The fact that humanity's relationship to nature has gone awry is rarely disputed, but the proposed cures are manifold. How should humans value the non-human world? Do humans have ethical duties to entities other than fellow humans? This course investigates a variety of proposed answers that claim to better situate humans with respect to nature. Such systems include variations on anthropocentrism, including a number of e-centric cousins (ecocentrism, biocentrism, zoocentrism, etc.) as well as movements such as deep ecology and ecofeminism. Current questions and controversies will be used to highlight the alternative visions that these various philosophies offer. Also considered will be the components of personal and communal ethics that lead to changes in praxis.
