I read over my response, and I should clarify something:

***C1 - ‘Hence, reality is metaphysical.’

"I can accept if by 'metaphysical' you mean that the phenomena in question is beyond our ability to reduce to a satisfactory scientific explanation, then by the implications of P1' I would have to agree with this conclusion (your logic is not complete to make this conclusion, however I think the conclusion can be substantiated)."***

This should say:

C1 - 'Hence, [ultimate] reality is metaphysical.'

What I mean to say here is that ultimate reality is metaphysical (i.e., it cannot be reduced to a satisfactory scientific explanation because such an explanation is self-contradictory). I didn't provide my version of logic to support this contention, but if you're interested I'll provide that.
