The aim of this paper is to examine the relationship between education and technological rationality from the perspective of the philosophy of education, and to show that while education is deeply related to technique, skills, or technology, it can never be reduced to technical knowledge, and that there are things in education that overflow technical knowledge. I will here ask why there is something in education that overflows technical knowledge — I will define it as knowledge of pathos — and (...) why it is necessary to redefine the meaning of education in terms of knowledge of pathos. In order to address this issue, I will first examine the relationship between technology and transcendence in the world of education in Kei Hachiya’s Education and Transcendence. Second, I will show that recent outstanding theoretical achievements of Japanese philosophers of education — Satoji Yano’s Education from the Perspectives of Gift and Exchange, Yasuo Imai’s Medial Perspective on Education, and Tsunemi Tanaka’s Clinical Theory of Human Becoming — are all located within the problematic area of ‘technology-pathos-education’. Finally, I would like to propose a ‘philosophy of education built on fragile parts’, with a view to redefining education through the knowledge of pathos, paying attention to the experience of pathei mathos and the opportunity of weakness in the philosophy of education.

This is a brief historical view, based on my personal experience, of the phenomenological study of the assembly of actin in Japan. The morphogenesis and dynamics of protein filaments and cytoskeleton now represent one of the central problems in cell biology. The approach to this problem at the molecular level was first undertaken on actin from muscle.

What chemists take as molecular structure is a theoretical construct based on the concepts of chemical bond, atoms in molecules, etc. and hence it should be distinguished from tangible structures around us. The practical adequacy of it has been demonstrated by the established method of retro-synthetic analysis, for instance. But it is not derived a priori from quantum mechanical treatments of the molecule and criticized for being irrelevant to the reality of the molecule. There is persistent skepticism about it. The (...) present study aims to overcome this skepticism by having recourse to the concepts of affordance and phenomenal field. The basic idea of our approach is suggested by the following statement of Niels Bohr: ‘evidence obtained under different experimental conditions cannot be comprehended within a single picture but must be regarded as complementary in the sense that only the totality of the phenomena exhausts the possible information about the objects’. This implies that we should take account of a context in which the cognition of a fact arises when we think about human activities including science. This can be realized by invoking affordances of a complex such as {agent, devices, methods, substances, surroundings}. That is to say, affordances are context-relative dispositional attributes of {agent-material world} complexes as is asserted by Harré and Llored. The phenomenal field is a conceptual device which schematizes the contextual aspect of affordance and, more importantly, serves as a link between the concept of affordance and Kant’s theory of knowledge, by which alone affordances are realized as the dispositional properties of {agent-material world} complexes. Because affordances become actualized in various phenomenal fields, affordances of one and the same object may well be distinct from one another. In conclusion we can take that molecular structure is the affordance of a complex that includes a chemist who is engaged in organic synthesis, whereas a quantum mechanical picture of the molecule may be one of the possible affordances of a complex that includes a quantum chemist who cares about electronic states of the molecule.

The classical model of the molecule assumes that it has a definite shape and structure like a mechanical object in the world of possible experience. This study deals with this assumption so as to shed some light on the foundations of the model. Arguments based on Kant’s theory of transcendental idealism suggest that neither shape nor structure are attributes of the molecule, but are rather contributions of the subject. This claim has great relevance to the questions of whether or not (...) a quantum treatment of the molecule can derive structure without recourse to any approximation, and the possible existence of emergence and downward causation. The answer to the first question is in the negative, and to the second is that agnosticism is the only possible attitude to have toward this problem. We are creatures who can only imagine what is going on by observing phenomena. All that is accessible to us is the modal structure of the model. The causal structure of the real system is not. From the same point of view and taking the concept of the affordance into account, the adequacy of the concept of molecular structure will be argued. The point is to specify what objects the concept can legitimately be applied to. Also briefly discussed in relation to shape and structure is the idea that molecular chirality might be a probe to reveal the nature of space. (shrink)

