The next topic is one which is derived from contraries. But the genera of contraries are several. One is of such things as differ in the same kind; as wisdom and jolly. But those things are said to be in the same kind, which, when they are proposed, are immediately met by certain contraries, as if placed opposite to them: as slowness is contrary to rapidity, and not weakness. From which contraries such arguments as these are deduced:--"If we avoid folly, let us pursue wisdom; and if we avoid wickedness, let us pursue goodness." These things, as they are contrary qualities in the same cla.s.s, are called opposites. For there are other contraries, which we may call in Latin, _privantia_, and which the Greeks call [Greek: _steraetika_]. For the preposition _in_ deprives the word of that force which it would have if _in_ were not prefixed; as, "dignity, indignity--humanity, inhumanity," and other words of the same kind, the manner of dealing with which is the same as that of dealing with other kinds which I have called opposites. For there are also other kinds or contraries; as those which are compared to something or other; as, "twofold and simple; many and few; long and short; greater and less." There are also those very contrary things which are called negatives, which the Greeks call [Greek: _steraetika_]: as, "If this is the case, that is not." For what need is there for an instance? only let it be understood that in seeking for an argument it is not every contrary which is suitable to be opposed to another.

XII. But I gave a little while ago an instance drawn from adjuncts; showing that many things are added as accessories, which ought to be admitted, if we decided that possession ought to be given by the praetor's edict, in compliance with the will which that person made who had no right whatever to make a will. But this topic has more influence in conjectural causes, which are frequent in courts, of justice, when we are inquiring either what is, or what has been, or what is likely to be, or what possibly may happen. And the form of the topic itself is as follows. But this topic reminds us to inquire what happened before the transaction of which we are speaking, or at the same time with the transaction, or after the transaction. "This has nothing to do with the law, you had better apply to Cicero," our friend Gallus used to say, if any one brought him any cause which required an inquiry into matters of fact. But you will prefer that no topic of the art which I have begun to treat of should be omitted by me, lest if you should think that nothing was to be written here except what had reference to yourself, you should seem to be too selfish. This then is for the most part an oratorical topic; not only not much suited to lawyers, but not even to philosophers. For the circ.u.mstances which happened before the matter in question are inquired into, such as any preparation, any conferences, any place, any prearranged convivial meeting. And the circ.u.mstances which happened at the same time with the matter in question, are the noise of footfalls, the noise of men, the shadow of a body, or anything of that sort. The circ.u.mstances subsequent to the matter in question are, blushing, paleness, trepidation, or any other tokens of agitation or consciousness; and besides these, any such fact as a fire extinguished, a b.l.o.o.d.y sword, or any circ.u.mstance which can excite a suspicion of such an act.

XIII. The next topic is one peculiar to dialecticians; derived from consequents, and antecedents, and inconsistencies; and this one is very different from that drawn from differences. For adjuncts, of which we were speaking just now, do not always exist, but consequents do invariably. I call those things consequents which follow an action of necessity. And the same rule holds as to antecedents and inconsistencies; for whatever precedes each thing, that of necessity coheres with that theme; and whatever is inconsistent with it is of such a nature that it can never cohere with it. As then this topic is distributed in three divisions, into consequence, antecession, and inconsistency, there is one single topic to help us find the argument, but a threefold way of dealing with it. For what difference does it make, when you have once a.s.sumed that the ready money is due to the woman to whom all the money has been bequeathed, whether you conclude your argument in this way:--"If coined money is money, it has been bequeathed to the woman; but coined money is money; therefore it has been bequeathed to her;"--or in this way: "If ready money has not been bequeathed to her, then ready money is not money; but ready money is money; therefore it has been bequeathed to her;"--or in this way: "The cases of money not having been bequeathed, and of ready money not having been bequeathed, are identical; but money was bequeathed to her; therefore ready money was bequeathed to her?" But the dialecticians call that conclusion of the argument in which, when you have first made an a.s.sumption, that which is connected with it follows as a consequence of the a.s.sumption, the first mood of the conclusion; and when, because you have denied the consequence, it follows that that also to which it was a consequence must be denied also, that is the second mood. But when you deny some things in combination, (and then another negation is added to them,) and from these things you a.s.sume something, so that what remains is also done away with, that is called the third mood of the conclusion. From this are derived those results of the rhetoricians drawn from contraries, which they call enthymemes. Not that every sentence may not be legitimately called an enthymeme; but, as Homer on account of his preeminence has appropriated the general name of poet to himself as his own among all the Greeks; so, though every sentence is an enthymeme, still, because that which is made up of contraries appears the most acute argument of the kind, that alone has possessed itself of the general name as its own peculiar distinction. Its kinds are these:--"Can you fear this man, and not fear that one?"--"You condemn this woman, against whom you bring no accusation; and do you say that this other one deserves punishment, whom you believe to deserve reward?"--"That which you do know is no good; that which you do not know is a great hindrance to you."

