In December of 1986, members of an "animal-liberation" group called True Friends broke into the Sema, Inc., laboratories in Rockville, Maryland, and took four baby chimpanzees from among the facility's 600 primates. The four animals, part of a group of thirty being used in hepatitis research, had been housed individually in "isolettes"—small stainless-steel chambers with sealed glass doors. A videotape produced by True Friends shows other primates that remained behind. Some sit behind glass on wire floors, staring blankly. One rocks endlessly, banging violently against the side of his cage. Another lies dead on his cage's floor. The "liberation" action attracted widespread media attention to Sema, which is a contractor for the National Institutes of Health, the federal agency that funds most of the animal research in this country. Subsequently the NIH conducted an investigation into conditions at the lab and concluded that the use of isolettes is justified to prevent the spread of diseases among infected animals.
For members of True Friends and other animal-rights groups, however, such a scientific justification is irrelevant to what they see as a moral wrong; these activists remain frustrated over conditions at the laboratory. This conflict between the NIH and animal-rights groups mirrors the tension between animal researchers and animal-rights advocates generally. The researchers' position is that their use of animals is necessary to advance human health care and that liberation actions waste precious resources and impede the progress of science and medicine. The animal rights advocates' position is that animal research is an ethical travesty that justifies extraordinary, and even illegal, measures.
The Sema action is part of a series that numbers some six dozen to date and that began, in 1979, with a raid on the New York University Medical Center, in which members of a group known as the Animal Liberation Front (ALF) took a cat and two guinea pigs. The trend toward civil disobedience is growing. For example, last April members of animal-rights groups demonstrated at research institutions across the country (and in other countries, including Great Britain and Japan), sometimes blocking entrances to them by forming human chains. In the United States more than 130 activists were arrested, for offenses ranging from blocking a doorway and trespassing to burglary.
To judge by everything from talk-show programs to booming membership enrollment in animal-rights groups (U.S. membership in all groups is estimated at 10 million), the American public is increasingly receptive to the animal-rights position. Even some researchers admit that raids by groups like True Friends and the ALF have exposed egregious conditions in particular labs and have been the catalyst for needed reforms in the law. But many members of animal-rights groups feel that the recent reforms do not go nearly far enough. Through dramatic animal-liberation actions and similar tactics, they hope to force what they fear is a complacent public to confront a difficult philosophical issue: whether animals, who are known to have feelings and psychological lives, ought to be treated as mere instruments of science and other human endeavors.
The ALF is probably the most active of the world's underground animal-rights groups. It originated in England, where the animal-protection movement itself began, in 1824, with the founding of the Royal Society for the Prevention of Cruelty to Animals. The ALF evolved from a group called the Band of Mercy, whose members sabotaged the vehicles of hunters and destroyed guns used on bird shoots. It now has members across Europe, and in Australia, New Zealand, Africa, and Canada, as well as the United States. It does not, however, constitute a unified global network. The American wing of the ALF was formed in 1979. The number of its members is unknown, but their ages range from eighteen to over sixty. Some are students, some are blue-collar workers, and many belong to the suburban middle class.
Animal-rights activists feel acute frustration over a number of issues, including hunting and trapping, the destruction of animals' natural habits, and the raising of animals for food. But for now the ALF considers animal research the most powerful symbol of human dominion over and exploitation of animals, and it devotes most of its energies to that issue. The public has been ambivalent, sometimes cheering the ALF on, at other times denouncing the group as "hooligans." However one chooses to characterize the ALF, it and other groups like it hold an uncompromising "rights view" of ethics toward animals. The rights view distinguishes the animal-protection movement of today from that of the past and is the source of the movement's radicalism.
"They All Have a Right to Live"
Early animal-protection advocates and groups, like the RSPCA, seldom talked about rights. They condemned cruelty—that is, acts that produce or reveal bad character. In early-nineteenth-century England campaigners against the popular sport of bull-baiting argued that it "fostered every bad and barbarous principle of our nature." Modern activists have abandoned the argument that cruelty is demeaning to human character ("virtue thought") in favor of the idea that the lives of animals have intrinsic value ("rights thought"). Rights thought doesn't necessarily preclude the consideration of virtue, but it mandates that the measure of virtue be the foreseeable consequences to others of one's acts.
"Michele" is thirty-five and works in a bank in the East. She has participated in many of the major ALF actions in the United States. One of the missions involved freeing rats, and she is scornful of the idea that rats aren't worth the effort. "That attitude is rather pathetic, really" she says. "These animals feel pain just like dogs, but abusing them doesn't arouse constituents' ire, so they don't get the same consideration. They all have a right to live their lives. Cuteness should not be a factor.
