anything should have eyes rather than no eyes?

There can be no question of that.

And are not those who are verily and indeed wanting in the knowledge
of the true being of each thing, and who have in their souls no clear
pattern, and are unable as with a painter's eye to look at the absolute
truth and to that original to repair, and having perfect vision of the
other world to order the laws about beauty, goodness, justice in this,
if not already ordered, and to guard and preserve the order of them--are
not such persons, I ask, simply blind?

Truly, he replied, they are much in that condition.

And shall they be our guardians when there are others who, besides being
their equals in experience and falling short of them in no particular of
virtue, also know the very truth of each thing?

There can be no reason, he said, for rejecting those who have this
greatest of all great qualities; they must always have the first place
unless they fail in some other respect.

Suppose then, I said, that we determine how far they can unite this and
the other excellences.

By all means.

In the first place, as we began by observing, the nature of the
philosopher has to be ascertained. We must come to an understanding
about him, and, when we have done so, then, if I am not mistaken, we
shall also acknowledge that such an union of qualities is possible, and
that those in whom they are united, and those only, should be rulers in
the State.

What do you mean?

Let us suppose that philosophical minds always love knowledge of a sort
which shows them the eternal nature not varying from generation and
corruption.

Agreed.

And further, I said, let us agree that they are lovers of all true
being; there is no part whether greater or less, or more or less
honourable, which they are willing to renounce; as we said before of the
lover and the man of ambition.

True.

And if they are to be what we were describing, is there not another
quality which they should also possess?

What quality?

Truthfulness: they will never intentionally receive into their mind
falsehood, which is their detestation, and they will love the truth.

Yes, that may be safely affirmed of them.

'May be,' my friend, I replied, is not the word; say rather 'must be
affirmed:' for he whose nature is amorous of anything cannot help loving
all that belongs or is akin to the object of his affections.

Right, he said.

And is there anything more akin to wisd
