Demosthenes, indeed, whose bust of brass I lately saw between the images of yourself and your ancestors, (a proof, I suppose, of your fondness for him,) when I was with you at your Tusculan villa, does not yield at all to Lysias in acuteness, nor in shrewdness and cleverness to Hyperides, nor in gentleness or brilliancy of language to Aeschines. Many of his orations are very closely argued, as that against Leptines; many are wholly dignified, as some of the Philippics; many are of varied style, as those against Aeschines, the one about the false embassy, and the one also, against the same Aeschines in the cause of Ctesiphon. As often as he pleases he adopts the middle style, and, departing from his dignified tone, he indulges in that lower one. But when he raises the greatest outcry on the part of his hearers, and makes the greatest impression by his speech, is when he employs the topics of dignity.
However, let us leave Demosthenes for awhile, since it is a class that we are inquiring about, and not an individual. Let us rather explain the effect and nature of the thing; that is, of Eloquence. And let us recollect what we have just said, that we are not going to say anything for the sake of giving rules; but that we are going to speak so as to be thought people expressing an opinion rather than teaching. Though we often do advance further, because we see that you are not the only person who will read this; you who, in fact, know all this much better than we ourselves who appear to be teaching you; but it is quite certain that this book will be extensively known, if not from the recommendation which its being my work will give it, at all events, because of its appearing under the sanction of your name, by being dedicated to you.
XXXII. I think, then, that it belongs to a perfectly eloquent man, not only to have the ability, which is his peculiar province, of speaking copiously and with the assertion of large principles, but also to possess its neighbouring and contiguous science of dialectics: although an oration appears one thing and a discussion another; nor is talking the same thing as speaking; though each belongs to discussing. Let then the system of discussing and talking belong to the logicians; but let the province of the orators be to speak and to embellish their speeches. Zeno, that great man, who founded the school of the Stoics, was in the habit of showing with his hand what was the difference between these arts; for when he had compressed his fingers and made a fist, he said that dialectics were like that; but when he had opened his fingers and expanded his hand, he said that eloquence was like his open palm. And even before him Aristotle, in the beginning of his Rhetoric, said, that the art of eloquence in one portion of it corresponded to dialectics; so that they differ from one another in this, that the system of speaking is more wide, that of talking more contracted. I wish, then, that this consummate orator should be acquainted with the entire system of talking, as far as it can be applied to speaking; and that (as indeed you, who have a thorough acquaintance with these arts, are well aware) has a twofold method of teaching. For Aristotle himself has given many rules for arguing: and those who followed him, and who are called dialecticians, have delivered many very difficult rules. Therefore I think, that the man who is tempted by the glory of eloquence, is not utterly ignorant of those things; but that he has been brought up either in that old school, or in the school of Chrysippus. Let him first acquaint himself with the meaning and nature and classes of words, both single and combined; then let him learn in how many ways each word is used; then how it is decided, whether a thing is false or true; then what results from each proposition; then to what argument each result is a consequence, and to what it is contrary; and, as many things are stated in an ambiguous manner, he must also learn how each of them ought to be distinguished and explained. This is what must be acquired by an orator; for those things are constantly occurring; but, because they are in their own nature less attractive, it is desirable to employ some brilliancy of eloquence in explaining them.
XXXIII. And since in all things which are taught in any regular method and system, it is first of all necessary to settle what each thing is, (unless it is agreed by those who are discussing the point, what the thing really is which is being discussed; nor otherwise is it possible to discuss anything properly, or ever to get to the end of the discussion,) we must often have recourse to words to explain our meaning about each thing; and we must facilitate the understanding of an involved and obscure matter by definition; since definition is a kind of speech which points out in the most concise possible manner what that is which is the subject of discussion. Then, as you know, when the genus of each thing has been explained, we must consider what are the figures or divisions of that genus, so that our whole speech may be arranged with reference to them.
