Sometimes when I listen to fellow progressives, I wonder if the only lesson we took away from the '04 elections is that politics is a word game.

If whiteness were of no particular advantage, then having a fuller color wheel of skin tones would be purely a matter of celebration. But whiteness - just a drop of it - does still carry privilege. You learn that very young in America.

At the heart of our public morality is the idea that he who gives generously is most virtuous and morally praiseworthy; that there is no greater citizen than she who sacrifices; and that there is no greater measure of worth than contribution. These are values we can be proud of. After all, there is no moral system or religion on earth where the guiding ethic is grab more for yourself.

What we should celebrate more than diversity is what we do with it. How do we bring everyone in the tent and create something together? In a twenty-first century way that activates our true potential, we all need to become sworn-again.

Why does an iPhone cost only a couple hundred dollars? Because, as the stage performer Mike Daisey depicted in an arresting one-man show called 'The Agony and Ecstasy of Steve Jobs,' Apple's shiniest products are made by a shadowy company in China called Foxconn.

We tend to think of politics as bad, full of dirty tricks, negative ads, big campaigns, but I am here to explore the original meaning of politics, which is positive and has to do with balancing competing interests and looking for solutions.

If half-black Barack Obama had decided years ago to call himself white - which his genes certainly entitled him to do - his story would have carried very different meaning. If millions of part-black people had followed him into whiteness, then the N.A.A.C.P. would be in true crisis.
