Reflections on Stanley Miller’s Death and Life

Even if you don’t recognize the name, you are probably familiar with his famous experiment. Virtually every introductory biology text describes the work Miller performed in the early 1950s. Miller showed that the primitive atmosphere of early Earth could, in principle, generate amino acids, one of the key building blocks of life.

Miller’s work was the first experimental validation of the Oparin-Haldane hypothesis and launched origin-of-life studies as an experimental research program. His success prompted scientists to conduct similar experiments in the quest to discover chemical routes to other critical biomolecules.

Implications of the Miller-Urey Experiment

Beyond its scientific impact, Miller’s work has had profound philosophical and even theological consequences. For many people, the generation of amino acids from simple chemical compounds thought to be present in early Earth’s atmosphere meant that life could originate all on its own without the need for a Creator. I’ve met many people who have struggled with their faith as Christians after learning about this experiment in high school and college biology courses. And I’ve known many nontheists who use this experiment as part of the rationale to reject belief in a personal God.

It’s probably safe to say that next to Charles Darwin, Stanley Miller has probably been one of the most disliked and maligned scientists within the Christian community. His work and, unfortunately, his reputation have been the subject of attack and ridicule by Christian apologists for the last half-century. For many Christians, Miller—like Darwin—embodied atheistic materialism. By attacking Miller—his character and his work—Christians saw themselves striking back against the threat they perceived from science.

Miller’s death has prompted me to reflect on how Christians often inappropriately view and treat scientists, particularly evolutionary biologists. We must reconsider the way we engage in apologetics and evangelism. The bottom line: If we ever want to effectively engage skeptics within the scientific community, we must avoid alienating them with our apologetics methodology. We cannot treat them as the enemy of the Christian faith, but rather must regard scientists as people occupying an important mission field. We need to look for opportunities to build bridges, not erect walls, as we present the Christian faith to them.

An Amazing Story

The behind-the-scenes story of the Miller-Urey experiment is remarkable in many respects, and provides an opportunity for Christians to affirm Stanley Miller and Harold Urey, in spite of the profound philosophical and scientific differences on life’s origin. These points of affirmation represent shared values and common ground that many scientists and Christians can stand on.

Miller conducted his famous experiment as a young graduate student at the University of Chicago. After hearing Nobel Laureate Harold Urey lecture on the current ideas about the early Earth’s atmosphere, he approached the eminent scientist and asked if he could join his lab and attempt to verify the Oparin-Haldane hypothesis. Urey initially declined out of concern for Miller’s future, viewing the work as too risky for a graduate student to pursue.

Miller persisted, however, and Urey reluctantly agreed. But in Miller’s best interest, Urey gave him a time limit to show progress on the project. The rest is history. Miller was able to generate amino acids and alpha-hydroxy acids from a simple mixture of gases in short order and later determined that the reaction mechanism was closely related to the Strecker Reaction.

In an act of selflessness, Urey insisted that Miller publish the work as the sole author, contrary to standard academic practices. (Usually the research advisor is listed as the author on all papers generated within his or her laboratory.) Urey’s name rightfully belonged on the paper submitted to Science, but Urey recognized the significance of Miller’s work and wanted him to be the full beneficiary. If Urey’s name had appeared on the paper, he would have taken all the attention away from Miller.

And what attention Miller received! When published in Science, Miller’s results met with instantaneous and worldwide excitement and fanfare. Both the New York Herald Tribune and New York Times wrote about Miller and his discovery on the same day that his paper appeared in Science. A short time later Time, Newsweek, and Life wrote about his work. At twenty-three years of age, Stanley Miller was suddenly propelled to worldwide fame.

Most graduate students are drawn to science because of their fascination with nature and a deep desire to understand how it all works. This allure provides the motivation to work long, hard hours in the laboratory. I am sure that this was true for Miller. Still, in the back of the minds of most young scientists resides the hope that their research will lead to a breakthrough so significant that it will propel them to worldwide fame. More often than not, this great expectation never happens.

But Stanley Miller lived the dream.

This story endears Miller and Urey to me. As a scientist, I can’t help but marvel at Miller’s accomplishments and impact on science as a young chemist. And as a Christian, I am impressed with the compassion and generosity Urey displayed toward Miller, and his sincere concern for the young scientist’s interests and career. This painfully reminds me that sometimes non-Christians do a better job at living out these Godly qualities than many Christians, including me.

