Hi! Welcome to “Dusty Phrases.” You will find below an ancient phrase in one language or another, along with its English translation. You may also find the power to inspire your friends or provoke dread among your enemies.

ἓν οἶδα ὅτι οὐδὲν οἶδα
Hèn oîda hóti oudèn oîda
I know one thing, that I know nothing.
This phrase is a paraphrase from Plato, of Socrates, and the translation is tricky. It actually is tricky enough to merit its own wiki article (excerpt below):
The phrase, originally from Latin (“ipse se nihil scire id unum sciat“), is a possible paraphrase from a Greek text (see below). It is also quoted as “scio me nihil scire” or “scio me nescire“. It was later back-translated to Katharevousa Greek as “[ἓν οἶδα ὅτι] οὐδὲν οἶδα”, [hèn oîda hóti] oudèn oîda).
This is technically a shorter paraphrasing of Socrates’ statement, “I neither know nor think I know” (in Plato, Apology 21d). The paraphrased saying, though widely attributed to Plato’s Socrates in both ancient and modern times, actually occurs nowhere in Plato’s works in precisely the form “I know I know nothing.” Two prominent Plato scholars have recently argued that the claim should not be attributed to Plato’s Socrates.
Evidence that Socrates does not actually claim to know nothing can be found at Apology 29b-c, where he claims twice to know something. See also Apology 29d, where Socrates indicates that he is so confident in his claim to knowledge at 29b-c that he is willing to die for it.
That said, in the Apology, Plato relates that Socrates accounts for his seeming wiser than any other person because he does not imagine that he knows what he does not know.
… ἔοικα γοῦν τούτου γε σμικρῷ τινι αὐτῷ τούτῳ σοφώτερος εἶναι, ὅτι ἃ μὴ οἶδα οὐδὲ οἴομαι εἰδέναι.
… I seem, then, in just this little thing to be wiser than this man at any rate, that what I do not know I do not think I know either. [from the Henry Cary literal translation of 1897]
A more commonly used translation puts it, “although I do not suppose that either of us knows anything really beautiful and good, I am better off than he is – for he knows nothing, and thinks he knows. I neither know nor think I know” [from the Benjamin Jowett translation]. Whichever translation we use, the context in which this passage occurs should be considered; Socrates having gone to a “wise” man, and having discussed with him, withdraws and thinks the above to himself. Socrates, since he denied any kind of knowledge, then tried to find someone wiser than himself among politicians, poets, and craftsmen. It appeared that politicians claimed wisdom without knowledge; poets could touch people with their words, but did not know their meaning; and craftsmen could claim knowledge only in specific and narrow fields. The interpretation of the Oracle’s answer might be Socrates’ awareness of his own ignorance.
Socrates also deals with this phrase in Plato’s dialogue Meno when he says:
καὶ νῦν περὶ ἀρετῆς ὃ ἔστιν ἐγὼ μὲν οὐκ οἶδα, σὺ μέντοι ἴσως πρότερον μὲν ᾔδησθα πρὶν ἐμοῦ ἅψασθαι, νῦν μέντοι ὅμοιος εἶ οὐκ εἰδότι.
[So now I do not know what virtue is; perhaps you knew before you contacted me, but now you are certainly like one who does not know.] (trans. G. M. A. Grube)
Here, Socrates aims at the change of Meno’s opinion, who was a firm believer in his own opinion and whose claim to knowledge Socrates had disproved.
It is essentially the question that begins “post-Socratic” Western philosophy. Socrates begins all wisdom with wondering, thus one must begin with admitting one’s ignorance. After all, Socrates’ dialectic method of teaching was based on that he as a teacher knew nothing, so he would derive knowledge from his students by dialogue.
There is also a passage by Diogenes Laërtius in his work Lives and Opinions of Eminent Philosophers where he lists, among the things that Socrates used to say: “εἰδέναι μὲν μηδὲν πλὴν αὐτὸ τοῦτο εἰδέναι”, or “that he knew nothing except that he knew that very fact (i.e. that he knew nothing)”.
Again, closer to the quote, there is a passage in Plato’s Apology, where Socrates says that after discussing with someone he started thinking that:
τούτου μὲν τοῦ ἀνθρώπου ἐγὼ σοφώτερός εἰμι· κινδυνεύει μὲν γὰρ ἡμῶν οὐδέτερος οὐδὲν καλὸν κἀγαθὸν εἰδέναι, ἀλλ᾽ οὗτος μὲν οἴεταί τι εἰδέναι οὐκ εἰδώς, ἐγὼ δέ, ὥσπερ οὖν οὐκ οἶδα, οὐδὲ οἴομαι· ἔοικα γοῦν τούτου γε σμικρῷ τινι αὐτῷ τούτῳ σοφώτερος εἶναι, ὅτι ἃ μὴ οἶδα οὐδὲ οἴομαι εἰδέναι.
I am wiser than this man, for neither of us appears to know anything great and good; but he fancies he knows something, although he knows nothing; whereas I, as I do not know anything, so I do not fancy I do. In this trifling particular, then, I appear to be wiser than he, because I do not fancy I know what I do not know.
It is also a curiosity that there is more than one passage in the narratives in which Socrates claims to have knowledge on some topic, for instance on love:
How could I vote ‘No,’ when the only thing I say I understand is the art of love (τὰ ἐρωτικά)
I know virtually nothing, except a certain small subject – love (τῶν ἐρωτικῶν), although on this subject, I’m thought to be amazing (δεινός), better than anyone else, past or present
