What is the only difference between abortion and unjustified killing the short distance of the birth canal?
Stephen Swartz uses the acronym SLED to show there are only four differences between a preborn child and a newborn: size, level of development, environment, degree of dependency.
Size: Yes, embryos are smaller than newborns and adults, but why is that relevant? Men are generally taller than women, but physical size doesn’t equal value.
Level of Development: True, embryos and fetuses are less developed than you and me. Should older children have more rights than their younger siblings? Some people say self-awareness makes one human. If that were true newborns would not qualify as human beings.
Environment: Where you are has no bearing on who you are. Does your value change when you cross the street or roll over in bed? Location cannot change the essential nature of the preborn
from non-human to human. If the preborn were not already human, merely changing their location, moving them eight inches down the birth canal, can’t make them so.
Degree of Dependency: If viability makes us valuable human beings, then all who depend upon insulin or kidney medication are not valuable. Conjoined twins who share blood type and bodily systems would also have no right to life. Although humans differ greatly with respect to talents, accomplishments, and degrees of development, they are equally valuable because they share a common nature.
