Overall Rating: 6/10
I initially became interested in reading Darwin’s Doubt: The Explosive Origin of Animal Life and The Case for Intelligent Design after listening to a podcast interview with its author, Stephen Meyer. I immediately found myself at philosophical odds with a variety of Meyers theses, but nonetheless reluctant to employ the reactionary Neo-Darwinian critiques of his project. Thus, I decided to take the time to work through his text before offering comments (as interviews and podcasts seldom permit a full account or nuance of a position).
Having now completed my reading, I must admit that the basic philosophical problems that I initially felt (to be explored below) still persist. Yet, the text also revealed itself to be clear, well organized, and in large sections quite compelling. I must partially exempt the final three chapters in which Meyer advocates for Intelligent Design from my praise. Of course, my distaste for these sections is unavoidably influenced by my broader distaste for Intelligent Design theories (for reasons, again that will be clarified below), but I also found the writing itself to deteriorate during these passages; Meyer’s tone became defensive, the considerable citations and references to experimental work disappeared, and the arguments lost the clarity exemplified by the earlier sections of the work. One must not take these criticisms too strongly though, as the first sixteen chapters of the work truly are well written and interesting. Meyer presents considerable evidence that Neo-Darwinian theories (evolution by mutation) are insufficient to account for the speed and variety of evolutionary development, particularly during the infamous “Cambrian explosion.” This argument is strengthened by his use of multiple independent strains of evidence, including: fossils, genetics, and mathematical/computational models (among others). While I am not myself experienced in the field in order to fully judge the accuracy of all of his claims, he does offer considerable reference and citation to fully accredited and peer-reviewed scientific work (avoiding the common ID trap of only citing ones supporters). That being said, I would like here to focus upon the final section of his text, his presentation of ID as a possible answer to the dilemma of the Cambrian explosion, and offer two critiques.
* * *
First, and speaking here of Intelligent Design more broadly, I believe that a Kuhn’esque (see: Thomas Kuhn: The Structure of Scientific Revolutions) critique of Meyer’s conception of science may be in order. Specifically, Meyer appears to insufficiently register the “paradigmatic” structure of evolutionary theory. For Meyer, the incapacity of evolutionary theory to account for “everything” constitutes a rebuttal of the very scientific validity of the paradigm as a whole. Yet, as Kuhn rightly recognizes, the value of a paradigm is not its capacity to answer questions (though it certainly must do this with regularity), but more importantly its capacity to open up a space for questioning. A paradigm, while it is correctly functioning, will necessarily include a variety of unanswered questions. But, rather than constituting a failure of the paradigm, it is these gaps that provide the impetus and possibility of growth and discovery. A theory that provided a total picture would be incapable of generating further scientific research.
That being said, it is also worth noting that Kuhn is keenly aware of the importance of the “crisis,” that moment when an unavoidable impasse disorients a paradigm to such an extent that a new paradigm is necessitated. Could Meyer be identifying a crisis in biology, a crisis stimulated by the Cambrian explosion? Perhaps. But, I would also suggest that the answer to this crisis can not be Intelligent Design, again for a Kuhn’ian reason. The fatal flaw of Intelligent Design, I would suggest, rather than a lack of evidence or its factual incorrectness (both of which may very well also be the case), is its incapacity to function as a viable paradigm. Intelligent Design, while it ostensibly provides answers, fails to open up a space of further inquiry. Intelligent Design does not problematize, but rather, stifles problematization. Thus, while I would be wary to unambiguously support the assertion that “Intelligent Design is NOT science” (as this position is largely ideologically driven, and depends upon a clear identification of “science” that is generally either unspoken or insufficient), I would suggest that Intelligent Design is an insufficient paradigm, a scientific dead-end.

My second critique concerns Meyer more specifically, but also has consequences that extend into biology as a whole. Meyer summarizes his Intelligent Design argument as follows:
“Thus, based upon our present experience of the causal powers of various entities and a careful assessment of the efficacy of various evolutionary mechanisms, we can infer intelligent design as the best explanation for the origin of the hierarchically organized layers of information needed to build the animal forms that arose in the Cambrian periods.” (366)
Or, arranged as a syllogism, this argument might be restated:
- The natural world, in particular animal life, is structured by a variety of complex forms of information (DNA, RNA, epigenetic information, dGRNs, etc.).
- All know forms of information are the product of consciousness or intelligence.
- Therefore, animal life is most likely the product of intelligent design. 1
I would like to suggest, perhaps controversially that, given the presuppositions of modern evolutionary theory, that this syllogism may be completely justified. The common critique of Intelligent Design by evolutionary theorists generally involves an attack on the second premise. Natural selection, or some related mechanism, it is argued, permits the arrival of complexity, merely “apparent design.” Thus, it is said, the second premise’s claim that only conscious activity generates information is unjustified. Yet, I believe that Meyer is correct to clearly demarcate between mere complexity and information. Critics, he rightly argues, do not “seem to understand the importance of specified information, as opposed to ‘complicated things,’ as a key indicator of design” (393). Yet, by granting the connection between information and design, one does not therefore have to affirm the consequence of the total syllogism.
Rather, I would like to suggest, the key to dismantling the Intelligent Design argument is to challenge that premise that both Darwinians and ID’ers agree upon, the first premise. As Meyer illustrates throughout the entirety of Darwin’s Doubt, the notion that DNA and epigenetic data are best understood as “information,” is a presumption that saturates the entirety of biology. This appears nowhere more clearly than in computational models, but is also evident across the spectrum of academic biology. Perhaps, it might be suggested, that rather than constituting a radical break with the biological sciences, ID is merely the clearest manifestation of biology’s own flawed axiom.
In the work of Gilles Deleuze, this sort of misstep is understood as overcoding, the process by which the category of one “strata” of reality is extended across other “strata.” The clearest example of overcoding, for Deleuze, is the “linguistic turn” of 20th century philosophy. Here, the fact that language was able to describe or speak about all strata, was misunderstood as evidence that language constitutes all levels of reality. In 20th century philosophy, the linguistic strata overcoded all other strata.
Is it possible that the attribution of the category “information” (a definitively human, intelligent strata) to decidedly non-human, pre-intellectual strata is just such an overcoding? It is worth noting that while Deleuze’s “10,000 B.C.: A Geology of Morals” in A Thousand Plateus speaks at length of genetics, it resists throughout the notion of DNA as a language or as information. “That is why,” Deleuze insists:
“[Francois] Jacob is reluctant to compare the genetic code to a language; in fact, the genetic code has neither emitter, receiver, comprehension, nor translation, only redundancies and surplus values. […] This property of overcoding and superlinearity explains why, in language, not only is expression independent of content, but form of expression is independent of substance: translation is possible because the same form can pass from one substance to another, which is not the case for the genetic code, for example, between RNA and DNA chains.”
Perhaps, then, the moral of Darwin’s Doubt, and the Intelligent Design movement as a whole is the necessity of thinking genetics as such, no longer under the all-too-human categories of information, categories which cannot help but bear the baggage of intelligence and design. But the form that such an alternate conception of genetics might take is beyond this author, or at least beyond this post.
What are your thoughts, should genetics move beyond the language of information?
(Please, if you comment, avoid vitriolic anti-ID or anti-Evolution rants, I couldn’t be less interested in either)
1. The use of “most likely” is intentional, as it is the distinguishing factor of “abduction” (as distinguished from deduction and induction in the work of Charles Pierce, who remains influential not only upon Meyer, but upon the scientific tradition as a whole) and allows its arguments to be distinguished from the fallacy of “affirming the consequent.”
