Read the full transcriptWhen (if ever) can suffering be good? Is there an optimal ratio of pleasure to pain? What is motivational pluralism? Can large, positive incentives be coercive? (For example, is it coercive to offer to pay someone enormous amounts of money to do something relatively benign or even painful or immoral?) How can moving from making judgments about a person's actions to making judgments about their character solve certain moral puzzles? Why do we sometimes make seemingly irrational judgments about the relative badness of certain actions? How does the level of controversy around an action factor into how much we publicly disapprove of it? What are the differences between compassion and empathy? Is antisocial personality disorder (AKA psychopathy or sociopathy) defined only by a lack of empathy? How have humans evolved (or not) to detect and mitigate the effects of others who feel no remorse? Is altruism especially vulnerable to remorseless people? What are the differences between narcissists and sociopaths?Paul Bloom is Professor of Psychology at the University of Toronto, and Brooks and Suzanne Ragen Professor Emeritus of Psychology at Yale University.