This faculty, then, will exist in the eloquent man whom we are endeavouring to describe, so that he shall be able to define a thing; and shall do it in the same close and narrow terms which are commonly employed in those very learned discussions; but he shall be more explanatory and more copious, and he shall adopt his definition more to the ordinary judgment and usual intelligence of mankind. And again, when circumstances require it, he shall divide and arrange the whole genus into certain species, so that none shall be omitted and none be superfluous. But when he shall do this, or how, is nothing to the present question; since, as I have said before, I am here only expressing an opinion, not giving a lesson.
Nor, indeed, must he be learned only in dialectics, but he must have all the topics of philosophy familiar to him and at his fingers' ends. For nothing respecting religion, or death, or affection, or love for one's country, or good fortune, or bad fortune, or virtues, or vices, or duty, or pain, or pleasure, or the different motions of the mind, or mistakes, all which topics frequently occur in causes, but are treated usually in a very meagre manner, can be discussed and explained in a dignified and lofty and copious manner without that knowledge which I have mentioned.
XXXIV. I am speaking at present concerning the subject matter of a speech, not about the kind of speaking requisite. For I would rather that an orator should first have a subject to speak of worthy of learned ears, before he considers in what words or in what manner he is to speak of everything; and, in order to make him grander, and in some sense loftier (as I have said above about Pericles,) I should wish him not to be utterly ignorant of physical science; and then, when he descends again from heavenly matters to human affairs, he will have all his words and sentiments of a more sublime and magnificent character: and while he is acquainted with those divine laws, I do not wish him to be ignorant of those of men. He must be a master of civil law, which forensic debates are in daily need of. For what is more shameful than for a man to undertake the conduct of legal and civil disputes, while ignorant of the statutes and of civil law? He must be acquainted also with the history of past ages and the chronology of old time, especially, indeed, as far as our own state is concerned; but also he must know the history of despotic governments and of illustrious monarchs; and that toil is made easier for us by the labours of our friend Atticus, who has preserved and made known the history of former times in such a way as to pass over nothing worth knowing, and yet to comprise the annals of seven hundred years in one book. For not to know what happened before one was born, is to be a boy all one's life. For what is the life of a man unless by a recollection of bygone transactions it is united to the times of his predecessors? But the mention of antiquity and the citation of examples give authority and credit to a speech, combined with the greatest pleasure to the hearers.
XXXV. Let him, therefore, come to his causes prepared in this kind of way; and he will in the first place be acquainted with the different kinds of causes. For he will be thoroughly aware that nothing can be doubted except when either the fact or the language gives rise to controversy. But the fact is doubted as to its truth, or its propriety, or its name. Words give rise to dispute if they are ambiguous or inconsistent. For it ever appears to be the case, that one thing is meant and another expressed; then that is one kind of ambiguity which arises from the words which are employed; and in this we see that two things are meant, which is a property of all ambiguous sentences.
As there are not many different kinds of causes, so also the rules for arguments to be used in them are few. Two kinds of topics are given from which they may be derived; one from the circumstances themselves, the others assumed. The handling, then, of the matters themselves makes the speech better; for the matters themselves are usually easy to be acquainted with. For what remains afterwards, which at least belongs to art, except to begin the speech in such a manner that the hearer may be conciliated, or have his attention roused, or may be made eager to learn? then after that to explain with brevity, and probability, and clearness, so that it may be understood what is the question under discussion; to establish his own arguments; to overturn those of the opposite party; and to do all that, not in an irregular and confused manner, but with separate arguments, concluded in such a manner, that everything may be established which is a natural consequence of those principles which are assumed for the confirmation of each point: and after everything else is done, then to wind up with a peroration which shall inflame or cool the hearers, as the case may require.
Now, how the consummate orator handles each separate division of his subject, it is hard to explain in this place; nor, indeed, are they handled at all times in the same manner. But since I am not seeking a pupil to teach, but a model to approve of, I will begin by praising the man who sees what is becoming. For this is above all others the wisdom which the eloquent man wants, namely—to be the regulator of times and persons. For I do not think that a man ought to speak in the same manner at all times, or before all people, or against every one, or in defence of every one, or to every one.
