I think it's fantastically narcissistic to believe that in the entire universe, with all of the planetary systems that we've already discovered and the countless others that are out there, that we are the only forms of life.

We don't gaze into a crystal ball. I do not believe that we predict things. I think political science is bad at prediction. I think what we really do well is in a number of instances where politics matters, we can do a better job of tell you what is happening now, than other people. So, we can look at Syria today. We can look at the Eurozone today. And we can look at areas where politics is a driver and we can give you a pretty good sense in those areas of here is how to understand today.

Sometimes you check things off because you've done them. If you aren't checking stuff off your bucket list, you aren't living very well.
