Lead
Judith Jarvis Thomson (October 4, 1929 –November 20, 2020) was an American philosopher who studied and worked on ethics and metaphysics. Her work ranges across a variety of fields, but she is most known for her work regarding the thought experiment titled the trolley problem and her writings on abortion. She is credited with naming, developing, and initiating the extensive literature on the trolley problem first posed by Philippa Foot which has found a wide range use since. Thomson also published a paper titled "A Defense of Abortion", which makes the argument that the procedure is morally permissible even if it is assumed that a fetus is a person with a right to life. She was elected a member of the American Philosophical Society in 2019.

Article body
Thomson's main areas of research were moral philosophy and metaphysics. In moral philosophy she made significant contributions to meta-ethics, normative ethics, and applied ethics.

"A Defense of Abortion" (1971) introduced one thought experiment for which Thomson is especially well known. Published in 1971, Thomson’s work on abortion is historically connected to and located just prior to the court case of Roe v Wade. The paper asks the reader to imagine that her circulatory system has, without her consent, been connected to that of a famous violinist whose life she must sustain for nine months. The hypothetical posed by Thomson notably redirects philosophical attention from the rights of the fetus to those of the pregnant woman. Specifically, her argument accepts that a fetus is a person, moving past any discussion which revolved around that topic. Instead, Thomson claims that the bodily autonomy of the woman supersedes any rights of the fetus. This argument has been widely discussed since, such that it is accepted in some pro-life circles to have changed the way in which abortion is debated.

In regards to ethical theories, Thomson was opposed to consequentialist, hedonist, and subjectivist perspectives. Her work relied on specific elements of deontological argumentation.

In metaphysics, Thomson focused on questions regarding the relationship between actions and events, and between time and physical parts.

She also made significant contributions on the topic of privacy.
