A Defense of Abortion is a moral philosophy essay by Judith Jarvis Thomson first published in Philosophy & Public Affairs in 1971. Granting for the sake of argument that the fetus has a right to life, Thomson uses thought experiments to argue that the right to life does not include, entail, or imply the right to use someone else's body to survive and that induced abortion is therefore morally permissible. Thomson's argument has critics on both sides of the abortion debate, [1] [2] but it continues to receive defense. [3] Despite criticism, "A Defense of Abortion" remains highly influential. [4]
In "A Defense of Abortion", Thomson grants for the sake of argument that the fetus has a right to life but defends the permissibility of abortion by appealing to a thought experiment. She writes:
You wake up in the morning and find yourself back to back in bed with an unconscious violinist. A famous unconscious violinist. He has been found to have a fatal kidney ailment, and the Society of Music Lovers has canvassed all the available medical records and found that you alone have the right blood type to help. They have therefore kidnapped you, and last night the violinist's circulatory system was plugged into yours, so that your kidneys can be used to extract poisons from his blood as well as your own. [If he is unplugged from you now, he will die; but] in nine months he will have recovered from his ailment, and can safely be unplugged from you. [5]
Thomson argues that one can permissibly unplug oneself from the violinist even though this will cause his death; this is due to limits on the right to life, which does not include the right to use another person's body, and so by unplugging the violinist one does not violate his right to life but merely deprives him of something – the use of someone else's body – to which he has no right. She argues: "[I]f you do allow him to go on using your kidneys, this is a kindness on your part, and not something he can claim from you as his due." [6] For the same reason, Thomson says that abortion does not violate the fetus's legitimate right to life but merely deprives the fetus of something – the non-consensual use of the pregnant woman's body and life-supporting functions – to which it has no right. Thus, by choosing to terminate her pregnancy, Thomson concludes that a pregnant woman does not normally violate the fetus's right to life but merely withdraws its use of her own body, which usually causes the fetus to die. [7]
Thomson criticizes the common method of deducing a woman's right to abort from the permissibility of a third party committing the abortion. In most instances, a woman's right to abortion may hinge on the doctor's willingness to perform it. If the doctor refuses, then the pregnant woman is denied her right. To base the pregnant woman's right on the accordance or refusal of a doctor, she argues that it is to ignore the pregnant woman's full personhood and subsequently her right to her own body. Thomson presents the hypothetical example of the expanding child. She writes:
Suppose you find yourself trapped in a tiny house with a growing child. I mean a very tiny house and a rapidly growing child – you are already up against the wall of the house and in a few minutes you'll be crushed to death. The child on the other hand won't be crushed to death; if nothing is done to stop him from growing he'll be hurt, but in the end, he'll simply burst open the house and walk out a free man. [8]
Thomson concedes that a third party cannot make the choice to kill either the person being crushed or the child but argues that this does not mean the person being crushed cannot act in self-defense and attack the child to save his or her own life. To liken this to pregnancy, the mother can be thought to be the person inside the house and the fetus to be the growing child. In such a case, the mothers's life is being threatened, and the fetus is the one who threatens it. Because for no reason should the pregnant woman's life be threatened and also for no reason is the fetus threatening it, both are innocent and thus no third party can intervene. Thomson asserts that the person threatened can intervene, by which justification a mother can rightfully abort. [9] Returning to the expanding child example, she argues:
For what we have to keep in mind is that the mother and the unborn child are not like two tenants in a small house, which has, by unfortunate mistake, been rented to both: the mother owns [italics in original] the house. The fact that she does adds to the offensiveness of deducing that the mother can do nothing from the supposition that third parties can do nothing. But it does more than this: it casts a bright light on the supposition that third parties can do nothing. [10]
If one says that no one may help the mother obtain an abortion, this is a failure to acknowledge her right over her own body or property. Thomson says that one is not personally obligated to help the pregnant woman, although this does not rule out the possibility that someone else may act. Thomson reminds that the house belongs to the pregnant woman; similarly, the body which holds a fetus also belongs to her. [11]
To illustrate an example of pregnancy due to voluntary intercourse, Thomson presents the people-seeds situation. She writes:
