Level of development: The unborn is also less developed than a born human being. How does this fact, though, disqualify the unborn from personhood? A four year-old girl can’t bear children because her reproductive system is less developed than a fourteen year-old girl. That doesn’t disqualify her from personhood. She is still as equally valuable as a child-bearing teen. The unborn is also less developed than the four year-old. Therefore, we can’t disqualify her from personhood for the same reason we can’t disqualify the four year-old. Both are merely less developed than older human beings.
