Television and books are both hot media, and there is not much room for the audience or readers to participate, which means that the space left for you to reorganize is compressed by the discourse patterns of these two media. When McLuhan studied TV, he regarded TV as a cool medium. Later the development of television proved that it was not cold at all. The distinction between cold media and hot media has always been controversial. The value of this concept lies in that it gives us a perspective to look at the media from the participation required by the media form itself. So cold/heat can only be used to make a relative distinction, and the difference between them lies in the so-called "clarity" of information. Cold media has low definition and high audience participation; The heating medium has a high definition and requires a low degree of intervention. In this sense, if we use the concept of cold/hot, books are cold media and TV programs are hot media. People who watch TV are passive, while people who read books are active. As an extension of human eyes and ears, the information it carries can easily enter your brain; For books, you don't take the initiative to identify them, and even simple sentences are meaningless garbled. When you sit in front of the TV festival, it occupies your sensory organs and keeps your sensory organs busy. People who are addicted to the so-called high-end talk shows generally have no real thinking ability, but only make people delude themselves into believing their feelings and ideas, which is a state of being free from facing up to and doing nothing. Television is dictatorial and books are democratic. Television always speaks for itself. They help you complete all the words. Even if you feel something after reading it, most of the time you are still following the path they suggested. If it is not sensational, what it conveys is basically what you see is what you get. The most dangerous thing is that it is still selling a dangerous way of thinking: self-evident values; Books are actually more convincing in content, but what they usually say is correct and needs to be accepted, so people are too lazy to resist. In my opinion, the greatest advantage of books is to show readers the creative logic of excellent authors in sorting out fragments.
