Abstract: Hinge propositions, or simply “hinges”, are primitive certainties that we (must) presuppose in our normal inquiries. Recently there has been a lot of interest in hinge epistemology, which is a kind of epistemology that sets the notion of hinge at the center stage. This paper puts forward a dilemma leveled against hinge epistemologists. The dilemma is based on work by Pascal Engel (2016) and it states that, given the assumption that hinge propositions are normative at all, they are either grammatical or epistemic norms. If the former is the case, then hinges would appear to be irrelevant to epistemology as it is ordinarily conceived, while if the latter holds, hinges would have to compete with other types of epistemic norms, resulting in an incomprehensible epistemology altogether. After presenting Engel’s dilemma, it is utilized to tease out certain bleak insights about logical disagreement.
