I should perhaps stop to say explicitly that I am not claiming that people have a right to do anything whatever to save their lives. I think, rather, that there are drastic limits to the right of self-defense. If someone threatens you with death unless you torture someone else to death, I think you have not the right, even to save your life, to do so. But the case under consideration here is very different. In our case there are only two people involved, one whose life is threatened, and one who threatens it. Both are innocent: the one who is threatened is not threatened because of any fault, the one who threat- ens does not threaten because of any fault. For this reason we may feel that we bystanders cannot intervene. But the person threatened can.
In sum, a woman surely can defend her life against the threat to it posed by the unborn child, even if doing so involves its death. And this shows not merely that the theses in (1) through (4) are false; it shows also that the ex- treme view of abortion is false, and so we need not canvass any other possi- ble ways of arriving at it from the argument I mentioned at the outset.
The extreme view could of course be weakened to say that while abortion is permissible to save the mother’s life, it may not be performed by a third party, but only by the mother herself. But this cannot be right either. For what we have to keep in mind is that the mother and the unborn child are not like two tenants in a small house which has, by an unfortunate mis- take, been rented to both: the mother owns the house. The fact that she does adds to the offensiveness of deducing that the mother can do nothing from the supposition that third parties can do nothing. But it does more than this: it casts a bright light on the supposition that third parties can do nothing. Certainly it lets us see that a third party who says “I cannot choose between you” is fooling himself if he thinks this is impartiality. If Jones has found and fastened on a certain coat, which he needs to keep him from freezing, but which Smith also needs to keep him from freezing, then it is not impartiality that says “I cannot choose between you” when Smith owns the coat. Women have said again and again “This is my body!” and they have reason to feel angry, reason to feel that it has been like shouting into the wind. Smith, after all, is hardly likely to bless us if we say to him, “Of course it’s your coat; any- body would grant that it is. But no one may choose between you and Jones who is to have it.”
