Embryos in the Original Position:

Why Justice as Fairness Supports a Pro-Life Stance

Russell DiSilvestro
Bowling Green State University

How should followers of the late John Rawls think about the moral status of the human embryo? Those familiar with Rawls’ work might assume that it either does not provide enough material to formulate an answer to this question, or that the answer it provides is decidedly liberal. After all, Rawls has been the most recognizable intellectual champion of liberalism for the past several decades, and his few but famous remarks on the issue of abortion are clearly in line with a pro-choice framework. Nevertheless, I argue in this paper that other aspects of Rawls’ own writings lead naturally and directly into a staunchly conservative position regarding the defense of human embryos. This is most clearly proved from his remarks on how parties in his original position would think about issues like paternalism and human equality. In each case, Rawls discusses why the parties would seek to protect themselves in case they end up as an incapacitated or undeveloped human being when the veil of ignorance is lifted. My simple but surprising thesis, then, is that if one adopts Rawls’ own framework of justice as fairness, it is clear that human embryos should be entitled to the claims of justice.

A Rational Look at the Abortion Controversy

A Rational[1] Look at the Abortion Controversy

by Mario Derksen, M.A. cand.

International Catholic University

Presented on April 26, 2003
at the Ohio University Student Conference on Applied Ethics, Athens, Ohio

Revised and Updated: May 1, 2003

One of the most hotly contested issues inside and outside of biomedical ethics today is abortion. The discussion received a new impetus at the release of the controversial abortion drug RU-486, “a pill to increase access to abortions and let women get them privately from their own doctor instead of facing shouting protesters at clinics.”[2] As is the case with all controversial issues, there are very passionate people on both sides of the fence. Unfortunately, a heated discussion on abortion can easily and quickly turn into a battle of rhetoric rather than a dialectic of reason. But the guiding light in such a discussion must always be reason, not rhetoric or other fallacies, for only reason can solve this issue and judge which side is correct.

In this brief essay, I shall attempt to clear away some of the confusion present in typical abortion debates by cooling the rhetoric with reason enlightened by scientific facts. Specifically, I will examine two common pro-abortion arguments made by Mary Anne Warren and Judith Jarvis Thomson and demonstrate that they cannot stand up to rational scrutiny and therefore fail to justify abortion. I shall also use a
”quadrilemma” argument similar to that of Peter Kreeft’s to show that, aside from all specific argumentation, abortion cannot be morally justified.

Before even beginning to discuss the issue of abortion, it is imperative to agree upon a starting point from which to reason. The fact that some people differ even about this very point tends to render the pro-abortion and the anti-abortion paradigms somewhat “incommensurable,” and this is probably one major reason why people are tempted to arrive at different conclusions about this topic. It seems to me, however, that to start with the definition of abortion and an examination of the beings involved would be a fair move.

Abortion is the unnatural termination of a pregnancy by killing (at least) one human fetus. This definition is not contested, and I think it seems clear that it is correct. Science confirms that life begins at conception,[3] and that this life is human is a—scientific as well as logical—necessity, because it is the product of two humans, and humans can only produce humans. Ergo, the fetus involved is human. Secondly, the fetus is, at least scientifically speaking, a singular and individual organism, as evidenced by his own unique genetic make-up, which he shares with no other human being on earth (unless he have an identical twin). There is thus an essential difference between a human fetus and, say, a tumor or similar parasite. Finally, that the fetus is alive is confirmed through empirical observation, and hence forcing that life to come to an end involves at least some sort of killing. Therefore, the unavoidable conclusion is that abortion deliberately and forcibly puts to death a human being. Again, this definition is uncontested and thus I shall not dwell on it any further. Rather, I shall now turn to the moral implications necessarily connected with abortion.

The question that arises is as to whether or not abortion is morally justifiable. It cannot be wrong by definition, since sometimes thereis moral justification for forcibly putting to death another human being, in such cases as self-defense, just war, or capital punishment.[4]Hence, it is reasonable to raise the question whether abortion might be another such instance where one is justified in taking a human life.

The pro-abortion side submits that it is, and different arguments have been put forward to substantiate that claim. A very popular one is the contention that human fetuses are not persons, and that only persons have a right to life and justice against others, at least when these others’ rights are at stake. Mary Anne Warren’s essay “On the Moral and Legal Status of Abortion”[5] argues just that. Curiously, though, Warren does not indicate in her essay why one should accept the view that one ought to be a person in order to have moral rights in the first place; it seems that she considers it self-evident that this is so, mentioning only that she thinks “there are very good reasons fornot defining the moral community”[6] in such a way that every human being is ipso facto included. Be that as it may, she asks: “What moral characteristics entitle an entity to be considered a person?”[7] and goes on to list five “traits which are most central to the concept of personhood”[8] in her opinion. They are: (1) consciousness, (2) reasoning, (3) self-stimulated activity, (4) the capability to communicate, and (5) the presence of self-concepts and self-awareness.

It is here that reason ought to make an objection. While Warren may think that the categories she lists are sufficient for personhood, I see no reason to believe that they are necessary. In fact, the author herself admits a few lines later that we do not “need to insist that any one of these criteria is necessary for personhood.”[9] But if not “any one” of them is necessary, then none of them are, and if that’s the case, what does her argument prove? And what if one thinks that it is totally unacceptable to define personhood in terms of functional abilities at all? For Warren’s argument to be forceful, one would have to presuppose her functionalist paradigm as true, i.e. the basic idea that there even are criteria a human being must meet in order to be considered a person. But this would be an instant of question-begging—after all, one could very well adopt the view that all humans are persons in virtue of their humanity, and thus being human necessarily implies being a person. I maintain that this alternative view is not only true but also does not carry any problems with it—Warren’s own objection notwithstanding, as will be shown later.

On the other hand, Warren’s functionalism comes with plenty of problems. For one thing, even if one agrees with Warren’s position that the functionalist view of human personhood is true, the criteria proposed by her could be rejected by anyone who disagrees with them, since they are imposed rather gratuitously, and what is gratuitously asserted can be just as gratuitously denied.

Secondly, a major problem Warren’s view faces is the fact that it disregards Francis Beckwith’s argument that “personhood is not something that arises when certain functions are in place, but rather is something that grounds these functions, whether or not they are ever actualized in the life of a human being,”[10] for “to claim that a human being can be functional, become non-functional, and then return to a state of function is to assume that there is some underlying personal unity to this individual.”[11] What Beckwith means by this is that, supposing that John Doe has a car accident and becomes comatose for three months, according to the functionalist view proposed by Warren, one would have to conclude that while Doe was in the coma, he ceased to be a person since he didn’t meet any of her proposed five criteria for personhood, and that when he awoke, he became a person again.

But this is surely absurd. Therefore, Beckwith concludes, “it is intelligible for us to say that the person who has returned to functional capacity is the same person who was functional prior to being in a non-functional state and yet continued to exist while not functioning.”[12] There must be some underlying personal unity, then, unless we wish to say that John Doe before the coma was a different person from the John Doe after the coma. While this objection to Warren’s position can perhaps be elaborated upon, as it is, it does present a major obstacle to her notion that human beings must first meet certain requirements before they can be considered persons, i.e. beings with moral rights.

