I think moral philosophy is speculation on how we ought to live together done by people who have very little clue how people work. So I think most moral philosophy is disconnected from the species that we happen to be. In fact, they like it that way. Many moral philosophers insist that morality grows out of our rationality, that it applies to any rational being anywhere in the universe, and that it is not based on contingent or coincidental facts about our evolution.

We are like a rider on top of a gigantic elephant. We can steer the elephant, and if he's not busy, he'll go where we want, but if he has other desires, he'll often go where he wants. How can one control the elephant? In part, this comes with maturity. In part, this comes with the development of your frontal cortex, so the frontal areas of the brain are especially involved in self-control, in suppressing your initial instinct to act. This is why teenagers are so impulsive. So it's terrible to allow the death penalty for teenagers, because they really don't have working brains yet.

Human rationality depends critically on sophisticated emotionality. It is only because our emotional brain works so well that our reasoning can work at all.

I think that we are passionate creatures who really live our fullest life when we are deeply engaged, when we feel successes, and exult in them, when we feel losses and tragedies and are hurt by them. So I came to the conclusion that Eastern ideas of withdrawal may not be right for modern Westerners. If you read the ancient texts, they're pretty severe. I mean, they really are not the sort of thing that you would think compatible with really throwing yourself into life and being a part of it.

Liberals tend to be much more concerned about business and corporations as the oppressors. They look to government as the solution. On the Right it's the opposite. They see business as good, as what generates wealth in society, and they see government as the oppressor, which makes it hard for especially small businesspeople.

Morality binds and blinds. It binds us into teams … but thereby makes us go blind to objective reality.

Morality binds and blinds. It binds us into ideological teams that fight each other as though the fate of the world depended on our side winning each battle. It blinds us to the fact that each team is composed of good people who have something important to say.
