Interesting, I'll have to read this more thoroughly when I have time. I used to call my ethical system relational ethics, and in some respects it still is. However, I have since expanded it to be a form of "institutionalism," which is a perspective on economics and maybe even ontology (a form of social constructivism or "structuralism"). I cover it in summary on my ethics overview. The relational aspect is there, but it's under a broader philosophical umbrella to give it more substance. I call it a quasi-relativism that fits the naturalist metaphysical view underlying it through a philosophy of mind and society which coheres with an institutionalist or social constructivist (i.e., structuralist) perspective.
