In his 2008 book Reinventing the Sacred, complexity theorist Stuart A. Kauffman tells an apocryphal story of the invention of the tractor. Portable engines had been invented for the purpose of powering farm machinery in the early 1800s. The question by mid-century was how to embed an engine directly into the machinery. No reasonably-sized chassis could bear the weight of the engine. Eventually an engineer working on the problem suggested using the sturdy, rigid engine block itself as the chassis. This solution led to the invention of the tractor. This story illustrates Kauffman’s principle of “emergence,” which describes how every new thing—new molecules, species, technologies, economies, cultures—comes into the universe for the first time—not at the very beginning, but as a part of a continuing creative process inherent in the universe. This principle is so compelling to Kauffman that he proposes we call it God. Hence the title of his book, Reinventing the Sacred.
It would never have occurred to me to read this book, but luckily for me, when Fred and Phil Sawyer purchased a sermon at last year’s goods and services auction, Fred assigned it. “Luckily.” As I remember it, Fred handed it to me saying something like, “I got nothing out of it; I’m not a biologist; maybe you can tell us why this matters.” I remember thinking, “I’m not a biologist either!” But I’m always up for a challenge. And reading this book was a challenge. Much of the science is dense and beyond my comprehension. But I know enough to understand the significance Kauffman attaches to the science. And what he says does matter—not because he has found God, but because his science reveals a mysterious, creative dimension at the heart of the universe—one that can inform us in a profound way what it means to be human. Ready?
I think it’s fair to say the average human isn’t typically aware of a mysterious, creative dimension at the heart of the universe. We might catch fleeting glimpses of it in the midst of worship, or in the presence of beautiful art or nature. If we desire a more sustained experience of it we need to work at it. It requires a prayer life, a devotional life, a meditational life. It requires regular practices that connect mind, body and spirit to each other and to the world. But that’s not what the book is about. Kauffman contends we need a new scientific worldview. In fact, the reason we aren’t typically aware of the mysterious, creative dimension at the heart of the universe is because the reigning scientific worldview, reductionism, blocks such awareness.
“Reductionism,” says Kauffman, “is the view that society is to be explained in terms of people, people in terms of organs, organs by cells, cells by biochemistry, biochemistry by chemistry, and chemistry by physics…. It is the view that in the end, all of reality is nothing but whatever is ‘down there’ at the … base of physics….” What’s down there? Atoms and subatomic particles like pions, muons, guons and the Higgs boson. A string theorist would say there are vibrating strings down there.
Presumably, there are laws governing the behavior of these microcosmic entities, just as there are laws governing the behavior of planets and stars. If we can articulate these laws, if we can know what each minute entity will do in any given situation, then theoretically it is possible to know everything that will happen. This is reductionism’s goal. We’ve succumbed to the Galilean spell. Kauffman says “since Galileo rolled balls down incline planes and showed that the distance traveled varied with the square of the time elapsed, we scientists have believed that the universe and all in it are governed by natural laws…. Under this spell we have believed reductionism for over 350 years.” The spell is seductive. If we can find the natural laws governing the physical world, then we can know everything that will happen in physics. Kauffman says knowing a natural law means we can pre-state what is going to happen. If we can pre-state everything that will happen in physics, then we can pre-state everything that will happen in chemistry and on up the chain: biochemistry, cells, organs, people, societies. With such knowledge we can unlock every secret in the universe.
But Kauffman also reminds us of a shadowy truth at the heart of reductionism: “The more we comprehend the universe, the more pointless it seems.” That is, physics only tells us what happens. It only tells us facts. There’s no meaning or purpose embedded in the interaction of subatomic particles. If everything—including consciousness—can be reduced to particles colliding, then at the heart of reality there is no meaning or purpose. There is no agency. Nothing utterly new emerges, and there is certainly no God. It’s all utterly pointless.
Kaffman resists this conclusion. He is convinced we aren’t just particles colliding. We have agency. There is meaning and purpose. These things didn’t exist at the beginning of the universe; they have emerged into the universe over time and they cannot be reduced to physics. Kauffman proposes to break the Galilean spell. He makes this proposal based primarily on his understanding of a concept in the theory of evolution called preadaptation. What is preadaptation? Any biological organism has features that are more or less adapted to its environment and enable it to survive and reproduce. But what happens if the environment changes—becomes colder or warmer, wetter or dryer—and the organism’s survival needs change? The study of evolution reveals that in such situations, some of the organism’s features may take on new functions that have no relationship to their original functions. Scientists call this preadaptation.
This is why Kauffman tells the tractor story. The engine block’s original function is to support the components of the engine. But some engineer imagined the engine block could also be used as the tractor’s chassis. The engine block wasn’t designed to be a chassis, but as needs changed, it emerged as a chassis. It was preadapted to function as a chassis even though it wasn’t designed to function as a chassis. Kauffman also talks about screwdrivers, which were designed to turn screws. “But how many other novel uses can the screwdriver be put to? It can be used to open a can of paint … to scrape putty from a frozen window … to defend yourself against an assailant … as an object of art … as a paperweight … to carve your initials on a fine tabletop, spear a fish, crack a coconut, chop down a tree using a rock to hammer if you are on an isolated island making a hut.” When we use a screwdriver for any purpose other than turning screws, we can say it is preadapted for these other functions.
