Essay Leopold Aldo The Land Ethic

Wallace Stegner

Daniel Boone's reaction [to the outdoors] depended not only on the quality of what he saw, but on the quality of the mental eye with which he saw it. Ecological science has wrought a change in the mental eye. It has disclosed origins and functions for what to Boone were only facts. It has disclosed mechanisms for what to Boone were only attributes.... We may safely say that, as compared with the competent ecologist of the present day, Boone saw only the surface of things...


1) "Land" (which we would now call an "ecosystem") is a system of interdependent parts: best regarded as a "community," not a "commodity."


In a strict sense, I submit that the analytic philosophers are correct: it is a basic rule of logic that one cannot validly introduce into a conclusion terms and concepts that are absent from the premises. Accordingly, one cannot derive "oughts" from "is-es," values from facts, prescriptions from descriptions. Philosophers have come to call such attempts "the naturalistic fallacy."


This maxim, ignored throughout most of the history of Western civilization, has recently become common knowledge. It has echoed throughout the world, even within the walls of the Kremlin, as Mikhail Gorbachov proclaimed: " , ... ." "Humanity is part of the biosphere, and ... the biosphere is an integrated whole."

A fanciful thought experiment might illustrate the difficulties with such an approach. Suppose our bodily organs were conscious and deliberative. One might imagine a "selfish kidney" saying, "look, why should I care about the heart and lungs? Me and my buddy kidney have our own problems?" To which the heart might respond, "Oh yeah? If that's the way you feel, I'll just do my thing and the Hell with you?" Needless to say, you wouldn't want to be carrying a life insurance policy on that body.

While the concept of the "healthy land" is implicit, and occasionally explicit, throughout A Sand County Almanac, Leopold takes little trouble in either defining this concept or defending its desirability.

But why should the systemic 'health' of the ecosystem be of interest to the human beings? Because, of course, our personal health is inextricably tied in with the health of the ecosystem. We'd better take care of the ecosystem if we know what's good for us. But that's simply anthropocentrism writ large. And, of course, Leopold wants much more than that: not mere "enlightened self-interest," but affirmation and love. For, as Joseph Wood Krutch writes, in behalf of Leopold: "We must live for something besides making a living. If we do not permit the earth to produce beauty and joy, it will in the end not produce food either... Unless somebody teaches love, there can be no ultimate protection to what is lusted after."

... the best environment is one in which the human animal can have maximum contact with the type of natural environment in which it evolved and for which it is genetically programmed without sacrificing the major advantages of civilization... Every basic adaptation of the human body, be it the ear, the eye, the brain, yes, even our psyche, demands for proper functioning, access to an environment similar, at least, to the one in which these structures evolved through natural selection over the past 100 million years.

It is an intriguing hypothesis, to be sure, and not without some nagging problems. How, for example, are we to explain such notorious naturophobes as Ronald Reagan's Interior Secretary, James Watt, and that quintessential urbanite, Woody Allen? Despite such puzzling counterexamples, I suggest that there is at least something to the hypothesis -- that, to use Paul Shepard's vivid image, the destruction of nature is an "amputation of man."

It remains to be determined just how much we can live in a totally artificial environment, detached from the environment that selected our genes and shaped our genome, without going bonkers. I will only suggest that amongst those genes that hard-wire our nervous system, are a few that dispose us toward having positive "natural sentiments" of affirmation toward undisturbed nature, and conversely, to suffer when deprived of our primeval landscapes. From this "biophilic" nervous system has issued the great works of art, literature and science that celebrate nature. Beethoven's "Pastoral Symphony," Debussy's La Mer, Van Gogh's Starry Night, Thoreau's Walden, Ed Abbey's Desert Solitaire, Sigurd Olson's The Singing Wilderness, and, of course, Aldo Leopold's A Sand County Almanac -- all are voices of nature speaking back to us and through us.

The wisest, the most enlightened, the most remotely long-seeing exploitation of resources is not enough, for the simple reason that the whole concept of exploitation is so false and so limited that in the end it will defeat itself and the earth will have been plundered, no matter how scientifically and far-seeingly the plundering has been done.

To live healthily and successfully on the land, we must also live with it. We must be part not only of the human community, we must acknowledge some sort of oneness, not only with our neighbors, our countrymen and our civilization, but also with the natural as well as the man-made community.

"Ecological thinking," writes Holmes Rolston, "leads us to silent wonder and affirmation."

