First of all I would like to restate what I have said in previous posts and in other threads.
I am not saying that ID is incorrect and I am not saying that it shouldn't be taught in theology and philosophy classes.
I'm new here, so I haven't seen those other discussions, but thanks for the clarification, and thanks for presenting argument.
Firstly, ID is a cosmological argument for the existence of a first cause (God). Again, I am not saying that the argument isn't valid. What I am saying is that science doesn't deal in first causes.
I disagree with that characterization of ID. As I see it, ID is an argument TO design, not an argument FROM design. Also, biological ID (as opposed to cosmological) doesn't deal with first causes in the sense that I think you mean. Cosmological ID, aka the Fine-Tuning argument, may be problematic in that respect. I'll have to think about it.
Secondly, ID cannot be proven false. Science theories must always have the potential to be proven incorrect.
It's generally recognized that this condition is too strong, since it would also rule out many other theories that are accepted as scientific. I think it's more reasonable to say that there must be observations that would count against a scientific theory, as well as observations that would count for it. ID satisfies this condition.
A simple thought experiment. Maybe you remember the (ancient) film "2001: A Space Odyssey". In that film, a monolith is discovered on the Moon.
I see no reason why it wouldn't be a legitimate scientific inference to conclude that the monolith was intelligently designed, even in the absence of any knowledge at all about the identity of the designer, purpose, etc. The inference would be based on observation alone.
Thirdly, ID isn't a legitimate hypothesis because all scientific hypotheses must be testable. There is no scientific experiment that can be set up to prove the existence of God.
I agree, but ID can only support an inference to a designer, not to God, so this argument isn't relevant. Simply as an inference to a designer, ID is testable.
Take a sample ID inference:
1. Structure X could not be formed by natural means.
2. If something is not formed by natural means, it is formed by the action of an intelligent agent.
3. Therefore structure X was formed by the action of an intelligent agent.
That argument is logically valid, but it is certainly capable of being tested. Premise 1 is open to testing, and premise 2 is subject to falsification, if someone can come up with an alternative way that things can be formed.
