In the introduction to his Elements of Semiology (1964), Roland Barthes argues that for all the icons and images that surround us, we remain a civilization of the word:

“Semiology has so far concerned itself with codes of no more than slight interest, such as the Highway Code; the moment we go on to systems where the sociological significance is more than superficial, we are once more confronted with language. it is true that objects, images and patterns of behaviour can signify, and do so on a large scale, but never autonomously; every semiological system has its linguistic admixture. Where there is a visual substance, for example, the meaning is confirmed by being duplicated in a linguistic message (which happens in the case of the cinema, advertising, comic strips, press photography, etc.) so that at least a part of the iconic message is, in terms of structural relationship, either redundant or taken up by the linguistic system. As for collections of objects (clothes, food), they enjoy the status of systems only in so far as they pass through the relay of language, which extracts their signifiers (in the form of nomenclature) and names their signifieds (in the forms of usages or reasons): we are, much more than in former times, and despite the spread of pictorial illustration, a civilisation of the written word. Finally, and in more general terms, it appears increasingly more difficult to conceive a system of images and objects whose signifieds can exist independently of language: to perceive what a substance signifies is inevitably to fall back on the individuation of a language: there is no meaning which is not designated, and the world of signifieds is none other than that of language.”
