No. Your right. I can't. I can't because you won't decide between two incommensurable criteria (abstract thought being involved on one hand, versus reference to past unobserved phenomena on the other). Not that it matters because neither criteria works anyway. They both include far too many things that no one considers "metaphysical".
I've already criticized both criteria anyway; and you haven't responded to my criticisms.
I have decided and presented. You merely confused yourself.
Just because 'no one' considers them metaphysical doesn't mean they aren't. That's the whole problem. Evos don't recognize the metaphysical nature of evolution. They think it really is 'scientific' because you all agree that it is.
Your criticisms were founded in confusion. I can't help you w/ your confusion. Just because you criticize doesn't mean it's invalid.
You have failed to counter claims that evolution is metaphysical. You just won't admit it.
