I'm not operating out of any "worldview" because the concept as used by presuppositionalists is meaningless. I don't have any "presuppositions" because the concept as used by presuppositionalists is meaningless. Neither of these points are relevant to this discussion - they are merely diversionary tactics used by presuppositionalists to divert attention from the failure of their arguments.
No presuppositions, eh? None? No fundamental axiom? This is simply ridiculous.
How do you prove that evidence is evidential?
That you are not a brain in a vat?
That evidence is a good way to discover truth?
How do you know that you know anything?
That your cognitive faculties are properly aimed at forming true beliefs?
How do you prove that the laws of logic are useful?
Anwer any of these without appealing to a fundamental axiomatic statement, and you will be begging the question. Such as:
"I know that evidence is a good way to discover truth because I use it every day to live my life."
You're begging the question - I simply ask how you know:
1) that you use it every day
2) that you are living your life
3) that it's good rather than bad for that purpose
4) that you actually arrived at truth.
And on and on.
How warm a welcome would Paul give to a statement like "God just is. That's it"? He'd call it circular. Indeed, and the same goes for his statements. The difference is that appealing to "God just is" is not viciously circular because the God of the Bible is self-justifying; He is where the buck stops. On Paul C's worldview (which he claims he doesn't have), the buck never stops, and that's a problem.
Here is a related post, and my long interaction with the Jolly Nihilist is instructive too. At any rate, Paul talks big and is obviously a sharp fellow, but sometimes he says amazingly poorly-thought-out things.
