Numbness

The changes from one technology (one extension of our nervous system) to another create such intense experiences that we adopt a numbness in self defense.  Sometimes McLuhan associates this numbness specifically with hot media: At other times he applies this idea to any drastic change of media. And although he thinks that this numbness protects us, he is also contemptuous of it. This contempt may be motivated at least partly by McLuhan's belief that if we can stand aside from our numbness we can gain control.
