Q&A: Intelligent Design Through Evolution — This Is an Illogical Claim
Intelligent Design Through Evolution — This Is an Illogical Claim
Question
The idea that from above someone “guided” evolution is an approach that tries to have it both ways: to enjoy the scientific explanations of evolution while at the same time attributing mystical meaning to them. But the human body itself dismantles that claim from every direction.
If there were intelligent design, how is it possible that we were born with such a dangerous birth system?
Why is the baby’s head almost too large to pass through the birth canal?
Why did women suffer throughout most of history from maternal mortality simply because of a pelvic structure that had to be adapted to upright walking?
And how is it that our nervous system is full of ridiculous detours, like the vagus nerve looping around the neck instead of going straight to the throat?
Evolution explains all this perfectly:
It is a compromise between a huge brain and a narrow pelvis, between an ancient ape-like structure and the demand for upright posture.
Evolution does not plan — it improvises. It patches one fix on top of another, under constraints, mistakes, and historical structures that cannot simply be “redesigned.”
Intelligent design, by contrast, cannot explain why the designer chose poor solutions when there were countless better ones.
There is no engineering, biological, or moral reason to create a birth system that causes death, a spine that falls apart, eyes built backward, teeth that do not fit the size of the jaw, or a baby born so extremely helpless.
Evolution fits reality.
Intelligent design fits only the desire to protect a preexisting faith.
Answer
First of all, the thesis of intelligent design did indeed arise in order to protect faith. There is nothing wrong with that. If you believe for good reasons (even apart from evolution), then when you see something that seems contradictory you try to reconcile it. That is what people do in science too, and in every other field. You can look here for my discussions about judging favorably and Occam’s razor, among other things.
Secondly, evolution does not compete with intelligent design. It is a result of it. Without it, evolution is not an explanation, because it itself relies on a very special system of laws for which there is no explanation without an intelligent designer.
From this you can understand that your description of intelligent design is mistaken. We are not talking about close divine accompaniment. God created a system of laws, and it produces evolution. He of course thought of that in advance.
Even so, your argument about why this is not perfect is not difficult. See my columns on evil in the world. There are constraints that even the Holy One, blessed be He, cannot bypass. If He wants a world with rigid laws that will produce evolution and life, it is not certain that He has a more perfect way to do so (a way within which phenomena like the ones you described would not appear). The burden of proof is on the one who raises this objection against Him. If you wonder why He did not choose a more complete route, show that such a route exists at all.
And in conclusion, your objection does not fit logic, whereas faith does. The difficulties you raised fit only the desire to defend atheism at any cost.
Discussion on Answer
I think you missed a critical point in this whole “intelligent designer” business. The claim is not “look what a perfect creation and perfect creatures,” but rather “look what a complex creation and complex creatures.” True, you can ask why and for what reason there are flaws in these creatures, but there could be any number of reasons for that (from heavenly considerations to the possibility that science still has not discovered everything).
Even if, for the sake of argument, we assume that your philosophical arguments in favor of an intelligent designer are persuasive, that still does not solve the problems I raised. A general philosophical conclusion about the existence of a designer does not explain why the product looks like a series of constraints, compromises, and poor engineering. A philosophical argument can at most claim that there is a designing entity, but it gives no answer at all to the question of why the design in practice looks exactly like what we would expect from a system that develops itself through cumulative evolution, and not like the handiwork of an all-powerful being. That gap does not disappear because of a philosophical conclusion. It requires a real explanation for the structure of the body, and the points I raised remain in place even if one accepts your basic premise. A metaphysical conclusion cannot replace dealing with the findings themselves, and certainly cannot impose on them an interpretation contrary to what they actually show.
You write that evolution is a result of intelligent design and therefore there is no conflict here. But that is simply begging the question. You take a natural mechanism that fully explains the compromises, patches, failures, and constraints found in the human body, and then automatically attach God to it as the one responsible. That is not an explanation but a faith-based framework imposed on reality regardless of what is actually happening in reality. My argument dealt with the body’s mechanisms themselves and with the built-in design failures within them. You are not dealing with them in their own right, but only through the principle that God must be involved, and therefore no finding can pose a challenge. That is not engagement; it is a declaration.
When you say there are constraints that God cannot bypass, you are presenting a much more problematic position. Constraints? What do they stem from? And if God is subject to them, then how is He different from a force of nature? And if He is not subject to them but chose not to bypass them, then that is a conscious choice of a flawed design that endangers life and produces unnecessary suffering. Both possibilities are problematic. You are trying to rescue intelligent design with the excuse that every failure is a constraint, but that is really an admission that the design is not good, only that there was no choice. That is not an answer for intelligent design. It is an admission that nature improvises and that God is somehow supposed to stand behind that improvisation. Is that really the path you want to defend?
As for your claim that I need to show that a better way even exists: the fact is, we do know better ways. Nature itself shows them. There are animals with better eyes than ours, without a blind spot. There are creatures with a birth structure many times safer than that of humans. There are nerves that travel in a direct route and do not make a meter-long detour like the vagus. There are skeletal systems suited to upright posture without vertebrae breaking down. There are animals born functioning almost immediately and not completely helpless. Countless better engineering solutions already exist right now. So how can one say there is no better way when actual examples are right in front of our eyes?
And when you demand to see a more complete and better-planned route, you are in fact admitting that every weak point I raised really does look problematic; you are just asking for a complete redesign. That is exactly the point. Evolution cannot perform a redesign. It works with what it has. An intelligent designer, by contrast, should be able to do that. And if an intelligent designer had to rely on historical patches and evolutionary limitations, then what is the difference between him and evolution itself? Intelligent design loses its meaning here. We do not need to invent solutions. Nature and engineering already offer alternatives. The real question is why a designer chooses the inferior alternative when a far better one is available.
And finally, your claim that these difficulties fit only a desire to defend atheism is just rhetoric. It is not a substantive answer. What difference does my motive make? A dangerous birth system does not become safer because of faith. A nerve that takes an unnecessary detour does not become more logical because of a theological motive. An eye that works contrary to engineering logic does not become more designed because it can be wrapped in a narrative. The findings remain what they are, and you are simply trying to fit them into an interpretation meant to align with an existing faith. That is personally legitimate, but it is not a substantive answer. It is not a response to intelligent design, nor is it a real engagement with the criticism I presented.
