In his book, The God Delusion, Richard Dawkins attacks the idea of Intelligent Design (ID). In particular, he challenges Michael Behe’s idea that nature includes certain irreducibly complex mechanisms. Behe is a prominent ID proponent who believes that these mechanisms could not have been developed by Darwinian Evolution but instead contain elements that must have been designed.
Dawkins complains that Behe gives no arguments that any such mechanisms exist (Dawkins 157), but instead simply proclaims them by fiat (Dawkins 154). Behe is worshipping a God of the Gaps who is growing ever smaller as science is diminishing His realm (Dawkins 156).
Behe’s error, according to Dawkins, is that he cannot comprehend the analogy of “Climbing Mount Probable.” We observe complex mechanisms such as the eye. It seems like the Darwinian path from a lack of an eye to sight is a leap from one mountain top to another. Darwin shows us that there is a gradual path up the back of the mountain (Dawkins 147).
Dawkins argues against the irreducible complexity of eyes and wings. A cataract patient, having undergone surgery, can see enough not to bump into a tree. A creature with half a wing can use it to break a fall (Dawkins 149).
Behe proposed the bacterial flagellar motor as an irreducibly complex mechanism (Dawkins 156). Dawkins defines Behe’s concept thus: “The key to demonstrating irreducible complexity is to show that none of the parts could have been useful on its own” (Dawkins 158). Dawkins deals his coup de grace, revealing information of which Behe was apparently ignorant. Dawkins explains that protein molecules found in the flagellar motor are similar to the ones used by bacteria in the Type Three Secretory System (TTSS). “To the evolutionist it is clear that TTSS components were commandeered for a new, but not wholly unrelated, function when the flagellar motor evolved.” (Dawkins 159)
Dawkins finds ID to be self-defeating. It argues for the existence of God as a matter of probability. Dawkins observes, “However, statistically improbable the entity you seek to explain by invoking a designer, the designer himself has got to be at least as improbable.” (Dawkins 138) He goes on, “… however little we know about God, the one thing we can be sure of is that he would have to be very complex and presumably irreducibly so!” (Dawkins 151) Finally, “… the designer hypothesis immediately raises the larger problem of who designed the designer.” (Dawkins 188)
Dawkins quotes Daniel Dennett to make his point. Evolution counters one of the oldest ideas we have: “The idea that it takes a big fancy smart thing to make a lesser thing.” (Dawkins 142) Dawkins places this idea at the heart of the central argument of his book. (Dawkins 187)
Dawkins believes that Behe is embarrassingly ignorant of science, and quotes an attorney and judge to support his claim (Dawkins 157-160).
Dawkins complains that Behe and his associates are lazy and ignorant, and quotes an imaginary ID proponent to support his claim. “Don’t squander precious ignorance by researching it away. We need those gaps as a last refuge for God” (Dawkins 159). To further support his attack, he gives an imaginary argument about the irreducible complexity of the elbow joints of the fantastic creature, the lesser spotted weasel frog. Advocates of Intelligent Design fail to understand the power of Darwinism because they fill the gaps of our understanding of this non-existent creature with the machinations of God (Dawkins 152).
I did not make up that last argument. Dawkins actually quoted non-existent opponents. The biggest problem with arguing against imaginary people who say made up things about fictitious animals is that these things are not real. It just makes you look goofy. It is also an awful waste of ink and paper. Does Dawkins not realize that they cut down trees to print his books?
One of Dawkins’s most remarkable statements is that Behe does not give any arguments for why biological mechanisms are irreducibly complex. This is one of the most breathtakingly dishonest statements I have ever read. It may be possible to read Behe’s book, Darwin’s Black Box, and honestly disagree with the author’s conclusions. An honest reader could not agree, however, that Behe gives no arguments for his case.
One of the striking things about the book is that, while it is intended for a broad audience, he takes great effort to explain molecular biological functions in detail. In example after example Behe explains the specific machines he believes are irreducibly complex and why. This detail is integral to every chapter in his book because, as Behe explains, a key component to irreducible complexity is that it is complex.