Again, suppose it were like this: people-seeds drift about in the air like pollen, and if you open your windows, one may drift in and take root in your carpets or upholstery. You don't want children, so you fix up your windows with fine mesh screens, the very best you can buy. As can happen, however, and on very, very rare occasions does happen, one of the screens is defective; and a seed drifts in and takes root. [12]
In this example, the people-seeds flying through the window represent conception, despite the precautionary mesh screen, which functions as contraception. The woman in question does not want a people-seed to root itself in her house, and so she takes the necessary precautions and measures to protect herself with the best mesh screens and then voluntarily opens the windows. In the event that a single people-seed finds its way through the window screens, unwelcome as it may be, Thomson asks whether the simple fact that the woman knowingly risked such an occurrence when opening her window deny her the ability to rid her house of the intruder. She observes that some may argue the affirmative to this question, stating: "[A]fter all you could have lived out your life with bare floors and furniture, or with sealed windows and doors." [13] Thomson responds that in following this logic any woman could avoid pregnancy from rape by simply having a hysterectomy – an extreme procedure simply to safeguard against such a possibility. Thomson concludes that although there may be times when the fetus has a right to the pregnant woman's body, it does not have a right to her body in most cases. This analogy raises the issue of whether all abortions are unjust killing. [13]
Thomson does not support abortion in all circumstances, and she gives as an example a hypothetical woman who seeks a late termination of pregnancy "just to avoid the nuisance of postponing a trip abroad", and declares this to be "positively indecent". [14] Thomson also explicitly rejects the claim that pregnant women have a right to kill their offspring. She argues for the right of the pregnant woman to stop being pregnant even if this results in the death of the offspring but not for the right to ensure that the offspring is dead. For example, if a late-term abortion accidentally results in the birth of a living baby, then Thomson would conclude that the mother has no right to kill the baby. [15]
By positing a moral justification for abortion even if one grants a fetal right to life, Thomson's article opened up a new avenue in the philosophical debate about the ethics of abortion. Critics of her view have formulated many objections to her argument, and defenders have responded in kind in a back and forth that continues in philosophy journals. Thomson's imaginative examples and controversial conclusions have made "A Defense of Abortion" perhaps "the most widely reprinted essay in all of contemporary philosophy". [16] Critics of Thomson's argument generally grant the permissibility of unplugging the violinist but seek to block the inference that abortion is permissible by arguing that there are morally relevant differences between the violinist scenario and typical cases of abortion. One notable exception to this general agreement is Peter Singer, who argues that, despite human intuitions, a utilitarian calculus implies that one is morally obliged to stay connected to the violinist. [17] Thomson observes that the woman's right to abortion does not include the right to directly insist upon the death of the child should the fetus happen to be viable, that is, capable of surviving outside the womb. She writes: "All the same, I agree that the desire for the child's death is not one which anybody may gratify, should it turn out to be possible to detach the child alive." [15]
The most common objection is that Thomson's violinist argument can justify abortion only in cases of rape, although Thomson uses separate analogies to argue in cases other than rape. In the violinist scenario, the pregnant woman was kidnapped; she did not consent to having the violinist plugged into her and she did nothing to cause the violinist to be plugged in, just as a woman who is pregnant due to rape did nothing to cause the pregnancy. In some cases of abortion, the pregnant woman had voluntary intercourse, and thus has either tacitly consented to allow the fetus to use her body (the tacit consent objection), [18] or else has a duty to sustain the fetus because the pregnant woman herself caused the fetus to stand in need of her body (the responsibility objection). [19] Other common objections turn on the claim that the fetus is the pregnant woman's child, whereas the violinist is a stranger (the stranger versus offspring objection), [20] or that abortion directly and intentionally kills the fetus, whereas unplugging the violinist merely lets him die of natural causes (the killing versus letting die objection). [20] Defenders of Thomson's argument reply that the alleged disanalogies between the violinist scenario and typical cases of abortion do not matter, either because the factors that critics appeal to are not genuinely morally relevant, or because those factors are morally relevant but do not apply to abortion in the way that critics have claimed. Thomson's defenders also point to her people-seeds argument as a strong analogy to typical cases of abortion. [21]
Numerous religious traditions have taken a stance on abortion but few are absolute. These stances span a broad spectrum, based on numerous teachings, deities, or religious print, and some of those views are highlighted below.
