Homology is a fundamental concept in biology. However, the metaphysical status of homology, especially whether a homolog is a part of an individual or a member of a natural kind, is still a matter of intense debate. The proponents of the individuality view of homology criticize the natural kind view of homology by pointing out that homologs are subject to evolutionary transformation, and natural kinds do not change in the evolutionary process. Conversely, some proponents of the natural kind view of (...) homology argue that a homolog can be construed both as a part of an individual and a member of a natural kind. They adopt the Homeostatic Property Cluster theory of natural kinds, and the theory seems to strongly support their construal. Note that this construal implies the acceptance of essentialism. However, looking back on the history of the concept of homology, we should not overlook the fact that the individuality view was proposed to reject the essentialist interpretation of homology. Moreover, the essentialist notions of natural kinds can, in our view, mislead biologists about the phenomena of homology. Consequently, we need a non-essentialist view of homology, which we name the “persistently reproducible module” view. This view highlights both the individual-like and kind-like aspects of homologs while stripping down both essentialist and anti-essentialist interpretations of homology. In this article, we articulate the PRM view of homology and explain why it is recommended over the other two views. (shrink)

The human environment is currently undergoing massive change amid the rapid adoption of information and communications technology (ICT). ICT can be characterized as offering an opportunity to consider the nature of humanity, create new values, and foster new cultures. As humans, the question that technical innovation relating to Artificial Intelligence (AI) and Robots thrusts before us is, “What is a human?” What exactly are the things that AI will never be able to do, no matter how close it gets to (...) human capabilities? What makes us humans, and what is it that only humans can do? This essay discusses the impact of AI technology on humans and society from the perspective of a turning point in how people perceive themselves and humanity. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Nature (Ziran 自然) of Technological and Economic Development in Early DaoismYumi Suzuki (bio)I. IntroductionEric Nelson's Daoism and Environmental Philosophy: Nourishing Life provides comprehensive guidance on how early and later Daoist thought could offer both ideological and practical solutions to contemporary environmental issues. Nelson does not simple-mindedly claim that Daoists are environmentalists or that Daoism is comparable with modern environmental thought. His monograph has a more sophisticated, and (...) also more ambitious and consequently philosophically provocative, goal: to evolutionally develop old Daoist thought to directly address contemporary philosophical discourses on the environment.1I have summarized elsewhere what I find to be the most significant and meaningful contributions this book has made.2 I think its goal has successfully been achieved in various ways: Nelson gives careful and accurate interpretations to each passage from the original texts.3 What he calls "the new Daoism" deployed on the basis of these interpretations is reasonable and uncontroversial. The monograph overall offers an exemplary model of how wisdom acquired through studying the history of philosophy can be adapted to cogitating on newly emerging philosophical questions, despite differences in the intellectual contexts that we are required to warily distinguish. Moreover, by focusing on the Daoist tradition in East Asia, it well demonstrates how other systems of philosophical thought can be usefully employed to critically reflect on fundamental assumptions that an existing system is already committed to and that could be the very cause of relevant philosophical and pragmatic problems.While I mostly agree with his arguments in chapters 1–4 and 6, the only part I found unsatisfactory is chapter 5, "Early Daoist Biopolitics and a New [End Page 771] Daoist Political Ecology" (pp. 100–118). The present review aims to elaborate reasons for my resistance to Nelson's all-out endorsement of what he regards as the sociopolitical implications of Daoism. When it comes to politics, it appears to me, early Daoist texts such as the Daodejing and the Zhuangzi express often disappointingly ambiguous and agnostic attitudes toward what can be done with respect to their doctrinal opponents and outsiders. My suggestion is that if we examine the explorations of their contenders, that is, mainly Confucians and Legalists, concerning political and technological devices, they may present an altogether less biased and more balanced range of solutions to a question Nelson raises regarding an environmental challenge associated with a competitive globalized economy and rapidly developing technologies in our modern age.II. A Challenge to the Current Environmental MovementChapter 5 begins with the following statement:Appeals to encountering the myriad things in their environmental contexts and relations are necessary for an ecological transformation of existing cultures and societies. Yet an environmental ethos and culture of nature is not sufficient given how systematically reproduced social-economic processes in advanced capitalist societies meditate, entangle, and obstruct the transformative potential of such encounters. To this extent, an adequate environmental philosophy must concurrently be social-political philosophy that can offer an environmentally oriented critique of existing social structures and institutions that directly and indirectly harm creatures and degrade ecosystems in myriad ways such that transformations must transpire in economic and societal structures as well as at the level of individual cultivation and reflections.(p. 100)Nelson maintains that even though it is cardinal to transform the ways in which the myriad things encounter and mutually correspond with each other, as well as alter their own existential state, by cultivating an environmental ethos and culture of nature in each individual and society, one of the most serious challenges for such transformations could originate with already existing capitalist, materialist, and consumerist social structures and institutions widely prevailing and deeply embedded in the highly complex economic and political systems of our age.This, I think, captures the core problem of modern environmentalism. An individual, a group of people such as nonprofit or nongovernmental organizations, or a single city or country might be convinced by the Daoist "biospiritual" mode of life. Nevertheless, it appears to be far more difficult in practice to have certain countries or multinational mega-firms abandon their steadfast, primary commitment to national, industrial, commercial, or corporate missions to pursue their own benefits that deprioritize or...

