A lawyer and scholar from Indiana, Joshua Claybourn deeply understands Lincoln's rural roots, legal mode of thinking, and moral clarity. With a vivid clarity, Claybourn illuminates the key to Lincoln's thought: the equal human rights promised by the Declaration of Independence as the foundation of our nation. We could have a more just and enduring republic, if all Americans would read and reflect on Lincoln's Compass.

A superb explanation of how Lincoln turned America into a creedal nation.

Lincoln was that rare species – a politician with a profound moral compass. Joshua Claybourn's investigation takes us on a journey to find the sources and principles of that compass, and does so in an eloquent and highly personable fashion. We can all profit from reading the words of Lincoln; we can profit still more from understanding the moral roots of those words, and Claybourn's Lincoln is the clearest set of guideposts on that journey.

In this sweeping, brilliant book, Joshua Claybourn reveals how the Declaration's pronouncement of human equality was transformed by Lincoln into the lodestar for civil rights advocacy, from his own presidency to modern times. Lincoln's Compass is an inspiring, essential contribution to our understanding of the American experiment.

One of the best ways to think about the Declaration of Independence is to watch Abraham Lincoln think about it -- and Joshua Claybourn has given us an unprecedented front-row seat. In this timely and lively book, Claybourn reveals how deeply Lincoln studied the Declaration (and how much our current understanding of this document depends on Lincoln's lawyerly work). Lincoln's Compass does not trace the president's full life. It does something better by zooming in on key moments, on how the sunlight feels in southern Indiana, on how Enlightenment ideas should matter to every American. This book shows why Lincoln, a writer so good at describing the metaphorical beauty of history -- its better angels, its mystic chords -- in the end relied most on a simple declarative phrase: All men are created equal.
