The Ideal of Nature: Debates about Biotechnology and the Environment
()
About this ebook
Drawing on philosophy, religion, and political science, this book asks what the term “nature” means, how it should be considered, and if it is—even in part—a social construct. The contributors question if the quality of being “natural” is intrinsically valuable. They also discuss whether appeals to nature can and should affect public policy and, if so, whether they are moral trump cards or should instead be weighed against other concerns.
Though consensus on these questions remains elusive, this should not be an obstacle to moving the debate forward. By bringing together disparate approaches to addressing these concepts, The Ideal of Nature suggests the possibility of intermediate positions that move beyond the usual full-throated defense and blanket dismissal found in much of the debate. Scholars of bioethics, environmental philosophy, religious studies, sociology, public policy, and political theory will find much merit in this book’s lively discussion.

The Ideal of Nature - Gregory E. Kaebnick
Preface
A wide swath of contemporary social debates features what might be called appeals to nature
—claims that nature or a natural state of affairs possesses some special value that should be weighed in moral decision-making and perhaps protected in public policy. These appeals are of a variety of kinds and involve many different understandings of what nature
means. While none of them fit easily into the classical accounts of moral values in Western moral philosophy, they have enduring power in everyday moral discussion and, recently, somewhat wider acceptance in the scholarly literature, giving them significant clout in a range of contemporary social debates.
Perhaps the most prominent of these debates is over what humans may do to themselves and to others—from the kinds of relationships they may form with each other to the biotechnological interventions by means of which they can actually change their own or their children’s bodies. Concerns about which human relationships are natural
have a long history rooted chiefly in religiously oriented natural law traditions; however, a range of commentators have recently developed concerns in a more expressly secular fashion about how biotechnology might change the very categories of nature, including the category of human nature. The President’s Council on Bioethics, formed by President Bush in August 2001 to address the ethical and policy ramifications of biomedical innovation, argued against a variety of biotechnological alterations of human bodies and human practices on grounds that the changes would be dehumanizing
(President’s Council on Bioethics, 2003). From a very different political perspective, the environmentalist Bill McKibben followed up his book The End of Nature with Enough, which lamented that human genetic engineering and other technologies will bring about the end of human nature
(McKibben, 2003). The communitarian political philosopher Michael Sandel argues that the deeper danger
in using gene transfer technologies to enhance ourselves or our children is that doing so represents a Promethean impulse
to remake nature, including human nature, that inappropriately elevates human willfulness and mastery (Sandel, 2007, pp. 89ff.). It is widely (though certainly not universally) held that athletes should not be permitted to use performance-enhancing drugs. And people of a variety of viewpoints hold that we should die natural deaths, not planned ones carried out with a doctor’s assistance, and not ones indefinitely postponed by means of tomorrow’s antiaging
technologies.
Another category of high-profile social debates that feature appeals to nature concerns other species. This category includes debates about agricultural bio-technology and what might be called pet biotechnology
—such as the development of a fish, originally created for industrial purposes but now marketed as a pet, that glows red or green in the dark. These appeals to nature are frequently subordinated to other moral concerns, that agricultural biotechnology will have bad environmental consequences or bad consequences for human health and well-being, for instance. Much of the argument against genetically modified corn, for example, focuses on whether it might kill off monarch butterflies. The language in these debates, however—coining terms such as Frankenfood
and Monsatan
(playing on the name of the company, Monsanto, a leading producer of genetically modified seeds)—suggests that those opposed to biotechnology think the problem is something ungodly, something reminiscent of Dr. Frankenstein. At times the appeal to nature emerges openly. Some European philosophers have argued, for example, that genetically modifying chickens to become insentient egg producers would unacceptably violate their species integrity,
even though it would benefit humans and possibly even chickens (Bovenkerk, Brom, and van den Bergh, 2002). When the California Fish and Game Commission decided to ban the Glo-fish,
one commissioner told a reporter with the San Francisco Chronicle, At the end of the day, I don’t think it’s right to produce a new organism just to be a pet. What’s next? A pig with wings? … Welcome to the future. Here we are, playing with the genetic bases of life
(Martin, 2003).
In recent years, some argue, the tools and information available for genetically modifying organisms have progressed to the point that the goals have grown much more ambitious and the very identity of the field has changed. Instead of making just a few genetic modifications to existing organisms, and doing so in a largely trial-and-error fashion, we can aim to synthesize entire genomes, then to design basic, simplified genomes and an assortment of genetic parts,
as it were, that code for particular biological functions and that could be assembled in various combinations and installed in the genome. The product of this genetic construction would be a synthetic organism, and the work of producing it has been dubbed synthetic biology.
