Xeniades (Greek: Ξενιάδης) was a skeptical philosopher from Corinth, probably a follower of the pre-Socratic Xenophanes.
Xeniades was supposed to have been the man who persuaded Monimus to become a follower of Diogenes, and was the source of his skeptical doctrines.
[1] The little that is known of him is derived from Sextus Empiricus, who represents him as holding the most ultrasceptical opinions, and maintaining that all notions are false, and that there is absolutely nothing true in the universe.
[6] Xeniades is supposed to have remarked "A good spirit has entered my house.
"[7] It is impossible to say whether any of this is accurate or even whether Xeniades actually existed, but another Cynic, Cleomenes, also made use of the theme of Diogenes being sold into slavery,[8] and Xeniades was supposed to have been the man who persuaded Monimus to become a follower of Diogenes.
