That's what I learned from World War II. Things are always more complicated than most people believe.

It's not going to be just humans colonizing space, it's going to be life moving out from the Earth, moving it into its kingdom. And the kingdom of life, of course, is going to be the universe.

Do not imagine that you have to know everything before you can do anything. My own best work was done when I was most ignorant.

If you start out with a tragic view of life, then anything since is just a bonus.

You ask: what is the meaning or purpose of life? I can only answer with another question: do you think we are wise enough to read God's mind?

As finite creatures who think and feel, we can create islands of meaning in the sea of information.

In the future, a new generation of artists will be writing genomes as fluently as Blake and Byron wrote verses.
