Based on an empirical illustration of Onta pottery and more broadly a discussion of the Japanese Mingei movement, we study the intimacy between craft work, ethics and time. We conceptualize craft work through the temporal structure of tradition, to which we find three aspects: generational rhythms of making; cycles of use and re-use amongst consumers and a commitment to historically and naturally attuned communities. We argue these temporal structures of tradition in craftwork are animated by two contrasting but co-existing ideas (...) of the good: the moral and the ethical. By developing the work of Elizabeth Grosz, we conceptualize this distinction between moral and ethical as a temporal phenomenon, specifically in differing relations to ideas of the future. Moral aspects of craft work understand the future as a progression from past, whether in preserving practices and norms, or improving upon them in relation to ideals. Ethical aspects understand the future as inherently open to chance and divergence, valuing difference, accident and the possibilities for creativity these entail. Empirically, we show evidence of both aspects in the case of Mingei—a organized movement dedicated to preserving and promoting traditional Japanese craft work. We contribute to studies of craft work by revealing and classifying its temporal aspects. We contribute to studies in business ethics by conceptualising a generative distinction between morals and ethics configured through differing understandings of time. (shrink)

Under the presupposition that human time perception is distorted in intertemporal choice, this study constructs a time scale in the framework of axiomatic measurement. First, the conditions (homogeneity of degree one or two) to identify the form of a time scale are proposed so that one can determine whether the hyperbolic or exponential is a more suitable function for modeling people’s discounting. Homogeneity of degree one implies that subjective time delay is measured by a power scale and its discount function (...) becomes a power-exponential type, whereas homogeneity of degree two implies that subjective time delay is measured by a log scale and its discount function becomes a hyperbolic type. Second, a method is shown for constructing a model that can reflect subadditive and superadditive discounting. A non-commutative and non-associative concatenation operation is provided to generate a time string consisting of subdivided durations that incorporates the effect of repeated delay with a subdivided duration. The discounting model is yielded by substituting these strings in an exponential model equipped with a generalized time scale, and the determination of subadditivity or superadditivity depends on whether the discount function value of a product by the non-commutative and non-associative operation is, respectively, smaller or greater than that of a product by an operation of the usual extensive structure.

After touching on the three most common misconceptions regarding boomerangs, the author goes on to explain why a boomerang is crescent shaped.The author explains, using the principle of precession motion, why a boomerang turns leftward and why it falls sideways; and he performs a comprehensive analysis through the “right-hand rule,” using the example of a gyro top.The author also explains how to make and fly the boomerang he invented—one that can fly inside a room and come back correctly.

哲学というととかく難しく分かりにくいように思われがちだが、哲学者にはまずはじめにイメージがあり、術語による概念化はそのあとのことだと著者は言う。さまざまな哲学者が差し出した寓意や比喩を蒐集し、それらを もとにイメージの系譜学とでもいうべきものを作ろうとしたのが本書である。プラトンからヘーゲルまでの哲学の歴史を徹底的に噛み砕き、しかも原典に忠実に解説している。この以上分かりやすい哲学史の概説書は他にな い。.

It is shown that there is a Kripke incomplete logic in NExt(KTB ⊕ □2 p → □3 p). Furthermore, it is also shown that there exists a continuum of Kripke incomplete logics in NExt(KTB ⊕ □5 p → □6 p).

In this paper, we present three main results on orthologics. Firstly, we give a sufficient condition for an orthologic to have variable separation property and show that the orthomodular logic has this property. Secondly, we show that the class of modular orthologics has an infinite descending chain. Finally we show that there exists a continuum of orthologics.

Japanese prefer odd numbers, whereas Westerners emphasize even numbers, an observation that is clear from the distribution of number-related words in Japanese and English dictionaries. In this article, the author explains why these two cultures differ by surveying the history of numbers, including yin-yang thought from ancient China, ancient Greek philosophy, and modern European mathematics. The author also mentions that oddness and evenness are only mathematical concepts, but understanding the cultures and histories of individual countries contributes to world peace.

The self-organizing consciousness (SOC) is not sufficient to account for young children's ability to acquire complex rules and word-object mappings. First, the attention-association cycles suggested by the SOC are unlikely to happen because recurrence of particular stimulus properties usually disengages the attention of an observer. Second, “primitive processors” preinstalled in the system make the SOC unnecessarily complex.

This article develops an axiom system to justify an additive representation for a preference relation ${\succsim}$ on the product ${\prod_{i=1}^{n}A_{i}}$ of extensive structures. The axiom system is basically similar to the n-component (n ≥ 3) additive conjoint structure, but the independence axiom is weakened in the system. That is, the axiom exclusively requires the independence of the order for each of single factors from fixed levels of the other factors. The introduction of a concatenation operation on each factor A i (...) makes it possible to yield a special type of restricted solvability, i.e., additive solvability and the usual cancellation on ${\prod_{i=1}^{n}A_{i}}$ . In addition, the assumption of continuity and completeness for A i implies a stronger type of solvability on A i . The additive solvability, cancellation, and stronger solvability axioms allow the weakened independence to be effective enough in constructing the additive representation. (shrink)

We present here a Kripke-style semantics for propositional orthomodular logics that is based on the representation theorem for orthomodular lattices by D.J. Foulis , in which a sort of semigroups is employed. This semantics can characterize the logics above the orthomodular logic by some elementary conditions.
