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.

So, I subscribe to the following reading: Star Wars is an essentially Christian tale.

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.

My role in the government was not to think about narratives and consistency with narratives, but think of the human consequences of rules.

The 'cash for clunkers' program was a big success in part because it gave people the sense that the economy was moving.

My friend jewelry designer Courtney Crangi has been obsessed with Star Wars all her life and has seen the movies 150 times. When we first started talking about it, I was amazed that her knowledge made mine - which was even then pretty impressive - seem pathetic. And I think there are a couple of reasons for this. One is that the leader of the rebellion is Princess Leia. American theatergoers had never seen a princess like that. She's not a delicate flower, she's not passive, she's often the only one who has a clue.

There is no reason to believe that in the face of statutory ambiguity, the meaning of federal law should be settled by the inclinations and predispositions of federal judges. The outcome should instead depend on the commitments and beliefs of the President and those who operate under him.
