The Great Heretics

Tribute to Garrett Hardin

"In every age," writes Bronowski (1973), in The Ascent of Man, "there is a turning point, a new way of seeing and asserting the coherence of the world." Similarly, Abraham Lincoln (1862) said, "As our case is new, we must think and act anew. We must disenthrall ourselves . . ."

It seems clear that the great forward leaps of human progress have been made by people who "disenthrall" themselves and develop "a new way of seeing and asserting the coherence of the world." We see this in Galileo and Copernicus, who had the audacity to claim the earth was not the center of the universe. We see this in Charles Darwin, who took on the religious establishment with the heretical idea that man was a product of evolution. We see it in political systems where Locke and Jefferson had the revolutionary ideas that humankind could govern themselves. We see it in Freud with his upsetting idea that man was not always a rational animal. All of these people challenged the current ordained wisdom of the time and all of them proved correct.

These people were labeled heretics. Their ideas were aired amidst great controversy. Huxley once observed that, "All great truths begin as heresy." Humankind falls into a routine way of viewing the world and then, breaking the continuity, someone observes that the current orthodoxy is at variance with reality. A great debate ensues. New ideas are upsetting. Attempts are made to shout down new opinion. If the idea is grounded in reality, the heretical idea eventually prevails and becomes accepted wisdom. One generation's heresy is frequently the next generation's orthodoxy, which thus sets the stage for the next new heresy. New ideas replace old ideas, but often only after a struggle. This is as it should be. The poet of old observed: "New occasions teach new duties. Time makes ancient good uncouth (Lowell, 1844)."

The great earth-shaking controversies of our history, between science and religion, between church and state, between Christianity and mode culture and, recently, within science itself, all have been characterized a heretic or heretics who challenge the straightjacket of orthodoxy.

New ideas come hard in public policy. Public policy is reactive, and new problems are addressed as long as possible with old solutions. It has a hard time adjusting itself to new ideas. As Barbara Tuchman observed:

Policy is formed by preconceptions and by long implanted biases. When information is relayed to policy makers, they respond in terms of what is already inside their heads and consequently make policy less to fit the facts than to fit the baggage that has accumulated since childhood (1981, p.289).

In the same spirit John Stuart Mill wrote:

When society requires to be rebuilt, there is no use in attempting to rebuild on the old plan. . . no great improvements in the lot of mankind are possible, until a great change takes place in the fundamental constitution of their modes of thought (cited in Commager, 1982, p. 13).



Who are the modern prophets whose heresies will turn into tomorrow's truths? We know they are there, but we differ strenuously on who they are. Some would say Mother Theresa and others Paul Ehrlich. Every person would have their own list. "We see the world not as it is, but as we are" goes an old aphorism. We choose our prophets because they lead where we already think we are going. Like beauty, contemporary prophets are mainly in the eye of the beholder. It is only the future that vindicates our choices. Current assessment of new ideas is so notoriously flawed that we all tell each other that "prophets are without honor in their own country.

I have been convinced for over twenty years that Garrett Hardin is one of the prophets of our time. He has had the courage, intellect, and audacity to take on many of the orthodox assumptions of our age. We will look back from the future and recognize the growing importance of his message.



Time and geometry are on Hardin's side. I suggest there is massive and mounting evidence that we live on the upper slopes of some awesome logarithmic curves. The "new way of seeing and asserting the coherence of the world" in our time is to show that infinite growth cannot take place in a finite world. I choose not to repeat all the depressing statistics. Let me instead use a metaphor. John McPhee has written:

Compare the six days of Genesis as a figure of speech for what has in fact been four billion years geologic time. On this scale, a day equals something like 666 million years and thus:

All day Monday until Tuesday noon, creation was busy getting the earth going. Life began Tuesday noon, and the beautiful organic wholeness of it developed over the next four days. At 4:00pm Saturday, the big reptiles came. Five hours later, when the redwoods appeared, there were no more big reptiles. At three minutes before midnight man appeared and one-fourth of a second before midnight Christ arrived. At one-fortieth of a second before midnight, the Industrial Revolution began.

We are surrounded by people who think that what we have been doing for one-fortieth of a second can go on indefinitely. They are considered normal, but they are stark raving mad (McPhee, 1971, p. 79).

I believe when the history of these times is written it will show our prophets were those confronting the finiteness of our world. Each year our population grows, the deserts creep, pollution seeps and forests shrink, the globe warms, our topsoil erodes; habitats degrade and more and more species disappear. We are in the hinge of history, where ethnocentrically we thought the earth belonged to us, but ecologically we are finding out, to our great astonishment, that we belong to the earth. We are finding that human genius can push the limits of nature but that, ultimately, man cannot conquer nature but is subject to its timeless, inexorable laws.

Despite the massive and growing evidence that we are causing unprecedented harm to our ecosystem, a vast number of people choose to ignore it. No one today can "prove" global warming will inevitably act in a harmful way, and there will always be an optimist somewhere that will relate that the event will ultimately be good for humankind. There are ways simple Simons telling us against all evidence that a negative is actually a positive. It is this type of conflict that too often paralyzes public policy. We cannot know for sure so we do nothing. Ken Boulding (1984) has observed that the essential human dilemma is that all our experience is in the past and yet all our decisions relate to the future. That makes dramatic change hard to accomplish. In absence of proof of the negative, are forever hopeful:

Our images of the future themselves are affected by our evaluations of them. We tend to put too high a probability on futures that we like and too low a probability on those that we dislike (Boulding, 1984).



