CLEINIAS: Certainly.
ATHENIAN: And a physician who is ignorant about the body, that is to say, who knows not that which we just now called health, or a general who knows not victory, or any others who are ignorant of the particulars of the arts which we mentioned, cannot be said to have understanding about any of these matters.
CLEINIAS: They cannot.
ATHENIAN: And what would you say of the state? If a person proves to be ignorant of the aim to which the statesman should look, ought he, in the first place, to be called a ruler at all; and further, will he ever be able to preserve that of which he does not even know the aim?
CLEINIAS: Impossible.
ATHENIAN: And therefore, if our settlement of the country is to be perfect, we ought to have some institution, which, as I was saying, will tell what is the aim of the state, and will inform us how we are to attain this, and what law or what man will advise us to that end. Any state which has no such institution is likely to be devoid of mind and sense, and in all her actions will proceed by mere chance.
CLEINIAS: Very true.
ATHENIAN: In which, then, of the parts or institutions of the state is any such guardian power to be found? Can we say?
CLEINIAS: I am not quite certain, Stranger; but I have a suspicion that you are referring to the assembly which you just now said was to meet at night.
ATHENIAN: You understand me perfectly, Cleinias; and we must assume, as the argument implies, that this council possesses all virtue; and the beginning of virtue is not to make mistakes by guessing many things, but to look steadily at one thing, and on this to fix all our aims.