Since molecules are inaccessible to immediate observation, our conception of the molecule is brought about by transdiction which entails invention of various transcendental ideas. In organic chemistry we think that molecules consist of atoms, bonds, functional groups, etc. This is, however, not the unique description of the molecule as is shown by quantum mechanical calculations, for example. Then, what description represents the real molecule? Before asking this question, we have to consider what the real molecule is in the first place. (...) Constructive realism distinguishes our cognitive world and the world just given, and claims that we should accept the former as reality. Understanding our cognitive world is possible only through construction of micro-worlds. Atoms, bonds, functional groups, etc., are micro-worlds which make sense in a theoretical framework of organic chemistry. In this study we translate a micro-world to an affordance and paraphrase it as a context-relative dispositional attribute of an {agent-world} complex. Then, we can understand that it is what we take as molecular structure, not what might be out there to be found, that we should accept as reality. Excluding metaphysical fictions from scientific arguments, constructive realism makes science a meaningful activity. Constructive realism claims that, for getting knowledge of the world, we have to integrate information into our own linguistic frame, i.e., to translate it. Strangification is a technique of intentionally taking an accepted proposition out of one scientific system and putting it into a completely different context. As is the case with translation, strangification brings about deeper understanding of philosophical as well as scientific grounds on which the proposition system holds. We apply this method to molecular structure and reveal that it is an ingenious model to describe molecular behavior in multi-molecular systems with strong interactions between molecules. Information provided by strangification is essential to claim the legitimacy of a proposition system. As far as strangification is properly applied, relativism is irrelevant to constructive realism.

In modern German ‘Anschauung’ is translated as intuition. But in Kant’s technical philosophical context, it means an intuition derived from previous visualizations of physical processes in the world of perceptions. The nineteenth century chemists’ predilection for Kantian Anschauung led them to develop an intuitive representation of what exists beyond the bounds of the senses. Molecular structure is one of the illuminating outcomes. (Ochiai 2021, pp. 1–51) This mental habit seems to be dominant among chemists even in the twentieth century, (...) as is illustrated by the electronic theory of organic chemistry and the frontier orbital theory as well. The former assumes that (1) bonds are paired electrons shared by bonded atoms—in fact, electrons in molecules are not localized in bonds; (2) the difference of electronegativities between bonded atoms causes electron drifts—expressed by the curly arrow—that result in bond formation or bond cleavage. The latter focuses on the orbitals that make the greatest contribution to the energy of a system undergoing electron delocalization, while the LCAO method says, as is suggested by the word Linear Combination of Atomic Orbitals, molecular orbitals should be constructed from all of the atomic orbitals that have the appropriate symmetry. In other words, every molecular orbital contributes to some extent to the electronic state of a molecule. The curly arrow in the electronic theory and the orbital lobe in the frontier orbital theory illustrate an intuitive character of these theories. Although both theories rely on such simple and qualitative models rather than mathematically rigid quantum mechanical calculations, they are successful in explaining, predicting, and designing chemical reactions. What makes these prima facie intuitive theories so successful? In this study we address this problem from a historical and philosophical as well as scientific point of view. The key to solve this problem is that they are concerned with only bond formation or bond cleavage, in which the localized-bond principle holds. (shrink)

Abstract‘Structure’ is the term whose proper use is exemplified by an expression like ‘the structure of a diesel-engine,’ in which what is referred to is accessible to immediate observation. It is also used figuratively like ‘social structure.’ While unobservable, what is referred to is empirically accessible. By contrast, molecules are neither observable nor empirically accessible. What philosophical grounds enable us to design invisible structure of molecules? Our cognition of objects becomes realized as phenomena when objects are given to our phenomenal (...) fields. (Ochiai, Found Chem 22:77–86, 2020a, Found Chem 22:457–465, 2020b, A philosophical essay on molecular structure, Cambridge Scholars Publishing, Newcastle upon Tyne, pp 147–174, 2021) A phenomenal field is a pictorial representation of the mind’s self-transcending character and shows the relation between ‘self’ and ‘world.’ Molecular structure becomes realized as an affordance of molecules in a phenomenal field proper to organic chemists. It is a context-sensitive dispositional attribute of an {organic chemist-world} complex. Although designing molecules presupposes molecular structure, the latter is not sufficient for the former to make sense. Molecules must be designable as well. Designing molecules aims to create or modify molecular structure in order to provide compounds with certain chemical and/or physical properties. That is, designable molecules make sense in contexts in which they serve as a means to achieve this purpose and become realized as an affordance. Given that molecular structure and designable molecules are affordances of molecules, the fact that there are contexts in which they make sense provides grounds for conceiving and designing invisible structure of molecules. Heidegger’s arguments in Being and Time about characteristics of the being of beings corroborate our argument that what becomes realized as an affordance exists as what he calls a useful thing for us.

