Protecting Persons from Animal Bites: the Case for the Ontological Significance of Persons

Eric Olson criticizes Lynne Baker’s constitution account of persons on the grounds that personhood couldn’t be ontologically significant as nothing new comes into existence with the acquisition of thought. He claims that for something coming to function as a thinker is no more ontologically significant than something coming to function as a locomotor when a motor is added to it. He levels two related charges that there’s no principled answer about when and where constitution takes place rather than an already existing object just acquiring new properties. I’ll argue that none of these objections are problems for understanding person to be a substantial kind.
