o possess them and are at the same time high-spirited and
magnanimous are not so constituted by nature as to live orderly and in a
peaceful and settled manner; they are driven any way by their impulses,
and all solid principle goes out of them.

Very true, he said.

On the other hand, those steadfast natures which can better be depended
upon, which in a battle are impregnable to fear and immovable, are
equally immovable when there is anything to be learned; they are
always in a torpid state, and are apt to yawn and go to sleep over any
intellectual toil.

Quite true.

And yet we were saying that both qualities were necessary in those to
whom the higher education is to be imparted, and who are to share in any
office or command.

Certainly, he said.

And will they be a class which is rarely found?

Yes, indeed.

Then the aspirant must not only be tested in those labours and dangers
and pleasures which we mentioned before, but there is another kind of
probation which we did not mention--he must be exercised also in many
kinds of knowledge, to see whether the soul will be able to endure the
highest of all, or will faint under them, as in any other studies and
exercises.

Yes, he said, you are quite right in testing him. But what do you mean
by the highest of all knowledge?

You may remember, I said, that we divided the soul into three parts; and
distinguished the several natures of justice, temperance, courage, and
wisdom?

Indeed, he said, if I had forgotten, I should not deserve to hear more.

And do you remember the word of caution which preceded the discussion of
them?

To what do you refer?

We were saying, if I am not mistaken, that he who wanted to see them in
their perfect beauty must take a longer and more circuitous way, at
the end of which they would appear; but that we could add on a popular
exposition of them on a level with the discussion which had preceded.
And you replied that such an exposition would be enough for you, and so
the enquiry was continued in what to me seemed to be a very inaccurate
manner; whether you were satisfied or not, it is for you to say.

Yes, he said, I thought and the others thought that you gave us a fair
measure of truth.

But, my friend, I said, a measure of such things which in any degree
falls short of the whole truth is not fair measure; for nothing
imperfect is the measure of anything, although persons are too apt to be
contented and think that they need
