In his "What Is This Thing Called Knowledge?", Duncan Pritchard claims that anti-realists about truth hold that since truth and best possible opinion are indistinguishable, we should only care about the latter. He then attacks the idea that two things which are indistinguishable are always equally valuable. But surely this a straw man! The anti-realist thinks that truth and our best possible opinion are *identical*; that there is no distinction of the kind Pritchard presupposes. #epistemology
I wrote a possibly nice introduction to anti-realism about truth a while ago:
