Abortion arguments that emphasize the moral status of the fetus are concerned with a broad range of ethical issues. They ask such questions as: Is the fetus a human being? A person? Alive? Let us for the moment focus not on these terms and what they might mean, but on an even more fundamental question, namely, what kind of value or moral status does the developing fetus have? Does it have a different moral status in various stages of development? If so, when does the status change, and why? (Further questions may include how to weigh its value or rights in comparison to other values or the rights of others.) At bottom, these questions point toward the ontological and moral status of the fetus.