This paper attempts to reconcile the conceptual conflict between typological and population thinking to provide a philosophical foundation for extended evolutionary synthesis. Typological thinking has been considered a pre-Darwinian, essentialist dogma incompatible with population thinking, which is the core notion of Darwinism. More recent philosophical and historical studies suggest that a non-essentialist form of typology has some advantages in the study of evolutionary biology. However, even if we adopt such an epistemological interpretation of typological thinking, there still remains an epistemological (...) and methodological conflict between these two styles of thinking. How can we relate typological thinking with population thinking in pursuit of more integrated or interconnected research into evolutionary biology? I propose that homology thinking, which is another style of thinking that recognizes homologous characters, provides a common basis for typological representations of character states and for character dynamics in an evolving population. Good examples of this bridging role are found in teratology and breeding, where variation and novelty are recognized in developmental and morphological traits, gene expression patterns, and so on. Essentialism-free, dynamic views of homology have great potential to reconcile typological and population thinking and to set the stage for the EES. (shrink)

This paper is a comparative study of the propositional intuitionistic (non-modal) and classical modal languages interpreted in the standard way on transitive frames. It shows that, when talking about these frames rather than conventional quasi-orders, the intuitionistic language displays some unusual features: its expressive power becomes weaker than that of the modal language, the induced consequence relation does not have a deduction theorem and is not protoalgebraic. Nevertheless, the paper develops a manageable model theory for this consequence and its extensions (...) which also reveals some unexpected phenomena. The balance between the intuitionistic and modal languages is restored by adding to the former one more implication. (shrink)

Japan has often been regarded as an ethnically homogeneous society whose restrictive immigration policies reflect the deep-seated cultural peculiarities of this ‘island nation’. By contrast, I shall argue that Japan’s post- 1945 cultural separation from the other countries of East Asia, and its strict border controls, were to a large extent products of Cold War politics. The postwar democratization of Japan went hand in hand with the introduction of tight restrictions on cross-border mobility: restrictions which had profound consequences for the (...) rights of ethnic minorities in Japan (particularly Koreans and Taiwanese). An exploration of the emergence and impact of this border control regime casts new light, not just on Japan’s role in the Northeast Asian region, but also on key limitations of nation-state centred notions of liberal democracy.

Modal counterparts of intermediate predicate logics will be studied by means of algebraic devise. Our main tool will be a construction of algebraic semantics for modal logics from algebraic frames for predicate logics. Uncountably many examples of modal counterparts of intermediate predicate logics will be given.

In a reenactment, a speaker re-presents or depicts a previously occurring event, often dramatically. In this article we examine the role of gaze in reenactments in conversations from Japanese and American English. Following Goodwin in viewing a reenacted story as ‘a multi-modal, multi-party field of activity’, we show how tellers’ and recipients’ gaze during reenactments is deployed to achieve specific interactional ends. We argue that there are two layers of activities involved in doing reenacting – a) the habitat of the (...) original event; b) the habitat of the reenacting event, including the dynamics of gaining appreciative recipiency – and show how they are interwoven in the joint production of a reenactment.

Shehtman and Skvortsov introduced Kripke bundles as semantics of non-classical first-order predicate logics. We show the structural equivalence between Kripke bundles for intermediate predicate lógics and Kripke-type frames for intuitionistic modal propositional logics. This equivalence enables us to develop the semantical study of relations between intermediate predicate logics and intuitionistic modal propositional logics. New examples of modal counterparts of intermediate predicate logics are given.