While most people would agree that animals should not be tortured, there is no consensus about animals' right to live (or, more precisely, their right not to be killed). Even if one can argue, as the British cleric Humphrey Primatt did in 1776, that "pain is pain, whether it be inflicted on man or on beast," it is more difficult to argue that the life of, say, a dog is qualitatively the same as that of a human being. To this, many animal-rights activists would say that every morally relevant characteristic that is lacking in all animals (rationality might be one, according to some ways of defining that term) is also lacking in some "marginal" human beings, such as infants, or the senile, or the severely retarded. Therefore, the activists argue, if marginal human beings have the right to live, it is arbitrary to hold that animals do not. Opponents of this point of view often focus on the differences between animals and "normal" human beings, asserting, for instance, that unlike most human adults, animals do not live by moral rules and therefore are not part of the human "moral community."
The credibility of the animal-rights viewpoint, however, need not stand or fall with the "marginal human beings" argument. Lives don't have to be qualitatively the same to be worthy of equal respect. One's perception that another life has value comes as much from an appreciation of its uniqueness as from the recognition that it has characteristics that are shared by one's own life. (Who would compare the life of a whale to that of a marginal human being?) One can imagine that the lives of various kinds of animals differ radically, even as a result of having dissimilar bodies and environments—that being an octopus feels different from being an orangutan or an oriole. The orangutan cannot be redescribed as the octopus minus, or plus, this or that mental characteristic; conceptually, nothing could be added to or taken from the octopus that would make it the equivalent of the oriole. Likewise, animals are not simply rudimentary human beings, God's false steps, made before He finally got it right with us.
Recognizing differences, however, puts one on tentative moral ground. It is easy to argue that likes ought to be treated alike. Differences bring problems: How do we think about things that are unlike? Against what do we measure and evaluate them? What combinations of likeness and difference lead to what sorts of moral consideration? Such problems may seem unmanageable, and yet in a human context we routinely face ones similar in kind if not quite in degree: our ethics must account for dissimilarities between men and women, citizens and aliens, the autonomous and the helpless, the fully developed and the merely potential, such as children or fetuses. We never solve these problems with finality, but we confront them.
One might be tempted to say that the problems are complicated enough without bringing animals into them. There is a certain attractiveness to the idea that animals—lacking membership in the human and moral communities, and unable to reciprocate moral concern—deserve little consideration from us. After all, doesn't one have obligations toward members of one's family and community that do not apply to outsiders? Yet this appeal to a sense of community fails to take into account certain people who likewise lack membership and yet have moral claims against us. Consider future people, particularly those who will live in the distant future. Suppose that our dumping of certain toxic wastes could be predicted to cause widespread cancer among people five hundred years in the future. Would we not have a heavy moral burden to refrain from such dumping? Probably most of us would say that we would. Yet in what meaningful sense can it be said that people we will never meet, who will never do anything for us, and whose cultures and ethical systems will likely be profoundly different from our own, are members of our community? Membership may count for something, but it is clearly not a necessary condition for moral entitlement. Also, some animals—my dog, for instance—may more sensibly be characterized as members of our community than may some human beings, such as those of the distant future.
Both advocates and opponents of animal rights also invoke utilitarianism in support of their points of view. Utilitarianism holds that an act or practice is measured by adding up the good and the bad consequences—classically, pleasure and pain—and seeing which come out ahead. There are those who would exclude animals from moral consideration on the grounds that the benefits of exploiting them outweigh the harm. Ironically, though, it was utilitarianism, first formulated by Jeremy Bentham in the eighteenth century, that brought animals squarely into the realm of moral consideration. If an act or practice has good and bad consequences for animals, then these must be entered into the moral arithmetic. And the calculation must be genuinely disinterested. One may not baldly assert that one's own interests count for more. Animal researchers may truly believe that they are impartially weighing all interests when they conclude that human interests overwhelm those of animals. But a skeptical reader will seldom be persuaded that they are in fact doing so. For instance, a spokesperson for a research institution that was raided by the ALF wrote in the Los Angeles Times that we should not be "more concerned with the fate of these few dogs than with the millions of people who are cancer victims." Note the apparent weighing: "few" versus "millions." But her lack of impartiality was soon revealed by this rhetorical question: "Would they the ALF really save an animal in exchange for the life of a child?"
Even true utilitarianism is incomplete, though, without taking account of rights. For example, suppose a small group of aboriginal tribespeople were captured and bred for experiments that would benefit millions of other people by, say, resulting in more crash-worthy cars. Would the use of such people be morally acceptable? Surely it would not, and that point illustrates an important function of rights thought: to put limits on what can be done to individuals, even for the good of the many. Rights thought dictates that we cannot kill one rights-holder to save another—or even more than one other—whether or not the life of the form is "different" from that of the latter.
