Sophistic & Logic
This stratagem relies on the "petitio principii" fallacy, used here as an argument against the opponent.
Original text
If your opponent requires you to admit something from which the point in dispute will immediately follow, you must refuse to do so, declaring that it is a petitio principii. For he and the audience will regard a proposition which is near akin to the point in dispute as identical with it, and in this way you deprive him of his best argument.