XIV. This kind of disputing is very closely connected with the mode of discussion adopted by you lawyers in reply, and still more closely with that adopted by philosophers, as they share with the orators in the employment of that general conclusion which is drawn from inconsistent sentences, which is called by dialecticians the third mood, and by rhetoricians an enthymeme. There are many other moods used by the rhetoricians, which consist of disjunctive propositions:--"Either this or that is the case; but this is the case; then that is not the case." And again:--"Either this or that is the case; but this is not the case; then that is the case." And these conclusions are valid, because in a disjunctive proposition only one alternative can be true. And from those conclusions which I have mentioned above, the former is called by the dialecticians the fourth mood, and the latter the fifth. Then they add a negation of conjunctive propositions; as, "It is not both this and that; but it is this; therefore it is not that." This is the sixth mood. The seventh is, "It is not both this and that; but it is not this; therefore it is that." From these moods innumerable conclusions are derived, in which nearly the whole science of dialectics consists. But even those which I have now explained are not necessary for this present discussion.

XV. The next topic is drawn from efficient circ.u.mstances which are called causes; and the next from the results produced by these efficient causes. I have already given instances of these, as of the other topics, and those too drawn from civil law; but these have a wider application.

There are then two kinds of causes; one which of its own force to a certainty produces that effect which is subordinate to it; as, "Fire burns;" the other is that which has no nature able to produce the effect in question, though still that effect cannot be produced without it; as, if any one were to say, that "bra.s.s was the cause of a statue; because a statue cannot be made without it." Now of this kind of causes which are indispensable to a thing being done, some are quiet some pa.s.sive, some, as it were, senseless; as, place, time, materials, tools, and other things of the same sort. But some exhibit a sort of preparatory process towards the production of the effect spoken of; and some of themselves do contribute some aid to it; although it is not indispensable; as meeting may have supplied the cause to love; love to crime. From this description of causes depending on one another in infinite series, is derived the doctrine of fate insisted on by the Stoics. And as I have thus divided the genera of causes, without which nothing can be effected, so also the genera of the efficient causes can be divided in the same manner. For there are some causes which manifestly produce the effect, without any a.s.sistance from any quarter; others which require external aid; as for instance, wisdom alone by herself makes men wise; but whether she is able alone to make men happy is a question.

XVI. Wherefore, when any cause efficient as to some particular end has inevitably presented itself in a discussion, it is allowable without any hesitation to conclude that what that cause must inevitably effect is effected. But when the cause is of such a nature that it does not inevitably effect the result, then the conclusion which follows is not inevitable And that description of causes which has an inevitable effect does not usually engender mistakes; but this description, without which a thing cannot take place, does often cause perplexity.

For it does not follow, because sons cannot exist without parents, that there was therefore any unavoidable cause in the parents to have children. This, therefore, without which an effect cannot be produced, must be carefully separated from that by which it is certainly produced. For that is like--

"Would that the lofty pine on Pelion's brow Had never fall'n beneath the woodman's axe!"

For if the beam of fir had never fallen to the ground, that Argo would not have been built; and yet there was not in the beams any unavoidably efficient power. But when

"The fork'd and fiery bolt of Jove"

was hurled at Ajax's vessel, that ship was then inevitably burnt.

