Join us as we speak with Dacher Keltner, psychologist and professor at UC Berkeley, and faculty director of The Greater Good Science Center. Keltner is a social psychologist who focuses on the prosocial emotions, such as love, sympathy, compassion and gratitude.  In this video he shares how he, with the help of the Greater Good Science Center, is working to "take the science of compassion and altruism, and getting it out to tens of thousands of people."
