Darr notes that some threatened species have survived on this planet for hundreds of millions of years. “There’s something deeply troubling,” he says, ”about the thought that species that have been on this Earth for this long are potentially being wiped out by us.”
Ryan Darr joined the YDS faculty in the Fall of 2024. In addition to his work on multispecies justice, he pursues research on issues including environmental ethics, structural injustice, ethical theory, and the history of religious and philosophical ethics. He is currently writing a book that defends an account of environmental and multispecies justice as a framework for thinking ethically about the crisis of biodiversity loss and mass extinction. His first book, The Best Effect: Theology and the Origins of Consequentialism, was published by the University of Chicago Press in 2023.
The professor objects to Christian theology that gives greater value to humans over other creatures, arguing that all creatures reflect God in different ways. “I think it’s hubris to think that we can tell which creatures reflect God more or less than any other creatures,” he says.
The YDS Quadcast is hosted by Emily Judd ‘19 M.A.R., who is Senior Communications Specialist at the Higher Committee of Human Fraternity, an international humanitarian organization. She previously worked as a journalist in the Middle East.
