Book excerpt: Abraham Lincoln drew upon history in his political career and particularly when crafting the rhetorical masterpieces that still resonate in the present day. Jesse Derber explores how Lincoln’s views of the limits of human understanding drove a belief in--and untiring pursuit of--historical truth. Lincoln embraced the traditional ideas that good history made good statesmanship and that an understanding of the past informed decision-making in the present. Seeing history as a source of wisdom, Lincoln strove for accuracy through a combination of research, reasoning ability, emotional maturity, and a willingness to admit his mistakes and challenge his biases. His philosophy flowed from an idea that authentic history could enlighten people about human nature. Though he revered precedents, Lincoln understood the past could be imperfect, and that progress through change was an ineffable part of building a better nation. Perceptive and revealing, Abraham Lincoln, Statesman Historian looks at how the Lincoln practiced history and applied its lessons to politics and leadership.
