Originally published as 「明治の哲学界：有機体の哲学とその系譜」in 井上克人編『豊饒なる明治』, Kansai Daigaku Shuppannbu, 2012, 3–22. Translated by Morisato Takeshi. German Idealism was introduced to Japanese intellectuals in the middle of Meiji era and was mainly received from a mystical or religious perspective, as we see in Inoue Tetsujirō’s “harmonious existence,” Inoue Enryō’s “unity of mind and body,” and Kiyozawa Manshi’s “existentialism.” Since these theories envisioned true reality as a unified and living whole, I group them under the label “philosophy of organism” and from there (...) argue that their conviction that “all is truth and truth is all” was shaped in large part by the Awakening of Faith in the Mahayana. The understanding of Buddhist concepts by Meiji philosophers was philosophical in its content, and those who devoted themselves to the study of Western philosophy were encouraged to describe Eastern thought in Western philosophical terms. As a result, the philosophical world of the Meiji era developed an original standpoint that unified Eastern and Western perspectives by means of a logic of “phenomena-in-reality.”. (shrink)

According to the “truthmaker maximalism”, every true contingent proposition is made true by something in the world, called its truthmaker. Although at first sight the maximalism seems to be a natural position, it has serious difficulties, especially concerning negative truths. In view of this, many truthmaker theorists adopt some non-maximalist position. It is not clear, however, whether these non-maximalists are justified, since existing reasons to justify the non-maximalism are not good enough. In this paper, then, I shall propose a new (...) reason for the non-maximalism, which consists in the observation that the maximalism cannot acknowledge the widely accepted view that certain inferences involving logical constants are valid in the properly logical sense.

Pioneer transcription factors, by virtue of their ability to target nucleosomal DNA in silent chromatin, play crucial roles in eliciting cell fate decisions during development and cellular reprogramming. In addition to their well‐established role in chromatin opening to activate gene expression programs, recent studies have demonstrated that pioneer factors have the complementary function of being able to silence the starting cell identity through targeted chromatin repression. Given recent discoveries regarding the repressive aspect of pioneer function, we discuss the basis by (...) which pioneer factors can suppress alternative lineage programs in the context of cell fate control.

I tested the hypothesis that, in infant-mother-sibling interactions, infants with older siblings aged 11 to 24 months produce deictic gestures when they are proximal to, or engaging in joint attention with, their mothers more frequently than same-aged infants without siblings. Fifteen infant-mother dyads and 10 infant-mother-sibling triads were individually observed for 15 minutes in a playroom full of toys. Infants involved in infant-mother-sibling interactions produced more deictic gestures when they were proximal to their mothers than infants in infant-mother interactions. Further, (...) infants involved in infant-mother-sibling interactions accompanied their gestures with vocalizations at a higher rate than infants in infant-mother interactions. This result suggests that infants with older siblings monitor their mothers more carefully in interactions in which their sibling is also present, and that they produce deictic gestures in order to effectively elicit joint action with their mothers.

One most common problem in reinforcement learning systems (e.g. Q-learning) is to reduce the number of trials to converge to an optimal policy. As one of the solution to the problem, k-certainty exploration method was proposed. Miyazaki reported that this method could determine an optimal policy faster than Q-learning in Markov decision processes (MDPs). This method is very efficient learning method. But, we propose an improvement plan that makes this method more efficient. In k-certainty exploration method, in case there is (...) no k-uncertainty rule (rules which aren’t selected more than k times) in current state, an agent sometimes walks randomly until it finds a state where it can select a k-uncertainty rule. We think that this behavior is not efficient. To reduce this useless behavior, we propose combining k-certainty exploration method with Dynamic programming (DP). Miyazaki’s system uses DP after all rules are executed at least k times. But, our method uses k-certainty exploration method along with DP during learning. Our method, takes two pattern actions. In case an agent can select k-uncertainty rules, one of these rules is selected at random as k-certainty exploration method. In another case there is no k-uncertainty rule, behavior of agent is different from the behavior of k-certainty exploration method. In that case, our method uses DP to compute an optimal policy for moving from a current state to a state in which some k-uncertainty rules remain. The model for DP is constructed by using only known states. The outline will be described below. First, an agent makes a map constructed by using only known states. In the map, goals are states in which there are k-uncertainty rules and arbitrary state values are set in these states. Point to which attention should be paid is that the map is not given from outside. It is made from only experience. Next, each state values of states in which there are only k-certainty rules in the map are computed by DP (we used Policy Iteration). Finally, an agent continues to select greedy action until it arrives at a state in which it can select a k-uncertainty rule. By this improvement, we expect it can determine an optimal policy faster than k-certainty exploration method. And we have verified that our exploration method can determine an optimal policy faster than k-certainty exploration method by computer simulation. (shrink)

Productive sets are sets which are “effectively non recursively enumerable”. In the same spirit, we introduce a notion of “effectively nonrecursive sets” and prove an effective version of Post's theorem. We also show that a set is recursively enumerable and effectively nonrecursive in our sense if and only if it is effectively nonrecursive in the sense of Odifreddi [1].

