Three thousand years ago on a battlefield in ancient Palestine, a shepherd boy felled a mighty warrior with nothing more than a pebble and a sling-and ever since, the names of David and Goliath have stood for battles between underdogs and giants. David's victory was improbable and miraculous. He shouldn't have won. Or should he? In DAVID AND GOLIATH, Malcolm Gladwell challenges how we think about obstacles and disadvantages, offering a new interpretation of what it means to be discriminated against, suffer from a disability, lose a parent, attend a mediocre school, or endure any number of other apparent setbacks.
