This is the fifth volume in an ongoing project reexamining the philosophic tradition from the standpoint of the good. The ongoing project seeks to understand humanity's relation to nature in a profoundly ethical way. This volume develops an understanding in ecological terms. It does so by examining the notion of giving in relation to having, calling into question the ways in which being human, and being itself, have been understood in terms of what one must have and possess in order to live well--goods, qualities, a body, a dwelling, freedom, land, children, family, things, knowledge, power, authenticity--all forms of genitivity. Having is explored in terms of ecstasy, squander, generosity, and sustenance, then as betrayal and forgiveness. Betrayal is understood as the expressiveness of things, always promised to circulation in abundance beyond containment, use or profit: the circulation of goods and commodities together with the circulation of images, meanings, language, and writing.
