How many educated Americans can even remember the names of the assassinated Jesuit intellectuals of El Salvador, or would know where to find a word they wrote? The answers are revealing, particularly when we draw the striking - and historically typical - contrast to the attitudes towards their counterparts in enemy domains.

You can read it in history books now, but they often suppress the fact that the U.S. government tolerated [Nazi]. It's really remarkable because they claim that [Franklin] Roosevelt was impeded by the Neutrality Act. On the other hand, he bitterly condemned a Mexican businessman for sending several guns to the Republic. If you look back, oil was the one commodity that [Francisco] Franco could not receive from the Germans and the Italians, so that was quite significant.

The US is a country [in which] eighty percent of the population thinks the Bible was written by god. About half think every word is literally true. So it's had to appeal to that - and to the nativist population, the people that are frightened, have always been... It's a very frightened country and that's increasing now with the recognition that the white population is going to be a minority pretty soon, "they've taken our country from us."

Scientists generally, not just evolutionary biologists, don't take much for granted.

Very commonly I get queries. Somebody saw something of mine on YouTube and of course if there is a talk on YouTube, there aren't any footnotes - and they want to know why did you say this. Well if they bothered to look up something in print, they would've seen why I said that. If they ask for evidence, I just say well take a look and mention something they can read and that usually ends the conversation.

I think that has a lot of dangers, as does government surveillance, which is way too high.

In the early days of the military Arpanet, my daughter was studying in Nicaragua. Because the U.S. was essentially at war with them, contact was difficult. I managed to use MIT's Arpanet connection, and she found one, so we could communicate thanks to the Pentagon!