Fanconi anaemia (FA) comprises a group of autosomal recessive disorders resulting from mutations in one of eight genes (FANCA, FANCB, FANCC, FANCD1, FANCD2, FANCE, FANCF and FANCG). Although caused by relatively simple mutations, the disease shows a complex phenotype, with a variety of features including developmental abnormalities and ultimately severe anaemia and/or leukemia leading to death in the mid teens. Since 1992 all but two of the genes have been identified, and molecular analysis of their products has revealed a complex (...) mode of action. Many of the proteins form a nuclear multisubunit complex that appears to be involved in the repair of double‐strand DNA breaks. Additionally, at least one of the proteins, FANCC, influences apoptotic pathways in response to oxidative damage. Further analysis of the FANC proteins will provide vital information on normal cell responses to damage and allow therapeutic strategies to be developed that will hopefully supplant bone marrow transplantation.

One of the profound changes in cellular morphology during mitosis is a massive alteration in the organization of microfilament cytoskeleton. It has been recently discovered that nonmuscle caldesmon, an actin and calmodulin binding microfilament‐associated protein of relative molecular mass Mr = 83000, is dissociated from microfilaments during mitosis, apparently as a consequence of mitosis‐specific phosphorylation. cdc2 kinase, which is a catalytic subunit of MPF (maturation or mitosis promoting factor), is found to be responsible for the mitosis‐specific phosphorylation of caldesmon. Because (...) caldesmon is implicated in the regulation of actin myosin interactions and/or microfilament organization, these results suggest that cdc2 kinase directly affects microfilament re‐organization during mitosis.

How can we effectively promote the public’s prevention of coronavirus disease 2019 infection? Jordan et al. found with United States samples that emphasizing either self-interest or collective-interest of prevention behaviors could promote the public’s prevention intention. Moreover, prosocially framed messaging was more effective in motivating prevention intention than self-interested messaging. A dual consideration of both cultural psychology and the literature on personalized matching suggests the findings of Jordan et al. are counterintuitive, because persuasion is most effective when the frame of (...) the message delivered and the recipient of the message are culturally congruent. In order to better understand the potential influence of culture, the current research aimed to replicate and extend Jordan et al. findings in the Japanese context. Specifically, we examined the question whether the relative effectiveness of the prosocial appeal is culturally universal and robust, which types of ‘others’ especially promote prevention intention, and which psychological mechanisms can explain the impact of messaging on prevention intention. In Study 1, we confirmed that self-interested framed, prosocially framed, and the combination of both types of messaging were equally effective in motivating prevention intention. In Study 2, we found that family-framed messaging also had a promoting effect similar to that from self-interested and prosocial appeals. However, the relative advantage of prosocial appeals was not observed. Further, a psychological propensity relevant to sensitivity to social rejection did not moderate the impact of messaging on prevention intention in both studies. These results suggest that since engaging in the infection control itself was regarded as critical by citizens after public awareness of COVID-19 prevention has been sufficiently heightened, for whom we should act might not have mattered. Further, concerns for social rejection might have had less impact on the prevention intentions under these circumstances. These results suggest that the relative advantage of a prosocial appeal might not be either culturally universal or prominent in a collectivistic culture. Instead, they suggest that the advantages of such an appeal depends on the more dynamic influence of COVID-19 infection. (shrink)

The COVID-19 pandemic has significantly affected the exhibition of artworks in museums and galleries. Many have displayed their collection online. In this context, experiencing an online exhibition is essential for visitors to appreciate and understand the artwork. Compared with offline exhibitions, visitors to online exhibitions are often unable to communicate their experiences with other visitors. Therefore, in this study, by facilitating communication via Zoom call, we established a system that allows two people to visit the museum together through the Google (...) Arts and Culture website. To reduce the psychological distance between online visitors and help increase user engagement, we designed and developed a media device based on moiré pattern visualization of electroencephalography signals. The participants were divided into two groups to visit the online museum, communicating remotely through Zoom. The objective of this study was to test whether a real-time EEG signal visualization device could help close the psychological distance between participants and whether it could increase user engagement with the online exhibition. Participants were randomly assigned to either the normal online exhibition experience group or EEG signal visualization device group. Participants in the NOEE group experienced four online exhibitions together. The conditions for participants in the ESVD group remained the same, apart from adding a media device to enable them to visualize EEG signals. A total of 40 university students participated in this study. Independent samples t-tests revealed that participants in the ESVD group perceived a significantly closer psychological distance between themselves and the participants on the opposite side than those in the NOEE group. A one-way ANOVA revealed that participants experienced Task3 with significantly closer psychological distance assessments than Task1, Task2, and Task4. Repeated ANOVAs revealed that participants in the ESVD group had higher overall user engagement than those in the NOEE group, with marginal significance. Thus, this study shows that EEG visualization media devices can reduce the psychological distance between two participants when experiencing an online exhibition. Moreover, it can increase user engagement to some extent. (shrink)
