Abstract
Martin Rhonheimer has written extensively on disputed issues in medical ethics: the use of condoms to prevent HIV, contraception, masturbation to provide semen for analysis, and at length on “vital conflicts” in medical ethics that arise in a pregnancy in which the lives of both the mother and the child are seriously threatened. If nothing is done, both will die, but if a medical intervention is performed, the child will die but the mother has a chance of living. After offering his interpretation of relevant magisterial documents on the difference between “direct” and “indirect” killing and of St. Thomas's teaching on the lawfulness of killing in self-defense and the principle of double effect, Rhonheimer proposes to solve conflicts of this kind by an ethical analysis based on what he calls a “virtue-based ethics” concerned with rendering justice to both mother and child. Using this approach he justifies craniotomy, salpingectomy, and salpingo(s)tomy as morally permissible ways of saving the mother's life without doing any injustice while rejecting use of the drug methotrexate to end a tubal pregnancy. His analysis can be seriously challenged as rooted in a misinterpretation of key magisterial documents and for failing to consider the principle of double effect revised to bring it into harmony with Aquinas's teaching on the distinction between killing as intended and as the unintended although foreseen effect of an act of legitimate self-defense.
