Plato, Cratylus

Socrates
And whose work will the hole-maker use when he uses the borer?

Hermogenes
The smith's.

Socrates
And is every one a smith, or he who has the skill?

Hermogenes
He who has the skill.

Socrates
And whose work will the teacher use when he uses the name?

Hermogenes
I cannot tell that, either.

Socrates
And can you not tell this, either, who gives us the names we use?

Hermogenes
No.

Socrates
Do you not think it is the law that gives them to us?

Hermogenes
Very likely.
