If partisanship makes us abandon intellectual honesty, if we oppose what our opponents say or do simply because they are the ones saying or doing it, we become mere political short-sellers, hoping for bad news because it's good for our ideological investment.

I am proud to be American. We wouldn't have our big dreams without this quality, but if we can't agree on the shape of reality, when a White House, on the second day of a new administration, is arguing for alternative facts, that's problematic.

Because we don't know that much about what has happened before, it's useful. But either we will recover and progress, or the alternative is that it's all downhill from here. So I would just as soon believe, in my optimistic Midwestern American way, that we will recover and maybe even make lemonade out of the lemons that we are faced with.

TED was simply wonderful, an intellectual spa, a 21st-century Chataqua, superb and singular.
