"The dream of absolute free speech is a myth and a delusion. No society has ever granted it. We do not recognize the right of a man to shout "fire!" in a crowded theater, nor to call for the execution of the President, nor to publish totally false and malicious statements with respect lo a man. Speech must be responsible to be free, and there is a social necessity for freedom of responsible speech. The advocates of free speech are logical in also demanding free action, freedom from all responsibility in speech and act. No society can exist if such total freedom from responsibility is permitted. Not surprisingly, the most vocal champions of free speech today are those who champion a revolution which will deny free speech to all others tomorrow. They suppress free speech in a very real fear of the responsible word as well as the irresponsible one. The foundations of their fear of contrary words is in part political safely, and in part religious fear."
