abstract: The first Christian missionaries arrived in Japan in the middle of the sixteenth century. They missionized quite a number of Japanese people but also angered many through their disrespectful behavior and destruction of temples and shrines. Less than 100 years later, Japan closed its borders, persecuted Christians, and banned Christianity in total. The reasons for this drastic step weren't solely political but also theological. Theological arguments concerning theism, eschatology, ethics, and theology of religion are found in official edicts, in (...) "disputes" between Christian missionaries and Buddhist scholars, as well as in theological treatise. One of the reoccurring arguments against Christianity includes the description of the arrogant behavior of the missionaries. According to the documents, they displayed an attitude of knowing everything concerning the world next to the ignorant Buddhists. This exclusivist mindset wasn't compatible with the order of Japan and the three teachings. In the eyes of the authorities, this doctrine secured peace and ensured domestic stability. Especially the Japanese and former Christian Fabian Fucan, as well as the Buddhist monk Suzuki Shōsan, adduce various Buddhist, Confucian, and Daoist teachings against the charge of ignorance. Conversely, Fucan's writing, as well as the edicts, records of religious "disputes," and other treatises, include the accusation that Christianity does not contain any new doctrine advancing the local one. Moreover, it is stated that Christian salvation exclusivism suggests a powerless God, and the missionaries were described as hypocrites and liars, as they did not keep their commandments. (shrink)

In french and english speaking countries, the articulation between epistemological beliefs, conceptions of teaching and learning and pedagogical practices of secondary school teachers in the natural sciences and humanities has been little studied (Araújo-Oliveira, 2012 ; Bartos et Lederman, 2014 ; Wanlin et al., 2019). Yet, while teachers display predominantly constructivist beliefs about teaching and learning, their teaching practices remain rather passive (OECD, 2019). Like in Therriault et al. (2018-2023), this article explores the characteristics of epistemological beliefs, conceptions of teaching (...) and learning, and teaching practices among a population of 112 secondary school teachers (beginners, intermediate and experienced) in the humanities and natural sciences in French-speaking Belgium. In a second step, we explore the articulations between these three theoretical constructs either from statistical analyses or from a more interpretative perspective. Quantitative analysis of the data (PCA, factorial ANOVA, correlations and Chi-square) show that teachers’ epistemological beliefs are rather refined, that there is an effect of professional seniority on these beliefs and that there is a link between refined epistemological beliefs and traditional conceptions of teaching and learning. Finally, teachers’ self-reported practices appear to be insensitive to the discipline being taught. (shrink)

Is self-consciousness intentional? Consciousness of oneself-as-object is, in the sense that the subject is there taken as its own object of intentional consciousness. Contrastively, it has been argued that consciousness of oneself-as-subject is not intentional, precisely in that it does not involve taking oneself as an intentional object. Here, it is rather proposed that consciousness of oneself-as-subject is tied to intentionality in that it involves being conscious of oneself as an intentional subject, i.e. as a subject directed at intentional objects (...) transcending oneself-as-subject. This form of self-consciousness is neither reflective, in the sense that it does not involve to take oneself as an object of reflection, nor reflexive, in the sense that it does not involve to be related to oneself but to what-one-is-not, i.e. to the transcending intentional object. It is further argued that consciousness of oneself-as-subject involves two dynamics, as the subject would be indicated to himself by the objects towards which he directs himself. These considerations are here unfolded to consider in particular bodily self-consciousness. (shrink)

In the first part of this paper I characterize a minimal form of self-consciousness, namely pre-reflective self-consciousness. It is a constant structural feature of conscious experience, and corresponds to the consciousness of the self-as-subject that is not taken as an intentional object. In the second part, I argue that contemporary cognitive neuroscience has by and large missed this fundamental form of self-consciousness in its investigation of various forms of self-experience. In the third part, I exemplify how the notion of pre-reflective (...) self-awareness can be of relevance for empirical research. In particular, I propose to interpret processes of sensorimotor integration in light of the phenomenological approach that allows the definition of pre-reflective self-consciousness. (shrink)