Earlier I mentioned that Warren does not give us any justification for embracing a functionalist paradigm as far as personhood is concerned. This statement needs qualification, however. Warren does mention that the view that personhood is intrinsic to any human being from the first moment of his existence carries with it the problem that it makes the traditional syllogism against abortion[13]question-begging. But this is false. It does not make the traditional syllogism any more question-begging than the syllogism that since Socrates is a man and all men are mortal, therefore Socrates is mortal. The fact that the conclusion follows with great clarity and ease is not because it begs the question but because it is a deductive argument—and it is the nature of deduction to render “obvious” conclusions, since all deduction does is spell out what is already contained in the premises. Therefore, it should not be surprising that the conclusion of the traditional anti-abortion syllogism follows with relative ease. And this most certainly does not disprove the validity of the syllogism or suggest that it contains a fallacy, and hence the humanity-implies-personhood view is not refuted or infringed upon.

So, what reasons does Warren have to reject the view that humanity implies personhood? None, really. So, why does she reject it? She rejects it because otherwise she would have to admit that abortion is impermissible (she agrees, after all, that the statement “it is wrong to kill innocent human beings” is “a self-evident moral truth”[14]), and this is a conclusion she does not desire. In other words, it seems to me that Warren rejects the view that humanity necessarily implies personhood (or that being human suffices to have moral rights) precisely and only because it would make abortion impermissible. She presupposes that abortion is justified and thus proceeds to select only such criteria for personhood as allow for her preconceived conclusion, i.e. criteria that are not met by human fetuses.[15]Thus, she has ruled out from the beginning the possibility that abortion is wrong. But surely this is question-begging!

Of course, not all abortion advocates base their justification of abortion on a lack of personhood on the part of the preborn human. Some, such as Judith Jarvis Thomson, argue instead that even if the fetus is a person, abortion can still be morally justified. Certainly, such a justification, if valid, would make a much more forceful case for abortion than any attempt to base it on a lack of personhood. Hence, I will now proceed to examine Judith Thomson’s main argument in her essay “A Defense of Abortion.”[16]

According to Thomson, we are to imagine a situation in which a violinist with a fatal kidney disease has been artificially hooked up to you in order to use your kidneys for nine months. This has been done by the Society of Music Lovers and without your permission. If you unplugged yourself from this violinist now, he would die, and in that sense you would be responsible for his death. Inevitably, then, the moral question arises whether you are morally obligated not to unplug yourself from the violinist for the time being, even if this causes all sorts of inconveniences for you, such as staying in bed all day; after all, all “persons have a right to life, and violinists are persons . . . [and] a person’s right to life outweighs your right to decide what happens in and to your body.”[17]

This is Thomson’s main contention, and, even if somewhat bizarre, if the analogy holds which she is obviously drawing between the violinist situation and pregnancy, then the anti-abortion position would suffer a severe setback. However, it turns out that there is plenty of evidence to show that Thomson’s violinist analogy is in fact a false analogy and therefore fallacious and without rational force. To prove this, I shall now share several pieces of evidence that demonstrates that Thomson’s “Violinist” is in fact a false analogy.

First, the most obvious difference is perhaps that by unplugging the violinist, one would not engage in direct killing but in letting die. The violinist would be killed by a disease, whereas the fetus is aborted by killing him actively or at least forcibly removing him from his natural place of safety. It would not be correct, therefore, to treat the two situations as equal or analogous, because the violinist has a disease which he would die of, whereas the preborn human does not and would die of active violence done to him.

Another important consideration is that the violinist analogy, if valid, only holds true for rape cases, that is, in cases where a woman has been forcibly impregnated against her will, since in the analogy you were actually kidnapped by the Society of Music Lovers, and it was involuntary therefore. However, as John T. Wilcox points out, “the title of [Thomson’s] essay is ‘A Defense of Abortion,’ not ‘A Defense of Abortion in Rape Cases.’”[18] Thus, it is misleading and inconsistent to use an analogy that could only hold for rape cases to argue for a position that does not restrict itself to allowing abortion in rape cases only.[19]

Another point is that the violinist incident is artificial, bizarre, and contrived, whereas pregnancy is the exact opposite—it is most natural and occurs all the time. It is, in fact, necessary for the propagation of the human race. Says Wilcox: “In Thomson’s essay we have something as universal and necessary [for reproduction] as pregnancy compared to something so rare it has never happened and perhaps could never happen.”[20] He then goes on to make the point that it is “at least arguable . . . that the moralities we have represent some ways of dealing with the realities and regularities of human life; and they may not fit well the irregularities and impossibilities.” Given that, he concludes that it is “plausible to regard [the two cases] differently from an ethical point of view . . . [since] what is appropriate for kidnapped kidney bearers and their violinist parasites might not be appropriate for mothers and the babes in their wombs.”[21] This objection, though perhaps not necessarily conclusive by itself, is something which should definitely be seriously taken into consideration when evaluating the strength of Thomson’s violinist analogy.

A fourth objection that may be raised to Thomson’s analogy is the fact that the two cases are disanalogous inasmuch as unplugging the violinist is in no way comparable to the methods used for abortions. While the different methods vary, they all involve a very cruel killing of the fetus, whether it be through cutting, suctioning, or intoxication. Yet, at no abortion during any point of gestation is the fetus given pain relief, even though the “centers necessary for pain perception develop early in the second trimester,”[22] and so justice would require at least an attempt to relieve fetal suffering, especially in late-term abortions, where “[f]orcibly incising the cranium with a [sic] scissors and then suctioning out the intracranial contents is certainly excruciatingly painful.”[23] The point here is not to be graphic, but to point out that there is a fundamental difference between such a procedure, which is artificial, deliberate, and unnecessarily painful, and unplugging the violinist, which is nothing other than letting him die.

These are just some of the objections one can raise against Thomson’s analogy of the violinist, though multiplying them would extend the scope of this paper. I think, however, that the above objections are illustrative of some serious insufficiencies in Thomson’s argument, such that they take away from it the persuasive force that it may appear to have at first glance.

There are, without a doubt, many more arguments in favor of abortion that deserve careful analysis and critical examination but that I cannot treat here. But whatever these may be, I wish to offer one last objection to the pro-abortion position in general, an objection which looks at abortion also from an epistemological point-of-view and resembles in a way Blaise Pascal’s famous “wager.” It is an argument similar to that developed by Peter Kreeft,[24] and it can be judged on its own merits, even if one were to leave all previous argumentation aside.

The argument is simply this. In the abortion debate, there are only four possible scenarios which could obtain, namely that (1) abortion is right and we know it; (2) abortion is wrong and we know it; (3) abortion is right and we don’t know it; and (4) abortion is wrong and we don’t know it. No other option is possible.[25] So let us suppose that (1) obtains. In this instance, abortion would be morally justified, and no problem could arise. However, we know that (1) is false, for, obviously, there is serious controversy about abortion, and hence we do not “know” that abortion is morally right. If one of the other three scenarios should obtain, however, then abortion would be morally wrong, for if (2) obtains, then abortion is murder; if (3) obtains, then abortion is criminal negligence; and if (4) obtains, abortion is manslaughter.

