presumably you mean the African philosophy, rather than the Operating System?

As I understand it, a simple definition would be
I am what I am, because you are what you are, and we are all connected

anyway, it basically boils down to being part of a tight-nit group, and group dynamics

if you advance the group as a whole, a by-product is you advance all the individuals in the group, including yourself
One improvement shared by many is more efficient than simply improving yourself, or someone else alone
