If you (re)define "irreducibly complex" as "painted blue," then of course you will get different answers about what objects are IC than if you use the actual definition.
I'm not certain that there is one "actual definition", but Paul posted two of them. Let's look at those. (The third he posted was for something called an "irreducibly complex evolutionary pathway", and it seems to me that the definition defines something that does not exist.)
A single system which is composed of several interacting parts that contribute to the basic function, and where the removal of any one of the parts causes the system to effectively cease functioning". (Behe, Darwin's Black Box)
Is the flagellum a "single system"? Check.
"Composed of several interacting parts" Check.
"that contribute to the basic function" Hmm. "Contribute". What does that mean?
"Removal of any one of the parts causes the system to cease functioning" Hmmm....kind of vague. There are some parts that can be removed, and you would still have a flagellum that worked. Others, on the other hand, would make it stop functioning. It seems to me that the parts that "contribute to the basic function" as opposed to, say, improving the basic function, are the ones that can't be removed.
I'm going with IC on this one, but if you think you've caught Behe in a lie on this basis, be sure to pat yourself on the back.
Let's try Dembski.
Quote:
A system performing a given basic function is irreducibly complex if it includes a set of well-matched, mutually interacting, nonarbitrarily individuated parts such that each part in the set is indispensable to maintaining the system's basic, and therefore original, function. The set of these indispensable parts is known as the irreducible core of the system. (Dembski, No Free Lunch)
Oh, wait. It's the same, but with more adjectives, and it throws in the "and therefore original". I think that phrase is misleading at best, wrong at worst. Other than that, though, it seems that the flagellum performs a basic function with a group of parts, and some of those are indeed indespensable. Thanks, Bill, for clearing up the ambiguity on "contribute to the basic function" by defining the "irreducible core". Seems like the flagellum meets these two definitions.
The definition I made up is basically Dembski's, but with fewer adjectives.
So, which definition doesn't it meet?
Don't answer if you don't want to, but by trying to parse Behe's definition in a way it was clearly not intended in order to call him a liar, you have succeeded at a task many would not have thought possible. You've made Behe look smart.
