The propositional fragment L 1 of Leniewski's ontology is the smallest class (of formulas) containing besides all the instances of tautology the formulas of the forms: (a, b) (a, a), (a, b) (b,). (a, c) and (a, b) (b, c). (b, a) being closed under detachment. The purpose of this paper is to furnish another more constructive proof than that given earlier by one of us for: Theorem A is provable in L 1 iff TA is a thesis of first-order (...) predicate logic with equality, where T is a translation of the formulas of L 1 into those of first-order predicate logic with equality such that T(a, b) = FblxFax (Russeltian-type definite description), TA B = TA TB, T A = TA, etc. (shrink)

Cet article examine le rapport entre l’Idée platonicienne du Bien et l’au-delà de l’essence de Levinas.

The purpose of this paper is to clarify Prajñākaragupta’s view of mental perception ( mānasapratyakṣa ), with special emphasis on the relationship between mental perception and self-awareness. Dignāga, in his PS 1.6ab, says: “mental [perception] ( mānasa ) is [of two kinds:] a cognition of an [external] object and awareness of one’s own mental states such as passion.” According to his commentator Jinendrabuddhi, a cognition of an external object and awareness of an internal object such as passion are here equally (...) called ‘mental perception’ in that neither depends on any of the five external sense organs. Dharmakīrti, on the other hand, considers mental perception to be a cognition which arises after sensory perception, and does not call self-awareness ‘mental perception’. According to Prajñākaragupta, mental perception is the cognition which determines an object as ‘this’ ( idam iti jñānam ). Unlike Dharmakīrti, he holds that the mental perception follows not only after the sensory perception of an external object, but also after the awareness of an internal object. The self-awareness which Dignāga calls ‘mental perception’ is for Prajñākaragupta the cognition which determines as ‘this’ an internal object, or an object which consists in a cognition; it is to be differentiated from the cognition which cognizes cognition itself, that is, self-awareness in its original sense.

In this article Kobayashi Toshiaki discusses the importance in all periods of Karatani’s oeuvre of the notion of an “exterior” that necessarily falls beyond the bounds of a system, together with the notion of “singularity” as that which cannot be contained within a “universal.” The existential dread vis-à-vis the uncanny other that Karatani in his early works of literary criticism had initially found to be the underlying tone in Sōseki’s works remained with Karatani himself throughout his career and is (...) what had drawn him closer to philosophy. This sense of the “exterior” to—or other than—the normality of consciousness and the meaningfulness of the world is then extended and applied as the “exterior to systems” in his analyses of logical, mathematical, and linguistic systems, in his reading of Marx’s discussion of capitalist economics, and most recently in his analysis of commodity exchange between communities.

The inositol phosphate metabolism network has been found to be much more complex than previously thought, as more and more inositol phosphates and their metabolizing enzymes have been discovered. Some of the inositol phosphates have been shown to have biological activities, but little is known about their signal transduction mechanisms except for that of inositol 1,4,5‐trisphosphate. The recent discovery, however, of a number of binding proteins for inositol high polyphosphate [inositol 1,3,4,5‐tetrakisphosphate (IP4), inositol 1,3,4,5,6‐pentakisphosphate, or inositol hexakisphosphate] enables us to (...) speculate on the physiological function of these compounds. In this article we focus on two major issues: (1) the roles of inositol high polyphosphates in vesicular trafficking, especially exocytosis, and (2) pleckstrin homology domaincontaining IP4 binding proteins involved in the Ras signaling pathway.

These essays are concerned with developing a dialogue between humanism and historical materialism in human geography, and to demonstrate the creative tension which emerges through the mediation of their different frames of reference.

It has been suggested that preparing to teach and teaching are conditionally effective in enhancing one’s own learning. This paper focuses on interactivity—the level of teacher-student interaction in expected or actual teaching—as the potential key to understanding and controlling the variability in the effectiveness of learning by preparing to teach and teaching. By summarizing and reanalyzing the results of previous studies, I suggest that the learning benefits of studying with the expectation of direct teaching (i.e., teaching a student face-to-face) are (...) greater than those of studying with the expectation of indirect teaching (i.e., teaching a student indirectly by creating a lecture video, providing written explanations, or using other means) and that learning by direct teaching surpasses learning by explaining to oneself or indirect teaching at least after preparing to do so. Next, three candidate explanations for the impact of interactivity are discussed: the advantages of asking and answering questions, obtaining additional information about and from one’s student, and enhancing one’s motivation to process learning material deeply while preparing to teach and teaching. Finally, I conclude with the remaining questions and directions for future research. (shrink)

