SCS, NRCS, and the future As aggressive (but truly rea-

Ethical Land Use: Principles of Policy and Planning. By Tim- othy Beatley. 300 pp., 1994. The John Hopkins University Press, 2715 Charles Street, Bal- t imore, M D 2 12 18-43 19. $17.95 paperback, $55 hard- cover.

Ethical Land Use is a book which champions an argument that needs to be made, and Timo- thy Beatley has done an intelli- gent, thoughtful, and thorough job. His book examines the ethical dimension of land use, focus- ing in particular on the steward- ship of the nation’s natural environment-not only the plains, wetlands, coastlines, and forests but also the air and water, as well as life, both sentient and nonsentient, which comprise the natural ecology. The book consid- ers, to a somewhat lesser extent, aspects generally associated with urban areas, such as architectural aesthetics and even adult-oriented land uses as they relate to the ethical dilemma between community values and individual freedom of choice. Beatley’s approach is in- terdisciplinary and makes master- ful use of learned sources repre- senting perspectives that are variously philosophical, religious, economic, legal, political, and of course, ecological. (The bibliography and citations make an excep- tional research resource.)

Any book is a medium between the author and the reader, and as such, it is subject to the context in which it is read almost as much as when it was written. As Ethical Land Use is being perused by this reviewer, i t has been only six months since the Republican takeover of Congress and a scant month since the bombing at Ok- lahoma City. These events have forced the national consciousness, and that of the reviewer, to recog- nize the dissatisfaction which a substantial number of the Ameri- can populace feel-and even an abhorrence harbored by a radical few-against what many perceive

as unfettered growth of government and its unwarranted regula- tory intrusion into private rights.

Thus while I can envision most readers of the Journal of Soil and Water Conservation nodding in happy agreement with Beatley’s viewpoints and advocacy, which I also applaud and largely share, I am haunted by the realization that many-and arguably a voting majority of Americans-may not subscribe to those views, at least at this time. When the 104th Con- gress is at the verge of amending the Endangered Species Act and the Clean Water Act with crip- pling property-rights amend- ments, and when elected officials in some rural communities are characterizing the Bureau of Land Management, the Forest Service, and the Fish and Wildlife Service as enemies of the people (or “normal Americans” as the Speaker of the U.S. House might suggest), the question might be asked: whose land use ethic is the Ameri- can ethic, and more pragmatical- ly, whose ethic is to prevail as the basis for policy and planning?

I applaud Beatley’s thorough- ness and fairness in his up-and- down-and-all-around airing of viewpoints, whether or not con- gruent with his own. But as he noted in his preface, he does “in- termix [his] own values and perspectives into the discussion;” (p. xiv) and consequently, as with any advocate, his citations are necessarily selective to further his own cause. Given the probable reader- ship of the book, however, Beat- ley’s efforts may be somewhat like preaching to the choir, since ad- herents of opposing views would scarcely be swayed by his scholarship, however factual and meticu- lous. Unfortunately, rationality and reason do not necessarily equate to evangelical persuasive- ness. Happily, however, nature is often its own best champion. The evocative experience of an incom- ing summer storm on a Colorado mountaintop, the discovery of a redwood cathedral in California,

or simply a reading of Thoreau can almost always do more to per- suade one of the environmental ethic than any intellectual analysis however substantive. Indeed it could be said that the persuasive- ness of Leopold, Carson, and McHarg lay more in their power as poets than as naturalists.

Beatley’s book cites English scholars contemporary to Ameri- can history whose writings con- tributed to the ethical foundations of this nation’s society, notably John Locke, whose work was popular and influential in the era leading to the American Revolu- tion, and John Stuart Mill, the nineteenth century philosopher, whose views are discussed fre- quently in the book. As Beatley recognizes, Locke’s teachings es- tablished much of the ethical ra- tionale behind the prerogatives of private property which were fun- damental in the minds of men such as Jefferson and Washing- ton-men revered in American history as secular saints for their leadership in the War of Indepen- dence and the penning of the Constitution, but who were prag- matic men of property and business as well.