Libertarians promote individual liberty and seek to minimize the role of the state. The abortion debate is mainly within right-libertarianism between cultural liberals and social conservatives as left-libertarians generally see it as a settled issue regarding individual rights, as they support legal access to abortion as part of what they consider to be a woman's right to control her body and its functions. Religious right and intellectual conservatives have attacked such libertarians for supporting abortion rights, especially after the demise of the Soviet Union led to a greater divide in the conservative movement between libertarians and social conservatives. Libertarian conservatives claim libertarian principles such as the non-aggression principle (NAP) apply to human beings from conception and that the universal right to life applies to fetuses in the womb. Thus, some of those individuals express opposition to legal abortion. According to a 2013 survey, 5.7/10 of American Libertarians oppose making it more difficult for a woman to get an abortion.
The abortion debate is a longstanding and contentious discourse that touches on the moral, legal, medical, and religious aspects of induced abortion. In English-speaking countries, the debate most visibly polarizes around adherents of the self-described "pro-choice" and "pro-life" movements. Pro-choice supporters uphold that individuals have the right to make their own decisions about their reproductive health, and that they should have the option to end a pregnancy if they choose to do so, taking into account various factors such as the stage of fetal development, the health of the woman, and the circumstances of the conception. Pro-life advocates, on the other hand, maintain that a fetus is a human being with inherent rights that cannot be overridden by the woman's choice or circumstances, and that abortion is morally wrong in most or all cases. Both terms are considered loaded words in mainstream media, where terms such as "abortion rights" or "anti-abortion" are generally preferred.
Applied philosophy is a branch of philosophy that studies philosophical problems of practical concern. The topic covers a broad spectrum of issues in environment, medicine, science, engineering, policy, law, politics, economics and education. The term was popularised in 1982 by the founding of the Society for Applied Philosophy by Brenda Almond, and its subsequent journal publication Journal of Applied Philosophy edited by Elizabeth Brake. Methods of applied philosophy are similar to other philosophical methods including questioning, dialectic, critical discussion, rational argument, systematic presentation, thought experiments and logical argumentation.
Anti-abortion feminism is the opposition to abortion by some feminists. Anti-abortion feminists may believe that the principles behind women's rights also call them to oppose abortion on right to life grounds and that abortion hurts women more than it benefits them.
Judith Jarvis Thomson 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.

Fetal rights are the moral rights or legal rights of the human fetus under natural and civil law. The term fetal rights came into wide usage after Roe v. Wade, the 1973 landmark case that legalized abortion in the United States and was essentially overturned in 2022. The concept of fetal rights has evolved to include the issues of maternal substance use disorders, including alcohol use disorder and opioid use disorder. Most international human rights charters "clearly reject claims that human rights should attach from conception or any time before birth." While most international human rights instruments lack a universal inclusion of the fetus as a person for the purposes of human rights, the fetus is granted various rights in the constitutions and civil codes of some countries.
The genetics and abortion issue is an extension of the abortion debate and the disability rights movement. Since the advent of forms of prenatal diagnosis, such as amniocentesis and ultrasound, it has become possible to detect the presence of congenital disorders in the fetus before birth. Specifically, disability-selective abortion is the abortion of fetuses that are found to have non-fatal mental or physical defects detected through prenatal testing. Many prenatal tests are now considered routine, such as testing for Down syndrome. Women who are discovered to be carrying fetuses with disabilities are often faced with the decision of whether to abort or to prepare to parent a child with disabilities.
Living High and Letting Die: Our Illusion of Innocence is a philosophy book by Peter K. Unger, published in 1996.
Mary Anne Warren was an American writer and philosophy professor, noted for her writings on the issue of abortion and animal rights.
