This paper aims to construct an account of valuing nature that takes into consideration its interest and asserts its representation within human political institutions. Value, a human concept, is fundamental to human relations. This paper seeks to apply a conception of value to nature that will serve to justify and guide our actions and interactions with it. Our condition is that of dependence and being within nature, conceived holistically as ecosystem or biosphere. As such, the whole of nature can be interpreted as a system of purposes—a Kantian natural purpose. Conceived in this manner, nature invites us to consider the possibility of seeing it as a recipient of moral action. As natural purpose, we are also asked to agree with the assertion that it acts autonomously, and that its action ends with the life-support system that sustains us. All these give us a conception of nature and of its interest as potentially belonging within societal institution. They allow us to ascribe to nature moral value and political agency. Thus, we conclude with two images that appear paradoxical but that would make final sense: us in nature and nature among us.
