The present study assesses imitative ability in chimpanzees and human children. A direct comparison of these two species was conducted in an object-manipulation task. The subjects were required to copy the model stack by stacking colored blocks in the same order as the model. Four juvenile/adolescent chimpanzees failed to copy the model stack even after a long training-period. Two adult chimpanzees eventually learned to copy the model stack of two blocks. However, they failed to copy the model of three blocks, (...) and analysis of their stacking patterns revealed that they only focused on the color of the top block in the model. Human children started to copy the model of two blocks when they were two years of age and gradually increased the number of successfully copied blocks. The results from both chimpanzees and humans are discussed in terms of the social intelligence involved in object manipulation. (shrink)

The evolution of altruism and reciprocity has been explained mainly from ultimate perspectives. However, in order to understand from a proximate perspective how humans evolved to be such cooperative animals, comparative studies with our evolutionary relatives are essential. Here we review several recent experimental studies on chimpanzees’ altruism and reciprocity. These studies have generated some conflicting results. By examining the differences in the results and experimental paradigms, two characteristics of prosociality in chimpanzees emerged: chimpanzees are more likely to behave altruistically (...) and/or reciprocally upon a recipient’s request, than without request, and chimpanzees also show a tendency to regard others and help in contexts not involving food. Supposing that these two characteristics of altruism, recipient-initiated altruism and non-food altruism, were present in the common ancestor of chimpanzees and humans, it is possible that increased social cognitive abilities, capacity for language, necessity for food sharing, and enriched material culture favored in humans the unique evolution of cooperation, characterized by voluntary altruism and frequent food donation.

In his book review of Graham Priest's The Fifth Corner of Four, Mark Siderits, while criticising Priest's philology, suggests that Priest's work is 'of considerable interest' for two reasons. First, 'when two independent traditions use similar methods to work on similar issues, it is always possible that one may have hit on approaches that the other missed'. Second, 'the decentering that can be induced by looking at another tradition may trigger fresh insights, even if those insights are not ones that (...) were actually developed by the tradition marked 'other''. The main task of this paper is to unpack Siderits' thought. By analysing some of Priest's work, I will suggest a decentering that must have taken place in China when Buddhism was 'exported to China in Buddhist shipping containers'. For anyone familiar with the forms of Buddhist philosophy developed in India, various forms of Chinese Buddhism can often look strange. Some ideas that were debated and defended by Indian Buddhists do not appear anywhere in Chinese Buddhism and some assumptions have been quietly added to Buddhism by Chinese Buddhists. By showing that Priest's work brings out the 'innovation' that Chinese Buddhists gave to Buddhism, I will suggest that it is this decentering that Siderits suggests Priest makes use of. (shrink)

In this paper, we propose an extension of the Minimal Generation Gap (MGG) to reduce the number of fitness evaluation for the real-coded GAs (RCGA). When MGG is applied to actual engineering problems, for example applied to optimization of design parameters, the fitness calculating time is usually huge because MGG generates many children from one pair of parents and the fitness is calculated by repetitive simulation or analysis. The proposed method called Saving MGG reduces the number of fitness evaluation by (...) estimating the promising degrees of children using individual distribution and fitness information of population, and selecting children based on the promising degree before evaluating the fitness. Experimental results show that RCGA with Saving MGG can provide large reducing effects on 20 or 30 dimensional Sphere functions, Rosenbrock functions, ill-scaled Rosenbrock functions, and Rastrigin function.

It is known that for any subdirectly irreducible finite Heyting algebra A and any Heyting algebra, B, A is embeddable into a quotient algebra of B, if and only if Jankov's formula ${\rm{\chi A}}$ A for A is refuted in B.

