And if truth is relative, then there is no single shared definite aim for any given assertion (see MacFarlane 2014: ch. 12 for a discussion). The relativists however, could respond that truth is relative to a group (conceptual scheme, framework) and they take speakers to be aiming a truth relative to the scheme that they and their interlocutors are presumed to share. The difficulty with this approach is that it seems to make communication across frameworks impossible.
