Combining history, psychology, and anthropology, Tribe explores what we can learn from tribal societies about loyalty, belonging, and the eternal human quest for meaning. It explains the irony that-for many veterans as well as civilians-war feels better than peace, adversity can turn out to be a blessing, and disasters are sometimes remembered more fondly than weddings or tropical vacations. Tribe explains why we are stronger when we come together, and how that can be achieved even in today's divided world.
