Abstract

I raise a dilemma for an epistemology based on the idea that there are hinge propositions or primitive certainties: either such propositions are norms or rules in the 'grammatical' sense, but they cannot regulate our inquiries since they are not genuine propositions obeying truth or evidential standards, or they are epistemic norms, but compete with the classical norms of belief and knowledge. Either there are hinges, but they have nothing to do with epistemology, or hinges are part of our knowledge, and their epistemology is part of ordinary epistemology.
