Sean Carroll in Preposterous Universe:
Within every person’s mind there is on ongoing battle between reason and emotion. It’s not always a battle, of course; very often the two can work together. But at other times, our emotions push us toward actions that our reason would counsel against. Paul Bloom is a well-known psychologist and author who wrote the provocatively-titled book Against Empathy: The Case for Rational Compassion, and is currently writing a book about the nature of cruelty. While I sympathize with parts of his anti-empathy stance, I try to stick up for the importance of empathy in the right circumstances. We have a great discussion about the relationship between reason and emotion.
