AN INTELLIGENT REPLY TO INTELLIGENT-DESIGN CRITICS
By Hendrik van der Breggen
Several Record readers recently raised a flurry of criticisms concerning my article, “There’s an intelligent defence for intelligent design” (August 23), in which I deflated some philosophical objections to intelligent design as a scientific explanation of life’s origins. I would like to reply to two important and widely-held criticisms from that flurry, and I would like to do so in such a way that many of the minor and less-widely-held criticisms presented in the flurry are addressed as well. My hope is that thereby I could continue to encourage the public and the scientific community to give intelligent design a fair hearing.
Criticism 1: Intelligent design is not falsifiable or testable.
Reply: This is patently untrue. The intelligent design hypothesis predicts (retrodicts) that life’s origin is due to an intelligent cause, be it God or whomever. The hypothesis is falsifiable/testable because, in principle, evidence can be mustered to show that an intelligent cause was at work or not.
Significantly, intelligent design, though falsifiable in principle, has not been falsified in fact.
But don’t take my word for it. Consider the following comments from credible scientists and science reporters concerning the scientific community’s ongoing failure to explain life by non-intelligent causes.
Francis Crick (co-discoverer of DNA’s structure): “An honest man, armed with all the knowledge available to us now, could only state that in some sense, the origin of life appears to be almost a miracle, so many are the conditions which would have to be satisfied to get it going.” (Francis Crick, Life Itself: Its Origin and Nature [New York: Simon & Schuster, 1981], 88.)
Klause Dose (of the Mainz Institute for Biochemistry): “More than 30 years of experimentations on the origin of life in the fields of chemical and molecular evolution have led to a better perception of the immensity of the problem of the origin of life on Earth rather than to its solution. At present all discussion on principal theories and experiments in the field either end in stalemate or in a confession of ignorance.” (Klause Dose, “The Origin of Life: More Questions Than Answers,” Interdisciplinary Science Review 13 [1988]: 348.)
Paul Davies (theoretical physicist turned origin-of-life investigator): “[S]cientists are currently stumped…. The problem of how and when life began is one of the great outstanding mysteries of science.” (Paul Davies, The 5th Miracle: The Search for the Origin and Meaning of Life [New York: Simon & Schuster, 1999], 19, 27.)
Fazale Rana and Hugh Ross (a biochemist and astronomer reporting on a combined meeting of the International Society for the Study of the Origin of Life plus the International Conference on the Origin of Life): “Some 45 years of well-funded investigation have led to one dead end after another. The same intractable problems still remain, with no glimmering of resolution in sight.” (Fazale Rana & Hugh Ross, “Life From the Heavens? Not This Way…,” Facts For Faith 1 (2000): 11.
Nicholas Wade (New York Times science-writer summarizing the results of the scientific community’s attempt to explain the origin of life solely in terms of non-intelligent causes): “Everything about the origin of life on earth is a mystery, and it seems the more that is known, the more acute the puzzles get.” Wade adds: “The genesis of life on earth . . . remains an unyielding problem.” (Nicholas Wade, “Life’s Origins Get Murkier and Messier,” The New York Times [June 13, 2000], F1, F2.)
In other words, scientists (not philosophers) have demonstrated that non-intelligent causes are deeply problematic as explanations for life’s origin. Significantly, this means that attempts to falsify intelligent design have been made, and have been found wanting.
But this means too that nature’s prima facie evidence for intelligent design hasn’t been explained away. Nature’s apparent design remains.
But there is more. Intelligent design is also positively supported by scientific discoveries which show that biological life’s complexities are analogous to the effects of known intelligent causes.
For example, DNA is like a language/code. Even Bill Gates of Microsoft has observed that “DNA is like a computer program but far, far more advanced than any software we’ve ever created.” (Bill Gates, The Road Ahead, 2nd edition [New York: Penguin Books, 1996], 228.)
Also, the cell’s interior is like a factory (some say city) filled with highly complex and intricately coordinated machines—machines that are “like the machines invented by humans,” as even evolutionist Bruce Alberts, former President of the U.S. National Academy of Sciences, admits. (Bruce Alberts, “The Cell as a Collection of Protein Machines: Preparing the Next Generation of Molecular Biologists,” Cell 92 [February 6, 1998]: 291.)
Surely, evidence and good reasoning can test these analogies to effects of known intelligent causes
Thus, criticism 1—that intelligent design is not falsifiable or testable—does not weaken intelligent design.
(For more discussion about testing the analogies between, on the one hand, the universe’s fine-tuning for life, the molecular machines of the cell, and DNA’s code/language, and, on the other hand, the effects of known intelligent causes, see chapter 4 of my “Miracle Reports, Moral Philosophy, and Contemporary Science” [PhD dissertation, University of Waterloo, 2004]. Several copies of my dissertation are available at the University of Waterloo. For more discussion of testability, refutability, and predictability, see William A. Dembski’s The Design Revolution: Answering the Toughest Questions about Intelligent Design [Downers Grove, Illinois: InterVarsity Press, 2004], 280-290.)
Criticism 2: We know only of intelligent causes located in biological systems, so appealing to unembodied, nonphysical intelligence is a conceptual error.
Reply: There is no conceptual error. Empirically, we know that intelligent causes (apart from one’s self) exist because of their physical effects. This is plainly so with humans. However, from the fact that all human intelligent causes are located in biological systems, it doesn’t follow that all intelligent causes must be embodied. Whether we know empirically that an intelligent cause can exist unembodied (as, say, the cause of the big bang’s fine-tuning and life’s subsequent origin) depends on whether there are empirical effects that point to such a cause; not on prior stipulations or rulings that disallow such causes.
To rule that an unembodied intelligent cause cannot be a scientific explanation of effects which clearly point to such intelligence is to constrain science by a materialist philosophy that will not allow what may be the best explanation of the empirical evidence.

Should intelligent design be taught in public schools as a theory of life’s origins alongside the theory of evolution (where “evolution” is understood as not allowing for any influence of an intelligent cause)? Obviously, there is much controversy on this question, and much remains to be discussed. As scientists learn to consider the merits of intelligent design without being unduly influenced by a materialist philosophical bias, I think we can at least agree on this: Public school curricula should include good science instruction on evolution’s successes AND on evolution’s shortcomings.
In this regard, I recommend biologist Jonathan Wells’ book Icons of Evolution: Science or Myth? Why much of what we teach about evolution is wrong (Washington, D.C.: Regnery Publications, 2000).
