“Idiot is a word derived from the Greek ἰδιώτης, idiōtēs ("a private citizen", "individual"), from ἴδιος, idios ("private", "one's own"). In ancient Greece, people who were not capable of engaging in the public sphere were considered "idiotes", in contrast to the public citizen, or "polites". An idiot in Athenian democracy was someone who was characterized by self-centeredness and concerned almost exclusively with private—as opposed to public—affairs."
