Institutio Oratoria

Fortune sometimes is so kind that a witness gives an answer involving some inconsistency, while at times (and this is a more frequent occurrence) one witness contradicts another. But acute examination methodically conducted will generally reach the same result which is so often reached by chance.

There are also a number of points strictly irrelevant to the case on which questions may be put with advantage. We may for example ask questions about the past life of other witnesses or about the witness' own character, with a view to discovering whether they can be charged with some disgraceful conduct, or degrading occupation, with friendship with the prosecutor or hostility toward the accused, since in replying to such questions they may say something which will help our cause or may be convicted

since a witness will often launch some smart repartee in answering counsel for the defence and thereby win marked favour from the audience in general. Secondly, we must put our questions as far as possible in the language of everyday speech that the witness, who is often an uneducated man, may understand our meaning, or at any rate may have no opportunity of saying that he does not know what we mean, a statement which is apt to prove highly disconcerting to the examiner.

I must however express the strongest disapproval of the practice of sending a suborned witness to sit on the benches of the opposing party, in order that on being called into the witness-box from that quarter he may thereby do all the more damage to the case for the accused by speaking against the party with whose adherents he was sitting or, while appearing to help him by his testimony, deliberately giving his evidence in such an extravagant and exaggerated manner, as not only to detract from the credibility of his own statements, but to annul the advantage derived from the evidence of those who were really helpful. I mention this practice not with a view to encourage it, but to secure its avoidance. Documentary evidence is not frequently in conflict with oral. Such a circumstance may be turned to advantage by either side. For one party will rest its case on the fact that the witness is speaking on oath, the other on the unanimity of the signatories. [*]( An over-statement, since in many cases the signatories could only testify that the statement was that actually made by the deponent; with its truth they were not necessarily concerned. )

Again there is often a conflict between the evidence and the arguments. One party will argue that the witnesses know the facts and are bound by the

Such problems are common to a number of cases, and are and will always be the subject of vehement debate. Sometimes there are witnesses on both sides and the question arises with regard to themselves as to which are the more respectable in character, or with regard to the case, which have given the more credible evidence, with regard to the parties to the case, which has brought the greater influence to bear on the witnesses.

If to this kind of evidence anyone should wish to add evidence of the sort known as supernatural, based on oracles, prophecies and omens, I would remind him that there are two ways in which these may be treated. There is the general method, with regard to which there is an endless dispute between the adherents of the Stoics and the Epicureans, as to whether the world is governed by providence. The other is special and is concerned with particular departments of the art of divination, according as they may happen to affect the question at issue.

For the credibility of oracles may be established or destroyed in one way, and that of soothsayers, augurs, diviners and astrologers in another, since the two classes differ entirely in nature. Again the task of establishing or demolishing such evidence as the following will give the orator plenty to do; as for example if certain words have been uttered under

The following method may not merely be used with great effect, but may even be badly missed when it is not employed. You gave me the money. Who counted it out? Where did this occur and from what source did the money come? You accuse me of poisoning. Where did I buy the poison and from whom? What did I pay for it and whom did I employ to administer it? Who was my accomplice? Practically all these points are discussed by Cicero in dealing with the charge of poisoning in the pro Cluentio. [*](cp. IX. 167. ) This concludes my observations upon inartificial proofs. I have stated them as briefly as I could.

The second class of proofs are wholly the work of art and consist of matters specially adapted to produce belief. They are, however, as a rule almost entirely neglected or only very lightly touched on by those who, avoiding arguments as rugged and repulsive things, confine themselves to pleasanter regions and, like those who, as poets tell, were bewitched by tasting a magic herb in the land of the Lotus-eaters or by the song of the Sirens into preferring pleasure to safety, follow the empty semblance of renown and are robbed of that victory which is the aim of eloquence.

And yet those other forms of eloquence, which have a more continuous sweep and flow, are employed with a view to assisting and embellishing the arguments and produce the appearance of super inducing a body upon the sinews, on which the whole case rests; thus if it is asserted

But such rhetorical devices may be employed in connexion with matters about which there is no doubt or at least which we speak of as admitted facts. Nor would I deny that there is some advantage to be gained by pleasing our audience and a great deal by stirring their emotions. Still, all these devices are more effective, when the judge thanks he has gained a full knowledge of the facts of the case, which we can only give him by argument and by the employment of every other known means of proof.

Before, however, I proceed to classify the various species of artificial proof, I must point out that there are certain features common to all kinds of proof. For there is no question which is not concerned either with things or persons, nor can there be any ground for argument save in connexion with matters concerning things or persons, which may be considered either by themselves or with reference to something else;

while there can be no proof except such as is derived from things consequent or things opposite, which must be sought for either in the time preceding, contemporaneous with or subsequent to the alleged fact, nor can any single thing be proved save by reference to something else which must be greater, less than or equal to it.

As regards arguments, they may be found either in the questions raised by the case, which may be considered by themselves quite apart from any connexion with individual

Again there are four forms of proof. First, we may argue that, because one thing is, another thing is not; as It is day and therefore not night. Secondly, we may argue that, because one thing is, another thing is; as The sun is risen, thereit is day. Thirdly, it may be argued that because one thing is not, another thing is; as It is not night, therefore it is day. Finally, it may be argued that, because one thing is not, another thing is not; as He is not a reasoning being, therefore he is not a man. These general remarks will suffice by way of introduction and I will now proceed to details.
