    　View Summary

    Although Bertrand Russell is now widely recognized as a founder of modern mathematical logic, his work on logic suggests that he himself had a totally different conception of logic from that of modern mathematical logic. Many commentators have tried to give an account of this difference by explaining logic for him as a universal language, a formal language that captures ʻthe logical furniture of the universeʼ. This explanation, however, turns out to be misleading, when we focus upon his view of language as a ʻtransparent medium.ʼ It seems to be more correct to think that Russell conceived of logic as concerned with the logical furniture of the world, or more precisely, with the forms that govern the way the world is, while he took a formal language merely as a medium to describe these forms. I will call such a view of logic ʻthe metaphysical conception of logic.ʼ The aim of this paper is to show that, by attributing this conception of logic to Russell, we can reach a better understanding of the difference between logic as Russell conceived it and modern mathematical logic. To illustrate his metaphysical conception of logic I will focus upon two features of Russellʼs philosophy, which in turn suggest that he shared the metaphysical conception of logic with his predecessors. Although I cannot develop this point fully,this would be another advantage of the above account of Russellʼs logic.

  • 初期分析哲学史における「構成」概念の探究

    2021  

    　View Summary

    本特定研究課題は、分析哲学、すなわち、現代の英語圏を中心とする哲学の営みの出発点の一つともなった「外部世界 external world」の実在性をめぐる論争の内実を文献学的な探求を通じて整理することで、分析哲学の創始者の一人であるバートランド・ラッセルが提示した外部世界の「論理的構成 logical construction」という考えに対するより正確な理解を得るものである。　この課題への取り組みの成果は、国内外の学会にて、査読付き発表（Society for the Study of the History of Analytical Philosophy, 7月, Vienna/online）と招待講演（日本ホワイトヘッド・プロセス学会10月、オンライン）という形で公表されている。
