We naturally assume that our mental structures are universal. But I suppose an outside biologist looking at us would see something very different. He would see that, like other organisms, we have a narrow sphere within which we are very good, but that sphere is very limited. And that, in fact, the very achievements we can have within that sphere are related to lack of achievements in other spheres.

One of the dangers [that Donald Trump poses, due to the augmented risk of nuclear war] is unquestionable. Of the two existential threats - the threats to the termination of the species basically and most other species - one of them, climate change, on that I think there's no basis for discussion.

Another recollection is that [ Paul Johnson] mostly kept away from ideas and dedicated activism, and concentrated on sex lives and other gossip.

There's an interesting question, whether the anarchists had alternatives [in Spain]. If they did tend to support the government that had been destroyed, what were the alternatives? There was actually a proposal by Camillo Berneri, an Italian anarchist who was in Spain at the time, which is not a crazy notion in my opinion. He opposed participation in government and was against the formation of an army, meaning a major army to fight [Francisco] Franco.

If the most important revolutionary part of the George W. Bush Doctrine is that states that harbor terrorists are terrorist states, what do we conclude from that? We conclude exactly what Kissinger was kind enough to say: These doctrines are unilateral. They are not intended as doctrines of international law or doctrines of international affairs. They are doctrines that grant the U.S. the right to use force and violence and to harbor terrorists, but not anyone else.

The most dramatic case is that of the Central Americans. Why are people fleeing Central America? It's because of the atrocities the U.S. committed there. Take Boston, where there's a fairly large Mayan population. These people are fleeing from the highlands of Guatemala, where there was virtual genocide in the early 1980s backed by Ronald Reagan. The region was devastated, and people are still fleeing to this day, yet they're sent back.

It was during the Reagan years that defiance of international law and the U.N. Charter became entirely open.
