Pyrrhonian Sceptic

Sextus Empiricus

Σέξτος Ἐμπειρικός

fl. c. 200 CE · Uncertain; a physician of the Empiric school

A doctor and Pyrrhonian Sceptic whose Outlines of Pyrrhonism is our fullest ancient account of scepticism. Little is known of his life. He presents scepticism not as a theory but as an ability and a way of living: setting arguments against each other and suspending judgment.

Key ideas

  • For every argument an equal opposing argument can be set
  • Suspension of judgment (epochē)
  • Tranquillity (ataraxia) reported to follow suspension, not sought through a doctrine
  • Living by appearances, nature, custom and skills without dogmatic belief

Passages

Paraphrase

The sceptic’s aim, Sextus says, is tranquillity in matters of opinion and moderate feeling in what cannot be avoided, such as hunger or cold, since he does not add the belief that these are bad by nature.

Paraphrase

Scepticism, Sextus says, is an ability to set appearances and thoughts against one another, so that through the equal force of opposing accounts we come first to suspension of judgment and then to tranquillity.

Paraphrase

The painter Apelles, unable to paint a horse’s foam, flung his sponge at the picture in frustration, and it left the very mark of foam. So, Sextus says, sceptics found tranquillity following suspension of judgment as if by chance.

Paraphrase

Sceptics live without dogmatic beliefs by following appearances: the guidance of nature, the compulsion of feelings, the laws and customs they grew up with, and the teaching of skills.

Paraphrase

Sextus collects examples of how customs and laws differ between peoples, so that what is shameful in one place is acceptable in another; we can say how things appear to each, not how they are by nature.

Paraphrase

Paraphrase

Sceptical phrases such as “no more this than that” apply to themselves too, Sextus says, like purgative drugs that flush themselves out along with what they expel.

The sceptic, Sextus notes, does not claim that nothing can be known; he keeps searching, unlike those who say they have found the truth or that it cannot be found.
