Well, OK, but then it seems Peirce's conception of truth is just as potentially unattainable (and thus philosophically useless, by his own account) as the correspondence conception. Unless I've reached an ideal limit of inquiry -- which of course I can't really know I've done, and am unlikely to have done -- then it seems I don't actually have truth, even on Pierce's account.

That aside, though, point taken about epistemicism != Peirce; presumably if I actually care about the latter I should just read Peirce. I'm just being intrigued by it. I do think I roughly understand the concept now; thanks for the explanation.
