im with two.

STRANGER: Yes, we must, if we can. And therefore let us try another
track in our pursuit of him: You are aware that there are certain menial
occupations which have names among servants?

THEAETETUS: Yes, there are many such; which of them do you mean?

STRANGER: I mean such as sifting, straining, winnowing, threshing.

THEAETETUS: Certainly.

STRANGER: And besides these there are a great many more, such as
carding, spinning, adjusting the warp and the woof; and thousands of
similar expressions are used in the arts.

THEAETETUS: Of what are they to be patterns, and what are we going to do
with them all?

STRANGER: I think that in all of these there is implied a notion of
division.

THEAETETUS: Yes.

STRANGER: Then if, as I was saying, there is one art which includes all
of them, ought not that art to have one name?

THEAETETUS: And what is the name of the art?

STRANGER: The art of discerning or discriminating.

THEAETETUS: Very good.

STRANGER: Think whether you cannot divide this.

THEAETETUS: I should have to think a long while.

STRANGER: In all the previously named processes either like has been
separated from like or the better from the worse.

THEAETETUS: I see now what you mean.

STRANGER: There is no name for the first kind of separation; of the
second, which throws away the worse and preserves the better, I do know
a name.

THEAETETUS: What is it?

STRANGER: Every discernment or discrimination of that kind, as I have
observed, is called a purification.

THEAETETUS: Yes, that is the usual expression.

STRANGER: And any one may see that purification is of two kinds.

THEAETETUS: Perhaps so, if he were allowed time to think; but I do not
see at this moment.

STRANGER: There are many purifications of bodies which may with
propriety be comprehended under a single name.

THEAETETUS: What are they, and what is their name?

STRANGER: There is the purification of living bodies in their inward and
in their outward parts, of which the former is duly effected by medicine
and gymnastic, the latter by the not very dignified art of the bath-man;
and there is the purification of inanimate substances--to this the arts
of fulling and of furbishing in general attend in a number of minute
particulars, having a variety of names which are thought ridiculous.

THEAETETUS: Very true.

STRANGER: There can be no doubt that they are thought ridiculous,
Theaetetus; but then the dialectical