The near-term goals of synthetic biology are microbes specially engineered to produce medicines or fuels. Still, the question has been raised whether in going from genetic modification to synthetic biology the human relationship to nature has changed from ‘manipulatio’ to ‘creatio ex existendo’
(Boldt and Müller, 2008).
When the argument against agricultural biotechnology rests on a concern about its effect on the natural world, it may amount to an indirect appeal to nature, for the environment is the focus of a third category of debates involving appeals to nature. As in debates about agricultural biotechnology, appeals to nature in environmental disputes take the form of claims about what is natural for nonhuman entities, in this case about the patterns and diversity of species, wildernesses, ecosystems, and other natural phenomena. If debates about medical biotechnology involve claims about human nature, and debates about agricultural biotechnology involve claims about nonhuman nature in human settings, then environmentalism is about nonhuman nature in isolation from human beings.
In the environmental domain, unlike debates about animal and medical biotechnology, appeals to nature have clearly led to policy. The Endangered Species Act of 1973, for example, arguably presupposes that species ought to be preserved for their own sake—or, more accurately, that species ought to be protected from human endangerment for their own sakes and allowed to go extinct only through natural causes. Many of the species in whose interests the act is invoked do not provide significant benefit for humankind—not enough to outweigh the benefits of the hunting, fishing, logging, or recreational activity that threatens them. The anger and indignation environmentalists feel about species loss seem to reflect an underlying concern about the species themselves, a sense that it is simply wrong, at least in the absence of strong countervailing considerations, to cause naturally occurring forms of life to disappear from the world. Likewise, the Wilderness Act of 1964 appears to presuppose the intrinsic value of spaces that are, in the language of the act, untrammeled by man.
If they are untrammeled, then relatively few people are directly benefiting from their preservation, and the moral rationale for their preservation seems to lie in something other than human benefit. Again, in the debate over logging old-growth forests, the problem with logging them all cannot be just the loss of a valuable resource: not to log them is also to lose the resource. Similar impulses may lie behind the creation of the federal national park system.
A Comparative Examination of Appeals to Nature
A spate of scholarly and popular books, reports, and articles has advanced arguments of one sort or another about appeals to nature, but sustained comparative studies that take on the entire range of appeals to nature are rare. Instead, these writings have tended to remain within the confines of a particular subject—environmental ethics, where nature
is central to debates about what should be protected (or sometimes, restored); agricultural ethics, where the concept of nature
has been invoked and criticized in debates about genetically modified crops and livestock; and bioethics, which includes issues of medical biotechnology and its use to enhance human nature. This volume of essays, emerging from a three-year research project conducted by the Hastings Center and funded by the National Endowment for the Humanities, tries to advance thinking about nature
in a more broadly comparative fashion. The project took up the three broad social debates identified above—about human nature, about domesticated organisms, and about the preservation and protection of the environment. The essays in this volume have more to say about human nature and the use of medical enhancement—the Hastings Center’s home turf—than about the other topics, but all of them are informed by other debates, some engage in explicitly comparative work, and as a group they seek to set work in other domains, especially concerning the environment, alongside work in bioethics.
Three broad questions animated the project. The first is a question of conceptual clarification: What does nature
or natural
mean? What are the similarities and differences across different social debates in how the idea of nature
is deployed? The second is a question in moral philosophy: If a state of affairs is natural, can its being natural ever have any moral significance? Can its being natural be valued for that reason alone, not merely because it helps show how to achieve some other morally valuable end? Do the different uses of nature
function similarly? The third question moves from moral to political philosophy: May appeals to nature affect public policy? If so, are they moral trump cards, or should they be fitted in alongside or weighed against other moral concerns?
Consensus is almost unimaginable on these questions, and the contributors to this volume do not seek it. The goal is rather to turn the issues in the light for a while. Some of the contributors return to and refine the critique of nature
that goes back to John Stuart Mill. Others look to defend appeals to nature. Among those that attempt a defense, however, opinions cluster in suggestive ways—revealing not a consensus, but at least a constellation of related opinions, and perhaps opening up promising avenues for further work.
With respect to the first, conceptual set of questions, for example, a theme linking several chapters is that while nature
and human nature
elude clear definitions, clear definitions may also not be necessary. Several papers also consider the possibility that the concepts of nature
and human nature
can be considered in relatively narrow and metaphysically modest ways. A couple of papers explore the possibility that nature
might refer only to the nature of a species rather than to a special essence
of a species or to a broad ontological distinction between what is natural and what is artificial. Several also consider the possibility that the understanding of nature might even be, in some part, a social construct.
