Andrea Natan Feltrin

I graduated in Philosophy and Philosophical Sciences from the University of Milan, and later specialized in Environmental Management Conservation at the University of Stirling, conducting research on the reintroduction of beavers in the Scottish Highlands. With prior experience in rewilding initiatives across Europe, including management of eucalyptus in Spain and cohabitation with large carnivores in Finland, I am currently pursuing my PhD within the framework of environmental ethics and critical animal studies. My areas of research encompass rewilding, multispecies justice, human overpopulation, inter-species coexistence, and the philosophy of polyamory.

Lance Gracy

Job Titles:
  • Teaching Fellow
Lance Gracy is a Teaching Fellow and Doctoral Candidate in the Department of Philosophy and Religion at the University of North Texas. His dissertation is an exegesis of wisdom in St. Bonaventure's Collationes in Hexaëmeron. In exegeting/articulating this last great work of the "second-founder" of the Franciscan Order, Lance's dissertation conveys the "return to the wisdom of metaphysics and religion" as not only a return to exhortative and propaedeutical reading and instruction, sound doctrine, (re)conciliation, and so on, but also as something importantly related to the environment and ecology. Thus, one implication is that through a return to the wisdom of metaphysics of religion, one properly reorients themselves to the time, status, nature, being(s), etc. of creation. Lance has also been involved with various organizations in support of an environmental focus, to include the St. Kateri Tekakwitha Conservation Center, the St. Basil Institute for the Theology of Creation, and American Pilgrims on the Camino.
