What is the author of trouble with television trying to persuade people do?

In his book "The Trouble with Television," Neil Postman argues that television is a destructive force in society. He believes that television's constant stream of images and information is harmful to our ability to think critically and reason effectively. He also argues that television encourages passivity and discourages active participation in society.

Postman's goal in writing this book is to persuade people to be more critical of television and to limit their exposure to it. He wants people to realize that television is not just a source of entertainment, but that it also has a significant impact on our thoughts and behavior. He ultimately hopes that people will become more mindful of the effects of television and make changes in their viewing habits accordingly.
