There is no evolutionary pressure to create minds capable of forming sciences; it just happened. Evolutionary pressure has not led to higher rates of reproduction for people capable of solving scientific problems or creating new scientific ideas. So if, in fact, the science-forming capacities evolved for other reasons, it would not be too surprising if those particular structures that have developed proved to be rather special in their nature, reflecting the contingencies of their evolution or the working of physical law.

I can understand the idea that there is a conspiracy. In fact, in much of the world there is a sense of an ultra-powerful CIA manipulating everything that happens, such as running the Arab Spring, running the Pakistani Taliban, etc. That is just nonsense. They [CIA] created a monster and now they are appalled by it.

We don't think about it, but it has a tremendous effect. But these are things you don't see right in front of your eyes. You need to think about them a little, to see what the consequences are.

You win by struggle, and that requires understanding and serious analysis of the options and the circumstances, and then you can do a lot.

U.S. domestic drug policy does not carry out its stated goals, and policymakers are well aware of that. If it isn't about reducing substance abuse, what is it about? It is reasonably clear, both from current actions and the historical record, that substances tend to be criminalized when they are associated with the so-called dangerous classes, that the criminalization of certain substances is a technique of social control.

You keep plugging away--that's the way social change takes place. That's the way every social change in history has taken place: by a lot of people, who nobody ever heard of, doing work.

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.
