Am I Being Dishonest About Fine-Tuning?

In recent discussions with atheists on Twitter, I’ve encountered objections to the term “fine-tuning.” This term refers to the fact that, according to physics and cosmology, the fundamental physical constants and forces of the universe (the strength of gravity, the strength of electromagnetism, the cosmological constant, the number of spatial dimensions, and so forth) all appear to be precisely “tuned” within an extremely narrow range—an incredibly delicate balance that permits the existence of life in the universe. There are dozens of these constants and forces, and if just one of them had a slightly different value—if it were altered by as little as one part in billions or even trillions—life could not exist.

I find that most of the atheists I encounter have never heard of fine-tuning or the anthropic principle. When I explain it to them, they are aghast and refuse to believe what I’m saying. They frequently accuse me of lying or ignorance.

Those who are more astute and well-read will frequently object to the term “fine-tuning” because they think that even using that term is stacking the deck. “‘Fine-tuning’ requires a Fine-Tuner,” wrote one. “The term ‘fine tuning’ is a conclusion disguised as a premise: the argument is truly, technically circular.”

To his thinking, the term “fine-tuning” implies intentional tinkering with the laws of physics by a deity. That’s not how the term is commonly used and understood within the scientific community. “Fine-tuning” is actually a values-neutral, secular, scientific term that describes the nature of the constants and forces of the universe. Physicists, cosmologists, and astronomers actually do observe the universe to be “fine-tuned” without regard to how it got that way. It’s a description of the state of the universe, and does not presuppose how the universe got that way.

Whether or not there was a “Fine-Tuner” (i.e., God), the universe is fine-tuned. It is certainly conceivable that the universe could have come into existence by random-chance processes—with all of its physical constants and forces balanced within that incredibly narrow range, and without the intentional intervention of a “Fine-Tuner.”

Let me say that again for emphasis: Even if there was no intelligent “Fine-Tuner,” the universe is undeniably fine-tuned.

Atheists who wrongly accuse me of trying to bias the discussion with the term “fine-tuning” are themselves guilty of trying to force the discussion toward their conclusion by taking a perfectly common, descriptive, and neutral term, and trying to rule it out of bounds. If you read the literature on cosmic fine-tuning and the anthropic principle, it becomes clear that the term is used by scientists as the best way to describe the condition of the universe, and without any hint or suggestion of theistic propaganda. Some examples:

In The Anthropic Cosmological Principle, physicists John D. Barrow and Frank J. Tipler write:

Hoyle realized that this remarkable chain of coincidences—the unusual longevity of beryllium, the existence of an advantageous resonance level in C12 and the nonexistence of a disadvantageous level in O16— were necessary, and remarkably fine-tuned, conditions for our own existence and indeed the existence of any carbon-based life in the universe.

These coincidences could, in principle, be traced back to their roots where they would reveal a meticulous fine-tuning between the strengths of the nuclear and electromagnetic interactions along with the relative masses of electrons and nucleons.

—John D. Barrow and Frank J. Tipler, The Anthropic Cosmological Principle (New York: Oxford, 1988) 253.

Barrow and Tipler aren’t using “fine-tuning” to promote theism. They are simply describing some of the fine-tuned conditions in the cosmos that make life possible. Similarly, cosmologist Martin Rees, Britain’s Astronomer Royal (and definitely not a theist), also uses “fine-tuning” in a purely objective, scientific fashion:

These six numbers constitute a “recipe” for a universe. Moreover, the outcome is sensitive to their values: if any one of them were to be “untuned,” there would be no stars and no life. Is this tuning just a brute fact, a coincidence? Or is it the providence of a benign Creator? I take the view that it is neither. An infinity of other universes may well exist where the numbers are different. Most would be stillborn or sterile. We could only have emerged (and therefore we naturally now find ourselves) in a universe with the “right” combination. This realization offers a radically new perspective on our universe, on our place in it, and on the nature of physical laws. . . . If you imagine setting up a universe by adjusting six dials, then the tuning must be precise in order to yield a universe that could harbour life.

—Martin Rees, Just Six Numbers: The Deep Forces That Shape the Universe (New York: Basic Books, 2001), 4 and 22.

