I've spoken to Paul Bloom previously about the precocious moral awareness of young infants and the ingenious experiments used to demonstrate it. Now Paul has synthesized those findings in a far-reaching exploration of our ethical capacities and limitations. His new book is "Just Babies: The Origins of Good and Evil" Topics covered in this interview include:

-Are we born with a sense of right and wrong?

-Gut feelings vs. rational deliberation as a basis for ethical behavior

-The roots of racism

-Mafia morality

-Sitcoms and moral uplift
