Aenesidemus

Aenesidemus ( or Αἰνεσίδημος) was a 1st-century BC Greek Pyrrhonist philosopher from Knossos who revived the doctrines of Pyrrho and introduced ten skeptical "modes" (tropai) for the suspension of judgment. He broke with the Academic Skepticism that was predominant in his time, synthesizing the teachings of Heraclitus and Timon of Phlius with philosophical skepticism. Although his primary work, the Pyrrhonian Discourses, has been lost, an outline of the work survives from the later Byzantine Empire, and the description of the modes has been preserved by a few ancient sources.

== Life == There is no definitive evidence about the life of Aenesidemus. What little we know is from a description of his Pyrrhonian Discourses in the Myriobiblion of Photius from the 9th century, as well as a few mentions in the works of Sextus Empiricus, and to a lesser extent by Diogenes Laërtius.
