Sight, when used in the context of nature, creates direct communication with reality. It implies that one is involved in this particular reality and quickly leads a person to action. But when the image has become artificial and is purely a means of knowledge, the reaction persists. I feel directly involved in what I see, just as prehistoric people did. And if I am seeing objects or ideas, I am not truly independent; I cannot really take my distance from these objects. From the intellectual point of view, this means I cannot really exercise my critical faculties. The use of images to transmit knowledge leads to the progressive elimination of distance between a person and his knowledge, because of the way we are made to participate when this means is used (this is, of course, in perfect accord with technical civilization, and to be desired by its standards). The critical faculties and autonomy of the thinking person are also eliminated.
