INTRODUCTION

English translation pending.

CORE DEFINITION

Epistemic paradoxes are puzzles built around the concept of knowledge, episteme in Greek: for the same question there are conflicting yet individually well-supported answers, and the puzzle immediately produces inconsistency, forcing revision of at least one deep assumption. Classic cases include the lottery paradox, the preface paradox, and the knowability paradox, each turning on principles connecting knowledge with truth, belief, and justification.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Stress-test intuitions: run several individually plausible principles about knowledge together and see where they collide. - Locate the faulty premise: work backward from the contradiction to identify the harmless-looking principle that must go. - Check spillover: see whether the repair disturbs neighboring notions such as justification or rational belief.

Anchor fast decisions

The concept of knowledge is usually tied to principles about truth, belief, justification, and closure. When those principles collide in situations involving self-reference, statistical evidence, or expert authority, a contradiction follows from seemingly innocent premises, so one of the intuitions must be abandoned.
