Feinberg and Mallatt, in their presentation of neurobiological naturalism, have suggested that visual consciousness was acquired by early vertebrates and inherited by a wide range of descendants, and that its neural basis has shifted to nonhomologous nervous structures during evolution. However, their evolutionary scenario of visual consciousness relies on the assumption that visual consciousness is closely linked with survival, which is not commonly accepted in current consciousness research. We suggest an alternative idea that visual consciousness is linked to a specific (...) class of agency, consequently justifying their phylogenetic claim. We also examine the implication of their phylogenetic claim: visual consciousness is homologous across vertebrates, but its neural basis is not. This apparent incongruence illustrates a general phenomenon of homology, and that the resulting hierarchical view of visual consciousness and its neural basis can be straightforwardly accommodated by neurobiological naturalism. Throughout these discussions, we aim to address the potential theoretical issues in neurobiological naturalism and refine the picture illustrated by Feinberg and Mallatt regarding phylogenetic distribution and trajectories of visual consciousness.

La figure diabolisée du chat dans la littérature japonaise évolue sans cesse au cours de l’époque médiévale, et nous prenons ici l’exemple d’un chat-monstre nommé nekomata. L’un des exemples littéraires les plus connus se trouve dans les Heures oisives, ouvrage écrit vers 1330 par Yoshida Kenkô. Il semble cependant que le terme nekomata soit apparu un siècle plus tôt, comme le montre l’entrée du 2 août 1233 dans le Journal de la lune brillante de Fujiwara no Teika, l’un des plus (...) grands poètes de son temps. Nous analyserons donc ce texte de première importance pour comprendre les origines de cette figure littéraire, puis tenterons de comprendre le sens de l’expression nekomata. The demonized figure of the cat in Japanese literature evolved constantly during medieval times, and here we take the example of a monster cat named nekomata. One of the best-known literary examples is found in Tsurezure-gusa, written around 1330 by Yoshida Kenkô. However, it seems that the term nekomata appeared a century earlier, as can be seen from the August 2, 1233 entry in Meigetsu-ki, the diary of Fujiwara no Teika, one of the greatest poets of his time. We will examine this important text for a better understanding of the history of the monster cat and reflect on the meaning of the term nekomata. (shrink)

La figure du chat fait son apparition dans la littérature japonaise au ixe siècle, mais son image évoluera de manière inattendue à l’époque médiévale. Des témoignages littéraires du xie et du xiie siècle, tels que les Notes de chevet de Sei Shônagon et Le Dit du Genji de Murasaki Shikibu, montraient clairement l’intérêt porté aux chats par les dames de cour. Pourtant, à partir du xiiie siècle, le félidé fera au contraire l’objet d’une forme de « diabolisation », et c’est (...) cette dimension plus inquiétante du chat que nous aimerions évoquer ici, à travers trois exemples tirés du Kokon chomon-jû, vaste recueil de contes et légendes. Cette œuvre méconnue en Europe est attribuée à Tachibana no Narisue et achevée en 1254. The figure of the cat made its appearance in Japanese literature in the 9th century, but its image evolved unexpectedly in medieval times. Literary evidence from the 11th and 12th centuries, such as the Bedside Notes by Sei Shônagon and The Tale of Genji by Murasaki Shikibu clearly showed the interest of court women in cats. However, from the 13th century, the feline became the object of a form of “demonization”, and it is this more disturbing dimension of the cat that we would like to describe here, through three examples taken from Kokon chomon-Jû, a vast collection of tales and legends. This work, unknown in Europe, has been attributed to Tachibana no Narisue and was completed in 1254. (shrink)

