Although debates about the shape and future of the built environment are usually cast in economic and political terms, they also have an irreducible ethical component that stands in need of careful examination. This paper is the report of an exploratory study in descriptive ethics carried out in Atlanta, Georgia. Archival sources and semi-structured interviews provide the basis for identifying and sorting the diverse value judgments and value conflicts that come into play in a rapidly growing metropolitan area. The goal of the project is to expand and refine a draft framework for grappling with the ethical complexity of the situations from which individuals and communities make important decisions about their surroundings. The success of the framework is to be measured by its usefulness in informing the judgment of professionals and citizens, and in facilitating a robust normative debate about the built environment

On the basis of a model of the development of scientific concepts as analogous to the “adaptive radiation” of organisms, I raise questions concerning the speculative project of many environmental philosophers, especially insofar as that project reflects on the relationship between ecology (the science) and ecologism (the worldview or ideology). This relationship is often understood in terms of anopposition to the “modern” worldview, which leads to the identification of ecology as an ally or as a foe of environmental philosophy even as ecological concepts are freely appropriated to inform speculation. I argue that ecology does not fit into the intellectual framework of such an opposition and that its concepts cannot readily be made to serve purposes outside of their specialized context without a loss of meaning. Finally, I suggest that environmental thought might do well to divest itself of its ecologistic commitments, adopting instead a skeptical approach to human-environment relations.

There are two distinct strands within modern philosophical ethics that are relevant to environmental philosophy: an empiricist strand that seeks a naturalist account of human conduct and a humanist strand rooted in a conception of transcendent human freedom. Each strand has its appeal, but each also raises both strategic and theoretical problems for environmental philosophers. Based on a reading of Kant's critical solution to the antinomy of freedom and nature, I recommend that environmental philosophers consider the possibility of a Darwinian humanism, through which moral agents are understood as both free and causally intertwined with the natural world

As a contribution to an experiential approach to environmental ethics, I seek to incorporate into the experience of place a sense of the passing of time across multiple scales. This may spur the recognition that places we are pleased to experience as stable backdrops for our projects may be transitory, in the short or long term, with important consequences for ethical deliberation. The occasion for this essay is a visit to the Karori Sanctuary in Wellington, New Zealand, the site of an ambitious restoration project set against the backdrop of ongoing biogeographic upheaval.
