“We now experience simultaneously the dropout and the teach-in. The two forms are correlative. They belong together. The teach-in represents an attempt to shift education from instruction to discovery, from brainwashing students to brainwashing instructors. It is a big dramatic reversal. Vietnam, as the content of the teach-in, is a very small and perhaps misleading Red Herring. It really has little to do with the teach-in, as such, anymore than with the dropout.”

— Marshall McLuhan, “Address at Vision 65” , p. 11-12
