Jowett: Theaetetus 183c-184b — Crítica dos defensores da imobilidade

Theaet. Not, Theodorus, until you and Socrates have discussed the doctrine of those who say that all things are at rest, as you were proposing.

Theod. You, Theaetetus, who are a young rogue, must not instigate your elders to a breach of faith, but should prepare to answer Socrates in the remainder of the argument.

Theaet. Yes, if he wishes ; but I would rather have heard about the doctrine of rest.

Theod. Invite Socrates to an argument — invite horsemen to the open plain ; do but ask him, and he will answer.

Soc. Nevertheless, Theodorus, I am afraid that I shall not be able to comply with the request of Theaetetus.

Theod. Not comply ! for what reason ?

Soc. My reason is that I have a kind of reverence ; not so much for Melissus and the others, who say that “All is one and at rest,” as for the great leader himself, Parmenides, venerable and awful, as in Homeric language he may be called ; — him I should be ashamed to approach in a spirit unworthy of him. I met him when he was an old man, and I was a mere youth, and he appeared to me to have a glorious depth of mind. And I am afraid that we may not understand his words, and may be still further from understanding his meaning ; above all I fear that the nature of knowledge, which is the main subject of our discussion, may be thrust out of sight by the unbidden guests who will come pouring in upon our feast of discourse, if we let them in — besides, the question which is now stirring is of immense extent, and will be treated unfairly if only considered by the way ; or if treated adequately and at length, will put into the shade the other question of knowledge. Neither the one nor the other can be allowed ; but I must try by my art of midwifery to deliver Theaetetus of his conceptions about knowledge.

Theaet. Very well ; do so if you will.
