     View Summary

    The purpose of our research is to construct a new philosophical foundation of ‘global legisprudence’ by developing and integrating the theoretical resources of legisprudence and global justice. We revealed that the conventional theories of legisprudence which almost exclusively focused on domestic legislation could not appropriately deal with the problems that domestic legislation and global order formation interacted with each other. Then we presented some guides for division of labor between domestic legislation and global law-making, and explored how to guarantee democratic accountability of both. Thereby we built a philosophical foundation of global legisprudence.

  • 契約法理論から見た成人同士の共同生活と家事労働負担

    2023  

     View Summary

    本研究の目的は、マーサ・ファインマンの、婚姻ないし成人間の共同生活の契約法化というアイディアを検討することにある。このアイディアに対しては、経済力やジェンダーをめぐる交渉力格差が個々の共同生活実践や契約に反映されてしまうおそれに対して無頓着だという批判がなされてきた。そこで本研究は、クレア・チェンバーズの「婚姻なき国家」の構想を批判的に検討するために、契約法理論の文献を読み、いくつかの研究成果をあげた。

  • <自由な行為の帰結に対して責任をとること>と家族責務の引き受けに関する法哲学的検討

    2022  

     View Summary

    自身が自由に行った行為の結果に責任を取ることは、リベラリズムの重要な原理である。本研究では、この原理を「家族」に適用するどういうことかについて考えた。特に、他者と共同生活を送る過程で自分が経済的に脆弱になったこと、自ら行ったことの結果として子どもが生み出されたことへの責任について検討した。研究費は、雑費(研究会参加費用、学会参加費用)、消耗品費(文房具等)、旅費(岡山)、図書資料費に使用した。研究成果は、書籍内論文1点、雑誌論文1点、書評論文1点、学会発表1点、研究会発表1点という形で公表された。

  • 家族における自由とその限界――婚姻法の契約法化とケアの制度をめぐる最も正義に適う構想はどれか?