Recognizing Locke’s funda- mental influence in establishing the prevailing Jeffersonian regard for property rights in America, Beatley’s thesis is constrained only to diminish Locke’s theories are “unrealistic” and “heavily criti- cized.” (p. 192) While consideration of Locke is virtually unavoid- able in any credible assessment of the philosophical underpinning behind the American ethic of private property, Beatley scrupulous- ly avoids mention of other writers whose influence at the time of the nation’s inception were even more popular and intense in their de- fense of private property: Sir William Blackstone, who asserted private property to be “that sole and despotic dominion” of the owner (but apparently not the William T. Blackstone cited in the bibliography and text), and

Adam Smith, the author of the “invisible hand” metaphor of lais- sez-faire market determination, surely the leading nemesis of environmental planning and protection.

Beatley’s discussion of the work of J. S. Mill is appropriate in that this nineteenth-century English philosopher took a more moder- ate position than the fire breath- ing proponents of private property of the earlier century (whose views were then shaped by domes- tic quarrels with the British Crown, of which the American Revolution was a colonial out- growth). But even Mill’s utilitari- an views focused on the welfare of the individual first, and only then on the community good as the empirical outcome of that priority. (This characteristically English view contrasts with the primacy ascribed to the community collec- tive by the German rationalist philosophers, notably Karl Marx, whose views are-needless to s a y-an t i t h e t i cal to American thinking.)

Again Beatley’s reference to Mill is selective, since he avoids mention of another English philosopher, Herbert Spencer, whose influence in America at the turn of the century was notably greater than Mill’s. Spencer’s con- cept of Social Darwinism-some might say a perversion of nature’s “survival of the fittest” (Spencer‘s terms, not Darwin’s)-made Spencer the darling of American capitalists (Carnegie and Rocke- feller) and presidents (Taft). Nor does Beatley mention William James, the native American author of the philosophy of pragma- tism, an outlook of potentially disastrous implications for planning and environmental conservation. By contrast, Beatley’s more contemporary philosophical icon, John Rawls, and even J. S. Mill are of tangential political influence in shaping the prevalent America ethic toward society, much less nature.

Americans of all political per-

suasions have been ingrained since childhood to regard the nation’s Constitution as a near-sacred document that embodies the ethical dimensions of God-ordained natural law, although certainly some believe in a more fundamentalist interpretation than others. In this prevailing political-cultural context, Beatley’s reference to international conventions, however reasonable, as ethical grounds for environmental conservation may seem somewhat self-defeating, es- pecially at a time when some citi- zens, for their own reasons (myth- ical black helicopters and sabotaged road signs among them), regard international orga- nizations from the United Na- tions to the TriLateral Commis- sion with suspicion and even outright fear and loathing. For such people, to encompass more broadly the “normal” and reasonable majority who voted for a more conservative Congress in the last election, the question would be, “Whose ethic underlies Ethical Land Use?”

To argue that American society should reassess the ethics of its use of land is a formidable undertak- ing indeed, for ethics have an intrinsic cultural and religious dimension. Considering the predominant Christian heritage of American society and Beatley’s ci- tation that “Christianity is the most anthropocentric religion the world has seen” (p. 2O), American culture is indisputably anthropocentric (although the anthropo- morphic deities of ancient Greece, which were antecedent to the Western value of a humanized religion, show a cultural precursor that was certainly no less so). Other religions which have been characterized by the West pejora- tively as heathen or pagan have decidedly greater intrinsic regard for the natural world. As Beatley points out the Amerindians are known for their reverence of natural spirits. Likewise, the Taoist regard for nature is well displayed in Chinese landscape paintings. (While this artistic expression dates to the first millennium BC., by comparison, Western landscape art did not appear as a genre until the nineteenth century.) Certainly there is no suggestion that America forsake its main- stream Christian-Western heritage to embrace instead the Amerindi- an ethic. And as Beatley correctly points out , i t is questionable whether such a religious culture

could better conserve the environment if population sizes and den- sities under such an ethic were conceivably comparable. (p. 190)

