In “this inventive and playful book” (Tom Beer, Newsday), James Geary explores every facet of wittiness, from its role in innovation to why puns are the highest form of wit. Adopting a different style for each chapter—from dramatic dialogue to sermon, heroic couplets to a barroom monologue—Geary embodies wit in all its forms. Wit’s End agilely balances psychology, folktale, visual art, and literary history with lighthearted humor and acute insight, demonstrating that wit and wisdom are really the same thing.
