Fuzzy logic has become an important tool for a number of different applications ranging from the control of engineering systems to artificial intelligence. In this concise introduction, the author presents a succinct guide to the basic ideas of fuzzy logic, fuzzy sets, fuzzy relations, and fuzzy reasoning, and shows how they may be applied. The book culminates in a chapter which describes fuzzy logic control: the design of intelligent control systems using fuzzy if-then rules which make use of human knowledge (...) and experience to behave in a manner similar to a human controller. Throughout, the level of mathematical knowledge required is kept basic and the concepts are illustrated with numerous diagrams to aid in comprehension. As a result, all those curious to know more about fuzzy concepts and their real-world application will find this a good place to start. (shrink)

How is it possible to say that truth can be of one kind at the conventional level and totally different in the ultimate plane? As Matilal ( 1971 , p. 154) points out, Kumārila (ca. 600–650), a Mīmāṃsaka philosopher, claims that the Buddhist doctrine of two truths is “a kind of philosophical ‘double-talk’.” It is Prajñākaragupta (ca. 750–810), a Buddhist logician, who tries to give a direct answer to this question posed by Kumārila from the Buddhist side. He argues that (...) even a Mīmāṃsaka cannot demonstrate the validity ( prāmāṇya ) of the Veda without accepting two truth levels. His point is this. Consider the proposition to be proved: the Veda is valid. If the Veda is already known as valid, then it is useless to prove this proposition. But if it is already known as invalid, then it is impossible to prove this proposition. Therefore in the argument to prove the proposition, the Veda is not to be regarded either as valid or as invalid. This means that at the first stage of the argument one has the concept of the Veda as neutral in validity. However, as soon as one acquires the knowledge of the Veda as valid through the argument, one has to repudiate such a conception of the Veda. The acceptance of the Veda as neutral in validity is to the acceptance of the Veda as valid as the conventional truth is to the ultimate truth. (shrink)

It has been suggested that preparing to teach and teaching are conditionally effective in enhancing one’s own learning. This paper focuses on interactivity—the level of teacher-student interaction in expected or actual teaching—as the potential key to understanding and controlling the variability in the effectiveness of learning by preparing to teach and teaching. By summarizing and reanalyzing the results of previous studies, I suggest that the learning benefits of studying with the expectation of direct teaching (i.e., teaching a student face-to-face) are (...) greater than those of studying with the expectation of indirect teaching (i.e., teaching a student indirectly by creating a lecture video, providing written explanations, or using other means) and that learning by direct teaching surpasses learning by explaining to oneself or indirect teaching at least after preparing to do so. Next, three candidate explanations for the impact of interactivity are discussed: the advantages of asking and answering questions, obtaining additional information about and from one’s student, and enhancing one’s motivation to process learning material deeply while preparing to teach and teaching. Finally, I conclude with the remaining questions and directions for future research. (shrink)

The Christian philosopher Muto Kazuo contributed substantially to the predominantly Buddhist “Kyoto School of Philosophy.” Through critical exchange with its representatives, he opened up new perceptions of Christian faith, enabled mutual understanding between Buddhism and Christianity, and challenged the Western dialectical method.

「主体」はもちろんsubjectの翻訳語である。明治以降、この語がわが国に入ってくると、「主観」「主体」「主語」などさまざまな翻訳語があらわれる。たとえば西田幾多郎は、初期は「主観」をつかっているが、 後期になると「主体」しか出てこなくなる。この移行ははたして何を意味するのだろうか。戦後には、「主体性論争」がわき起こり、たとえば学生運動では「主体性」という言葉がキーワードとなった。明治期の受容から、 戦後、そして現代に至るまで、それぞれの時代の趨勢となった思想に伏流する「主体」を追い続け、日本近代思想史にあらたな視座を提供する、知的興奮にあふれた一冊。.