In The First Three Minutes, Nobel-winning physicist (and atheist) Steven Weinberg writes about the fine-tuned nature of the cosmological constant:

There may be a cosmological constant in the field equations whose value just cancels the effects of the vacuum mass density produced by quantum fluctuations. But to avoid conflict with astronomical observation, this cancellation would have to be accurate to at least 120 decimal places. Why in the world should the cosmological constant be so precisely fine-tuned?

—Steven Weinberg, The First Three Minutes: A Modern View of the Origin of the Universe (New York: Basic Books, 1993), 186-187.

In The Grand Design, physicists Stephen Hawking and Leonard Mlodinow also write about the fine-tuning of the cosmological constant in Einstein’s general relativity equations, calling it “the most impressive fine-tuning coincidence” in cosmology. They go on to describe other fine-tuning problems in cosmology:

Most of the fundamental constants in our theories appear fine-tuned in the sense that if they were altered by only modest amounts, the universe would be qualitatively different, and in many cases unsuitable for the development of life. . . . The emergence of the complex structures capable of supporting intelligent observers seems to be very fragile. The laws of nature form a system that is extremely fine-tuned, and very little in physical law can be altered without destroying the possibility of the development of life as we know it. Were it not for a series of startling coincidences in the precise details of physical law, it seems, humans and similar life-forms would never have come into being.

—Stephen Hawking and Leonard Mlodinow, The Grand Design (New York: Bantam, 2012), 160-161.

So, to answer the question “Am I being dishonest about fine-tuning?,” the answer is no. I’m using the term “fine-tuning” in exactly the same way physicists and cosmologists Barrow, Tipler, Rees, Weinberg, Hawking and Mlodinow use it. I’m not playing word games to force a preordained conclusion. I lay out the evidence, I tell you what I think it means, and you are free to draw a different conclusion.

One of the most annoying experiences I have on Twitter is when atheists who don’t understand my views accuse me of lying. Why would I lie? For one thing, I’m morally and ethically committed to the truth. For another thing, I’m convinced that the evidence stacks up on my side. I believe that if I honestly present the evidence, including the sources and footnotes, the evidence will speak for itself.

I hope you’ll examine the evidence rationally and skeptically. If you are intellectually honest, you’ll at least see that I have valid reasons for my views. You may not be persuaded. You may not agree with me. You may have some counter-arguments to toss my way. Please do. All I ask is that you think critically, challenge everything, demand evidence—then be willing to follow that evidence wherever it leads.

Darwin’s Holocaust? (Part 3 of 3)

Go to Part 1.

Continued from Part 2.

Christopher Hitchens wrote a book called God Is Not Great: How Religion Poisons Everything. As the title suggests, Hitchens blamed much of the evil in the world on religion. (For more insight into Hitchens’ views and where his thinking went wrong, see Lament for an Atheist—Part I and Lament for an Atheist—Part II. See also the video at Christopher Hitchens Makes a Startling Admission.)

Evolutionary biologist Richard Dawkins makes a similar case in The God Delusion. And it’s true that many atrocities, savageries, and cruelties have been committed in the name of religion: The Crusades, the Spanish Inquisition, the persecution of Galileo, the execution of Giordano Bruno, the Albigensian Crusade, Martin Luther’s rabidly anti-Semitic treatise On the Jews and Their Lies, the Salem Witch Trials, the 1066 Granada Massacre and other pogroms, the “Troubles” in Northern Ireland, the Lebanese Civil War, the Israel-Palestinian problem, Jonestown, India versus Pakistan, ethnic cleansing in Bosnia-Herzegovina, Jihad, 9/11, and on and on.

But does religion really poison everything? Well, it depends on how you define “religion.”

If, by “religions,” we mean the tribalistic societies that organize themselves around certain beliefs, rules, rituals, and traditions, and that often defend their beliefs through figurative or literal “holy wars,” then yes, I agree, that sort of religion has a distinctly poisonous history. (And by tribalism, I mean any social structure — including a religion or denomination — that prizes cultural conformity within the group and practices hostility toward those outside the group.)