Qua hermeneutic-linguistic-pragmatic turn wurde die Freisetzung kommunikativen Handelns kommunikationslogisch, entwicklungstheoretisch und diskursethisch entwickelt und die Form der Verstandigung intersubjektivitatstheoretisch als Moglichkeit sozialer Identitat bestimmt. Mit Peirce kann man das Verstandigungstheorem als Intersubjektivitatsrelation lesen, Intersubjektivitat selbst strukturlogisch "deduzieren". So prazisiert wird die von Habermas vollzogene Umstellung von Subjektivitat auf formale Intersubjektivitat uber Kant, Hegel, Husserl und Mead rekonstruierbar. Dabei kann das begrundungstheoretische Defizit des nur postulierten Formganzen gesellschaftlicher Rationalitat behoben, der formalpragmatisch ausgedunnte Lebensweltbegriff substantiiert und die nicht konsequent ausgefuhrte Methodologie mit (...) der Trias von Metatheorie, empirischer Soziologie und Gesellschaftstheorie scharfer gestellt werden. Die relationenlogische Analyse drangt zur Neulekture des Intersubjektivitatsgedankens. (shrink)

The paper examines the roots of Husserlian phenomenology in Weierstrass's approach to analysis. After elaborating on Weierstrass's programme of arithmetization of analysis, the paper examines Husserl's Philosophy of Arithmetic as an attempt to provide foundations to analysis. The Philosophy of Arithmetic consists of two parts; the first discusses authentic arithmetic and the second symbolic arithmetic. Husserl's novelty is to use Brentanian descriptive analysis to clarify the fundamental concepts of arithmetic in the first part. In the second part, he founds the (...) symbolic extension of the authentically given arithmetic with stepwise symbolic operations. In the process of doing so, Husserl comes close to defining the modern concept of computability. The paper concludes with a brief comparison between Husserl and Frege. While Frege chose to subject arithmetic to logical analysis, Husserl wants to clarify arithmetic as it is given to us. Both engage in a kind of analysis, but while Frege analyses within Begriffsschrift, Husserl analyses our experiences. The difference in their methods of analysis is what ultimately grows into two separate schools in philosophy in the 20th century. (shrink)

There has been much theoretical debate on issues of business ethics during the last decades, but there has been little research which could concretise the content of these issues in terms of practical business. Although business life must frequently deal with concepts such as corporate social performance, business ethics and the acceptability of operations, the content and meaning of these concepts has remained flexible. In addition, rapid internationalisation and globalisation have introduced a number of new phenomena related to corporate social (...) performance. An attempt at defining the concepts more precisely and searching for a potential indicator was considered necessary in order to concretise the business environment facing corporations engaged in internationalisation and globalisation. The connection between corporate social performance and stakeholder theory provides a basis for the proposal put forward here that acceptability of operation could be employed as an indicator of corporate social performance. This approach was then applied to developing a model which could be used to assess corporate social performance. (shrink)

Philosophical considerations as well as several recent studies from neurophysiology, neuropsychology, and psychophysics converged in showing that the peripersonal space is structured in a body-centred manner and represented through integrated sensory inputs. Multisensory representations may deserve the function of coding peripersonal space for avoiding or interacting with objects. Neuropsychological evidence is reviewed for dynamic interactions between space representations and action execution, as revealed by the behavioural effects that the use of a tool, as a physical extension of the reachable space, (...) produces on visual–tactile extinction. In particular, tool-use transiently modifies action space representation in a functionally effective way. The possibility is discussed that the investigation of multisensory space representations for action provides an empirical way to consider in its specificity pre-reflexive self-consciousness by considering the intertwining of self-relatedness and object-directness of spatial experience shaped by multisensory and sensorimotor integrations.

