The Power of Thought and the Wonder of Nature

Fresno Bee, April 14, 2024

Far from being fearful, the total eclipse inspires wonder, awe and humility

Last week’s solar eclipse shows us how far we have come in our understanding of nature. We now predict eclipses with precision. The calculations of modern astronomy are obviously superior to primitive superstitions that saw eclipses as omens or as the work of gods and demons.

Western philosophy and science are often traced back to the ancient sage Thales of Miletus, who was famous for predicting an eclipse in May 585 BCE. Some say that Thales was the first ancient star-gazer to correctly predict an eclipse. I doubt that. Ancient cultures carefully observed the sky. Thales likely learned astronomy from the Egyptians. Nonetheless, the ability to predict an eclipse was a sign of wisdom.

As the saying goes, “knowledge is power.” Understanding the causal story behind an event provides us with power. Broad understanding of nature creates a kind of mastery. And knowledge alleviates the anxiety of the unknown and uncanny. Knowing why things happen makes them less spooky. It also allows us to take action to avoid harm, generate benefits and gain control. This is the promise of science, mathematics and natural philosophy.

Despite this promise, it took centuries of cultural struggle for the scientific method to prevail. Religious institutions often resisted that change. The most famous case is the Inquisition of Galileo, which began on April 12, 1633.

Galileo defended the idea that the Earth moved around the sun — the heliocentric model of the universe. He based this on the astronomical calculations of Copernicus and his own observations of the heavens through telescopic lenses. But the religious dogma of the day held that the Earth was the center of the universe and that the other celestial bodies moved around our fixed world.

Galileo challenged that idea. But he was not an atheist. He thought that science helped elucidate the divine order of things. His scientific observations were meant to read the book of nature as a supplement to the holy book of Christianity. But Galileo’s heliocentric model called some of the Bible into question. Galileo lost his struggle with the church. He was forced to recant.

It took centuries of further development to come up with the present model of the cosmos. Today we know much more about our place in the universe. We know that our sun is one star among the billions in the Milky Way and that our galaxy is one among billions of galaxies. We also know that there are other planets orbiting distant stars. It is likely that eclipses happen on other planets as well, since there are other moons orbiting other planets, even in our own solar system.

And yet, there is something special about an eclipse as it occurs on Earth, since there is a kind of symmetry between the apparent size of the moon and the sun. If the moon were smaller or were farther away, there would be no such thing as a total eclipse. Nor would there be a total eclipse if the sun were larger.

Scientists predict that at some point the sun will grow larger and the moon will move farther away from the Earth. This means that at some point in the distant future, there will no longer be total eclipses on Earth.

That fact should inspire wonder, awe and humility. We are fortunate to live here now. On this planet at this time, our satellite and sun work together in a special way. Even if there are other planets out there with other moons, and other forms of intelligent life, total eclipses may be rare.

It is important to dwell in this kind of wonder and awe. Scientific knowledge shows us how privileged we are to be here, now. It reminds us how fragile our existence is. From this we might develop a kind of humility and insight.

Thales seemed to possess that kind of wisdom. He celebrated the unique beauty of the universe as a divine gift. He said that the mind is swift and powerful, since it is able to expand everywhere. And he claimed that time is the source of wisdom, since it brings everything to light. There are moments of darkness. But if we are patient, persistent and wise, the light may dawn.

On the Importance of Looking Up

The new Netflix film “Don’t Look Up” has a lot of people talking.  It is a black comedy, starring Leonardo DiCaprio, Meryl Streep, and Jennifer Lawrence. It’s about corporate greed, bureaucratic incompetence, and the apocalypse.  Its bleak conclusion gets you thinking about the dangers of power, narcissism, and willful ignorance. 

The movie’s fans see it as a cautionary allegory about climate change, science denial, and clueless amateurs running the government.  Some worry that its gloomy ending may encourage despair.  Others hope it will be a call to action. 

Reviews of the film reflect our polarization.  Conservatives claim it is another example of Hollywood preaching a liberal gospel.  One critic in the National Review suggested it is the worst film of 2021.  He lambasted is as a “better-than-you comedy” that “reveals the nastiness of liberals.”  Another critic in the Washington Examiner said it was a “lazy anti-Trump comedy.” 

More subtle criticism came from New York Magazine, where a sympathetic commentator accused the film of oversimplifying the climate crisis.  He said liberals “need to stop telling themselves self-flattering fairy tales.”

I suppose the point is that we are all in this together.  Narcissism and stupidity cross party lines.  Hollywood is part of the problem.  The film seems to recognize this.  It shows how the cult of celebrity corrupts everyone, even the neurotic scientist played by DiCaprio. 