And again, there is a difference between causes, because some are such that without any particular eagerness of mind, without any expressed desire or opinion, they effect what is, as it were, their own work; as for instance, "that everything must die which has been born." But other results are effected either by some desire or agitation of mind, or by habit, or nature, or art, or chance. By desire, as in your case, when you read this book; by agitation, as in the case of any one who fears the ultimate issue of the present crisis; by habit, as in the case of a man who gets easily and rapidly in a pa.s.sion; by nature, as vice increases every day; by art, as in the case of a man who paints well; by chance, as in the case of a man who has a prosperous voyage.

None of these things are without some cause, and yet none of them are wholly owing to any single cause. But causes of this kind are not necessary ones.

XVII. But in some of these causes there is a uniform operation, and in others there is not. In nature and in art there is uniformity; but in the others there is none. But still of those causes which are not uniform, some are evident, others are concealed. Those are evident which touch the desire or judgment of the mind; those are concealed which are subject to fortune: for as nothing is done without some cause, this very obscure cause, which works in a concealed manner, is the issue of fortune. Again, these results which are produced are partly unintended, partly intentional. Those are unintended which are produced by necessity; those are intentional which are produced by design. But those results which are produced by fortune are either unintended or intentional. For to shoot an arrow is an act of intention; to hit a man whom you did not mean to hit is the result of fortune. And this is the topic which you use like a battering-ram in your forensic pleadings; if a weapon has flown from the man's hand rather than been thrown by him. Also agitation of mind may be divided into absence of knowledge and absence of intention. And although they are to a certain extent voluntary, (for they are diverted from their course by reproof or by admonition,) still they are liable to such emotions that even those acts of theirs which are intentional sometimes seem either unavoidable, or at all events unintentional.

The whole topic of these causes then being now fully explained, from their differences there is derived a great abundance of arguments in all the important discussions of orators and philosophers. And in the cases which you lawyers argue, if there is not so plentiful a stock, what there are, are perhaps more subtle and shrewd. For in private actions the decisions in the most important cases appear to me to depend a great deal on the acuteness of the lawyers. For they are constantly present, and are taken into counsel; and they supply weapons to able advocates whenever they have recourse to their professional wisdom.

In all those judicial proceedings then, in which the words "according to good faith" are added, or even those words, "as ought to be done by one good man to another;" and above all, in all cases of arbitration respecting matrimonial rights, in which the words "juster and better"

occur, the lawyers ought to be always ready. For they know what "dishonest fraud," or "good faith," or "just," or "good" mean. They are acquainted with the law between partners; they know what the man who has the management of the affairs of another is bound to do with respect to him whose affairs he manages; they have laid down rules to show what the man who has committed a charge to another, and what he who has had it committed to him, ought to do; what a husband ought to confer on his wife, and a wife on her husband. It will, therefore, when they have by diligence arrived at a proper understanding of the topics from which the necessary arguments are derived, be in the power not only of orators and philosophers, but of lawyers also, to discuss with abundance of argument all the questions which can arise for their consideration.

XVIII. Conjoined to this topic of causes is that topic which is supplied by causes. For as cause indicates effect, so what has been effected points out what the efficient cause has been. This topic ordinarily supplies to orators and poets, and often to philosophers also, that is to say, to those who have an elegant and argumentative and rich style of eloquence, a wonderful store of arguments, when they predict what will result from each circ.u.mstance. For the knowledge of causes produces a knowledge of effects.

The remaining topic is that of comparison, the genus and instances of which have been already explained, as they have in the case of the other topics. At present we must explain the manner of dealing with this one. Those things then are compared which are greater than one another, or less than one another, or equal to one another. In which these points are regarded; number, appearance, power, and some particular relation to some particular thing.

Things will be compared in number thus: so that more advantages may be preferred to fewer; fewer evils to more; more lasting advantages to those which are more short-lived; those which have an extensive application to those the effect of which is narrowed: those from which still further advantages may be derived, and those which many people may imitate and reproduce.

Things again will be compared with reference to their appearance, so that those things may be preferred which are to be desired for their own sake, to those which are only sought for the sake of something else: and so that innate and inherent advantages may be preferred to acquired and advent.i.tious ones; complete good to mixed good; pleasant things to things less pleasant; honourable things to such as are merely useful; easy things to difficult ones; necessary to unnecessary things; one's own advantage to that of others; rare things to common ones; desirable things to those which you can easily do without; things complete to things which are only begun; wholes to parts; things proceeding on reason to things void of reason; voluntary to necessary things; animate to inanimate things; things natural to things not natural; things skilfully produced by art to things with which art has no connexion.

