But while examples may at times, as in the last instance, apply in their entirety, at times we shall argue from the greater to the less or from the less to the greater.
Cities have been overthrown by the violation of the marriage bond. What punishment then will meet the case of adultery?
Fluteplayers have been recalled by the state to the city which they had left. How much more then is it just that leading citizens who have rendered good service to their country should be recalled from that exile to which they have been driven by envy.[*]( cp. Liv. ix. 30. The flute-players employed in public worship migrated to Tibur because deprived of an oldestablished privilege, but were brought back by stratagem, after their hosts had made them drunk. )
Arguments from unlikes are most useful in exhortation. Courage is more remarkable in a woman than in a man. Therefore, if we wish to kindle someone's ambition to the performance of heroic deeds, we shall find that parallels drawn from the cases of Horatius and Torquatus will carry less weight than that of the woman by whose hand Pyrrhus was slain, and if we wish to urge a man to meet death, the cases of Cato and Scipio will carry less weight than that of Lucretia. These are however arguments from the greater to the less.
Let me then give you separate examples of these classes of argument from the pages of Cicero; for where should I find better? The following passage from the pro Murena [*]( viii. 17. Sulpicius, one of Murena's accusers and an unsuccessful candidate for the consulship, had sought to depreciate Murena's birth. Cicero urges that even if Sulpicius' statements were true they would be irrelevant and cites his own case to support his argument. ) is an instance of argument from the like:
For it happened that I myself when a candidate had two patricians as competitors, the one a man of the most unscrupulous and reckless character, the other a most excellent and respectable citizen. Yet I defeated Catiline by force of merit and Galba by myv4-6 p.279popularity.
The pro Milone [*](iii. 7.) will give us an example of argument from the greater to the less:
They say that he who confesses to having killed a man is not fit to look upon the light of day. Where is the city in which men are such fools as to argue thus? It is Rome itself, the city whose first trial on a capital charge was that of Marcus Horatius, the bravest of men, who, though the city had not yet attained its freedom, was none the less acquitted by the assembly of the Roman people, in spite of the fact that he confessed that he had slain his sister with his own hand.The following [*](pro Mil. xxvii. 72. ) is an example of argument from the less to the greater:
I killed, not Spurius Maelius, who by lowering the price of corn and sacrificing his private fortune fell under the suspicion of desiring to make himself king, because it seemed that he was courting popularity with the common people overmuch,and so on till we come to,
No, the man I killed (for my client would not shrink from the avowal, since his deed had saved his country) was he who committed abominable adultery even in the shrines of the gods; then follows the whole invective against Clodius.