O n a more practical level, a corollary to the question, “whose ethic?” is, “who is to pay?” This question is related to the issue of NIMBY or “Not In My Back- Yard (an argument made by Jack Kemp’s U.S. Department of Housing and Urban Develop- ment in a government document which is predictably cumbersome but nonetheless a respectable counterpoint to Beatley’s book). Who then is to pay for Ethical Land Use! Not likely the environ- mentalist nor the college professor, but rather the families and communities whose livelihood and housing prospects may be threatened or at least diminished by landuse regulation. (On more than one occasion I have heard planners admit privately that they would not want a necessary but disruptive LULU [or Locally Un- wanted Land Use] in their own backyard either.) Is it fair (or ethical) to ask one party to pay the price for another’s sense of ethics? As in the abortion debate, another issue also fraught with ethical dilemmas, restrictive public poli- cies are easy-and even right- eous-for the policy makers, but typically tough on the policy make-ees. Is there really much dif- ference in principle between the protests, “Get your laws (and religion) off my body!” and “Get your laws (and ethics) off my land!”?

What happens here to the cur- rently fashionable ideal of democ- ratic citizen participation? And if a municipal vote is exclusionary, as to protect a locality’s environment and values by keeping out low-income housing, what happens to the excludees and their rights? Beatley writes that “the principle of maintaining and pro- tecting the natural environment should take priority over [socially] distributive obligations where they are in direct conflict.” (p. 120) Interestingly enough, the plaintiffs in the famous Petaluma and Mt. Laurel court decisions were a housing development association (the environmental “bad guys”) in the former and the NAACP (the civil-rights “good guys”) in the latter. T o this reviewer at least, the issue is not so simple that any one party should be accorded unwavering priority.

Over the last few months, the

polemics between environmental protection and the protection of property rights have come to the national forefront with both fac- tions claiming ethics to be on their side. So the question is, “whose ethic?” Perhaps my only criticism of Beatley’s book is the title, which implicitly makes moral claim to “Ethical Land Use” without qualification. (I also no- ticed the masthead mission of the Soil and Water Conservation So- ciety is to advocate “wise use” of natural resources. Notwithstand- ing, there is another group that claims the same title as their own, but with a decidedly opposing doctrine of ethical and “wise use.”) So is ethics an absolute?

As I stated at the outset, Beat- ley’s book makes strong arguments in support of an indisputably wor- thy cause. He writes that his “in- tent is to inject new substance and life into the land-use debate” (p. 262). The thoughts that his book has provoked in this reviewer are proof at least of his successfbl realization of this goal. As one who is perhaps too inclined to view both sides of an issue and then to play the devil’s advocate, I admire Beat- ley’s scholarship and applaud his heartfelt advocacy. Ethical Land Use is a book that should be read by all believers in ethical and wise use of land, however construed.

The author identification section of the manuscript Ancient Maya terracing and modern conservation by Timothy Beach and Nicholas Dunning was incorrectly printed in the March-April 1995 issue of JSWC. It should have read as follows:

Timothy Beach is an assistant professor of geography and environmental science in the School of Foreign Service, George- town University and Nicholas Dunning is associate professor of geography at the University of Cincinnati . They have worked on the environmental aspects of several different archaeology projects in the Maya Lowlands, including the project discussed in this paper: The Petexbatlin Regional Archaeology Project, codirected by Arthur Demarest, Vanderbilt Universi- ty, and Juan Antonio Valdez, San Carlos University, Guatemala. Funding for this research was provided by the United States Aid for International Develop- ment, the Swedish International Develop- ment Agency, the National Geographic Society, and the National Endowment for the Humanities. Many other Petexbath Project members are partially responsible for the data reported here, including Robert Chatham, Oswaldo Chinchilla, Lionel Paiz Diez, Stephen Hous ton , Thomas Killion, David Rue, Estuardo Se- caira, and Dirk van Tourenhout.
