yed 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 any man.

And surely, he replied, no one will ever prove that the souls of men
become more unjust in consequence of death.

But if some one who would rather not admit the immortality of the soul
boldly denies this, and says that the dying do really become more evil
and unrighteous, then, if the speaker is right, I suppose that
injustice, like disease, must be assumed to be fatal to the unjust, and
that those who take this disorder die by the natural inherent power of
destruction which evil has, and which kills them sooner or later, but
in quite another way from that in which, at present, the wicked receive
death at the hands of others as the penalty of their deeds?

Nay, he said, in that case injustice, if fatal to the unjust, will not
be so very terrible to him, for he will be delivered from evil. But I
rather suspect the opposite to be the truth, and that injustice which,
if it have the power, will murder others, keeps the murderer
alive--aye, and well awake too; so far removed is her dwelling-place
from being a house of death.

True, I said; if the inherent natural vice or evil of the soul is
unable to kill or destroy her, hardly will that which is appointed to
be the destruction of some other body, destroy a soul or anything else
except that of which it was appointed to be the destruction.

Yes, that can hardly be.

But the soul which cannot be destroyed by an evil, whether inherent or
external, must exist f
