Final answer:
Judith Jarvis Thomson does not argue that all abortions are morally permissible but rather that the fetus's right to life is not absolute, illustrating her position with the violinist thought experiment.
Step-by-step explanation:
Judith Jarvis Thomson's "A Defense of Abortion" does not defend the position that all abortions are morally permissible. Instead, Thomson argues that the fetus's right to life is not absolute and that circumstances exist where abortion can be morally permissible, as demonstrated by her famous violinist thought experiment. Contrastingly, it is Mary Anne Warren who claims that because a fetus is not a person, it does not have rights, and abortion is always morally permissible. Thomson's nuanced position accounts for situations that balance the rights of the pregnant person against the rights of the fetus, and does not equate to an unrestricted liberal stance.
Judith Jarvis Thomson's "A Defense of Abortion" does not defend the liberal position on abortion that all abortions are morally permissible. In her essay, Thomson presents various thought experiments to challenge the idea that a fetus has an absolute right to life, but she does not argue that all abortions are morally permissible. Instead, she engages in a nuanced discussion about rights and personhood, considering the circumstances in which abortion may be morally justified.