More precisely, for any cardinal number ${\rm{\kappa }}$, we present Jankov's theorem for homomorphisms preserving infinite meets and joins, a class of subdirectly irreducible complete (...) ${\rm{\kappa }}$ - Heyting algebras and ${\rm{\kappa }}$ - infinitary logic, where a ${\rm{\kappa }}$ -Heyting algebra is a Heyting algebra A with ${\rm{\# A}} \le {\rm{\kappa }}$ and ${\rm{\kappa }}$ - infinitary logic is the infinitary logic such that for any set ${\rm{\Theta }}$ of formulas with ${\rm{\# \Theta }} \le {\rm{\kappa }}$ ⌈ Θ and ‷ Θ are well defined formulas.

Recent studies have identified two important findings on infants’ capability of taking others’ perspectives and the difficulty of ignoring perspectives irrelevant to the acquired perspective. Unfortunately, there is insufficient consensus on the interpretation of these phenomena. Two important features of perspective-taking, embodiment and aging, should be considered to reach a more appropriate hypothesis. In this paper, the mechanism of perspective-taking can be redefined through the well-known process of self–other distinction, which is inherent to humans, without resorting to either the assumption (...) of controversial systems or an excessive reduction to executive functions. Therefore, it is hypothesized that the implicit mentalizing observed in infancy comes from the loosening phenomenon and lasts lifelong and that the self-representation separated from one’s own body by the detachment function is sent to other perspectives for explicit perspective-taking. This hypothesis can not only explain both the robustness of perspective-taking in the older adults and the appearance of egocentric/altercentric bias in adults but also is consistent with the findings in brain science and neuropathology. Finally, some issues to be considered are presented to improve the validity of this hypothesis. (shrink)

Kripke completeness of some infinitary predicate modal logics is presented. More precisely, we prove that if a normal modal logic above is -persistent and universal, the infinitary and predicate extension of with BF and BF is Kripke complete, where BF and BF denote the formulas pi pi and x x, respectively. The results include the completeness of extensions of standard modal logics such as , and its extensions by the schemata T, B, 4, 5, D, and their combinations. The proof (...) is obtained by extending the correspondence between the representation of modal algebras and the completeness of propositional modal logic to infinite. (shrink)

The recognition and extraction of semantic/logical structures in HTML documents are substantially important and difficult tasks for intelligent document processing. In this paper, we show that the alignment technology is an appropriate tool, within a framework of case-based reasoning, for recognizing semantic structures inherently embedded in a series of HTML documents. That is, given a series of HTML documents and a document example of which semantic structures are explicitly indicated by a user, then the alignment can identify semantic structures in (...) the HTML document series, by matching a text-block sequence in each HTML document with the text-block sequence in the example document. Several important properties in text documents, such as continuity, sequentiality of texts, can be treated by the alignment in a quite natural way. The alignment technology can significantly improve the capability of the case-based transformation method which transforms a spatial and/or temporal series of HTML documents into machine-readable XML formats. Moreover, the alignment dramatically eases the construction of transformation exmaples. Throughout experimental evaluation for 47 pages of 8 series of HTML documents, we show that the case-based method using the alignment achieved a highly accurate transformation into XML formats.

Cultures are constituted by binary oppositions: the absolute and the relative; the perfect and the imperfect; the stable and the unstable. Many of the world’s cultures have looked to revealed religion to discover the absolute: that which transcends the human, the intellect, and space and time. By positing a God who is omniscient and omnipotent, they conceive of an eternal and absolute that continues to exist in an immutable state.In such cultures new perspectives for reinterpreting the past are continually propounded. (...) This allows history to be rewritten and re-rewritten. History simply becomes a method for becoming conscious of the past.By contrast, many East Asian cultures have not developed such a concept of revealed religion. For them, history itself constitutes an absolute, something on which one can rely. History in East Asia is endowed with a normative function, a source of authority that does not permit easy rewriting. (shrink)

All surviving jawed vertebrate representatives achieve diversity in immunoglobulin‐based B and T cell receptors for antigen recognition through recombinatorial rearrangement of V(D)J segments. However, the extant jawless vertebrates, lampreys and hagfish, instead generate three types of variable lymphocyte receptors (VLRs) through a template‐mediated combinatorial assembly of different leucine‐rich repeat (LRR) sequences. The clonally diverse VLRB receptors are expressed by B‐like lymphocytes, while the VLRA and VLRC receptors are expressed by lymphocyte lineages that resemble αβ and γδ T lymphocytes, respectively. These (...) findings suggest that three basic types of lymphocytes, one B‐like and two T‐like, are an essential feature of vertebrate adaptive immunity. Around 500 million years ago, a common ancestor of jawed and jawless vertebrates evolved a genetic program for the development of prototypic lymphoid cells as a foundation for an adaptive immune system. This acquisition preceded the convergent evolution of alternative types of clonally diverse receptors for antigens in all vertebrates, as reviewed in this article. (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.

