Moral Roots: Lib Con

This diverse talk by Jonathan Haidt explores the evolutionary benefits of morality and compares liberal moral roots of harm and fairness with conservative ones of harm, fairness, purity, in-group loyalty and authority. I think his insight is an argument for creating a democratic system that enhances the quality of debate in order to achieve moral diversity and counter group think. Interactive Democracy could do this.
"If you want the truth to stand clear before you, never be for or against. The struggle between 'for' and 'against' is the mind's worst disease."