Similarly, with respect to the second kind of questions—those about the moral significance of the natural
—several of the chapters defending appeals to nature explore the possibility that naturalness
might make only a limited moral difference. In particular, a distinction between natural and not natural need not point to a general distinction between permissible and impermissible to have moral significance. Instead of a general distinction, several papers propose, the distinction might be specific to a given context, such as sports. Or, following a line developed in some other papers, instead of outlining the limits of the permissible, appeals to nature might seek to ground only an attitude of humility or of respect and forbearance, not sufficient to prevent all human interference in natural states of affairs but enough to generate misgivings about frivolous destruction of nature.
The third set of questions, about the intersection of moral concerns with the political sphere, is taken up explicitly only toward the end of the volume, but again the theme is that a qualified, limited role can be allotted to appeals to nature. The connection between moral claims and public policy in a democratic society is more complicated than those who write mostly about the moral claims sometimes recognize. In many cases, this question, which is a matter of political philosophy more than of moral philosophy, is left unaddressed entirely. The assumption seems to be that if supporters secure the moral claims about appeals to nature, then the public policy will follow automatically. In fact, moral positions should not always be reflected in public policy, and when they do they might be reflected only indirectly—sometimes, for example, a democratically elected government should merely preserve the possibility that citizens can act on their moral positions, either individually or in private associations. In the case of sports, it might be accomplished (to at least some extent) by allowing decisions about policy concerning athletic enhancement to devolve to privately run sports-governing bodies. Also, as the last chapter in this volume argues, the regulation of biotechnological enhancement may sometimes fall outside the realm of basic social justice; when it does, the values to which regulators appeal may not need to meet the same standards for universal public acceptance that applies to matters of basic social justice.
Organization of the Volume
The chapters are organized roughly according to how they take up these three questions, with earlier chapters focusing on conceptual problems and later chapters bringing greater attention to moral and political concerns—although discussions in each chapter cut across all these questions to some degree. The chapters are also divided between those that consider older work in the Western philosophical canon on the moral relevance of nature and human nature, and those that consider contemporary problems invoking appeals to nature ; the more historically oriented chapters come toward the beginning of the volume.
In the opening chapter, Kate Soper discusses a range of social debates in which the concept of nature appears, and she introduces the problems and tensions inherent in deploying the concept and in jettisoning it. She endorses a certain skepticism about nature, arguing that attempts to clearly delineate naturality
are largely unsatisfying and that the concept of nature by itself is of little use in practical reasoning because whether something is natural does not by itself tell us what to do. At the same time, she underscores how difficult it is to exclude appeals to nature, and she observes that a flat dismissal of any way of understanding the concept would lead to incoherent idealism. She seeks to recapture a realist concept of nature,
which she argues is indispensable to the coherence both of ecological discourses about the ‘changing face of nature,’ conceived as a surface environment, and to any discourse about the genetically engineered or cultural ‘construction’ of human beings or their bodies.
Soper draws on a wide assortment of thinkers in the Western philosophical tradition. Chapters 2 and 3 continue this effort, looking for a defensible and nuanced concept of nature in historical resources. In chapter 2, Jean Porter argues that the early scholastic conception of natural law is relevant (surprisingly enough, she admits) to contemporary concerns about nature and the human relationship to it. The scholastic concept of natural law was friendly to the idea of nature and optimistic about the capacities of the human intellect to understand and appropriately value the natural world. Reflecting a robust philosophy of nature that began to emerge in the late eleventh century and a broadly expansive and open theology emphasizing the intrinsic intelligibility and goodness of the created order, the scholastic idea of nature points suggests new ways of thinking about human alteration of the natural world. It also, argues Porter, identifies possible common ground in the contemporary debate between religion and science.
In chapter 3, Bruce Jennings explores the role of nature and human nature in the early development of social contract theory—the dominant line of thought about social obligation and authority. Jennings argues that Hobbes and Rousseau gave discourse about human nature the fundamental place in their cultural theories. Their conception of nature, however, is independent of any metaphysic, cosmology, or theology and leaves it to human beings to construct cultural order without any transcendent pattern to follow—they assert that universal rational principles provide no definitive guidance; nor is there divine inspiration to be followed.
