Ethics Abortion Essay
Here, the people-seeds flying through the window represent conception, despite the precautionary mesh screen, which functions as contraception.
The woman does not want a people-seed to root itself in her house, and so she even takes the measure to protect herself with the best mesh screens, and then voluntarily opens the windows.
She gives as an example a hypothetical woman who seeks a late-term abortion "just to avoid the nuisance of postponing a trip abroad" and declares this to be "positively indecent".
Thomson also explicitly rejects the claim that pregnant women have a right to kill their offspring.
If we say that no one may help the mother obtain an abortion, we fail to acknowledge the mother's right over her body (or property).
Thomson says that we are not personally obligated to help the mother but this does not rule out the possibility that someone else may act.
Granting for the sake of argument that the fetus has a right to life, Thomson uses thought experiments to argue that the fetus's right to life does not trump the pregnant woman's right to have jurisdiction over her body, and that induced abortion is therefore not morally impermissible.
As Thomson reminds, the house belongs to the mother; similarly, the body which holds a fetus also belongs to the mother.
Again, suppose it were like this: people-seeds drift about in the air like pollen, and if you open your windows, one may drift in and take root in your carpets or upholstery.
You don't want children, so you fix up your windows with fine mesh screens, the very best you can buy.
As can happen, however, and on very, very rare occasions does happen, one of the screens is defective; and a seed drifts in and takes root.
