Lately I have been feeling irrational/fideistic/existential.
just kidding. I like a lot of what Van Til had to say. Read most everything he wrote, bahnsen wrote, and frame wrote. I disagree with Van Til's critiques of other apologists, though. In fact, I can show where Van Til uses the same terminology and methods as people he critiques (actually, followers of people he critiques use the same stuff as Van Til).
I don't hold to the silver bullet TAG (not many do, come to think of it).
As pertaining to a negative critique of opposing worldviews, I am definitely Van Tillian. This was Bahnsen's best arena.
I really don't know what I would at this point as to offering a positive alternative. I guess that's where the existential fideist in me arises, sort of.
Right now, if I had to offer an argument I would just say--look at this example of Beauty. Therefore, God exists (or something like that).
