Yes.

And you admit that every thing has a good and also an evil; as ophthalmia is the evil of the eyes and disease of the whole body; as mildew is of corn, and rot of timber, or rust of copper and iron: in everything, or in almost everything, there is an inherent evil and disease?

Yes, he said.

And anything which is infected by any of these evils is made evil, and at last wholly dissolves and dies?

True.

The vice and evil which is inherent in each is the destruction of each; and if this does not destroy them there is nothing else that will; for good certainly will not destroy them, nor again, that which is neither good nor evil.

Certainly not.
