Now, I want to know, what is that which is not wisdom, and of which wisdom
is the science?

You are just falling into the old error, Socrates, he said. You come
asking in what wisdom or temperance differs from the other sciences, and
then you try to discover some respect in which they are alike; but they are
not, for all the other sciences are of something else, and not of
themselves; wisdom alone is a science of other sciences, and of itself.
And of this, as I believe, you are very well aware: and that you are only
doing what you denied that you were doing just now, trying to refute me,
instead of pursuing the argument.

And what if I am? How can you think that I have any other motive in
refuting you but what I should have in examining into myself? which motive
would be just a fear of my unconsciously fancying that I knew something of
which I was ignorant. And at this moment I pursue the argument chiefly for
my own sake, and perhaps in some degree also for the sake of my other
friends. For is not the discovery of things as they truly are, a good
common to all mankind?

Yes, certainly, Socrates, he said.

Then, I said, be cheerful, sweet sir, and give your opinion in answer to
the question which I asked, never minding whether Critias or Socrates is
the person refuted; attend only to the argument, and see what will come of
the refutation.

I think that you are right, he replied; and I will do as you say.
