In this, his last work, J. David Greenstone provides an important new analysis of American liberalism and of Lincoln's unique contribution to the nation's political life. Greenstone addresses Louis Hartz's well-known claim that a tradition of liberal consensus has characterized American political life from the time of the founders. Although he acknowledges the force of Hartz's thesis, Greenstone nevertheless finds it inadequate for explaining prominent instances of American political discord, most notably the Civil War.In this, his last work, J.
