In January 1841, Abraham Lincoln seems to have at least vaguely thought of suicide. His friend Joshua Speed found him one day thrashing about in his room. “Lincoln went Crazy,” Speed wrote. “I had to remove razors from his room — take away all knives and other such dangerous things — it was terrible.” Lincoln was taking three mercury pills a day, the remedy in those days for people who either suffered from syphilis or feared contracting it. “Lincoln could not eat or sleep,” Daniel Mark Epstein writes in his new book, “The Lincolns.” “He appeared at the statehouse irregularly, hollow-eyed, unshaven, emaciated — an object of pity to his friends and of derision to others.” Later, Lincoln wrote of that period with shame, saying that he had lost the “gem of my character.” He would withdraw morosely from the world into a sort of catatonic state. Early in his marriage, Epstein writes, “Lincoln had night terrors. He woke in the middle of the night trembling, talking gibberish.” He would, of course, climb out of it. He would come to terms with his weaknesses, control his passions and achieve what we now call maturity. The concept of maturity has undergone several mutations over the course of American history. In Lincoln's day, to achieve maturity was to succeed in the conquest of the self. Human beings were born with sin, infected with dark passions and satanic temptations. The transition to adulthood consisted of achieving mastery over them. You can read commencement addresses from the 19th and early 20th centuries in which the speakers would talk about the beast within and the need for iron character to subdue it. Schoolhouse readers emphasized self-discipline. The whole character-building model was sin-centric. So the young Lincoln had been encouraged by the culture around him to identify his own flaws — and, in any case, he had no trouble finding them. He knew he was ferociously ambitious and blessed with superior talents — the sort of person who could easily turn into a dictator or monster. Over the course of his young adulthood, Lincoln built structures around his inner nature. He joined a traditional bourgeois marriage. He called his wife “mother” and lived in a genteel middle-class home. He engaged in feverish bouts of self-improvement, studying Euclid and grammar at all hours. He distrusted passionate politics. In the Lyceum speech that he delivered as a young man, he attacked emotionalism in politics and talked about the need for law, order and cool reason. This concept of maturity as self-conquest didn't survive long into the 20th century. Progressive educators emphasized students' inner goodness and curiosity, not inner depravity. More emphasis was put on individual freedom, authenticity and values clarification. Self-discovery replaced self-mastery as the primary path to maturity, and we got a thousand novels and memoirs about young peoples' search for identity. In the last few years, we may be shifting toward another vision of maturity, one that is impatient with boomer narcissism. Young people today put service at the center of young adulthood. A child is served, but maturity means serving others. And yet, though we're never going back to the 19th-century, sin-centric character-building model, for breeding leaders, it has its uses. Over the past decades, we've seen president after president confident of his own talents but then undone by underappreciated flaws. It's as if they get elected for their virtues and then get defined in office by the vices — Clinton's narcissism, Bush's intellectual insecurity — they've never really faced. It would be nice to have a president who had gone to school on his own failings. It would be comforting to see a president who'd looked into the abyss, or suffered some sort of ordeal that put him on a first-name basis with his own gravest weaknesses, and who had found ways to combat them. Obviously, it's not fair to compare anybody to Lincoln, but he does illustrate the repertoire of skills we look for in a leader. The central illusion of modern politics is that if only people as virtuous as “us” had power, then things would be better. Candidates get elected by telling people what they want to hear, leading them by using the sugar of their own fantasies. Somehow a leader conversant with his own failings wouldn't be as affected by the moral self-approval that afflicts most political movements. He'd be detached from his most fervid followers and merciful and understanding toward foes. He'd have a sense of his own smallness in the sweep of events. He or she would contravene Lord Acton's dictum and grow sadder and wiser with more power. All this suggests a maxim for us voters: Don't only look to see which candidate has the most talent. Look for the one most emotionally gripped by his own failings. – The New York Times __
