现代美学的一个重要事件是“存在论美学”对古典“本体论美学”的挑战。虽然作为一种文化思潮的存在主义曾因其所产生过的巨大社会影响而引人注目 ,但对其所蕴含的丰富而宝贵的美学资源的重视迄今仍很不够。本文试图从柏格森的“生命绵延”说、胡塞尔的“生活世界”说和海德格尔“生存筹措”说入手 ,对这一思想的美学特色与贡献作出某种总结。 An Important Event of Modern Aesthetics is the Challenge of “Ontological Aesthetics” to Classical “Ontology Aesthetics.” Although existentialism as a cultural trend attracted attention due to the enormous social impact it produced, its emphasis on the rich and valuable aesthetics resources it contains is still not enough so far. This article attempts to make some sorts of conclusions about Bergensen’s “life span” theory, Husserl’s “life world” theory and Heidegger’s “survival financing theory”.