Miller’s persistence and courage are to be admired as well, whether one is a Christian or not. As a young scientist, Miller pursued a question that many established scientists shied away from, because it was too risky. He was not dissuaded by a Nobel Laureate’s protests. As Christians, persistence and courage are two virtues that we need to strive for as we seek to live out our faith, particularly in pursuit of God’s calling on our lives. Miller’s life reminds me that sometimes non-Christians manifest these types of virtues to a greater extent than Christians.

A Poignant Encounter

The first time I saw Miller was at the 1999 meeting of the International Society for the Study of the Origin of Life (ISSOL ’99) held at the University of California, San Diego. Even though I disagree with the views Miller held about the explanation for the origin of life, I was thrilled to be in the presence of such an important figure. I saw him at a poster session, walking around the room reading and discussing the presentations with the participants.

It was clear that Miller was a mentor to many younger scientists, offering his insights and constructive feedback about their work and encouraging them. Miller willingly and selflessly invested himself into the lives of others, a quality that merits admiration.

The next time I saw him was at ISSOL ’02 held in Oaxaca, Mexico. My reaction was very different this time around. Instead of excitement, I felt a strong sense of sorrow and compassion for him. Miller was confined to a wheelchair and was clearly suffering from a debilitating sickness. He appeared feeble and required the constant attention of a caretaker. While other conference participants made their way to the veranda of the conference hotel to enjoy a coffee break or have lunch, Miller remained behind.

During the sessions, a special place was reserved at the front of the room for him. It was sad to see him wheeled in right before each session started, a constant reminder to all of us of the struggle he faced. Miller appeared to be in the last years of his life.

One particularly heartrending moment came during a session on prebiotic chemistry, when the session chairman pointed out during the introduction that Miller’s work was no longer relevant. He was quick to extend respect to Miller and qualified his assessment by emphasizing the work’s historical value, but the harm had been done. The painful reality was that Miller had devoted his life to understanding the origin of life and, at the end of his life, his most important contribution was no longer regarded as genuinely significant to the current paradigm.

At that time, I truly saw Miller as a human being, not as a caricature to be ridiculed or an embodiment of atheism to be assaulted. He was someone like me, confronted with disappointments and frustrations that arise from life’s challenges and difficulties so severe that they bring the ultimate questions about life’s meaning and purpose to the forefront.

Stanley Miller and the Gospel

As Miller reached the end of his life, was he troubled about his fate after death? Was he concerned about his life’s meaning and purpose? I have no way of knowing if he asked questions like this. But if he did, it would be hard for me to imagine that he would have turned to the Christian faith to see if it had any answers, if for no other reason than the vitriol spewed at him by Christians for the last half century.

Peter reminds us (1 Peter 3:15) that when we raise apologetics issues with non-Christians, it should always be with gentleness and respect. Tragically that has not been how Christians have treated Miller and other skeptics in the scientific community. I wish I could say that I have never been guilty of these offenses. But I am.

Stanley Miller’s death deeply saddens me.

Resistance to Science?

Wednesday, September 19th, 2007

Though there’s been no shortage of new reasons to believe, it seems that time to report them has been in short supply lately. In case you missed these recent gems, this week we present some of the best recent posts.

Photo of Jeff ZweerinkA few weeks ago, I discussed an article trying to understand the basis for adult “resistance” to science. I put resistance in quotes because the two prime examples of resistance the author cites involve the theory of evolution and Francis Crick’s idea that the mind arises solely from physical processes. Ironically, three new book reviews appeared in Science and Nature addressing these two areas.

