Annafan, this is actually a reply to
post 35 in "ID taken to the end". I understood your questions / points about this thread there better than here, so I'm responding to that post but pulling the discussion back over here.
I still fail to see where the ID hypothesis leads to. Really, I guess I just don't understand how proposing an "intelligent designer" can be considered a satisfying answer.
I look at it this way. IF we accept that evolution could not have produce, or simply did not produce, a structure that we observe (and I KNOW this is a huge IF, but let's see where it leads to), THEN we have to change the way we think about the origins of what we see today.
ID is one way to do that. It allows for structures that are "designed." As I showed previously in the other thread, it also can allow for mutation, for natural selection, and evolution.
It's the type of answer that fits everything.
ONLY if you make your designer some kind of God. As we've seen over and over, "God" cannot be scientific; "God" can do anything, anytime, any way. So, assume a non-God designer. IF we accept that some structures are not explained by evolution, can we determine if they are designed and, if so, can we determine anything about the designer?
How many of those [ID] claims have to be eliminated before it becomes clear that "ID" is just a silly placeholder for the "as yet unexplained"?
But that's what I've been trying to explain. Scientific theory often follows this path: first explain something descriptively and, if you can do that successfully, THEN derive further evidence which can tell you what's in the black box. That worked for evolution, that worked for Newton's theory of gravity... it's not out of the question it could work for ID.
It is no use to invoke something like an intelligent extraterrestrial species as our "engineers", because even if that were true you would have to come up with an explanation for THEIR origins.
Now this is a completely different problem. I think we're in the business of understanding how biology on the Earth works; if we discovered we were engineered by extraterrestrials, taht would be a HUGE breakthrough in understanding, and it would fundamentally alter how we view the history of the earth and the history of how evolution has worked in our world.
You're right though; we would still have other questions relating to orgins. But as we've said, evolution is NOT a question of "ultimate" origins; abiogenesis is. If we discovered we were engineered by aliens, that would be a HUGE step in another direction for chemists. They would no longer study old earth chemistry, but would need to figure out the origin (location) of the extraterrestrials, they'd have to see if they could reduce life to basic origins through a theory like evolution, and then they'd need to study the ancient chemical makeup of that origin (location). That would be HUGE, HUGE. Not irrelevant at all.
It would absolutely make no sense to try to figure out the contents of the other box on its own, because it is tied to the "intelligence" black box. A seperate interpretation of the other black box would always be distorted or disjointed. Maybe it's even impossible to just peek inside, if you haven't first figured out the "intelligence" box.
You've basically just described how we study cognition. We're constantly having this problem. We have one big black box (the human mind). We propose some smaller black boxes to fill the big black box. We try to make them consistent with each other. Then, we tackle the smaller black boxes. If we discover we thought about one of the black boxes incorrectly, since all the boxes are dependent on each other, we often have to start from scratch.
This is a bit of a simplification, but the basic point remains: in this point, I don't see that ID is any worse off or invalid than other approaches we accept.
By the way, at this point I'm not talking about ID as the existing theories; like we've discussed, they don't even qualify. I'm talking about ID in general. In general, if we can support the major premise (that there are structures that are not explained by evolution), it's not a worthless enterprise.