But if, by “religion,” we mean a commitment to live according to the teachings of, say, the Sermon on the Mount — teachings that cut across the grain of our tribal instincts by commanding us to love our enemies, forgive those who sin against us, and pray for those who persecute us — then Christopher Hitchens was simply wrong. That kind of rational, selfless religion has never poisoned anything. In fact, in The God Delusion, Richard Dawkins writes: “Jesus, if he existed … was surely one of the great ethical innovators of history. The Sermon on the Mount is way ahead of its time. His ‘turn the other cheek’ anticipated Gandhi and Martin Luther King by two thousand years.”24

The Sermon on the Mount is the sort of religion that even Richard Dawkins can endorse. The compassionate, forgiving, anti-tribalist Christianity of the Sermon on the Mount really does exist, and is often found right alongside the corrupt, institutional religiosity that Jesus of Nazareth confronted and condemned throughout the gospel accounts.

Jesus seemed to know in advance that some of his so-called “followers” would corrupt and betray his message. He predicted that a day would come when many supposed “Christians” would say to him, “Lord, Lord, did we not prophesy in your name, and in your name drive out demons and perform many miracles?” And he said his reply to them would be blunt: “I never knew you. Away from me, you evildoers!”25

Hypatia, a woman  of Alexandria in Roman Egypt, was one of the leading scholars of the classical age. She was famed as a mathematician, astronomer, and public speaker, and she taught at the Great Library of Alexandria. Unfortunately for Hypatia, she also threatened the political power of Cyril, the corrupt Christian archbishop of Alexandria. In AD 415, Cyril sent his aide, known as Peter the Reader, to recruit a mob of monks to assassinate Hypatia. The monks ambushed her in her chariot, stripped her naked, dragged her through the streets to the Caesareum church, where they killed her, defiling their own house of worship with her murder. They tore her to pieces, then burned the body parts outside of the city. The stated rationale for Hypatia’s grisly murder was that “she beguiled many people through Satanic wiles” — but the true motive was Cyril’s lust for power.26 No doubt, Jesus would say to Cyril, Peter the Reader, and the murderous monks, “I never knew you. Away from me, you evildoers!”

The Crusaders swept through Europe and into the Holy Land, slaughtered Jews and Muslims, pillaged and burned entire villages, raped women and put infants to the sword. They exhibited the heads of their slain enemies on stakes. Wild tales of miracles circulated among the Crusaders, bolstering their morale as they committed horrific atrocities under the banner of the cross. It’s no wonder that radical Muslims to this day identify all Christians as “Crusaders.”

Tomás de Torquemada was the first Grand Inquisitor of the Spanish Inquisition in the fifteenth century. Known as “the hammer of heretics,” Torquemada “enthusiastically supported the use of torture during interrogations,”27 and reportedly sent at least 2,000 supposed “heretics” to be burned at the stake. Yet if you compare Torquemada’s “enthusiastic” actions with the teachings of Jesus, you have to wonder: Who is the true heretic — Torquemada’s victims, or Torquemada himself?

Corrupt, tribalist, institutional religion is rife with human evil. To all those who torture, kill, rape, molest, seduce, and steal under the cloak of religion, the one who preached the Sermon on the Mount undoubtedly says, “I never knew you. Away from me, you evildoers!”

But the religion of the Sermon on the Mount, the religion endorsed by Richard Dawkins, is another thing altogether. That religion has produced some of the finest achievements of our civilization.

Take, for example, our healthcare system. Compassionate religion has blessed the world with the creation of hospitals. In the Middle Ages, religious orders of monks and nuns ran the first hospitals in Europe. In medieval France, a hospital was called a hôtel-Dieu, a hotel of God.

Or, consider how religion has promoted education. Priests and monks preserved civilization and learning through the Dark Ages. The church also invented institutions of higher learning. In medieval times, writes historian Lowrie J. Daly, “there were no great state-supported educational systems, nor even solitary schools. Practically speaking, the Church was the only institution in Europe that showed consistent interest in the preservation and cultivation of knowledge.”28

The first university in the world was at Bologna, Italy, founded around AD 1088 or earlier; next was Oxford, founded around 1096; the University of Salamanca, Spain, founded circa 1130; the University of Paris, circa 1150; and Cambridge, circa 1209. We don’t know the exact date any of these great universities were founded because they all had modest, unheralded beginnings as cathedral schools, taught by clerics.

