I do want to establish that I invented the swamping problem, and I really am just returning to the discourse in epistemology, so I've had to try to catch up. Meanwhile yet another revision of the charge sheet on Zagzebski; I will get this exactly right eventually. (Replaced in timeline as well.)
Duncan Pritchard, in a draft paper titled What is the Swamping Problem?, gives the following pedigree.
This difficulty is the so-called ‘swamping problem’, as defended most prominently by Jonathan Kvanvig (e.g., 2003), but also put forward in various forms by Ward Jones (1997), Richard Swinburne (1999; 2000), Wayne Riggs (2002), Linda Zagzebski (2003) and John Greco (forthcominga).
I am going to try to go at these in order, one at a time. Ward Jones' paper (American Philosophical Quarterly, October 1997), early on sets up the question with a quotation from me (page 424), and section 2 is a remarkably close recapitulation of section 3 of my journal of philosophy paper.
He formulates the problem in just my terms, attacks reliabilism with it as I did, then actually brings the same quotations to bear as I did, and Zagzebski.
Jones p. 427:
I have been discussing the reliabilist in particular, but I should reemphasize that I consider the relibilist to be representative of epistemic instrumentalists. Laurence Bonjour, a coherentist, writes:
If epistemic justification were not conducive to truth in this way, if finding epistemically justified beliefs did not substantially increase the likelihood of finding true ones, then epistemic justification would be irrelevant to our main cognitive goal and of dubious worth. . . . Epistemic justification is therefore in the final analysis only an instrumental value, not an intrinsic one.
And Paul Moser, a foundationalist, writes:
Epistemic justification is essentially related to the so-called cognitive goal of truth, insofar as an individual belief is epistemically justified only if it is appropriately directed toward the goal of truth.
And me, p. 172-73:
Indeed, proponents of all the major conceptions of justification hold this position. For example, the foundationalist Paul Moser writes:
Epistemic justification is essentially related to the so-called cognitive goal of truth, insofar as an individual belief is epistemically justified only if it is appropriately related toward the goal of truth. More specifically, on the present conception, one is epistemically justified in believing a proposition only if one has good reason to believe it is true.
The reliabilist Alvin Goldman claims, similarly, that a condition on an account of justification is that beliefs justified on the account be likely to be true; he says that a plausible conception of justification will be “truth-linked” ( op. cit. 116-21) . And the coherentist Luaurence Bonjour puts it even more strongly. p. 173
If epistemic justification were not conducive to truth in this way, if finding epistemically justified beliefs did not substantially increase the likelihood of finding true ones, then epistemic justification would be irrelevant to our main cognitive goal and of dubious worth. It is only if we have some reason for thinking that epistemic justification constitutes a path to truth that we as cognitive beings have any motive for preferring epistemically justified beliefs to epistemically unjustified ones. Epistemic justification is therefore in the final analysis only an instrumental value, not an intrinsic one.
The quotes are obvious, but the whole discussion is a very close recapitulation of me. And of course, both these discussions are also identical to Zagzebski's. I will say that Jones also did a cut and paste from my paper, but at least he quoted me in proximity, and he comes closer to crediting me with the argument. But we will see that by every route that this argument entered the discourse, it derived from me.
