A Study on the Relations between the Concepts of Reason in the Western Philosophy and Scientific Rationality

本研究的目的是澄清科学合理性的意义和限度，这是说，在这些天已经失去了公众的信任。通过考察西方哲学中从古代到近代的现代科学和科学理性的起源和本质，来探求西方哲学中理性概念与科学理性的关系，试图从一开始就对西方哲学各个时期的理性和理性概念有一个清晰的把握。除此之外，我们还考虑了现代科学理性在这些日子里应该如何呈现。小林教授从数学、自然科学（特别是物理学）和人文科学（社会科学）的角度，探讨了科学理性的特征和局限性。汉达教授批评了马克斯·舍勒对“技术智能”的批评。Shiode教授比较了爱奥尼亚自然哲学家和巴门尼德的理性主义世界观。仲井教授对大卫休姆斯在《人性论》中的“关于理性的怀疑论”提出了质疑。米诺教授批评了托马斯内格尔关于“道德运气”的论文。川藏教授比较了中世纪神学家理解哲学本质的两种合理性。在一个早产儿的生物伦理案例中，土屋教授讨论了合理性在证明两种不相容的伦理判断中的作用。

The aim of this study was to clarify both the significance and the limit of scientific rationality, which is said to have lost reliance from the public in these days. We have searched the relations between the concepts of reason in the western philosophy and scientific rationality, by investigating the origin and the essence of the modern science and scientific rationality in the western philosophy from the ancient to the modern times.From the beginning of this study we have tried to grasp clearly the concepts of reason and rationality in each times of the western philosophy. In addition to do that, we considered how modern scientific rationality should be presented in these days. The papers written for the report of this project are the fruits of these considerations.Prof.KOBAYASHI discusses the characteristics and the limitations of scientific rationality in the context of mathematics, natural sciences (especially physics), and human sciences (social sciences). Prof.HANDA criticizes Max Scheler's criticism of "technological intelligence." Prof.SHIODE compares rationalistic world views of the Ionian natural philosophers and of Parmenides. Prof.NAKASAI inquires in David Humes "Of scepticism with regard to reason" in A Treatise of Human Nature. Prof.MINO criticizes Thomas Nagel's thesis on "moral luck." Prof.KAWAZOE compares two kinds of rationality appeared in the medieval theologians' ways of understanding the essence of philosophy.
