This looks like an interesting book (from:http://www.psychologytoday.com/rss/pto-20090115-000009.html).
Born to Be Good
By Dacher Keltner
Through
his studies on facial movements, tones of voice, goosebumps, dinosaurs,
and beauty, Berkeley psychologist Keltner has forged what he calls a
“new science of positive emotion.” His conclusion: Human beings have
evolved a set of positive emotions—gratitude, mirth, awe, and
compassion—and it is these that enable us to lead meaningful lives. The
key to happiness, he says, is to let these emotions arise in ourselves
and to evoke them in others. Human beings are wired to be good—so much
so, Keltner says, that the best way to describe our origins is not
“survival of the fittest” but “survival of the kindest.” —Jay Dixit
