後現代思潮下，何者是其隱而不宣的言說系統，後現代又為當代藝術開闢了怎樣的新視野。「後現代」在此涉及的是一種看法和態度，大都現身在價值、禁忌系統內，如Foucault所言，是某種不言自明的認識方法，這種認識法之所以有權力，在於這樣的論述被大眾接受；關於「神話」一詞，本文用以意指某種塑造的「事實」，此即Barthes 所指的被包裝成「自然法則」的常識。本文以「食飽未？」2007 亞洲藝術雙年展作品為主要論述對象，藉由此展來談「後現代」、「亞洲」與「藝術」觀念間的辯證關係，以及隱身其中的堅持反界定力道。

Under the influence of Postmodern thinking style, what is its tacit speech system or what a new vision postmodernism has created for modern arts? “Postmodernism” is involved in a perception and attitude which mostly exist within the value and taboo system. As Foucault stated,
it is a self-evident way of understanding, which is powerful because it is accepted by the public. With regards to the term “myth”, this paper refers it to a certain type of molded “truth”, which is the common sense being presented as “Natural Law” mentioned by Barthes. This paper focuses on “Have You Eaten Yet? 2007 Asian Art Biennial” as its main discussion object. It discusses the dialectical relationship between the concepts of “postmodernism”, “Asia” and “art” and analyzes
“anti-definition” that hides in these concepts which is not easily replaceable and highly distrusted.
