Wherefore, that man appears to me to have acquired an excellent endowment, who is superior to other men in that very thing in which men are superior to beasts. And if this art is acquired not by nature only, not by mere practice, but also by a sort of regular system of education, it appears to me not foreign to our purpose to consider what those men say who have left us some precepts on the subject of the attainment of it.
But, before we begin to speak of oratorical precepts, I think we must say something of the nature of the art itself; of its duty, of its end, of its materials, and of its divisions. For when we have ascertained those points, then each man's mind will, with the more ease and readiness, be able to comprehend the system itself, and the path which leads to excellence in it.
V. There is a certain political science which is made up of many and important particulars. A very great and extensive portion of it is artificial eloquence, which men call rhetoric. For we do not agree with those men who think that the knowledge of political science is in no need of and has no connexion with eloquence; and we most widely disagree with those, on the other hand, who think that all political ability Is comprehended under the skill and power of a rhetorician. On which account we will place this oratorical ability in such a class as to assert that it is a part of political science. But the duty of this faculty appears to be to speak in a manner suitable to persuading men; the end of it is to persuade by language. And there is difference between the duty of this faculty and its end; that with respect to the duty we consider what ought to be done; with respect to the end we consider what is suitable to the duty. Just as we say, that it is the duty of a physician to prescribe for a patient in a way calculated to cure him; and that his end is to cure him by his prescriptions. And so we shall understand what we are to call the duty of an orator, and also what we are to call his end; since we shall call that his duty which he ought to do, and we shall term that his end for the sake of which he is bound to do his duty.
We shall call that the material of the art, on which the whole art, and all that ability which is derived from art, turns. Just as if we were to call diseases and wounds the material of medicine, because it is about them that all medical science is concerned. And in like manner, we call those subjects with which oratorical science and ability is conversant the materials of the art of rhetoric. And these subjects some have considered more numerous, and others less so. For Gorgias the Leontine, who is almost the oldest of all rhetoricians, considered that an orator was able to speak in the most excellent manner of all men on every subject. And when he says this he seems to be supplying an infinite and boundless stock of materials to this art. But Aristotle, who of all men has supplied the greatest number of aids and ornaments to this art, thought that the duty of the rhetorician was conversant with three kinds of subjects; with the demonstrative, and the deliberative, and the judicial.
The demonstrative is that which concerns itself with the praise or blame of some particular individual; the deliberative is that which, having its place in discussion and in political debate, comprises a deliberate statement of one's opinion; the judicial is that which, having its place in judicial proceedings, comprehends the topics of accusation and defence; or of demand and refusal. And, as our own opinion at least inclines, the art and ability of the orator must be understood to be conversant with these tripartite materials. VI For Hermagoras, indeed, appears neither to attend to what he is saying, nor to understand what he is promising, for he divides the materials of an orator into the cause, and the examination. The cause he defines to be a thing which has in itself a controversy of language united with the interposition of certain characters. And that part, we too say, is assigned to the orator, for we give him those three parts which we have already mentioned,—the judicial, the deliberative, and the demonstrative. But the examination he defines to be that thing which has in itself a controversy of language, without the interposition of any particular characters, in this way—"Whether there is anything good besides honesty?"—"Whether the senses may be trusted?"—"What is the shape of the world?"—"What is the size of the sun?" But I imagine that all men can easily see that all such questions are far removed from the business of an orator, for it appears the excess of insanity to attribute those subjects, in which we know that the most sublime genius of philosophers has been exhausted with infinite labour, as if they were inconsiderable matters, to a rhetorician or an orator.
But if Hermagoras himself had had any great acquaintance with these subjects, acquired with long study and training, then it would be supposed that he, from relying on his own knowledge, had laid down some false principles respecting the duty of an orator, and had explained not what his art could effect, but what he himself could do. But as it is, the character of the man is such, that any one would be much more inclined to deny him any knowledge of rhetoric, than to grant him any acquaintance with philosophy. Nor do I say this because the book on the art which he published appears to me to have been written with any particular incorrectness, (for, indeed, he appears to me to have shown very tolerable ingenuity and diligence in arranging topics which he had collected from ancient writings on the subject, and also to have advanced some new theories himself,) but it is the least part of the business of an orator to speak concerning his art, which is what he has done: his business is rather to speak from his art, which is what we all see that this Hermagoras was very little able to do. And so that, indeed, appears to us to be the proper materials of rhetoric, which we have said appeared to be such to Aristotle. VII. And these are the divisions of it, as numerous writers have laid them down: Invention; Arrangement; Elocution; Memory; Delivery. Invention, is the conceiving of topics either true or probable, which may make one's cause appear probable; Arrangement, is the distribution of the topics which have been thus conceived with regular order; Elocution, is the adaptation of suitable words and sentences to the topics so conceived; Memory, is the lasting sense in the mind of the matters and words corresponding to the reception of these topics. Delivery, is a regulating of the voice and body in a manner suitable to the dignity of the subjects spoken of and of the language employed.
