Yes, he said, there are all the evils which we were just now passing in
review: unrighteousness, intemperance, cowardice, ignorance.

But does any of these dissolve or destroy her?--and here do not let us
fall into the error of supposing that the unjust and foolish man, when
he is detected, perishes through his own injustice, which is an evil
of the soul. Take the analogy of the body: The evil of the body is a
disease which wastes and reduces and annihilates the body; and all the
things of which we were just now speaking come to annihilation through
their own corruption attaching to them and inhering in them and so
destroying them. Is not this true?

Yes.

Consider the soul in like manner. Does the injustice or other evil which
exists in the soul waste and consume her? Do they by attaching to the
soul and inhering in her at last bring her to death, and so separate her
from the body?

Certainly not.

And yet, I said, it is unreasonable to suppose that anything can perish
from without through affection of external evil which could not be
destroyed from within by a corruption of its own?

It is, he replied.

Consider, I said, Glaucon, that even the badness of food, whether
staleness, decomposition, or any other bad quality, when confined to
the actual food, is not supposed to destroy the body; although, if the
badness of food communicates corruption to the body, then we should say
that the body has been destroyed by a corruption of itself, which is
disease, brought on by this; but that the body, being one thing, can be
destroyed by the badness of food, which is another, and which does not
engender any natural infection--this we shall absolutely deny?

Very true.

And, on the same principle, unless some bodily evil can produce an evil
of the soul, we must not suppose that the soul, which is one thing, can
be dissolved by any merely external evil which belongs to another?

Yes, he said, there is reason in that.

Either, then, let us refute this conclusion, or, while it remains
unrefuted, let us never say that fever, or any other disease, or the
knife put to the throat, or even the cutting up of the whole body into
the minutest pieces, can destroy the soul, until she herself is proved
to become more unholy or unrighteous in consequence of these things
being done to the body; but that the soul, or anything else if not
destroyed by an internal evil, can be destroyed by an external one, is
not to be affirmed by
