Just a suggestion here: see http://www.biocosm.org/
Perhaps another time, we can explore the mathematics of morals in game theory and how systems "learn" (see item on "The Evolution of Cooperation" by Robert Axelrod: http://en.wikipedia.org/wiki/The_Evolution_of_Cooperation). Key point being: intelligence is an inherent property of existence, making universe itself intelligble and producing evolution of higher order complex mind. Moreover, "Prisoners Dilemma" probably operates at quantum levels.
This is a deeper inquiry into the Cosmos that Bucky Fuller explored in works like Synergetics, and explains tendencies like tensegrity to manifest in Nature. Gardner's proposition of Biocosm, that "Intelligent life is the architect of the universe," takes this to a profound level of science. The implications for a discipline of sustainability, however, build on "learning" as a direct expression of inherent properties of existence itself. Our "intelligence" can be said to be seeking to employ its capacity to achieve sustainability as a direct manifestation of reality itself. Some might call this "God," but Nature really is operating through sentient beings who simply manifest the essential reality of being. This is not God of the Master Plan sort, because it is existence that compels us to use our creative intelligence to invent sustainability.
Existentially, there is "No Exit." "Waiting for GODOT" won't get us there. We must engage directly ourselves, risking the absurdity of our ventures.
Existence = manifestation x creative consciousness.
