ng to look on animals and plants and the light of the sun, but are
able to perceive even with their weak eyes the images in the water
(which are divine), and are the shadows of true existence (not shadows
of images cast by a light of fire, which compared with the sun is only
an image)--this power of elevating the highest principle in the soul to
the contemplation of that which is best in existence, with which we may
compare the raising of that faculty which is the very light of the body
to the sight of that which is brightest in the material and visible
world--this power is given, as I was saying, by all that study and
pursuit of the arts which has been described.

I agree in what you are saying, he replied, which may be hard to
believe, yet, from another point of view, is harder still to deny.
This, however, is not a theme to be treated of in passing only, but
will have to be discussed again and again. And so, whether our
conclusion be true or false, let us assume all this, and proceed at
once from the prelude or preamble to the chief strain, and describe
that in like manner. Say, then, what is the nature and what are the
divisions of dialectic, and what are the paths which lead thither; for
these paths will also lead to our final rest?

Dear Glaucon, I said, you will not be able to follow me here, though I
would do my best, and you should behold not an image only but the
absolute truth, according to my notion. Whether what I told you would
or would not have been a reality I cannot venture to say; but you would
have seen something like reality; of that I am confident.

Doubtless, he replied.

But I must also remind you, that the power of dialectic alone can
reveal this, and only to one who is a disciple of the previous sciences.

Of that assertion you may be as confident as of the last.

And assuredly no one will argue that there is any other method of
comprehending by any regular process all true existence or of
ascertaining what each thing is in its own nature; for the arts in
general are concerned with the desires or opinions of men, or are
cultivated with a view to production and construction, or for the
preservation of such productions and constructions; and as to the
mathematical sciences which, as we were saying, have some apprehension
of true being--geometry and the like--they only dream about being, but
never can they behold the waking reality so long as they leave the
hypotheses which they use unexam