As authentic lovers, we cherish nature, not for ourselves, but for its own sake. Thus do we affirm the "health of nature," as a good for ourselves. The ethical foundation of the Land Ethic is thus complete.

The enduring strength and significance of Leopold's work lies in the fact that his literary grace and his philosophical vision are grounded in hard and compelling science: ecology. Through this science alone we may gain understanding -- all too often, coldly and impersonally. Add moral philosophy and we might literally comprehend (meaning "bring together," "encompass") and appreciate the facts, laws and theories yielded by science. Leopold's Land Ethic transforms the science of ecology into a world-view, and thus the grounds for a guide to conduct -- which is to say, an ethic. "That land is a community is the basic concept of ecology," he writes, "but that land is to be loved and respected is an extension of ethics."

As it happens, Leopold was not simply out of step with his philosophical contemporaries, he was ahead of them. And now, at last, moral Philosophy has caught up with him. As few philosophers would or could recognize in the thirties and forties, ethics cannot be reduced to simple emotions or acts of will of the individual. For to seek "meaning" in ethics from such a perspective makes as much sense as the statement, "move that horse-head piece two squares forward and one square left," detached from knowledge of the placement of the other pieces, and of the rules and objectives of the game of chess. Now we have come to realize that moral philosophy must be grounded in an "ecology" of relationships, expectations, sentiments, and requirements, so that, as the ecologist Garrett Hardin puts it, "the morality of an act is a function of the state of the system."

In fact, the progress of the Almanac, from particular observations at his Sauk County farm, to generalizations from his North American travels, to "the Upshot," his summary concepts and precepts, is built, not upon controlled experiments and structured arguments, but upon anecdotes and impressions. Accordingly, to those who fail to understand Leopold's method and grasp his objective, Almanac is weak science and unrefined philosophy.

Not bad for a Wisconsin professor, who claimed he was just writing for himself and his friends, as he jotted down his sketches sipping coffee by "the shack," while the dawn crept across the meadow of his farm.

17. In an unpublished earlier version of the Foreword to A Sand County Almanac, Leopold wrote: "These essays were written for myself and my close friends, but I suspect that we are not alone in our discontent with the ecological status quo."

Critical response



In his essay “The Land Ethic,” from A Sand County Almanac, Aldo Leopold confronts the weaknesses in the common approach to conserving the environment. His proposed solution is no less than the development of an entire new branch of ethics to guide humanity’s relationship with the natural world. It is a big idea. Leopold carefully explains every aspect of his reasoning to us, from a brief history of ethics, to what it means to live in a community with the land, to why it is necessary to do so. But in the end, when we are waiting for him to break down his moral code explicitly, he vaguely concludes: “A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise” (224–225). We may come to the end of the essay in total agreement with Leopold but still not understand what we should do. What specific things should we do differently if our actions are to be ethically just? The confusion is further complicated by Leopold’s claim that “the biotic mechanism is so complex that its workings may never be fully understood” (205). If we cannot understand our environment, how can we know what behavior will preserve its integrity?

Leopold often emphasizes in “The Land Ethic” how hard it is to understand the workings of nature and our role in them. He describes the land—the plants, animals, water, and soil of our world—as “the community clock” (205), a mechanism, or an “energy circuit” (217). Putting it in these terms highlights the land’s delicate, interdependent organization. The biotic community, he writes, “is a tangle of chains so complex as to seem disorderly, yet the stability of the system proves it to be a highly organized structure” (215). Like a clock, each tiny piece performs a vital function. Tinkering with a clock is a job that can only be done effectively by a skilled and experienced craftsman. But, as Leopold points out, humans have tinkered with the land to the effect of radical changes to its structure. The clumsy changes man makes to his environment “have effects more comprehensive than is intended or foreseen” (218). Since we only see the cause and effect of our actions in hindsight, we cannot know with confidence that the actions we take toward the land today will turn out to be ethically right or wrong. Leopold warns us: “Conservation is paved with good intentions which prove to be futile, or even dangerous, because they are devoid of critical understanding either of the land or of economic land-use” (225). When we don’t understand what we do, we’re at risk of destroying the integrity of the biotic community. We may even destroy ourselves. It is this fearsome uncertainty that creates our need for more concrete instructions from Leopold, but he cannot give us a list of rules because of that same uncertainty. Leopold doesn’t know how to fix the biotic clock. Without a deep understanding of its mechanics, any rules he might lay out could just as easily result in disaster. But then what kind of ethic can we have?

