Michael Behe’s Intelligent Design is founded on the belief that there are “irreducible complexities” which would suggest an Intelligent Designer/Creator, which would be a persuasive argument if it was true.
I have a bit of a problem with that statement. To explain why let's look specifically at irreducible complexity and intelligent design and the claims they make. Now, bear with me until the end of this, where you will see that I am not saying what it sounds like I am saying.
Irreducible complexity makes a single claim, that some features found in organisms cannot be the product of evolution because there are no steps between nothing and the fully formed component. You either have that component fully formed or you have something completely useless. If this were true it would be a compelling argument against evolution. Taken by itself irreducible complexity does not point to an alternate method by which the component could come to be, it only suggests that the currently accepted method cannot explain it.
To get to the explanation we go to intelligent design with irreducible complexity as a supporting theory. The single claim intelligent design makes is that life was designed by some intelligence. Although they never actually say it because it would expose the creationist roots of intelligent design very plainly, this intelligence would then have to create the things which it designed. There are many glaring problems with this claim.
First, it is invoking a supernatural explanation, which is forbidden in scientific method. You can offer only natural explanations and creationism is a supernatural explanation.
Second, what evidence is there for this designer/creator? Why decide that it must have been an intelligence? How are you ruling out all unknown possibilities to come to the conclusion that there must have been a designer/creator? What evidence is there for this designer/creator? Because we’ve already established the irreducible complexity is evidence against evolution, not evidence for anything. There is no evidence which would force us to jump to this conclusion. In science it would remain an “unknown” until we had direct observation and facts which pointed to a designer/creator and none has been offered. All that has been offered was, “Evolution is wrong, so this, being all that is left, must be right”. Science doesn’t work this way. You don’t “infer” what is by proving what is not.
Third, it is untestable. There is no test you can perform to give evidence to support the existence of a supernatural designer/creator.
Fourth, it makes no predictions. Based on this, what predictions can you make? That you would find other examples of irreducible complexity in nature? That’s not really a prediction, more of a statement of the obvious. It does, after all, have to be repeatable to be science. If you only ever found one example of irreducible complexity then it would be a fluke. I can think of no real predictions you can make with this.
Fifth, it’s useless. So there’s a designer/creator out there. And? I can’t do anything with that. It won’t help me to live longer or grow better crops. It won’t help me to unravel the mysteries of the universe or figure out why light always travels at the same speed. The conclusion is utterly scientifically useless. There is absolutely nowhere to go from there (which is exactly why a supernatural explanation is forbidden).
ID wouldn’t even make it past premise, much less to hypothesis or theory.
Now, given what you’ve posted even recently it is plainly obvious that you already knew all of that. I am not trying to educate you, just explain the source of my objection to that statement. I can’t see the “persuasive argument” in any of that. Irreducible complexity is an argument against evolution. If true, of course that argument would be persuasive because there would be some evidence to back it up. So that seems like it didn’t need stating. But when it comes to intelligent design, even if it were absolutely true there is no persuasive argument to be had until you can bring me a designer/creator (by the way, I love that you used that too. They use the word “designer” to hide the fact that they are talking about a “creator” and I always love to see when someone is seeing through that). Or at least some evidence to suggest there is one other than what you “infer” because you are unable to think of any other process by which something could come to be. “I don’t know” is a legitimate answer in science, and always more legitimate than, “I can’t think of anything else, so this must be the answer.”
If I misread what you are saying please feel free to correct me. There is every possibility in that. But I don’t see any persuasive arguments in ID at all. As far as I see it’s nothing more than the standard “right by default” mindset held by pretty much all followers of any woo where if they can just prove that all other explanations don’t hold up then theirs, being the only one left, is the “right” answer. You see that in every form of woo. Pushers of alternative medicine try to discredit the pharmaceutical industry. Pushers of alien visitation try to show what a UFO could not be. Pushers of a particular religion try to show that all other religions are wrong. Pushers of crop circles try to show lack of evidence of human involvement. And intelligent design tries to show that evolution is wrong. They think that if they can just eliminate the competition then, being the only one left claiming to have answers will mean that their answer is “right”. That’s not how science and reality work, it’s how woo and bullshit work.
