本文从柏拉图的摹仿理论出发,论述了柏拉图式图文观所决定的图文关系的主要特征,同时指出这一原则目前正受到以索绪尔为首的近代符号学学者的挑战。历史变迁的总趋势是:图像与文字各自的符号价值,从被遮蔽逐渐走向被彰显;图与文的关系,从必然一致走向可能龃龉。 Based on Plato ’s theory of imitation, this paper discusses the main features of the graphic - text relations determined by Platonic viewpoints, and points out that this principle is now challenged by modern semiotic scholars headed by Saussure. The general trend of historical change is that the respective symbolic values ​​of images and texts have been gradually revealed from being obscured. The relationship between the figure and the text can change from a certain unity to a possible one.
