Pyrrho

Also known as Pyrrho of Elis

HellenisticSkeptic

Born c. 365 BCE

Died c. 275 BCE

Suspend judgment. The world as we think we know it may not be the world at all.

Pyrrho traveled with Alexander’s army to India, where he encountered thinkers who profoundly unsettled his certainties. He returned to Greece and taught that we cannot know the true nature of things. The proper response to this is not despair but tranquility: if you stop clinging to opinions, you stop suffering. His radical skepticism influenced every later tradition that asked how much we can really know.

A lone traveler stands where several stone paths split through misty cliffs, with pale moons and uncertain lights suspended in the fog. — Peace begins where certainty divides.

Influence

Influenced by

Socratesindirect influence

The Buddhapossible influence via Alexander's campaigns

Influenced

Sextus Empiricusskeptic tradition
Sextus systematized and preserved the Pyrrhonist skepticism that traced back to Pyrrho.
Carneadestwo rival skepticisms
Pyrrho's radical suspension of judgment and Carneades' Academic skepticism represent the two great branches of ancient doubt; Carneades' theory of degrees of plausibility was in part an attempt to answer critics who found Pyrrhonism's total suspension impossible to actually live by.
