Institutio Oratoria

When the ambiguity lies in words used by others, they can never do us any harm, unless he who uttered them be unknown or dead; I will give two illustrations of my meaning:

A cry was heard at night, 'Be on your guard against the establishment of a tyranny';

on being asked who had poisoned him, he replied: 'It is not fit that you should know.'

Finally, whereas our own words and deeds can only be justified by their intention, the deeds and words of others can be disposed of in a number of different ways. My remarks on this subject have, I think, been confined to one very important class of conjectural cases, but something of what I have said will apply to all cases. For example, in cases concerned with

But even in the case of an accusation of theft, just as in an accusation of murder, we enquire both into the act and the author, while in cases concerned with loans and deposits there are also two questions (though these are always distinct from one another), namely, whether the money was delivered and whether it has been repaid. Cases of adultery are marked by the following peculiarity, that, as a rule, the safety of two persons is involved, and it is necessary to say something of the past life of both, although some have raised the question whether both parties should be defended together. The line to be taken must depend on the circumstances of the individual case: if the defence of one party lends support to the defence of the other, I should defend them conjointly; if the reverse is the case, I should treat the two cases separately.

However, that no one may think me somewhat hasty in saying that two persons are as a rule involved in charges of adultery, I would point out that I would not assert that this is always the case. The woman alone may be accused of adultery with a person unknown: we may say,

Gifts were found in the house, and money from some unknown source, and love-letters whose destination cannot be ascertained.

The case is similar in accusations of forgery: for either there are several accused or only

But the custom prevalent in the schools of regarding everything not definitely stated in the theme as being in the speaker's favour, [*](cp. IV. ii. 28. As the examples which follow show, the declaimer assumes that his imaginary opponent has no good evidence to support his case: i.e. no witness, no informer, no weapons, no bodyguard. ) is likely to prove harmful to students destined for practice in the courts. You bring a charge of adultery.

Who is your witness? who is your informer?

What was my reward? who was my accomplice?

Where did I buy the poison, and from whom? When did I buy it, what was the price, and whom did I employ to administer it?

Where are my weapons, and what bodyguards have I ever collected?
