The code was based on the same premise as the nation’s Constitution — that human beings are flawed creatures who live in constant peril of falling into disasters caused by their own passions. Artificial systems have to be created to balance and restrain their desires.
The dignity code commanded its followers to be disinterested — to endeavor to put national interests above personal interests. It commanded its followers to be reticent — to never degrade intimate emotions by parading them in public. It also commanded its followers to be dispassionate — to distrust rashness, zealotry, fury and political enthusiasm.

Remnants of the dignity code lasted for decades. For most of American history, politicians did not publicly campaign for president. It was thought that the act of publicly promoting oneself was ruinously corrupting. For most of American history, memoirists passed over the intimacies of private life. Even in the 19th century, people were appalled that journalists might pollute a wedding by covering it in the press.
Today, Americans still lavishly admire people who are naturally dignified, whether they are in sports (Joe DiMaggio and Tom Landry), entertainment (Lauren Bacall and Tom Hanks) or politics (Ronald Reagan and Martin Luther King Jr.).

First, there was Mark Sanford’s press conference. Here was a guy utterly lacking in any sense of reticence, who was given to rambling self-exposure even in his moment of disgrace. Then there was the death of Michael Jackson and the discussion of his life. Here was a guy who was apparently untouched by any pressure to live according to the rules and restraints of adulthood. Then there was Sarah Palin’s press conference. Here was a woman who aspires to a high public role but is unfamiliar with the traits of equipoise and constancy, which are the sources of authority and trust.

Americans still admire dignity. But the word has become unmoored from any larger set of rules or ethical system.
But it’s not right to end on a note of cultural pessimism because there is the fact of President Obama. Whatever policy differences people may have with him, we can all agree that he exemplifies reticence, dispassion and the other traits associated with dignity. The cultural effects of his presidency are not yet clear, but they may surpass his policy impact. He may revitalize the concept of dignity for a new generation and embody a new set of rules for self-mastery. ..snip