But power in a comparison is perceived in this way: an efficient cause is more important than one which effects nothing; those causes which can act by themselves are superior to those which stand in need of the aid of others; those which are in our power are preferable to those which are in the power of another; lasting causes surpa.s.s those which are uncertain; things of which no one can deprive us are better than things which can be easily taken away.

But the way in which people or things are disposed towards some things is of this sort: the interests of the chief citizens are more important than those of the rest: and also, those things which are more agreeable, which are approved of by more people, or which are praised by the most virtuous men, are preferable. And as in a comparison these things are the better, so those which are contrary to them are the worse.

But the comparison between things like or equal to each other has no elation or submission; for it is on equal terms: but there are many things which are compared on account of their very equality; which are usually concluded in this manner: "If to a.s.sist one's fellow-citizens with counsel and personal aid deserves equal praise, those men who act as counsellors ought to enjoy an equal glory with those who are the actual defenders of a state." But the first premiss is certainly the case; therefore so must the consequent be.

Every rule necessary for the discovery of arguments is now concluded; so that as you have proceeded from definition, from part.i.tion, from observation, from words connected with one another, from genus, from species, from similarity, from difference, from contraries, from accessories, from consequents, from antecedents, from things inconsistent with one another, from causes, from effects, from a comparison with greater, or lesser, or equal things,--there is no topic of argument whatever remaining to be discovered.

XIX. But since we originally divided the inquiry in such a way that we said that other topics also were contained in the very matter which was the subject of inquiry; (but of those we have spoken at sufficient length:) that others were derived from external subjects; and of these we will say a little; although those things have no relation whatever to your discussions. But still we may as well make the thing complete, since we have begun it. Nor are you a man who take no delight in anything except civil law; and since this treatise is dedicated to you, though not so exclusively but that it will also come into the hands of other people, we must take pains to be as serviceable as possible to those men who are addicted to laudable pursuits.

This sort of argumentation then which is said not to be founded on art, depends on testimony. But we call everything testimony which is deduced from any external circ.u.mstances for the purpose of implanting belief. Now it is not every one who is of sufficient weight to give valid testimony; for authority is requisite to make us believe things.

But it is either a man's natural character or his age which invests him with authority. The authority derived from a man's natural character depends chiefly on his virtue; but on his age there are many things which confer authority; genius, power, fortune, skill, experience, necessity, and sometimes even a concourse of accidental circ.u.mstances. For men think able and opulent men, and men who have been esteemed during a long period of their lives, worthy of being believed Perhaps they are not always right; but still it is not easy to change the sentiments of the common people; and both those who form judgments and those who adopt vague opinions shape everything with reference to them. For those men who are eminent for those qualities which I have mentioned, seem to be eminent for virtue itself. But in the other circ.u.mstances also which I have just enumerated, although there is in them no appearance of virtue, still sometimes belief is confirmed by them, if either any skill is displayed,--for the influence of knowledge in inspiring belief is very great; or any experience--for people are apt to believe those who are men of experience.

XX. Necessity also engenders belief, which sways both bodies and minds. For what men say when worn out with tortures, and stripes, and fire, appears to be uttered by truth itself. And those statements which proceed from agitation of mind, such as pain, cupidity, pa.s.sion, and fear, because those feelings have the force of necessity, bring authority and belief. And of this kind are those circ.u.mstances from which at times the truth is discovered; childhood, sleep, ignorance, drunkenness, insanity. For children have often indicated something, though ignorant to what it related; and many things have often been discovered by sleep, and wine, and insanity. Many men also have without knowing it fallen into great difficulties, as lately happened to Stalenus; who said things in the hearing of certain excellent men, though a wall was between them, which, when they were revealed and brought before a judicial tribunal, were thought so wicked that he was rightly convicted of a capital offence. And we have heard something similar concerning Pausanias the Lacedaemonian.

But the concourse of fortuitous events is often of this kind; when anything has happened by chance to interrupt, when anything was being done or said which it was desirable should not have been done or said.

