As for the various religions, there's no doubt that they are very meaningful to adherents, and allow them to delude themselves into thinking there is some meaning to their lives beyond what we agree is the case. I'd never try to talk them out of the delusions, which are necessary for them to live a life that makes some sense to them. These beliefs can provide a framework for deeds that are noble or savage, and anywhere in between, and there's every reason to focus attention on the deeds and the background for them, to the extent that we can grasp it.

Remember that in any major nuclear war, the first strike destroys the country that attacks; it's been known for years. The first strike of a major power is very likely to cause what's called nuclear winter, leads to global famine for years and everything's basically gone. Some survivors straggling around. Could [Donald Trump] do it? Who knows.

We still name our military helicopter gunships after victims of genocide. Nobody bats an eyelash about that: Blackhawk. Apache. And Comanche. If the Luftwaffe named its military helicopters Jew and Gypsy, I suppose people would notice.

Bradley Manning should be regarded as a hero. He is doing what an honest, decent citizen should be doing: letting your population know what the government, the people who rule you are doing. They want to keep it secret of course.

Human physical structures and intellectual structures are generally studied in different ways. The assumption is that physical structures are genetically inherited and intellectual structures are learned. I think that this assumption is wrong. None of these structures is learned. They all grow; they grow in comparable ways; their ultimate forms are heavily dependent on genetic predispositions.

Citizenship means every four years you put a mark somewhere and you go home and let other guys run the world. It's a very destructive ideology.

There is still much debate about whether torture has been effective in eliciting information - the assumption being, apparently, that if it is effective, then it may be justified.