At any rate, this is an allegory, not a documentary.  Allegories simplify reality. They tell memorable stories that get people talking.  In this regard, the film succeeds.  It provokes conversations about life, death, politics, and American culture. 

This conversation should extend to the very idea of “looking up.”  The film’s title calls to mind Plato’s famous “allegory of the cave.”  In Plato story, we are prisoners chained in a cave.  We are not permitted to turn around and see reality.  Even when we are set free, most of us refuse to turn around. Plato suggests the masses would go so far as to kill truth-tellers and educators, who like Socrates are trying to get us to look up.

Plato’s allegory is about willful ignorance. Plato warns that most people don’t want to know the truth.  We deliberately choose not to look up.  We are happy with our illusions.  We don’t want to confront reality.  We keep our heads down, preferring slavery over enlightenment.

In the film, this idea becomes the slogan of the political party led by Streep’s character, President Orleans.  The party encourages people not to look up at the comet hurtling toward earth.  This is a parody of our culture’s struggle with science denial, “fake news,” and “alternative facts.”  It also implies authoritarianism.  “Don’t look up” also means “mind your own business” and don’t criticize the elites.

The philosophical solution to all of this is the pursuit of wisdom.  We ought to look up.  It won’t be easy or comfortable.  We may discover things that confuse us or make us unhappy.  But it is better to live in the light than in the darkness.

One of the questions raised by the film is whether you would want to know how and when you are going to die.  The scientists in the film know the exact time of the apocalypse.  And there is a supercomputer using big data to predict how people will die. 

What would you do with this knowledge?  Would knowledge of your death cause despair?  Would you prefer to remain in ignorance about your death?

A modest hopeful appears toward the end of the film when DiCaprio’s character responds to knowledge of his death by changing his life.  He refutes the computer’s prediction about his death, thereby reclaiming some modest dignity.

This is the kind of dignity that knowledge provides.  When we look up and confront reality, we can take charge of how we live and how we die.  To live in ignorance is to live as a prisoner.  The truth sets us free. 

Knowing the truth won’t change the indifferent reality of the cosmos.  Knowing the truth won’t stop a comet or cure you of Covid.  But knowledge allows us to live responsibly and, if necessary, to die with dignity.  It is tempting in a crisis to bury our heads in the sand.  But wisdom is only available to those who look up.

Amateurs, Morons, and Professionals

There’s an ironic critique of amateurs in The Big Lebowski. Walter (played by John Goodman) keeps complaining about “f***ing amateurs.”  But Walter is an amateur.   He is a caricature of the great American “do-it-yourself” ethos. 

He claims that other people don’t know what they are doing.  But neither does he.  And so Walter keeps f***ing things up.

Some things ought to be left to the professionals.  A professional has specialized training, lots of experience, and a certain talent or skill.  But Americans distrust professionals.  We think that since we are all created equal, we should be able to do-it-ourselves.

Our suspicion of professionalism has some connection with Trumpism, the anti-vax movement, and the American distrust of science.  Professionals are elites.  But we don’t like elites.  We’d rather diagnose our own diseases and interpret the data for ourselves.  We think we are smarter than the doctors, the scientists, and the “mainstream media.”

As we’ve seen, this can lead to disaster.

The conflict between professionalism and amateurism is an ancient one.  Plato criticized democracy as a rule of amateurs.  According to Plato, this is a terrible idea.  Plato’s ideal republic is a nation run by professionals.  He describes a rigorous training method for selecting the rulers.  And he suggests that tyrants have not successfully completed the program.

Tyrants are the worst of the amateurs.  The etymology of the word “amateur” gives us a clue.  The root of the word is “love” (ama-).  Tyrants love power.  But they don’t want to develop the skill, virtue, and expertise necessary to rule.  They grab power without training themselves in wielding it wisely. 

This is not to suggest that all amateurs are tyrants.  There is something admirable about a dedicated amateur.  Amateurs do things because they love them.  They are not in it for the money or the fame.  But a virtuous amateur understands that some things ought to be left to the professionals. 

Things have changed quite a bit in recent decades when it comes to the difference between amateurs and professionals.  The Olympics, for example, used to ban professional athletes.  And while amateur athletes are inspiring, the pros are better.

In some fields, the professionals have been kicked to the curb.  In other fields, increased specialization makes it impossible for amateurs to survive.  Often this is about money: who makes it, who controls it, and where it flows.

At one time, Youtube was a place for amateurs to share videos.  But Youtube went commercial and the professionals staged a comeback, elbowing out the amateurs in pursuit of advertising revenue. 

