Book 2
24.4
Another topic is that of constructing or destroying by exaggeration, which takes place when the speaker, without having proved that any crime has actually been committed, exaggerates the supposed fact; for it makes it appear either that the accused is not guilty, when he himself exaggerates it, or that he is guilty, when it is the accuser who is in a rage. Therefore there is no enthymeme; for the hearer falsely concludes that the accused is guilty or not, although neither has been proved.

Another fallacy is that of the sign, for this argument also is illogical. For instance, if one were to say that those who love one another are useful to States, since the love of Harmodius and Aristogiton overthrew the tyrant Hipparchus; or that Dionysius is a thief, because he is a rascal; for here again the argument is inconclusive; not every rascal is a thief although every thief is a rascal.
