Signature in the Cell
There is a Mind who was before all things and through whom all things are held together. Hence, I believe in intelligent design. But am I in the Intelligent Design (ID) movement? No.
The recent book, Signature in the Cell, by ID movement leader Stephen C. Meyer, illustrates why.Meyer holds a Ph.D. in philosophy from the University of Cambridge and is an expert in the philosophy of science. Admittedly, I am only an amateur in his area of expertise, but there were times as I was reading his book, when I was enthralled by the highly articulate explanation of how the tools of scientific logic enable us to become quite certain about the cause of natural events in the distant past. Similarly, his discussion of attempts to meaningfully define science was outstanding. He showed how the term has taken on new meaning based on practice. Today, as it is carried out by almost all practitioners, science has become synonymous with methodological naturalism. Meyer may have been overly optimistic when he wrote, “recently however, this [definition] has begun to change as more scientists are becoming interested in the evidence for intelligent design” (p. 437). Still, I enjoyed his discussion of the political and philosophical maneuvers of those with a vested interest in how this term ought to be defined. This is Stephen Meyer at his best. He is very effective in communicating philosophical issues to a general audience. Perhaps it is no surprise then, that a world-class philosopher, Thomas Nagel of New York University, recommended Signature in the Cell to The Times Literary Supplement as one of the best books of 2009.It is important to emphasize, however, that the Intelligent Design movement is not purported to be philosophical or religious in nature. The leaders, including Stephen Meyer, emphatically declare this is a scientific movement and it needs to be judged on the quality of its science, not its philosophy or theology. So Meyer has expanded his extensive reading list to include numerous journal articles and books within the field of biochemistry, molecular biology and genetics. His purpose has been to assess the quality of the scientific interpretations of the data as it relates to the origin of the information inside of cells. He has reached the conclusion that the sciences of biochemistry, molecular biology and genetics have come to a dead end and that the only reasonable scientific explanation now is that the information inside of a cell is the product of an external mind.Many scientists think that as life began, its source of information was found in RNA molecules. There are specialized reasons for this, which are not germane to the point I want to make. Suffice it to say, however, that Meyer suggests that the two different conditions for making two of the key building blocks that characterize an RNA molecule are incompatible (p. 303). In other words, the conditions under which one building block could have been synthesized on the early earth would have resulted in the destruction of the second building block, and vice versa. Since there is no way that both could have been produced simultaneously on a primitive earth, Meyer declares that RNA could not arise without the input of a mind. As he was writing these words, however, some elegant experiments were taking place at the University of Manchester that showed there is a way, a very feasible way that both building blocks could have been produced through natural processes.1
In Chapter 14, as Stephen Meyer brings his discussion about the feasibility of RNA’s role as the early storehouse for cellular information to a conclusion, he recalls a twenty year old conversation with a philosophy professor about origin-of-life-research: “The field is becoming increasingly populated by cranks. Everyone knows everybody else’s theory doesn’t work, but no one is willing to admit it about his own.” Following this statement, Meyer fast-forwards into the present, and writes of his own assessment of the field twenty years later: “I found no reason to amend these assessments” (p. 322). As a geneticist, I am taken aback by this assessment. The work he had just been discussing is the work of Jack Szostak who was awarded the Nobel Prize a few weeks ago. I’ve heard Dr Szostak speak a number of times. He is no crank. He is widely regarded as a brilliant mind. Read his Scientific American article for yourself (see footnote, below), you’ll see he is also very frank about the strengths and weaknesses of his current thoughts about life’s origins. Also, his work is by no means at a standstill. Only a philosopher, I suppose, or someone else quite naïve about how science proceeds at a lab bench would be able to make such an assessment.
Immediately prior to Meyer’s assessment about cranks in the field of origin-of-life-research, he had also been discussing the work of Gerald Joyce of The Scripps Research Institute. I have also been privileged to hear Dr. Joyce speak on at least three occasions. He, like Szostak, is widely regarded by biochemists and molecular biologists as brilliant. Like Szostak, I find that his discussion of the strengths and weaknesses of the RNA world model is cautious. He knows there are many unanswered questions, but he has made great strides at answering some of them. At the time of writing Signature of the Cell, Dr. Meyer correctly concluded that no RNA molecule had ever been evolved in a test tube which could do more than join two building blocks together. However, while the book was in press, Gerald Joyce and Tracey Lincoln published an article in Science in which they demonstrated that evolved-RNA can take on a second function, the all-important replication activity. In just 30 hours their collection of RNA molecules had grown 100 million times bigger through a replication process carried out exclusively by evolved RNA molecules. So another dead-end pronouncement by Meyer was breached even while the book was in press.
I want to give one more example which demonstrates Meyer’s disappointing tendency to reach premature conclusions based on his unsuccessful attempt to move from philosophy into genetics, biochemistry and molecular biology. Dr. Meyer evaluates the work of the population geneticist, Michael Lynch of Indiana University. He points out the Lynch has proposed that “the structure of the genome can be explained by a neutralist theory of evolution based mainly on genetic drift” (p. 470). Meyer concludes in just a sentence or two that Lynch is wrong and that genetic drift is less likely than natural selection. Again, I am very puzzled by this conclusion in what is purported to be a science book which is examining scientific data. Lynch is one of the finest population geneticists in the world. What experiment or calculation has Stephen Meyer done to put himself in a position to tell Michael Lynch which of two possible scenarios is more likely? Yet he does this in a single sentence.
Signature in the Cell is by most accounts considered to be a highly successful book. From a philosophy perspective, it is considered by at least one leading philosopher to be one of the best books of 2009. From a religious perspective, Meyer, on the basis of this book, has just been declared “Daniel of the Year” by the widely read evangelical periodical World Magazine. From the public persona perspective it has sold very well—Amazon.com had it on one of its top ten lists for the 2009 best sellers.
However, the book is supposed to be a science book and the ID movement is purported to be primarily a scientific movement—not primarily a philosophical, religious, or even popular movement. Meyer argues throughout the book that his theory about the origin of information is scientific, not religious. He makes it clear that he wants it to be considered on its scientific merits alone. I am comfortable with this. Let it be evaluated on the basis of its science. Like him, I believe in intelligent design. However, I am also a scientist. So I need to evaluate this book in the way that he calls all of us to do, as a work of science. I must consider whether this philosopher, this Christian brother, this best-selling author, and this leading debater has been successful at analyzing the data of the world’s leading scientists—people who have given their careers full time for many years to asking (and answering) very sophisticated questions about whether material causes have created information.
There is no question that large amounts information have been created by materialistic forces over the past several hundred million years. Meyer dismisses this without discussing it. What about at the very beginning, 3.5 billion years ago? Everyone doing the science, Meyer notwithstanding, would say the jury is still out. There are some very elegant feasibility experiments going on at the present time. However, it is far too early for a philosopher to jump into the fray and declare no further progress will be made and that this science is now dead. If the object of the book is to show that the Intelligent Design movement is a scientific movement, it has not succeeded. In fact, what it has succeeded in showing is that it is a popular movement grounded primarily in the hopes and dreams of those in philosophy, in religion, and especially those in the general public. With all due respect for the very fine people associated with the ID movement, many of whom I have met personally and whose sincerity I greatly appreciate, our hopes and dreams need to be much bigger than this. The science of origins is not the failure it is purported to be. It is just science moving along as science does—one step at a time. Let it be.
