Jonathan Haidt 1: The moral roots of liberals and conservatives (script)
Summary
Our society has two parties that are liberals and conservatives but they say to each other that other party is wrong and they are right.
However, in the world, the parties should cooperate to understand each other and to solve problems.
We are born with the same morality.
According to the study of the speaker, people have two common morality that is harm/care and fairness/reciprocity.
People hope to bond with others, care for others, feel compassion for others who are especially  weak or abused. They hope to be fair to each other.
However, there is pleasure in our world, things change, and people become selfish.
The parties start to pursue only their own benefit. Purity is lost,  making group is rejected from another group by authority.
Morality should be used not to battle between good and evil and not being against anything.
This story is not about only party but it leads to all our life. We have to think about moral authority from moral humility.
The better way is not to change other people but to understand who we are and our moral psychology.
To solve problems now requires our own sacrifice without thinking of our benefit, and not others' sacrifice.
