Sextus' life and works

The two books Against the Logicians are part of a larger work by Sextus Empiricus, the best known ancient Greek skeptic and the only one from whom we possess complete texts, as opposed to fragments or second-hand summaries. About Sextus Empiricus himself we know virtually nothing. He identifies himself as a member of the Pyrrhonist skeptical tradition, on which more in the next section. He occasionally refers to himself in the first person as a medical practitioner (PH 2.238, M 1.260, cf. M 11.47). His title would suggest that he was a member of the Empiricist school of medicine. This is confirmed by Diogenes Laertius (9.116), who refers to him as “Sextus the Empiricist”; it would anyway not be surprising, given that we know the names of several other Pyrrhonists who were also Empiricists. Sextus at one point addresses the question whether medical Empiricism is the same as Pyrrhonist skepticism (PH 1.236–241), and unexpectedly replies that another school, the Methodist school, has closer affinities with skepticism. However, it is possible to read this passage as expressing suspicion towards a certain specific form of Empiricism, rather than towards the school as a whole.

Such indications as there are concerning where Sextus was born, or where he worked in his maturity, are too slender to bear any significant weight. The evidence suggests that he lived in the second century ce, but it is not clear that we can fix his dates with any more precision than that.
