Well, one of the points of the book is that you really can't summarize complex information. And that television is a medium of summary or reductionism - it reduces everything to slogans. And that's one criticism of it, that it requires everything to be packaged and reduced and announced in a slogan-type form.
But let me say this: the book is not really four arguments, it's really hundreds of arguments broken down into four categories. And the categories have to do with a variety of effects that are not normally discussed. Most criticisms of television have to do with the television program content. People say if there is less violence on television or less sexism on television, or less this or less that, television would be better. If there were more programs about this or more programs about that, then we'd have "good television".
My own feeling is that that is true - that it's very important to improve the program content - but that television has effects, very important effects, aside from the content, and they may be more important. They organize society in a certain way. They give power to a very small number of people to speak into the brains of everyone else in the system night after night after night with images that make people turn out in a certain kind of way. It affects the psychology of people who watch. It increases the passivity of people who watch. It changes family relationships. It changes understandings of nature. It flattens perception so that information, which you need a fair amount of complexity to understand it as you would get from reading, this information is flattened down to a very reduced form on television. And the medium has inherent qualities which cause it to be that way.
And the book is really about television considered from a holistic point of view, from a biological point of view - perceptual, environmental, political, social, experiential, as well as the concrete problems of whether a program is silly or not. But other people deal with that very well. My job was to talk about television from many of these other dimensions which are not usually discussed.
