efficiency, to be sure, but also a sense of warrior honor and concern with human rights. This shared morality can persist despite making it more difficult for one side or the other to win and, unfortunately, its well-meaning motivations often lead to unintended tragic consequences. -/- This book explores three manifestations of this significant yet overlooked ethic of cooperation in warfare: (1) for a “fair fight,” (2) to protect classes of individuals (e.g., non-combatants or prisoners of war), and (3) to end the war quickly. Such cooperation can take unexpected forms, from ad hoc decisions on the battlefield to institutionalization in international law, and is the source of some critical tensions in one of the most significant developments in warfare in recent years: namely, how to handle terrorism or other forms of warfare that lie outside the purview of international law. -/- Each type of ECW raises questions internal to that ethic, such as inconsistencies in the concept of “parity” across different weapons bans, contradictions within the warrior ethic that heavily influence—and therefore confuse—notions of the “fair fight,” the disconnect between what protections a person receives and his responsibility for the war (e.g., political leaders), or the limited decisiveness of outcomes generated by very short wars. -/- Their simultaneous application also generates significant tensions and raises questions about the proper relationship of ECW to the immediate goal of war itself, which is to win, and thus yield either a political settlement or a justicial decision. For example, the ECWs for a “fair fight” and to protect classes of individuals can make it harder to win the war, but even more concerning is that they can also kill more people, which in the latter case contravenes its very purpose. -/- Human history is in some ways the story of trying to concurrently wage and tame war, and the architecture of warfare itself is informed by the ECW, in particular: (a) the political nature of war, (b) the abdication from jus ad bellum judgments in order to concentrate on justice within war (jus in bello), and (c) the ways in which modern nation-states collude to define “legitimacy” in war. -/- The combination of these three features leave questions of justicial right and responsibility for war disturbingly unresolved, it also generates new challenges in a geopolitical context in which cooperative and non-cooperative (e.g. contemporary terrorism) forms of warfare clash.

The presence and absence of autonomy in Joseph Chan’s democratic Confucianism loom large, but not always in the ways that he maintains. Although Chan claims that his reconstruction of Confucianism for modern democracy can accept some forms of moral autonomy, what he presents does not constitute genuine moral autonomy, and the absence of that autonomy sits in tension with some other aspects of his model. When it comes to personal autonomy, it is the opposite: Chan says that the exercise of (...) personal autonomy can be part of a life well-lived but is not strictly necessary and can be outweighed by perfectionist considerations of well-being and ethics; however, his model incorporates and relies on the exercise of personal autonomy and leaves room for its intrinsic value.

A religion with Buddhism's particular moral philosophies of non-violence and asceticism and with its *functional* polytheism in practice should not generate genocidal nationalist violence. Yet, there are resources within the Buddhist canon that people can draw from to justify violence in defense of the religion and of a Buddhist-based polity. When those resources are exploited, for example in the context of particular Theravāda Buddhist practices and the history of Buddhism and Buddhist identity in Burma from ancient times through its colonial (...) and contemporary periods, it perpetuates an ongoing tragedy that is less about religion than about ethno-nationalism.

In *Against Political Equality: The Confucian Case*, BAI Tongdong says that his main target is democracy, but he focuses much of his critiques on liberalism, rejecting its foundational value of autonomy in favor of Confucian grounds for governance. Given the extent of his concurrence with liberalism, however, it would be more consistent with Bai’s stated aim (of tempering the democratic part and shoring up the liberal side of liberal democracy) to make common cause with liberalism against populism. Mencian compassion and (...) humaneness have much to add to liberal conversation about virtue, and a Mencian-liberal theory of governance, instead, could yield the Confucian ideal of ‘harmony without uniformity,’.

With the stunning spread of democracy over large swathes of the globe since 1975 seemingly coming to a halt and perhaps receding in recent years, we revisit the question of whether democracy is really compatible with all types of cultures and philosophies, particularly those from Asia, where nearly two-thirds of the world’s population lives. Joseph Chan’s *Confucian Perfectionism: A Political Philosophy for Modern Times* (Princeton University Press, 2014) reconstructs Confucianism in order to meld it with democracy in a mutually advantageous (...) marriage. Democracy can address the dangerous problem of the lack of accountability — the historical record is quite clear about what happens when rulers, even those who are wise and well-meaning, are unconstrained. This, unfortunately, is a problem that Confucianism shares. On the other hand, Confucianism can bring to the table not just virtues in general, but particular virtues that are often sadly lacking and sorely needed in democratic politics such as civility, benevolence, integrity, knowledge, and honesty.

