Pyrrhonian School of Ancient Greek Philosophy Texts

Pyrrhonism

Founding Pyrrho of Elis founded this school in the 4th century BCE. He developed his skeptical outlook after traveling to India with Alexander the Great, where he encountered Indian ascetics. This experience influenced his emphasis on suspending judgment.

Core teachings Pyrrhonism holds that certain knowledge about non-evident matters is unattainable. The skeptic responds to conflicting arguments of equal strength by suspending judgment, a practice called ἐποχή (epochē). The goal of this suspension is ἀταραξία (ataraxia), a state of mental tranquility free from the disturbance caused by holding unprovable opinions.

Pyrrhonists follow appearances. They avoid a cliff not because they dogmatically believe it is dangerous, but because it appears dangerous. They live according to customs, perceptions, and needs without making claims about the underlying nature of things. Pyrrho’s formula captures this: things are “no more” one way than another.

This approach differs from Academic skepticism. The Academics often made the dogmatic claim that knowledge is impossible. The Pyrrhonist suspends judgment even on that question, refusing to affirm or deny the possibility of knowledge itself.

Key figures Pyrrho of Elis (c. 370–c. 272 BCE) was the founder. Timon of Phlius (c. 320–230 BCE) was Pyrrho’s disciple. He recorded and disseminated the teachings through prose and verse. Aenesidemus (1st century BCE) revived the tradition in the Hellenistic period, formally distinguishing it from Academic skepticism. Sextus Empiricus (c. 2nd–3rd century CE) was a physician who systematized Pyrrhonian arguments. His works, like Outlines of Pyrrhonism, are the primary sources for the school’s doctrines.

Historical development After Pyrrho’s death, Timon spread his ideas. The school then faded until Aenesidemus revived it centuries later. This revival explicitly positioned Pyrrhonism against the dogmatic tendencies of the contemporary Academy. The tradition was most fully articulated in the Roman period by Sextus Empiricus, whose writings preserved its arguments for posterity.
