Carl Sagan spoke fluently between biology and geology and astrophysics and physics. If you move fluently across those boundaries, you realize that science is everywhere; science is not something you can step around or sweep under the rug.

Those who see the cosmic perspective as a depressing outlook, they really need to reassess how they think about the world. Because when I look up in the universe, I know I'm small but I'm also big. I'm big because I'm connected to the universe, and the universe is connected to me.

I don't think of people as black or white. It's a question of are they photogenic or not? I don't think anyone says, 'Let's book her. She's black.' I think they say, 'Let's book her. She's good.' We've come that far.
