As I understand it he's saying that conscious exists; science cannot, and never will, explain conscious; because of this, the existence of consciousness proves the existence of god.
he is trying to be more technical. He is saying that science cannot ever explain 'the hard problem of consciousness'. It doesn't really affect the argument though. It is a god of the gaps argument. If you read his writing on the subject, the vast majority of it is talking about how science doesn't/can't explain it. He doesn't actually show that god explains it, or anything else.
I have told him that it is obviously a god of the gaps argument. His response is that it is not, because not only can science currently not explain it. Science never will be able to explain it. He is under the impression that if you are pointing to a gap in knowledge and at the same time insisting that the gap is permanent, it is no longer a god of the gaps argument.
If I'm right that seems like a dangerous argument, since he's given us a way to categorically disprove the existence of god: Find a scientific explanation for consciousness.
I wouldn't call it a 'dangerous' argument. finding the explanation for the 'hard problem' would simply debunk that argument. It wouldn't debunk god. But the argument is already debunked anyway because like every other argument from every other apologist from every other religion, it just does't work. It's simply not true that if we dont know how something works (now or ever), then god did it.
i've not come across any other Muslims using it yet. Maybe they aren't too impressed either
