Knowledge is Power for the People, Ignorance is Power for the Rulers. If you don't know the nature or origin of the ingredients in the food you buy, it's easier to sway your purchasing decisions through advertising. If you don't know that your priest keeps being moved around due to accusations of child molestation, it's easier to get you to entrust your children to his tender, loving care. If you don't know what the government is doing as part of its global war on terrorism, it's easier to get you to believe it's all for your own good. If you don't know that there are others out there whose sexual preferences aren't quite what religious and social leaders say God demands, it's easier to repress your own feelings and pretend to be like "everyone else."
