Voting, we might even say, is the next to last refuge of the politically impotent. The last refuge is, of course, giving your opinion to a pollster, who will get a version of it through a desiccated question, and then will submerge it in a Niagara of similar opinions, and convert them into--what else?--another piece of news. Thus we have here a great loop of impotence: The news elicits from you a variety of opinions about which you can do nothing except to offer them as more news, about which you can do nothing.

We can make the trains run on time but if they are not going where we want them to go, why bother?

Because he did not have time to read every new book in his field, the great Polish anthropologist Bronislaw Malinowski used a simple and efficient method of deciding which ones were worth his attention: Upon receiving a new book, he immediately checked the index to see if his name was cited, and how often. The more "Malinowski" the more compelling the book. No "Malinowski", and he doubted the subject of the book was anthropology at all.

If we may say that the Age of Andrew Jackson took political life out of the hands of aristocrats and turned it over to the masses, then we may say, with equal justification, that the Age of Television has taken politics away from the adult mind altogether.

Everything in our background has prepared us to know and resist a prison when the gates begin to close around us . . . But what if there are no cries of anguish to be heard? Who is prepared to take arms against a sea of amusements? To whom do we complain, and when, and in what tone of voice, when serious discourse dissolves into giggles? What is the antidote to a culture's being drained by laughter?

My argument is limited to saying that a major new medium changes the structure of discourse; it does so by encouraging certain uses of the intellect, by favoring certain definitions of intelligence and wisdom, and by demanding a certain kind of content - in a phrase, by creating new forms of truth-telling.

As a culture moves from orality to writing to printing to televising, its ideas of truth move with it.