Zen and Japanese Culture is one of the twentieth century's leading works on Zen, and a valuable source for those wishing to understand its concepts in the context of Japanese life and art. In simple, often poetic, language, Daisetz Suzuki describes his conception of Zen and its historical evolution. He connects Zen to the philosophy of the samurai, and subtly portrays the relationship between Zen and swordsmanship, haiku, tea ceremonies, and the Japanese love of nature. Suzuki's contemplative work (...) is enhanced by anecdotes, poetry, and illustrations showing silk screens, calligraphy, and examples of architecture. Since its original publication in 1938, this important work has played a major role in shaping conceptions of Zen's influence on Japanese traditional arts. Richard Jaffe's introduction acquaints a new generation of readers with Suzuki's life and career in both Japan and America. Jaffe discusses how Zen and Japanese Culture was received upon its first publication and analyzes the book in light of contemporary criticism, especially by scholars of Japanese Buddhism. (shrink)

The evolutionary origin of consciousness has been a growing area of study in recent years. Nevertheless, there is intense debate on whether the existence of phenomenal consciousness without the cerebral cortex is possible. The corticocentrists have an empirical advantage because we are quasi-confident that we humans are conscious and have the well-developed cortex as the site of our consciousness. However, their prejudice can be an anthropic bias similar to the anthropocentric prejudice in pre-Darwinian natural history. In this paper, I propose (...) three basic principles to provide a conceptual basis for evolutionary studies of consciousness: the non-solipsistic principle, the evolution principle, and the anthropic principle. These principles collectively help us to avoid solipsism, anthropocentrism, and anthropomorphism to some degree, although we cannot be completely free from them. Also, the landscape metaphor associated with the anthropic principle provides an image of how different forms of consciousness can be acquired. (shrink)

This note is a continuation of our former paper ''Complexity of the r-query tautologies in the presence of a generic oracle.'' We give a very short direct proof of the nonexistence of t-generic oracles, a result obtained first by Dowd. We also reconstitute a proof of Dowd's result that the class of all r-generic oracles in his sense has Lebesgue measure one.

Wajsberg and Jankov provided us with methods of constructing a continuum of logics. However, their methods are not suitable for super-intuitionistic and modal predicate logics. The aim of this paper is to present simple ways of modification of their methods appropriate for such logics. We give some concrete applications as generic examples. Among others, we show that there is a continuum of logics (1) between the intuitionistic predicate logic and the logic of constant domains, (2) between a predicate extension ofS4 (...) andS4 with the Barcan formula. Furthermore, we prove that (3) there is a continuum of predicate logics with equality whose equality-free fragment is just the intuitionistic predicate logic. (shrink)

In this paper, we establish the first-order definability of sequents with consistent variable occurrence on bi-approximation semantics by means of the Sahlqvist–van Benthem algorithm. Then together with the canonicity results in Suzuki (2011), this allows us to establish a Sahlqvist theorem for substructural logic. Our result is not limited to substructural logic but is also easily applicable to other lattice-based logics.

The individual physical appearances of robots are considered significant, similar to the way that those of humans are. We investigated whether users prefer robots with male or female physical appearances for use in daily communication situations and whether egalitarian gender role attitudes are related to this preference. One thousand adult men and women aged 20–60 participated in the questionnaire survey. The results of our study showed that in most situations and for most subjects, “males” was not selected and “females” or (...) “neither” was selected. Moreover, the number of respondents who chose “either” was higher than that who chose “female.” Furthermore, we examined the relationship between gender and gender preference and confirmed that the effect of gender on the gender preference for a robot weakened when the human factor was eliminated. In addition, in some situations for android-type robots and in all situations for machine-type robots, equality orientation in gender role attitudes was shown to be higher for people who were not specific about their gender preferences. It is concluded that there is no need to introduce a robot that specifies its gender. Robots with a gender-neutral appearance might be more appropriate for applications requiring complex human–robot interaction and help avoid reproducing a gender bias. (shrink)

A decision maker (DM) selects a project from a set of alternatives with uncertain productivity. After the choice, she observes a signal about productivity and decides how much effort to put in. This paper analyzes the optimal decision problem of the DM who rationally filters information to deal with her post-decision cognitive dissonance. It is shown that the optimal effort level for a project can be affected by unchosen projects in her choice set, and the nature of the choice set-dependence (...) is determined by the signal structure. Some comparative statics of choice set-dependence is also provided. Finally, based on the results, the optimal choice set design is also explored. This paper offers a simple framework to explain the experimental finding in psychology that people’s effort level for a project can be enhanced when the project is chosen by themselves rather than by others.

When an agent’s motivation is sensitive to how his supervisor thinks about the agent’s competence, the supervisor has to take into account both informational and expressive contents of her message to the agent. This paper shows that the supervisor can credibly express her trust in the agent’s ability only by being un- clear about what to do. Suggesting what to do, i.e., “directives,” could reveal the supervisor’s “distrust” and reduce the agent’s equilibrium effort level even though it provides useful information (...) about the decision environment. There is also an equilibrium in which directives are neutral in expressive content. However, it is shown that neologism proofness favors equilibria in which directives are double- edged swords.

