"Tyson emails back: "I'm going to tell you the same thing that I told Henry Louis Gates" (Gates had asked Tyson to appear on his show Finding Your Roots): My philosophy of root-finding may be unorthodox. I just don't care. And that's not a passive, but active absence of caring. In the tree of life, any two people in the world share a common ancestor--depending only on how far back you look. So the line we draw to establish family and heritage is entirely arbitrary. When I wonder what I am capable of achieving, I don't look to family lineage, I look to all human beings. That's the genetic relationship that matters to me. The genius of Isaac Newton, the courage of Gandhi and MLK, the bravery of Joan of Arc, the athletic feats of Michael Jordan, the oratorical skills of Sir Winston Churchill, the compassion of Mother Teresa. I look to the entire human race for inspiration for what I can be--because I am human. Couldn't care less if I were a descendant of kings or paupers, saints or sinners, the valorous or cowardly. My life is what I make of it." --
