Obama sees the world in two ways: from the black perspective and from the white perspective. He was raised as a black man, whose culture he has self-consciously adopted. But he was reared largely by his white grandparents. He lived a kind of racially bipartisan experience, and he will be able to speak a language that resonates with both communities.

Gangsta rap often reaches higher than its ugliest, lowest common denominator, misogyny, violence, materialism and sexual transgression are not its exclusive domain. At its best, this music draws attention to complex dimensions of ghetto life ignored by most Americans. Indeed, gangsta rap's in-your-face style may do more to force America to confront crucial social problems than a million sermons or political speeches.

Even when you don't know, you're supposed to know.

The culture will not be able to persist in light of the rigid systems of its own innocence.

Charity is no substitute for justice.

We must never ignore the injustices that make charity necessary, or the inequalities that make it possible.
