Institutio Oratoria

For at times we may include in a single proposition the refutation of an argument which our opponent has constructed of a number of different points. For instance, if the accuser allege that the accused had a number of motives for committing a crime, we may make a general denial of the fact without dealing singly with each alleged motive, because the fact that a man has had a motive for committing a

It will however as a rule be expedient for the prosecution to employ massed arguments, and for the accused to refute them in detail. We must, however, also consider the manner in which we should refute the arguments of our opponent. If his statements be obviously false, it will be sufficient to deny them. This is done by Cicero in the pro Cluentio, [*](lx. 168.) where he denies that the man alleged by the accuser to have fallen dead on the spot after drinking the contents of the cup, died on the same day.

Again, it requires no skill to rebut arguments which are obviously contradictory, superfluous or foolish, and consequently I need give no examples nor instructions as to the method to be employed. There is also the type of charge which is known as obscure, where it is alleged that an act was committed in secret without witnesses or any evidence to prove it: this suffers from an inherent weakness, since the fact that our opponent can produce no proof is sufficient for our purpose: the same applies to arguments which are irrelevant to the case.

It is, however, sometimes an orator's duty to make it appear that some argument of his opponent is contradictory or irrelevant or incredible or superfluous or really favourable to his own client. Oppius [*](cp. § 21 and v. x 69. ) is charged with having embezzled the supplies intended to feed the troops. It is a serious charge, but Cicero shows that it contradicts other charges, since the same accusers also charged Oppius with desiring to corrupt the army by bribes.

The accuser of Cornelius offers to produce witnesses to show that he read out the law when tribune [*](cp. IV. ii. 13. ) : Cicero makes this argument

As regards other charges, they may all be dealt with by very similar methods. For they may be demolished either by conjecture, when we shall consider whether they are true, by definition, when we shall examine whether they are relevant to the case, by quality, when we shall consider whether they are dishonourable, unfair, scandalous, inhuman, cruel, or deserve any other epithet coming under the head of quality.

Such questions have to be considered, not merely in connection with the statement of the charges or the reasons alleged, but with reference to the nature of the case in its entirety. For instance, the question of cruelty is considered with regard to the charge of high treason brought against Rabirius [*]( Rabirius was accused of causing the death of Saturninus forty years after the event. ) by Labienus; of inhumanity in the case of Tubero who accused Ligarius when he was an exile and attempted to prevent Caesar from pardoning him; of arrogance as in the case of the charge brought against Oppius [*]( P. Oppius, quaestor to M. Aurelius Cotta in Bithynia, was charged by Cotta in a letter to the senate with misappropriation of supplies for the troops and with an attempt on his life. Cicero defended him in 69 B.C. The speech is lost. ) on the strength of a letter of Cotta.

Similarly, it may be shown that charges are hasty, insidious or vindictive. The strongest argument, however, which can be brought against a charge is that it involves peril to the community or to the judges themselves; we find an example of the former in the pro Tullio, [*](cp. IV. ii. 131. The speech is lost. ) where Cicero says

Who ever laid down such a principle as this, or who could be allowed, without grave peril to the community, to kill a man, just because he asserts that he feared that he himself might be

killed by him?

On the other hand there are certain arguments which at times may best be treated with contempt, as being trivial or irrelevant. This course is frequently pursued by Cicero, indeed this affectation of indifference is sometimes carried so far that we trample disdainfully under foot arguments which we should never succeed in refuting by counter-argument.

Since, however, the majority of such arguments are based on similarity, we must make diligent search to discover if any discrepancy is to be found in what is put forward. It is easy to do this where points of law are concerned. For the law was drafted to cover cases quite other than the present, and consequently it is all the easier to show the difference between case and case. As to parallels drawn from dumb animals or inanimate objects, they are easy to make light of.