The next three chapters focus on how the concept of natural
is used in specific debates. In chapter 4, Gregory E. Kaebnick considers the concept of human nature
and asks what philosophical commitments about human nature are implied by a moral objection to altering human nature. He proposes that some positions require very well-developed and inflexible understandings of human nature but that others can be much looser, and even incomplete, contrary to what many commentators believe. In particular, he draws a contrast between positions requiring an essentialist
understanding of human nature and those that do not. In developing his argument, he sets out a taxonomy of positions on the concept of human nature and its moral significance.
Chapters 5 and 6 turn to the use of nature
in debates about environmental protection and preservation. Eric Katz offers the most unbending defense of nature
in the volume. He asserts that there is a real ontological difference between natural entities and artifacts and that nature
is a significant moral category for the development of public policy. Maintaining this distinction,
he argues, serves as a check on the arrogant notion that human power and human knowledge is unlimited, that human science and technology is capable of dominating and controlling the entire world.
Without it, he fears, we will awake one day to a fully humanized world. This will be a world of parks, but not of wilderness. It will be a world of playing fields, but not of meadows, a world of canals and waterways, but not of rivers.
In chapter 6, Steven Vogel offers a counterpoint to Katz, with a thorough rejection of the concept of nature.
Vogel argues for a postnaturalist
environmental philosophy—a philosophy after the end of nature.
He argues that it is needed because nature might already have ended and because we do not really know what nature is, or how and why to distinguish it from the human. The concept of nature
is so ambiguous and problematic, so prone to misunderstanding and so riddled with pitfalls, that its usefulness for a coherent environmental philosophy will turn out to be small indeed.
Katz closes his discussion of nature
by trying to extend his work, grounded in environmental philosophy, to questions concerning the human relationship to human nature. Chapters 7 and 8 carry this comparative challenge forward. Starting with the critique of nature
found in John Stuart Mill (a critique that also underlies Vogel’s analysis), Bonnie Steinbock sorts through a variety of contemporary ways of discussing the human relationship to nature. She argues that many influential contemporary conceptions of nature are inadequate, but she concludes that moral concerns about nature can have moral weight. Factual claims about nature can justify caution about the use of new technologies. Moreover, our humility and awe when confronted with the power and beauty of nature are appropriate and suggest that reducing nature to its commercial value is crass. We should feel gratitude for the natural world, Steinbock argues, but we should not blindly accept nature as a guide for our actions, nor should we reject something simply on the grounds that it does not exist in nature.
Paul Lauritzen writes about the idea of gratitude as well, but from a literary angle. He draws on the work of novelist Cormac McCarthy and essayist Wendell Berry to argue that the need to cultivate certain virtues, especially humility, often stands behind appeals to nature. Much of Lauritzen’s work has been on the use of medical biotechnology; in chapter 9 he broadens his focus to include agricultural biotechnology and environmentalism. Like Steinbock, he looks for a plausible, halfway position on nature
—a way of understanding the concept that gives it moral heft but does not turn it into an inflexible, overriding moral requirement. He writes that, at least in McCarthy’s and Berry’s thought, altering nature does not look to be intrinsically wrong, nor does it always generate unacceptable consequences. We should nonetheless attempt it only with a sense of caution and humility, acknowledging our ignorance and our misplaced pride.
Human enhancement in the context of sports provides useful case studies for thinking about appeals to nature. It also, as Nicholas Agar notes, could set a powerful precedent for appeals to nature in other domains. The concluding four chapters focus on appeals to the natural
in the context of sports, reprising all of the questions that have been broached in previous chapters. In chapter 9, David Wasserman offers a generally critical assessment of objections grounded in the concept of nature
to biotechnological enhancement of athletes. He argues that it is difficult to develop a coherent and morally defensible account of the natural
in sports and hard to predict how sports might be altered as enhancements creep in. He concludes that the concept of the natural
might yet be resuscitated as referring not strictly to a divide between natural and artificial but to one between different practices that either respect or violate the background conditions framing the way the competition is understood and the meaning and value it has for participants and spectators. Practices that respect widely accepted and well-established conditions are deemed natural,
and innovative practices that challenge these conditions, and may challenge the meaning found in the competition, appear to be unnatural.
In chapter 10, Agar argues forcefully for a restrictive stance toward human enhancement in sports. His appeal is to the interests of spectators. Spectators want to watch sporting performances that are not only exceptional but also produced by competitors similar to them in ways they care about. Performance-enhancing drugs and genetic modifications offend against this sense of shared humanity. Sports are a kind of drama, Agar suggests. To play Hamlet well, it is not enough to remember every line perfectly and enter and exit the stage on cue. One must convey Hamlet’s humanity to the audience.