That’s the principle. Returning to actual biology, Kauffman talks about how the three bones in the fish jaw were preadapted to evolve into the bones of the middle ear in mammals. He talks about how ancient fish lungs evolved by preadaptation into the swim bladder. There are countless examples of preadaptation in nature. It is one of the primary mechanisms by which novelty emerges into the universe. And whenever something new emerges into the universe, it also changes its environment, putting survival pressure on other organisms, thus creating opportunities for emergence to continue in endless cycles. Emergence does not violate the laws of physics, but there is also no physical law that fully governs it either. Kauffman says there can be no such law because “we have not the faintest idea of what all possible [environmental changes] might be … and no way to list all possible … environments with respect to all … features of organisms. How would we even get started on creating such a list? Thus we cannot [pre-state] the … preadaptations that will come to exist in the biosphere.”
Remember the mysterious, creative dimension at the heart of the universe? Here it is. Reductionism can’t explain it because reductionism requires laws. Emergence is a partially lawless phenomenon.
Kauffman calls this mysterious, creative dimension at the heart of the universe God. Throughout the book he is clear he can’t accept the idea of an all-powerful, transcendent, Creator God. But he also can’t accept reductionism’s pointless universe. He believes he has found a third way, a scientifically describable creativity inherent in the universe which, because no natural law governs it completely, is also eternally mysterious. Isn’t God a good name for it? This is how he reinvents the sacred. But there’s no reinvention here. Most theologians would call his theology pantheism, the idea that God is synonymous with the natural world. If the natural world is inherently creative, partially lawless and unknowably mysterious, then God is creative, partially lawless and unknowably mysterious. Pantheism comes in many forms and is quite ancient. I’m a pantheist. Many Unitarian Universalists profess some form of pantheism, even if they don’t use the word.
I’m not blown away by his theologizing, but I’ve loved contemplating what it means to be human in this inherently creative, partially lawless, unknowably mysterious universe. Every time Kauffman illustrates how some biological process, or the human mind, or the biosphere, or the economy or human culture cannot be reduced to physics, cannot be contained within the boundaries of natural law; or how some change in biology, the economy or culture cannot be pre-stated—his science reveals an infinite space all around us and in which virtually anything can happen. He calls it the adjacent possible. Every possible preadaptation, every path to something new exists there, and everything that emerges new into the universe emerges there. This doesn’t mean that every new thing that can happen will happen, but something new will happen. In a sense we are constantly entering a sliver of the adjacent possible.
As an example, he notes “that the early Earth … had only a small diversity of organic molecules, perhaps a hundred or a thousand different compounds. Today there are trillions of different organic compounds spread among the roughly 100 million living species. The biosphere has exploded into its chemically adjacent possible. We will find similar explosions in economics, human history and elsewhere…. The creativity in the universe is tied to the explosions into the adjacent possible.” Every new chemical compound, cell or organism, every new use for a screwdriver, the inner ear, the swim bladder, the automobile, the airplane, the emergence of smell, sight, hearing, taste, touch through evolution—even every new thought—
brings us into the adjacent possible. And every time something new comes into the world, a new adjacent possible comes into existence. Endless creativity.
I invited Molly Vigeant to compose a poem in response to the prompt: “is the human mind like a computer?” She wrote: my mind connects / each neuron / like a cable to a memory / that means something to me, / my cables connect / finding results to your questions, / to my questions / but i do not display the results / you see my mind / does not work like that laptop …. I gave her this prompt when I was reading Kauffman’s chapter on the human mind. He asks whether or not the human mind is like a computer. He and Molly agree. Our minds do not work like laptops. Computers are algorithmic. They use algorithms to make complex calculations. Humans use algorithms—long division is an example—but is the human mind algorithmic like a computer? For an algorithm to work, there must be boundaries. There must be what Kauffman calls a pre-stated problem space. The algorithm finds a solution within the boundaries of the problem space. Once the problem space is pre-stated, there are many solutions that can be found within the space, but not beyond it. There is no adjacent possible for computers. Laws set limits. The human mind, however, knows no such limits. Molly almost begs us, “Please / don’t call me a computer /when I compose rhymes, call it the power / of a human mind.” Kauffman says, “the human mind, like a ghost ship, keeps slipping free of its computational moorings to sail where it will. It does so because it is nonalgorithmic. This freedom is part of the creativity of the universe.”
Yes! The human imagination crosses boundaries into the adjacent possible all the time: in dreams, in creative endeavor, while under pressure, in the throes of passion, in problem-solving, in prayer, in meditation, while doing yoga, dancing, running, day-dreaming, free and easy wandering. I’m mindful of our opening words from Howard Thurman: “The movement of the Spirit of God in the hearts of [people] often … causes them to anticipate a spirit which is yet in the making.” Any time we’re struggling and realize we need to live differently, the adjacent possible beckons. Any time we encounter difficulty, hurt, tragedy and need to adapt to new circumstances, the adjacent possible beckons. Any time we’ve become weighted down by habit or addiction and need to reinvent ourselves, the adjacent possible beckons. But it cannot be pre-stated. There is no way to know ahead of time what the mind will imagine, what answers will emerge. We’ll know once we’ve found our way there.
This is what it means to be human. We live in a partially lawless universe, not knowing what the future may bring. In this sense we are surrounded by mystery, which can be terrifying. But we are also surrounded by infinite pathways, infinite promise. The adjacent possible is always accessible. Knowing this, trusting this, believing this, let us not fear mystery but rather embrace it. Let us live in consort with the creative heart of the universe. Knowing the adjacent possible is there, may we find inspiration to meet the challenges of our lives. Knowing the adjacent possible is there, may we be hopeful people.
Amen and blessed be.

Kauffman says this “is how tractors are made,” but he doesn’t cite any sources. A quick google search informs me that “in 1892, John Froelich invented and built the first gasoline/petrol-powered tractor in Clayton County, Iowa, USA. A Van Duzen single-cylinder gasoline engine was mounted on a Robinson engine chassis, which could be controlled and propelled by Froelich’s gear box.” See: https://en.wikipedia.org/wiki/Tractor.
