I was reminded in looking at Frank's site of how pathetic he really is, which led to me remembering when I actually used to waste time arguing with people like him, the Triabloguers and other presuppositionalists. They waste such time by doing something simple: conflating strict reductionist physicalism/materialism with atheism.
When one begins with the fundamental presupposition that God has spoken in the Scriptures in Christ’s Law-word, you are left with the only worldview that can consistently allow for immaterial, universal, and abstract things like laws of science, laws of logic, and abstract concepts.Funny, I thought there were numerous metaphysical ways to describe universals, properties and relations besides "Jesus"...
As has been pointed out before, the absurd burden of proof which these guys place on themselves requires them to show how every other explanation in metaphysics is logically inconsistent. Quite a tall order, given that brilliant philosophers have spent centuries thinking about these things. Instead, they use a simple straw man wherein atheists must be strict materialists who cannot embrace nominalism or conceptualism or any other theory of universals.
In addition, they hold that internal critiques are all that can be done "across worldviews" because of different presuppositions, but then proceed to contradict that by saying that certain basic beliefs are not justified within other worldviews (i.e., that logic is self-evident and incorrigible, that morality is about causing harm, &c.)
