To Read God’s Mind
Pythagoreans & the Birth of Science
“This is not the way things were supposed to go,” thought Plato. As
he squatted in the fetid belly of a cargo ship, iron chains rubbed his wrists
and ankles raw.
Just a few weeks ago, he had been warmly greeted by leading
citizens of Tarentum and other rich cities of Magna Graecia. Heated
discussions and drinking bouts long into the night, leisurely walks in lush
orchards seemed to cement friendships with cultivated Greeks from the
colonies, whose sons brought back trophies from the Isthmian Games
while their horses triumphed at the Olympiads.
What had derailed those halcyon days? Hadn’t Archytas welcomed
Plato into his home? Archytas, who had been proclaimed strategos seven
times by the citizens of Tarentum even though the city laws forbade any
man from serving as general more than once, from fear of power going to
his head? Wasn’t Archytas one of the most prominent Pythagoreans of the
age, who reportedly solved the puzzle posed by the Oracle of Delphi
{“Double the altar of Apollo – a cube.”), thus saving Delos from the
plague?
But then had come Dion, from the island of Sicily, singing the
praises of Dionysus, the ruler of the city of Syracuse. Dion promised that
Dionysus would heap honors on the philosopher from Athens and would
eagerly listen to his every word. But the young tyrant had a short attention
span, and at a banquet, he called Plato a doddering old fool. Plato retorted

and at first it looked as if matters had been settled amicably. But the seeds
of enmity had found root, and Dionysus conspired with the ambassador
from Sparta. Traveling on the same ship as Plato, once at sea, the Spartan
had Plato cast into chains, to be sold into slavery.
As soon as the Pythagoreans heard of this treachery, they dispatched
a rescue party to buy Plato’s freedom. As a philosopher, Plato was greatly
animated by the notion of Justice, and his sense of justice would surely
dictate that he owed the Pythagoreans not just coins, but deep gratitude.
Yet in Plato’s voluminous works, across dozens of dialogues, we find the
Pythagoreans mentioned just a handful of times. What the…?!
But this seeming ingratitude points to a little-known facet of a
complicated relationship: Plato had obviously been initiated into the
Pythagorean brotherhood, and members who revealed the secret teachings
were ostracized and banished from memory. All Plato could do was invent
myths and bury the secrets in there.
Later generations would point a finger and accuse: “Plato
Pythagorizes…!” Already Aristotle, Plato’s own disciple, lumped Plato
with the Pythagoreans.
The Pythagoreans say that things exist by ‘imitation’ of
numbers, but Plato, by ‘participation,’ but these are the same,
and Plato only changed the name. – Aristotle
Everything is Number. That was the great leap of the Pythagoreans,
that everything could be measured and quantified. That was the birth of
science, where repeated experiments yield predictably measurable results.
Another link to the brotherhood can be found in Plato’s most
Pythagorean text, Timaeus, where the Demiurge creates the cosmos
according to ratio and number. When describing the planetary system,
Plato invokes the celestial music of the Pythagoreans.

note. And the music of the different spheres gave one harmony.
– Plato, Timaeus
The harmony of the Sirens could be found in a Pythagorean akousma,
a koan-like riddle that only those from the inner circle could explain.
Q: What is the Oracle at Delphi?
A: The Tetraktys that gives the Harmony of the Sirens
The Oracle of Delphi is the oracle of Apollo, the Sun god whose
seven-string lyre leads the dance of the celestial Wanderers, the seven
Planets. What is the Harmony of the Sirens? It’s the celestial music the
Planets produce as they revolve in their orbits.
The Tripod of the Oracle of Delphi on a incuse silver stater of Croton, from
the lifetime of Pythagoras.
How does the Tetraktys link these diverse elements together? When
the Pythagoreans had to swear an oath, they would call upon this pyramid
of pebbles, one at the top, two in the next row, three in the third, and four
in the bottom row.

The true beauty of the Tetraktys jumps out when the whole-number
ratios embedded in it reveal the foundations of Western music, an
encyclopedia written with 10 little stones.
Pythagoras portrayed in Raphael's School of Athens, in the Vatican. By his
left foot, a chalkboard shows the Tetraktys.
The two top rows, the singleton and the next row of two pebbles,
give the ratio of 1:2, the musical interval of the Octave, the universal basis
of music. The two middle rows give the ratio of 2:3, the musical interval of
the Fifth, the next most consonant interval of the musical scale. And the
bottom two rows spit out the ratio of 3:4, the musical interval of the
Fourth, completing the canon and providing all that’s necessary to develop
a mathematical theory of music.
Pagina 5
Vedi nel PDF(si apre in una nuova finestra)If you add the interval of the Fourth to the interval of the Fifth, you
get a perfect Octave, the Tetraktys itself. If you subtract the Fourth from
the Fifth, you get a whole note, the basic unit of the musical scale.
According to the myth, Pythagoras discovered these musical intervals
when he walked by the ringing shop of a smith, whose pounding hammers
beat out different tones on metal bars of varying length.
Pythagoras moved on to string theory, building a monochord that
showed that filaments of differing lengths gave intervals of
mathematically predictable notes, with the pitch measurably related to the
length of the string. In his investigations, Pythagoras came upon an
astonishing fact that still bears his name.
No, it’s not the Pythagorean Theorem, which every schoolchild
hears described these days, but with little elucidation about Pythagoras.
Rarely is it mentioned that Plato proclaimed his allegiance to the
Pythagoreans with the motto engraved at the entrance to his Academy.
“Let no one ignorant of Geometry enter here.”
Yes, the Pythagoreans and Plato’s Academy both demanded a basic
grasp of logic, which was best provided by geometry and mathematics.
Numbers were held in such high regard that they sometimes acquired
almost mystical properties.
“Seven is the key to the universe,” wrote Cicero in the Dream of
Scipio, and he dedicated his translation of Plato’s Timaeus to his
Pythagorean mentor, Nigidius Figulus. Divide the number 1 by the
numerals from 2 to 9, if you wish to divine Cicero’s secret — even Isaac
Newton wouldn’t let go of this esoteric viewpoint.

