In the knowledge system of human civilization, language is our main tool of intelligent source and communication, while image is in the awkward condition of shifting and hesitation, and in the incessant attack and elimination due to social ideologies, for example, iconoclasm is a kind of negative oppression and eradication of worldly religious images, which aims not at hoping image becomes the worldly stuff that might affect the divine belief and refuses image is the symbol of divine supremacy.

在人类文明的知识体系中，语言是我们主要的知识来源和交流工具，而图像则处于漂移、犹豫的尴尬处境，不断因为社会意识形态需要而成为被攻击、被消灭的对象，如偶像破坏运动就是对世俗宗教图像的一次否定性压制和根除，目的是不希望图像成为影响神性信仰的世俗物品，拒绝图像是神性至上的象征。
