I frequently argue the virtues of anti-epistemological pragmatism(neopragmatism) with people who hold more traditional epistemological views. The most common argument that I hear is:
Well, if we take a 'true fact' to be a useful fact, then doesn't that force us to define some absolute ground for truth, usefulness, which in turn requires an epistemic grounding?
I'll admit, I have a tough time dealing with this criticism. My usual response is to argue that:
A sufficient explanation of why the idea that we need this sort eternal epistemic truth is flawed.
That the idea that this kind of truth needs an epistemic ground is an assumption baked into the modernist epistemological framework that began with Descartes(PMN).
And that the usual prephilosopher doesn't seem to have any particular desire for a highly rational epistemic framework that will ground all truth forever(Dewey).
This is barely an argument. I'm wondering how other pragmatists would respond to this kind of critique.