Similar struggles have played out in other corners of the economy.  Ride-sharing apps like Uber compete with professional cab drivers.  Airbnb circumvents the professionals at Hyatt and Hilton.  Amazon allows self-published authors to reach a wide audience.  And so on.

Each of these stories is complicated.  In some cases, the rise of the amateurs has allowed for an outburst of creative entrepreneurship.  In other cases, you end up with crappy self-published books and weird cars driving you around town.

There is also lots of confusion about what’s true, what’s real, and what’s beneficial.  The Covid-19 debacle shows us what’s at stake.  Rather than trust the scientists, the amateurs are playing doctor. 

Early in the pandemic, non-experts claimed that Covid-19 was no worse than an ordinary cold or flu.  Then the amateurs doubted professional advice about masks and social distancing.  And now the non-professionals are skeptical of vaccines.  Meanwhile, the pandemic rages on.

Plato was right that in an ideal world we’d put the professionals in charge.  But in a democratic country that values individual liberty, the amateurs will resist.  The solution is better education.  But that’s a long-term and ongoing solution. In the meantime, we’re left with a mess. 

At one point in The Big Lebowski, the Dude (Jeff Bridges) says to Walter: “Walter, I love you, but sooner or later, you’re going to have to face the fact you’re a goddamn moron.” This is us. Let’s face the fact that we are a bunch of amateurs and morons, mucking things up. What’s not to love?

Waning Religion and Our Epicurean Moment

Epicurus

Religious membership in the U.S. has dropped below 50% for the first time, according to a recent Gallup Poll.  Some Americans continue to believe in the supernatural.  A 2020 survey indicates that half of Americans believe in ghost and demons.  But it is remarkable that today fewer than half of Americans belong to an organized religion. 

This new data confirms other surveys indicating secularization.  The Pew Center has documented the rapid growth of “the nones” (those who do not claim to belong to a specific religion) and the decline in church attendance. 

Some pundits worry this indicates a cultural malfunction.  Dennis Prager says, “When Judeo-Christian principles are abandoned, evil eventually ensues.”  Shloto Byrnes says that the West is suffering from a “Godless delusion,” arguing that “to be human has meant to be religious throughout history.”  And Shadi Hamid suggests that secularism fuels political extremism. 

These hyperbolic concerns are misguided and misleading.  Many societies have done quite well without Judeo-Christian values.  It is not true that human beings have always been religious in the contemporary sense, or that we need to be.  And rational humanism actually offers an antidote for extremism. 

The Covid-19 crisis provides a great example.  Prayer and miracles will not solve this crisis.  Scientific medicine provides vaccines, prevention protocols, and treatments for infection.  When people get sick these days, they go to the doctor instead of the shaman. 

Scientific naturalism is ubiquitous.  To predict the weather, we consult meteorologists instead of astrologists.  Earthquakes and volcanoes don’t appear to us as the work of mercurial deities who need appeasing.  Reason and humanism provide us with useful advice that improves health and happiness.

And despite what Byrnes says, humanism has a long history.  It made a strong appearance 2,500 years ago in the philosophy of Epicurus.  The Epicurean philosophy aimed to cure the anxiety caused by religious superstition.  Epicurus offered thoroughly naturalistic explanations of earthquakes, lightning, and the like.  The Epicureans taught that happiness was easily obtain by focusing on friendship and virtue in a world emptied of the supernatural. 

The Epicurean philosophy was popular in the ancient world.  But Stoic and Christian authors vilified Epicurean naturalism.  Epicurus’s name was falsely associated with licentiousness and shameless hedonism.  This caricature is unfair to a school that emphasized modesty, frugality, and friendship—and the deliberate avoidance of political extremism.

As a result of persecution, however, few of Epicurus’s original writings exist.  We do know that Epicurus defended an early version of atomism based in a naturalistic view of the world.  His views are remarkably modern. 

Epicurus taught that the cosmos was made up of atoms moving in the void.  He held out the possibility that in the infinite space and time of the universe, there were other worlds that resulted from the same natural processes that produced our world. 

Epicurus said that the soul was merely a combination of certain kinds of atoms.  When the body died, the soul dissipated.  There was no life after death.  If there were gods, they were not concerned about human life.  Religious myths and superstitions caused anxiety by making us worry about the whims of the gods and life after death.  In order to cure that anxiety, a better understanding of nature helps.

Epicureanism also provided an antidote to extremism.  Religious zealots sometimes end up trying to silence the advocates of reasonable naturalism.  They can also fall prey to outrageous conspiracy theories. But rather than engage these zealots in the streets, the Epicureans advised living unobtrusively.  Political tumult results in unhappiness.  The Epicureans tried to avoid that by retreating to private communities, where friendship, reason, and happiness could be cultivated. 

