My parents were nonmaterialistic. They believed that money without knowledge was worthless, that education tempered with religion was the way to climb out of poverty in America, and over the years they were proven right.

There has to be some mystery in life, because the joy of being a writer and the joy of being a musician is the joy of discovery. I don't want someone discovering for me what I should be discovering on my own. If a person is discovering for me, then they're living for me. It's my responsibility, indeed it's my privilege, to go out and discover the world for myself.

Most white people didn't own slaves. Slavery was a way of life, just like driving cars is a way of life now. It doesn't mean that it was right.

It is hard to find romance in the present because there's nothing left to the imagination.
