And so it's no surprise that people who object to the death penalty on pure moral grounds also think it has no deterrent effect, and people who like the death penalty on grounds of retribution tend to think it has deterrent effects. They like that, and they believe that. I think with climate change we're seeing very much the same thing where those who deny climate change, they don't like that, and they don't believe it.

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

If Star Wars had been released in the late '60s, or late '80s, or late '90s, adjusting for technology, it fits spectacularly well.

Star Wars may be kind of a cartoon, but the original trilogy depicts a political paralysis which breeds an interest in a strong leader who will make a significant break with the past. And Hillary Clinton is a person - whether you like it or not - of extraordinary experience. I don't know if we ever had a presidential candidate with that level of political experience. There's no learning curve for her. And that, in some periods, would be a huge plus. In the end, I think it will be a significant plus for her now.

On reflection, some things do super well because they hit with the time. Some things do super well because they are able to activate a kind of echo chamber or bandwagon or cascade - they didn't particularly hit with the time. Some things are just too astonishingly good to not hit the top. Those three explanations, with respect to the Star Wars phenomenon, seem to me all to pass the plausibility test, and to explore them, with respect to Star Wars, I think casts light not just on the saga of our time, but also on everything about our culture.

A well-functioning democracy has a culture of free speech, not simply legal protection of free speech. It encourages independence of mind. It imparts a willingness to challenge prevailing opinion through both words and deeds. Equally important, it encourages a certain set of attitudes in listeners, one that gives a respectful hearing to those who do not embrace the conventional wisdom. In a culture of free speech, the attitude of listeners is no less important than that of speakers.

If you have a regulation that's going to save hundreds of thousands of lives annually and not cost very much, that sounds like a very good idea.
