No, i’m not going to discuss this Ubuntu, but rather what is the philosophy of Ubuntu. And forgive my laziness, because my search come only from wikipedia. Archbishop Desmond Tutu defined ubuntu as :

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.

It’s the opposite of envy and jealousy. Chris Abani said in his video :

It’s ubuntu, the only way for me to be human is for you to reflect my humanity back at me.

So, Ubuntu is basically how you can improve the humanity of your community and other people. Nelson Mandela said it best :

A traveller through a country would stop at a village and he didn’t have to ask for food or for water. Once he stops, the people give him food, entertain him. That is one aspect of Ubuntu but it will have various aspects. Ubuntu does not mean that people should not address themselves. The question therefore is: Are you going to do so in order to enable the community around you to be able to improve?

Examples? Well, a simple act of kindness to other people really covers it all.