The first reviewed Douglas Hofstadter’s book I Am a Strange Loop. Hofstadter argues for a completely materialistic explanation for the nearly universal perception that our minds exist at least somewhat independently of our brains. The explanation he posits is that

…our feeling of a conscious “I” is but an illusion created by our neuronal circuitry: an illusion that is only apparent at the level of symbols and thoughts…

David Sloan Wilson’s book Evolution for Everyone: How Darwin’s Theory Can Change the Way We Think About Our Lives attempts to explain the strangeness of human behavior in an evolutionary framework. Some of those odd behaviors include the fact that humans (1) have the only fully developed symbolic language on the planet, (2) cooperate and engage in elaborate task-sharing and reciprocal relationships with people we don’t know, (3) wear matching silly shirts at sporting events, (4) follow queues in an orderly fashion, (5) help the elderly, (6) give money to charity, and (7) disapprove of those who behave otherwise. The explanation Wilson posits for this “extreme sociality” of humans is that we evolved by group selection. The reviewer closes by asking

If our minds evolved to help us wade through the complexity of social life, to use groups for our own gain, and to help us rebound from ‘the slings and arrows of outrageous fortune’, which set of beliefs, on balance, will be more useful, religious ones (whether true or not) or a belief in natural selection?

Finally, David Linden’s book The Accidental Mind: How Brain Evolution Has Given Us Love, Memory, Dreams, and God argues that the functioning of the brain could not be designed because of its flaws. One point highlighted by the reviewer is that the “anachronistic junk” bestowed by evolution on our brains explains why our minds often distort reality and lead us to act foolishly.

What I find remarkable about these three books is that they all advance arguments that seriously undermine the assumption that we can trust the inferences drawn from our minds. According to Hofstadter, the idea of a mind (where reason and scientific thought reside) is an illusion developed by our brain. If, according to Sloan Wilson, the inferences drawn from our brain only function to increase survivability, there is no reason to suspect they are true. Linden’s book puts an exclamation mark on this last point.

I would argue that only Christianity provides a coherent worldview whereby we can rationally trust the inferences drawn from our mind. This argument from reason remains a potent reminder of naturalism’s weakness and of Christianity’s strength.

Thinking about Theistic Evolution

Tuesday, September 18th, 2007

Though there’s been no shortage of new reasons to believe, it seems that time to report them has been in short supply lately. In case you missed these recent gems, this week we present some of the best recent posts.

What is Theistic Evolution?

Theistic evolution (sometimes abbreviated TE) takes many forms but its general theme is that God used natural evolutionary processes to bring about his desired results concerning life on planet Earth, culminating in the appearance of human beings. Advocates of this position typically propose that God intervened directly (de novo, anew) at the beginning of the creative process (origin of the universe) but afterward worked solely through natural mechanisms to give rise to life and ultimately to humanity. Because the created order possesses built-in self-organization and transformational qualities, no further supernatural intervention was necessary as it moved through the evolutionary process.

Many who hold this position interpret the early chapters of Genesis as figurative, archetypal, or mythological in nature. Theistic evolution is also sometimes called “evolutionary creationism,” “fully gifted creation,” and “BioLogos.”

What difficulties are associated with Theistic Evolution?

While a number of prominent Christian scholars affirm theistic evolution, other evangelical scholars have identified a variety of scientific, theological, and biblical objections with the viewpoint. Three such criticisms will be outlined briefly:

  1. Some scientists argue that the challenges for a naturalistic explanation of the origin of life, like the sudden emergence of complex life-forms (such as at the Cambrian explosion), also apply to theistic evolution. Therefore, TE may not explain the discontinuities in the natural record in an adequate and persuasive manner.
  2. Some theologians suggest that theistic evolution’s view of God (a being who does not directly intervene in the universe after creation) comes closer to deism than to biblical theism (a God who not only creates, but continually intervenes and sustains). In other words, some think TE focuses upon God’s immanence in creation at the expense of his transcendent creative intervention, whereas biblical theism stresses the need to properly balance both of these critical divine attributes.
  3. Not only does Scripture seem to indicate that God has intervened directly in the creative process to create the first member of each kind of species (rejecting all such macroevolution), but the biblical text also seems to present God as creating Adam and Eve in a direct, special, and personal way (thus as authentic historical persons). Thus most evangelical textual scholars view the early chapters of Genesis as reflecting a genuine historical narrative.

For a presentation and defense of theistic evolution, see Howard J. Van Till, “The Fully Gifted Creation (‘Theistic Evolution’),” in J. P. Moreland and John Mark Reynolds, gen. ed. Three Views on Creation and Evolution (Zondervan, 1999) and Francis S. Collins TheLanguage of God (Free Press, 2006).