A logic is called 'paraconsistent' if it rejects the rule called 'ex contradictione quodlibet', according to which any conclusion follows from inconsistent premises. While logicians have proposed many technically developed paraconsistent logical systems and contemporary philosophers like Graham Priest have advanced the view that some contradictions can be true, and advocated a paraconsistent logic to deal with them, until recent times these systems have been little understood by philosophers. This book presents a comprehensive overview on paraconsistent logical systems to change (...) this situation. The book includes almost every major author currently working in the field. The papers are on the cutting edge of the literature some of which discuss current debates and others present important new ideas. The editors have avoided papers about technical details of paraconsistent logic, but instead concentrated upon works that discuss more 'big picture' ideas. Different treatments of paradoxes takes centre stage in many of the papers, but also there are several papers on how to interpret paraconistent logic and some on how it can be applied to philosophy of mathematics, the philosophy of language, and metaphysics.

An assessment of mood or emotion is important in developing mental health measures, and facial expressions are strongly related to mood or emotion. This study thus aimed to examine the relationship between levels of negative mood and characteristics of mouth parts when moods are drawn as facial expressions on a common platform. A cross-sectional study of Japanese college freshmen was conducted, and 1,068 valid responses were analyzed. The questionnaire survey consisted of participants’ characteristics, the Profile of Mood States, and a (...) sheet of facial expression drawing, and the sheet was digitized and analyzed using an image-analysis software. Based on the total POMS score as an index of negative mood, the participants were divided into four groups: low, normal, high, and very high. Lengths of drawn lines and between both mouth corners were significantly longer, and circularity and roundness were significantly higher in the L group. With increasing levels of negative mood, significant decreasing trends were observed in these lengths. Convex downward and enclosed figures were significantly predominant in the L group, while convex upward figures were significantly predominant and a tendency toward predominance of no drawn mouths or line figures was found in the H and VH groups. Our results suggest that mood states can be significantly related to the size and figure characteristics of drawn mouths of FACED on a non-verbal common platform. That is, these findings mean that subjects with low negative mood may draw a greater and rounder mouth and figures that may be enclosed and downward convex, while subjects with a high negative mood may not draw the line, or if any, may draw the line shorter and upward convex.

Dharmakīrti argues that there is no pramāṇa (valid means of cognition or source of knowledge) for a thesis that is a self-contradiction (svavacanavirodha). That is, self-contradictions such as ‘everything said is false’ and ‘my mother is barren’ cannot be known to be true or false. The contemporary scholar Tillemans challenges Dharmakīrti by arguing that we can know that self-contradictions are false by means of a formal logical inference. The aims of the paper are to answer Tillemans’ challenge from what we (...) take to be Dharmakīrti’s or Dharmakīrtian (someone who is like Dharmakīrti) perspective and to demonstrate the unique features of Dharmakīrti’s view of inference. By so doing, we show that the epistemology in relation to the formal conception of logic that underlies Tillemans’ challenge is problematic from Dharmakīrti’s or Dharmakīrtian perspective. The paper, thus, presents Dharmakīrti’s view of inference and logical reasoning as well as a Dharmakīrtian challenge to the formal conception of logic that is the dominant contemporary conception.

