Era: Hellenistic (c. 300 BCE) – Sextus Empiricus (2nd c. CE) Key figures: Pyrrho of Elis · Aenesidemus · Sextus Empiricus
For every argument there seems to be an equal and opposite one — so the skeptic suspends judgement (epochē) on how things really are, lives by appearances and local custom, and finds that tranquillity (ataraxia) follows the suspension like a shadow. Its many `uncommitted` positions below are the point, not a gap.
Signature commitments
For any claim, set opposing arguments of equal strength against each other (isostheneia) and the result is suspension of judgement.
Suspend judgement (epochē) about how things really are, while still living by how they appear.
Tranquillity (ataraxia) is not chased directly; it follows suspension 'as a shadow follows a body.'
Where it stands on the axes
The nature of reality
Takes no fixed position. Suspends judgement on all claims about what is ultimately real.
How we knowcontested
Takes no fixed position. The core stance: no criterion of truth is secure, so judgement is suspended — while the skeptic still acts by how things appear (phainomena), undogmatically.
What makes an action right
Takes no fixed position. Suspends judgement on what is good or bad by nature; follows local law and custom without endorsing it as true.
Where meaning comes from
Takes no fixed position. Makes no claim about meaning; tranquillity comes from suspending judgement, not from any meaning found.
What people are like underneath
Takes no fixed position. Advances no doctrine of human nature.
Free will
Takes no fixed position. Treats the free-will/determinism dispute as one more dogmatic quarrel to suspend judgement on.
The individual and the group
Takes no fixed position. No social doctrine; the skeptic conforms to local practice as a practical, non-committal way to live.
How power should be arranged
Takes no fixed position. Takes no stand on how authority should be arranged.
How change should happencontested
Preservation. In practice, living 'in accordance with everyday observances' means following existing laws and customs — de facto conservatism, not a principled defence of the order.
Marked readings are ones serious scholars dispute; the note says how. Traditions are living arguments, not fixed doctrines.
Common misreadings
That the skeptic claims 'nothing can be known' — that would itself be a dogmatic claim; the Pyrrhonist suspends judgement even about whether knowledge is possible.
That skepticism means paralysis — Sextus insists the skeptic acts normally, guided by appearances, instinct, custom, and craft, just without asserting they're true.
Where a reader might diverge
If you hold even one confident claim about how reality really is, you've stepped outside Pyrrhonian suspension.
If you think reason can settle at least some deep questions decisively, you side with the 'dogmatists' the skeptic opposes.
A challenge to it
The critic of self-refutation: Suspending judgement about everything looks unlivable and self-undermining: to recommend skepticism as leading to tranquillity is itself to assert something — the skeptic seems to smuggle in the very kind of claim they forswear.
In their own words
Tranquillity follows the suspension of judgement as its shadow follows a body.

Inner Axis never pins a school on you. A reading describes where your answers resemble a tradition and where they part from it — a family resemblance, not a label you carry.
