Part 4

SOCRATES: I mean that you rate them all at the same value, whereas they are really separated by an interval, which no geometrical ratio can express.

THEODORUS: By Ammon, the god of Cyrene, Socrates, that is a very fair hit; and shows that you have not forgotten your geometry. I will retaliate on you at some other time, but I must now ask the Stranger, who will not, I hope, tire of his goodness to us, to proceed either with the Statesman or with the Philosopher, whichever he prefers.

STRANGER: That is my duty, Theodorus; having begun I must go on, and not leave the work unfinished. But what shall be done with Theaetetus?

THEODORUS: In what respect?

STRANGER: Shall we relieve him, and take his companion, the Young Socrates, instead of him? What do you advise?

THEODORUS: Yes, give the other a turn, as you propose. The young always do better when they have intervals of rest.

SOCRATES: I think, Stranger, that both of them may be said to be in some way related to me; for the one, as you affirm, has the cut of my ugly face (compare Theaet.), the other is called by my name. And we should always be on the look-out to recognize a kinsman by the style of his conversation. I myself was discoursing with Theaetetus yesterday, and I have just been listening to his answers; my namesake I have not yet examined, but I must. Another time will do for me; to-day let him answer you.

STRANGER: Very good. Young Socrates, do you hear what the elder Socrates is proposing?

YOUNG SOCRATES: I do.

STRANGER: And do you agree to his proposal?

YOUNG SOCRATES: Certainly.

STRANGER: As you do not object, still less can I. After the Sophist, then, I think that the Statesman naturally follows next in the order of enquiry. And please to say, whether he, too, should be ranked among those who have science.

YOUNG SOCRATES: Yes.

STRANGER: Then the sciences must be divided as before?

YOUNG SOCRATES: I dare say.

STRANGER: But yet the division will not be the same?

YOUNG SOCRATES: How then?

STRANGER: They will be divided at some other point.

YOUNG SOCRATES: Yes.

STRANGER: Where shall we discover the path of the Statesman? We must find and separate off, and set our seal upon this, and we will set the mark of another class upon all diverging paths. Thus the soul will conceive of all kinds of knowledge under two classes.

YOUNG SOCRATES: To find the path is your business, Stranger, and not mine.

STRANGER: Yes, Socrates, but the discovery, when once made, must be yours as well as mine.

YOUNG SOCRATES: Very good.

STRANGER: Well, and are not arithmetic and certain other kindred arts, merely abstract knowledge, wholly separated from action?

YOUNG SOCRATES: True.

STRANGER: But in the art of carpentering and all other handicrafts, the knowledge of the workman is merged in his work; he not only knows, but he also makes things which previously did not exist.

YOUNG SOCRATES: Certainly.

STRANGER: Then let us divide sciences in general into those which are practical and those which are purely intellectual.
