humanity and relationships

Just found this quote from a Vanity Fair interview b/w Brad Pitt & Desmond Tutu. I found it interesting how it connects to how we're made in God's image and how we're created in such a relational way. God is 3 in 1 (Christian concept of the Trinity) - exists in relationship. We are human and are truly human within relationship not isolation:

Brad Pitt: What is this concept of ubuntu I keep reading about?
Tutu: "Ubuntu is the essence of being human [...] we say a person is a person through other persons. You can't be a human in isolation. You are human only in relationships. [...] So we say that 'I need you to be all of who you are in order for me to be all that I am.' Because no human being is totally self-sufficient. In fact, a self-sufficient human being is subhuman." [...] If you want to be human, we are not going to be able to be human in isolation. It will be that we are human together."

Thoughts?