Ultimately Leopold is asking us, since we cannot know how to live in perfect harmony within the environment, to try to limit our effect on it. It is there in the word “conservation” itself: conserve the land. Don’t let it go to waste; keep it from changing. Leopold understands that change inevitably occurs within the energy circuit, “but it is a sustained circuit, like a slowly augmented revolving fund of life” (216). He sees a balance that happens with gradual, natural change, and this is one of the system’s strengths. He acknowledges that degree of flexibility in the structure as he writes: “When a change occurs in one part of the circuit, many other parts must adjust themselves to it” (216). The trouble with our role in this perfectly engineered machine is that we are increasingly able to make enormous changes to the circuit very quickly. In Leopold’s time, the process was beginning to accelerate. The Industrial Revolution and World Wars brought humanity into the modern era. Leopold saw that man was now able “to make changes of unprecedented violence, rapidity, and scope” (217). Looking at where we are now, 64 years later, that potential has increased exponentially. How much more complex and unknowable, then, are the ultimate consequences of our modern way of life on the land? Is Leopold asking us to abandon it all and return to the wilderness?

No, he is calling for a philosophical shift rather than specific actions. Early in the essay, Leopold mentions the Mosaic Decalogue, better known as The Ten Commandments (202), and the Golden Rule (203) as examples of ethics. Both ethics guide our relationships with individuals and society, but there is a distinction between them that illuminates what Leopold’s land ethic is intended to be. The Ten Commandments is exactly what its name suggests: a declaration of ten specific moral rules that are literally set in stone. The Golden Rule, on the other hand, is a single guiding principle of reciprocity: treat other people the way you would like to be treated. While the Ten Commandments ask only to be obeyed, the Golden Rule requires active reflection. To know how to treat others, we must think about feelings and consequences and give true consideration and respect to another human being. There is no point-by-point instruction set handed down by a higher authority. Instead, it is a deeply personal attitude and way of thinking that can shift and evolve with different situations.

Leopold intends for his land ethic to be developed in that same spirit. Throughout the essay, he stresses that, “The evolution of a land ethic is an intellectual as well as an emotional process” (225), and it “reflects a conviction of individual responsibility for the health of the land” (221).  In contrast, he complains that the conservation efforts of his day are little more than a formula: “obey the law, vote right, join some organizations, and practice what conservation is profitable on your own land; the government will do the rest” (207). For Leopold, such a formula is too simple to be effective. Meaningful progress is accomplished in a different way:

No important change in ethics was ever accomplished without an internal change in our intellectual emphasis, loyalties, affections, and convictions. The proof that conservation has not yet touched these foundations of conduct lies in the fact that philosophy and religion have not yet heard of it. In our attempt to make conservation easy, we have made it trivial. (209 – 210)

Leopold wants to change humanity’s soul right down to its foundations. Rather than having his essay give us a “trivial” list of “easy” steps we can take to conserve the environment, he wants to inspire us to take the land community into our hearts, the same way we try to take the human community into our hearts. Leopold believes the land deserves the same considerate treatment we give to our loved ones: “It is inconceivable to me that an ethical relation to the land can exist without love, respect, and admiration for land and a high regard for its value” (223). We humans often do not understand each other and can easily hurt one another, but we try to bridge that gap in understanding with thoughtfulness. When a conflict arises, we reflect on it, try to see what went wrong, and use its lessons in our future interactions. What we should not do is use or manipulate each other unthinkingly. We can apply these same principles to the land community. There are things about the land that we don’t fully comprehend, and that ignorance can result in negative consequences. But with the attitude of the land ethic, those situations can become teachable moments that yield deeper insight and better ways of living. Human history is already full of such moments we can study. Leopold asks: “Is history taught in this spirit? It will be, once the concept of land as a community really penetrates our intellectual life” (207).

So even once we understand why Leopold’s land ethic is so vague, another question remains: has it penetrated our intellectual life? Does the essay succeed in communicating Leopold’s subtle concepts? It’s easy to assume that the best way to convey an idea is to say it directly and clearly, but Leopold works in a different way. We end “The Land Ethic” with questions still stuck in our heads. How do we make the land ethic a reality? How do we know that our actions won’t create ecological disasters? These questions are seeds of thought that Leopold planted. So we keep thinking about them and, as we do, the seeds grow in our minds. That is what Leopold would call “the stirrings of an ecological conscience” (221). And that was what Leopold wanted: not to give us easy answers or tell us what to do, but to inspire generations of conservationists to think deeply about our relationship with the land.
