由日本電影大師黑澤明執導的作品《生之慾》乃是描述公務員渡邊‧堪治的一生，是黑澤明一九五二年改編自托爾斯泰中篇小說《依凡．依里奇之死》的電影名作。此部作品探討人生存在的意義，主角渡邊‧堪治在得知自己患了不治之症後，對自己人生的反省與對生命真實意義的探求，構成本部作品的核心。本論文運用馬丁‧海德格在《存在與時間》一書中對本真性的探討，試論主角的精神由死亡到覺醒，進而貫徹自己的信念的整個過程。

Co-written and directed by Akira Kurosawa, Ikiru is a 1952 Japanese film inspired by Lev Tolstoy’s “The Death of Ivan Illyich”. In this film, Kurosawa presents the life of a middle-aged petty official Kanji Watanabe, who, after learning of his mortal illness, starts to examine his own past and, seeing its meaninglessness, tries to find a way to endow his remaining life with meaning, with what Martin Heidegger calls “authenticity”. The purpose of this paper is to interpret Ikiru in terms of Heidegger’s concept of authenticity as explicated in his book Being and Time.
