As to your OP -
But seriously, all branches of epistemology have underlying assumptions / axioms - assumptions that one who favors another branch to tackle an epistemological is not likely to share. To an empiricist (at least to me), presupposition sounds like bullshit, and the reverse is likely true as well. I cannot reasonably assert that they are wrong - though I remain unconvinced that presuppositionalism is anything but circular wishful thinking. I *can* point to empiricism's track record and explain how it has been *useful* - but that comes down to a question of what one values.
I'm tentatively convinced that it's all a matter of what approach one prefers more than anything, and that claims of "truth", particularly capital-T Truth are not entirely justified.
On a more important note. Is your new avatar picture of anyone we should know? Did you get a new familiar? (Good looking pup!)
I don't think presuppositionalism can really do any positive, constructive work for you. It is more a humbling recognition that we aren't any of us in any position claim capital T truth, once and for all. If someone making extraordinary claims wishes to squirt out an inkjet of presuppositionalism as they slither into the depths - fine with me. But to think it makes you king of the hill is a step too far.
