"Our constitution relies on our ... freedom to nourish independent and responsible intelligence and preserve our democracy from that submissiveness, timidity and herd-mindedness of the masses... The priceless heritage of our society is the ... right of each member to think as he will. Thought control is a copyright of totalitarianism, and we have no claim to it. It is not the function of our Government to keep the citizen from falling into error; it is the function of the citizen to keep the Government from falling into error. Robert Jackson, US Supreme Court, 1954
