Plato: The Republic

10. BOOK X (continued)

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.
