A second legacy from Nancy might seem more a curse than a gift, but it may have helped to give us the Lincoln our nation reveres. She would pass on to him her own struggle with depression, with that enveloping darkness that lurks, for some, ever at the soul's door. This would merge with a Lincoln family heritage of mental illness to become a force in Abraham that he fought to subdue all his days. It would leave him scarred, and it would even deform parts of his personality, but by striving to master it and by remembering what he had experienced in those hours of suffocating gloom, he emerged a man of greater wisdom, wit, and humanity.
