The authoritative single-volume biography of Thomas Jefferson, perhaps the most significant figure in American history. He was a complex and compelling man: a fervent advocate of democracy who enjoyed the life of a southern aristocrat and owned slaves, a revolutionary who became president, a believer in states' rights who did much to further the power of the federal government. Drawing on the recent explosion of Jeffersonian scholarship and fresh readings of original sources, IN PURSUIT OF REASON is a monument to Jefferson that will endure for generations.