Of this kind is that mult.i.tude of suspicions of treason which were heaped upon Palamedes. And circ.u.mstances of this kind are sometimes scarcely able to be refuted by truth itself. Of this kind too is ordinary report among the common people; which is as it were the testimony of the mult.i.tude.

But those things which create belief on account of the virtue of the witness are of a two-fold kind; one of which is valid on account of nature, the other by industry. For the virtue of the G.o.ds is eminent by nature; but that of men, because of their industry.

Testimonies of this kind are nearly divine, first of all, that of oration, (for oracles were so called from that very same word, as there is in them the oration of the G.o.ds;) then that of things in which there are, as it were, many divine works; first of all, the word itself, and its whole order and ornaments; then the airy flights and songs of birds; then the sound and heat of that same air; and the numerous prodigies of divers kinds seen on the earth; and also, the power of foreseeing the future by means of the entrails of victims: many things, too, which are shown to the living by those who are asleep: from all which topics the testimonies of the G.o.ds are at times adduced so as to create belief.

In the case of a man, the opinion of his virtue is of the greatest weight. For opinion goes to this extent, that those men have virtue, not only who do really possess it, but those also who appear to possess it. Therefore, those men whom they see endowed with genius and diligence and learning, and whose life they see is consistent and approved of, like Cato and Laelius, and Scipio, and many others, they consider such men as they themselves would wish to be. And not only do they think them such who enjoy honours conferred on them by the people, and who busy themselves with affairs of state, but also those who are orators, and philosophers, and poets, and historians; from whose sayings and writings authority is often sought for to establish belief.

XXI. Having thus explained all the topics serviceable for arguing, the first thing to be understood is, that there is no discussion whatever to which some topic or other is not applicable; and on the other hand, that it is not every topic which is applicable to every discussion; but that different topics are suited to different subjects.

There are two kinds of inquiry: one, infinite; the other, definite.

The definite one is that which the Greeks call [Greek: hupothesis], and we, a cause; the infinite one, that which they call [Greek: thesis], and which we may properly term a proposition.

A cause is determined by certain persons, places, times, actions, and things, either all or most of them; but a proposition is declared in some one of those things, or in several of them, and those not the most important: therefore, a proposition is a part of a cause. But the whole inquiry is about some particular one of those things in which causes are contained; whether it be one, or many, or sometimes all.

But of inquiries, concerning whatever thing they are, there two kinds; one theoretical, the other practical. Theoretical inquiries are those of which the proposed aim is science; as, 'If it is inquired whether right proceeds from nature, or from some covenant, as it were, and bargain between men. But the following are instances of practical inquiry: "Whether it is the part of a wise man to meddle with statesmanship." The inquiries into theoretical matters are threefold; as what is inquired is, whether a thing exists, or what it is, or what its character is. The first of these queries is explained by conjecture; the second, by definition; the third, by distinctions of right and wrong.

The method of conjecture is distributed into four parts; one of which is, when the inquiry is whether something exists; a second, when the question is, whence it has originated; a third, when one seeks to know what cause produced it; the fourth is that in which the alterations to which the subject is liable are examined: "Whether it exists or not; whether there is anything honourable, anything intrinsically and really just; or whether these things only exist in opinion." But the inquiry whence it has originated, is when an inquiry is such as this, "Whether virtue is implanted by nature, or whether it can be engendered by instruction." But the efficient cause is like this, as when an inquiry is, "By what means eloquence is produced." Concerning the alterations of anything, in this manner: "Whether eloquence can by any alteration be converted into a want of eloquence."

XXII. But when the question is what a thing is; the notion is to be explained, and the property, and the division, and the part.i.tion. For these things are all attributed to definition. Description also is added, which the Greeks call [Greek: charaktaer]. A notion is inquired into in this way: "Whether that is just which is useful to that person who is the more powerful." Property, in this way: "Whether melancholy is incidental to man alone, or whether beasts also are liable to it."

Division, and also part.i.tion, in this manner: "Whether there are three descriptions of good things." Description, like this: "What sort of person a miser is; what sort of person a flatterer;" and other things of that sort, by which the nature and life of a man are described.