Those who seek to justify the exploitation of animals often claim that it comes down to a choice: kill an animal or allow a human being to die. But this claim is misleading, because a choice so posed has already been made. The very act of considering the taking of life X to save life Y reduces X to the status of a mere instrument. Consider the problem in a purely human context. Imagine that if Joe doesn't get a new kidney he will die. Sam, the only known potential donor with a properly matching kidney, himself has only one kidney and has not consented to give it—and his life—up for Joe. Is there really a choice? If the only way to save Joe is to kill Sam, then we would be unable to do so—and no one would say that we chose Sam over Joe. Such a choice would never even be contemplated.
In another kind of situation there is a choice. Imagine that Joe and Sam both need a kidney to survive, but we have only one in our kidney bank. It may be that we should give the kidney to Joe, a member of our community, rather than to Sam, who lives in some distant country (though this is far from clear—maybe flipping a coin would be more fair). Sam (or the loser of the coin flip) could not complain that his rights had been violated, because moral claims to some resource-positive claims must always be dependent on the availability of that resource. But the right not to be treated as if one were a mere resource or instrument—negative, defensive claims—is most fundamentally what it means to say that one has rights. And this is what members of the ALF have in mind when they declare that animals, like human beings, have rights.
Where, one might wonder, should the line be drawn? Must we treat dragonflies the same as dolphins? Surely not. Distinctions must be made, though to judge definitively which animals must be ruled out as holders of rights may be impossible even in principle.
In legal or moral discourse we are virtually never able to draw clear lines. This does not mean that drawing a line anywhere, arbitrarily, is as good as drawing one anywhere else.
The line-drawing metaphor, though, implies classifying entities in a binary way: as either above the line, and so entitled to moral consideration, or not. Binary thinking misses nuances of our moral intuition. Entities without rights may still deserve moral consideration on other grounds: one may think that a dragonfly doesn't quite qualify for rights yet believe that it would be wrong to crush one without good reason. And not all entities with rights need be treated in precisely the same way. This is apparent when one compares animals over whom we have assumed custody with wild animals. The former, I think, have rights to our affirmative aid, while the latter have such rights only in certain circumstances. Similar distinctions can be made among human beings, and also between human beings and particular animals. For example, I recently spent $ 1,000 on medical care for my dog, and I think he had a right to that care, but I have never given such an amount to a needy person on the street. Rights thought, then, implies neither that moral consideration ought to be extended only to the holders of rights nor that all rights-holders must be treated with a rigid equality. It implies only that rights-holders should never be treated as if they, or their kind, didn't matter.
Animals, Refrigerators, and Can Openers
The question of man's relationship with animals goes back at least to Aristotle, who granted that animals have certain senses—hunger, thirst, a sense of touch—but who held that they lack rationality and therefore as "the lower sort they are by nature slaves, and . . . should be under the rule of a master." Seven centuries later Saint Augustine added the authority of the Church, arguing that "Christ himself teaches that to refrain from the killing of animals . . . is the height of superstition, for there are no common rights between us and the beasts, . . ." Early in the seventeenth century René Descartes argued that, lacking language, animals cannot have thoughts or souls and thus are machines.
One may be inclined to dismiss such beliefs as archaic oddities, but even today some people act as if animals were unfeeling things. I worked in a research lab for several summers during college, and I remember that it was a natural tendency to lose all empathy with one's animal subjects. My supervisor seemed actually to delight in swinging rats around by their tails and flinging them against a concrete wall as a way of stunning the animals before killing them. Rats and rabbits, to those who injected, weighed, and dissected them, were little different from cultures in a petri dish: they were just things to manipulate and observe. Feelings of what may have been moral revulsion were taken for squeamishness, and for most of my lab mates those feelings subsided with time.
The first animal-welfare law in the United States, passed in New York State in 1828, emphasized the protection of animals useful in agriculture. It also promoted human virtue with a ban on "maliciously and cruelly" beating or torturing horses, sheep, or cattle. Today courts still tend to focus on human character, ruling against human beings only for perpetrating the most shocking and senseless abuse of animals. Indeed, courts sometimes have difficulty taking animal-abuse cases seriously. For instance, in 1986 a California man who had been convicted of allowing a fifty-year-old tortoise, Rocky, in his petting zoo to suffer untreated from maladies including infected eyes, labored breathing, and dehydration appealed the lower court's order removing the animal from his custody. The state argued that the defendant's rights to Rocky should be terminated just as parental rights might be terminated for abusing a child. The court, in rejecting this analogy, quipped that while "a child preparing for homework or cleaning a bedroom may exhibit turtle-like qualities or creep toward school in turtle pace, we decline to equate title to a tortoise to the relationship between a parent and a child." Not to be outdone, another judge wrote, in a concurring opinion, that "hopefully our decision will forestall the same problem should we be faced with Rocky II."