This study was conducted with the aim of outlining a comprehensive picture of the coverage of various sustainability schemes or criteria sets related to the entire value-added chain of biomass and bioenergy and comparing them accordingly. Eight sustainability schemes and one draft directive were chosen for the qualitative comparison: two existing sets of criteria for agricultural biomass (RSPO, RTRS); two existing forest certification schemes (FSC, Finnish FFCS); two newly developed initiatives for biomass for energy raw material (WWF Meta standard, CSB); (...) and three recent proposals for bio energy and biofuels (SSB, Finnish SLF, EU draft directive).The analysis demonstrated that five schemes (RSPO, RTRS, FSC, CSB and SSB) are created for global application and commonly cover all sustainability issues plus the legal framework around it. The WWF Meta standard does also cover all issues, although the economic items are underemphasised. The two Finnish sets (FFCS and SLF) are mainly locally or regionally applied and focus more on environmental issues, as other issues are covered by existing legislation. The EU draft directive focuses mainly on the governance of energy from renewable sources at the European level, emphasising environmental issues. This paper resulted in the proposal of a tri-dimensional approach (sustainability issues; technical biomass conversion routes; physical trade flows) when comparing various biomass and bioenergy schemes and for further development and empirical testing of overall European biomass and bioenergy sustainability.

This paper presents the metaphysics of the Vietnamese Buddhist Zen monk Thich Nhat Hanh. He interprets the Buddhist principle of interdependent arising in terms of interbeing, the idea that everything depends for its existence on everything else. On his view, everything “inter-is” with everything else, or “to be is to inter-be.” His interpretation is particularly interesting in light of the contemporary debate on fundamentality in western metaphysics. By embracing the idea of interbeing, he opposes the view that there are fundamental (...) entities which do not depend for their existence on anything else. I give an outline of Thich Nhat Hanh’s views, answer an objection, and explain his reasons for adopting his standpoint. My aim is not to offer a full defense of his views, but only to show that the often neglected position of metaphysical coherentism, which Thich Nhat Hanh adopts, deserves further consideration.

Why do relationships of friendship and love support partiality, but not relationships of hatred or commitments of racism? Where does partiality end and why? I take the intuitive starting point that important cases of partiality are meaningful. I develop a view whereby meaning is understood in terms of transcending self-limitations in order to connect with things of external value. I then show how this view can be used to distinguish central cases of legitimate partiality from cases of illegitimate partiality and (...) how it puts pressure on the traditional way of thinking about partiality.

Several philosophers have argued that ‘constraints’ constrain (and thereby explain) by virtue of being modally stronger than ordinary laws of nature. In this way, a constraint applies to all possible systems, for a variety of possibility that is broader (that is, more inclusive) than the variety we employ when we say that the ordinary laws of nature apply to all physically possible systems. Explanations by constraint are thus more broadly unifying than ordinary causal explanations. Philosophical examples of good candidates for (...) constraints have heretofore been drawn almost exclusively from fundamental physics. This paper argues for the existence of such constraints (even multiple levels of them) in at least one human science (linguistics), not just in physics. (shrink)

Empirical and experiential investigations allow the distinction between observational and non-observational forms of subjective bodily experiences. From a first-person perspective, the biological body can be (1) an "opaque body" taken as an intentional object of observational consciousness, (2) a "performative body" pre-reflectively experienced as a subject/agent, (3) a "transparent body" pre-reflectively experienced as the bodily mode of givenness of objects in the external world, or (4) an "invisible body" absent from experience. It is proposed that pre-reflective bodily experiences rely on (...) sensori-motor integrative mechanisms that process information on the external world in a self relative way. These processes are identification-free in that the self is not identified as an object of observation. Moreover, it is defended that observational self-consciousness must be grounded on such identification-free processes and pre-reflective forms of bodily experience. (shrink)

