If I have a mission in life, it is to convince people that everyone is morally motivated - everyone except for psychopaths.

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.

In real life, however, you don't react to what someone did; you react only to what you think she did, and the gap between action and perception is bridged by the art of impression management. If life itself is but what you deem it, then why not focus your efforts on persuading others to believe that you are a virtuous and trustworthy cooperator?

Love and work are to people what water and sunshine are to plants.

When you hear someone criticize a policy on the other side, thats fine. But when you start hearing motive-mongering and demonization, stand up to it just as you would if it were something that was racist or sexist. If we avoid the demonization, disagreements can be positive.

Diversity is not a virtue. Diversity is a good only to the extent that it advances other virtues, justice or inclusiveness of others who have previously been excluded.

People are wrong when they say that everything should be more diverse, even, say, rock bands. It's an error, an overgeneralization.
