In South Africa, we could not have achieved our freedom and just peace without the help of people around the world, who through the use of non-violent means, such as boycotts and divestment, encouraged their governments and other corporate actors to reverse decades-long support for the Apartheid regime.

I have seen firsthand how injustice gets overlooked when the victims are powerless or vulnerable, when they have no one to speak up for them and no means of representing themselves to a higher authority. Animals are in precisely that position. Unless we are mindful of their interests and speak out loudly on their behalf, abuse and cruelty go unchallenged.

I don't often want to speak. I try to be a reasonable person and to be diplomatic, but you go to that place and you see the settlements, you see what has happened to the land that was owned by the Palestinians.

I think it is a good exercise to ask oneself, "How would I have wanted to be treated?"

When we look squarely at injustice and get involved, we actually feel less pain, not more, because we overcome the gnawing guilt and despair that festers under our numbness. We clean the wound - our own and others' - and it can finally heal.

Forgiveness is taking seriously the awfulness of what has happened when you are treated unfairly. Forgiveness is not pretending that things are other than the way they are.

As a teacher in order not to have to answer too many questions, you stretch your answers.