Employing what he calls the common-sense morality
developed and deployed by Aristotle—an approach that focuses on examples, draws out concepts, definitions, and principles as possible but accepts, if necessary, fuzzier demarcations and family resemblances—William Galston attempts in chapter 11 to show how the distinction between therapy and enhancement can be useful in thinking through the ethics of human enhancements. Although the distinction does not permit one to draw a line between what is permitted and forbidden, it points to a structure of justification.
Enhancement serves goals, Galston argues, whose validity and importance must be assessed case by case. He develops some presumptive principles about which kinds of performance-oriented enhancements are justified and which are not.
The volume concludes with a discussion of sports enhancement that considers, at length, the political significance of appeals to nature—specifically, the place of appeals to human nature in a Rawlsian framework. Thomas H. Murray and Peter Murray argue that John Rawls’s theory of justice not only carves out a space in moral and political debate for ideas about human nature but also serves as a model for how to generate conceptions of human nature that could serve as normatively important ideals. They argue that John Rawls, unsurpassed philosopher of justice and lover of baseball,
helps us understand the place of sport and of the concept of natural talents
in a liberal society.
Although the scope of the volume is very broad, many interesting topics are not addressed in it. For example, the relatively new topic of synthetic biology, mentioned above, is not expressly treated, although general categories of questions raised here—about how the concept nature
is understood, whether and how that concept legitimately figures in moral discourse, and whether and how moral discourse about it legitimately figures in political discourse—are all relevant for thinking about synthetic biology. Synthetic biology raises these questions in a particularly fundamental form, since it broaches the related conceptual question What is life?
and the related moral question What is the proper human relationship to life?
Even supposing that humans may modify existing living things, the further question arises whether they may create entirely new forms of life, as some strands of synthetic biology seek to do. There are also reasons for thinking that synthetic biology poses less of a challenge to the human relationship to nature than some other kinds of interventions, including genetic modification (of crops and livestock), on which synthetic biology is a technical advance. Synthetic biology is not yet about crops and livestock; it is only about microbes—not exactly the most charismatic of species and not at the forefront of most environmentalists’ concerns. Discussing synthetic biology would require an examination of the particular way it raises concerns about the human relationship to nature; nonetheless, the essays here should at least provide a leg up with that further work.
The very old topic of sex—the original synthetic biology, perhaps—is also not treated. The questions at the intersection of sex, nature, and morality are various, of course. They include, for starters, questions about sexual relationships, familial and other relationships between the sexes, the role of sex within the family, and the implications of artificial reproductive technologies. Again, the three general categories of questions broached here are relevant, but again, particular issues would also have to be taken up. For example, to talk about sexual relationships, it would not be enough to know generally how to handle the concept of nature
; we would also need to have a lot of information about what actually is natural. There are important factual questions at stake—more than could be adequately handled in this volume. Additionally, we would have to consider whether it is general types that we are interested in or individual cases. That is, would a belief that the human relationship to nature is morally significant translate into a belief that statistical norms about human beings generate value norms to which people ought to try to conform, or is the point rather that we ought to cherish even natural diversity? This point is taken up briefly in Kaebnick’s essay.
Some ways of thinking about nature
are also left out of the volume. For example, although several of the discussions emphasize Aristotelian reasoning, an extended discussion of Aristotelian lines of thought is not included. Nothing in the volume draws exclusively on religious traditions either. The deep ecology
movement, whose adherents argue that nature has an especially strong kind of intrinsic value (significant in its own right, rather than merely as a way of achieving other ends, and existing independently of whether anybody recognizes that value) is also not represented. To some degree, these omissions reflect the fact that the volume comes out of two meetings held at the Hastings Center in 2006 and 2007. In some cases, they also reflect a decision to concentrate on perspectives that try to avoid relatively extreme or narrowing metaphysical commitments—claims about the nature of the cosmos, that is, that make that perspective interesting chiefly within a particular tradition. The goal has been to think about moral attitudes toward nature within a secular and fairly mainstream space of reasons and to think critically but constructively about what might be said about them. What has emerged is a predictably wide range of opinions, but within that range an intriguing constellation of positions that defend appeals to nature. These positions are united by the loose theme that there might be qualified, limited ways of understanding appeals to nature that allow them to play a role in individual moral positions, and perhaps even in public policy, but do not carve out a decisive role for them.