Most states leave the regulation of medical research to Washington. In 1966 Congress passed the Laboratory Animal Welfare Act, whose stated purpose was not only to provide humane care for animals but also to protect the owners of dogs and cats from theft by proscribing the use of stolen animals. (Note the vocabulary of property law; animals have long been legally classified as property.) Congress then passed the Animal Welfare Act of 1970, which expanded the provisions of the 1966 act to include more species of animals and to regulate more people who handle animals. The AWA was further amended in 1976 and in 1985.
The current version of the AWA mandates that research institutions meet certain minimum requirements for the handling and the housing of animals, and requires the "appropriate" use of pain-killers. But the act does not regulate research or experimentation itself, and allows researchers to withhold anesthetics or tranquilizers "when scientifically necessary." Further, while the act purports to regulate dealers who buy animals at auctions and other markets to sell to laboratories, it does little to protect those animals. For instance, dealers often buy animals at "trade days," or outdoor bazaars of dogs and cats; some people bring cats by the sackful, and, according to one activist, "sometimes you see the blood coming through."
The 1985 amendments to the AWA were an attempt to improve the treatment of animals in laboratories, to improve enforcement, to encourage the consideration of alternative research methods that use fewer or no animals, and to minimize duplication in experiments. One notable change is that for the first time, research institutions using primates must keep them in environments conducive to their psychological well-being; however, some animal-rights activists have expressed skepticism, since the social and psychological needs of primates are complex, and the primary concern of researchers is not the interests of their animal subjects. Last September a symposium on the psychological well being of captive primates was held at Harvard University. Some participants contended that we lack data on the needs of the thirty to forty species of primates now used in laboratories. Others suggested that the benefits of companionship and social life are obvious.
The U.S. Department of Agriculture is responsible for promulgating regulations under the AWA and enforcing the law. Under current USDA regulations the cages of primates need only have floor space equal to three times the area occupied by the animal "when standing on four feet"—in the words of the USDA, which has apparently forgotten that primates have hands. The 1985 amendments required the USDA to publish final revised regulations, including regulations on the well being of primates, by December of 1986. At this writing the department has yet to comply, and some activists charge that the NIH and the Office of Management and Budget have delayed the publication of the new regulations and attempted to undermine them.
One may believe that virtue thought—which underlies current law—and rights thought should protect animals equally. After all, wouldn't a virtuous person or society respect the interests of animals? But virtue thought allows the law to disregard these interests, because virtue can be measured by at least two yardsticks: by the foreseeable effects of an act on the interests of an animal or by the social utility of the act. The latter standard was applied in a 1983 case in Maryland in which a researcher appealed his conviction for cruelty to animals after he had performed experiments that resulted in monkeys' mutilating their hands. Overturning the conviction, the Maryland Court of Appeals wrote that "there are certain normal human activities to which the infliction of pain to an animal is purely incidental"—thus the actor is not a sadist—and that the state legislature had intended for these activities to be exempt from the law protecting animals.
The law, of course, is not monolithic. Some judges have expressed great sympathy for animals. On the whole, though, the law doesn't recognize animal rights. Under the Uniform Commercial Code, for instance, animals—along with refrigerators and can openers—constitute "goods."
Alternatives to Us-Versus-Them
Estimates of the number of animals used each year in laboratories in the United States range from 17 million to 100 million: 200,000 dogs, 50,000 cats, 60,000 primates, 1.5 million guinea pigs, hamsters, and rabbits, 200,000 wild animals, thousands of farm animals and birds, and millions of rats and mice. The conditions in general—lack of exercise, isolation from other animals, lengthy confinement in tiny cages—are stressful. Many experiments are painful or produce fear, anxiety, or depression. For instance, in 1987 researchers at the Armed Forces Radiobiology Research Institute reported that nine monkeys were subjected to whole-body irradiation; as a result, within two hours six of the monkeys were vomiting and hypersalivating. In a proposed experiment at the University of Washington pregnant monkeys, kept in isolation, will be infected with the simian AIDS virus; their offspring, infected or not, will be separated from the mothers at birth.
