Human space exploration requires massive budgets every fiscal year. Especially under severe financial constraint conditions, governments are forced to justify to society why spending so much tax revenue for human space exploration is worth the cost. The value of human space exploration might be estimated in many ways, but its social significance and cost-effectiveness are two key ways to gauge that worth. Since these measures should be applied country by country because sociopolitical conditions differ in each country and must be (...) taken into consideration, the study on the social significance of human space exploration must take the coloration of a case-study. This paper, focusing on the case of Japan with surveying Japanese literary and national documents as well as taking its sociopolitical conditions into account, examines the social significance of human space exploration. -/- First, we give an overview of the circumstances surrounding Japan's human space exploration program. Derived from the statements of such relevant parties as scholars, journalists, policy makers, and astronauts, this overview indicates that the main concerns about human space exploration in Japan are its social significance and cost-effectiveness (Section 1). Next, an overview of behavioral science—an essential field for human space exploration (referred to in this paper as space behavioral science) that provides support for astronauts—is presented from the perspective of stress research in isolated and confined environments (Section 2). We then give two examples of where such knowledge from space behavioral science research has been applied to terrestrial isolated and confined environments. One is JAXA’s support in 2009 for people who were vulnerable to infection by a new strain of flu and accordingly placed in an isolated and confined facility under the Infectious Disease Law and the Quarantine Law. The other is NASA's support in 2010 for Chilean mine workers who were trapped 700 m underground after a mining accident (Section 3). Based on these case studies, we illustrate the further social utility of such knowledge through a discussion of potential applications in other situations in Japan. Focusing on Japan for its geographical and social features in being an earthquake-prone archipelago and having the world's preeminent aging society, we show that refugees living in evacuation centers and people in an elderly-elderly homecare situation pose socially problematic situations specific to Japan. We then argue that space behavioral scientific knowledge can be applied to support people under these and other isolated and confined environments in various ways (Section 4). Finally, we demonstrate that such an application can be understood as an ethical contribution to Japanese society and that this contribution can be embedded in Japan's space policy (Section 5). We conclude that human space exploration can be a socially significant and cost-effective endeavor that is worthy of tax revenue expenditures because space behavioral science is highly likely to provide unique and useful knowledge to help address various social problems concerning terrestrial isolated and confined environments and support people in sufferings there.

明治の世には、西欧的近代化の流れの中にあっても「日本人としての矜持と風格」といったものがあった。それはいわば凜乎とした倫理意識と、土着的な共同体意識である。それらは漢籍の教養に裏打ちされた至高なる精神 性であったと言ってよい。明治は、思想・文化の面において、日本の精神史上、「豊饒の時代」であった。.

Possible worlds have revolutionised philosophy and some related fields. But, in recent years, tools based on possible worlds have been found to be limited in many respects. Impossible worlds have been introduced to overcome these limitations. This Element aims to raise and answer the neglected question of what is characteristically impossible about impossible worlds. The Element sheds new light on the nature of impossible worlds. It also aims to analyse the main features and utility of impossible worlds and examine how (...) impossible worlds can capture distinctions which are unavailable if we limit ourselves to possible world-based tools.

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)

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.

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)

A dialectical contradiction can be appropriately described within the framework of classical formal logic. It is in harmony with the law of noncontradiction. According to our definition, two theories make up a dialectical contradiction if each of them is consistent and their union is inconsistent. It can happen that each of these two theories has an intended model. Plenty of examples are to be found in the history of science.

朝鮮史上最も偉大な思想家とされる李退渓(イテゲェ)(1501-70)の知られざる素顔と数々の「謎」を解明する画期的研究。.

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)
