Who designed the Designer?

Who designed the Designer:

The jist of the argument. (Get Dawkins actual words.)
The Universe is complex.
It is improbable (but not impossible) that a world like ours should exist by chance.
A god capable of designing the universe must be more complex than the universe itself.
If it is improbable that our universe should exist, it is even less probable that being who is more complex than the universe should exist.
Given Occam’s razor (the simplest explanation is to be preferred), it makes more sense to affirm the self existence of the universe, than to affirm the self existence of God.




Solutions


1) In the ordinary course of scientific or inquiry, not all explanations require explanations in order to have merit.

2) An explanation for an effect may indeed be greater (or more complex) than the effect itself.

3) God, in terms of knowledge (or knowing, or information) is more complex than the world of His creation, but is, in essence is radically simple. (God is not materially complex, or complex in the sense of composition of parts.)

The idea that God is more complex than the Universe of His Creation assumes a materialist understanding of who or what a god is. (And makes and arguement for Naturalism, by first assuming naturalism.)

4) God, by definition is not contingent, but is a necessary being. (God is Eternal)


(From a response by Alvin Plantinga)

Here Dawkins doesn't appeal to the usual anti-theistic arguments—the argument from evil, for example, or the claim that it's impossible that there be a being with the attributes believers ascribe to God.2 So why does he think theism is enormously improbable? The answer: if there were such a person as God, he would have to be enormously complex, and the more complex something is, the less probable it is: "However statistically improbable the entity you seek to explain by invoking a designer, the designer himself has got to be at least as improbable. God is the Ultimate Boeing 747." The basic idea is that anything that knows and can do what God knows and can do would have to be incredibly complex. In particular, anything that can create or design something must be at least as complex as the thing it can design or create. Putting it another way, Dawkins says a designer must contain at least as much information as what it creates or designs, and information is inversely related to probability. Therefore, he thinks, God would have to be monumentally complex, hence astronomically improbable; thus it is almost certain that God does not exist.

But why does Dawkins think God is complex? Now suppose we return to Dawkins' argument for the claim that theism is monumentally improbable. As you recall, the reason Dawkins gives is that God would have to be enormously complex, and hence enormously improbable ("God, or any intelligent, decision-making calculating agent, is complex, which is another way of saying improbable"). What can be said for this argument?


Not much. First, is God complex? According to much classical theology (Thomas Aquinas, for example) God is simple, and simple in a very strong sense, so that in him there is no distinction of thing and property, actuality and potentiality, essence and existence, and the like. Some of the discussions of divine simplicity get pretty complicated, not to say arcane.3 (It isn't only Catholic theology that declares God simple; according to the Belgic Confession, a splendid expression of Reformed Christianity, God is "a single and simple spiritual being.") So first, according to classical theology, God is simple, not complex.4 More remarkable, perhaps, is that according to Dawkins' own definition of complexity, God is not complex. According to his definition (set out in The Blind Watchmaker), something is complex if it has parts that are "arranged in a way that is unlikely to have arisen by chance alone." But of course God is a spirit, not a material object at all, and hence has no parts.5 A fortiori (as philosophers like to say) God doesn't have parts arranged in ways unlikely to have arisen by chance. Therefore, given the definition of complexity Dawkins himself proposes, God is not complex.


So first, it is far from obvious that God is complex. But second, suppose we concede, at least for purposes of argument, that God is complex. Perhaps we think the more a being knows, the more complex it is; God, being omniscient, would then be highly complex. Perhaps so; still, why does Dawkins think it follows that God would be improbable? Given materialism and the idea that the ultimate objects in our universe are the elementary particles of physics, perhaps a being that knew a great deal would be improbable—how could those particles get arranged in such a way as to constitute a being with all that knowledge? Of course we aren't given materialism. Dawkins is arguing that theism is improbable; it would be dialectically deficient in excelsis to argue this by appealing to materialism as a premise. Of course it is unlikely that there is such a person as God if materialism is true; in fact materialism logically entails that there is no such person as God; but it would be obviously question-begging to argue that theism is improbable because materialism is true.

So why think God must be improbable? According to classical theism, God is a necessary being; it is not so much as possible that there should be no such person as God; he exists in all possible worlds. But if God is a necessary being, if he exists in all possible worlds, then the probability that he exists, of course, is 1, and the probability that he does not exist is 0. Far from its being improbable that he exists, his existence is maximally probable. So if Dawkins proposes that God's existence is improbable, he owes us an argument for the conclusion that there is no necessary being with the attributes of God—an argument that doesn't just start from the premise that materialism is true. Neither he nor anyone else has provided even a decent argument along these lines; Dawkins doesn't even seem to be aware that he needs an argument of that sort.
