You can see the rider serving the elephant when people are morally dumbfounded. They have strong gut feelings about what is right and wrong, and they struggle to construct post hoc justifications for those feelings.

Jonathan HaidtI 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.