It seems that now is a good time for an Epicurean renewal.  Religion is waning. And while some zealots are succumbing to extremism, most of us are rediscovering the importance of science, reason, and restraint.

The Covid lockdown has also encouraged us to find happiness in simple things.  While extremism and violence has erupted in the streets, we are re-learning the wisdom of living simply and with social distance.  This is an Epicurean moment: a time to rediscover the wisdom of naturalism, a time to turn away from superstition, and a time to cultivate modesty, simplicity, and friendship.

Religion and Education

Are education and religious liberty mutually exclusive?

Fresno Bee, May 5, 2017

College education generally makes us less religious, according to a new study from the Pew Research Center. Educated Christians are more likely to go to church on a weekly basis than uneducated Christians. But college graduates are less likely to say religion is “very important” in their lives.

College graduates are also more likely to be atheists. Fifteen percent of those with advanced degrees do not believe in God, while only 6 percent of noncollege grads are atheists. Meanwhile, 42 percent of those without college education think that religious scriptures should be taken literally, compared with 14 percent of those with college degrees.

Science education make religious fundamentalism difficult to sustain. The Earth is a speck among hundreds of billions of stars. Our species evolved long after the dinosaurs went extinct. The land was once covered by ice powerful enough to carve out Yosemite Valley. None of this is recorded in ancient scriptures, which teach that the gods have a special interest in this planet and in human beings. 

HISTORY AND ANTHROPOLOGY ALSO CHALLENGE RELIGIOUS FUNDAMENTALISM.

Traditional accounts of the soul are also being explained away. Biomedical science locates consciousness in the brain. And evil is explained in neurological or psychological terms instead of as a matter of demonic possession.

History and anthropology also challenge religious fundamentalism. The ancient Chinese or the Aztecs never heard of the Christian scriptures. Nor do Christian scriptures mention these ancient civilizations. This makes simplistic declarations about God difficult to understand. When we say “In God We Trust” in our diverse world, which God are we are talking about: Jehovah, Allah, or Quetzalcoatl?

Even within the Christian tradition there are disputes about God and revelation. Mormons, who comprise about 2 percent of the American population, believe that the Book of Mormon is a holy Christian scripture. Other Christians claim this is false.

Scriptural interpretation has evolved over time. The book of Joshua explains that God held the sun still in the sky in order to allow Joshua’s troops to slaughter their enemies. But after Galileo debunked the geocentric model underlying this story, it has been subject to reinterpretation.

Others have questioned the morality of a God whose miraculous power is used to slaughter an enemy. Evolving moral standards have led many Christians to reinterpret scriptures that contain morally problematic passages about slavery, the subordination of women, homosexuality, polygamy, divorce, and so on.

Religious belief has often been flexible and subject to reformation and reinterpretation. Religions evolve to take in new information and reflect new norms. We make sense of ancient texts in light of modern ideas.

Atheists may view all of this as an argument against religion in general. And indeed, a quarter of Americans have left religion behind – either affirming atheism or simply giving up on organized religion.

But religions are persistent. The diversity and flexibility of religious belief is a key to this persistence. Religions that don’t adapt go the way of the dinosaur. No one worships Zeus or Quetzalcoatl any more. But Christianity thrives because of the variety of Christian denominations. There are over 200 different versions of Christianity in the US. You can pick an interpretation that suits your preferences.

LIBERTY ALSO ALLOWS PEOPLE TO CHANGE RELIGIONS.
INDEED, ABOUT A THIRD OF AMERICANS CHANGE THEIR RELIGIOUS AFFILIATION.

Religious liberty thus helps religion to persist. Liberty allows for innovation and development. Liberty also allows people to change religions. Indeed, about a third of Americans change their religious affiliation.

In the free marketplace of religious ideas, religions sell themselves to people and reflect changing tastes. Catholics no longer say Mass in Latin. Protestants have embraced pop music. And Western faiths have incorporated meditation, yoga and other spiritual practices from Eastern traditions.

In the modern democratic and capitalist world, we value educated and informed choice. We want informed consent in health care, in financial transactions and in elections. We should also value informed choice when it comes to declarations of faith. In a democratic culture, we ought to learn about other faiths and shop around. We also ought to leave each other alone to pursue the religious quest in our own way.

Things may have seemed simpler when a common piety was enforced on the uneducated masses. Freedom and science do undermine traditional religious conformity. But modern democratic people have faith in the power of education and religious liberty to make this a better world.
