And in this topic this will be the great point for the accuser, if he is able to show that no one else had any reason for doing so at all. And the thing next in importance will be to show that no one else had such great or sufficient reason for doing so. But if others appear also to have had a motive for doing so, then we must show that they had either no power, or no opportunity, or no inclination to do it. They had no power if it can be said that they did not know it, or were not in the place, or were unable to have accomplished it; they had no opportunity, if it can be proved that any plan, any assistants, any instruments, and all other things which relate to such an action, were wanting to them. They had no inclination, if their disposition can be said to be entirely alien to such conduct, and unimpeachable. Lastly, whatever arguments we allow a man on his trial to use in his defence, the very same the prosecutor will employ in delivering others from blame. But that must be done with brevity, and many arguments must be compressed into one, in order that he may not appear to be accusing the man on his trial for the sake of defending some one else, but to be defending some one else with a view to strengthen his accusation against him.

VIII. And these are for the most part the things which must be done and considered by an accuser. But the advocate for the defence will say, on the other hand, either that there was no motive at all, or, if he admits that there was, he will make light of it, and show that it was a very slight one, or that such conduct does not often proceed from such a motive. And with reference to this topic it will be necessary to point out what is the power and character of that motive, by which the person on his trial is said to have been induced to commit any action; and in doing this it is requisite to adduce instances and examples of similar cases, and the actual nature of such a motive is to be explained as gently as possible, so that the circumstance which is the subject of the discussion may be explained away, and instead of being considered as a cruel and disorderly act, may be represented as something more mild and considerate, and still the speech itself may be adapted to the mind of the hearer, and to a sort of inner feeling, as it were, in his mind.

But the orator will weaken the suspicions arising from the ratiocination, if he shall say either that the advantage intimated had no existence, or a very slight one, or that it was a greater one to others, or that it was no greater advantage to himself than to others, or that it was a greater disadvantage than advantage to himself. So that the magnitude of the advantage which is said to have been desired, was not to be compared with the disadvantage which was really sustained, or with the danger which was incurred. And all those topics will be handled in the same manner in speaking of the avoiding of disadvantage.

But if the prosecutor has said that the man on his trial was pursuing what appeared to him to be an advantage, or was avoiding that which appeared to him to be a disadvantage, even though he was mistaken in that opinion, then the advocate for the defence must show that no one can be so foolish as to be ignorant of the truth in such an affair. And if that be granted, then the other position cannot be granted, that the man ever doubted at all what the case was, but that he, without the least hesitation, considered what was false as false, and what was true as true. But if he doubted, then it was a proof of absolute insanity for a man under the influence of a doubtful hope to incur a certain danger.

But as the accuser when he is seeking to remove the guilt from others must use the topics proper to an advocate for the defence; so the man on his trial must use those topics which have been allotted to an accuser, when he wishes to transfer an accusation from his own shoulders to those of others.

IX. But conjectures will be derived from the person, if those things which have been attributed to persons are diligently considered, all of which we have mentioned in the first book; for sometimes some suspicion arises from the name. But when we say the name, we mean also the surname. For the question is about the particular and peculiar name of a man, as if we were to say that a man is called Caldus because he is a man of a hasty and sudden disposition; or that ignorant Greeks have been deceived by men being called Clodius, or Caecilius, or Marcus.

And we may also derive some suspicious circumstances from nature; for all these questions, whether it is a man or a woman, whether he is of this state or that one, of what ancestors a man is descended, who are his relations, what is his age, what is his disposition, what bodily strength, or figure, or constitution he has, which are all portions of a man's nature, have much influence in leading men to form conjectures.

Many suspicions also are engendered by men's way of life, when the inquiry is how, and by whom, and among whom a man was brought up and educated, and with whom he associates, and what system and habits of domestic life he is devoted to.

Moreover, argumentation often arises from fortune; when we consider whether a man is a slave or a free man, rich or poor, noble or ignoble, prosperous or unfortunate; whether he now is, or has been, or is likely to be a private individual or a magistrate; or, in fact, when any one of those circumstances is sought to be ascertained which are attributable to fortune. But as habit consists in some perfect and consistent formation of mind or body, of which kind are virtue, knowledge, and their contraries; the fact itself, when the whole circumstances are stated, will show whether this topic affords any ground for suspicion. For the consideration of the state of a man's mind is apt to give good grounds for conjecture, as of his affectionate or passionate disposition, or of any annoyance to which he has been exposed; because the power of all such feelings and circumstances is well understood, and what results ensue after any one of them is very easy to be known.

But since study is an assiduous and earnest application of the mind to any particular object with intense desire, that argument which the case itself requires will easily be deduced from it. And again, some suspicion will be able to be inferred from the intention; for intention is a deliberate determination of doing or not doing something. And after this it will be easy to see with respect to facts, and events, and speeches, which are divided into three separate times, whether they contribute anything to confirming the conjectures already formed in the way of suspicion.
