In political philosophy, reflective equilibrium is a standard method used to systematically reconcile intuitive judgments with theoretical principles. In this paper, we propose that survey experiments and a model selection method—i.e., the Akaike Information Criterion (AIC)-based model selection method—can be viewed together as a methodological means of satisfying the epistemic desiderata implicit in reflective equilibrium. To show this, we conduct a survey experiment on two theories of distributive justice, prioritarianism and sufficientarianism. Our experimental test case and AIC-based model selection method (...) demonstrate that the refined sufficientarian principle, a widely accepted principle of distributive justice, is no more plausible than the prioritarian principle. This tells us that some changes of certain intuitions revolving around sufficientarianism should be examined (separately) based on the findings of the survey experiment and AIC model selection. This shows the potential of our approach—both practically and methodologically—as a novel way of applying reflective equilibrium in political philosophy. (shrink)

This paper offers a new insight on the Condorcet Jury Theorem (CJT) in the theory of epistemic democracy. This theorem states that democratic decision-making leads us to correct outcomes under certain assumptions. One key assumption is the ‘independence condition’, which requires that voters form their beliefs independently when they vote. This paper examines the role of an opinion leader as an informational source, which potentially violates independence. We demonstrate that voters’ beliefs may be correlated in the presence of the leader, (...) and that the CJT can fail if the leader’s opinions are reliable. This leads us to the following paradoxical observation: for epistemic democracy, good leaders may be bad, while bad leaders may be good. (shrink)

It is often argued that relational egalitarianism has a fundamental problem with intergenerational justice when compared to other theories of justice such as utilitarianism, prioritarianism, and luck egalitarianism. Recently, Timothy Sommers argued that there is no such comparative disadvantage for relational egalitarianism. His argument is quite modest: it merely aims to reject the claim that there could be no way to extend relational egalitarianism to intergenerational justice. This may be called the ‘No Comparative Disadvantage Thesis’. The present article challenges Sommers’s (...) argument in two ways. First, I show that Sommers fails to provide a reasonable constraint on causal efficacy, which is crucial to his argument for our relation (not relationship) to future generations. Second, I show that the chain-relatedness problem casts a shadow over Sommers’s argument for the No Comparative Disadvantage Thesis. More specifically, compared to the other theories of justice, relational egalitarianism (as it stands) can less easily justify that present persons have duties to future others. This is because relational egalitarianism cannot appeal to a specific principle in regard to the duties in question, because its principle is sensitive to current context and practice. I conclude that the No Comparative Disadvantage Thesis does not hold much promise. (shrink)

The purpose of this paper is to show the plausibility of John Rawls’s treatment of efficiency within the system of justice. While in political philosophy efficiency is often treated as an independent condition for establishing justice, or more precisely, as a necessary condition for establishing justice, Rawls considers efficiency as a non-negligible factor that has normativity in general circumstances. This is similar to the view that efficiency is a presumptive condition for evaluating social arrangements. However, Rawls’s view is salient in (...) a more substantive way. This paper demonstrates the salience of Rawls’s view of efficiency by responding to G. A. Cohen’s Impure Justice Objection to Rawls’s theory of justice. This shows that there is no impure connection between Rawls’s justice and efficiency. Moreover, the combined thesis of Rawls’s justice and efficiency is superior to Cohen’s pluralist theory of justice, making it a fruitful approach. (shrink)

The issue of distributive justice receives substantial amount of attention in our society. On the one hand, we are sensitive to whether and the extent to which people are responsible for being worse off. On the other hand, we are mindful of society’s worst-off members. There has been a debate over luck egalitarianism, which relates to the former concern, and relational egalitarianism, which echoes the latter. By investigating the psychological processes of these two concerns, this paper examines the reliability of (...) the argument that Elizabeth Anderson, a renowned relational egalitarian, presents against luck egalitarianism and for relational egalitarianism. It also considers whether it is possible to support luck egalitarianism and relational egalitarianism simultaneously, using an online experiment. The results of the experiment show that, first, for ordinary people, the luck consideration is as important as the basic capabilities consideration. Second, while real people consider the degree of compensation through the factors of causality and responsibility, the lack of basic capabilities directs them to determine how much victims of bad luck should be compensated. This suggests that pluralist egalitarianism is on the right track. (shrink)

