Yablo's Paradox
Updated 2026-08-01
INTRODUCTION
English translation pending.
CORE DEFINITION
Presented by philosopher Stephen Yablo. The sequence consists of infinitely many sentences, each of which says that every sentence after it is false. Reasoning through the sequence produces a contradiction, yet no sentence refers to itself, only to later ones. The construction challenges the view that semantic paradox requires self-reference and supports accounts locating the problem in circularity or in the absence of a grounding anchor.
SCAFFOLDING EFFECT
Reduce cognitive load
- Check the structure: distinguish a genuine self-referential loop from an ungrounded chain of claims - Find the anchor: ask what independent fact any claim in the chain rests on - Break the chain: introduce a shared factual baseline instead of adding another accusation
Anchor fast decisions
Each sentence's truth depends on the falsity of every later one, and the sequence never terminates, so no sentence has an independent basis. Evaluation can never bottom out, and any assignment of truth values propagates a contradiction along the whole chain. The paradox therefore arises from the absence of grounding rather than from any sentence referring to itself.
