Diogenes and the Cynics
The Famous Stories, Checked

Diogenes of Sinope is the philosopher people remember for his stunts: the lamp in daylight, the home in a jar, the insult to Alexander the Great. Nearly all of it reaches us through anecdotes. The Internet Encyclopedia of Philosophy puts it plainly: “The evidence regarding the Cynics is limited to apothegms, aphorisms, and ancient hearsay; none of the many Cynic texts have survived.” Our main source is Diogenes Laertius, Lives of Eminent Philosophers, Book VI, in R. D. Hicks’s 1925 translation. Hicks provisionally dates that work to “the earlier decades of the third century” AD, while Diogenes of Sinope lived from about 404 to 323 BC (dates vary), so the gap is more than five centuries. Here are eight famous claims, checked.

1. “Diogenes walked around with a lamp looking for an honest man”

Partly true The lamp is in the source; the word “honest” is not. In Hicks’s translation: “He lit a lamp in broad daylight and said, as he went about, ‘I am looking for a man.’” The Greek word is anthrōpos, a human being, and there is no adjective with it in the Greek text. The Internet Encyclopedia renders it “I am searching for a human being”. We searched Hicks’s full Book VI for “honest”: it appears three times, and never in the lamp story.

The same joke is told about someone else in an older written text. The Roman poet Phaedrus, who wrote under the early Roman emperors, has the fable-teller Aesop walking through the forum at midday with a lamp and saying “Hominem … quaero”, “I am looking for a human being” (our translation). His English translator, Henry Riley, placed this book of the fables “long after the time of Augustus”, noting a suggestion that it was written “as late as the reign of Caligula”, which is still long before Diogenes Laertius. Riley added: “The same story is told in Diogenes Laertius, of Diogenes the Cynic.”

2. “He told Alexander the Great to get out of his sun”

Unverified The story is told in several ancient sources, slightly differently each time: by Cicero in his Tusculan Disputations, where Diogenes asks Alexander to move “a little out of the sun” (our translation), and by Plutarch, Arrian and Diogenes Laertius. In Diogenes Laertius, Diogenes is “sunning himself” when Alexander offers him any favour, and he replies: “Stand out of my light.” In Plutarch’s Life of Alexander, in the English edition edited by Arthur Hugh Clough, he says: “I would have you stand from between me and the sun”, and Alexander remarks that “if he were not Alexander, he would choose to be Diogenes.”

Whether it happened, nobody can say. Diogenes Laertius records another tidy coincidence worth keeping in mind: a writer named Demetrius claimed “that on the same day on which Alexander died in Babylon Diogenes died in Corinth.”

3. “Diogenes lived in a barrel”

Partly true He lived in a container, but it was not a wooden barrel. Hicks translates: “he took for his abode the tub in the Metron”. The Greek word is pithos, which the standard Greek dictionary, Liddell–Scott–Jones, defines as a “large wine-jar”, “usu. of earthenware”. (The same entry notes that wooden ones, “casks”, existed too, so a barrel is not impossible, just not the usual meaning.) Diogenes Laertius adds that when a boy broke it, the Athenians “gave the boy a flogging and presented Diogenes with another.”

4. “He mocked Plato’s ‘featherless biped’ with a plucked chicken”

Unverified, but the target of the joke is real. Diogenes Laertius reports: “Plato had defined Man as an animal, biped and featherless, and was applauded. Diogenes plucked a fowl and brought it into the lecture-room with the words, ‘Here is Plato’s man.’” According to the same passage, the definition was then patched with “having broad nails”. Plato’s dialogue Statesman does divide animals this way; in Benjamin Jowett’s translation: “we should divide bipeds into those which have feathers and those which have not”.

5. “Diogenes invented the idea of being a citizen of the world”

Partly true The line is in the source: “Asked where he came from, he said, ‘I am a citizen of the world.’” The Greek is a single word, kosmopolitēs, the root of “cosmopolitan”. Hicks himself hedged in a footnote: “If this answer is authentic, it apparently shows that the famous term ‘cosmopolitan’ originated with Diogenes.”

The Stanford Encyclopedia calls him “the first philosopher in the West to give perfectly explicit expression to cosmopolitanism”, but not the first to have the idea: it notes that Socrates’ ideas “accelerated the development of cosmopolitanism”, and that in Plato’s Protagoras the Sophist Hippias already calls a mixed audience “fellow-citizens – by nature and not by convention”. What he meant is argued. Pauline Kleingeld and Eric Brown, in the Stanford Encyclopedia of Philosophy, read it as a refusal: Diogenes “apparently refused to agree that he owed special service to Sinope”, so that “‘I am a citizen of the cosmos’ is a negative claim”. Julie Piering, in the Internet Encyclopedia, argues for a positive reading, noting that “Diogenes does not say that he is apolis, that is, without a polis”.

