Derek Ridgley, Nederland. Physicist Gerald Holton coined the term Ionian Enchantment to describe a belief that the world is orderly and can be explained by a small number of natural laws. The roots of this idea reach back to the Greek philosopher Thales of Miletus, who lived in Ionia during the 6th century B.C. Thales is often seen as a cautionary tale, thanks to his overly ambitious hypothesis that all matter consists of water, but two centuries later Aristotle still described him as the founder of the physical sciences. The enduring significance of his metaphysical speculations was his conviction that nature was endowed with a fundamental unity. The Ionian Enchantment, growing steadily more sophisticated over time, has dominated scientific thought ever since.

For centuries the Holy Grail of physics has been to describe all the forces of nature within a single unified theory. Albert Einstein, though ultimately frustrated in his effort to reconcile Newtonian mechanics with quantum uncertainty, was Ionian to the core. As it happens, His Holiness the Dalai Lama is also an Ionian at heart. In his book The Universe in a Single Atom, His Holiness makes a compelling case that rather than competing explanations for the universe, empirical science and philosophical spirituality are addressing related phenomena and will inevitably converge. 

One potential example comes from physicist Roger Penrose and M.D. Stuart Hameroff, who have theorized that cytoskeletal microtubules, organelles inside the cells of brain neurons, function as molecular quantum computers. Put simply, they posit that these structures interact with the fabric of space-time at a quantum level, the byproduct of which is consciousness. Though unproven, a neurological anchor for human consciousness that communicates directly with the universe would certainly bridge the chasm between physics and spirituality.

The eminent biologist Edward O. Wilson has his own twist to the Ionian Enchantment, proposing that knowledge generated by specialists in physics, biology, chemistry and other disciplines is intrinsically unified. A body of natural laws, Wilson argues, interlocks that knowledge in what he calls Consilience. Examples are abundant, particularly in the study of self-organizing systems, aka emergent adaptation. 

Wilson’s early career was spent researching ants. Ants fascinate biologists because they demonstrate adaptive intelligence even without a commanding intelligence. Colonies forage, build nests and respond to environmental changes without direct instructions from the queen. Instead they crowdsource decisions from the input of relatively simple agents, the worker ants.

To unravel emergent systems, biologists eventually collaborated with mathematicians who saw ant behavior as an echo of the information theory work of Alan Turing, the father of computer science. That cross-pollination of biology and math has occurred repeatedly, most famously in the founding of Google. 

In 1996 Stanford PhD students Larry Page and Sergey Brin created an algorithm for scientific research papers that ranked the importance of each paper based on the citations received in other research. Next they famously applied this inference technique to backlink data for World Wide Web pages, using algorithms that mimic the way scent trail aggregation guides the behavior of ant colonies. Research on distributed agent systems also informs algorithms that today are incorporated in the “deep learning” neural networks used in commercial AI.

The amoebalike slime mold is another emergent system decoded by a synthesis of scientific disciplines. A close relative of fungi, slime mold are primitive organisms. Despite having no centralized brain, they have demonstrated maze-solving capabilities in lab studies. In the wild, the slime mold spends much of its life as thousands of discrete single-celled units. Under certain climate conditions, those myriad cells coalesce into a single large, gelatinous organism that slowly prowls the forest floor consuming rotting leaves and wood.

Biologists had long understood that the slime cells emitted a substance called acrasin (also known as cyclic AMP). In 1962, biologist B.M. Schafer demonstrated how waves of cyclic AMP secretions could trigger the aggregation process. He concluded that the AMP cascade must be launched by commands from “pacemaker” cells, ordering the others to assemble. But after 20 years of searching, mycologists were unable to find Schafer’s pacemakers. It took the efforts of physicist Evelyn Fox Kellar and mathematician Lee Segal to solve the riddle. Using math that is normally applied to fluid dynamics they demonstrated that individual slime cells, simply releasing AMP in response to local climate changes, could lead to cells following trails left by other cells. This positive feedback loop triggered the clustering behavior that led the slime mold community to aggregate - without any pacemaker calling the shots.

Often it is difficult to “see the forest for the trees.” Among the tsunami of data we gather about our natural world, examples of Consilience are multiplying. Insects and fungi exhibit self-organizational behaviors that mirror the way fluids move, and which anticipate how Internet search engines find information and the way computers teach themselves to recognize patterns. Biology is merging with chemistry and genetics, which are merging in turn with particle physics and mathematics. The promise of the Ionian Enchantment has never burned brighter. Perhaps the Dalai Lama is right after all in asserting that natural science will inevitably converge upon the irreducible truths found in philosophical spirituality.