Religion practically invented science as we know it. Medieval church clerics studied empirical phenomena and catalogued their findings. The study of science came naturally to the religious mind, because the early clerics believed that a rational God had created a orderly world that could be comprehended by human reason. Here are a few of those early clergy-scientists:

• Thierry of Chartres (died c. 1150) wrote and taught at a cathedral school at Chartes, France. In his Hexaemeron, he proposed a cosmology with similarities to the Big Bang and features of cosmic evolution.

• Robert Grosseteste (c. 1175-1253) was the Bishop of Lincoln and an Oxford scholar credited as the first mathematician and physicist of the Medieval era. Science historian Alistair Crombie called him “the real founder of the tradition of scientific thought in medieval Oxford.”29

• Albertus Magnus (c. 1200-1280) was a German Dominican friar who advocated the teaching of reason and science in the church. He catalogued thousands of insights and observations in logic, medicine, chemistry, and astronomy.

• Roger Bacon (c. 1214-1294) was a Franciscan friar known as Doctor Mirabilis (“wonderful teacher”) because he advocated the study of nature through the empirical method.

• Thomas Aquinas (1225-1274) advocated “natural theology” and “natural law,” rooted in reason as well as biblical revelation.

• French priest Jean Buridan (c. 1300-c. 1358) was one of the world’s earliest true physicists, recording observations that led to a modern understanding of inertia and momentum. In De Caelo et Mundo, he proposed an early version of the Copernican model of the cosmos — 200 years before Copernicus.

As the Middle Ages gave way to the Renaissance, great scientific minds continued to seek out the laws by which a rational God had designed an orderly universe. Johannes Kepler envisioned God as the Great Mathematician, and he went on to systematize the laws of planetary motion that bear his name. Michael Faraday saw God as the Great Physicist, who laid down laws for Faraday to discover in the fields of electricity and electromagnetism. Isaac Newton saw God as the Cosmic Engineer, and his faith in a rational God drove him to discover the laws of gravitation, motion, and mechanics.

As Paul Davies observes, “The very notion of physical law is a theological one in the first place, a fact that makes many scientists squirm. Isaac Newton first got the idea of absolute, universal, perfect, immutable laws from the Christian doctrine that God created the world and ordered it in a rational way.”30 Faith in a rational God and a well-ordered creation brought modern science into existence.

And then there’s the field of social justice — and particularly the abolition of slavery. While it’s true that many slaveholders rationalized their cruel trade from the Bible, it’s also true that religion founded on the Sermon on the Mount helped bring slavery to an end. The slave trade in England was abolished largely due to the efforts of a prominent evangelical, William Wilberforce. The American abolition movement was led by the Quakers and such evangelicals as Charles Finney.

So Hitchens’ blanket statement that “religion poisons everything” couldn’t be more wrong. The Crusades and the Inquisition and the pogroms weren’t caused by the Sermon on the Mount or anything else said by Jesus of Nazareth — just as Charles Darwin was not the instigator of the Holocaust or the Holodomor.

Theoretical physicist Freeman Dyson explains the seeming paradox that, down through the centuries, religion has inspired human beings to commit acts of both incredible evil and amazing good. He writes:

We have seen terrible wars and terrible persecutions conducted in the name of religion. We have also seen large numbers of people inspired by religion to lives of heroic virtue, bringing education and medical care to the poor, helping to abolish slavery and spread peace among nations. Religion amplifies the good and evil tendencies of individual souls.31

When evil people want to do evil things — when they want to commit acts of murder, genocide, sadism, oppression, theft, or terror — they will grab any rationale to make their evil seem “good.” If it weren’t some twisted pretense of religion or a pseudo-scientific rationale, it would have been some other excuse. But the evil would have happened in any case.

There is no evil in the words of Jesus. There is no evil in the theory of evolution. The evil is in people — in human nature itself.

That’s what poisons everything.
