Re-defining embryos and fetuses as persons under the law has been a long-term aim of hard-line anti-abortion advocates. Since the repeal of Roe v Wade, these efforts have stepped up in the US, with some success. This brings to back to the fore a central dispute in abortion ethics: is abortion still morally permissible even if the embryo is a person in the full rights-holding sense? Here is a related but distinct question: should abortion be legally permissible even if the embryo is a person? In this talk, I trace four key arguments in favour of the claim that embryonic and foetal personhood is compatible with the moral and legal permissibility of abortion in almost all instances: 1. The Good Samaritan Argument, 2. The Justified Homicide Argument, 3. The Justified Toleration Argument, and 4. The Back-Street Abortion Argument. I underscore the pitfalls in each argument, and sketch what this means for the relevance of the personhood or moral status question to abortion ethics.
