Born to be Good: The Science of Meaningful Life Dacher Keltner If humans are indeed motivated by self-interest, as Adam Smith famously concluded, then what are we to make of the prevalence of emotions like compassion, modesty, and awe in social groups as disparate as the isolated inhabitants of New Guinea and the crowded creatures of New York? Berkeley social psychologist Dacher Keltner argues that the secret to happiness lies in a jen ratio (the balance of good and evil in your life) and demonstrates that the simplest of touches and the slightest of smiles are encoded signals of our innate capacity to engage with others in cooperative communities. By turns personal, informative. Amusing, and instructive, Born to be Good continues Darwin's little-known work on human emotions and shows that survival is actually a matter of who is the kindest. Dacher Keltner is a professor of psychology at the University of California, Berkeley; director for the university's Greater Good Science Center, a research center committed to the scientific understanding of positive emotions; and coeditor of Greater Good magazine.