But it was music and astronomy that were reserved for the highest
echelons of investigation. In astronomy, the seven Wanderers mirrored the
seven notes of the musical Octave, giving the celestial harmony of the
Sirens and suggesting that these widely different branches of learning
were in fact sister sciences.
In music, Pythagoras noted that a cycle of seven octaves matches a
cycle of twelve fifths almost exactly. Almost, but not exactly… The small
difference is called the Comma of Pythagoras, a seal that proves the
presence of the Pythagoreans at the birth of modern science.
The cycling of fifths through octaves produces each and every
halftone of the musical scale, the 12 halftones marked out by the 12 fifths
that revolve through seven octaves. In his book on music theory, Michael
Pilhofer (MM), writes:
Pagina 7
Vedi nel PDF(si apre in una nuova finestra)“The creation and use of the Circle of Fifths is the very
foundation of modern Western music theory…”
Ahhh… Not just the foundation of modern music theory, but music
theory going all the way back to Pythagoras, who stands at the beginning
of the long corridor of time, holding a torch to illumine this dark path.
So important was the cycling of fifths through octaves to the
Pythagoreans that they encoded it into something that people use every
day, yet whose origins remain shrouded in oblivion. Each day, as you
wake up, bring to mind the days of the Week that reflect the musical Circle
of Fifths that cycles through the Octave, the seven days that are named
after the seven Planets.
Moon day (Monday) is the first step up the planetary ladder, as told
by Plato, Vitruvius, Martianus Capella, etc. From there, an interval of a
fifth (skipping three Planets) lands us at Mars, the French Mardi. Another
fifth circling around brings us to Mercredi, the day of Mercury. A further
leap gives us Jeudi, or Jove/Jupiter day, and then we arrive at Vendredi,
the day of Venus. One more hop brings us to Saturn (Saturday), and finally
we rest on Sunday. The next day, we start the week all over again, pushing
the boulder up the hill, just like Sisyphus.
The Pythagorean Music of the Spheres was the grand unifying
theory of the ancient world, and Pythagorean thought would inspire those
who opened the floodgates of modern science thousands of years later.
In Standing On The Shoulders of Giants, physicist and mathematician
Stephen Hawking compiled the scientific works that most impacted
Western scientific thinking. The authors he chose: Copernicus, Galileo,
Kepler, Newton, and Einstein.
Who inspired the revolutionary vision of the heliocentric planetary
system? According to Copernicus, it was Hicetas and Ecphantus of
Syracuse, Pythagorean scholars from Sicily.

Vedi nel PDF(si apre in una nuova finestra)Johannes Kepler would be bounced by fortune from posts as a
simple mathematics professor to highly regarded astronomical scientist.
Tycho Brahe hired him as his lieutenant, to aid in the meticulous
observations of the movements of the planets. When Brahe died, Kepler
got his hands on jealously guarded data that had tracked the motion of
Mars for decades, providing concrete numerical evidence for Kepler’s
Third Law of Planetary Motion.
Where did Kepler look for inspiration for his theories of planetary
motion? First he tried the geometric model of the Platonic solids, but that
did not prove entirely tractable. Digging further back to the Pythagoreans,
Kepler found the Harmony of the Sirens that would yield his masterpiece,
Harmonice Mundi, where Kepler still describes the orbits of the Planets in
musical terms.
Kepler's Harmony of the Planets in Harmonice Mundi
Hoping for assistance from the spirit of Pythagoras, Kepler mused
that perhaps “the soul of Pythagoras has migrated into me.” Through the
prism of Pythagorean Number, Kepler laid the foundations of the Space
Age, and his Laws of Planetary Motion are still used today to calculate the
trajectory of rockets and interplanetary satellites.
Isaac Newton would build on Kepler’s work to march us into the
modern age, but even he retained a fondness for the symmetry inherent in
Pythagorean thought. With a glass prism, he broke up a ray of white light
into its components: red, orange, yellow, green, blue, and violet. But these
are only six colors. For order to be maintained, Newton had to insert a
Pagina 9
Vedi nel PDF(si apre in una nuova finestra)seventh color. That’s how we got indigo, a color that does not exist
independently in the spectrum, but which was necessary, in Newton’s
mind, to maintain the Pythagorean symmetries: Seven notes in the octave,
seven Wanderers in the sky, seven colors in a ray of light, Cicero’s cosmic
seven that revealed the thoughts of God.
As mankind continues to explore interplanetary space, we keep
stumbling upon harmonic intervals and geometric patterns. Neptune and
Pluto exhibit a 2:3 orbital resonance, while the Lagrange points between
celestial bodies adhere to precise geometric alignments.
The Pythagoreans would be delighted.
