Pyrrho of Elis

Founder of Skepticism — suspend judgement to find peace.

Skepticism (Pyrrhonism)HellenisticAncient Greek360–270 BCE◦ Elis4th century BCE

Overview

Pyrrho, who reportedly traveled to India with Alexander's army and met 'naked sages', founded Greek skepticism. He taught that we cannot know the true nature of things, since for every argument there is an equal and opposite one. The wise response is epochē — suspension of judgement — which brings ataraxia, tranquillity. Like Socrates and Diogenes he wrote nothing; his outlook survives through his pupil Timon and, centuries later, the systematizer Sextus Empiricus.

What they supported — and why

Things are indeterminable

SupportedWe cannot know how things really are in themselves — appearances conflict and no criterion settles them.

WhyFor any claim, equally strong opposing claims can be made, so no judgement is more justified than its contrary.

Suspend judgement (epochē)

SupportedWithhold assent on all matters of how things really are; go by appearances for practical life.

WhySince we cannot decide, refusing to commit frees us from the errors and anxieties of dogmatic belief.

Tranquillity follows

SupportedSuspending judgement yields ataraxia — untroubled calm.

WhyMuch distress comes from believing things are good or bad by nature; dropping such beliefs quiets the mind.
