Introduce the alphabet to a culture and you change its cognitive habits, its social relations, its notions of community, history and religion. Introduce the printing press with movable type, and you do the same. Introduce speed-of-light transmission of images and you make a cultural revolution. Without a vote. Without polemics. Without guerrilla resistance. Here is ideology, pure if not serene. Here is ideology without words, and all the more powerful for their absence. All that is required to make it stick is a population that devoutly believes in the inevitability of progress. And in this sense, all Americans are Marxists, for we believe nothing if not that history is moving us toward some preordained paradise and that technology is the force behind that movement.

All that has happened is that the public has adjusted to incoherence and been amused into indifference.

As Thoreau implied, telegraphy made relevance irrelevant.