Luck egalitarianism assigns a central role to personal responsibility in egalitarian justice. In the context of healthcare, luck egalitarianism is the view that the distribution of medical and healthcare resources—or common resources in general—should respond to the (im)prudence of individuals. Recently, Joar Björk, Gert Helgesson, and Niklas Juth have argued that it is impractical to use luck egalitarianism as a normative framework in healthcare because it has no reasonable way of dealing with the imprudent. In response to their argument, this (...) paper first suggests that the epistemic problems of applying luck egalitarianism to the healthcare context raised by Björk et al. can be circumvented by using the exemption system as a policy application of luck egalitarian healthcare justice. This paper then shows that an _ex ante_ policy, a tax system with refunds, can reasonably be adopted as a luck egalitarian institutional design of healthcare policy. We argue that the proposed conception of luck egalitarianism can deal with the problem of differential option luck. Finally, we show that the threshold problem for the definition of imprudence does not refute the proposed _ex ante_ policy. (shrink)

In contemporary political philosophy, reflections on poverty demand careful treatment in the light of key ethical concepts—especially autonomy. While the negative effects of poverty on autonomy are acknowledged, the welfare dependency of the poor is seen as an autonomy-undermining factor, which I call the “autonomy–poverty dilemma.” This chapter discusses contemporary political theories about autonomy and poverty in terms of how they relate to this dilemma. The features and problems of three pertinent theories are addressed in such a way as to (...) resolve the autonomy–poverty dilemma. The first is luck egalitarianism, which weighs individual responsibility in defining just distributions, but may leave some of the incapacitated unattended in order not to annul their personal responsibility and may stigmatize those who are dependent (such as people with mental disabilities) who are not personally responsible. Such stigmatization is also a problem with relational egalitarianism, which bases egalitarian justice on the equal standing of individuals, in that the ideal of socially embedded autonomous agents could be degrading to the dependent. While the capability approach overcomes that problem by providing a powerful buttress for the dependent and allowing them to emerge from poverty, it runs the risk of a paternalistic, perfectionist idealism. In closing, this chapter proposes an alternative view, which I call the “radical pluralist view of egalitarian justice,” based on a consideration of the features and problems of these three key theories.

This paper examines whether Kok-Chor Tan’s institutional luck egalitarianism is successful as a pluralist luck egalitarian theory of justice and morality. In recent years, pluralist luck egalitarianism has become a salient theory of justice. Tan’s pluralist proposal for institutional luck egalitarianism is attractive because it seems to refute the metaphysical and practical challenges against luck egalitarianism. This paper demonstrates that, although Tan’s institutional luck egalitarianism is indeed a most sophisticated systematic pluralist theory of justice and morality, his argument fails because (...) the application of luck egalitarianism to the domain of distributive justice and to the basic institutions of society is not justified from the luck egalitarian point of view. This paper concludes that Tan’s institutional luck egalitarianism does not succeed in demonstrating that his theory is an outstanding achievement of luck egalitarianism. (shrink)

This paper argues that the Lockean proviso can be utilized as a relevant principle of justice for food security under global climate change. Since reducing GHG emissions is key to enhancing food security, we suggest a global food security scheme that systematically allots, among all people, access to GHG sinks in food systems impacted by global climate change. For consideration of the scheme, it is important to have a principle of justice. Furthermore, it should incorporate the value of fairness. A (...) relevant principle of climate justice for food security should meet the following criteria: (1) the parties concerned under the scheme are states; (2) fairness does not undermine the requirement that the basic needs of all people must be met; (3) when determining fair burdens, a fair distribution of the rights to use GHG sinks should be sensitive both to each state’s responsibility for its GHG emissions and to (4) each state’s effort to reduce such emissions. With them in mind, first, we argue that the Lockean proviso can provide legitimate guidance for each state. Second, the Lockean proviso reasonably enjoins that a state has a right to a food system that secures its citizens’ basic needs, and a duty to meet the basic needs of other people. Third, the Lockean proviso can be deployed as a principle of both global justice and intergenerational justice for food security. Finally, the Lockean proviso enables us to count the reduction of GHG emissions by each state as “the fruits of its labors”. (shrink)

This article shows that the democratic borders argument is defensible, albeit not in the way Arash Abizadeh proposes. The democratic borders argument depends on the All-Subjected Principle, according to which the exercise of political power is justified only insofar as everyone who is subjected to that power is guaranteed a right to vote. According to the so-called “scope objection,” the scope of the All-Subjected Principle is too broad, however, and therefore, the argument can be refuted by reductio ad absurdum. Here (...) I argue that Abizadeh’s appeal to the narrow-scope interpretation of jurisdictionally circumscribed legal requirements is not a plausible way of defusing this reductio. Instead, I show that the democratic borders argument is successful if the All-Subjected Principle consists of two individually sufficient conditions corresponding to narrow-scope and qualified wide-scope interpretations.

