Unborn vs. Newborn: Which is Human?

[Adapted from Reaching Hearts and Minds on Abortion by Scott Klusendorf a professor of Bioethics. The SLED acronym was developed by Stephen Schwarz in The Moral Question of Abortion (Chicago: Loyola University Press, 1990) pp. 17-18.]

After some preliminary discussions...

Pro-Life: "Do you think that newborns are persons?"

Pro-Choice: "Yes, of course. Everyone does."

Pro-Life: "What are the differences between fetuses and newborns?"

Pro-Choice: "There are many, important differences."

Pro-Life: "If we look at those differences to see if they are morally relevant then we can answer the question if it’s morally permissible to kill fetuses and not kill newborns."

Pro-Choice: "Sounds reasonable."

Pro-Life: "As it turns out, unborns differ from the newborns in just four ways which I pose are not relevant to its status as a human being. Those four ways are Size, Level of Development, Environment, and Degree of Dependency. The acronym SLED is a helpful reminder of those differences."

Pro-Life: "We can see, then, that the unborn child differs from a newborn child in only four ways—size, level of development, environment, and degree of dependency—and none of those differences are good reasons for disqualifying it as fully human."

Pro-Choice: "You know, I’ve been listening to you pro-lifers for 30 years. I’ve had people shove rosary beads at me, tell me I was going to burn in hell, and even had evangelicals praying for my soul. But this is the first time I have ever heard one of you right-to-lifers explain why you believe what you believe. I guess I will have to give it some thought."
