A brief analysis of the debate on the art def＇mition in contemporary aesthetic world
20世纪不断涌现的先锋艺术给艺术定义提出难题，形成了西方美学界文艺理论界旷日持久的争论，系统考察有关艺术定义的理论有其必要性。比较研究韦兹的“家族相似”理论、丹托的“艺术界”理论、迪基的体制理论，分析优缺点，在此基础上我们尝试用目的论的方法来探讨艺术定义问题。Emerging vanguard art in the 20th century has caused a difficult problem for the art definition, forming a protracted debate in the western aesthetic and literary theorists. Therefore, it is very necessary and urgent for the Chinese academics to systematically examine these theories. We make a comparative study of the new Wittgensteinism, Danto＇s ＂art world＂ theory, Dickie＇s institutional theory, and analyze its advantages and disadvantages. Based on these, we try erploring art definition by using a teleological approach.
