The award-winning Lincoln authority Allen C. Guelzo offers here a penetrating look into the mind of one of our greatest presidents. The author takes us on a wide-ranging exploration of seven problems that confronted Lincoln, setting these problems and Lincoln's responses against the larger world of trans-Atlantic liberal democracy in the 19th century, comparing Lincoln not just to Andrew Jackson or John Calhoun, but to British thinkers such as Cobden, Bentham, and Bright, and to French observers de Tocqueville and Guizot.
