Idiot, dolt, and dullard are terms used for a mentally deficient person, or someone who acts in a self-defeating or significantly counterproductive way. The similarly used terms moron, imbecile, and cretin have all gained specialized meanings in modern times. An idiot is said to be idiotic, and to suffer from idiocy. A dunce is an idiot who is specifically incapable of learning. An idiot differs from a fool, who is considered unwise, or an ignoramus, who is simply uneducated (an ignorant person), neither of which refers to someone with low intelligence. Such words are sometimes used as mildly derisive terms of endearment as well as harshly critical insults. The word idiot is derived from the Greek ἰδιώτης, idiōtēs ("person lacking professional skill", "a private citizen", "individual"), from ἴδιος, idios ("private", "one's own"). In Latin the word idiot ("ordinary person, layman") preceded the Late Latin meaning "uneducated or ignorant person." Its modern meaning and form dates back to Middle English around the year 1300, from the Old French idiote ("uneducated or ignorant person"). In Athenian democracy an idiot was someone who was characterized by self-centeredness and concerned almost exclusively with private — as opposed to public — affairs.

- It is paltry philosophy if in the old-fashioned way one lays down rules and principles in total disregard of moral values. As soon as these appear one regards them as exceptions, which gives them a certain scientific status, and thus makes them into rules. Or again one may appeal to genius, which is above all rules; which amounts to admitting that rules are not only made for idiots, but are idiotic in themselves.
