The hero of the beloved Star Wars trilogy is Luke. The principle dynamic is the complicated relationship between Luke and his father. Not coincidentally, George Lucas' last name sounds a lot like Luke. That's the one he identified with. George Lucas had a tumultuous relationship with his own father, and people who know him say that you can't understand the backstory of the movies without knowing that his dad was occasionally difficult but also very loving. They had a big break between them. In those movies, he's very focused on sons and fathers.

I'm also a big Bob Dylan fan. The songs on The Freewheelin' Bob Dylan - which is one of his best early albums - they grow out of some of his difficulties with Suze Rotolo, and "Hard Rain," people say it had to do with the Cuban missile crisis - probably not. He denied it. I believe him, but it certainly had to do with the time.

The sky is always falling or the sky is always bright. In some ways, this is really morning in America and we don't see it. People are living longer, the economy is doing pretty well. On the other hand, there are some ways of thinking in the current situation that make it look not so good, including our Star Wars prequels - like legislature, meaning they're talking a lot, not doing a lot.

I would reject the distinction between a Keynesian moment and a behavioral moment.

There are bursts of things like Abraham Lincoln or Ronald Reagan or Franklin Delano Roosevelt or same-sex marriage that change very much what we thought we were all about.

The idea that Taylor Swift would become the giant pop icon of 2015, 2016 - she's really good, but I don't think it's written in the stars.

Groups become more extreme and entrenched in their beliefs and polarized from others when members only exchange information that reinforces their views and filter out all else or never learn of alternatives. Thus they narrow their options, and magnify each other's prejudices and misconceptions. This trend leads to blind spots in decision making and to extreme behavior, even terrorism.
