Noam Chomsky on Debate

“The smart way to keep people passive and obedient is to strictly limit the spectrum of acceptable opinion, but allow very lively debate within that spectrum—even encourage the more critical and dissident views. That gives people the sense that there's free thinking going on, while all the time the presuppositions of the system are being reinforced by the limits put on the range of the debate.”

“[In] democratic societies … the state can't control behavior by force. It can to some extent, but it's much more limited in its capacity to control by force. Therefore, it has to control what you think. … One of the ways you control what people think is by creating the illusion that there's a debate going on, but making sure that that debate stays within very narrow margins. Namely, you have to make sure that both sides in the debate accept certain assumptions, and those assumptions turn out to be the propaganda system. As long as everyone accepts the propaganda system, then you can have a debate.”