This study compares Pairs of subjects with Single subjects in a task of discovering scientific laws with the aid of experiments. Subjects solved a molecular genetics task in a computer micro‐world (Dunbar, 1993). Pairs were more successful in discovery than Singles and participated more actively in explanatory activities (i.e., entertaining hypotheses and considering alternative ideas and justifications). Explanatory activities were effective for discovery only when the subjects also conducted crucial experiments. Explanatory activities were facilitated when paired subjects made requests of (...) each other for explanation and focused on them. The study extends from individual to collaborative discovery activities the importance to the discovery process of setting goals to find hypotheses and evidence (Dunbar, 1993) and to construct explanations of phenomena and processes encountered in examples (Chi, Bassok, Lewis, & Glaser, 1989).

The purpose of this study is to investigate the relationship between a firm’s strategy and consumers’ decisions in the presence of the paradox of choice and sharing personal information. The paradox of choice implies that having too many choices does not necessarily ensure happiness and sometimes having less is more. A new model is constructed introducing a factor of information sharing into the model of a previous study that embedded the paradox of choice only (Kinjo and Ebina in AI Soc (...) 30(2):291–297, 2015). A key feature of the model is its disutility function. It is demonstrated that if the sign of the cross derivative of the function is positive (negative) at the optimum, there is a positive (negative) correlation between the degree of sharing personal information chosen by the consumers and the number of products offered by the firm in its recommendation systems. It is also numerically indicated that the profit function of the firm becomes convex or concave depending on the shape of the disutility function. These results suggest that firms should carefully investigate the shape of the disutility function, under the paradox of choice and sharing personal information. (shrink)

The purpose of our study is to investigate the effects of the number of products, product attributes, and prices on consumer confusion, conduct a numerical analysis to check the robustness of the results, and present an example of the cell phone market in Japan. Following an ideal point model and embedding the number of products and product attributes, we clarify how these factors affect consumer confusion and purchase probability. We show that as the number of product attributes increases, the choice (...) probability of each product becomes equal, implying that consumer confusion occurs. This result is robust to the introduction of prices as strategic variables. (shrink)

This paper aims to improve on Michael Lynch’s functionalist account of truth-grounding. According to Lynch, truth is grounded in another (non-generic) alethic property when the latter has all the conceptually essential features of truth. However, this view faces a problem raised by Marian David (“Lynch’s Functionalist Theory of Truth”) and Crispin Wright (“A Plurality of Pluralisms”), which is that some conceptually essential features of truth are not possessed by the properties usually taken to ground it (such as correspondence and superwarrant), (...) so that Lynch’s account cannot allow truth to be grounded in these properties. In response to this objection, I propose to modify Lynch’s account by restricting the range of truth’s essential features that a truth-grounding property must have to the class of what I call the “bearer-centered” features of truth. They are those features whose possession by truth amounts to certain facts about how propositions bearing truth behave. The resultant account then is that truth is grounded in a property when the latter has all the essential and bearer-centered features of truth. This account is immune to the David–Wright objection because the features they mention do not belong to the class of bearer-centered features. Also, this account is well-motivated by some principled reasons. The account thus serves as a viable functionalist account of truth-grounding. (shrink)

This study examined the effect of fake news on electoral outcome. Using post-election surveys, previous studies found associations between exposure to fake news and voting behavior, though these observational studies failed to show that these changes were actually caused by fake news. To examine whether fake news really affects voting behavior, we need to experimentally manipulate voters’ exposure to fake news in real elections and see if voters regret their vote choice knowing that the information was false. For this purpose, (...) our study focused on Mexico’s 2018 presidential election, which provided an ideal setting. During the campaign, false information about a scandal allegedly involving Ricardo Anaya, a candidate from the National Action Party, was widely disseminated. However, his innocence was officially acknowledged after the election. Using this correction of fake news as a treatment, we tested a sample of 1,561 individuals to assess whether the retraction of fake news caused post-election regret: would Mexican voters have voted differently if they had not been exposed to such false information. Our multivariate analyses found that the retraction of fake news did cause post-election regret among voters with lower internal political efficacy, but voters associated with higher political knowledge and internal political efficacy were not affected by the retraction and were less likely to experience regret. About 20% of the respondents experienced post-election regret, and of those, about 35% would have switched their vote to Anaya. The findings corroborate lasting effects of fake news, which may have non-negligible effects on electoral outcomes. (shrink)

