Darwinism, Dawkins, and Complex Designers


Complexity and design seem to be infused into the very elements if life. Francis Crick, winner of the Nobel prize for his co-discovery of the structure of DNA, famously said "Biologists must constantly keep in mind that what they see was not designed, but rather evolved."1 Indeed, the strong map of design in the living creatures of the earth seems at first blush so strong that the scientists themselves have a hard time describing them without using vocabulary that implies design.

Richard Dawkins dismisses the appearance of the complex, organized features of life as pointing to a designer, though. In The Blind Watchmaker, Dawkins acknowledges that the complex nature of things like DNA are things that biologists "have difficulty explaining." Yet, Dawkins states that the organized complexity of either the DNA molecule or the molecular machinery used to replicate proteins in no way points to a designer, simply because what ever created it would need to be even more complex. He writes, "Of course, any God capable of intelligently designing something as complex as the DNA/protein machine must have been at least as complex and organized as that machine itself." This would then lead to looking for an even more complex designer of the designer and so on, regressing back to infinity. Thus, Dawkins concludes, to claim a designer "is to explain precisely nothing. "2

Alvin Plantinga, in his book Where the Conflict Really Lies: Science, Religion, and Naturalism, deftly takes Dawkins argument apart. He leads with a rather simple analogy showing why Dawkins' cleverness is unconvincing:
Design doesn’t explain organized complexity (says Dawkins); it presupposes it, because the designer would have to be as complex as what it creates (designs). Perhaps, therefore, Dawkins means to argue along the following lines: there are really just two explanations of life: unguided Darwinism and an explanation, guided Darwinism, perhaps, that involves design. But the latter is really no explanation at all. Therefore the only candidate is the former.

Here there are two problems. First, this argument doesn't depend on the facts of biology; it is substantially independent of the latter. Is it likely that Dawkins would be offering an argument of that sort? If so, why would he claim that it is "the Evidence of Evolution" that "Reveals a World Without Design"?

Set that problem aside for the moment; there is another and deeper problem with this argument. Suppose we land on an alien planet orbiting a distant star and discover some machine-like objects that look and work just like a 1941 Allis Chalmers tractor; our leader says "there must be intelligent beings on this planet-look at those tractors." A sophomore philosophy student on the expedition objects: "Hey, hold on a minute! You have explained nothing at all! Any intelligent life that designed those tractors would have to be at least as complex as they are!" No doubt we'd tell him a little learning is a dangerous thing and advise him to take the next rocket ship home and enroll in another philosophy course or two. For of course it is perfectly sensible, in that context, to explain the existence of those tractors in terms of intelligent life, even though (as we can concede for present purposes) that intelligent life would have to be at least as complex as the tractors. The point is we aren't trying to give an ultimate explanation of organized complexity, and we aren't trying to explain organized complexity in general; we are only trying to explain one particular manifestation of it (those tractors). And (unless you are trying to give an ultimate explanation of organized complexity) it is perfectly proper to explain one manifestation of organized complexity in terms of another. Hence it is not the case, contra Dawkins, that an explanation in terms of divine design is a nonstarter. Such an explanation doesn't constitute an ultimate explanation of organized complexity (if God is complex, nothing could constitute such an explanation); but it is none the worse for that. 3

God Allows Evil for the Good


There is a lot of evil in the world. I don't think that's controversial statement; most people would agree with it. But is the presence of evil good evidence to hold that God does not exist? That's what many atheists argue. They claim an all-good God could have created a world where no evil exits. Some have gone so far to argue that the fact that evil exists at all proves an all-good God doesn't.

But is this argument sound? I don't think so. In his book God, Freedom, and Evil, Alvin Plantinga lays out a very careful argument for why an all-good God would create a world where evil exists. Plantinga writes:
A world containing creatures who are significantly free (and freely perform more good than evil actions) is more valuable, an else being equal, than a world containing no free creatures at all. Now God can create free creatures, but He can't cause or determine them to do only what is right. For if He does so, then they aren't significantly free after all; they do not do what is right freely. To create creatures capable of moral good, therefore, He must create creatures capable of moral evil; and He can't give these creatures the freedom to perform evil and at the same time prevent them from doing so. As it turned out, sadly enough, some of the free creatures God created went wrong in the exercise of their freedom; this is the source of moral evil. The fact that free creatures sometimes go wrong, however, counts neither against God's omnipotence nor against His goodness; for He could have forestalled the occurrence of moral evil only by removing the possibility of moral good.1
I think this argument is correct. God valued significantly free creatures so much that he allowed them the ability to choose to do evil. I've previously offered a digestible example in a short video you can find here.

Answering "You'd be Muslim if You Were Born in Morocco"


Have you ever tried to argue for the truth of Christianity and had a person object that "The only reason you're a Christian is because you were born in a Christian country. If you were born in a Muslim nation, you'd be Muslim"? It's a common charge that sounds like it makes sense, but as Alvin Plantinga shows below, nothing follows from it. Plantinga writes:
There is an oft-repeated pluralistic argument that seems to be designed to appeal to reliabilist intuitions. The conclusion of this argument is not always clear, but here is its premise, in Hick's words:
For it is evident that in some ninety-nine percent of cases the religion which an individual professes and to which he or she adheres depends upon the accidents of birth. Someone born to Buddhist parents in Thailand is very likely to be a Buddhist, someone born to Muslim parents in Saudi Arabia to be a Muslim, someone born to Christian parents in Mexico to be a Christian, and so on.
As a matter of sociological fact, this may be right. Furthermore, it can certainly produce a sense of intellectual vertigo. But what is one to do with this fact, if fact it is, and what follows from it? Does it follow, for example, that I ought not to accept the religious views that I have been brought up to accept, or the ones that I find myself inclined to accept, or the ones that seem to me to be true? Or that the belief-producing processes that have produced those beliefs in me are unreliable? Surely not. Furthermore, self-referential problems once more 100m; this argument is another philosophical tar baby.

For suppose we concede that if I had been born of Muslim parents in Morocco rather than Christian parents in Michigan, my beliefs would have been quite different. (For one thing, I probably wouldn't believe that I was born in Michigan.) The same goes for the pluralist. Pluralism isn't and hasn't been widely popular in the world at large; if the pluralist had been born in Madagascar, or medieval France, he probably wouldn't have been a pluralist. Does it follow that he shouldn't be a pluralist or that his pluralist beliefs are produced in him by an unreliable belief-producing process? I doubt it. 1
Plantinga clearly points out the propensity to identify with a belief because one is born into a certain culture does nothing to prove the truth or falsity of that belief. Sure, if I were to  be born in aboriginal Australia five thousand years ago, I probably wouldn't believe men could ever construct flying machines, but such a belief would be untrue.

Further, it doesn't even follow that I would continue to be a Muslim if I was born into a Muslim culture. I have several friends who were born and raised Muslim, and yet they converted to Christianity when they saw its truthfulness. Thus, the objection falls flat on every point.

The Problem of Evil - The Free Will Defense Explained (video)




Why would God allow evil and sin to plague humanity? In this short clip, Lenny explains how God's desire to create creatures that truly love Him means that God must allow those creatures the freedom to choose. That means they could also choose to rebel. This clip is taken from a longer teaching entitled "How Could a Loving God Allow Evil in the World?"
