Here the connection with literacy and static visual experience as opposed to the dynamism of hearing seems obvious. But in fact, the connection is more subtle and more profound, since, as we have seen, although vision can be understood statically, whereas hearing cannot, visual experience is by no means always static.
There is much dynamism and change in our everyday visual experience. Our tendency to automatically think of vision as static is itself partly a product of taking the written or printed word, locked as it is into a semipermanent place in space, as the paradigm of something seen.
Thus, literacy not only superordinates visual experience and links it to verbalization but actually superordinates a particular moment of visual experience.
