The communists basically acted as the police force of the security system of the [Spain] Republic and were very much opposed to the anarchists, partially because [Joseph] Stalin still hoped at that time to have some kind of pact with Western countries against [Adolf] Hitler. That, of course, failed and Stalin withdrew the support to the Republic. They even withdrew the Spanish gold reserves.

If humans are organisms like every other organism - which they are - then we should expect that if there are some domains where real scientific progress is possible, then there are others where it is not.

When Israelis in the occupied territories now claim that they have to defend themselves, they are defending themselves in the sense that any military occupier has to defend itself against the population they are crushing. You can't defend yourself when you're militarily occupying someone else's land. That's not defense. Call it what you like, it's not defense.

I think the most important work that is going on has to do with the search for very general and abstract features of what is sometimes called universal grammar: general properties of language that reflect a kind of biological necessity rather than logical necessity; that is, properties of language that are not logically necessary for such a system but which are essential invariant properties of human language and are known without learning. We know these properties but we don't learn them. We simply use our knowledge of these properties as the basis for learning.

Terror became a big issue when the Reagan Administration came in. They immediately announced [their plans] and kind of disparaged Carter's alleged human rights programs. The main issue is state-directed international terrorism. Right at that time that big industry developed. That's when you start getting the academic departments on terrorism.

Iceland is capitalist social democratic, rather like the Nordic countries generally. The capital had a mayor who is an anarchist, but the city has been nothing like that. In fact a few years ago it was super-neoliberal, which led to the crash.

[Donald] Trump has been very inconsistent on many things; on Twitter he's been all over the place, but some of it is very consistent. That is: Do nothing about climate change except make it worse. And he's not just speaking for himself, but for the whole Republican Party, the whole leadership. It's already had impact, it will have worse impact.
