The book makes two arguments about what babies tell us about adult morality. One is a lot of morality is inborn. It's hardwired. We're born with it. The second thing I argue is that this is limited. That some moral rule should apply across the board. Does not come natural to us. And so what I do is I discuss baby research. Some of it done at Yale with my wife Karen. And other labs across the world that show that babies have this remarkable moral sense. They are they have capable of empathy, of moral outrage, of judging good and evil. They have an appetite for punishment for reward. There's a powerful moral system built in early on.
