Perfection of the means of communication has meant instantaneity. Such an instantaneous network of communication is the body-mind unity of each of us. When a city or a society achieves a diversity and equilibrium of awareness analogous to the body-mind network, it has what we tend to regard as a high culture. But the instantaneity of communication makes free speech and thought difficult if not impossible, and for many reasons. Radio extends the range of the casual speaking voice, but it forbids that many should speak. And when what is said has such range of control, it is forbidden to speak any but the most acceptable words and notions. Power and control are in all cases paid for by loss of freedom and flexibility. (‘Culture Without Literacy’, Explorations 1, 1953)
