Ancient Greeks devised a way to fight disinformation
Sophists used rhetoric and debate to arrive at practical truths.
- Sophists were more interested in arriving at practical truths through rhetoric than an absolute Truth (Sophia).
- Their techniques were heavily criticized by Aristotle, Plato, and Socrates.
- Asha Rangappa and Jennifer Mercieca write that Sophist techniques are particularly useful for recognizing and fighting disinformation.
Octavian had a bone to pick with Mark Antony. The latter claimed the Eastern Roman Empire as he moved in with his lover, Cleopatra. Octavian wasn't having it. He read Antony's official will and testament on the Senate floor in Rome. The document described how Antony was planning on leaving everything to his cunning Egyptian mistress and their children, an idea poking at the many fears and biases Romans held of powerful women. Being a foreigner didn't help Cleopatra. Antony was made out to be a traitor.
The problem? The document was possibly fake.
Whether or not it was actually fake will likely never be known. Octavian's propaganda mission is certainly true, however. He even sketched anti-Antony slogans into coins to denounce his rival. Only the fate of the Roman Empire hinged on their battle.
Disinformation is nothing new. In 1835, the New York Sun published a half-dozen articles about the discovery of life on the moon. The radio broadcast of H.G. Wells's "The War of the Worlds" will not be forgotten anytime soon. Nazi propaganda was so effective that a small percentage of people today believe the Holocaust never happened. People even believe vaccines cause autism.
A convergence of forces produced the dizzying array of propaganda and disinformation in our world today: political manipulation; willful ignorance; social media; anti-intellectualism; scientific ignorance; YouTube. The question is not whether or not disinformation will always exist—it will—the question is how to fight it. For that, we should consider Sophism.
That's the suggestion of Yale University lecturer and CNN analyst Asha Rangappa and American political rhetoric historian Jennifer Mercieca. While they note Plato's skepticism of Sophistry, they believe "clever rhetorical tricks" used by Sophists were necessary for a democracy to function.
The Sophists (A History of Western Thought 8)
Initially, Sophists secured wealthy clients. In exchange for payment, they taught education and rhetoric, as well as music and other arts. Philosophers such as Socrates, Plato, Aristotle, and Xenophon were not fans; they believed Sophistry to be a lowly endeavor designed to sound deep. Socrates sang the praises of Truth (Sophia) alone; his student, Plato, thought Sophist rhetoric manipulated audiences. Sophistry could never lead to Sophia.
Mercieca and Rangappa believe Plato's dialectic was not sufficient to resolve political decisions, however. Socrates's insistence on Truth is debatable, as decades of neuroscience research on memory and perception now tell us. Arriving at one Truth on a planet of nearly eight billion people is impossible; we aren't designed to handle such volumes of data. Even 2,500 years ago, the Sophists strove for Phronesis, or practical truth. They knew that nuance matters.
"Sophists taught the skill necessary for the practice of democracy—how to reach consensus about the truth. They taught people how to create arguments, to persuade audiences to believe their side, and to solve thorny political problems."
Mercieca, a professor, and Rangappa, a lawyer, argue that their professions are more like sophistry than philosophy. Whereas sophistry is usually portrayed as disingenuous, it accurately reflects the shared reality we experience in society.
We shouldn't get caught up in the current usage of sophistry. Words change meaning over time: the Hindu svastik, "auspicious," was co-opted by the Nazis; mythology, with an etymological root meaning "legend" or "story," became synonymous with myth, a falsity. Mythologies are the foundations of cultures, not fabrications.
Employed correctly, sophistry presents an argument that builds into a practical truth, not the Ultimate Truth. In this sense, Sophists and Buddhists share common ground in their love of debates. Monks have a long tradition of critical inquiry often accentuated with hand claps or loud syllables. A handclap (or for that matter, a koan) doesn't sound like a path to truth, yet in the right circumstance it reveals profound meaning. Not all learning is logical.
Debates are essential for democracy. Sadly, social media platforms are designed more for unfriending and trolling than introspection and dialogue. Screens are poor replacements for pantomimes. You read text in your voice instead of the writer's, skewing your understanding of their argument. Lack of intimate contact instigates retreat. You believe the fight is over when the bell hasn't even signaled round one.

Disinformation is especially insidious in the digital age. Social media platforms allow for the quick spread of conspiracy theories. A particularly sophomoric form of persuasion is currently practiced by wellness influencers, who claim to be "just asking questions" while sharing anti-vaxx and anti-5G rhetoric. They then pretend to "not take sides." The problem, as Merciera and Rangappa allude to in the following sentiment, is that propaganda disguised as philosophy promotes an mindset made infamous by George Bush the younger: "You're either with us or against us."
"Propaganda and disinformation are persuasion without consent: In fact, by offering new versions of "facts," their authors try to hide that they're persuading us at all. These forms of communication provide a conclusion based on manipulation rather than reason. Propaganda and disinformation create a realm where disbelief is disloyalty, rather than a shared attempt to search for truth."
Propaganda is compliance, they continue, the preferred vehicle for authoritarians. (Likewise, Plato wasn't a big fan of democracy; he didn't think everyone could access Truth.) Bringing it home to today, the authors cite Twitter fact-checking Trump: an old democratic method, yet one sadly ill-equipped to handle Truth when anything that questions the king is taking a "side." This trend of being "all in" for charismatic figures leaves us on shaky ground. It's how cults form.
A healthy democracy, they conclude, should promote curiosity and debate, tactics more aligned with Sophism than the search for an absolute yet ever-elusive Truth.
"Accusations—rather than argument—and compliance—rather than persuasion—are incompatible with a democratic dialogue. The ancient Greeks rejected unquestioned propaganda and disinformation as well outside of democratic norms. So should we."
America isn't healthy. Our modern Octavian does far more damage than print slogans on coins. This administration has helped foment social conditions that reward vitriol over curiosity. Until a mechanism for questioning propaganda is invented—be it technologically or, more likely, rebooting the operating systems nature has endowed us with—constructive debate will always seem like ancient history.

