ABSTRACT
The vast majority of philosophers accept Assertion Incompatibilism: according to this view, given intuitive variability of proper assertion with practical stakes, non-shifty invariantism (NSI) is incompatible with a biconditional knowledge norm of assertion (KNA). There are also a few dissenting voices, however: some invariantists venture to explain the sensitivity data for proper assertion in a fashion that preserves both NSI and KNA (Assertion Compatibilism). In this chapter, I argue that my preferred incarnation of Compatibilism fares better than the competition. According to the competition, shiftiness in proper assertability is to be explained via appealing to the pragmatics of language. According to the view I defend, what varies with practical considerations is the all-things-considered propriety of assertion: epistemic propriety and the epistemic standard at stake are invariant.