The philosophical aspects of the abortion debate are logical arguments that can be made either in support of or in opposition to abortion. The philosophical arguments in the abortion debate are deontological or rights-based. The view that all or almost all abortion should be illegal generally rests on the claims that (1) the existence and moral right to life of human beings begins at or near conception-fertilization; that (2) induced abortion is the deliberate and unjust killing of the embryo in violation of its right to life; and that (3) the law should prohibit unjust violations of the right to life. The view that abortion should in most or all circumstances be legal generally rests on the claims that (1) women have a right to control what happens in and to their own bodies; that (2) abortion is a just exercise of this right; and that (3) the law should not criminalize just exercises of the right to control one's own body and its life-support functions.
Pregnant patients' rights or Pregnant women's rights refers to the choices and legal rights available to a woman experiencing pregnancy or childbirth. Specifically those under medical care within a medical establishment or those under the care of a medical professional regardless of location.
In Judaism, views on abortion draw primarily upon the legal and ethical teachings of the Hebrew Bible, the Talmud, the case-by-case decisions of responsa, and other rabbinic literature. While most major Jewish religious movements discourage abortion, except to save the life of a pregnant woman, authorities differ on when and whether it is permitted in other cases.
The beginning of human personhood is the moment when a human is first recognized as a person. There are differences of opinion about the precise time when human personhood begins and the nature of that status. The issue arises in a number of fields, including science, religion, philosophy, and law, and is most acute in debates about abortion, stem cell research, reproductive rights, and fetal rights.
Muslim views on abortion are shaped by Hadith, as well as by the opinions of legal and religious scholars and commentators. The Quran does not directly address intentional abortion, leaving greater discretion to the laws of individual countries. Although opinions among Islamic scholars differ over when a pregnancy can be terminated, there are no explicit prohibitions on a woman's ability to abort under Islamic law.
The official teachings of the Catechism of the Catholic Church promulgated by Pope John Paul II in 1992 oppose all forms of abortion procedures whose direct purpose is to destroy a zygote, blastocyst, embryo or fetus, since it holds that "human life must be respected and protected absolutely from the moment of conception. From the first moment of his existence, a human being must be recognized as having the rights of a person – among which is the inviolable right of every innocent being to life". However, the Church does recognize as morally legitimate certain acts which indirectly result in the death of the fetus, as when the direct purpose is removal of a cancerous womb. Canon 1397 §2 of the 1983 Code of Canon Law imposes automatic excommunication on Latin Catholics who actually procure an abortion, if they fulfill the conditions for being subject to such a sanction. Eastern Catholics are not subject to automatic excommunication, but by canon 1450 of the Code of Canons of the Eastern Churches they are to be excommunicated by decree if found guilty of the same action, and they may be absolved of the sin only by the eparchial bishop. In addition to teaching that abortion is immoral, the Catholic Church also generally makes public statements and takes actions in opposition to its legality.
"After-Birth Abortion: Why Should the Baby Live?" is a controversial article published by Francesca Minerva and Alberto Giubilini. Available online from 2012 and published in the Journal of Medical Ethics in 2013, it argues to call child euthanasia or infanticide "after-birth abortion" and highlights similarities between abortion and euthanasia.
Evictionism is a moral theory advanced by Walter Block and Roy Whitehead on a proposed libertarian view of abortion based on property rights. This theory is built upon the earlier work of philosopher Murray Rothbard who wrote that "no being has a right to live, unbidden, as a parasite within or upon some person's body" and that therefore the woman is entitled to eject the baby from her body at any time. Evictionists view a woman's womb as her property and an unwanted fetus as a "trespasser or parasite", even while lacking the will to act. They argue that a pregnant woman has the right to evict a fetus from her body since she has no obligation to care for a trespasser. The authors' hope is that bystanders will "homestead" the right to care for evicted babies and reduce the number of human deaths. They argue that life begins at conception and state that the act of abortion must be conceptually separated into the acts of:
Paper abortion, also known as a financial abortion, male abortion or a statutory abortion, is the proposed ability of the biological father, before the birth of the child, to opt out of any rights, privileges, and responsibilities toward the child, including financial support. By this means, before a child is born, a man would be able to absolve himself of both the privileges and demands of fatherhood.
