Empathy

'I sat in Alyth Gardens synagogue in Golders Green in north London last year. Two men went up on the stage. The first one spoke: "I am Ahmed, and I am a Palestinian. My son died in the Intifada, killed by an Israeli bullet. I come to wish you all Shabbat Shalom."

Then the other man spoke: "I am Moishe, and I am an Israeli. My son also died in the Intifada, killed by a homemade petrol bomb thrown by a Palestinian teenager. I come to wish you all Salaam Alaikum."

I was shocked: here were two fathers, from different sides of the political divide, united by their grief and now embracing each other's language. How had they met? Moishe had taken up the opportunity offered by a charity called The Parents Circle for Israelis and Palestinians to make free phone calls directly into each other's homes, to express their empathy to bereaved parents on the other side of the barbed-wire fence. Ahmed described how he had been at home in Gaza one day when the phone rang. It was Moishe, at that time a stranger in Jerusalem, who had taken that brave first step. They both openly wept down the phone. Neither had ever met or even spoken to someone from the other community, but both told the other they knew what the other was going through.

Empathy is like a universal solvent. Any problem immersed in empathy becomes soluble. It is effective as a way of anticipating and resolving interpersonal problems, whether this is a marital conflict, an international conflict, a problem at work, difficulties in a friendship, political deadlocks, a family dispute, or a problem with the neighbour. Unlike the arms industry that costs trillions of dollars to maintain, or the prison service and legal system that cost millions of dollars to keep oiled, empathy is free. And, unlike religion, empathy cannot, by definition, oppress anyone.'
