self responsibility versus the commons

Is self responsibility an absolute? If each person is fully, solely and completely responsible for their own experience, when does responsibility arise for any kind of commons?  In my view, every relationship has a commons, the shared space where two friends come together to relate, to mutually support one another's evolution, to mutually care one for the other.

Is all love self love? or is there something about love that includes (requires?) an other?  Can one person in isolation lead a life of being loving without having any orientation to beings beyond one's self?

No.  Of course not.  The human commons is not just about sharing physical resources to live, such as food, water, shelter and clothing. The human commons is also about sharing ourselves with others. It is all about the shared space where relationships happen. 

There can be no human commons without mutuality, without mutual caring, mutual support and mutual trust. Self responsibility is not an absolute. Like all aspects of nature, which is to say all aspects of the living system we each belong to, we are always interdependent.  We are all dependent on the air we breath, trusting that it has enough oxygen to meet our need for oxygen. And we are all dependent on other people to be whole and independent.  Maybe this is the paradox of self responsibility:  yes, each of us is fully responsible for the self but we have a simultaneous, neverending responsibility to the commons, where human lives intersect.
