Ask yourself why totalitarian dictatorships find it necessary to pour money and effort into propaganda for their own helpless, chained, gagged slaves, who have no means of protest or defense.

For centuries, the battle of morality was fought between those who claimed that your life belongs to God and those who claimed that it belongs to your neighbors - between those who preached that the good is self-sacrifice for the sake of ghosts in heaven and those who preached that the good is self-sacrifice for the sake of incompetents on earth. And no one came to say that your life belongs to you and that the good is to live it.
