His main argument concerns the existence of very rare exceptions where abortion is not morally wrong. He initially began his argument by showing the various points of the intellectual battles between pro-choice people and pro-life people.

Topics are not successfully emphasized because they do not meet in the middle because they are too broad or too narrow. Marquis talks about how anti-abortionists would claim this because a fetus resembles a baby at some point and how they find enough information to support their pro-life position.