The Fist-Edge-Palm task, a manual hand task, has been used to detect frontal dysfunctions in clinical situations: its performance failures are observed in various prefrontal cortex -related disorders, including schizophrenia. However, previous imaging studies reported that the performance of the FEP task activated motor-related areas, but not the PFC. Here, we aimed to investigate the relationships between the performance of the FEP task and PFC functions. Hemodynamic activity in the PFC, including the dorsolateral PFC and frontal pole, was recorded. Healthy (...) young subjects performed the FEP task as well as a palm tapping task three times. The subjects also completed a Wisconsin Card Sorting Test and Schizotypal Personality Scale questionnaire. We found that hemodynamic activity in the PFC increased in the first trial of the FEP task but decreased considerably in the second and third trials compared to the PT task. The number of performance errors in the FEP task also decreased in the second and third trials. Error reduction in the FEP task between the first and second trials was negatively correlated with schizotypal trait and the number of perseveration errors in the WCST. Furthermore, changes in the PFC hemodynamic activity between the first and second trials were positively correlated with error reduction in the FEP task between the first and second trials, and negatively correlated with the number of perseveration errors in the WCST. These results suggest that learning in the FEP task requires PFC activation, which is negatively associated with perseveration errors in the WCST. The results further suggest that the FEP task, in conjunction with near-infrared spectroscopy, may be useful as a diagnostic method for various disorders with PFC dysfunction. (shrink)

In meinem Aufsatz möchte ich die Ästhetik auf ihre Möglichkeit hin überprüfen, eine grundlegende Theorie des „Sinnlichen" innerhalb der menschlichen kulturellen Tätigkeiten zu sein. Dieses Vorhaben werde ich damit beginnen, Heideggers Kritik an der traditionellen Ästhetik zu behandeln. Dem überlieferten Ästhetikverständnis liegt nach Heidegger offenbar diesselbe vorstellend-vergegenständlichende Denkweise zugrunde, die der ganzen abendländischen Geschichte eigen ist. Doch lässt sich nach Heidegger mittels der auf dem metaphysischen Denken basierenden Ästhetik das Wesen der Kunst niemals erschöpfend behandeln, da die Kunst als das (...) Ins-Werk- Setzen der Wahrheit verstanden werden muss.Freilich nimmt Heidegger immer eine kritische Haltung gegenüber der sogenannte „Ästhetik" ein, aber man kann dadurch auch die Möglichkeit einer anderen erweiterten Ästhetik finden, die die anfängliche Wahrheitsfunktion der aisthesis als Wahr-nehmung ins Auge zu fassen versucht. Von diesem grundlegenden Standpunkt aus möchte ich mich mit einem gegenwärtigen Versuch des ästhetischen Denkens (Wolfgang Welsch) und mit einer nicht-europäischen traditionellen Ästhetik (Shüzö Kuki) beschäftigen.

Este ensayo está dedicado a la serie grey paintings del artista norteamericano Cy Twombly. A partir de un análisis de Panorama y Cold Stream, planteo que la serie se vincula a formas de inscripción asociadas, simultáneamente, a lo verbal y lo pictórico. Si bien no es posible identificar letras ni palabras, estas obras manifiestan un estrecho vínculo con una dimensión gestual y corporal de la escritura. En mi análisis establezco relaciones con inscripciones arcaicas, con la criptografía, y con procesos de (...) alfabetización escolar. (shrink)

Continuing Pfeiffer 1972, Pfeiffer 2018 examines inherited Dravidian etyma of Kurux, one of the most northerly Dravidian languages. After an overview of the book, we discuss problems involved in Pfeiffer’s arguments, methods, and materials. Then we try to narrow down the conditions of some of the sound changes Pfeiffer proposes, in conformity with the Neogrammarian hypothesis of regularity. We also point out that closer study of word-final phonology would answer some of the pending questions of Kurux-Malto morphology. Finally, we argue (...) that phonological and morphological reconstruction can unveil more features to help revise the subgrouping of Kurux-Malto in the Dravidian family. (shrink)

西田幾多郎(一八七〇‐一九四五)の人生。それは一人の人間の個別的な営みを超え、明治から昭和に至る奔流のただなかに姿を見せ始めた「日本」を集約し、体現するものだった。同時代の多彩な資料に基づく実証的手法 によって克明に描き出される哲学者の苦悩と格闘の人生に、近代日本の成立過程に現出した幾多の問題系を照射する斬新な評伝的批評。.

Social or relational egalitarians try to defend democracy non-instrumentally as a constitutive element of a society where no one stands as inferior or superior to anyone else. However, they face an instrumentalist challenge from within: Why not uphold a non-democratic regime if it outperforms democracy in protecting or promoting egalitarian social relations, for example, by stably producing substantive political decisions that guard against social hierarchies? This article explores the best response to this challenge from the social egalitarian non-instrumentalist standpoint. It (...) argues that the instrumentalist challenge can be accommodated without abandoning the essential non-instrumentalist commitment to democracy; while a nondemocratic regime may be justified under less-than-ideal circumstances as a contingently effective means to realize more social equality, democracy can nevertheless be viewed as a necessary condition for the realization of full social equality.

「主体」はもちろんsubjectの翻訳語である。明治以降、この語がわが国に入ってくると、「主観」「主体」「主語」などさまざまな翻訳語があらわれる。たとえば西田幾多郎は、初期は「主観」をつかっているが、 後期になると「主体」しか出てこなくなる。この移行ははたして何を意味するのだろうか。戦後には、「主体性論争」がわき起こり、たとえば学生運動では「主体性」という言葉がキーワードとなった。明治期の受容から、 戦後、そして現代に至るまで、それぞれの時代の趨勢となった思想に伏流する「主体」を追い続け、日本近代思想史にあらたな視座を提供する、知的興奮にあふれた一冊。.
