Determining the relationship between the entire brain structure and individual differences is important in extending healthy life expectancy, which can be affected by brain atrophy. The entire brain structure has been gradually known to be correlated not only with age but also with individual differences, such as quality of life, general intelligence, and lifestyle. However, little attention has been paid to the relationship between the entire brain structure and personal traits. We herein focused on one personal trait, namely spiritual growth, (...) and examined its relationship with the entire brain structure using two neuroimaging-derived measures, namely the gray matter Brain Healthcare Quotient, a measure of GM volume, and the fractional anisotropy Brain Healthcare Quotient, a measure of white matter integrity, in 229 healthy participants. The results indicated no significant relationship between the GM-BHQ and spiritual growth, but there was a significant positive correlation between the FA-BHQ and spiritual growth after controlling for age, sex, and body mass index with partial correlation analysis. Furthermore, multiple regression analysis revealed a significant positive correlation between the FA-BHQ and spiritual growth after controlling for physical characteristics, such as age, sex, and BMI, as well as other variables related to lifestyle that were collected using the Health-Promoting Lifestyle Profile. These results support the idea that there is a relationship between the entire WM brain structure and spiritual growth. Further studies are required to clarify the causal relationship between the entire WM brain structure and spiritual growth with some interventions to improve spiritual growth. Such studies will help extend healthy life expectancy from a new perspective of personal trait. (shrink)

We introduce the Easton collapse and show that the two-stage iteration of Easton collapses gives a model in which the successor of a regular cardinal carries a strongly saturated filter. This allows one to get a model in which many successor cardinals carry saturated filters just by iterating Easton collapses.

The Japanese Transplantation Law is unique among others in that it allows us to choose between "brain death" and "traditional death" as our death. In every country 20 to 40 % of the popularion doubts the idea of brain death. This paper reconsiders the concept, and reports the ongoing rivision process of the current law. Published in Hastings Center Report, 2001.

Shweder et al. (1997) proposed the three domains of morality: Autonomy, Community, and Divinity. This study used situation sampling to explore how people from Japan and the U.S. interpret moral transgressions provided in their own and another cultural context. Specifically, the analysis tested whether participants with one cultural background recognize culturally congruent moral transgressions as violations more frequently and feel more harshly towards them than culturally incongruent domains. Furthermore, the extent of evocation caused by the home and another culture was (...) investigated. This study asked 102 Japanese and 168 U.S. participants to judge which domain would be primarily involved in each transgression and to rate their wrongness. Participants showed a higher perceived magnitude of transgressions in culturally valued domains provided by in-group than outside members. Cross-cultural differences in morality and future directions are discussed. (shrink)

In his “A new argument for evidentialism” (Shah, Philos Q 56(225): 481–498, 2006 ), Nishi Shah argues that the best explanation of a feature of deliberation whether to believe that p which he calls transparency entails that only evidence can be reason to believe that p. I show that his argument fails because a crucial lemma that his argument appeals to cannot be supported without assuming evidentialism to be true in the first place.

One prominent feature of belief is that a belief cannot be formed at will. This paper argues that the best explanation of this fact is that belief formation is a process that takes aim at the truth. Taking aim at the truth is to be understood as causal responsiveness of the processes constituting belief formation to what facilitates achieving true beliefs. The requirement for this responsiveness precludes the possibility of belief formation responding to intentions in a way that would count (...) as forming a belief at will. (shrink)

The aim of this paper is to propose a new approach to the question of meaning in life by criticizing Thaddeus Metz’s objectivist theory in his book Meaning in Life: An Analytic Study. I propose the concept of “the heart of meaning in life,” which alone can answer the question, “Alas, does my life like this have any meaning at all?” and I demonstrate that “the heart of meaning in life” cannot be compared, in principle, with other people’s meaning in (...) life. The answer to the question of “the heart of meaning in life” ought to have two values, yes-or-no, and there is no ambiguous gray zone between them. I believe that this concept constitutes the very central content of meaning in life. (shrink)

We give a model of set theory in which the strongly non‐stationary ideal over is weakly presaturated below some canonical set. Here μ is a regular uncountable cardinal. The model is the forcing extension with the Lévy collapse of a Woodin cardinal to the successor of μ. This improves on results of Goldring and of the first author.

語ることによって出来事は過去になり、また現在になる。大災害に直面した人は、その極限状態をどのように記憶し、記録してゆくのか。震災や戦争、原発事故などを例に、博物館や語り、モニュメントや場といった形を介 してカタストロフが時間を渡っていくさまを描き出す。.

The objective of this paper is to contribute to the international discussions on life and scientific technology by examining the images and concepts of life in contemporary Japan. In English the word Inochi can be rendered as "life". However, the nuances of the Japanese term differ in certain cases, and therefore I have chosen to use the term much as is. I first discuss the linguistic meanings of the word, and then consider several important features of the images of inochi (...) that have appeared in publications and responses from questionnaires on this topic. Some philosophical and metaphysical interpretations of the concept of inochi are then proposed. Finally a brief outline of the study of life is presented, suggesting a new way to approach bioethics and discussions on environmental issues. This paper is a republication of Morioka (1991) in "Japan Review" under the permission of "Japan Review" and "Global Bioethics.". (shrink)

We give an extender characterization of a very strong elementary embedding between transitive models of set theory, whose existence is known as the axiom I2. As an application, we show that the positive solution of a partition problem raised by Magidor would refute it.

Many cultures have had knowledge imposed from outside, whether by force or for reasons of power, to the detriment of their own endogenous knowledge and the wisdom developed throughout their history. Would Japan’s acquisition of Western knowledge have led but to the development of a lesser know-how, devoid of meaning or sense, or even of knowledge which it might be better to ignore? Far from benefiting from an endogenous development or a modernization respectful of beings and of their environment, the (...) developing countries that superficially adopt this unilateral knowledge undergo a type of ‘self-colonization’. Although concurring with biologist Keiko Nakamura’s theory that scientific attitudes must be studied from within, Masahiro Hamashita considers that knowledge from outside allows for more solid internal reflection. He thus advocates the development of an integrated, hybrid knowledge, where external knowledge is mixed with internal knowledge in a spontaneous, harmonious way, as was the case with the traditional knowledge that Japan acquired from China.

Is, or has, democracy a universal value? This is the main question raised by this paper, which distinguishes between two aspects of democracy: political institution in opposition to despotism, and political belief against any kind of slavery and subordination. The role played by intellectuals in the development of contemporary democracy, and the relation of democracy to mass culture and the influence of mass media on a true democratic attitude, are studied within the frame of an overall 'mass aesthetization' which characterizes (...) contemporary societies.
