  The prospects of such a response depend on what the accessibility is taken to entail. There may be little reason for realists to go beyond the relatively modest claim that we can attain knowledge of some moral facts in favorable circumstances. Given such a weak interpretation of “accessible”, realists may employ all the strategies outlined in section 1.3 to argue that most of the existing disagreement occurs between persons who are not in ideal circumstances which would render it irrelevant in the present context. After all, the fact that people have failed to reach agreement (which entails, on a realist view, that some have failed to obtain knowledge) in conditions that are not favorable need not show that they would fail also in circumstances that are. As for the remaining disagreement, such as that between philosophers, realists could point out that it primarily concerns highly general and theoretical facts whose accessibility they can consistently remain agnostic about, for example due to underdetermination concerns.
