 Epistemic paradoxes are riddles that turn on the concept of knowledge (episteme is Greek for knowledge). Typically, there are conflicting, well-credentialed answers to these questions (or pseudo-questions). Thus the riddle immediately poses an inconsistency. In the long run, the riddle goads and guides us into correcting at least one deep error – if not directly about knowledge, then about its kindred concepts such as justification, rational belief, and evidence.
