I thought Barack Obama's speech was strong, thoughtful and important. Rather beautifully, it was a speech to think to, not clap to. It was clear that's what he wanted, and this is rare.

It seemed to me as honest a speech as one in his position could give within the limits imposed by politics. As such it was a contribution. We'll see if it was a success. The blowhard guild, proud member since 2000, praised it, and, in the biggest compliment, cable news shows came out of the speech not with jokes or jaded insiderism, but with thought. They started talking, pundits left and right, black and white, about what they'd experienced of race in America. It was kind of wonderful. I thought, Go, America, go, go.

You know what Mr. Obama said. The Rev. Jeremiah Wright was wrong. His sermons were "incendiary," and they "denigrate both the greatness and the goodness of our nation." Mr. Obama admitted that if all he knew of Mr. Wright were what he saw on the "endless loop . . . of YouTube," he wouldn't like him either. But he's known him 20 years as a man who taught him Christian faith, helped the poor, served as a Marine, and leads a community helping the homeless, needy and sick. "As imperfect as he may be, he has been like family to me." He would not renounce their friendship.

Most significantly, Mr. Obama asserted that race in America has become a generational story. The original sin of slavery is a fact, but the progress we have lived through the past 50 years means each generation experiences race differently. Older blacks, like Mr. Wright, remember Jim Crow and were left misshapen by it. Some rose anyway, some did not; of the latter, a "legacy of defeat" went on to misshape another generation. The result: destructive anger that is at times "exploited by politicians" and that can keep African-Americans "from squarely facing our own complicity in our condition." But "a similar anger exists within segments of the white community." He speaks of working- and middle-class whites whose "experience is the immigrant experience," who started with nothing. "As far as they're concerned, no one handed them anything, they've built it from scratch." "So when they are told to bus their children to a school across town," when they hear of someone receiving preferences they never received, and "when they're told their fears about crime in urban neighborhoods are somehow prejudiced," they feel anger too.

This is all, simply, true. And we are not used to political figures being frank, in this way, in public. For this Mr. Obama deserves deep credit. It is also true the particular whites Obama chose to paint -- ethnic, middle class -- are precisely the voters he needs to draw in Pennsylvania. It was strategically clever. But as one who witnessed busing in Boston first hand, and whose memories of those days can still bring tears, I was glad for his admission that busing was experienced as an injustice by the white working class. Next step: admitting it was an injustice, period.
