Will Humanity Ever Fully Include the Nonhuman World in Its Moral Circle?

Excerpt from The Moral Circle (2025)

Against Human Exceptionalism

Aeon (2022)

This essay examines and challenges human exceptionalism, the widespread belief that human lives carry more ethical weight than nonhuman lives. Beginning with xenotransplantation, where pigs are used as organ donors, it traces how similar reasoning underlies broader practices—factory farming, wildlife exploitation, and environmental destruction—that impose vast harms on nonhumans. Drawing on capacities-based and relationship-based arguments, the essay shows that even if humans sometimes have stronger claims, this does not justify the scale or severity of current exploitation. Instead, ethical consistency suggests that we should prioritize nonhuman animals far more than we do, and perhaps even over ourselves.

The Case for Nonhuman Personhood

Harvard University School of Law (2019)

Under current U.S. law, one is either a “person” or a “thing.” If you are a person, you have the capacity for rights. If you are a thing, you do not. And unfortunately, all nonhuman animals are currently considered things under U.S. law. In this talk, I present the case for nonhuman personhood. I consider the four main conceptions of personhood that U.S. courts have cited: a species conception, a social contract conception, a community conception, and a capacities conception. I conclude that if we insist on classifying every being as either a person or a thing, and if we want to be both consistent and inclusive, then we have no choice but to accept that nonhumans can be persons too. This talk is based on an amicus brief that a group of 17 philosophers, including me, submitted to the New York Court of Appeals in Spring 2018 in support of the Nonhuman Rights Project, and a book that 13 of these philosophers, including me, published in Fall 2018.

In this episode, host Luisa Rodriguez speaks with Jeff Sebo, director of the NYU Center for Mind, Ethics, and Policy, about how to prepare for a future with digital minds. They discuss the non-negligible chance that AI systems could be sentient by 2030 and what moral, legal, and political status such systems might deserve, including questions of personhood and citizenship. Topics include rights for AI copies, responsibilities in connected minds, population ethics, and the challenges of building AI welfare as a field. Sebo also reflects on the role of improv comedy in ethics and effective altruism.
