Lincoln's story confounds those who see depression as a collection of symptoms to be eliminated. But it resonates with those who see suffering as a potential catalyst of emotional growth. "What man actually needs," the psychiatrist Victor Frankl argued,"is not a tension-less state but rather the striving and struggling of a worthwhile goal." Many believe that psychological health comes with the relief of distress. But Frankl proposed that all people-- and particularly those under some emotional weight-- need a purpose that will both draw on their talents and transcend their lives. For Lincoln, this sense of purpose was indeed the key that unlocked the gates of a mental prison. This doesn't mean his suffering went away. In fact, as his life became richer and more satisfying, his melancholy exerted a stronger pull. He now responded to that pull by tying it to his newly defined sense of purpose. From a place of trouble, he looked for meaning. He looked at imperfection and sought redemption.
