Recent research indicates that differences in our society on issues such as global
warming, defense spending, immigration, and gay rights is, to some extent,
deeply rooted in neurobiological differences, particularly in regard to the prefrontal
cortex and the amygdala. If the brains of liberals and conservatives tend to function
differently, is there a path toward reconciliation? What are some of the ways pointing towarda more perfect union? Are there ancient mythologies of war and peace that illustrate our genetic variation and offer hope for humanity?
