Observes that the abortion debate is intractable since both sides have such different methodological assumptions
Give an example of the differences the opposing sides have.
Pro-life: assumes fetus is a person from the moment of conception; concludes abortion is immoral because the fetus has a right to life Pro-choice: presupposes psychological criteria for personhood that the fetus does not possess, fetus is thus not a person and has no rights