Although there is no more iconic, stalwart, and eloquent defender of liberty and representative democracy than J.S. Mill, he sometimes endorses non-democratic forms of governance. This article explains the reasons behind this seeming aberration and shows that Mill actually has complex and nuanced views of the transition from non-democratic to democratic government, including the comprehensive and parallel material, cultural, institutional, and character reforms that must occur, and the mechanism by which they will be enacted. Namely, an enlightened despot must cultivate (...) democratic virtues such as obedience, industriousness, spirit of nationality, and resistance to tyranny in the population and simultaneously prepare the way for his own demise and secure his own legitimacy by transitioning to the rule of law. This challenges recent scholarship that paints Mill’s non-democratic views as crudely and uncritically imperialist, because it fails to recognize and engage seriously with his sophisticated (if ultimately problematic) theory of individual and institutional development under enlightened colonialism.

Clausewitz made the intuitively appealing claim that wars tend to “absoluteness,” and that all limitations imposed by law and morality are in theory alien to it. Clausewitz of course knew that there are in practice many limitations to how wars are fought, but he saw them as contingent to what war is. Since then, however, historians such as John Lynn (Battle: A History of Combat and Culture [Westview Press, 2003]), John Keegan (A History of Warfare ([Random House,1993]) and Victor Davis (...) Hanson (The Western Way of War [Oxford University Press, 1989]) have taught us to see things differently: war is a cultural phenomenon, and the limitations that rituals and taboos impose are essential to what war is. With Conspiring with the Enemy, her intelligent and erudite book on cooperation in war, Yvonne Chiu builds on that work by showing the wide variety of forms cooperation in war can take—something that, Chiu claims, we tend to overlook and take for granted at the same time.

In a recent article Yvonne Chiu argues that nonuniformed combat is impermissible. However, her argument that by fighting without uniforms nonuniformed guerillas coerce civilians into participating in the armed conflict and thus into surrendering their immunity (their right not to be attacked) fails: there is no coercion, no participation, and no surrendering of immunity. Yet even if this argument of hers were correct, it would still not show that such “coercion” would amount to a rights infringement. Moreover, even (...) if it did, there are examples that show that such an infringement would sometimes be perfectly justified. Finally, if she were right that forcing civilians into a moral position that they have not accepted or chosen is absolutely wrong, then this would affect the moral status of uniformed combatants no less than it would affect the moral status of nonuniformed ones.

In this paper, we explore the concept of virtue in nursing care. We particularly examine the description of ‘virtue’ offered by Aristotle, who considers it the mental constitution that forms the basis for laudable social behaviour. We then turn to Katie Eriksson's work on caritative caring ethics and draw parallels between the Aristotelian concept of virtue and being a good nurse. Eriksson suggests that embracing an ethos, a set of basic values, affects nurses’ attitudes as well as the way they (...) speak and take on their responsibility for the patient. We discuss these ideas in relation to a tentative ideal model of the movement from ethos to action to understand and address nurses’ ethical thinking and acting. Here, we focus on the catalytic role of virtue as a means for realizing a deliberate, intentional acting with the best of the patient in mind. As an outcome of our analysis, we suggest that the movement of virtue from ethos to action is most usefully conceptualized as knowledge about facts, habits of the heart, deeds of the hand and the power of words. Implications for nursing leadership are suggested, including incorporating organizational values through the means of ethical conversations. (shrink)

In 2009, with the enactment of the Lisbon Treaty, the Charter of Fundamental Rights of the European Union entered into force. Under Article 8 of the Charter, for the first time, a stand-alone fundamental right to data protection was declared. The creation of this right, standing as a distinct right to the right to privacy, is undoubtedly significant, and it is unique to the European legal order, being absent from other international human rights instruments. This commentary examines the parameters of (...) this new right to data protection, asking what are the principles underpinning the right. It argues that the right reflects some key values inherent in the European legal order, namely: privacy, transparency, autonomy and nondiscrimination. It also analyses some of the challenges in implementing this right in an era of ubiquitous veillance practices and Big Data. (shrink)

This study focuses on the cultural context of ethical decision making by considering the relationship between power distance and ethical judgment. Specifically, we propose that this relationship exists because of the influence of peers on ethical judgment and perceptions of justice. Considering the importance of peers in stage three of Kohlberg's model of moral development, we argue that peers are the basis for social comparisons, social cues and social identification and, hence, are critical to an individual's beliefs about justice. Using (...) scenarios developed by Reidenbach and Robin, data were collected from German and Italian graduate business students. Germany and Italy differ substantially in power distance, but not in the three other cultural dimensions of Hofstede. Results show that the ethical assessment of the respondents from the two countries differs when justice criteria are used. Theoretical and practical implications of the results are discussed.

