"Until writing was invented, man lived in acoustic space: boundless, directionless, horizonless, in the dark of the mind, in the world of emotion, by primordial intuition, by terror. Speech is a social chart of this bog.
The goose quill put an end to talk. It abolished mystery; it gave architecture and towns; it brought roads and armies, bureaucracy. It was the basic metaphor with which the cycle of civilization began, the step from the dark into the light of the mind. The hand that filled the parchment page built a city."
(Marshall McLuhan, The Medium is the Massage. p. 48)
"Whence did the wond'rous mystic art arise,
Of painting SPEECH, and speaking to the eyes?
That we by tracing magic lines are taught,
How to embody, and to colour THOUGHT?"
