Abstract

“Africans believe in something that is difficult to render in English. We call it ubuntu or botho. It means the essence of being human. You know when it is there and when it is absent. It speaks about humanness, gentleness, hospitality, putting yourself out on behalf of others, being vulnerable. It embraces compassion and roughness. It recognizes that my humanity is bound up in yours, for we can only be human together” (Desmond Tutu)