We propose a new information sharing system, named ``BisNet'', which automatically gathers information about the bookmarks stored in users' web browsers and helps the users exchange URIs of possibly interesting web pages with others who have similar interest with them. Being different from other typical agent services that gather and provide information according to pre-registered user profiles, BisNet is expected to share more relevant information because of its use of web browser bookmarks that are actively selected and ordered by many (...) humans. To enhance the relevance of information being shared, we developed a novel algorithm for directory evaluation. This algorithm only looks at the local referential structure between bookmark directories and URIs and calculates for each directory the ``order index'' that represents how well its content URIs are put in order with a focus on specific areas of interest. Then each directory receives new URIs from other related directories with large order indexes. The repetition of such URI exchanges makes the whole directory-URI networks dynamically form directory groups according to the commonness of the URIs they refer to. Our method is unique in that it pays no attention to the actual contents of web pages, and thus is much simpler and faster than other methods based on the result of content analysis. We carried out a field trial that involved 45 people who used a prototype version of BisNet clients. The result indicated that the relevance of shared URIs positively correlated with the ``order index'' of surrounding related directories, demonstrating the effectiveness of the method we proposed.

One of the prime characteristics of the increasingly technological and interconnected world is the disappearance of analogue experience in all aspects of life. Due to technological invention, we are exposed to a variety of news and information, checking emails in private and business accounts for a significant amount of time each day.

The moral status of human brain organoids (HBOs) has been debated in view of the future possibility that they may acquire phenomenal consciousness. This study empirically investigates the moral sensitivity in people’s intuitive judgments about actions toward conscious HBOs. The results showed that the presence/absence of pain experience in HBOs affected the judgment about the moral permissibility of actions such as creating and destroying the HBOs; however, the presence/absence of visual experience in HBOs also affected the judgment. These findings suggest (...) that people’s intuitive judgments about the moral status of HBOs are sensitive to the valence-independent value of phenomenal consciousness. We discuss how these observations can have normative implications; particularly, we argue that they put pressure on the theoretical view that the moral status of conscious HBOs is grounded solely in the valence-dependent value of consciousness. We also discuss how our findings can be informative even when such a theoretical view is finally justified or when the future possibility of conscious HBOs is implausible. (shrink)

In this paper, we argue that a distinction ought to be drawn between two ways in which a given world might be logically impossible. First, a world w might be impossible because the laws that hold at w are different from those that hold at some other world (say the actual world). Second, a world w might be impossible because the laws of logic that hold in some world (say the actual world) are violated at w. We develop a novel (...) way of modelling logical possibility that makes room for both kinds of logical impossibility. Doing so has interesting implications for the relationship between logical possibility and other kinds of possibility (for example, metaphysical possibility) and implications for the necessity or contingency of the laws of logic.

This paper considers the computational complexity of the design of voting rules, which is formulated by simple games. We prove that it is an NP-complete problem to decide whether a given simple game is stable, or not.

In this paper, we describe a collaborative information retrieval method among personal repositorie and an implementation of the method on a personal agent framework. We propose a framework for personal agents that aims to enable the sharing and exchange of information resources that are distributed unevenly among individuals. The kernel of a personal agent framework is an RDF(resource description framework)-based information repository for storing, retrieving and manipulating privately collected information, such as documents the user read and/or wrote, email he/she exchanged, (...) web pages he/she browsed, etc. The repository also collects annotations to information resources that describe relationships among information resources and records of interaction between the user and information resources. Since the information resources in a personal repository and their structure are personalized, information retrieval from other users' is an important application of the personal agent. A vector space model with a personalized concept-base is employed as an information retrieval mechanism in a personal repository. Since a personalized concept-base is constructed from information resources in a personal repository, it reflects its user's knowledge and interests. On the other hand, it leads to another problem while querying other users' personal repositories; that is, simply transferring query requests does not provide desirable results. To solve this problem, we propose a query equalization scheme based on a relevance feedback method for collaborative information retrieval between personalized concept-bases. In this paper, we describe an implementation of the collaborative information retrieval method and its user interface on the personal agent framework. (shrink)

