Anti-individualism, content preservation, and discursive justification

Most explorations of the epistemic implications of Semantic Anti-Individualism (SAI) focus on issues of self-knowledge (first-person authority) and/or external-world skepticism. Less explored has been SAIs implications for the epistemology of reasoning. In this paper I argue that SAI has some nontrivial implications on this score. I bring these out by reflecting on a problem first raised by Boghossian (1992). Whereas Boghossian's main interest was in establishing the incompatibility of SAI and "the a priority of logical abilities" (Boghossian 1992: 22), I argue that Boghossian's argument is better interpreted as pointing to SAI's implications for the nature of discursive justification.
