[113] [cap.22] But some of those persons who have fancied that the world is everlasting, inventing a variety of new arguments, employ also such a system of reasoning as this to establish their point: they affirm that there are four principal manners in which corruption is brought about, addition, taking away, transposition, and alteration; accordingly, the number two is by the addition of the unit corrupted so as to become the number three, and no longer remains the number two; and the number four by the taking away of the unit is corrupted so as to become the number three; again, by transposition the letter Z becomes the letter H when the parallel lines which were previously horizontal = are placed perpendicularly II, and when the line which did before pass upwards I, so as to connect the two is now made horizontal, and still extended between them so as to join them. And by alteration the word οἶνος, wine, becomes ὄξος, vinegar.