I should perhaps elaborate on (3). Suppose you are a truck driver, and while you are driving at night, you suddenly see in front of you what looks like a man lying on the road, although you are not sure that it’s a man, for it might actually be a dummy. From your view, you simply cannot tell. Would it be morally justifiable for you to run over this “person”? Clearly, the answer is no. The very fact that youdon’t know whether it’s a human or a dummy obliges you not to run over it in order to be on the safe side, and to do otherwise would be morally reprehensible. This is how we are to understand (3), that not knowing whether abortion is right or wrong when in fact it is right is still morally inadmissible, for the uncertainty obliges us to err on the side of life. Therefore, anyone who would argue for abortion on the premise that we just don’t know whether the fetus is a human (or person) or not, is clearly wrong, as such a premise warrants the exact opposite conclusion, namely, that abortions must not be performed.

Thus, this “quadrilemma” argument establishes that even if we ignore all other rational arguments, in three out of four possible scenarios, abortion is morally wrong. But this number—namely, 75%—is sufficiently high to warrant the claim that abortions ought not to be performed.

Given all of the above, I propose that abortion, at least as far as the criticized arguments from Warren’s and Thomson’s essays are concerned, cannot be morally justified. On the contrary, the traditional anti-abortion syllogism remains as intact as ever and retains its moral force. Since abortion involves human life (on both sides), it is a very serious issue and must be very forcefully and convincingly argued for—by both sides. The principle of non-contradiction requires that only one of the two sides of the issue is right, and, necessarily, the other must be wrong, very wrong. Again, then, in order to come to a resolution of this issue, the primary requirement is that we let reason, not rhetoric, be our guide to show us what is morally right and what is morally wrong. We must go wherever reason leads us, even if the conclusion be uncomfortable or inconvenient.

Defining Success: Assessing the Feasibility of Pig-to-Human Transplantation

Ololade Olakanmi, Grinnell College

Winner, 2003 essay contest

In light of the severe shortage of transplantable organs, scientists have been seriously considering using pigs as potential organ donors. In the past, pig-to-human transplantation was an idle hope, but with recent advances researchers have been able to develop this procedure into a potential therapy. However, the utilization of this procedure also begets a multitude of moral, ethical and biological dilemmas which must be addressed if animal-to-human transplantation is ever to become a clinical reality. In this essay I will enumerate and attempt to rationally reach a conclusion on many of the dilemmas that encircle the issue of cross-species transplantation. I will especially focus on many of the biological concerns. Furthermore, I will argue that before pig-to-human transplantation is implemented, the scientific community must agree on the degree of laboratory ?success? necessary for this procedure to advance into clinical trials.

Medical Decision-Making: An Evaluation of Three Models

Esther Warshauer-Baker, Dartmouth College

There are several models for medical decision-making within the doctor-patient relationship, and this paper discusses three of these models: paternalism, informed decision-making, and shared decision-making. I describe each model and give arguments for the plausibility of each. I conclude that each is problematic. Paternalism, the traditional model, is problematic because it relies on a false ideal of medical certainty, and it devalues patient autonomy. This becomes apparent when one examines medical decisions involved in prostate cancer diagnosis and treatment. Informed decision-making, while possessing the merit of valuing patient autonomy, is also flawed, because it limits the roll of the doctor to a technician and information source, and it calls for an impossible bifurcation between information and values. Shared decision-making is the ideal model for most medical decisions, especially those involving a great deal of medical uncertainty. However, by examining the problem of doctors providing antibiotics to patients who do not have bacterial infections, it becomes clear that shared decision-making is not always appropriate. Doctors may have non-medical incentives to prefer what patients prefer. Indeed, to develop a non-problematic model for medical decision-making, we must take into account the societal and structural context within which medical decisions take place

Ethics and Innovation in Surgery

Christine Bezouska, University of Pittsburgh

While IRB review of human subject research is well-established in academic medicine, oversight of technical innovation, especially in surgery, is not. The goal of protecting the interests of human patients and subjects is accepted; the best means to that goal is very much in dispute. Some authors assert that all innovation is essentially research, and should be treated as such. Others recognize a difference between innovation and research, but see a need to better understand the developmental processes involved in innovation. This paper considers the nature of clinical innovation in surgery, where technical innovation is particularly important. I examine two historical examples of surgical innovation, and propose that such innovations typically evolve through three distinct stages. These stages differ in the degree to which the surgeon is motivated by his or her care-giving duties, versus the desire to acquire new information. The ethical justification for innovation and the potential need for third-party oversight at each stage are derived from the fundamental trust relationship between physician and patient. Possible systems for regulating the dissemination of new technologies and techniques, including approaches currently being tried in other countries, are briefly considered.

Issues of Distributive Justice in the Canadian Health-care System

Joy Kellen, University of Calgary

The Canada Health Act promotes foundational principles of universality and accessibility of health-care for all Canadians. Contrary to popular belief, a systematic analysis of social determinants of health indicates differential access continues to exist. This paper considers the impact of distributive justice on access to health-care in the Canadian health-care system. Distributive justice is about equal respect for persons – being entitled to the same rights and services as all other citizens and services of greatest benefit offered to the least advantaged (Rawls 1993, p. 5-6). Cardiovascular disease is used as an exemplar to consider the impact of distributive justice within the Canadian health-care system. This system traditionally focuses on treatment of diseases such as congestive heart failure at point of failure, with hospitalization for surgical intervention or intensive medical therapy. This concentration of funding and resources on interventions poses ethical problems of availability and accessibility of care for individuals living in low income or poverty situations. Their inherent social exclusion limits their freedom of choice and autonomy, and subsequently their opportunity for referral to specialty clinics for assessment and treatment. Such realities beg the question: Are health professionals truly attempting to provide care for those with the greatest need?

Human Genetic Diversity and the Threat to the Survivability of Human Populations

Abstract

Recent advances in reproductive technologies, especially those that alter the germ-line, raise many ethical and theological concerns. I address one of the pragmatic ethical concerns, the potential loss of genetic diversity. Since genetic diversity has an inverse relation with the survivability of populations, it is necessary to have strong evidence that the implementation of these technologies will not threaten the survivability of human populations. An examination of the genetic diversity argument (GDA) and the possible models under which the technologies would be distributed (free market and state control) reveals that there is not strongly persuasive evidence regarding the effects on genetic diversity of the reproductive technologies on human populations. The only available method to produce the required evidence is through a very complex form of human experimentation. The type of human experiment that would produce the evidence is incompatible with present ethical codes of conduct. Therefore, any implementation of these technologies on human populations should be banned.

