The Violinist

Bodily autonomy and the right to life

Judith Jarvis Thomson · 1971 · Ethics

First published: J. J. Thomson, "A Defense of Abortion", *Philosophy and Public Affairs* 1 (1971): 47–66.

You wake up surgically attached to an unconscious violinist who will die unless you remain plugged in for nine months. Must you stay?

Thomson grants, for argument's sake, that the foetus is a person with a right to life, and asks whether this entails that abortion is impermissible. The violinist scenario shows that a right to life does not entail a right to use another's body without consent. The argument restructured the abortion debate, shifting it from the personhood of the foetus to the scope and limits of bodily rights, and remains the canonical analytic-philosophy intervention.

Formulation

You are kidnapped and surgically connected to a famous violinist whose survival requires your kidneys for nine months. Disconnecting kills him. Is unplugging him permissible?

Responses — How Schools Engage

Affirms / takes the bait 1

Kantian Transcendental Idealism

A Kantian can grant the conclusion via the formula of humanity: no one may be used as mere means, even to save a life — but the application to pregnancy is contested among Kantians.

Denies / rejects the premise 2

Catholic/Thomistic

Natural law: bodily union is not strictly analogous to forced surgical attachment; the duties of pregnancy follow from the natural goods at stake, not from an opt-in consent model.

Reformed / Calvinist Theology

The right-to-life of the unborn is treated as a divine command, not as a consequence of bodily-rights reasoning; the violinist analogy is rejected on theological grounds.

Reframes the question 3

Naturalism

Compatibilist secular ethics: rights and consent structures matter; the analogy is partial but illuminating in shifting attention to bodily-use claims rather than personhood alone.

Pragmatism

A useful thought experiment for surfacing inarticulated commitments; the practical application requires institutional and contextual reasoning the analogy alone cannot supply.

Existentialism

Authentic moral choice resists the stipulative cleanness of the scenario; the lived situation always carries more freight than the thought experiment's setup.
