Michael Hand just called me to ask a question, and thought I’d post about it. He seems to recall seeing a passing remark in some David Lewis paper against antirealist attempts to substitute some notion of warrant in place of truth in the theory of meaning, but can’t remember where. The remark was a very cursory argument against such attempts, to the effect that any clarification of the meaning of warrant will have to appeal to the concept of truth anyway (perhaps through some connection to likelihood of truth), so the antirealist attempts to replace truth with warrant are bound to fail.
I don’t recall seeing any such argument in Lewis, but others know his work better. Michael also wondered about the argument, whether epistemologists talk much about it, and whether it is thought to be a good argument. I told him what I thought, but I’d rather see what others think before saying here. Any thoughts on either question?
