George Vaillant is a psychiatrist and Harvard professor who, for 35 years, led Harvard’s 70+ year Study of Adult Development. (You learn a thing or three when you follow the development of teenagers as they grew into great-grandparents.) In this book, he tells us that we can evolve spiritually. Leaning on his experience running Harvard’s study plus cultural anthropology, ethology and neuroscience, he walks us through the biological underpinnings of the positive emotions that make up our spirituality: faith, love, hope, joy, forgiveness, compassion and awe.
