Tilly and Abigail talk with Andy Naselli about the conscience. What is the conscience? What do you do when yours is calibrated differently from your friend's or your husband's? How do you care for your children's sense of right and wrong? How do you care for your own conscience, and what can you do when you realize your conscience has been misguided?

Andy is the co-author of Conscience: What It Is, How to Train It, and Loving Those Who Differ and, for children, author of That Little Voice in Your Head.
