Who says and can verify P2 is correct and all others are wrong?Okay, let us play this game.
Take text X. It has one correct understanding. All other are wrong with logic. Therefore you shouldn't use those, who are wrong.
P1: There is text X.
P2: It has one correct understanding with logic.
P3: All other are wrong with logic.
C: You shouldn't use those, who are wrong.
Now if you can do logic, you know that is an invalid deduction and even if you add P4 and so on, it doesn't mean, that it becomes sound.