Objectives: Initially, we analyzed relations between the challenging working conditions of flight attendants with symptoms of depression, anxiety and stress. As the COVID-19 pandemic plunged airlines into an unprecedented crisis, its impact on the mental health of flying cabin crews became the focus of a second survey.Methods: Flight attendants were surveyed online with DASS-21 in May 2019 and April 2020, complemented with questions about working conditions and existential fears and fear of job loss.Results: Sample 1 revealed that symptoms of depression, (...) anxiety and stress highly correlated with the subjective assessment of working conditions, but not with objectifiable parameters. Sample 2 showed significant positive correlations between existential fears and fear of job loss with depression, anxiety and stress. Crew members, grounded in April 2020, showed significantly higher scores in depression and stress, while still flying individuals had more clinically relevant symptoms of anxiety. Mean value comparisons between sample 1 and 2 in DASS-21 revealed a significant increase in symptoms at the time of crisis with effect sizes of d = 0.63 for depression, d = 0.26 for anxiety, and d = 0.52 for stress. The incidence of clinically relevant symptoms among the respondents increased from 8 to 23%, from 6 to 14%, and from 8 to 24%.Conclusion: The COVID-19 pandemic and associated work restrictions coincide with severe impairment of mental health of flying cabin crews, consistent with a mental health protecting function of labor.

Background:Within nursing, the concepts of home and homelike have been used indiscriminately to describe characteristics of healthcare settings that resemble a home more than an institution.Objectives:The aim of this study was to investigate the concept of home. The main questions were as follows: What does the concept of home entail etymologically and semantically? Of what significance is the meaning of the concept to caring science and nursing?Design and methods:This study had a qualitative design with a hermeneutical approach guided by Gadamer. (...) Eriksson’s model of concept determination was partly used to determine the etymology and semantics, the essence and epistemic category of the concept of home. In this study, etymological dictionaries and 17 Swedish language dictionaries published between 1850 and 2001 were investigated.Ethical consideration:In all parts of this study, ethical guidelines have been followed concerning both gathering data from dictionaries and other sources and during the interpretation of these sources.Findings:The home, framed as the ethos of caring, can be drawn as a three-dimensional picture where the three dimensions have a common core, enclosed and inviolable. Symbolically, the picture of home can be seen as the ethos of the human being’s innermost room, the human being’s manner of being and the tone expressed in the external or abstract room where the human being lives and interacts with others.Conclusion:Based on the findings in this study, we conclude that home as ethos is an inner ethical dimension within the human being. Human beings who are in contact with their ethos, the self, feel at home and dare to follow the voice of their heart. Nurses who experience at-homeness have an ability to invite the patient into a caring relationship. The home and the feeling of being at home have significant meaning in terms of human beings’ health and well-being. (shrink)

The Finnish nursing theorist Katie Eriksson's (1943–2019) theory of caritative caring represents a non‐medical paradigm concerning the phenomena of nursing. The aim of this article was to present an oversight of the development of Eriksson's theory of caritative caring from a human science point of view. The historical development of the theory is outlined, combined with a brief overview of its philosophical connections, its impact on contemporary caring science research and its implications for nursing care. Caring science is considered a (...) human science in the Nordic tradition, as it is deeply rooted in basic issues of human life and existence. The key ideas of Eriksson's theory of caritative caring are linked to the metaparadigm concepts of human being, health and suffering, caring and environment. All of these are permeated with the ethos of caritative caring, that is, the caritas thought of human love and mercy, and the honouring of the absolute dignity of human beings. Epistemologically, Gadamer is the most influential philosopher when it comes to the theory of caritative caring. Eriksson's theory is used in, for example, intercultural caring, caring for patients suffering from addiction, the importance of aesthetic surroundings, providing ethically good care for older people and mothers as patients in psychiatric care. In these fields of research, Eriksson's ideas of ethics, caring and suffering are highlighted in various clinical contexts. Beyond the areas of nursing care in which Eriksson's work has been cited and developed, there are at least two areas that have been actively enhanced by her works: the field of leadership and education for nursing teachers. According to Eriksson, it is momentous to ponder scientific results as not limited to empirically strengthened, randomized outcomes. Part of making the results of scientific work evident is up to the individual nurses and their being in the world. (shrink)