One manifestation of argumentation is in critical discussions where people genuinely strive cooperatively to achieve critical decisions. Hence, argumentation can be recognized as the process of advancing, supporting, modifying, and criticizing claims so that appropriate decision makers may grant or deny adherence. This audience-centered definition holds the assumption that the participants must willingly engage in public debate and discussion, and their arguments must function to open a critical space and keep it open. This essay investigates `ideological pronouncement,' a kind of (...) rhetoric that undermines and limits the possibility of critical discussion among target audiences, as an enemy of sound argumentation. First, the essential characteristics of sound argumentation are explained. Next, the typical characteristics of ideological rhetoric are described. At the same time, the Cardinal Principles of the National Entity of Japan, a Japanese wartime moral education textbook, is examined as a paradigm case of ideological rhetoric. Third, three key pronouncements of the Cardinal Principles are outlined and discussed. Finally, implications from the critical discussion are drawn. (shrink)

To investigate the cognitive processes underlying creative inspiration, we tested the extent to which viewing or copying prior examples impacted creative output in art. In Experiment 1, undergraduates made drawings under three conditions: copying an artist's drawing, then producing an original drawing; producing an original drawing without having seen another's work; and copying another artist's work, then reproducing that artist's style independently. We discovered that through copying unfamiliar abstract drawings, participants were able to produce creative drawings qualitatively different from the (...) model drawings. Process analyses suggested that participants' cognitive constraints became relaxed, and new perspectives were formed from copying another's artwork. Experiment 2 showed that exposure to styles of artwork considered unfamiliar facilitated creativity in drawing, while styles considered familiar did not do so. Experiment 3 showed that both copying and thoroughly viewing artwork executed using an unfamiliar style facilitated creativity in drawing, whereas merely thinking about alternative styles of artistic representation did not do so. These experiments revealed that deep encounters with unfamiliar artworks—whether through copying or prolonged observation—change people's cognitive representations of the act of drawing to produce novel artwork.

There is a familiar tension between the two main components of non-reductive physicalism, which are physicalism, on the one hand, and the non-reducibility or autonomy of so-called special sciences (i.e., sciences other than physics), on the other. While it is often claimed that this tension can be satisfactorily resolved by adopting the subset account of realization (defended by e.g., Shoemaker (2001) and Wilson (2011)), this paper challenges that popular view, by elaborating some critical comments by Funkhouser (2014). Then, after examining (...) Funkhouser’s own position, this paper proposes a new way of resolving the aforementioned tension, which consists in refining the subset account’s analysis of realization on the basis of various dependence relations between causal powers.

This is a review essay on Daisuke Kachi’s recent book, Agents: Contemporary Substance Ontology (sic. Shunjusha, 2018). The book develops and partially defends an ontology that takes the category of substance as the most fundamental one. The author provides in it a new perspective on substance, which consists in characterizing substances as bearers of what he calls “substance modalities” (of which there are four kinds, that stem from the factors of essence, power, past persistence, and future persistence respectively). The first (...) part of this review essay gives an extended overview of Kachi’s book while the second discusses some problems it may face. (shrink)

A number of philosophers today endorse the view that material substances (e.g., cats, stones, atoms) can be analyzed as bundles of “particular properties” or “tropes”. Among several developments, the theory that Peter Simons proposed is seen as the most successful one. Simons’ theory seems to owe its high reputation to mainly two advantages which he claims for his theory: the capacity for avoiding infinite regress, and the explanatory adequacy for the phenomenon of change. In this paper, however, I try to (...) object to this high appraisal, by showing that the two alleged advantages in fact cannot be simultaneously secured by Simons’ position. To this aim, I proceed as follows: First, I present Simons’ theory and explain its alleged two advantages. Next, I take up Arda Denkel’s criticism and show that the explanatory adequacy will be lost unless Simons accepts a certain revision of his theory. Finally, I show that as a result of the revision needed, Simons’ position comes to lose the capacity for avoiding infinite regress in turn. (shrink)

I have given this essay the title: “The Genealogy of Avenging Spirits” after Nietzsche's treatise: “The Genealogy of Morals” (Zur Genealogie der Moral). In this book Nietzsche clarifies the origins and essence of Christian morality which constitutes the basis of European civilization. In a similar fashion I shall endeavor to point out the origins and essence of the concept of avenging spirits which seems to me to form the basis of Japanese civilization.It may seem strange to talk about a concept (...) of avenging spirits. Nevertheless Norinaga Motoori considered mono-noawaré (the melancholy quality of things) the essence of Japanese culture; Daisetsu Suzuki, who was influenced by Zen, related its essence to a conception of Nothingness; and Ruth Benedict related it to the concept of shame as opposed to that of crime. I do not feel that these different opinions which have preceded mine are erroneous, for they undoubtedly capture certain aspects of our culture; however I would venture to say that it is more profoundly influenced by the concept of avenging spirits.