A challenge for theories of incomplete descriptions is to capture the consistency of ‘Sobel sequences’ and to account for an asymmetry in the acceptability of utterances of Sobel sequences and ‘reverse Sobel sequences’. David Lewis’s theory of incomplete descriptions answers, unlike many other theories, the challenge from Sobel sequences, but it does not answer the challenge from reverse Sobel sequences. This article presents another asymmetry in the availability of anaphoric readings of Sobel sequences and reverse Sobel sequences, and proposes an (...) explanation of the original asymmetry on its grounds. This provides an answer to the challenge for Lewis’s theory. (shrink)

Dorothee Gelhard ergänzt die Untersuchungen zu Walter Benjamin und dem Phänomen des Darstellbaren in Sprache und Bild. Sie zeigt, dass sich Benjamin mit dem Thema der Erfahrung und der Wahrnehmung im Kontext der Malerei tiefgehend auseinandergesetzt hat. Die Beschäftigung mit Kandinsky, dem Blauen Reiter und Chagall hat bei Benjamin zu einem Nachdenken über Farben und Formen geführt. In den Texten über Phantasie und Wahrnehmung verbindet er seine Beobachtungen der modernen Malerei mit den aus den frühen phänomenologischen Studien gewonnenen Erkenntnissen, (...) sodass sich schliesslich der Begriff des "Denkbildes" und des "dialektischen Bildes" immer klarer herausbildet. Diese frühen Überlegungen Benjamins haben sein Passagen-Werk vorbereitet, in dem er das Nachleben der Vergangenheit in der modernen Grossstadt aufspürt und nach dem Verbleib des Bildbewusstseins des Einzelnen in einer immer technischer werdenden Moderne fragt.

Our view is that fundamental appetitive and defensive motivation systems evolved to mediate a complex array of adaptive behaviors that support the organism’s drive to survive—defending against threat and securing resources. Activation of these motive systems engages processes that facilitate attention allocation, information intake, sympathetic arousal, and, depending on context, will prompt tactical actions that can be directed either toward or away from the strategic goal, whether defensively or appetitively determined. Research from our laboratory that measures autonomic, central, and somatic (...) reactions when processing emotional scenes is described which indicates that motivationally relevant cues, whether appetitive or defensive, capture attention preferentially, prompt enhanced perceptual processing and information gathering, and occasion metabolic arousal that mobilizes the organism for coping actions.

This paper presents a novel methodological approach of how to design, conduct and analyse robot-assisted play. This approach is inspired by nondirective play therapy. The experimenter participates in the experiments, but the child remains the main leader for play. Besides, beyond inspiration from non-directive play therapy, this approach enables the experimenter to regulate the interaction under specific conditions in order to guide the child or ask her questions about reasoning or affect related to the robot. This approach has been tested (...) in a long-term study with six children with autism in a school setting. An autonomous robot with zoomorphic, dog-like appearance was used in the studies. The children’s progress was analyzed according to three dimensions, namely, Play, Reasoning and Affect. Results from the case-study evaluations have shown the capability of the method to meet each child’s needs and abilities. Children who mainly played solitarily progressively experienced basic imitation games with the experimenter. Children who proactively played socially progressively experienced higher levels of play and constructed more reasoning related to the robot. They also expressed some interest in the robot, including, on occasion, affect.

PurposeContinuous patient-reported outcomes to identify and address patients’ needs represent an important addition to current routine care. The aim of this study was to identify and determine important dimensions of health-related quality of life in routine oncological care.MethodsIn a cross-sectional qualitative study, interviews and focus groups were carried out and recorded. The interviewees were asked for their evaluation on HrQoL in general and specifically regarding cancer treatment. The material was transcribed and analyzed using qualitative content analysis based on Mayring. The (...) results were reviewed in an expert discussion.ResultsInterviews with patients and clinicians, as well as five focus groups with clinicians were conducted. Initially, nine deductive and two inductive categories on HrQoL were built. Four categories were excluded following the qualitative content analysis because they were hardly or not at all mentioned by participants. Following on from the analysis of the expert discussion, one dimension was added, and two further categories were excluded. The resulting system consisted of six dimensions: emotional health, physical ailments, autonomy, social functionality, dignity, and resources.ConclusionThe identified dimensions of HrQoL in routine oncological care were found to differ from those used in existing HrQoL measurements for patients. Further research is needed to test and evaluate the presented structure in a larger sample of cancer patients to further assess its psychometric properties. (shrink)

