 These two positions under the broad description of metaepistemological relativism—the explicitly relational kind of relativism Boghossian attributes to Rorty, and the semantically motivated “new age” relativism about knowledge attributions defended by MacFarlane—are strikingly different. Each appeals to distinctive kinds of considerations and is subject to distinctive kinds of criticisms. The former appeals, e.g., to considerations of tolerance and diversity (e.g., Rorty 1979, 1989). The latter appeals to patterns of our use of “knows” in the service of defending truth conditions for knowledge ascriptions; as such it is a semantic thesis. A point we will take up in  §3.2  is the broader epistemological question of how to locate semantic theses about “knows” within epistemological theorizing.
