I think he's getting to the point that Darwinism is being replaced by newer theories of evolution, such as Punctuated Equilibria. The theory has changed quite a bit since Darwin's initial formulation.
In any case, back to kitten's statements. Kitten, I was explicitly talking about the IDers proposing an acasual intelligent creator. That is the logical flaw. Why should their proposed creator be acasual, when they rely on causality for the initial part of the argument? THe IDers argument starts from a aspecific baseline, I think we can agree on that (and I'm talking about the logical argument they represent, not the reasons and psychology behind it): IDers propose that many natural forms are too complex to have been designed without an external intelligence. This is an argument based on causality...they argue that complex forms must have had an intelligence cause, therefore there must be an intelligence behind them. Yet, the illogic comes in when they then argue that the compelx intelligence that would act as this cause does not require a cause. The argument looks like this:
If A, then B (postulate).
A (statement 1).
B (conclusion).
In the argument, A is "intelligent and/or complex forms." B is "intelligent designer." THe problem comes in because B is, by definition, a subset of A. Any intelligence (in the human sense, or the sense implied by IDers) is complex. Therefore, we can substitute in B for a int he previous statement, and we get:
If B, then B (postulate).
B (statement 1).
B (statement 2).
So basically, the argument boils down to "there's an intelligent designer if there's an intellgient designer." Because of the postualte they use to "prove" intelligent design, they cannot use the arguemnt for an acasual intelligence without nullifying their argument and, basically, making it the same argument as asserting a diety. They use causality to require a designer, then refuse to apply that same argument to the designer they require. They may mean God when they say designer, but that does not follow from the logic they use. One could just as easily posit computer intelligence or extra-terrestrials. There is no requirement that their designer be acausal, and that does not follow logically from their argument. By asserting that their designer can be intelligent and acasual, they violate the postulate they use to calim that humanity must have a designer. This is not logic.
That is what I was getting at before. I understand the IDer argument, both as they believe and as they put forth. I am attacking the argument they put forth, not their faith-based belief in an acasual diety-figure. I can show the flaw in their reasoning from the postulate they put forth.