This paper presents a cross-cultural study on peoples’ negative attitude toward robots. 467 participants from seven different countries filled in the negative attitude towards robots scale survey which consists of 14 questions in three clusters: attitude towards the interaction with robots, attitude towards social influence of robots and attitude towards emotions in interaction with robots. Around one half of them were recruited at local universities and the other half was approached through Aibo online communities. The participants’ cultural background had a (...) significant influence on their attitude and the Japanese were not as positive as stereotypically assumed. The US participants had the most positive attitude, while participants from Mexico had the most negative attitude. The participants from the online community were more positive towards robots than those not involved. Previous experience in interacting with Aibo also had a positive effect, but owning an Aibo did not improve their attitude. (shrink)

Since sending explicit messages can be costly, people often utilize “what is not said,” i.e., informative silence, to economize communication. This paper studies the efficient communication rule, which is fully informative while minimizing the use of explicit messages, in cooperative environments. It is shown that when the notion of context is defined as the finest mutually self-evident event that contains the current state, the efficient use of informative silence exhibits the defining property of indexicals in natural languages. While the efficient (...) use of silence could be complex, it is also found that the efficient use of silence can be as “simple” as the use of indexicals in natural languages if and only if the information structure satisfies some centrality and dominance properties.

One criterion of constructive logics is the disjunction, property (DP). The Halldén-completeness is a weak DP, and is related to the relevance principle and variable separation. This concept is well-understood in the case of propositional logics. We extend this notion to predicate logics. Then three counterparts naturally arise. We discuss relationships between these properties and meet-irreducibility in the lattice of logics.

This paper studies a sender-receiver game in which both players want the receiver to choose the state-optimal action. Before observing the state, the sender observes a “contextual signal,” a payoff-irrelevant signal that correlates with states and is imperfectly shared with the receiver. Once the sender observes the state, the sender sends a message to the receiver, incurring a small messaging cost. It is shown that there is no miscommunication in any efficient equilibrium if the messaging cost is uniform or contextual (...) information is poorly shared between players. However, if the messaging costs are different between some messages, and contextual information can affect the probability ranking of states and is shared reasonably well, any efficient equilibrium that favors the sender exhibits miscommunication. Furthermore, the messages that cause miscommunication can be coarse or ambiguous, depending on how well players share contextual information. (shrink)

No segundo livro das Ideias para uma fenomenologia, Husserl introduz pela primeira vez a noção de mundo da vida (Lebenswelt) para descrever o que até então era o solo originário da gênese do sentido. Nas Investigações lógicas, ao descrever os jogos de linguagem, Wittgenstein trabalha com a ideia de que estes são formas de vida (Lebensformen). Sem pretender ser exaustiva, esta nota procura discutir sucintamente o que se entende pelo termo vida nos dois casos, para mostrar que a correlação estrita (...) do bíos com o lógos não inclui exatamente uma compreensão biológica do conceito. A primeira parte tratará de discutir a questão no segundo Wittgenstein; a segunda estará dedicada à ontologia fundamental de Husserl. (shrink)

The vestibulo-ocular reflex plays an important role in controlling the gaze at a visual target. Although patients with vestibular hypofunction aim to improve their VOR function, some retain dysfunction for a long time. Previous studies have explored the effects of direct current stimulation on vestibular function; however, the effects of random noise stimulation on eye–head coordination have not previously been tested. Therefore, we aimed to clarify the effects of high frequency noisy vestibular stimulation on eye–head coordination related to VOR function. (...) Thirteen healthy young adult participants with no serious disease took part in our study. The current amplitude and density used were 0.4 mA and 0.2 mA/cm2, respectively, with a random noise frequency of 100–640 Hz. The electrodes were located on both mastoid processes. The stimulus duration and fade in/out duration were 600 and 10 s, respectively. Subjects oscillated their head horizontally, gazing at the fixation point, at 1 Hz for 30 repetitions. The coordination of eye–head movements was measured by eye-tracking and a motion capture system. Peak-to-peak angles for eye and head movement and deviation of the visual line from the fixation target revealed no significant differences between HF-nVS and sham. The lag time between the eye and head movement with HF-nVS post-stimulation was significantly shorter than that of the sham. We found that HF-nVS can reduce the lag time between eye and head movement and improve coordination, contributing to a clear retinal image. This technique could be applied as a form of VOR training for patients with vestibular hypofunction. (shrink)