I know and am sobered by the fact that there has been a myriad Cassandras predicting doom that has not taken place. We know from thoughtful study of history that most utopians and most doomsayers have been wrong. Will and Ariel Durant (1968), after a lifetime of studying history, observed that 99 out of every 100 new ideas that come at a society are bad ideas. It has been very stabilizing to societies and nations to give heavy burden of proof to those arguing for dramatic change. History shows, as a group, they are usually wrong. Most prophets, alas, have been false prophets.



That said, I suggest the next major revolution in human thought will be where humankind confronts the finite. It will be the revolution in science, public policy and human consciousness. It will assert that infinite growth cannot take place in a finite world: that our atavistic thoughts; population and the way our economy is currently structured will be found obsolete and dangerous to the survival of humans on earth. It will bring about a new wave of seeing, and asserting the coherence of the world.

One anthropologist commenting on the worldwide crisis that humanity confronts said:

The extreme novelty of humans as the dominant force on this planet is as surprising as is our current rate of destruction of our own habitat and that of the earth's other life forms. This disregard is all the more striking since, in geological terms, our species has only recently departed from its 'place in nature.' The full implications of our derivation by the random processes of biological evolution in a mere 5 million to 7 million years from an animal much like a chimpanzee have yet to be incorporated in any manner into the fundamental beliefs or institutions of our own, or in fact, any society. In its very success, our species has raised grave problems that demand new kinds of solutions. Will we, by better understanding the processes that made us what we are, grow in capacity to solve the frightening problems of the future arising from our very selves? (Potter, 1989).



This revolution in thought will be more contentious than any that has gone before. There is in the western world a deep-seated cultural belief in abundance, and that a world of plenty is the natural state of affairs. The developed world enjoys its lifestyles and the underdeveloped world seeks to emulate these lifestyles. But increasingly we are finding a new upsetting reality which is at variance with our cultural assumptions.

We are increasingly finding that the oceans cannot endlessly absorb pollution, nor the atmosphere the gases of our industries. We are finding that resources are not unlimited; topsoil is too often ephemeral. We are schizophrenic about our technologies-we marvel at them but we realize that they are not always benign and often come close to being a Faustian bargain. We are finding that economic growth increasingly has byproducts which may cause more harm than the good incorporated by the product.



These concerns will be a new chapter in "seeing and asserting the coherence of the world." Where past genius was recognized for pushing back these limits future genius will be recognized on how to adapt to the vary rapidly approaching limits inherent in living in a limited ecosphere. More accurately, we must both push back these limits and learn to live within the clear overall limits.

When I was 19 a wise person told me "maturity is a recognition of one's limitations." It was hard for me to accept - I had a typical 19-year old desire to read every book, travel to every country, hold every job, live every experience. But, truth won out and maturity was a recognition of my limitations.

So also, I suggest, with the world. We know that no trees grow to the sky; that no species of animal can grow without restraint; and that the harbingers of ecological destruction warn daily of a new set of limits.



AI Bartlett writes:

If an enormous source of low-cost energy is discovered, it is easy to predict what the immediate consequence would be. Our political and economic leaders would collectively breathe a great sigh of relief and would then discard all notions of energy limits. They would rejoice over the advent of a period of uninhibited growth in global rates of energy consumption.

In order to estimate the consequences of likely rates of growth of global energy consumption, we must remember that essentially all of the energy released by human activity winds up ultimately as heat in the environment. First we need some data. The solar power incident on the earth can be calculated by multiplying the solar constant (1.35 x 103 W/m2) by the projected area of the Earth (pRe2). This gives 1.7 x 1017 watts, of which 34% is reflected back into space, leaving 1.1 x 1017 watts of solar power entering the earth's atmosphere. Romer shows that the rate of energy use by humans is 8 x 1012 watts. A simple quotient shows that human activities put into the Earth's atmosphere about 10-4 of the power the sun puts into the Earth's atmosphere. The simple arithmetic of growth shows that one would gain a factor 104 in 14 doubling times. At a growth rate of 3% per year the doubling time is 23 years and 14 doubling times would take only about 300 years.

The arithmetic would suggest that at this modest growth rate, in 300 years human activities would put about as much thermal power into the Earth's atmosphere as the sun puts in! The absurdity of this situation is obvious. Independent of the greenhouse effect, global warming from this direct heating would likely render the Earth uninhabitable long before the passage of 14 doubling times (Bartlett, 1989, p. 10).



Others in this collection will cover in detail the accomplishments of Garrett Hardin. Suffice for my purposes, Garrett Hardin has been one of the main voices of sanity directing our attention to the new realities in which we live. He has had a profound impact on my thinking and I am honored by his friendship. Time will be kind to Garrett Hardin. The future will look back on him as a prophet. His science and his metaphors help us in so many indispensable ways to understand these new realities within which we must live.

The Navajo have an old saying, "The storytellers rule the world." For good reason. It is not enough to see and understand the new realities; one must also articulate them in understandable ways.

Gleick, in his book Chaos, states, "The world awaits the right metaphor" (1987, p. 22). He points out that, no matter how smart we are, we often cannot see something without the correct metaphor. It is thus for his science, his humanity, his heretical ideas, and his ability to show us truth through metaphor that we honor Garrett Hardin.
