A Defense of Abortion
"A Defense of Abortion" is a moral philosophy paper by Judith Jarvis Thomson first published in 1971. Granting for the sake of argument that the fetus has a right to life, Thomson uses thought experiments to argue that the fetus' right to life does not trump the pregnant woman's right to control her own body and its life-support functions, and that induced abortion is therefore not morally impermissible. Her argument has many critics on both sides of the abortion debate, yet continues to receive defense. Thomson's imaginative examples and controversial conclusions have made "A Defense of Abortion" perhaps "the most widely reprinted essay in all of contemporary philosophy".
Overview of the essay
The Violinist
In "A Defense of Abortion", Thomson grants for the sake of argument that the fetus has a right to life, but defends the permissibility of abortion by appeal to a thought experiment:
Thomson takes it that you may now permissibly unplug yourself from the violinist even though this will cause his death: the right to life, Thomson says, does not include the right to use another person's body, and so by unplugging the violinist you do not violate his right to life but merely deprive him of something—the use of your body—to which he has no right. "[I]f you do allow him to go on using your kidneys, this is a kindness on your part, and not something he can claim from you as his due."
