Abstract
The debate concerning abortion abounds in miraculous narratives. Judith Jarvis Thomson has contrived the most
celebrated set among related ones, to wit the “violinist analogy,” the “Good Samaritan” narrative, and the “Henry
Fonda” allegory, by virtue of which, she intends, on the one hand, to argue that women’s right to autonomy
outweighs the alleged fetus’s right to life, and on the other, to prove that no positive moral duties can be derived
towards other persons alone from the fact that a moral agent is ascribed certain rights. What this short paper
endeavors to prove is that Thomson’s argumentation by analogy is a weak one, since neither the number nor the
relevance of similarities invoked is adequate or satisfactory, while crucial parameters concerning the morality of
abortion are being totally overlooked.