Through advances in reproductive technologies humans will eventually have the ability to utilize nearly fully artificial selection on human populations. These technologies raise many ethical and theological concerns. I will address one of the pragmatic ethical concerns, the potential loss of genetic diversity. Genetic diversity has a direct relation to the fitness and survivability of various species and populations; as genetic diversity decreases within a population, so does the fitness and survivability of that population. An examination of the genetic diversity argument (GDA) reveals that there is not strongly persuasive evidence regarding the effects on genetic diversity of the reproductive technologies on human populations. The only method available to produce the required evidence is through a very complex form of human experimentation. The type of human experiment that would produce the evidence is incompatible with present ethical codes of conduct. Therefore, any implementation of these technologies on human populations should be banned.

There are many emerging technologies that could potentially affect genetic diversity. These include genetic testing and screening, selective breeding, population control, sterilization, selective abortion, embryo testing and selection, sperm donation, egg donation, embryo donation, surrogate pregnancy, fertility drugs, contraception, cloning embryos, and germ line or somatic cell manipulation (Resnik 2000, 454). Each of these reproductive technologies affects the composition of the human gene pool by increasing or decreasing the frequency of different genotypes or combinations of genotypes (Resnik 2000, 454).

The germ-cell line, or just germ-line, constitutes a cell line through which genes are passed from generation to generation (World of Genetics 322). Germ-line therapy is often differentiated from somatic cell therapy, which is the alteration of non-reproductive cells. This distinction is not as clear as much of the literature supposes, but the problems with the germ-line/somatic cell distinction are beyond the scope of this paper. The focus of this paper includes the screening of embryos with the possibility of destruction of certain embryos, the modification of DNA (deoxyribonucleic acid) of early stage embryos through in-vitro fertilization (IVF), and the modification of parent gametes (Zimmerman 594-5). These technologies pose the clearest threat to genetic diversity of human populations.

Genetic testing and screening examines the genetic information contained in a person’s cells to determine whether that person has or will develop a certain disease, is more susceptible to certain environmental risks, or could pass a disease on to his or her offspring (World 305). Parents could subject themselves to testing to determine whether or not to reproduce based on the likelihood of their potential children inheriting their genetic maladies. Also, embryos can be subjected to testing and screening to determine the likelihood that the future individual will develop a genetic disease. From that information, parents can decide to destroy the embryo, alter the embryo, or leave the embryo unmodified and risk that the child will develop a genetic disease.

Germ-line gene therapy (GLGT) is germ-line manipulation on the genetic level in order to prevent genetic diseases in future persons (Richter and Bacchetta 304). The goal of GLGT is to treat human diseases by correcting the genetic defects that underlie the genetic disorders (Anderson and Friedmann 907). Therapy presents an alternative to destroying embryos likely to develop genetic disease by actually correcting genetic defects. Also available is the alteration of parent gametes in order to eliminate the possibility of passing on genetic disease to their offspring. GLGT allows for the alteration of either the early stage embryo or the parent gametes to prevent genetic disease. By either eliminating those genotypes that are likely to produce genetic disease or by altering the genome to actually prevent the genetic disease from developing, these technologies have great potential to affect the genetic diversity of a population.

Genetic diversity is the variety and frequency of different genotypes or combinations of different genotypes within a population. A population is a geographically, socially, or culturally linked group whose reproductive decisions affect those within the group. Genetic diversity is measured by genetic variability, which diminishes in a population when the number of different phenotypes or the number of different combinations of genotypes decreases. Since populations are composed of individuals that carry genotypes, individual reproductive outcomes affect the genetic variability within specific populations (Resnik 2000, 452). Genetic diversity provides the resource for phenotypic variation that is integral in determining the rate of evolutionary change in an environment. A population that lacks genetic diversity will be poorly equipped to meet environmental changes and demands (Resnik 2000, 452). The importance of genetic diversity is undeniable; the survivability of a population is directly related to genetic diversity.

While genetic diversity has no intrinsic value, genetic diversity has a clear instrumental value. Humans place positive value in genetic diversity as it promotes the extrinsic value of survivability. There is an ethical duty to prevent decreases in the genetic diversity of populations because of its importance in the survivability of those populations. Decreases in genetic diversity in populations are ethically undesirable because actions that reduce the survivability of the population are unethical.

The genetic diversity argument (GDA) starts from the fact that scientific and technological developments in the realm of genetics and human reproduction will greatly affect the genetic diversity of human populations. There are both pessimistic and optimistic versions of the argument. I will briefly describe both versions of the GDA.

The pessimistic version of the argument contends that the increased ability to control human reproduction will result in a loss of genetic diversity that will threaten the health and survivability of human populations (Resnik 2000, 451). This threat to health and survivability is due to a decrease in the populations’ ability to adapt to environmental changes and demands. In effect, these technologies have the potential to make the pool of available phenotypic traits limited enough so that human populations will not be able to respond to changes in environmental demand.

This version of the GDA warns that germ-line altering reproductive technologies will reduce populations’ gene pools and eliminate potentially useful genes. Genetic diversity provides a resource of these useful genes. Evolutionary change is blind and has no way to know which genes are useful, therefore it is potentially damaging to population survivability to eliminate genes of any sort. As Glenn McGee notes, “The point of the GDA is that human beings also have no way of knowing which genes will be useful in the future or in different environments” (cited in Resnik 2000, 456). For instance, genetically homogenous populations of corn face problems with blight due to lack of genetic diversity. Although human populations have an ever-increasing level of control over the environment, the pessimistic response still turns on the inability to determine which genes will be useful in the future.

The optimistic version of the genetic diversity argument contends that these reproductive technologies could lead to increases in human health and survivability resulting in an improvement of the well being of populations (Resnik 2000, 457). The basis for this response rests on the historical fact that advances in technology increase humans’ ability to control nature. The ability to control nature often leads to positive changes in the adaptability and survivability of human populations. The optimistic GDA relies on this historical fact and the seemingly obvious inference that the above technologies will increase the ability to affect the genetic diversity of human populations (Resnik 2000, 457). A commonly cited example of how genetic diversity can be increased with the implementation of such technologies is the incredible diversity of canines. Of course, there are important dissimilarities such as the explicit intention to increase phenotypic diversity.

A major factor in whether these reproductive technologies will increase or decrease genetic diversity is what model they are implemented under, free market or state control. Each model addresses the concerns and motivations of those affected differently.

The free market model is based upon the reproductive decisions of a diverse group of potential parents with separate interests, motivations, and means. The free market is the method by which many consumer decisions are made in the United States. This model is fundamentally based on the interaction between supply and demand. If a market demands diversity of a product, then the market will often supply the desired diversity. If the market demands the standardization of goods, such as building supplies, then that homogeneity is likely to be supplied. Also, markets create new preferences and demands by introducing new goods and services to the market. Most often, advancements in technology increase market variability, except of course if that development results in the formation of a monopoly.

The diversity of goods in the free market system of America seemingly justifies the inference that a free market model for reproductive technologies would lead to increases, not decreases, in the genetic diversity of human populations. Both J. Glover and W. Gardner’s individual studies conclude, “Increases in our ability to control human reproduction will result in more genetic diversity in the human population because parents will have a variety of preferences and values that they can use in selecting offspring” (cited in Resnik 2000, 458). Just as technological advancements have increased the availability of diverse consumer products, germ-line altering technologies could increase the available options in reproduction and therefore increase the diversity of human populations. Nevertheless, confounding factors such homogeneity of desirable characteristics makes the above inference much more dubious than it first appears.

