The country we live in is a laboratory. We have one experiment after another. Unfortunately, it is not a laboratory where no one gets hurt: some lives are enhanced, others are ruined. We have to view our society with concern and passion, and see what we can learn from each of our experiments. When we get upset and angry about politics — whether it is conservative, liberal, or whatever — we tend to think in terms of right and wrong, not what we can learn.
