Plato's Phaedrus on writing: Theuth and Thamus
Plato, Phaedrus (c. 370 BCE), translated by Benjamin Jowett
The first critique of a technology of knowledge: written words seem to speak, but asked a question, they give one unvarying answer.
Why it matters
Theuth, the Egyptian god of invention, offers King Thamus the gift of letters, promising wiser people with better memories. Thamus replies that writing will do the opposite: its users will trust to external marks rather than remember, and will seem to know much while knowing little. Socrates adds the image that has outlived the myth. Writing is like painting: its creations have the attitude of life, but if you ask them a question they preserve a solemn silence, or always give one unvarying answer.
Every new technology of knowledge has been met with some version of Thamus’ worry, and most of the time the worry has been partly right and largely outweighed. I do not think the lesson of the passage is that we should distrust tools. It is that a tool which looks like a speaker should not be mistaken for one.
Language models are interesting here precisely because they answer the objection Socrates makes: ask them a question and they reply, differently each time. What they do not do is the thing the objection was for. A written page cannot defend itself; a model can produce a defence, but the defence comes from the same process as the claim, not from anyone who stands behind it. The book was silent. The model talks, and is no more answerable for what it says.
The myth of Theuth and Thamus; writing compared with painting
Phaedrus c. 274c–276a
SOCRATES: I have heard a tradition of the ancients, whether true or not they only know; although if we had found the truth ourselves, do you think that we should care much about the opinions of men?
PHAEDRUS: Your question needs no answer; but I wish that you would tell me what you say that you have heard.
SOCRATES: At the Egyptian city of Naucratis, there was a famous old god, whose name was Theuth; the bird which is called the Ibis is sacred to him, and he was the inventor of many arts, such as arithmetic and calculation and geometry and astronomy and draughts and dice, but his great discovery was the use of letters. Now in those days the god Thamus was the king of the whole country of Egypt; and he dwelt in that great city of Upper Egypt which the Hellenes call Egyptian Thebes, and the god himself is called by them Ammon. To him came Theuth and showed his inventions, desiring that the other Egyptians might be allowed to have the benefit of them; he enumerated them, and Thamus enquired about their several uses, and praised some of them and censured others, as he approved or disapproved of them. It would take a long time to repeat all that Thamus said to Theuth in praise or blame of the various arts. But when they came to letters, This, said Theuth, will make the Egyptians wiser and give them better memories; it is a specific both for the memory and for the wit. Thamus replied: O most ingenious Theuth, the parent or inventor of an art is not always the best judge of the utility or inutility of his own inventions to the users of them. And in this instance, you who are the father of letters, from a paternal love of your own children have been led to attribute to them a quality which they cannot have; for this discovery of yours will create forgetfulness in the learners' souls, because they will not use their memories; they will trust to the external written characters and not remember of themselves. The specific which you have discovered is an aid not to memory, but to reminiscence, and you give your disciples not truth, but only the semblance of truth; they will be hearers of many things and will have learned nothing; they will appear to be omniscient and will generally know nothing; they will be tiresome company, having the show of wisdom without the reality.
PHAEDRUS: Yes, Socrates, you can easily invent tales of Egypt, or of any other country.
SOCRATES: There was a tradition in the temple of Dodona that oaks first gave prophetic utterances. The men of old, unlike in their simplicity to young philosophy, deemed that if they heard the truth even from 'oak or rock,' it was enough for them; whereas you seem to consider not whether a thing is or is not true, but who the speaker is and from what country the tale comes.
PHAEDRUS: I acknowledge the justice of your rebuke; and I think that the Theban is right in his view about letters.
SOCRATES: He would be a very simple person, and quite a stranger to the oracles of Thamus or Ammon, who should leave in writing or receive in writing any art under the idea that the written word would be intelligible or certain; or who deemed that writing was at all better than knowledge and recollection of the same matters?
PHAEDRUS: That is most true.
SOCRATES: I cannot help feeling, Phaedrus, that writing is unfortunately like painting; for the creations of the painter have the attitude of life, and yet if you ask them a question they preserve a solemn silence. And the same may be said of speeches. You would imagine that they had intelligence, but if you want to know anything and put a question to one of them, the speaker always gives one unvarying answer. And when they have been once written down they are tumbled about anywhere among those who may or may not understand them, and know not to whom they should reply, to whom not: and, if they are maltreated or abused, they have no parent to protect them; and they cannot protect or defend themselves.
PHAEDRUS: That again is most true.
SOCRATES: Is there not another kind of word or speech far better than this, and having far greater power--a son of the same family, but lawfully begotten?
PHAEDRUS: Whom do you mean, and what is his origin?
SOCRATES: I mean an intelligent word graven in the soul of the learner, which can defend itself, and knows when to speak and when to be silent.
PHAEDRUS: You mean the living word of knowledge which has a soul, and of which the written word is properly no more than an image?
Questions for discussion
- Thamus says writing will give its users the appearance of wisdom without the reality. Was he wrong about writing, and is he right about any technology now?
- Written words, Socrates says, give one unvarying answer when questioned. Does a search engine or a chatbot escape that complaint, or meet it in a new form?
- Plato made this argument in writing. Is that a contradiction, or does it say something about how he meant his dialogues to be read?
The text and its source
- Edition
- The Dialogues of Plato, translated by Benjamin Jowett, as transcribed in Project Gutenberg eBook #1636 (the e-text, produced by Sue Asscher, does not say which of Jowett's editions (1871, 1875 or 1892) it reproduces)

- Status
- Public domain: Plato (d. c. 347 BCE); Jowett's translation first published 1871, Jowett died 1893; the Gutenberg e-text is public domain in the US.
- Notes on the text
- Stephanus numbers are not printed in the Gutenberg e-text; the locators give the conventional Stephanus range and are approximate ("c."). Gutenberg renders dashes as "--" in this file; they are kept as in the source. Extends a few lines past 275e to 276a so that the contrast with "the living word of knowledge" is included. The Dodona exchange ("you seem to consider not whether a thing is or is not true, but who the speaker is") falls inside the passage.
