Clitophon, son of Aristonymus (Greek: Κλειτόφων Ἀριστωνύμου, Kleitóphōn Aristōnúmou, also transliterated as Cleitophon; mid-5th century – late 5th or early 4th century BCE) was an ancient Athenian oligarchic statesman and intellectual. His involvement in Athenian politics helped pave the way for the rule of the Four Hundred following the Athenian coup of 411 BCE.[1] Clitophon also appears in the writing of Plato, and presents a philosophy of "thoroughgoing normative relativism"[1] in a brief role in the Republic.[2]