A Mercury-bound spacecraft's noisy flyby of our home planet.
- There is no sound in space, but if there was, this is what it might sound like passing by Earth.
- A spacecraft bound for Mercury recorded data while swinging around our planet, and that data was converted into sound.
- Yes, in space no one can hear you scream, but this is still some chill stuff.
First off, let's be clear what we mean by "hear" here. (Here, here!)
Sound, as we know it, requires air. What our ears capture is actually oscillating waves of fluctuating air pressure. Cilia, fibers in our ears, respond to these fluctuations by firing off corresponding clusters of tones at different pitches to our brains. This is what we perceive as sound.
All of which is to say, sound requires air, and space is notoriously void of that. So, in terms of human-perceivable sound, it's silent out there. Nonetheless, there can be cyclical events in space — such as oscillating values in streams of captured data — that can be mapped to pitches, and thus made audible.

The European Space Agency's BepiColombo spacecraft took off from Kourou, French Guyana on October 20, 2019, on its way to Mercury. To reduce its speed for the proper trajectory to Mercury, BepiColombo executed a "gravity-assist flyby," slinging itself around the Earth before leaving home. Over the course of its 34-minute flyby, its two data recorders captured five data sets that Italy's National Institute for Astrophysics (INAF) enhanced and converted into sound waves.
Into and out of Earth's shadow
In April, BepiColombo began its closest approach to Earth, ranging from 256,393 kilometers (159,315 miles) to 129,488 kilometers (80,460 miles) away. The audio above starts as BepiColombo begins to sneak into the Earth's shadow facing away from the sun.
The data was captured by BepiColombo's Italian Spring Accelerometer (ISA) instrument. Says Carmelo Magnafico of the ISA team, "When the spacecraft enters the shadow and the force of the Sun disappears, we can hear a slight vibration. The solar panels, previously flexed by the Sun, then find a new balance. Upon exiting the shadow, we can hear the effect again."
In addition to making for some cool sounds, the phenomenon allowed the ISA team to confirm just how sensitive their instrument is. "This is an extraordinary situation," says Carmelo. "Since we started the cruise, we have only been in direct sunshine, so we did not have the possibility to check effectively whether our instrument is measuring the variations of the force of the sunlight."
When the craft arrives at Mercury, the ISA will be tasked with studying the planets gravity.
The second clip is derived from data captured by BepiColombo's MPO-MAG magnetometer, AKA MERMAG, as the craft traveled through Earth's magnetosphere, the area surrounding the planet that's determined by the its magnetic field.
BepiColombo eventually entered the hellish mangentosheath, the region battered by cosmic plasma from the sun before the craft passed into the relatively peaceful magentopause that marks the transition between the magnetosphere and Earth's own magnetic field.
MERMAG will map Mercury's magnetosphere, as well as the magnetic state of the planet's interior. As a secondary objective, it will assess the interaction of the solar wind, Mercury's magnetic field, and the planet, analyzing the dynamics of the magnetosphere and its interaction with Mercury.
Recording session over, BepiColombo is now slipping through space silently with its arrival at Mercury planned for 2025.
Water may be far more abundant on the lunar surface than previously thought.
- Scientists have long thought that water exists on the lunar surface, but it wasn't until 2018 that ice was first discovered on the moon.
- A study published Monday used NASA's Stratospheric Observatory for Infrared Astronomy to confirm the presence of molecular water..
- A second study suggests that shadowy regions on the lunar surface may also contain more ice than previously thought.
Credits: NASA/Daniel Rutter<p>Still, it's not as if the moon is dripping wet. The observations suggest that a cubic meter of the lunar surface (in the Clavius crater site, at least) contains water in concentrations of 100 to 412 parts per million. That's roughly equivalent to a 12-ounce bottle of water. In comparison, the same plot of land in the Sahara desert contains about 100 times more water.</p><p>But a second study suggests other parts of the lunar surface also contain water — and potentially lots of it. Also publishing their findings in <a href="https://www.nature.com/articles/s41550-020-1198-9#_blank" target="_blank">Nature Astronomy</a> on Monday, the researchers used the Lunar Reconnaissance Orbiter to study "cold traps" near the moon's polar regions. These areas of the lunar surface are permanently covered in shadows. In fact, about 0.15 percent of the lunar surface is permanently shadowed, and it's here that water could remain frozen for millions of years.</p><p>Some of these permanently shadowed regions are huge, extending more than a kilometer wide. But others span just 1 cm. These smaller "micro cold traps" are much more abundant than previously thought, and they're spread out across more regions of the lunar surface, according to the new research.</p>

But if there is, it would mean that water would be much more accessible to astronauts, considering they wouldn't have to travel into deep, shadowy craters to extract water.</p><p>Greater accessibility to water would not only make it easier for astronauts to get drinking water, but could also enable them to generate rocket fuel and power.</p><p style="margin-left: 20px;">"Water is a valuable resource, for both scientific purposes and for use by our explorers," said Jacob Bleacher, chief exploration scientist in the advanced exploration systems division for NASA's Human Exploration and Operations Mission Directorate, in a statement. "If we can use the resources at the Moon, then we can carry less water and more equipment to help enable new scientific discoveries."</p>