Behe and Dawkins both like to use allusions. One of the things that distinguish The God Delusion from Darwin’s Black Box is that the latter is brimming with facts.
Another kind of dishonesty is incorrectly defining your opponent’s position. Dawkins claims that if any piece of a larger mechanism could be used for another purpose, that mechanism is not irreducibly complex. This is an egregious misrepresentation of Behe’s ideas.
Behe initially defined Irreducible Complexity as, “A Single System which is composed of several interacting parts that contribute to the basic function, and where the removal of any one of the parts causes the system to effectively cease functioning” (Behe 39).
Behe gave the example of a mouse trap with a base, catch, spring, hammer and hold down bar. If you were to remove any one of those parts, it would cease to act as a mouse trap. The evolution of the mouse trap would depend upon the simultaneous appearance of five random mutations. Natural selection would strike down any mouse trap that did not have five lucky, simultaneous, random mutations. The purpose of the extensive detail in Behe’s book was to demonstrate that a large number of biological functions were similarly irreducibly complex on a molecular level. The only difference was that the molecular machines were many times more complex than the simple mouse trap.
Behe, of course, never argued that the parts of an irreducibly complex mechanism could not be used for any other purpose. The base of a mouse trap might be used for as a paper weight. Some of the proteins found in TTSS can also be used in the bacterial flagellar motor.
Dawkins’s TTSS argument is not the surprise coup de grace he imagines, but was instead precisely the kind of critique Behe anticipated in his book. “Even if a system is irreducibly complex … one cannot definitely rule out the possibility of an indirect, circuitous route. As the complexity of an interacting system increases, though, the likelihood of such an indirect route drops precipitously. And as the number of unexplained, irreducibly complex biological systems increases, our confidence that Darwin’s criterion of failure has been met skyrockets toward the maximum that science allows” (Behe 40).
Dawkins use of Mount Improbable to explain Behe is strange. Very early in his book, Behe gave a very similar analogy. The point of Behe’s analogy was that what we actually observe in molecular biology and biochemistry are not a set of mechanisms that were susceptible to gradual construction from minute changes. Instead, we observe a vast number of irreducibly complex, highly sophisticated molecular machines, requiring inconceivably high numbers of simultaneous random mutations.
Dawkins has the luxury of climbing mount improbable as a gentle slope precisely because he is using the hypothetical. Behe actually discusses the details of molecular biology, and recognizes the incomprehensible leaps that have to be made to make each machine work.
There is another striking feature to Dawkins’s criticism of Behe. Dawkins spends a considerable amount of time demonstrating that the eye or a wing are not irreducibly complex. This may or may not be so. We are given to wonder, however, with whom he is debating. All of Behe’s arguments deal exclusively with life on the molecular level. Another form of dishonesty, is attributing to your opponents arguments they did not make.
It is very surprising that Dawkins devotes so much space to quoting attorneys and judges to combat Behe. If Dawkins was arguing a point of jurisprudence, this would be understandable. Dawkins’s complaint with Behe, however, is scientific and philosophical. Incidentally, the attorney in question represented an opposing party in a case in which Behe testified. Opposing council is often the least objective party on the planet as it concerns unfriendly witnesses. This matter is especially egregious, since Dawkins attempts (unsuccessfully) to humiliate his intellectual opponent through such specious means.
One problem with Dawkins’s work is that he frequently uses terms that he does not understand, such as “God of the Gaps”. This phrase might explain an ancient man observing lightning and perceiving it as evidence for God. There is a gap in the ancient man’s knowledge which he fills with God.
This is the opposite of what Behe is doing. He is observing molecular phenomenon that he can describe in great detail, and recognizing in it signs of design.
One idea that is central to Dawkins’s thinking is the assumption that the thing that started the universe and the origin of life must be simpler than the thing created. Dawkins clearly regards this as an argument of such force that it deals a death blow to any argument for God.