Husserl and Mathematics explains the development of Husserl's phenomenological method in the context of his engagement in modern mathematics and its foundations. Drawing on his correspondence and other written sources, Mirja Hartimo details Husserl's knowledge of a wide range of perspectives on the foundations of mathematics, including those of Hilbert, Brouwer and Weyl, as well as his awareness of the new developments in the subject during the 1930s. Hartimo examines how Husserl's philosophical views responded to these changes, and offers (...) a pluralistic and open-ended picture of Husserl's phenomenology of mathematics. Her study shows Husserl's phenomenology to be a method capable of both shedding light on and internally criticizing scientific practices and concepts. (shrink)

Parallel zur Philosophie der symbolischen Formen publizierte Cassirer in den 20er Jahren mehrere Aufsätze zur Kunst, die klarer noch als in den philosophischen Darstellungen die Rolle der Literatur als Vermittlerin zwischen der Naturerkenntnis und dem Sittlichen thematisieren. Die Autorin untersucht, wie Cassirers Blick auf die Kultur dabei vor allem von Goethes naturwissenschaflichen Schriften geprägt ist. Sie zeigt, wie Cassirer in den Jahren des Exils den Dialog mit Aby Warburg fortsetzte, mit dessen Kulturwissenschaftlicher Bibliothek er bis zu deren Übersiedlung nach London (...) eng zusammengearbeitet hat. Dort entwickelte er in erneuter Lektüre Goethes, Schillers, Corneilles und Thomas Manns eine Kulturwissenschaft, in der Natur- und Geisteswissenschaften einander nicht gegenüberstehen, sondern sich ergänzen"--Back cover.

Williams’s attack on the ‘morality system’ in Ethics and the Limits of Philosophy was preceded by his famous but misunderstood essay ‘Moral Luck’. This essay pursues two principal aims. First and foremost, I take a fresh look at Williams’s argument in ‘Moral Luck’, to assess its defensibility. Second, I investigate how Williams’s treatment of moral luck shapes and informs the wider assault on the ‘morality system’ which reached its fullest expression in the later work. We can learn something about both (...) of Williams’s projects—his defence of moral luck, and his attack on the morality system—by seeing how each of these projects contributes to the other. Drawing on Williams’s discussion of Gauguin’s desertion of his family for a life of artistic endeavour in Tahiti, six interpretations of Williams’s argument are suggested. While some of these are better than others, none is completely satisfying or convincing. It is suggested, in conclusion, that the attack on anti-luckism does not make an indispensable contribution to Williams’s attack on the morality system. (shrink)

The Diamond Sutra is one of the earliest and most treasured of the Perfection of Wisdom Sutras and had a wide influence on the development of Zen Buddhism. There has been, in recent years, great interest in one particular form of sentences that repeatedly occur in the sutra, sentences of the form “A is not A, therefore it is A”. These sentences display what has been called the “logic of not” or the “logic of affirmation-in-negation”. They are of special interest (...) since they do not only encapsulate one of the central insights of Zen Buddhism, that of nonduality, but at the same time seem to go against one of the most orthodox laws of logic in Western philosophy, the law of identity. This paper discusses the interpretation of these “diamond sentences” by the Vietnamese Zen monk Thich Nhat Hanh. I present Thich Nhat Hanh’s interpretation of the diamond sentences in terms of interbeing and go on to argue that and explain how, on his interpretation, the validity of the law of identity is indeed rejected. Finally, I spell out consequences for formulating a “logic of Zen” and for a related debate about the validity of the law of non-contradiction in Zen. (shrink)