Now, that these matters have been briefly defined, we may postpone to another time those considerations by which we may be able to elucidate the character and the duty and the object of this art; for they would require a very long argument, and they have no very intimate connexion with the definition of the art and the delivery of precepts relating to it. But we consider that the man who writes a treatise on the art of rhetoric ought to write about two other subjects also; namely, about the materials of the art, and about its divisions. And it seems, indeed, that we ought to treat of the materials and divisions of this art at the same time. Wherefore, let us first consider what sort of quality invention ought to be, which is the most important of all the divisions, and which applies to every description of cause in which an orator can be engaged.
VIII. Every subject which contains in itself any controversy existing either in language or in disputation, contains a question either about a fact, or about a name, or about a class, or about an action. Therefore, that investigation out of which a cause arises we call a stating of a case. A stating of a case is the first conflict of causes arising from a repulse of an accusation; in this way. "You did so and so;"—"I did not do so;"—or, "it was lawful for me to do so." When there is a dispute as to the fact, since the cause is confirmed by conjectures, it is called a conjectural statement. But when it is a dispute as to a name, because the force of a name is to be defined by words, it is then styled a definitive statement. But when the thing which is sought to be ascertained is what is the character of the matter under consideration, because it is a dispute about violence, and about the character of the affair, it is called a general statement. But when the cause depends on this circumstance, either that that man does not seem to plead who ought to plead, or that he does not plead with that man with whom he ought to plead, or that he does not plead before the proper people, at the proper time, in accordance with the proper law, urging the proper charge, and demanding the infliction of the proper penalty, then it is called a statement by way of demurrer; because the arguing of the case appears to stand in need of a demurrer and also of some alteration. And some one or other of these sorts of statement must of necessity be incidental to every cause. For if there be any one to which it is not incidental, in that there can be no dispute at all; on which account it has no right even to be considered a cause at all.
And a dispute as to fact may be distributed over every sort of time. For as to what has been done, an inquiry can be instituted in this way—"whether Ulysses slew Ajax;" and as to what is being done, in this way—"whether the people of Tregellae are well affected towards the Roman people;" and as to what is going to happen, in this way—"if we leave Carthage uninjured, whether any inconvenience will accrue to the republic."
It is a dispute about a name, when parties are agreed as to the fact, and when the question is by what name that which has been done is to be designated. In which class of dispute it is inevitable on that account that there should be a dispute as to the name; not because the parties are not agreed about the fact, not because the fact is not notorious, but because that which has been done appears in a different light to different people, and on that account one calls it by one name and another by another. Wherefore, in disputes of this kind the matter must be defined by words, and described briefly; as, for instance, if any one has stolen any sacred vessel from a private place, whether he is to be considered a sacrilegious person, or a simple thief. For when that is inquired into, it is necessary to define both points—what is a thief, and what is a sacrilegious person,—and to show by one's own description that the matter which is under discussion ought to be called by a different name from that which the opposite party apply to it. IX. The dispute about kind is, when it is agreed both what has been done, and when there is no question as to the name by which it ought to be designated; and nevertheless there is a question of what importance the matter is, and of what sort it is, and altogether of what character it is; in this way,—whether it be just or unjust; whether it be useful or useless; and as to all other circumstances with reference to which there is any question what is the character of that which has been done, without there being any dispute as to its name. Humagoras assigned four divisions to this sort of dispute: the deliberative, the demonstrative, the judicial, and the one relating to facts. And, as it seems to us, this was no ordinary blunder of his, and one which it is incumbent on us to reprove; though we may do so briefly, lest, if we were to pass it over in silence, we might be thought to have had no good reason for abandoning his guidance; or if we were to dwell too long on this point, we might appear to have interposed a delay and an obstacle to the other precepts which we wish to lay down.
