戦後の進歩的知識人の代表、思想史学のリーダーであった丸山真男。超国家主義、「原型」・「古層」を追究し、山崎闇斎学派、荻生徂徠、福沢諭吉らの思想構造を解明する丸山思想史学を再構成。丸山に対する論評を詳述 。.

We discuss a propositional logic which combines classical reasoning with constructive reasoning, i.e., intuitionistic logic augmented with a class of propositional variables for which we postulate the decidability property. We call it intuitionistic logic with classical atoms. We introduce two hypersequent calculi for this logic. Our main results presented here are cut-elimination with the subformula property for the calculi. As corollaries, we show decidability, an extended form of the disjunction property, the existence of embedding into an intuitionistic modal logic and (...) a partial form of interpolation. (shrink)

The Paradox of the Knower was originally presented by Kaplan and Montague [26] as a puzzle about the everyday notion of knowledge in the face of self-reference. The paradox shows that any theory extending Robinson arithmetic with a predicate K satisfying the factivity axiom K → A as well as a few other epistemically plausible principles is inconsistent. After surveying the background of the paradox, we will focus on a recent debate about the role of epistemic closure principles in the (...) Knower. We will suggest this debate sheds new light on the concept of knowledge which is at issue in the paradox – i.e. is it a “thin” notion divorced from concepts such as evidence or justification, or is it a “thick” notion more closely resembling mathematical provability? We will argue that a number of features of the paradox suggest that the latter option is more plausible. Along the way, we will provide a reconstruction of the paradox using a quantified extension of Artemovʼs [2] Logic of Proofs, as well as a series of results linking the original formulation of the paradox to reflection principles for formal arithmetic. On this basis, we will argue that while the Knower can be understood to motivate a distinction between levels of knowledge, it does not provide a rationale for recognizing a uniform hierarchy of knowledge predicates in the manner suggested by Anderson.

This paper considers the boundary that separates marketable from non-marketable items. First, it examines the issue of blocked exchanges, that is, exchanges that cannot and/or should not take place. Second, it proposes to synthesise the seemingly separate issues of blocked exchanges from a single perspective based on critical realist ontology. Finally, it tackles some scepticism and criticism that has been levelled against the idea that ontology can be useful in determining a market boundary.

While the complexities of interpreting in constrained legal contexts such as trials may gradually be getting better understood by legal professionals, the particular difficulties of interpreting for the Deaf remain largely overlooked, and the recent involvement of citizen judges in Japan’s justice system makes it even more important to raise awareness about this aspect of language disadvantage. This paper focuses on a key feature of Japanese Sign Language: the non-manual markers produced by facial and body movements that accompany hand and (...) finger signs. Research shows such markers to be poorly understood by non-Deaf observers and indeed even sign language interpreters sometimes conflate them with gestures used by hearing people. (shrink)

The sophisticated function of the central nervous system (CNS) is largely supported by proper interactions between neural cells and blood vessels. Accumulating evidence has demonstrated that neurons and glial cells support the formation of blood vessels, which in turn, act as migratory scaffolds for these cell types. Neural progenitors are also involved in the regulation of blood vessel formation. This mutual interaction between neural cells and blood vessels is elegantly controlled by several chemokines, growth factors, extracellular matrix, and adhesion molecules (...) such as integrins. Recent research has revealed that newly migrating cell types along blood vessels repel other preexisting migrating cell types, causing them to detach from the blood vessels. In this review, we discuss vascular formation and cell migration, particularly during development. Moreover, we discuss how the crosstalk between blood vessels and neurons and glial cells could be related to neurodevelopmental disorders. (shrink)

Background: The present study compared the effects of a traditional resistance training and resistance training combined with cognitive task on body composition, physical performance, cognitive function, and plasma brain-derived neurotrophic factor levels in older adults. Methods: Thirty community-dwelling older adults were randomized into TRT and RT+CT. Exercise groups performed a similar resistance training program, twice a week over 16 weeks. Cognitive Training involved performing verbal fluency simultaneously with RT. Exercise sessions were performed 2-3 sets, 8-15 repetitions at 60-70% of 1-repetition (...) maximum. Body composition, physical function, cognitive performance, and BDNF levels were assessed before and after intervention period. Results: The physical performance was similarly improved in response to both TRT and RT+CT. However, exclusive improvements on cognitive function and BDNF levels were observed only after RT+CT. Conclusion: The RT program associated with a cognitive task, improved physical and cognitive performance in healthy older adults. (shrink)

The members of the Six gene family were identified as homologues of Drosophila sine oculis which is essential for compound-eye formation. The Six proteins are characterized by the Six domain and the Six-type homeodomain, both of which are essential for specific DNA binding and for cooperative interactions with Eya proteins. Mammals possess six Six genes which can be subdivided into three subclasses, and mutations of Six genes have been identified in human genetic disorders. Characterization of Six genes from various animal (...) phyla revealed the antiquity of this gene family and roles of its members in several different developmental contexts. Some members retain conserved roles as components of the Pax-Six-Eya-Dach regulatory network, which may have been established in the common ancestor of all bilaterians as a toolbox controlling cell proliferation and cell movement during embryogenesis. Gene duplications and cis-regulatory changes may have provided a basis for diverse functions of Six genes in different animal lineages. (shrink)

A 2012 review article for Metascience which explains Mach's realistic brand of empiricism, contrasting it with the common phenomenalist reading of Mach by John Blackmore in two recent books.

In his project of going beyond the “modern worldview,” Hiromatsu Wataru attached great importance to Ernst Mach’s philosophical thought and Einstein’s theory of relativity as challenging the premises of modern philosophy, which he characterized as substantialist and bound by the subject / object schema. This paper surveys Hiromatsu’s analysis of Mach’s phenomenalist element-monism, specifically his critique of Mach’s insufficient break with modern philosophy; his inquiry into Einstein’s relativity theory with a focus on its intersubjective cognitive structure; and the way he (...) extends his views on these themes to a general ontological-epistemological theory of the “fourfold structure.” Finally, it examines questions about Hiromatsu’s arguments regarding the tension between the dimensions of synchronic structure and structuring movement. An earlier version of this paper can be found as “Philosophers” in John T. Blackmore, Itagaki Ryōichi, and Tanaka Setsuko, eds., Ernst Mach’s Influence Spreads, 425–76. (shrink)

How are the teachings of a thirteenth-century master relevant today? Twenty contemporary writers unpack Dogen's words and show how we can still find meaning in his teachings. Engaging Dogen's Zen is a practice oriented study of Shushogi (a canonical distillation of Dogen's thought used as a primer in the Soto School of Zen) and Fukanzazengi (Dogen's essential text on the practice of "just sitting," a text recited daily in the Soto School of Zen). It is also a study of the (...) entire self. Here, the principles of Soto Zen practice are unpacked and explained by leading contemporary Buddhists from the living tradition--monks, priests, academics, and community teachers. Tackling Dogen's approach to key issues, such as the preeminence of shikantaza, universal buddha nature, and what it means to be a Mahayana Buddhist, the contributors to the volume help Zen practitioners and any who are trying to deepen their lives to appreciate better the teachings of Soto Zen and make these teachings part of their lives. By revisiting what remains precious in Shushogi and Fukanzazengi, we let them breathe just as we learn to breathe in zazen. We find that Soto practice not only engages Dogen and Sakyamuni, but all of our sisters and brothers, and indeed the great earth itself.
