Anarchism, in my view, is an expression of the idea that the burden of proof is always on those who argue that authority and domination are necessary. They have to demonstrate, with powerful argument, that that conclusion is correct. If they cannot, then the institutions they defend should be considered illegitimate. How one should react to illegitimate authority depends on circumstances and conditions: there are no formulas.

When I look at public opinion, I'm not far out of the mainstream. I'm in it, in many respects. In some respects, public opinion goes beyond anything I've ever said.

If [climate change ] became a serious proposal in the United States, there would be a huge propaganda onslaught by the business community, the energy corporations and many others, to try to frighten the population into opposing it - claiming that if they have it, all sorts of terrible things will happen, like you won't be able to heat your home, or whatever the story is.

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.

If you want to become a biologist, it doesn't help to go into the Harvard biology library and all the information is there for you. You have to know what to look for and the internet is the same, just magnified.

US government policies are continuing to do exactly the same thing [produce terrorism]. Two days after the Boston marathon bombings, there was a drone strike in Yemen attacking a peaceful village, which killed a target who could very easily have been apprehended. But of course it is just easier to terrorise people.

I think half the population supports this ban on these dangerous immigrants who are going to come in and do something, who knows what. And meanwhile the countries that really have been involved in terrorism, they're out. It's kind of like I think it was Oklahoma banning Sharia law.