Proof-theory has traditionally been developed based on linguistic (symbolic) representations of logical proofs. Recently, however, logical reasoning based on diagrammatic or graphical representations has been investigated by logicians. Euler diagrams were introduced in the eighteenth century. But it is quite recent (more precisely, in the 1990s) that logicians started to study them from a formal logical viewpoint. We propose a novel approach to the formalization of Euler diagrammatic reasoning, in which diagrams are defined not in terms of regions as in (...) the standard approach, but in terms of topological relations between diagrammatic objects. We formalize the unification rule, which plays a central role in Euler diagrammatic reasoning, in a style of natural deduction. We prove the soundness and completeness theorems with respect to a formal set-theoretical semantics. We also investigate structure of diagrammatic proofs and prove a normal form theorem. (shrink)

This paper gives new confluence proofs for several lambda calculi with permutation-like reduction, including lambda calculi corresponding to intuitionistic and classical natural deduction with disjunction and permutative conversions, and a lambda calculus with explicit substitutions. For lambda calculi with permutative conversion, naïve parallel reduction technique does not work, and traditional notion of residuals is required as Ando pointed out. This paper shows that the difficulties can be avoided by extending the technique proposed by Dehornoy and van Oostrom, called the Z (...) theorem: existence of a mapping on terms with the Z property concludes the confluence. Since it is still hard to directly define a mapping with the Z property for the lambda calculi with permutative conversions, this paper extends the Z theorem to compositional functions, called compositional Z, and shows that we can adopt it to the calculi.

The paper is concerned with the development of the paradoxical theme of Daoism. Based on Chad Hansen's interpretation of Daoism and Chinese philosophy in general, it traces the history of Daoism by following their treatment of the limit of language. The Daoists seem to have noticed that there is a limit to what language can do and that the limit of language is paradoxical. The 'theoretical' treatment of the paradox of the limit of language matures as Daoism develops. Yet the (...) Daoists seem to have noticed that the limit of language and its paradoxical nature cannot be overcome. At the end, we are left with the paradoxes of the Daoists. In this paper, we jump into the abyss of the Daoists' paradoxes from which there is no escape. But the Daoists' paradoxes are fun! (shrink)

This paper applies Dehornoy et al.’s Z theorem and its variant, called the compositional Z theorem, to prove confluence of Parigot’s \-calculi extended by the simplification rules. First, it is proved that Baba et al.’s modified complete developments for the call-by-name and the call-by-value variants of the \-calculus with the renaming rule, which is one of the simplification rules, satisfy the Z property. It gives new confluence proofs for them by the Z theorem. Secondly, it is shown that the compositional (...) Z theorem can be applied to prove confluence of the call-by-name and the call-by-value \-calculi with both simplification rules, the renaming and the \-rules, whereas it is hard to apply the ordinary parallel reduction technique or the original Z theorem by one-pass definition of mappings for these variants.

This study examines Japanese reactions to neighboring countries’ behavior by addressing possible micro-motives, such as patriotism, the rational demand for national defense, and retrospective policy evaluation. This theoretical development leads to distinctive hypotheses from different motivations and directly tests them using macro-data . This research will apply this framework to Japanese politics and will show that foreign threats stimulate patriotism in the public mind and enhance political support for national leaders. It will also demonstrate that the Japanese public has no (...) optimistic view of the new prime minister and that the honeymoon effect in previous research may be confounded with the patriotic effect because the new leader is less experienced and is often challenged by foreign countries.

This paper gives the strong reduction of the combinatory calculus SCL, which was introduced as a combinatory calculus corresponding to the untyped Lambda-mu calculus. It proves the confluence of the strong reduction. By the confluence, it also proves the conservativity of the extensional equality of SCL over the combinatory calculus CL, and the consistency of SCL.