The major problem with the free market model is the potential emergence of the homogeneity of desirable characteristics. Many characteristics such as intelligence, athleticism, and health, are almost universally accepted as desirable. Other characteristics such as height, eye color, and hair color, also have particular value attached to them. Genetic homogeneity could arise if the consumers of reproductive technologies have similar preferences for traits. As Resnik states, “If most people want tall, intelligent, healthy children with blonde hair and blue eyes, then parental choices could produce a phenotypically and genetically homogeneous population” (2000, 459). This problem is only exacerbated when one considers the phenomenon of fads. Societal pressures and obligations may also produce conformity. While these social effects may not take hold immediately, it seems possible, if not probable that these pressures would eventually affect reproductive decisions. Genetic homogeneity may be an unintended consequence of a population sharing common values (Resnik 2000, 459). If most people within a population have similar characteristic preferences and a desire to conform, genetic homogeneity is almost inevitable.

Of course much of this line of reasoning depends on genetic determinism, which is incredibly naïve and misinformed. Environmental factors often play a decisive role in which phenotypes are displayed. If certain desirable traits, such as intelligence or health, were strongly linked to environmental factors regardless of genotype, then the inference from individual choices to phenotypic characteristics would be dramatically weakened (Resnik 2000, 465). On the other hand, if certain genes or series of genes are linked to a trait, and that genotype is most frequently selected, it would still poses the potential threat of a genetically homogeneous population, although not phenotypically homogeneous.

There are good reasons to believe that the free market system will create greater genetic diversity within human populations. On the other hand, the influences of societal pressures and expectations should not be underestimated or ignored (Resnik 2000, 459).

State control involves the local or federal government dictating the standards of practice in certain industries, such as the power industry, education, and mass transit. This model of control in implementing genetic technologies appears likely to lead to decreases in genetic diversity within a population. It is imaginable that the government would develop specific standards to which all human beings produced in that state would be subject. The effects of state control of reproductive technologies are not clearly predictable. A state controlled system could lead to a genetic caste system. For instance, if the state determined that all people should be a certain height, weight, IQ, color, sexual orientation, etc., then those who diverge from those state determined standards could be forced into different strata of the genetic caste system. Such scenarios are certainly plausible, if not likely under state controlled conditions.

Under free market conditions, reproductive technologies could lead to increases or decreases genetic diversity. On the other hand, state control would almost inevitably lead to decreases in genetic diversity, but the extent of such effects is not clear. As David Resnik claims, “the consequences of not exerting social or governmental control over human genetics may be just as troubling, since parents will in all likelihood attempt to provide their children with genetic advantages, and the long-term results of parental control over human genetics may further exacerbate existing social and economic inequalities and create a genetic caste system” (1997, 428). The inability to produce definitive evidence of the effects of reproductive technologies under either control model points to urgency of the issue and the minimal knowledge of these technologies’ implications for the future of humanity.

Each version of the GDA provides ground for arguments that could support or undermine the utilization of germ-line altering reproductive technologies. The most obvious conclusion from examining both versions is that there is no definitive evidence that implementing the above technologies will have positive or negative consequences for the survivability of human populations. Furthermore, an examination of the two most plausible options for methods of implementing the technologies within a population does not produce strong evidence that implementation will result in either increases or decreases in genetic diversity. This leaves medical science at an ethical crossroads between either continuing with the technologies and dealing with the results afterwards, or abstaining from research, or at least clinical trials, until such evidence arises. Neither of these paths seems to be positive, or even tenable.

The only method for producing clear evidence about the potential threat to survivability that these reproductive technologies pose would be to continue research and perform a massive clinical trial. Animal experimentation is not a viable alternative to human experimentation because it completely eliminates many of the confounding factors such as social influences. Since the arguments on either side of the GDA cannot produce conclusive results, and given the potential harm done to populations if the reproductive technologies are implemented and genetic diversity does decrease, some form of human experimentation seems necessary before the technologies should be implemented. Of course, there are many questions that arise in response to such a claim, including the justification of the inference to the necessity of human experimentation. I will discuss these concerns below.

To clarify the inference, one should be reminded of what is at stake with respect to genetic diversity. The cautionary tales of the GDA describe potentially analogous situations, such as the effects of artificial selection on the survivability of maize and the variety of canines that have been produced by artificial selection. It is not at all clear what effects the above reproductive technologies will have on a population’s genetic diversity. Their implementation could result in increases in disease susceptibility like the result of artificial selection on maize, or it could result in populations with incredible arrays of genetically distinct individuals, such as in the canine example. What is clear though is that genetic diversity has an inverse relationship with the adaptability and survivability of populations. Since human populations value their own survivability, it is clear that technologies that pose a great potential threat to genetic diversity should be closely examined before being implemented. Due to the great potential threat these technologies present to humans, it is necessary to produce very strong, if not definitive, evidence about the effects of these technologies on genetic diversity. The only way to produce such evidence is human experimentation.

There are many factors that must be accounted for in a human experiment that would produce definitive evidence. The number and diversity of subjects would have to emulate a population that would be affected by the technologies. The experiment would have to be extensive enough to determine the effects on future generations. To account for potential homogeneity of desirable characteristics, the experiment should account for both diverse cultural and societal pressures. Furthermore, the experiment should be carried out under the two control models mentioned above, free market and state control. Also, there would have to be a method of curtailing influences from the non-experimental population. Finally, in the event that something goes awry with the experiment, there must be a method of destroying the test subjects.

Given present ethical standards concerning human experimentation, the ethics of such an experiment are, at best, deeply problematic. While ethical norms can dramatically change with time through changes in societal norms and beliefs, the means necessary to employ such an experiment are almost incomprehensible. For instance, it is not at all clear how the experiment would quarantine the subjects or how to handle the necessity of multiple generations of researchers. The role of informed consent is unclear with such an experiment. In the proposed experiment, an unethical researcher could use informed consent in a manner to produce the results that the researcher desires and undermine the purpose of the experiment. Additionally, an integral part of informed consent is the ability to withdraw from the experiment at any time. This element could pose a serious problem for this type of research. Therefore informed consent must either be eliminated or be drastically altered. Under present ethical norms it is clear that the kind of experiment necessary to provide strongly persuasive evidence of the effects of germ-line altering reproductive technologies would be unethical. Ethical considerations aside, the pragmatics of such an experiment are daunting to say the least.

The use of germ-line altering technologies should not be implemented until strongly persuasive evidence regarding the effects on genetic diversity is concretely established. Decreases in the genetic diversity of a population would put at risk the survivability of that population. Humans place a clear value in the survivability of populations. Therefore anything that threatens the survivability of populations is unethical. Germ-line altering reproductive technologies may potentially decrease genetic diversity within a population. Until there is concrete evidence demonstrating that such technologies will not lead to decreases in a population’s genetic diversity, those technologies should not be utilized. The only method of assessment to produce such evidence is through human experimentation. The nature of the necessary experimentation involves unacceptable ethical violations and unavoidable pragmatic difficulties. Without strong proof that such technologies do not pose a threat to genetic diversity, and therefore population survivability, those technologies should not be implemented. Due to the fact that such evidence is not possible, germ-line altering technologies should be banned.