The harshness objection is the most important challenge to luck egalitarianism. Very recently, Andreas Albertsen and Lasse Nielsen provided a scrupulous analysis of the harshness objection and claim that only the inconsistency objection—the objection that luck egalitarianism is incompatible with the ideal of basic moral equality—has real bite. I argue that the relevantly construed incoherence objection is not as strong as Albertsen and Nielsen believe. In doing so, first, I show that the deontological luck egalitarian conception of equal treatment does (...) not endorse harsh policies such as excessive responsibility-sensitive healthcare that would be disrespectful to the imprudent. Second, I demonstrate that deontological luck egalitarianism is not troubled by the case that involves a lack of respect for the prudent, which vexes Anderson’s relational egalitarianism that Kasper Lippert-Rasmussen’s argument highlights. I thus claim that the harshness objection is not a truly decisive objection against the luck egalitarian project. (shrink)

The trolley problem is a classic thought experiment that evokes an ethical dilemma. Thomson’s “bystander” and “footbridge” versions of the trolley problem induce different intuitive judgments about what to choose in the ethical dilemma. However, we can question how robust these intuitive judgments are. We thus conducted an online survey experiment of Thomson’s versions of the trolley problem which showed that more respondents tended to choose not pulling the lever in the bystander version and pushing a person off the bridge (...) in the footbridge version when they believed they were not being watched. These results illustrate that people’s decisions deviate from the social norms in the absence of the public’s attention. To activate the practice of holding the manufacturers to a normative expectation based on the social norms, we suggest the law must be changed. (shrink)

This chapter purports to give empirical feedback on impartial reasoning to justice by using online survey experiments. More precisely, the study focuses on whether and how the different conceptions of the veil of ignorance and John Rawls’s method of reflective equilibrium affect real people’s impartial reasoning to justice. The findings show that, while ordinary people support impartial reasoning to the difference principle (maximin), their endorsement of it echoes neither John Harsanyi’s nor Rawls’s reasoning. The results illuminate that findings in human (...) psychology, such as the principles of loss aversion and “perceived luckiness,” cannot be dismissed for denoting the relevant impartial reasoning to justice.

According to a renowned left-libertarian, Michael Otsuka, a libertarian right of self-ownership can be so robust that one need not sacrifice the use of one's mind and body to help others. In this article, I demonstrate that Otsuka's way of reconciling this robust conception of self-ownership with equality is not appealing and, at best, would provide limited guidance in the face of real-life uncertainty.

First, the author argues that Daniels and Sabin’s way of setting priorities in healthcare is implausible. Daniels and Sanin think there is a lack of consensus on comprehensive principle(s) of justice that can resolve the issue of priority-setting in healthcare. Nevertheless, their argument appeals to the deliberative democracy-based idea of accountability for reasonableness that involve the conception of justice construed naturally as comprehensive. The author then proposes a comprehensive conception of justice, an equal opportunity-based principle of justice, with which the (...) issue of priority-setting can be resolved. Although Daniels addresses two critical issues on the equal opportunity-based principle of justice, the author contends that it can be defended in ways that overcome these issues while being applicable to priority-setting conditions.

This article aims to defend responsibility-sensitive egalitarianism by arguing for the rational capacities-based principle of responsibility as a plausible conception of an agent's responsibility for inequalities caused by his or her choice in responsibility-sensitive egalitarianism. I show that the rational capacities-based principle of responsibility is not only philosophically defensible as a conception of genuine choice, but also promising enough to ward off two common worries which cast doubt on responsibility-sensitive egalitarianism (qua luck egalitarianism): first, the rational capacities-based principle of responsibility (...) allows the assignment of differential degrees of responsibility to rational agents in proportional terms, which may make it echo the adverse effects of their childhood environments. Second, its proportional construal essentially allows that nobody possesses a full degree of rational capacities. This enables responsibility-sensitive egalitarianism to refute the harshness objection. (shrink)