But when the inquiry is what the character of something is, the inquiry is conducted either simply, or by way of comparison.

Simply, in this way: "Whether glory is to be sought for." By way of comparison, in this way: "Whether glory is to be preferred to riches."

Of simple inquiries there are three kinds; about seeking for or avoiding anything, about the right and the wrong; about what is honourable and what is discreditable. But of inquiries by way of comparison there are two; one of the thing itself and something else; one of something greater and something else. Of seeking for and avoiding a thing, in this way: "Whether riches are to be sought for: whether poverty is to be avoided." Concerning right and wrong: "Whether it is right to revenge oneself, whoever the person may be from whom one has received an injury." Concerning what is honourable and what is discreditable: "Whether it is honourable to die for one's country." But of the other kind of inquiry, which has been stated to be twofold, one is about the thing in question and something else; as if it were asked, "What is the difference between a friend and a flatterer, between a king and a tyrant?" The other is between something greater and something less; as if it were asked, "Whether eloquence is of more consequence than the knowledge of civil law." And this is enough about theoretical inquiries.

It remains to speak of practical ones; of which there are two kinds: one relating to one's duty, the other to engendering, or calming, or utterly removing any affection of the mind. Relating to duty thus: as when the question is, "Whether children ought to be bad." Relating to influencing the mind, when exhortations are delivered to men to defend the republic, or when they are encouraged to seek glory and praise: of which kind of addresses are complaints, and encouragements, and tearful commiseration; and again, speeches extinguishing anger, or at other times removing fear, or repressing the exultation of joy, or effacing melancholy. As these different divisions belong to general inquiries, they are also transferable to causes.

XXIII. But the next thing to be inquired is, what topics are adapted to each kind of inquiry; for all those which we have already mentioned are suitable to most kinds; but still, different topics, as I have said before, are better suited to different investigations. Those arguments are the most suitable to conjectural discussion which can be deduced from causes, from effects, or from dependent circ.u.mstances.

But when we have need of definition, then we must have recourse to the principles and science of defining. And akin to this is that other argument also which we said was employed with respect to the subject in question and something else; and that is a species of definition.

For if the question is, "Whether pertinacity and perseverance are the same thing," it must be decided by definitions. And the topics which are incidental to a discussion of this kind are those drawn from consequents, or antecedents, or inconsistencies, with the addition also of those two topics which are deduced from causes and effects.

For if such and such a thing is a consequence of this, but not a consequence of that; or if such and such a thing is a necessary antecedent to this, but not to that; or if it is inconsistent with this, but not with that; or if one thing is the cause of this, and another the cause of that; or if this is effected by one thing, and that by another thing; from any one of these topics it may be discovered whether the thing which is the subject of discussion is the same thing or something else.

With respect to the third kind of inquiry, in which the question is what the character of the matter in question is, those things are incidental to the comparison which were enumerated just now under the topic of comparison. But in that kind of inquiry where the question is about what is to be sought for or avoided, those arguments are employed which refer to advantages or disadvantages, whether affecting the mind or body, or being external. And again, when the inquiry is not what is honourable or discreditable, all our argument must be addressed to the good or bad qualities of the mind.

But when right and wrong are being discussed, all the topics of equity are collected. These are divided in a two-fold manner, as to whether they are such by nature or owing to inst.i.tutions. Nature has two parts to perform, to defend itself, and to indicate right. But the agreements which establish equity are of a threefold character: one part is that which rests on laws; one depends on convenience; the third is founded on and established by antiquity of custom. And again, equity itself is said to be of a threefold nature: one division of it having reference to the G.o.ds above; another, to the shades below; a third, to mankind. The first is called piety; the second, sanct.i.ty; the third, justice or equity.

XXIV. I have said enough about propositions. There are now a few things which require to be said about causes. For they have many things in common with propositions.

There are then three kinds of causes; having for their respective objects, judgment, deliberation, and panegyric. And the object of each points out what topics we ought to employ in each. For the object of judicial judgment is right; from which also it derives its name. And the divisions of right were explained when we explained the divisions of equity. The object of deliberation is utility; of which the divisions have also been already explained when we were treating of things to be desired. The object of panegyric is honour; concerning which also we have already spoken.
