To these proof's some authorities would add those which they call pathetic or emotional. Aristotle [*](Rhet. I. ii. 4. ) indeed holds that the strongest argument in support of a speaker is that he is a good man. This no doubt is the best support, but to seem good is also of value, though the semblance is but a bad second to the reality.

Of this nature is the noble defence of Scaurus.

Quintus Varius of Sucro asserts that Aemilius Scaurus has betrayed the interests of the Roman people: Aemilius Scaurus denies it.
A similar defence is said to have been employed by Iphicrates [*]( At. Rhet. II. xxiii. 7. ) : he asked Aristophon who was accusing him on a similar charge of treason whether lie would consent to betray his country for a bribe: when Aristophon replied in the negative, he continued,
Have I then done what you would have refused to do?

We must however take the character of the judge into consideration and seek out such arguments as will appeal to him. I have already spoken of this in the rules which I laid

down for the exordium and for deliberative oratory. [*]( IV. i. 17 sq., III. viii. 36 sq. )

Another form of proof is provided by asseveration as in

I did this,
You told me this,
or
O outrageous crime!
and the like. Every pleading should contain some such asseverations; if it does not, the loss will be considerable. Still asseverations must not be regarded as supports of the first importance, since they can be produced by either party in the same case with the same emphasis.

A more forcible kind of proof is that drawn from character and supported by some plausible reason, as for instance,

It is not likely that a wounded man or one who has lost his son would accuse anyone who is not guilty, since if he accused an innocent man, he would free the real offender from all risk of punishment.
It is from such arguments that fathers seek support when pleading against their sons or one relative against another.
