Postman covers a key problem of our current society right up front in the first paragraph:
"Today, we must look to the city of Las Vegas, Nevada, as a metaphor of our national character and aspiration, its symbol a thirty-foot-high cardboard picture of a slot machine and a chorus girl. For Las Vegas is a city entirely devoted to the idea of entertainment, and as such proclaims the spirit of a culture in which all public discourse increasingly takes the form of entertainment. Our politics, religion, news, athletics, education and commerce have been transformed into congenial adjuncts of show business, largely without protest or even much popular notice. The result is that we are a people on the verge of amusing ourselves to death."
The following rather long quote gives a good summary of our specific danger -- a bias that we don't even have a clue to our peril:
"I met McLuhan thirty years ago when I was a graduate student and he an unknown English professor. I believed then, as I believe now, that he spoke in the tradition of Orwell and Huxley—that is, as a prophesier, and I have remained steadfast to his teaching that the clearest way to see through a culture is to attend to its tools for conversation. I might add that my interest in this point of view was first stirred by a prophet far more formidable than McLuhan, more ancient than Plato.
In studying the Bible as a young man, I found intimations of the idea that forms of media favor particular kinds of content and therefore are capable of taking command of a culture. I refer specifically to the Decalogue, the Second Commandment of which prohibits the Israelites from making concrete images of anything. “Thou shalt not make unto thee any graven image, any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water beneath the earth.” I wondered then, as so many others have, as to why the God of these people would have included instructions on how they were to symbolize, or not symbolize, their experience. It is a strange injunction to include as part of an ethical system unless its author assumed a connection between forms of human communication and the quality of a culture.
We may hazard a guess that a people who are being asked to embrace an abstract, universal deity would be rendered unfit to do so by the habit of drawing pictures or making statues or depicting their ideas in any concrete, iconographic forms. The God of the Jews was to exist in the Word and through the Word, an unprecedented conception requiring the highest order of abstract thinking. Iconography thus became blasphemy so that a new kind of God could enter a culture."
In this day of Twitter, Facebook, 24x7 "news", etc, we are no longer on the "verge" -- the culture that Postman feared losing is long gone.
To wit, this quote:
"Because the television commercial is the single most voluminous form of public communication in our society, it was inevitable that Americans would accommodate themselves to the philosophy of television commercials. By “accommodate,” I mean that we accept them as a normal and plausible form of discourse. By “philosophy,” I mean that the television commercial has embedded in it certain assumptions about the nature of communication that run counter to those of other media, especially the printed word.
For one thing, the commercial insists on an unprecedented brevity of expression. One may even say, instancy. A sixty-second commercial is prolix; thirty seconds is longer than most; fifteen to twenty seconds is about average. This is a brash and startling structure for communication since, as I remarked earlier, the commercial always addresses itself to the psychological needs of the viewer. Thus it is not merely therapy. It is instant therapy. Indeed, it puts forward a psychological theory of unique axioms: The commercial asks us to believe that all problems are solvable, that they are solvable fast, and that they are solvable fast through the interventions of technology, techniques and chemistry."Would our current model for brevity be a Tweet?
Again, our technologies have instilled a bias that any problem is quickly, easily, painlessly, and without detrimental side effects "solvable" -- which is a lie, as our alarming suicide, depression, addiction, loneliness and general "brokenness" makes clear.
Our desire however is for more of the same quick, easy, obvious, etc "solutions" -- 100% guaranteed in the real world vs the media / entertainment world, to deepen our tragedy.