Human space exploration requires massive budgets every fiscal year. Especially under severe financial constraint conditions, governments are forced to justify to society why spending so much tax revenue for human space exploration is worth the cost. The value of human space exploration might be estimated in many ways, but its social significance and cost-effectiveness are two key ways to gauge that worth. Since these measures should be applied country by country because sociopolitical conditions differ in each country and must be (...) taken into consideration, the study on the social significance of human space exploration must take the coloration of a case-study. This paper, focusing on the case of Japan with surveying Japanese literary and national documents as well as taking its sociopolitical conditions into account, examines the social significance of human space exploration. -/- First, we give an overview of the circumstances surrounding Japan's human space exploration program. Derived from the statements of such relevant parties as scholars, journalists, policy makers, and astronauts, this overview indicates that the main concerns about human space exploration in Japan are its social significance and cost-effectiveness (Section 1). Next, an overview of behavioral science—an essential field for human space exploration (referred to in this paper as space behavioral science) that provides support for astronauts—is presented from the perspective of stress research in isolated and confined environments (Section 2). We then give two examples of where such knowledge from space behavioral science research has been applied to terrestrial isolated and confined environments. One is JAXA’s support in 2009 for people who were vulnerable to infection by a new strain of flu and accordingly placed in an isolated and confined facility under the Infectious Disease Law and the Quarantine Law. The other is NASA's support in 2010 for Chilean mine workers who were trapped 700 m underground after a mining accident (Section 3). Based on these case studies, we illustrate the further social utility of such knowledge through a discussion of potential applications in other situations in Japan. Focusing on Japan for its geographical and social features in being an earthquake-prone archipelago and having the world's preeminent aging society, we show that refugees living in evacuation centers and people in an elderly-elderly homecare situation pose socially problematic situations specific to Japan. We then argue that space behavioral scientific knowledge can be applied to support people under these and other isolated and confined environments in various ways (Section 4). Finally, we demonstrate that such an application can be understood as an ethical contribution to Japanese society and that this contribution can be embedded in Japan's space policy (Section 5). We conclude that human space exploration can be a socially significant and cost-effective endeavor that is worthy of tax revenue expenditures because space behavioral science is highly likely to provide unique and useful knowledge to help address various social problems concerning terrestrial isolated and confined environments and support people in sufferings there.

Max Cresswell and Hilary Putnam seem to hold the view, often shared by classical logicians, that paraconsistent logic has not been made sense of, despite its well-developed mathematics. In this paper, I examine the nature of logic in order to understand what it means to make sense of logic. I then show that, just as one can make sense of non-normal modal logics (as Cresswell demonstrates), we can make `sense' of paraconsistent logic. Finally, I turn the tables on classical logicians (...) and ask what sense can be made of explosive reasoning. While I acknowledge a bias on this issue, it is not clear that even classical logicians can answer this question. (shrink)

There was a time when 'logic' just meant classical logic. The climate is slowly changing and non-classical logic cannot be dismissed off-hand. However, a metatheory used to study the properties of non-classical logic is often classical. In this paper, we will argue that this practice of relying on classical metatheories is problematic. In particular, we will show that it is a bad practice because the metatheory that is used to study a non-classical logic often rules out the very logic it (...) is designed to study. (shrink)

What does it mean for the laws of logic to fail? My task in this paper is to answer this question. I use the resources that Routley/Sylvan developed with his collaborators for the semantics of relevant logics to explain a world where the laws of logic fail. I claim that the non-normal worlds that Routley/Sylvan introduced are exactly such worlds. To disambiguate different kinds of impossible worlds, I call such worlds logically impossible worlds. At a logically impossible world, the laws (...) of logic fail. In this paper, I provide a definition of logically impossible worlds. I then show that there is nothing strange about admitting such worlds. (shrink)

Frankfurt-Style Cases (FSCs) seem to elicit the intuitive judgment that an agent is morally responsible despite being unable to act otherwise, which is supposed to falsify the Principle of Alternative Possibility (PAP). Recent empirical studies have shown that the inclination toward this intuitive judgment is shared among people, which seems to reinforce the argument against the PAP. However, some scholars have argued for Descriptive Anti-Intuitionism (DAI) — intuitive judgments have never played an evidential role in philosophy — and thus denied (...) the philosophical significance of such empirical findings. I point out that although DAI fails in its literal claim for FSCs, an associated insight remains potent: an intuitive judgment is so fragile that it can be easily defeated by further arguments. Nevertheless, I argue, empirical studies are significant in uncovering the general principles to which we are committed in our practice concerning moral responsibility. I clarify how such findings can play a robust evidential role in philosophical debates concerning moral responsibility by tracing the literature written by Frankfurt and philosophers. (shrink)

