For the first time in his public life, [Lincoln’s] remarkable array of gifts as historian, storyteller, and teacher combined with a lucid, relentless, yet always accessible logic. Instead of the ornate language so familiar to men like Webster, Lincoln used irony and humor, laced with workaday, homespun images to build an eloquent tower of logic….Such flashes of figurative language were always available to Lincoln to drive home a point, gracefully educating while entertaining—in a word, communicating an enormously complicated issue with wit, simplicity, and a massive power of moral persuasion.
