The morality and legality of abortion is an important topic in applied ethics and is also discussed by legal scholars and theologians. Important facts about abortion are also researched by sociologists and historians.
Abortion has existed in most societies, although it has often been opposed by institutionalized governments and religions. In the 20th century abortion became legally accepted in most of Europe and in the United States (In some European countries, such as Germany and Spain, abortion is technically illegal even in the first trimester, although prosecution typically does not occur.) Additionally, abortion is legal and accepted in China, India and other populous countries.
The Catholic Church remains opposed to the procedure, however, and in certain countries, notably the United States and the (predominantly Catholic) Republic of Ireland, the controversy is still extremely active, to the extent that even the names of the respective positions are subject to heated debate. While those on both sides of the argument are generally peaceful, if heated, in their advocacy of their positions, the debate is sometimes characterized by violence.
The central dilemma in the abortion debate is the clash of presumed or perceived rights. On one hand is the right to life, and on the other is a woman's right to control her own body. One part of the issue involves defining when a fetus becomes a person, and thus gains the inherent right to life. Even if that could be agreed upon, that right must be weighed against the rights of the mother.
How can these respective rights be balanced?
The extreme "pro-life" argument is that an embryo (and later, a fetus) is a human life—innocent and worthy of protection—from the moment of conception and, possessing a right to life that must be respected. Therefore, abortion under any circumstance is the killing of an innocent person—murder—and thus wrong.
The extreme "pro-choice" argument is that a woman's right to control her body always outweighs any right claimed for the fetus up to the moment of birth, and that abortion is acceptable under any circumstance.
Outside of the extremes, balance can sometimes be reached on certain issues. For instance, some "pro-life" advocates do not consider contraceptive drugs (such as the morning-after pill) to be abortion, though while these drugs usually work by preventing conception, they can also work by preventing a fertilized egg from implanting. Also, many "pro-life" advocates tolerate abortion in cases where the mother's life or health are at stake or in cases of rape or incest. "Pro-choice" advocates often accept a ban on abortions of "viable" fetuses, which are those that are old enough to survive outside of the mother's womb (although debate ensues as to when a fetus is viable and what constitutes viability).
Underlying this debate is another debate, over the role of the state: to what extent should the state interfere with a woman's pregnancy to protect the public interest, or to what extent should the state protect the general interest, even if it means controlling a woman's pregnancy? This is a major issue in a number of countries, such as India and China, which have tried to enforce forms of birth control (including forced sterilization), and the United States, which historically has limited access to birth control.
The competing labels for positions tends to blur over important differences in what can be advocated about abortion. In discussions of abortion it is of paramount importance to distinguish the variety of conclusions that can be advocated on the subject. First, consider the unequivocal positions:
There is clearly a difference, for example, between the views that abortion is immoral and that it should be illegal. It is possible to hold the views both that every instance of abortion is immoral and also that it should never be illegal.
There are, in fact, several other positions that represent even greater extremes than these, though they are not, strictly speaking, positions about abortion per se. On the one hand, there are some persons who believe that birth control is morally impermissible; they argue that the choice of whether a child should be created should always be left to God. On the other hand, there are persons such as professor Peter Singer, who thinks that life of an infant is less important than that of an older child or an adult, and that infanticide is, in some cases, morally permissible and should, in those cases, be legally permissible. And some take the position that abortion ought to be compulsory, either in certain situations — the Twelve Tables of Roman law required that deformed children be put to death.
There are also several more qualified positions about abortion, which represent mid-ground between the relatively extreme positions that abortion is always moral, or never, and that it should always be legal, or never. That is, the qualified positions are that abortion is sometimes moral and at other times not, and in some cases it should be legal and in other cases not. Examples of these positions are:
The latter position represents a point of serious controversy among abortion foes, who feel that, in those cases where the completion of a pregnancy would likely result in severe permanent physical injury or death for the mother, abortion is morally permissible and/or should (continue to) be legally permitted. Some oppose even this exception, however. Similarly, when pregnancy is the result of rape or incest, the situation created—where the mother is bearing a rapist's child, or her close relative's—is regarded as so morally repugnant that there is no moral obligation, and should be no legal obligation, to continue the pregnancy. Again, some people will not make an exception even in such cases. Some justify this with the severe depression, anxiety, and regret women may experience post-abortion, or by saying that the child has the right to be born regardless of the circumstances of conception.
