"David and Goliath is a book about what happens when ordinary people confront giants. By "giants," I mean powerful opponents of all kinds--from armies and mighty warriors to disability, misfortune, and oppression. Each chapter tells the story of a different person--famous or unknown, ordinary or brilliant--who has faced an outsize challenge and been forced to respond. Should I play by the rules or follow my own instincts? Shall I persevere or give up? Should I strike back or forgive? Through these stories, I want to explore two ideas. The first is that much of what we consider valuable in our world arises out of these kinds of lopsided conflicts, because the act of facing overwhelming odds produces greatness and beauty. And second, that we consistently get these kinds of conflicts wrong. We misread them. We misinterpret them. Giants are not what we think they are. The same qualities that appear to give them strength are often the sources of great weakness. And the fact of being an underdog can change people in ways that we often fail to appreciate: it can open doors and create opportunities and educate and enlighten and make possible what might otherwise have seemed unthinkable."