It is obvious that Dawkins does not have any friends. If he had, then someone would have taken him to one of those wonderful science fiction films wherein the captain and that fellow with the pointy ears runs into alien technology that makes horrible squid like monsters appear like beautiful women just long enough for them to eat the brains of earthlings. If Mr. Spoock had read Dawkins book, he would have said, “this device could not have been made by an evil 10 armed alien, since that evil alien would have had to have been more complex than the device.” In that case, the captain would have been eaten, the movie would have been over in ten minutes, and science fiction would have died as a genre.
It is curious that Dawkins finds such power in this argument. It is startlingly unscientific. In every instance I can imagine, the agent that designs and creates a device or system, is always more complex than the device or system. The prehistoric men that struck particular kinds of stones to make spear heads were more complex than the spear heads. The ancient men who built the first pyramids were more complex than their buildings. Leonardo de Vinci was more complex than the Mona Lisa. Even the space station, in all its massive complexity, is simpler than one member of the army of engineers that designed it.
Using Dawkins’s rule, every time we found a new ancient city, we would have to assume that it was created through erosion, earth quakes or storms. The agent that created the city will always be more complex than the city itself.
Dawkins invents a special rule for the designer of life, who must be simpler than the thing designed. This is, of course, not an argument, but a statement. Dawkins spends a great deal of time repeating the statement, but does absolutely nothing to defend it.
Dawkins says that God is more improbable than Darwinian evolution. Typically, when scientists discuss probability, they do some math. Dawkins presents none. He does, however, do a great job of misrepresenting Intelligent Design.
Intelligent Design is, at its most fundamental level, not an argument that God exists as a matter of probability. Central to the argument of Intelligent Design is that design is something that we can recognize. An explorer finds a flat stone with unrecognizable indentations. Is it erosion or writing from a previously undiscovered language? Another explorer discovers something made of a metal alloy. It also includes regular rotary grooves. Is this a previously unknown tool or evidence of unusual volcanic activity? In both cases, we would conclude that the stone and the tool were created by a designer.
Dawkins’s final argument is that Intelligent Design raises the larger problem of who designed the designer. The observant reader will immediately recognize several massive problems with Dawkins’s objection. Imagine we apply this criteria to all discoveries.
A team of explorers discover an island with things that look a lot like abandoned buildings and stone tablets that look a lot like writing in a previously unknown language. The explorer returns to London and explains that he has discovered a new people group. Dawkins is in the audience and asks, “Where did the people come from? How did they get on the island? Since you cannot answer these questions, you have not found a new people group. You have only discovered unusual seismic activity.”
If the explorer could explain that the group came on canoes, this discovery would be nullified because he could not explain from where they came. If he could explain from which continent they came, this discovery would be nullified because he could not explain how they got on that continent etc.
Using this criteria, science would be impossible. Darwinism would be untenable, since we do not know the origin of the first ancestral life form.
Dawkins has missed one of the most elementary principles in the philosophy of science. In order to recognize an explanation as the best, you do not need to have an explanation of the explanation.
Finally, Dawkins is miffed that his opponents have not argued against their own case. He complains that Intelligent Design has not explained who designed the designer. In as much as he is addressing theistic ID proponents, and theism is the target of his book, Dawkins is babbling incoherently. The classical theist is trying to prove that a God exists who is omnipotent, omniscient, omnipresent, uncreated and eternal. Dawkins is angry that ID has not disproved the last two attributes. If God had a designer, he would be neither eternal nor uncreated.
This would be like Behe complaining that Dawkins had not disproved the efficacy of natural selection.
I am not cherry picking obscure arguments peripheral to the main theme of Dawkins’s book. These are among the arguments he trumpets as his tour de force, central to his thesis. The poor logic Dawkins employs at the very heart of his book is disconcerting. His mammoth ignorance of the faiths that he attacks is troubling. It is, however, Dawkins’s blatant dishonesty that is shocking.
