Probably, if we looked at Da Vinci or Michelangelo with care, we'd see a historical particularity that the work is not treated as having. It's certainly true of Shakespeare.

Even though Star Wars is easily read as feminist for its time - and even for now, with Princess Leia's role - people wouldn't make a movie like that in 2016, where the guys are mostly the tough ones, and the women aren't in positions of authority.

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.

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

Those who believe in climate change, as I do, I think it's also fair to say that they are more receptive to confirming evidence than disconfirming evidence. They happen to be right, but their motivations are in play also.

It's deeply human to do both the worst things and the best things because of your fear of loss.

The fear of loss is an engine of horrors, but also a source of the greatest forms of heroism. There's not a lot of art that puts that in bold letters. It's psychologically very interesting and acute, I think. That's not the central reading, I think, of the New Testament.