In many countries, but most strikingly in the United States, the scientific, religious, and philosophical communities have remained polarized on most of these issues.
The political debate tends to center on questions of legality, though such debates are often based on moral questions. In the United States, the political debate centers on two questions:
As of November 5, 2003, United States President George W. Bush signed into law the "Partial-birth Abortion Ban Act" which makes it illegal for anyone to perform the procedure. However, some abortion practitioners represented by the ACLU have already filed a lawsuit protesting the law. So, at present, the question still has a viable political life in the United States.
The second question is a matter of deep concern for many, but the chances of Roe v. Wade being overturned are low at present. Related issues such as requiring parental consent for minors, waiting periods, and education, are also in contention in some states. Other questions, such as federal funding of abortions, and acts such as the "Unborn Victims of Violence Act" also are in contention in the United States.
The controversy over abortion remains a very emotionally charged issue, and difficult to resolve.
[1] The issue is actually more complicated than this, as opponents to a "health of the mother" exception contend that legally this would create a loophole legalizing any abortion. These opponents also claim that the procedure which is being banned is never necessary to preserve a woman's health.
Briefly, the basis of the view that all, or almost all, abortion should be illegal is the belief that the life of a person—and all political rights attending it—begins at conception. Given that, one is invited to consider the common assumption that each innocent person is entitled to the protection of society against the deliberate destruction of its life by another person. The latter is a rough statement of the right to life, which is guaranteed in many basic legal and political documents such as the United States Declaration of Independence and the Universal Declaration of Human Rights, and is the basis of laws against murder. Thus, the pro-life view is that elective abortion is the deliberate killing of an innocent person and therefore not morally justifiable, regardless of the law. But since the law should be consistent with morality, elective abortion ought to be regarded legally as murder. Again, this is the basic argument against the legality of abortion. There exist people who morally disapprove of abortion but who, for other reasons, deny that abortion should be legally proscribed. This will be explained below.
One could also oppose the legality of abortion on nonreligious grounds, which is a strategy employed by those who believe that their personal religious considerations have no proper place in public policy debate. One could say, for example, that the proposition that all humans are persons and that because a human life begins at conception so too does personhood--and the moral rights that entails. This is a genetic view of "human life" which begins with the union of parental gametes that creates a new individual with a distinct genetic identity, initiating the process that ends with death. Proponents of this view recognize that there is a period of several months during which the child is biologically dependent upon the mother to sustain its life, but they regard the obligation of a parent to protect the life of its child as one which ought to be an uncontroversial societal norm. Opponents argue that biologists are by no means unanimous in their agreement about when a human life begins. Other views of the human identity place the beginning of human life at later time. For example, the embryological view holds that individual human life begins when an embryo no longer is capable of forming twins, approximately 12 days after conception.
Those who believe that abortion is morally permissible, and should remain legally permissible, typically have a different view of the issue as to when a human becomes a person that deserves a right to life. Many hold that an embryo or fetus which is incapable of surviving outside the mother's womb (a status generally reached no sooner than 17 weeks into gestation) is not recognizable as a human life separate from the mother's body, while others hold that human life starts with the development of a nervous system. Those opposed to abortion at any stage counter by saying that it is arbitrary when an embryo or fetus is to be considered a separate human life, and that future technology may make it possible for a human life to develop entirely outside of a mother's body. Others argue that a fetus does not have the capacity for thought, self awareness, etc. required for personhood and thus does not have a strong right to life, in line with common treatment of animals and severely brain damaged (vegetative) humans.
For those who believe that abortion should be legally permissible (regardless of its morality), one of the most common arguments is based on privacy rights. Abortion rights advocates hold that a woman's right to determine what happens with her body (including whether to carry a pregnancy to term) is private, is not to be interfered with by outside influences, and negates all rights of her offspring. This point was given an interesting formulation by the philosopher Abortion law
