Abstract:Miki Kiyoshi's Philosophical Anthropology was written probably between 1933 and 1937, shortly after Philosophy of History (1931–1932) and prior to Philosophy of Technology (1942). Resonating with these major texts, this unfinished work represents Miki's interest in Kantian Anthropologie as well as his own views of the human. This study examines singularity, contingency, and poiesis as key ideas for understanding Miki's anthropology. Singularity of an event is defined by the binary of the present ex ante facto (before-the-fact) and ex post facto (...) (after-the-fact). Contingency of an event is defined by not having a sufficient ground within itself. An important thesis of Miki's anthropology is that an action is an event, singular and contingent by these definitions; it is poiesis (not praxis) irreducible to one's historical agency. This idea of singularity, with the self-contradictory binary of action-intuition ex ante facto and ex post facto, has ethical significance for debates on human cloning and global crisis today.

In this paper, I discuss the problems of ``order in social situations'' using a computer simulation of iterated N -person prisoners' dilemma game. It has been claimed that, in the case of the 2 -person prisoners' dilemma, repetition of games and the reciprocal use of the ``tit-for-tat'' strategy promote the possibility of cooperation. However, in cases of N -person prisoners' dilemma where N is greater than 2, the logic does not work effectively. The most essential problem is so called ``sanctioning (...) problems''. In this paper, firstly, I discuss the ``sanctioning problems'' which were introduced by Axelrod and Keohane in 1986. Based on the model formalized by Axelrod, I propose a new model, in which I added a mechanism of players' payoff changes in the Axelrod's model. I call this mechanism norm-internalization and call our model `` norm-internalization game ''. Second, by using the model, I investigated the relationship between agents' norm-internalization (payoff-alternation) and the possibilities of cooperation. The results of computer simulation indicated that unequal distribution of cooperating norm and uniform distribution of sanctioning norm are more effective in establishing cooperation. I discuss the mathematical features and the implications of the results on social science. (shrink)

It is well known that the self-energy of the gauge bosons is quadratically divergent in the Standard Model when a simple cutoff is imposed. We demonstrate phenomenologically that the quadratic divergences in fact unify. The unification occurs at a surprisingly low scale, \(\Lambda _\mathrm {u}\approx 4\times 10^7\) GeV. Suppose now that there is a spontaneously broken rotational symmetry between the space-time coordinates and gauge theoretical phases. The symmetry-breaking pattern is such that the gauge bosons arise as the massless Goldstone bosons, (...) whereas the dilatonic mode acts as the massive (Higgs) boson, whose vacuum expectation value determines the gauge couplings. In this case, the quadratic divergences or the tadpoles of the gauge boson self-energy should indeed unify because these divergences need to be cancelled by a universal dilatonic contribution, assuming dynamical symmetry breaking. If there is dynamical symmetry breaking, we are in principle able to calculate the value of the gauge couplings as well as the scale hierarchy \(\Lambda _\mathrm {cut}/\Lambda _\mathrm {u}\) . We perform this calculation by adopting a naive quartic symmetry-breaking potential which unfortunately violates local gauge invariance. Using tadpole-cancellation and dilatonic self-energy conditions, the value of \(\Lambda _\mathrm {cut}\) is then found to be approximately \(4\times 10^{18}\) GeV in the Feynman gauge and \(5\times 10^{15}\) GeV in the Landau gauge. The cancellation of an anomaly in the dilaton self-energy requires that the number of fermionic generations equals three. The symmetry-breaking needs to be driven by some other mass-generating mechanism such as electroweak symmetry breaking. Our estimation for \(\Lambda _\mathrm {u}\) is of the correct order if \(\Lambda _\mathrm {cut}\approx 5\times 10^{15}\) GeV. (shrink)
