Book
Theaetetus
Plato · translated by Benjamin Jowett
Socrates asks the young mathematician Theaetetus a single question: what is knowledge?
The Theaetetus is Plato's dialogue on the nature of knowledge. Three answers are examined in turn: that knowledge is perception, that it is true judgement, and that it is true judgement with an account. Socrates describes his own work as that of a midwife.
This edition is the English translation by Benjamin Jowett.

PERSONS OF THE DIALOGUE: Socrates, Theodorus, Theaetetus.
Euclid and Terpsion meet in front of Euclid's house in Megara; they enter the house, and the dialogue is read to them by a servant.
EUCLID: Have you only just arrived from the country, Terpsion?
TERPSION: No, I came some time ago: and I have been in the Agora looking for you, and wondering that I could not find you.
EUCLID: As I was going down to the harbour, I met Theaetetus—he was being carried up to Athens from the army at Corinth.
EUCLID: He was scarcely alive, for he has been badly wounded; but he was suffering even more from the sickness which has broken out in the army.
EUCLID: Yes, Terpsion, he is a noble fellow; only to-day I heard some people highly praising his behaviour in this very battle.
TERPSION: No wonder; I should rather be surprised at hearing anything else of him. But why did he go on, instead of stopping at Megara?
EUCLID: He wanted to get home: although I entreated and advised him to remain, he would not listen to me; so I set him on his way, and turned back, and then I remembered what Socrates had said of him, and thought how remarkably this, like all his predictions, had been fulfilled. I believe that he had seen him a little before his own death, when Theaetetus was a youth, and he had a memorable conversation with him, which he repeated to me when I came to Athens; he was full of admiration of his genius, and said that he would most certainly be a great man, if he lived.
