Abstract

The existence of nonhuman persons would fly in the face of everything our species has believed about its uniqueness for thousands of years. If an “animal” like a dolphin actually has all of the traits of a “person”, that would call for as fundamental, dramatic and unsettling a shift in how we see ourselves as abandoning a geocentric view of the heavens did. In the same way that Earth no longer occupied the centre of the universe, neither would humans. It would also call for a shift in how humans treat dolphins – and, very likely, many other nonhumans.