Not all animals in laboratories, of course, are subjects of medical research. In the United States each year some 10 million animals are used in testing products and for other commercial purposes. For instance, the United States Surgical Corporation, in Norwalk, Connecticut, uses hundreds of dogs each year to train salesmen in the use of the company's surgical staple gun. In 1981 and 1982 a group called Friends of Animals brought two lawsuits against United States Surgical to halt these practices. The company successfully argued in court that Friends of Animals lack "standing" to sue, since no member of the organization had been injured by the practice; after some further legal maneuvering by Friends of Animals both suits were dropped. Last November a New York City animal-rights advocate was arrested as she planted a bomb outside United States Surgical's headquarters.
In 1987, according to the USDA, 130,373 animals were subjected to pain or distress unrelieved by drugs for "the purpose of research or testing." This figure, which represents nearly seven percent of the 1,969,123 animals reported to the USDA that year as having been "used in experimentation," ignores members of species not protected by the AWA (cold-blooded animals, mice, rats, birds, and farm animals). Moreover, there is reason to believe that the USDNs figures are low. For example, according to the USDA, no primates were subjected to distress in the state of Maryland, the home of Sema, in any year from 1980 to 1987, the last year for which data are available.
Steps seemingly favorable to animals have been taken in recent years. In addition to the passage of the 1985 amendments to the AWA, the Public Health Service, who includes the NIH, has revised "Policy on Humane Care and Use of Laboratory Animals," and new legislation has given legal force to much of this policy. Under the revised policy, institutions receiving NIH or other PHS funds for animal research must have an "institutional animal care and use committee" consisting of at least five members, including one nonscientist and one person not affiliated with the institution.
Many activists are pessimistic about these changes, however. They argue that the NIH has suspended funds at noncompliant research institutions only in response to political pressure, and assert that the suspensions are intended as a token gesture, to help the NIH regain lost credibility. They note that Sema, which continues to keep primates in isolation cages (as regulations permit), is an NIH contractor whose principal investigators are NIH employees. As to the makeup of the animal-care committees, animal-rights advocates say that researchers control who is appointed to them. In the words of one activist, "The brethren get to choose."
However one interprets these changes, much remains the same. For example, the AWA authorizes the USDA to confiscate animals from laboratories not in compliance with regulations, but only if the animal "is no longer required . . . to carry out the research, test or experiment"; the PHS policy mandates pain relief "unless the procedure is justified for scientific reasons." Fundamentally, the underlying attitude that animals may appropriately be used and discarded persists.
If the law is ever to reflect the idea that animals have rights, more drastic steps—such as extending the protection of the Constitution to animals—must be taken. Constitutional protection for animals is not an outlandish proposition. The late U.S. Supreme Court Justice William O. Douglas wrote once, in a dissenting opinion, that the day should come when "all of the forms of life . . . will stand before the court—the pileated woodpecker as well as the coyote and bear, the lemmings as well as the trout in the streams."
Suppose, just suppose, that the AWA were replaced by an animal-rights act, which would prohibit the use by human beings of any animals to their detriment. What would be the effect on medical research, education, and product testing? Microorganisms; tissue, organ, and cell cultures; physical and chemical systems that mimic biological functions; computer programs and mathematical models that simulate biological interactions; epidemiologic data bases; and clinical studies have all been used to reduce the number of animals used in experiments, demonstrations, and tests. A 1988 study by the National Research Council, while finding that researchers lack the means to replace all animals in labs, did conclude that current and prospective alternative techniques could reduce the number of animals—particularly mammals—used in research.
Perhaps the report would have been more optimistic if scientists were as zealous about conducting research to find alternatives as they are about animal research. But we should not be misled by discussions of alternatives into thinking that the issue is merely empirical. It is broader than just whether subject A and procedure X can be replaced by surrogates B and Y. We could undergo a shift in world view: instead of imagining that we have a divine mandate to dominate and make use of everything else in the universe, we could have a sense of belonging to the world and of kinship with the other creatures in it. The us-versus-them thinking that weighs animal suffering against human gain could give way to an appreciation that "us" includes "them." That's an alternative too.
Some researchers may insist that scientists should not be constrained in their quest for knowledge, but this is a romantic notion of scientific freedom that never was and should not be. Science is always constrained, by economic and social priorities and by ethics. Sometimes, paradoxically, it is also freed by these constraints, because a barrier in one direction forces it to cut another path, in an area that might have remained unexplored.
Barriers against the exploitation of animals ought to be erected in the law, because law not only enforces morality but defines it. Until the law protects the interests of animals, the animal-rights movement will by definition be radical. And whether or not one approves of breaking the law to remedy its shortcomings, one can expect such activities to continue. "I believe that you should do for others as you would have done for you," one member of the ALF says. "If you were being used in painful experiments, you'd want someone to come to your rescue."
