We need to sacrifice something. And this is what I find lacking. We want to construct an image of ourselves as virtuous but we don't want to suffer for our beliefs. We want to change the world with a Facebook like. That's not how the world works.

There are realities that one needs to deal with, but very often what we are told is political reality is merely cynicism. One could equally say that slavery is a reality, and misogyny too.

When we deconstruct how radical evil occurs we realize that it is anything but spontaneous combustion. You need pyromaniacs.

In Yugoslavia we were told we were not only naive idealists in wanting war criminals to be prosecuted but that we were actually standing in the way of a ceasefire which would save more lives. The idea was that, by giving amnesty to these ruthless warmongers, you would give them an incentive to stop killing. I found that incredibly naive, never mind cynical. Having been on the ground and having met with these ruthless killers, I knew the only thing they understood was the language of force.

Storytelling is very important. It is through context and relations that we understand the importance of human dignity. The concept means nothing as an abstraction. It's important for us to understand why people do the things they do, including the monsters - the suicide bomber and the war criminal. Understanding is not acceptance. Understanding is exploring the human psyche. If we want to put an end to violence, we need to have the sort of conversation I had with the teenage suicide bomber.

I hate the tribal hatred thesis - in Yugoslavia and Rwanda and places like that they kill each other because that's just what people do there. I think it's profoundly ignorant. I was astonished when Samuel Huntington wrote his famous clash of civilizations essay in response to the Yugoslavian war. I was on the streets in Sarajevo and every other person I met came from a mixed marriage. And here is Professor Huntington from Harvard writing this is a clash of civilizations. That was absurd.
