Activists can get very preachy about things. It's more about understanding people's own experiences and tapping into them.

I see [activists] getting really angry that people won't just do what the evidence tells them, and that's not very helpful. You need to actually think why that is.

There's a diversion between economic reality - integration, global village, everybody depending on everybody else - and cultural reality, which is people feeling invaded, undermined, threatened, wanting to have "stand-your-ground" legislation all over the place. It's alarming because at the moment, the fear is outweighing the benefits, and that's partially because the benefits have been so unequally distributed that lots of people don't feel better off. They feel threatened, angry and despairing.

The magic formula is there is no magic formula.

I have to be sure of myself - in a conditional way, always being open to the possibility that I'm wrong.

In the end, that's a blind alley - we have to get back to being able to think on our feet and react.
