In this paper, I outline valuable insights that current theorists working in urban environmental ethics can gain from the analysis of nineteenth century urban contexts. Specifically, I argue that an analysis of urban areas during this time reveals two sets of competing metaphysical commitments that, when accepted, shift both the design of urban environments and our relationship with the natural world in these contexts. While one set of metaphysical commitments could help inform current projects in urban environmental ethics, the second (...) “de-animalized” or “cleansed” commitments that influenced the structure of post-nineteenth century urban areas could potentially harm projects in urban environmental ethics. Thus we need to be particularly careful when choosing a metaphysical base for our current urban environmental ethics, as, depending on your specific project, implicitly accepting certain commitments could inadvertently work against the overall goals of the project.