One story about him does have hard evidence behind it. Diogenes Laertius says he and his father were involved in defacing the coinage of their home city, Sinope, and Piering writes: “Thanks to numismatic evidence, the adulteration of Sinopean coinage is one event about which there is certainty.”

6. “The Cynics were cynical”

Partly true They were not cynics in the modern sense, but the modern sense grew out of them. Their contempt was aimed at hypocrisy: asked where in Greece he saw good men, Diogenes answered, “Good men nowhere, but good boys at Lacedaemon”, and he mocked orators who “make a fuss about justice in their speeches, but never practise it”. What the modern word dropped is the way of life behind the contempt. Diogenes Laertius says they held that “‘Life according to Virtue’ is the End to be sought”, that they “should live frugally”, and that “Wealth and fame and high birth they despise.” Asked what was the most beautiful thing in the world, Diogenes answered “Freedom of speech.” Piering sums up the core: “virtue is a life lived in accord with nature”, and conventions “are often absurd and worthy of ridicule.” The Greek name kunikos means “dog-like”, and Diogenes embraced it. Asked why he was called a hound, he said: “I fawn on those who give me anything, I yelp at those who refuse, and I set my teeth in rascals.”

In English, the word “cynic” named the ancient school first; Merriam-Webster dates it to 1533 and the Online Etymology Dictionary to the 1550s. The meaning “sneering sarcastic person” follows by the 1590s, according to the Online Etymology Dictionary. As Merriam-Webster puts it: “In English, however, cynic and cynical have more to do with distrust of motives than shamelessness.” The adjective cynical first meant “resembling Cynic philosophers” and, according to the Online Etymology Dictionary, by the 1660s had “shaded into” the general sense of doubting “the sincerity or value of social usages or personal character or motives”.

7. “Antisthenes founded the Cynic school”

Disputed Ancient tradition says so. Diogenes Laertius makes Antisthenes, a companion of Socrates, the teacher of Diogenes, and writes that he “gave the impulse to the indifference of Diogenes, the continence of Crates, and the hardihood of Zeno”. Piering writes that Diogenes Laertius identifies him “controversially as the original Cynic”: Antisthenes’ contemporaries, “such as Plato and Xenophon”, do not call him a dog, and the story of Diogenes as his pupil “has been met with suspicion, especially given the likely dates of Diogenes’ arrival in Athens and Antisthenes’ death”. She adds that this silence “lends some credence to the notion that the term kunikos was applied to Antisthenes posthumously”. Even the origin of the name “Cynic” is, in her words, “a point of contention”.

8. “The Stoics grew out of the Cynics”

Partly true According to the Stanford Encyclopedia, the Stoic school “was founded around 300 BCE by Zeno of Citium”, who “also studied under the Cynic Crates and was influenced by the teachings of Plato’s Academy and the Megarian School”. The Internet Encyclopedia calls the founding of Stoicism “the first and most direct Cynic influence”. Diogenes Laertius even says the Cynics held their view of virtue “exactly like the Stoics”, and calls Cynicism “a short cut to virtue”. The story of how Zeno met Crates, in a bookshop where the bookseller pointed at Crates and said “Follow yonder man”, is one Piering thinks “may strike one as too propitious to be historically accurate”.

Crates, whom Diogenes Laertius lists among Diogenes’s pupils (one of his sources disagreed), is said to have given away his wealth. The philosopher Hipparchia, whom Piering calls “the first known woman Cynic philosopher”, insisted on marrying him and then shared his way of life. When a critic mocked her for leaving the loom, she asked whether he supposed she had been “ill advised about myself, if instead of wasting further time upon the loom I spent it in education?”

How Diogenes died is as uncertain as the rest. Diogenes Laertius says he was “nearly ninety years old” and that “there are several different accounts”, including a raw octopus and a dog bite. Piering’s view: “it is more likely that he died of old age.”

Our reading

The popular Diogenes is a grumpy truth-teller with a lantern. The Diogenes of the sources is stranger and harder to pin down: a man who lived as a public argument against convention, whose stories were collected, polished and probably improved over five centuries. Our verdict on most of them is that they are good stories about a real person, not records of what he did.
