cognitive Tom Regan
Tom Regan, professor emeritus of philosophy at North Carolina State University, argues in The Case for Animal Rights (1983) that nonhuman animals are what he calls "subjects-of-a-life", and as such are bearers of rights. He writes that, because the moral rights of humans are based on their possession of certain cognitive abilities, and because these abilities are also possessed by at least some nonhuman animals, such animals must have the same moral rights as humans. Although only humans act as moral agents, both marginal-case humans, such as infants, and at least some nonhumans must have the status of "moral patients".