Considering the Use of Cost-Benefit Analysis in Biomedical Ethics

Sahar Akhtar, Duke University

Winner, 2003 essay contest

The field of bioethics, as with most areas of applied ethics, is laden with propositions about the intrinsic value of life, treating persons as ends in themselves, and bestowing priority to individual rights and autonomy. These ideals are important because they signify a society?s unwillingness to promote the common good at the expense of the individual. They also place emphasis on values, in particular respect for autonomy, that have historically been undervalued by various health-care practices. Furthermore, they offer goals to which to aspire. On the other hand, these values must also be vulnerable to evaluation, criticism and comparison with other significant values. Although this may seem obvious to some, few authors in the bioethics literature seem to fully appreciate the implications of the condition of scarcity. This is something which economists have taken seriously enough that they have built the condition into theories, both individual-based and public-based. Given that resources and time are both limited, we are often, indeed, always according to some views, forced to choose between competing values, claims, and preferences. However, economists are sometimes too quick to accept that trade-offs must be made, and a result of this may be that the ?costs? of adopting any one choice, which may be other significant values, are too easily written-off as being unavoidable. Both approaches seem to be incomplete in an important way. I argue that the requirement of trading off one value for another needs to be taken more seriously in bioethics. In addition, though, I also argue that there is the simultaneous need for identifying what would be intrinsically and absolutely valuable under ideal conditions?that is, in a world of abundance.

Education as a Basic Need

Karen Hornsby, Bowling Green State University

The claim is often made that education is a universal right. Yet rarely is support offered for this claim. Certainly there are consequentialist reasons for a society to educate its citizens. But are people entitled to an education; is education a right? In an attempt to answer this question, this paper will examine a basic needs approach to education. First, I will discuss the concept of a basic need. I will argue that in modern society education is necessary for decent life prospects?for people to avoid a blighted or seriously harmed life?and thus education is a basic need. Next, I will analyze if basic needs produce rights claims. After addressing several challenges to a general needs to rights argument, I will argue that basic needs generate positive rights. In order for all people to have effective opportunities to obtain a basic education, some positive action is required. Finally, I will consider who is responsible for the correlative duty of satisfying an educational right. My contention is that the reciprocal duty to unmet basic needs rights cannot be satisfactorily addressed through charity or citizens acting individually and is therefore, a duty which falls to the state.

The Moral Case for Scientists as Advocates for Environmental Policy

A current issue in the area of environmental ethics concerns the role of scientists as advocates for environmental policy.  This raises two distinct and complex ethical issues.  The first is the effect that scientists and their expertise can have on environmental policy issues.  The second is the evaluation of the scientists themselves.

In this paper I will give some background about the first issue as it relates to conservation biology.  Conservation biology offers a somewhat unique test case of the effects scientists can have on policy issues, since, in its very conception, the field of conservation biology is interested in policy issues as well as scientific research.  Additionally, it is worthwhile to note up front that this first ethical issue is not the main focus of this paper.  While interesting and important, I am here more concerned with the ethical issues that advocacy itself raises for scientists, rather than specific concerns about what effect scientists can have on policy issues.

The second issue, about advocacy itself, is the main focus of this paper.  I will argue that it is morally permissible for scientists to be advocates for environmental policies.  This is for three reasons.  First, since scientists are also citizens, it is improper to deny them the opportunity to advocate for things they think are important.  ”Citizenship” here does not refer to citizenship in any particular country. Since environmental concerns are global concerns, citizenship in the global community is all the citizenship that is required to make this claim.

Second, scientists, who do possess at least some expertise in the area of environmental policy, should be sought out to advocate for these positions precisely because they the ones with the knowledge, understanding and access to objective studies relating to policy issues.  Some scientists will be better equipped for this than others, as some areas of scientific research are more relevant to environmental policy than others.

Third, I will argue that that while objectivity is required for scientific research, advocacy for policy issues does not entail a failure of objectivity.  Further, it seems that to contrast advocacy with objectivity is, in some sense, mistaken.  Those who contrast advocacy with neutrality have, perhaps, located a better contrast, but to suppose that scientists should be neutral about all things is also mistaken. One last point on this issue is important to make now.  Scientists who do not engage in objective research and who try to use that research as support for positions for which they advocate may be successful in the short run, but, as their scientific research is exposed, will ultimately be unable to serve as good and credible advocates for the positions and policies they care about.  This point is related to the first issue as well.  Those scientists who do this are not only poor scientists, but also poor advocates.

The Effect of Scientists on Environmental Policy

Conservation biology is somewhat of a unique discipline to examine in light of policy issues.  It is so, because, as a discipline, it wears its values on its sleeve, so to speak.  As Bryan G. Norton writes in his editorial for the journal Conservation Biology entitled “What is a Conservation Biologist?” “conservation biology is a prescriptive science … [and has] a social obligation to participate in the public debate about the nature of ecosystem health” (Norton 1988:237).  Norton also says “conservation biologists must participate with the public in the debate regarding the very nature of ecological health, even while trying to protect it.  This responsibility must be accepted squarely; [this] fledgling discipline must not hide behind a false façade of value-free science” (Norton 1988:238).  Railing against the view of positivistic science as he does, Norton identifies conservation biology as a scientific discipline with values.  Norton is himself a conservation biologist.  And while scientists are often thought to subscribe to the positivistic view of science, Norton is not alone among his colleagues in conservation biology in renouncing it.

In 1996 the journal Conservation Biology ran a symposium on the role of advocacy in conservation biology.  In its introductory piece Reed F. Noss claims that advocacy in conservation biology is how the field expresses its public responsibility, that “few conservation biologists today claim that science in general or [conservation biology] in particular is value-free” and that “although viewpoints differ, most contributors [to the symposium] believe that the role of values and advocacy in conservation biology is central to [the] field” (Noss 1996:904).  The main piece of the symposium, “A Science for Survival: Values and Conservation Biology” by Dwight Barry and Max Oelschlaeger argues that conservation biology is “inescapably normative,” “ethically overt,” and that “advocacy for the preservation of biodiversity is part of the scientific practice of conservation biology” (Barry and Oelschlaeger 1996:905).

So, what does this mean for the effect scientists can have on environmental policy?  In some sense, only very little.  It does mean that some, perhaps most, conservation biologists see advocacy for at least maintaining biodiversity as one of their responsibilities as conservation biologists.  But as Barry and Oelschlaeger admit, as well as James E. Salzman in “Scientists As Advocates: The Point Reyes Bird Observatory and Gill Netting in Central California” admits, scientists can have either a positive (understood as protecting biodiversity) or negative effect on environmental policy.  What effect scientists have on policy depends on many things such as reliability of scientific research, willingness of policy makers to listen to them and understand scientific data, the gravity of the problem requiring policy intervention, etc.  And while scientific data is often critical to the decision-making process for policy makers, this does not ensure that scientists or scientific data will have a positive effect on policy.  Salzman notes that one thing that led to scientists and scientific data having such a positive effect in the Point Reyes case was that long-term studies done were seen as objective and presented in that light by those who, even though they had a vested interest, were seen as doing objective research (Salzman 1989:173).  Those involved in advocacy for policy in the Point Reyes case were seen as keeping their advocacy role separate from their research and this went along way with the policy makers.

