Pyrrho of Elis (//; Ancient Greek: Πύρρων ὁ Ἠλεῖος, romanized: Pyrrhо̄n ho Ēleios; c. 360 – c. 270 BC), born in Elis, Greece, was a Greek philosopher of Classical antiquity, credited as being the first Greek skeptic philosopher and founder of Pyrrhonism.
Pyrrho of Elis is estimated to have lived from around 365/360 until 275/270 BCE. Pyrrho was from Elis, on the Ionian Sea. He was likely a member of the Klytidiai, a clan of seers in Elis who interpreted the oracles of the Temple of Zeus at Olympia where Pyrrho served as a high priest. The Klytidiai were descendants of Klytios, who was the son of Alcmaeon and the grandson of Amphiaraus. In the Python, Pyrrho's student Timon of Phlius describes first meeting Pyrrho on the grounds of an Amphiareion, i.e., a temple of Amphiaraus, while they were both on a pilgrimage to Delphi.
Most biographical information on Pyrrho, as well as some information concerning his demeanor and behavior, come from Diogenes Laertius; his work on Pyrrho's life drew primarily from the works of mid-third century BC biographer Antigonus of Carystus. Diogenes Laërtius, quoting from Apollodorus of Athens, says that Pyrrho was at first a painter, and that pictures by him were exhibited in the gymnasium at Elis. Later he was diverted to philosophy by the works of Democritus, and according to Diogenes Laërtius became acquainted with the Megarian dialectic through Bryson, pupil of Stilpo. Unlike the founders of other Hellenistic philosophies, Pyrrho was not substantively influenced by Socrates.
Pyrrho, along with Anaxarchus, travelled with Alexander the Great on his Indian campaign, "so that he even went as far as the Gymnosophists in India and the Magi" in Persia. Returning to Elis, he lived in poor circumstances, but was highly honored by the Elians, who made him a high priest, and also by the Athenians, who conferred upon him the rights of citizenship.
Pyrrho's pupils included Timon of Phlius, Hecataeus of Abdera, and Nausiphanes, who was one of Epicurus' teachers. Arcesilaus was also a pupil of Pyrrho, and he maintained Pyrrho's philosophy except in name. Upon becoming scholarch of the Platonic Academy, Arcesilaus transformed its teachings to conform with those of Pyrrho. This initiated Academic Skepticism, the second Hellenistic school of skeptical philosophy.

Pyrrho did not produce any written work. Most of the information on Pyrrho's philosophy comes from his student Timon. Only fragments of what Timon wrote have been preserved, mostly by Sextus Empiricus, Diogenes Laertius, and Eusebius. Little is known for certain about the details of Pyrrho's philosophy and how it may have differed from later Pyrrhonism. Most of what we know today as Pyrrhonism comes through the book Outlines of Pyrrhonism written by Sextus Empiricus over 400 years after Pyrrho's death.
Most sources agree that the primary goal of Pyrrho's philosophy was the achievement of a state of ataraxia, or freedom from mental perturbation, and that he observed that ataraxia could be brought about by eschewing beliefs (dogma) about thoughts and perceptions. However, Pyrrho's own philosophy may have differed significantly in details from later Pyrrhonism. Most interpretations of the information on Pyrrho's philosophy suggest that he claimed that reality is inherently indeterminate, which, in the view of Pyrrhonism described by Sextus Empiricus, would be considered a negative dogmatic belief.
A summary of Pyrrho's philosophy was preserved by Eusebius, quoting Aristocles, quoting Timon, in what is known as the "Aristocles passage." There are conflicting interpretations of the ideas presented in this passage, each of which leads to a different conclusion as to what Pyrrho meant:
'The things themselves are equally indifferent, and unstable, and indeterminate, and therefore neither our senses nor our opinions are either true or false. For this reason then we must not trust them, but be without opinions, and without bias, and without wavering, saying of every single thing that it no more is than is not, or both is and is not, or neither is nor is not.
It is uncertain whether Pyrrhonism was a small but continuous movement in antiquity or whether it died out and was revived. Regardless, several centuries after Pyrrho lived, Aenesidemus led a revival of the philosophy. Pyrrhonism was one of the two major schools of philosophical skepticism that emerged during the Hellenistic period, the other being Academic skepticism. Pyrrhonism flourished among members of the Empiric school of medicine, where it was seen as the philosophic foundation to their approach to medicine, which was opposed to the approach of the Dogmatic school of medicine. Pyrrhonism fell into obscurity in the post-Hellenistic period.
Pyrrhonists view their philosophy as a way of life, and view Pyrrho as a model for this way of life. Their main goal is to attain ataraxia through achieving a state of epoché (i.e., suspension of judgment) about beliefs. One method Pyrrhonists use to suspend judgment is to gather arguments on both sides of the disputed issue, continuing to gather arguments such that the arguments have the property of isostheneia (equal strength). This leads the Pyrrhonist to the conclusion that there is an unresolvable disagreement on the topic, and so the appropriate reaction is to suspend judgement. Eventually the Pyrrhonist develops epoché as a habitual response to all matters of dispute, which results in ataraxia.
Diogenes Laërtius' biography of Pyrrho reports that Pyrrho traveled with Alexander the Great's army on its conquest of India (327 to 325 BCE) and based his philosophy on what he learned there:
...he even went as far as the Gymnosophists, in India, and the Magi. Owing to which circumstance, he seems to have taken a noble line in philosophy, introducing the doctrine of incomprehensibility, and of the necessity of suspending one's judgment....
The sources and the extent of the Indian influences on Pyrrho's philosophy, however, are disputed. Philosophical skepticism was already present in Greek philosophy, particularly in the Democritean tradition in which Pyrrho had studied prior to visiting India. Richard Bett heavily discounts any substantive Indian influences on Pyrrho, arguing that on the basis of testimony of Onesicritus regarding how difficult it was to converse with the gymnosophists, as it required three translators, none of whom understood any philosophy, that it is highly improbable that Pyrrho could have been substantively influenced by any of the Indian philosophers. It has also been hypothesized that the gymnosophists were Jains, or Ajnanins, and that these are likely influences on Pyrrho. Authors see probable influence of Indian skepticism not only in Pyrrhonism, but also in Buddhism itself as a common ground.
