Abstract

Approximately 50 years have passed since Judith Jarvis Thomson wrote A Defense of Abortion (1971). Her article has significantly shaped the philosophical literature on abortion. In this paper, I will summarize some of the interesting and important work done on the topic since Thomson's article. I will highlight Thomson as a defender of the claim that abortion is morally permissible and Don Marquis as an influential opponent of that claim. I will start by articulating Thomson's case, focusing on the violinist analogy. I will underscore key questions, concepts, and objections the analogy raises. I will then examine briefly how philosophers have addressed some of these issues. Next, I will outline Marquis’ work, provide a similar commentary on it, and discuss some of its main responses. I will then survey other philosophers who have addressed abortion beyond the scope of providing specific replies to Thomson or Marquis. I will close by highlighting significant points of agreement and disagreement in the literature, as well as crucial gaps in the current research. The paper is not an attempt to address every work on the topic over the last five decades, nor is it aimed at taking a position on the moral permissibility of abortion. My goal is to provide an overview of the dialectic.