Martin Wachs in his paper “Ethics and Advocacy in Forecasting for Public Policy,” argues that those who produce studies specifically for policy makers are too often at the mercy of those policy makers and frequently provide studies with less than credible results.  Advocating for policies in this situation, Wachs argues, removes researchers from the pure research that they are best suited for(Wachs 1990:143).  Wachs’s paper addresses others than scientists as well, such as traffic planners, for example.  He does highlight one very important thing, although it may not be completely obvious in reading his paper.  His main criticism is of those studies produced specifically for advocacy purposes.  It is less clear how his remarks should be taken when examining research done for research’s sake and only later put to use in advocacy.  Some conservation biologists, such as Tracy and Brussard basically agree with Wachs’s assessment and argue that this is taking the science out of conservation biology to the detriment of the discipline (Tracy and Brussard 1996:918).

Given that it seems intuitively clear that things can have a positive result given advocacy’s effect such as in the Point Reyes case, or negatively as Wachs discusses, we have a more important question to address.  What parameters are required for scientists who wish to engage in advocacy that will help ensure a positive result (as much as that is possible given that there are many other actors involved) and ensure that they also fulfill their responsibilities as scientists?  One interesting point that the Point Reyes case brings to the forefront is that good science makes for good advocacy.  This question will only be partly answered here as I argue that scientists are morally permitted to be advocates for environmental policy.  The way scientists engage in advocacy is limited by what is morally permissible, but this is true for all those who engage in advocacy as well.

The Moral Permissibility[1] of Scientists as Advocates for Environmental Policy

The first argument in favor of the moral permissibility of scientists serving as advocates for environmental policy is really quite a simple and intuitive one.  While environmental policies are usually taken country by country rather than internationally, the environmental crises that policies are intended to address are global ones.  In some sense, as frequent reference to the “butterfly effect” reminds us, there really is only one ecosystem.  Since the environmental issues at hand are global ones, members, citizens[2] if you will, of the global community have a vested interested in resolving those environmental crises in a way that is to the overall, long-term benefit of the members of that community.

Members, or citizens, of the global community, as those with a vested interest in the resolving of environmental crises, should be morally permitted to act in ways that ensure, or help to ensure, that the necessary policy changes to resolve these crises are made.  It seems clear that morality is intended for the benefit of at least the global community here on Earth.  And, as such, supports the advocacy of scientists.[3]

Given that the default position[4] here is to permit members of the global community to act in these ways, or rather, to advocate for policy change, scientists, who clearly are members of the global community, ought to be permitted to advocate as well.  To exclude scientists from those permitted to advocate requires a strong, positive argument.  The burden of proof clearly rests on those who wish to limit what seems otherwise to be a prima facie moral right.  Rather than leaving it like that, let us consider two possibilities for such an argument, and in so doing discuss the two remaining points.

One might think that scientists ought to be excluded from having this right of advocacy because they might hold too much sway in policy debate given their scientific knowledge and expertise.  This kind of argument might be likened to why many jury experts encourage lawyers, when picking juries, to exclude other lawyers.  A lawyer on a jury panel might use his or her knowledge of legal proceedings to sway others on the jury in an illegitimate way when the jury is deliberating.  But it seems that the analogy does not hold with the case of scientists advocating for policy decisions.  Legal knowledge is not required for analyzing the evidence in a trial – the judge instructs the jury as to what they are to consider.  But scientific knowledge is required for making informed environmental policy. A scientist, such as a conservation biologist, is in a better position to analyze, interpret and understand scientific data in support or against some environmental policy.  Perhaps then, his or her view on the matter should be given more weight than someone’s view who is not in such a position.

In the specific case of a discipline like conservation biology that is clear and upfront about its values and goals, we can figure out why a conservation biologist endorses some policy over another.  This helps us determine what weight to give to such an advocate.  If our goals or values do not include biodiversity and ecosystem health, then it seems we should discount a conservation biologist’s advocacy, but if they do include those things, the view of a conservation biologist should be weighted heavily, given his or her expertise. Note that how we weight the data is a matter of what our goals and values are, not whether it is a scientist or a layperson advocating for a position.  So, rather than excluding scientists from the role of advocate, we should encourage them, as it aids, not hinders, informed policy decisions.

It seems clear then, that the expertise of a scientist is not the kind of thing that ought to take him or her out of the running for being an advocate for environmental policy.  To do so, strips a member of the community of a moral right, which is illegitimate without strong justification.  Advanced knowledge does not count as justification for such a position.

Some might think scientists should be excluded from being advocates because becoming an advocate will compromise their abilities as scientists.  This is one of the most frequently given arguments against scientists as advocates, and one sometimes given by scientists themselves.  There really are two different issues that are intertwined in this one.  First is whether the claim is true.  Is it in fact the case that advocacy on the part of scientists entails a lack of objectivity in their scientific research?  The answer to this, I think, is clearly “no.”  The second issue is whether the contrast that is cited between advocacy and objectivity is really proper and what we should be focused on.  I believe that the contrast is a mistaken one and I will address the problems with the contrast with neutrality that has been suggested as a replacement for the contrast with objectivity.

Scientific objectivity is hailed as a cornerstone for scientific research.  Without getting into questions about scientific paradigms and normal science, we can take objectivity in science to mean that science and the research that is a part of it is conducted in ways such that illegitimate bias is excluded from the scientific method and scientific results.[5] One way this point is often expressed is by saying that the scientist does not care how the experiment comes out.  Strictly speaking, this is false.  Researchers do care how experiments come out, whether their hypotheses are confirmed or denied.  The point, rather, is that an objective scientist will not manipulate data from experiments to support some hypothesis over another.  Lynn Maguire, also a conservation biologist, says that she thinks that making values clear in conservation biology will expose some bad science as untrustworthy but also show that much of conservation biology is done in such a way as to “yield results that, viewed in the context of values do provide a trustworthy basis for advocacy” (Maguire 1996:915).

Setting aside the fact that objectivity is itself a value in science, dispelling the myth of a value-free science, the idea that advocacy entails a lack of objectivity falls flat.  If objectivity is something like what I have proposed above, there is nothing in the concept that is necessarily compromised by advocacy on a related issue.  The information is not necessarily compromised because it came from an advocate.

I suppose that some might think there is a problem if one takes the catch-phrase of “not caring how things turn out” to be the definition of “objectivity” and takes advocacy to mean that one cares about some outcome.  But first it is important to note that the catch phrase is strictly speaking, false.  Second, even if it were not, the care that is being expressed in the catch phrase for objectivity and for advocacy is not care about the same thing.  For objectivity, it is about the results of an experiment, and for advocacy it is about some state of the world, expressed through some policy or something like biodiversity, for example.

