In 1999 Archbishop Tutu sat down with Bill Moyers, discussing the draining process of facing his country's past as he chaired the South African Truth and Reconciliation Commission.

Tutu explains:

What I did learn were, as with two contrary things, that one was to be overwhelmed by the depth of depravity to which we can sink. That's the one side. And that bowls you over.

But that's not the only truth that comes out because the other thing that the commission revealed is that people are incredible. People are a glorious creation; that just as much as we have the extraordinary capacity for evil, so we have a remarkable capacity for good.

When you listened to people who by rights ought to have been bristling with anger and resentment showing that magnanimity, that willingness to forgive. That's tremendous.
