The literate man is a sucker for propaganda...You cannot propagandize a native. You can sell him rum and trinkets, but you cannot sell him ideas.
Marshall McLuhanUntil writing was invented, man lived in acoustic space: boundless, directionless, horizonless, in the dark of the mind, in the world of emotion.
Marshall McLuhanNew media may at first appear as mere codes of transmission for older achievement and established patterns of thought. But nobody could make the mistake of supposing that phonetic writing merely made it possible for the Greeks to set down in visual order what they had though and known before writing. In the same way printing made literature possible. It did not merely encode literature.
