With the invention of the clock, Eternity ceased to serve as the measure and focus of human events. - Neil Postman

Television is our culture's principal mode of knowing about itself. Therefore — and this is the critical point — how television stages the world becomes the model for how the world is properly to be staged. It is not merely that on the television screen entertainment is the metaphor for all discourse. It is that off the screen the same metaphor prevails. (92)

In the Middle Ages, there was a scarcity of information but its very scarcity made it both important and usable. This began to change, as everyone knows, in the late 15th century when a goldsmith named Gutenberg, from Mainz, converted an old wine press into a printing machine, and in so doing, created what we now call an information explosion. ...Nothing could be more misleading than the idea that computer technology introduced the age of information. The printing press began that age, and we have not been free of it since.

A fifth kind of semantic awareness has to do with what might be called the "photographic" effects of language. We live in a universe of constant process. Everything is changing in the physical world around us. We ourselves, physically at least, are always changing. Out of the maelstrom of happenings we abstract certain bits to attend to. We snapshot these bits by naming them. Then we begin responding to the names as if they are the bits that we have named, thus obscuring the effects of change. The names we use tend to "fix" that which is named, particularly if the names also carry emotional connotations... There are some semanticists who have suggested that such phrases as "national defense" and "national sovereignty" have been... maintained beyond the date for which they were prescribed. What might have been politically therapeutic at one time may prove politically fatal at another.