The problem of how to accommodate inconsistencies has attracted quite a number of researchers, in particular, in the area of database theory. The problem is also of concern in the study of belief change. For inconsistent beliefs are ubiquitous. However, comparatively little work has been devoted to discussing the problem in the literature of belief change. In this paper, I examine how adequate the AGM theory is as a logical framework for belief change involving inconsistencies. The technique is to apply (...) to Grove’s sphere system, a semantical representation of the AGM theory, logics that do not infer everything from contradictory premises, viz., paraconsistent logics. I use three paraconsistent logics and discuss three sphere systems that are based on them. I then examine the completeness of the postulates of the AGM theory with respect to the systems. At the end, I discuss some philosophical implications of the examination. (shrink)

Logic in Buddhist Philosophy concerns the systematic study of anumāna (often translated as inference) as developed by Dignāga (480-540 c.e.) and Dharmakīti (600-660 c.e.). Buddhist logicians think of inference as an instrument of knowledge (pramāṇa) and, thus, logic is considered to constitute part of epistemology in the Buddhist tradition. According to the prevalent 20th and early 21st century ‘Western’ conception of logic, however, logical study is the formal study of arguments. If we understand the nature of logic to be formal, (...) it is difficult to see what bearing logic has on knowledge. In this paper, by weaving together the main threads of thought that are salient in Dignāga’s and Dharmakīti’s texts, I shall re-conceive the nature of logic in the context of epistemology and demarcate the logical part of epistemology which can be recognised as logic. I shall demonstrate that we can recognise the logical significance of inference as understood by Buddhist logicians despite the fact that its logical significance lies within the context of knowledge.

In the 1958-1959 Collège de France course, Merleau-Ponty expounds a detailed commentary on the last paragraphs of the Einleitung from Hegel’s Phenomenology of Spirit. We examine in what sense this course has developed the notions that he was in the process of defining, notions such as “chiasm,” “reversibility,” “depth,” and “flesh.” What seems crucial in this course is to clearly define good ambiguity as opposed to bad ambiguity, that is, to the simple mixture of finitude and universality, of interiority and (...) exteriority. It is a question then of revealing, even within Hegelian thought, the operation, although unstable, of good ambiguity and of instituting it beyond the distinction between anthropology and logic without a return to naturalism. It should first be noted that consciousness is for Hegel violence against itself, it gives itself its measure, such that the distinction between measuring and measured is internal to it. By insisting on this “reversibility” of the measuring and the measured, Merleau-Ponty comes to emphasize that the self-relation of consciousness is simultaneously its opening onto a transcendent – an opening whereby it learns something. This leads him to define “the new ontological milieu” which is the depth of the life of consciousness. It is within this depth that the interrogative experience winds on itself. Secondly, if there truly must be a moment where the Hegelian Zweideutigkeit becomes good ambiguity, it will not suffice to explore preobjective depth; it would still be necessary to discern “the hinge” which is “solid, unwavering” and which “remains irremediably hidden.” It is this unwavering hinge that supports phenomena and that, in simultaneously decentering and recentering the fields of appearances, opens a place where one can follow the genesis of sense. Finally, we note that this discovery of the new ontological milieu can be considered as the recovery of the notion of institution that Merleau-Ponty had proposed in 1954-1955: on the one hand, the notion of chiasm invites us to reveal the hinge which at once decenters and recenters the fields of appearances. This hinge is free from the alternative of nature and culture, of subjective and objective spirit; it is the rootedness of our interrogative experience in brute being, which is not object but starts an indefinite search of self. But, on the other hand, the notion of institution, which is essentially descriptive and factual, makes us better feel the weight of the instituted that is also irremediably hidden. It makes us feel the inertia of the instituting event, as well as its fecundity and its cumulativity. (shrink)