Narrative views of the self argue that we constitute our self in self-narratives. Embodied views hold that our self is shaped through embodied experiences. In that case, what is the relation between embodiment and narrativity in the process of self-constitution? The question demands a clear definition of embodiment, but existing studies remains unclear on this point (section 2). We offer a correction to this situation by drawing on Merleau-Ponty’s analysis of the body that highlights its habituality. On this account, the (...) body has an inherent tendency to cultivate an organization of habits through its history of engagement with the world (section 3). Next, we explore its role in narrative self-constitution by distinguishing between two aspects of the narrative self, the narrated I and the narrating I (section 4). We argue on phenomenological grounds that self-narratives are informed by bodily perspectives in both respects. Furthermore, a focus on the habituality of the body allows for a better explanation of self-constitution than those based on implicit self-narratives (section 5). For these phenomenological and theoretical reasons, we conclude that narrative self-constitution is an embodied and embedded practice (section 6). (shrink)

◎ 以政治思想使的角度切入，完整剖析荀子的政治思想淵源、構造及特色。 ◎ 闡明荀子如何將早期儒、墨的倫理論辯，提升為分析國家社會原理的禮治論。 ◎ 理解漢朝後中國國家體制的設計藍圖，必須從理解荀子禮治論開始。 本書以「禮治」與「綜合」為切入點，闡明《荀子》書中政治思想的淵源、構造以及特色，並對荀子的生平、其文本的流傳以及戰國時代「禮」概念的發展等問題，進行完整且系統性的說明。 作者將戰國時代的思想演變，分成以孔子至孟子的早期儒家與墨家思想為主要內容的「倫理論辯」階段，和以慎到、田駢等稷下學者與道家等戰國中、晚期思想為主要內容的「分析論述」階段，並主張荀子以「禮」概念綜合了此 兩種思想潮流。經由闡述「禮」概念的各種功能，荀子將當時備受懷疑的倫理工夫之效能，以及過度抽象化的各種政治論辯內容，重新界定為每個人都能夠實踐的倫理準則；早期儒墨的「倫理論辯」，由此提升為富有分析國家社 會原理的「禮治論」。而因為荀子的禮治論兼有豐富的倫理實踐意涵，以及分析國家社會的理論意涵，其後更成為漢朝建立國家制度與倫理基礎時的設計藍圖。 經由作者條分縷析地說明，讀者當能對荀子的禮治思想有更深入的了解，進而掌握其整體面貌。.

西元前256年，周赧王被秦昭襄王所征服。由此，戰國時代最後階段的華夏世界進入三十五年的「後周魯時代」。 本書提出：在此時期周天子不在的政治權威空白時期，實為《荀子》和《呂氏春秋》兩書之出現的主要契機。以這樣歷史背景為主要契機誕生的兩書，其政治哲學的目標便應該在於構想能治理全天下人民之國家的建立──《荀子 》探求未來以禮義治理天下的君王；《呂氏春秋》則向已成為「de facto天子」的秦王，為提升至名正言順的天子，提供政策綱要和實踐細則。 作者根據較為嚴謹的「觀念史／概念史」分析，闡述《荀》、《呂》兩書在思維上、概念上、論述內容上等多層次的思想特質及其歷史角色。期盼本書在戰國秦漢時代的歷史和思想相關議題之探討能夠提供較新的切入點，並擴大 研究視野。.

本書構畫「忠」概念在中國春秋戰國時代的演變，並嘗試藉此闡明其功能與特質。在春秋到戰國早期的政治思想中，「忠」和「忠信」概念對於國家社稷的生存幾乎是最高價值，而且到戰國中期更具有涵蓋「天下」的普遍性。然 而在戰國中期以後，道家與稷下思想家如慎到等人開始批判「忠」的價值，並且將原本以道德動機為主要內涵的「忠」概念、轉變成以個人利益為主要實踐動機的「忠」概念。面對此趨勢，戰國晚期的《荀子》和《呂氏春秋》都 試圖重新界定「忠」對國家運作的正面價值，而《韓非子》雖然基本上接受稷下學者之「反忠論」，但還是肯定「忠臣」是國家社稷安定的關鍵角色。本書也對中日韓及歐美學者過去研究「忠」概念的成果有詳細評述。.
