India has recently banned holding dolphins captive and especially "dolphin shows." Their reasoning?
“Whereas cetaceans in general are highly intelligent and sensitive, and various scientists who have researched dolphin behavior have suggested that the unusually high intelligence; as compared to other animals means that dolphin should be seen as ‘non-human persons’ and as such should have their own specific rights and is morally unacceptable to keep them captive for entertainment purpose.”
What, then, gives personhood? What are the legal, moral, and ethical implications of conferring personhood on non-human persons?
What about our spiritual and religious point-of-view? If we include non-human persons in our soteriology (doctrines of how we are "saved"), does that change our soteriology? Does it change our understanding of the divine? Of each other?