In the Shadow of Justice presents a powerful reconstruction of Anglophone political philosophy. Although the central focus of the book is on the origin and influence of John Rawls's theory of justice, it also uncovers the significance of British political theories in ways that contrast them with the Rawlsian liberal egalitarian idea. The book is, thus, a work of intellectual history that engages with the traditions of normative political theories.By referring extensively to the literature of philosophy, political science, economics, sociology, (...) and the archived materials of Rawls, Katrina Forrester puts forward two provocative theses. First is that the core idea of Rawls's... (shrink)

This paper aims to specify the precise conditions under which an agent is responsible for inequalities. Admittedly, the careful examination of the conditions in question has been the main focus of contemporary egalitarianism. As a matter of fact, contemporary political philosophers take responsibility to be a core conception which in principle justifies inequalities. In particular, they tend to flesh out the conception of responsibility in terms of choice, in such a way that we should hold individuals responsible for chosen inequalities (...) but not for unchosen inequalities. This core idea is intuitively appealing because, on the one hand, alleviation of inequalities that people do not choose would thereby be encouraged, and on the other hand, it avoids an egalitarian ‘moral hazard’: the situation in which people need care nothing for the consequences (economic or otherwise) of their own choice. G. A. Cohen thus goes so far as to say that egalitarianism successfully incorporates “within it the most powerful idea in the arsenal of the anti-egalitarian right: the idea of choice and responsibility.”.

German Idealism was introduced to Japanese intellectuals in the middle of Meiji era and was mainly received from a mystical or religious perspective, as we see in Inoue Tetsujirō’s “harmonious existence,” Inoue Enryō’s “unity of mind and body,” and Kiyozawa Manshi’s “existentialism.” Since these theories envisioned true reality as a unified and living whole, I group them under the label “philosophy of organism” and from (...) there argue that their conviction that “all is truth and truth is all” was shaped in large part by the Awakening of Faith in the Mahayana. The understanding of Buddhist concepts by Meiji philosophers was philosophical in its content, and those who devoted themselves to the study of Western philosophy were encouraged to describe Eastern thought in Western philosophical terms. As a result, the philosophical world of the Meiji era developed an original standpoint that unified Eastern and Western perspectives by means of a logic of “phenomena-in-reality.”. (shrink)

Debates concerning mask wearing continue in Japan. Here we critically examine the reasons for relaxing these regulations from a public health ethics perspective.

AbstractThe Belmont Report continues to be held in high regard, and most bioethical analyses conducted in recent years have presumed that it affects United States federal regulations. However, the assessments of the report’s creators are sharply divided. Understanding the historic reputation of this monumental report is thus crucial. We first recount the historical context surrounding the creation of this report. Subsequently, we review the process involved in developing ethical guidelines and describe the report’s features. Additionally, we analyze the effect of (...) unfolding events on the subsequent creation of federal regulations, especially on gene therapy clinical trials. Moreover, throughout this paper we evaluate the ethical principles outlined in this report and describe how they overlap with the issue of protecting socially vulnerable groups. Based on the analysis, we conclude that the features of the Belmont Report cannot be considered as having affected the basic sections of the federal regulations for ethical reviews that were made uniform in 1981. Nevertheless, regarding the regulations on gene therapy clinical trials—which were at first expected to be applicable to research involving children—in addition to implementing policies regarding the public review of protocols that passed ethical review, this report’s principles are clearly reflected in the key notes that should have been referred to when the report was created.

BackgroundMost medical schools in Japan have incorporated mandatory courses on medical ethics. To this date, however, there is no established means of evaluating medical ethics education in Japan. This study looks 1) To develop a brief, objective method of evaluation for moral sensitivity and reasoning; 2) To conduct a test battery for the PIT and the DIT on medical students who are either currently in school or who have recently graduated (residents); 3) To investigate changes in moral sensitivity and reasoning (...) between school years among medical students and residents.MethodsQuestionnaire survey: Two questionnaires were employed, the Problem Identification Test (PIT) for evaluation of moral sensitivity and a portion of the Defining Issues Test (DIT) for moral reasoning. Subjects consisted of 559 medical school students and 272 residents who recently graduated from the same medical school located in an urban area of Japan.ResultsPIT results showed an increase in moral sensitivity in 4th and 5th year students followed by a decrease in 6th year students and in residents. No change in moral development stage was observed. However, DIT results described a gradual rising shift in moral decision-making concerning euthanasia between school years. No valid correlation was observed between PIT and DIT questionnaires.ConclusionThis study's questionnaire survey, which incorporates both PIT and DIT, could be used as a brief and objective means of evaluating medical students' moral sensitivity and reasoning in Japan.
