Television screens saturated with commercials promote the utopian and childish idea that all problems have fast, simple, and technological solutions. You must banish from your mind the naive but commonplace notion that commercials are about products. They are about products in the same sense that the story of Jonah is about the anatomy of whales.

Children enter school as question marks and leave as periods.

Embedded in every technology there is a powerful idea, sometimes two or three powerful ideas. Like language itself, a technology predisposes us to favor and value certain perspectives and accomplishments and to subordinate others. Every technology has a philosophy, which is given expression in how the technology makes people use their minds, in how it codifies the world, in which of our senses it amplifies, in which of our emotional and intellectual tendencies it disregards.

What could be more metaphysically puzzling than addressing an unseen audience, as every writer of books must do? And correcting oneself because one knows that an unknown reader will disapprove or misunderstand?
