Institutio Oratoria

When, however, we are confronted by decrees of the senate, or ordinances of emperors or magistrates, there is no remedy, unless we can make out that there is some difference, however small, between the cases, or that the same persons or persons holding the same powers have made some subsequent enactment reversing the former decision. Failing this, there will be no case for judgment.

With regard to rumour and common report, one party will call them the verdict of public opinion and the testimony of the world at large; the other will describe them as vague talk based on no sure authority, to which malignity has given birth and credulity increase, an ill to which even the most innocent of men may be exposed by the deliberate dissemination of falsehood on the part of their enemies. It will be easy for both parties to produce precedents to support their arguments.

A like situation arises in the case of evidence extracted by torture: one party will style torture an infallible method of discovering the truth, while the other will allege that it also often results in false confessions, since with some their capacity of endurance makes lying an easy thing, while with others weakness makes it a necessity. It is hardly worth my while to say more on the subject, as the speeches both of ancient and modern orators are full of this topic.

Individual cases may however involve special considerations in this connexion. For if the point at issue is whether torture should be applied, it will make all the difference who it is who demands or offers it, who it is that is to be subjected to torture, against whom the evidence thus sought will tell, and what is the motive for the demand. If on the other hand torture has already been applied, it will make all the difference who was in charge of the proceedings, who was the victim and what the nature of the torture, whether the confession was credible or consistent, whether the witness stuck to his first statement or changed it under the influence of pain, and whether he made it at the beginning of the torture or only after it had continued some time. The

It is also frequently necessary to speak against documents, for it is common knowledge that they are often not merely rebutted, but even attacked as forgeries. But as this implies either fraud or ignorance on the part of the signatories, it is safer and easier to make the charge one of ignorance, because by so doing we reduce the number of the persons accused.

But our proceedings as a whole will draw their arguments from the circumstances of the case at issue. For example, it may be incredible that an incident occurred as stated in the documents, or, as more often happens, the evidence of the documents may be overthrown by other proofs which are likewise of an inartificial nature; if, for example, it is alleged that the person, whose interests are prejudiced by the document, or one of the signatories was absent when the document was signed, or deceased before its signature, or if the dates disagree, or events preceding or following the writing of the document are inconsistent with it. Even a simple inspection of a document is often sufficient for the detection of forgery.

With regard to oaths, [*]( An oath might be taken by one of the parties as an alternative to evidence. In court such an oath might be taken only on the proposal of the adversary; the litigant might not swear on his own initiative, although an oath might be taken voluntarily before the case came into court. The matter of the oath rested with the profferer, and the taking of such a proffered oath meant victory for the swearer. ) parties either offer to take an oath themselves, or refuse to accept the oath of their opponent, demand that their opponent should take an oath or refuse to comply with a similar demand when proffered to themselves. To offer to take an oath unconditionally without demanding that one's opponent should likewise take an oath is as a rule a sign of bad faith.

If, however, anyone should take this course, he will defend his action by appealing to the blamelessness of his life

The man who refuses to accept his opponent's offer to take an oath, will allege that the inequality of their respective conditions are not the same for both parties and will point out that many persons are not in the least afraid of committing perjury, even philosophers having been found to deny that the gods intervene in human affairs; and further that he who is ready to take an oath without being asked to do so, is really proposing to pass sentence on his own case and to show what an easy and trivial thing he thinks the oath which he offers to take.

On the other hand the man who proposes to put his opponent on oath appears to act with moderation, since he is making his adversary a judge in his own case, while he frees the actual judge from the burden of coming to a decision, since the latter would assuredly prefer to rest on another man's oath than on his own.

This fact makes the refusal to take an oath all the more difficult, unless indeed the affair in question be of such a nature that it cannot be supposed that the facts are known to the person asked to take the oath. Failing this excuse, there

But in my young days advocates grown old in pleading used to lay it down as a rule that we should never be in a hurry to propose that our opponent should take an oath, just as we should never allow him the choice of a judge [*]( The choice of the single iudex in civil cases rested with the plaintiff, though the defendant had the right to refuse the person proposed. ) nor select our judge from among the supporters of the opposite side: for if it is regarded as a disgrace to such a supporter [*]( Not an actual advocate, but a supporter and adviser on points of law. ) to say anything against his client, it is surely a still worse disgrace that he should do anything that will harm his client's case.

It is, however, the evidence that gives the greatest trouble to advocates. Evidence may be given either in writing or orally by witnesses present in court. Documentary evidence is easier to dispose of. For it is likely that the deponent was less ashamed of himself in the presence of a small number of witnesses, and his absence from court is attacked as indicating a lack of confidence. If we cannot call the character of the deponent in question, we may attack the witnesses to his signature.

Further there is always a certain tacit prejudice against documentary evidence, since no one can be forced to give such evidence save of his own free will, whereby he shows that he harbours unfriendly feelings towards the person against whom he bears

The task of dealing with the evidence of witnesses present in court is, however, one of great difficulty, and consequently whether defending or impugning them the orator employs a twofold armoury in the shape of a set speech and examination. [*](Interrogatio includes both the examination in chief and cross-examination. ) In set speeches it is usual to begin with observations either on behalf of or against witnesses in general.

In so doing we introduce a commonplace, since one side will contend that there can be no stronger proof than that which rests on human knowledge, while the other, in order to detract from their credibility, will enumerate all the methods by which false evidence is usually given.

The next procedure is the common practice of making a special attack, which all the same involves impugning the validity of evidence given by large numbers of persons. We know, for instance, that the evidence of entire nations [*](e.g. in cases of extortion, where a whole province might give evidence against the accused. ) and whole classes of evidence have been disposed of by advocates. For example, in the case of hearsay evidence, it will be urged that those who produce such evidence are not really witnesses, but are merely reporting the words of unsworn persons, while in cases of extortion, those who swear that they paid certain sums to the accused are to be regarded not as witnesses, but as parties to the suit.

Sometimes however the advocate will direct his speech against single individuals. Such a form of attack may be found in many speeches, sometimes embedded in

The whole subject, therefore, demands a thorough investigation, as the task which we have in hand is the complete education of an orator. Otherwise the two books written on this subject by Domitius Afer would suffice. I attended his lectures when he was old and I was young, and consequently have the advantage not merely of having read his book, but of having heard most of his views from his own lips. He very justly lays down the rule that in this connexion it is the first duty of an orator to make himself thoroughly acquainted with the case, a remark which of course applies to all portions of a speech.

How such knowledge may be acquired I shall explain when I come to the appropriate portion of this work. [*](XII. viii.) This knowledge will suggest material for the examination and will supply weapons ready to the speaker's hand: it will also indicate to him the points for which the judge's mind must be prepared in the set speech. For it is by the set speech that the credit of witnesses should be established or demolished, since the effect of evidence on the individual judge depends on the extent to which he has been previously influenced in the direction of believing the witness or the reverse. And since there are two classes of witnesses [*]( In civil cases evidence was as a rule voluntary; in criminal cases the accuser might subpoena witnesses, while the defence was restricted to voluntary testimony. )
