Le  : Discours-hommage du président des États-Unis Barack Obama pour les funérailles de Nelson Mandela :

« Finally, Mandela understood the ties that bind the human spirit. There is a word in South Africa—Ubuntu—that describes his greatest gift: his recognition that we are all bound together in ways that can be invisible to the eye; that there is a oneness to humanity; that we achieve ourselves by sharing ourselves with others, and caring for those around us. We can never know how much of this was innate in him, or how much of was shap—and burnished in a dark, solitary cell. But we remember the gestures, large and small—introducing his jailors as honored guests at his inauguration; taking the pitch in a Springbok uniform; turning his family’s heartbreak into a call to confront HIV/AIDS—that revealed the depth of his empathy and understanding. He not only embodied Ubuntu; he taught millions to find that truth within themselves. It took a man like Madiba to free not just the prisoner, but the jailor as well; to show that you must trust others so that they may trust you; to teach that reconciliation is not a matter of ignoring a cruel past, but a means of confronting it with inclusion, generosity and truth. He changed laws, but also hearts. »
