…It is the essence of being human. It speaks of the fact that my humanity is caught up and is inextricably bound up in yours. I am human because I belong. It speaks about wholeness, it speaks about compassion. A person with ubuntu is welcoming, hospitable, warm and generous, willing to share. Such people are open and available to others, willing to be vulnerable, affirming of others, do not feel threatened that others are able and good, for they have a proper self-assurance that comes from knowing that they belong in a greater whole. They know that they are diminished when others are humiliated, diminished when others are oppressed, diminished when others are treated as if they were less than who they are. The quality of ubuntu gives people resilience, enabling them to survive and emerge still human despite all efforts to dehumanise them.

Ubuntu is very difficult to render into a Western language. When we want to give high praise to someone we say, "Yu u nobuntu"; "Hey, so-and-so has ubuntu." Then you are generous, you are hospitable, you are friendly and caring and compassionate. You share what you have. It is to say, "My humanity is caught up, is inextricably bound up, in what is yours." . . . We say, "A person is a person through other persons." . . . A person with ubuntu is open and available to others, affirming of others, does not feel threatened that others are able and good, for he or she has a proper self-assurance that comes from knowing that he or she belongs in a greater whole and is diminished when others are humiliated or diminished, when others are tortured or oppressed.... To forgive is not just to be altruistic. It is the best form of self-interest. What dehumanizes you inexorably dehumanizes me. [Forgiveness] gives people resilience, enabling them to survive and emerge still human despite all efforts to dehumanize them.

Archbishop Desmond Tutu, from "No Future Without Forgiveness"
