But surely, Thrasymachus, the arts are the superiors and rulers of their own subjects?
To this he assented with a good deal of reluctance.
Then, I said, no science or art considers or enjoins the interest of the stronger or superior, but only the interest of the subject and weaker?
He made an attempt to contest this proposition also, but finally acquiesced.
Then, I continued, no physician, in so far as he is a physician, considers his own good in what he prescribes, but the good of his patient; for the true physician is also a ruler having the human body as a subject, and is not a mere money-maker; that has been admitted?
Yes.
And the pilot likewise, in the strict sense of the term, is a ruler of sailors and not a mere sailor?
That has been admitted.
And such a pilot and ruler will provide and prescribe for the interest of the sailor who is under him, and not for his own or the ruler’s interest?
He gave a reluctant ‘Yes.’
Then, I said, Thrasymachus, there is no one in any rule who, in so far as he is a ruler, considers or enjoins what is for his own interest, but always what is for the interest of his subject or suitable to his art; to that he looks, and that alone he considers in everything which he says and does.
When we had got to this point in the argument, and every one saw that the definition of justice had been completely upset, Thrasymachus, instead of replying to me, said: Tell me, Socrates, have you got a nurse?
Why do you ask such a question, I said, when you ought rather to be answering?
Because she leaves you to snivel, and never wipes your nose: she has not even taught you to know the shepherd from the sheep.
What makes you say that? I replied.
