Diogenes of Sinope

c. 404–c. 323 BCE · Cynicism · Ancient

Diogenes of Sinope, roughly 404 to 323 BCE, is the saint of Cynicism, a word from the Greek for dog. He is said to have been exiled from Sinope for defacing the coinage, to have lived in a jar in Athens and Corinth, to have owned almost nothing, and to have answered Alexander the Great by asking him to get out of the sunlight.

The doctrine, such as it is, says that happiness is self-sufficiency, that virtue is enough, and that shame about natural needs is the real indecency. Almost every story comes from writers centuries later. Diogenes Laertius, in the third century CE, is the main collection, and he is a biographer of anecdotes, not an archivist. The lamp in daylight, the plucked chicken offered as Plato's 'featherless biped', the barrel: these are teaching stories the Cynic tradition told about its hero.

They have a point. They are weak evidence of what was said on a given afternoon. Stoicism begins, in part, when Zeno studies with the Cynic Crates and then adds physics and logic to the shameless life. Epictetus still praises Diogenes as a model. The praise is of a legend.

No book of his survives. The cards are anecdotes in Diogenes Laertius, book 6, with the section numbers. A fifth scene was not invented. The life is full of further stories of the same kind.

You see the range of the legend in one place, and you can practise not promoting a joke into a verified quotation.

Key ideas

  • Shamelessness

    Natural needs are not disgraceful, and the disgrace is the social pretence built around them.

  • Self-sufficiency

    A good life needs as little as possible from status, property, and other people's opinions.

  • Philosophy as performance

    The teaching is the visible life, not a treatise, which is why the anecdotes are the curriculum.

Major works

  • No reliable book (4th century BCE)

    Ancient catalogues list dialogues and tragedies under his name, but the usable record is later anecdote, especially in Diogenes Laertius.

Common misreadings

  • Cynicism here is not the modern mood of sneering at everyone's motives.
  • The best stories are legends with a doctrine inside them, not minutes of a conversation.

Famous lines Diogenes of Sinope never said

Misattributed means the library does not treat the sentence as theirs. Questionable means there is a real doubt, which is not the same as a proof they never wrote it. Both are listed here.

  • Questionable

    “I am looking for a human being.”

    A famous story: Diogenes walks with a lit lamp in daylight and says he is looking for a human being. The source is centuries later. Treat it as Cynic legend with a point, not as a verified quotation.

  • Questionable

    “Alexander stood over him and said, 'Ask me for whatever you wish.' He answered, 'Stand out of my light.'”

    Diogenes Laertius 6.38. The meeting with Alexander is a Cynic set piece written centuries later. Treat it as a school's story with a point, not as a verified transcript. It is not the lamp story in 6.41.

  • Questionable

    “Asked where he came from, he answered, 'I am a citizen of the world.'”

    Diogenes Laertius 6.63. The Greek is kosmopolitēs, citizen of the cosmos. The saying is Cynic tradition reported centuries later, not a line from a book of his. It is not the modern slogan about travel.

    “When Plato defined the human being as a featherless biped and was applauded, Diogenes plucked a cock and brought it into the school, saying, 'Here is Plato's human being.'”

    Diogenes Laertius 6.40. A famous joke at Plato's definition, told centuries later. The story is Cynic legend. It is not a quotation from a dialogue, and Plato's definition is itself a report.