ABSTRACT This paper seeks to clarify Husserl’s critical remarks about Kant’s view of logic by comparing their respective views of logic. In his Formal and Transcendental Logic Husserl criticizes Kant for not asking transcendental questions about formal logic, but rather ascribing an ‘extraordinary apriority’ to it. He thinks the reason for Kant’s uncritical attitude to logic lies in Kant’s view of logic as directed toward the subjective, instead of being concerned with a ‘“world” of ideal Objects’. Whereas for Kant, general (...) logic is about laws of reasoning. Husserl thinks that formal logic should describe formal structures. Husserl claims that if Kant had had a more comprehensive concept of logic, he would have thought of raising critical questions about how logic is possible. This kind of criticism cannot itself use forms of judgments or syllogisms of logic, nor even the ‘inferential’ [schliessende] method more generally, but should be descriptive in nature. Husserl's transcendental phenomenology is the method for such criticism. The paper argues that this results in reflection, and possibly revision, of the logical principles with respect to the normative goals governing the investigation in question. (shrink)

We examine corporate governance diversity within a Coasian framework of stakeholder rights, where the central role of governance is to ensure that necessary firm-specific investments are made. This Coasian perspective on stakeholder theory offers a unifying framework towards a global theory of comparative corporate governance, bridging the gap between economic theories of the firm and stakeholder theory, also offering an economics-based alternative to agency theory that explicitly accounts for stakeholder rights. The Coasian perspective encompasses a diversity of corporate governance systems, (...) but does not imply a unique global corporate governance benchmark. We posit that governance is firm dependent and endogenous conditional on the constraints imposed by a national governance system; consequently, there should be no systematic relationship between governance and firm performance once the national constraints are controlled for. However, the same national corporate governance system constraints confer comparative advantages to firms whose efficient levels of firm-specific investments are favored. (shrink)

Linguistic category learning has been shown to be highly sensitive to linear order, and depending on the task, differentially sensitive to the information provided by preceding category markers (premarkers, e.g., gendered articles) or succeeding category markers (postmarkers, e.g., gendered suffixes). Given that numerous systems for marking grammatical categories exist in natural languages, it follows that a better understanding of these findings can shed light on the factors underlying this diversity. In two discriminative learning simulations and an artificial language learning experiment, (...) we identify two factors that modulate linear order effects in linguistic category learning: category structure and the level of abstraction in a category hierarchy. Regarding category structure, we find that postmarking brings an advantage for learning category diagnostic stimulus dimensions, an effect not present when categories are non‐confusable. Regarding levels of abstraction, we find that premarking of super‐ordinate categories (e.g., noun class) facilitates learning of subordinate categories (e.g., nouns). We present detailed simulations using a plausible candidate mechanism for the observed effects, along with a comprehensive analysis of linear order effects within an expectation‐based account of learning. Our findings indicate that linguistic category learning is differentially guided by pre‐ and postmarking, and that the influence of each is modulated by the specific characteristics of a given category system.

The paper discusses Husserl’s notion of definiteness as presented in his Göttingen Mathematical Society Double Lecture of 1901 as a defense of two, in many cases incompatible, ideals, namely full characterizability of the domain, i.e., categoricity, and its syntactic completeness. These two ideals are manifest already in Husserl’s discussion of pure logic in the Prolegomena: The full characterizability is related to Husserl’s attempt to capture the interconnection of things, whereas syntactic completeness relates to the interconnection of truths. In the Prolegomena (...) Husserl argues that an ideally complete theory gives an independent norm for objectivity for logic and experiential sciences, hence the notion is central to his argument against psychologism. In the Double Lecture the former is captured by non-extendibility, that is, categoricity of the domain, from which, so Husserl assumes, syntactic completeness is thought to follow. In the so-called ‘mathematical manifolds’ the expressions of the theory are equations that are reducible to equations between elements of the theory. With such an equational reduction structure individual elements of the domain are given criteria of identity and hence they are fully determined. (shrink)
