For the purposes of discussion, I had an idea to use an analogy of a comatose patient to explore whether fetuses count as actual human beings or just potential human beings. Granted, the idea is kind of rough so I just wanted to see how it would work in practice.
If you answered that the comatose patient should be kept alive, then presumably you should answer that a fetus should be kept alive as well. As a comatose patient who is amnesiac and without attachment, John Doe is basically like a fetus in the following ways: (i) he has approximately the same limited cognitive functioning more or less (ii) he has no attachments to anyone, (iii) he has no memory of experiences (iv) and if someone killed him, he presumably would not feel much pain.
Perhaps the real issue with abortion are the costs that are imposed on the pregnant woman. If these costs are dealt with, perhaps the issue of aborting fetuses may not be necessary. What if people were legally required to treat pregnant women no different from other women? That is, what if a person could be prosecuted for child abuse if he/she discriminated against a pregnant woman, because it would start a chain of events that would lead to abortion?
What do you think?
