This famous monumental defense of abortion by Judith Jarvis Thomson predates the Roe v. Wade decision by almost two years. In this article submitted to Philosophy & Public Affairs (Vol. 1, no. 1 [Fall 1971]), Thomson argues by various analogies that the fetus should not be legally defensible as having an inalienable right to life. Her most famous argument from analogy is the “violinist argument” comparing an unwanted pregnancy to a forced medical attachment to a violinist with a kidney disease. The attachment is supposed to sustain the violinist life. The full article without commentary can be found A Defense of Abortion (Without Commentary).Thomson.
