Since most subjects studied in school consist largely of theories... language education must include not only the serious study of what truth and fal… - Neil Postman

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.

[It] is not that television is entertaining but that it has made entertainment itself the natural format for the representation of all experience. […] The problem is not that television presents us with entertaining subject matter but that all subject matter is presented as entertaining. (87)

As the spectacular triumphs of technology mounted, something else was happening: old sources of belief came under siege. Nietzsche announced that God was dead. Darwin didn’t go as far but did make it clear that, if we were children of God, we had come to be so through a much longer and less dignified route than we had imagined, and that in the process we had picked up some strange and unseemly relatives. Marx argued that history had its own agenda and was taking us where it must, irrespective of our wishes. Freud taught that we had no understanding of our deepest needs and could not trust our traditional ways of reasoning to uncover them. John Watson, the founder of behaviorism, showed that free will was an illusion and that our behavior, in the end, was not unlike that of pigeons. And Einstein and his colleagues told us that there were no absolute means of judging anything in any case, that everything was relative. The thrust of a century of scholarship had the effect of making us lose confidence in our belief systems and therefore in ourselves. Amid the conceptual debris, there remained one sure thing to believe in — technology.
