“Thus with the invention of writing, human beings took one step further back from the world. Texts do not signify the world; they signify the images they tear up. Hence, to decode texts means to discover the images signified by them. The intention of texts is to explain images, while that of concepts is to make ideas comprehensible. In this way, texts are a metacode of images.”