In this book, an international group of philosophers, economists and theologians focus on the relationship between justice, luck and responsibility in health care. Together, they offer a thorough reflection on questions such as: How should we understand justice in health care? Why are health care interests so important that they deserve special protection? How should we value health? What are its functions and do these make it different from other goods? Furthermore, how much equality should there be? Which inequalities in (...) health and health care are unfair and which are simply unfortunate? Which matters of health care belong to the domain of justice, and which to the domain of charity? And to what extent should we allow personal responsibility to play a role in allocating health care services and resources, or in distributing the costs? With this book, the editors meet a double objective. First, they provide a comprehensive philosophical framework for understanding the concepts of justice, luck and responsibility in contemporary health care; and secondly, they explore whether these concepts have practical force to guide normative discussions in specific contexts of health care such as prevention of infectious diseases or in matters of reproductive technology. Particular and extensive attention is paid to issues regarding end-of-life care. (shrink)

Women generally initiate, lead, and constitute the rank and file of environmental justice activism. However, there is little research on why there are comparatively so few men involved in these movements. Using the environmental justice movement in the Central Appalachian coalfields as a case study, we examine the ways that environmental justice activism is gendered, with a focus on how women’s and men’s identities both shape and constrain their involvement in gendered ways. The analysis relies on 20 interviews with women (...) and men grassroots activists working for environmental justice in the coalfields of Appalachia. We find that women draw on their identities as “mothers” and “Appalachians” to justify their activism, while the hegemonic masculinity of the region, which is tied to the coal industry, has the opposite effect on men, deterring their movement involvement. We explore the implications of these findings for understanding the relationship of gender to environmental justice activism. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 22 (2002) 149-162 [Access article in PDF] Buddhist-Christian Complementarity in the Perspective of Quantum Physics Lai Pan-chiu Chinese University of Hong Kong Introduction The idea of Buddhist-Christian complementarity is by no means new. 1 But what is meant by "complementarity"? In quantum physics, the concept of "complementarity" has been extensively discussed due to the principle of complementarity introduced by Niels Bohr (1885-1962). This principle is also (...) one of the hotly debated issues in the areas of religion and natural science. Many scholars attempt to show that there are cases in Christian theology comparable to the complementarity in quantum physics. The most discussed case is perhaps the Christological doctrine of two natures in Jesus Christ. 2 Some scholars even attempt to interpret the relationship between theology and science in terms of complementarity. 3 This kind of discussion is not merely fanciful imagination originated by Christian theologians, since even Niels Bohr himself did advise Christian theologians to apply the complementary way of thinking in theology. 4 An interesting question may then be whether the principle of complementarity in quantum physics may cast light on the problem concerning Buddhist-Christian complementarity. This is the issue this essay attempts to address. Complementarity in Quantum Physics Modern physics, especially the theory of relativity and quantum physics, as Werner Heisenberg pointed out, brings forth to us an important philosophical issue—the relationship between language and reality. Some modern physicists find that they have to make use of ordinary language to establish a visual understanding or presentation of some events, which can hitherto only be expressed by a bundle of mathematical formulae. However, the ordinary language, together with its derived concepts, used in classical physics cannot adequately interpret some of the discoveries of modern physics. For example, conventional concepts of time and space can no longer apply directly in the general theory of relativity. The inadequacy of the classical concepts of "wave" and "particle" in quantum physics is another illustrative case. According to Bohr's theory, physicists can make use of these classical concepts in a [End Page 149] loose way, even though these concepts may seem to contradict each other when applied together. 5The principle of complementarity proposed by Niels Bohr refers specifically to the use of the two seemingly contradictory concepts in classical physics—"particle" and "wave"—to explain the behavior of a particular entity, light. Wave and particle are mutually exclusive concepts in classical physics. According to the classical understanding, wave possesses some characteristics that particle does not have, such as reflection, refraction, diffusion and interference. In reverse, particle also possesses some characteristics that wave does not have, such as occupying certain space. However, quantum physicists have discovered that in some experiments, light "behaves" as wave, whereas in others it behaves as particle. The results of experiments seem to suggest that neither "wave" nor "particle" can adequately explain the quantum phenomena. For this reason, some physicists, including Albert Einstein, suggest abandoning the use of the concepts of wave and particle in the subatomic realm. Contrary to this view, Bohr insists that the concepts of "wave" and "particle" remain usable and useful in quantum physics because "however far the phenomena transcend the scope of classical physical explanation, the account of all evidence must be expressed in classical terms." 6 As Bohr puts it, "the fundamental postulate of the indivisibility of the quantum of action is itself, from the classical point of view, an irrational element which inevitably requires us to forego a causal mode of description and which, because of the coupling between phenomena and their observation, forces us to adopt a new mode of description designated as complementary in the sense that any given application of classical concepts precludes the simultaneous use of other classical concepts which in a different connection are equally necessary for the elucidation of the phenomena." 7The principle of complementarity can thus be understood as a method or "mode of description" using two or more mutually exclusive concepts of a specific realm (classical physics) to explain a phenomenon of another realm (quantum physics) that...
