“The rulers of tomorrow's over-populated and over-organized world will try to impose social and cul­tural uniformity upon adults and their children. To achieve this end, they will (unless prevented) make use of all the mind-manipulating techniques at their disposal and will not hesitate to reinforce these methods of non-rational persuasion by economic coer­cion and threats of physical violence. If this kind of tyranny is to be avoided, we must begin without delay to educate ourselves and our children for freedom and self-government.”