What this demonstrates is that one way of making the case that objectivity and advocacy are incompatible is really mistaken.  On one reading as I have suggested, it is based on a misunderstanding about the objects involved in each of the concepts, through having a poor analysis of the concept in the first place.  This should serve as a warning about using “catch-phrases” rather than clear definitions or accounts of the concepts involved in an argument.

Given that it seems that advocacy does not entail a lack of objectivity, it seems there is no reason to exclude scientists from being advocates.  It may be true that advocacy and objectivity are linked.  Some advocates may lose their objectivity, but being an advocate does not necessitate this.  Further, being objective in one’s research might encourage advocacy!  If one finds in one’s research something unexpected and disturbing, one might be induced to do something about it.  This very kind of occurrence is what leads many scientists to fields like conservation biology (Barry and Oelschlaeger 1996) and (Lovejoy 1989).  Often such scientists cite the love of nature as the reason they got into science in the first place, and they think it odd that later, as a scientist, they should be required to set aside that love.[6] Further, that love of nature would be ill-served if the research were not objective, as it would prevent them from doing what was best for nature, as is mentioned in Section I.  This is, of course, not to say that some are not misled by that love, rather, that being mislead is not necessary.

The second point is whether it is objectivity that really ought to be contrasted with advocacy in the first place.  And, it seems, not really.  Kristin Shrader-Frechette discusses the idea that objectivity, which is what is wanted in science, is not achieved by neutrality(Shrader-Frechette 1994:181-182).  In some sense then, it is neutrality that ought to be contrasted with advocacy.  Environmental advocacy, she says, is “taking a stand on a specific, practical issue and defending that stance as rational and ethical rather than merely pointing out the assets and liabilities of alternative positions, rather than merely maintaining a stance of informed neutrality” (Shrader-Frechette 1994:179-180).

This suggestion, that it is neutrality and not objectivity that ought to be contrasted with advocacy, is an interesting one.  First, it is interesting since it suggests that the traditional dichotomy has it wrong.  Second, it is interesting because if it is neutrality that is the correct thing to contrast with advocacy, we can show that objectivity is a scientific virtue, while neutrality is not.  So, even with this contrast to advocacy, we can still, and perhaps more clearly, argue for scientists being advocates.

Objectivity requires that, as a scientist, one lets the facts speak for themselves.  It demands that research be conducted without prejudice and reported without bias.  This means that the scientist must, in order to be objective, “represent indefensible positions as indefensible and less defensible positions as less defensible” (Shrader-Frechette 1994:182) just as the scientist must represent defensible positions as such.  Any interpretation of the data that might be done should be done with the values and commitments of the scientific method in mind, and nothing else.  This does not mean that science is subjective in a negative sense, or has abandoned its purposes and goals.  It is clear to most that positivism in science is either inappropriate or false.  The pursuit of scientific knowledge is committed to some values, at least to methodological values, such as objectivity.  This entails that the old idea of science as value-free is simply mistaken.  Looking at how objectivity and neutrality differ will show that this is so.[7]

Neutrality requires that we make no such value commitments, not even methodological ones.  And this flies in the face of good science.  Neutrality, seen under the positivistic view of old, suggests that “all values deserve equal respect” (Shrader-Frechette 1994:182).  But even if it is not ethical values that are at issue, science simply cannot endorse such a view.  We would think it was absurd to give up a commitment of repeatability in science because we were supposed to pay equal respect to non-repeatability. Neutrality, then, is not a scientific virtue, since it would commit scientists to positions that would prevent or severely hinder the pursuit of scientific knowledge.

Given that neutrality is not a scientific virtue, while objectivity is, the positivistic view that they are one and the same is shown to be false.  Being left with objectivity and not neutrality, the conclusion to draw is the same as given above – that scientists ought to be allowed to be advocates for environmental policy.  The moral permissibility of this seems clear, although given much confusion in the discipline, confusion among policy makers and governmental agencies, and an old-fashioned view of science, which attempts to hide its value commitments, it has often not been clear at all.

This is not to say that the moral permissibility of scientists as advocates does not come with responsibilities.  Scientists, when acting as advocates, have responsibilities, perhaps greater than the average advocate.  Scientists have responsibilities because whether they like it or not, they are in a position of public trust.  Advocacy under that circumstance becomes much more complex, and while interesting, I do not have time to go into that in depth here.  Scientists who wish to exercise their moral right to advocate must be very careful in their scientific duties as to avoid charges of bias or partiality.  Still, it is possible to do this – there are at least, no conceptual barriers.

To recap, briefly, conservation biology is a good science to look at for this discussion because it is, in a very real sense, a normative science.  Its values are forefront in its scientific pursuits.  Presenting the normative values of a genuine scientific discipline is a first strike at the view that science is value-free, which is often a cornerstone for those arguing that scientists should not be allowed to be advocates.  I then argued that scientists, as citizens of the global community have a moral right to serve as advocates for policy issues. Two reasons some might think they ought to be excluded are (1) scientists might have too much sway in environmental policy decisions and (2) it will compromise scientific research.  These were shown to be illegitimate reasons for preventing scientists from being advocates.  First, scientific knowledge is required for making policy decisions and second, scientific values need not be compromised by advocacy.  To conclude, reasons offered for preventing scientists from exercising this moral right are not persuasive, as they are often grounded in misunderstandings.  Scientists should be morally permitted to be advocates for policy issues they feel strongly about, but also must be careful so as to remain credible scientists.

[1] Some, such as Kristin Shrader-Frechette, have argued that there are situations in which scientists are required to be advocates (Shrader-Frechette 1994) and(Shrader-Frechette 1996).  I will not argue for this stronger position here.

[2] Science and citizenship are discussed directly by Meine and Meffe in 1996. “Conservation Values, Conversation Science: A Healthy Tension.”Conservation Biology 10 (3):916-917.

[3] This is the case even if one does not think that the environment or ecosystems has intrinsic moral standing, since a healthy ecosystem is instrumentally valuable to humans.

[4] I suppose that this “default position” is informed by the western liberal tradition, so some may have objections to it on those grounds.  However, it seems unlikely that this would be someone’s main objection.  Even so, it still seems right to me to say that there are some basic moral rights, which include things like speaking out in favor of what one thinks is morally correct.  Presumably, one thinks that policy change in favor of biodiversity and ecosystem health, as in the case of conservation biology, is at some level, a moral position.

[5] I say “illegitimate bias” because some bias present in research is legitimate.  For example, if doing an experiment on frogs, I ignore that I got the frogs for the experiment from a company in Michigan rather than one in Virginia, I have excluded something irrelevant.  This kind of bias is required for objective research.

[6] On a personal note – I have a friend from my time at Colorado State University who joined the Philosophy MA program after leaving the MA program in the Department of Entomology.  He left that department when they changed their name to the Department of Pest Management.  He said that he got into entomology because he loved bugs – not because he wanted to “manage” them.

[7] Shrader-Frechette has offered six reasons to think that objectivity does not equal neutrality.  See (Shrader-Frechette 1994:182-183).
