Institutio Oratoria

For my own part, and I have authority to support me, I hold that the material of rhetoric is composed of everything that may be placed before it as a subject for speech. Plato, if I read him aright, makes Socrates [*](Gorg. 449 E. ) say to Gorgias that its material is to be

Cicero also in a passage [*](de Inv. i. 5. ) of one of his works, states that the material of rhetoric is composed of the things which are brought before it, but makes certain restrictions as to the nature of these things. In another passage, [*](de Or. I. vi. 21. I will not demand omniscience from an orator, although etc. ) however, he expresses his opinion that the orator has to speak about all kinds of things; I will quote his actual words:

although the very meaning of the name of orator and the fact that he professes to speak well seem to imply a promise and undertaking that the orator will speak with elegance and fullness on any subject that may be put before him.

And in another passage [*](ib. iii. xiv. 54. ) he says,

It is the duty of the true orator to seek out, hear, read, discuss, handle and ponder everything that befalls in the life of man, since it is with this that the orator is concerned and this that forms the material with which he has to deal.

But this material, as we call it, that is to say the things brought before it, has been criticised by some, at times on the ground that it is limitless, and sometimes on the ground that it is not peculiar to oratory, which they have therefore dubbed a discursive art, because all is grist that comes to its mill.

I have no serious quarrel with these critics, for they acknowledge that rhetoric is concerned with every kind of material, though they deny that it has any peculiar material just because of that material's multiplicity. But in spite of this multiplicity, rhetoric is not unlimited in scope, and there are other minor

As for sculpture, its activity extends to wood, ivory, marble, glass and precious stones in addition to the materials already mentioned.

And things which form the material for other artists, do not for that reason cease forthwith to be material for rhetoric. For if I ask what is the material of the sculptor, I shall be told bronze; and if I ask what is the material of the maker of vessels (I refer to the craft styled χαλκευτική by the Greeks), the answer will again be bronze: and yet there is all the difference in the world between vessels and statues.

Similarly medicine will not cease to be an art, because, like the art of the gymnast, it prescribes rubbing with oil and exercise, or because it deals with diet like the art of cookery.

Again, the objection that to discourse of what is good, expedient or just is the duty of philosophy presents no difficulty. For when such critics speak of a philosopher, they mean a good man. Why then should I feel surprised to find that the orator whom I identify with the good man deals with the same material?

There is all the less reason, since I have already shown in the first book [*]( Pref. § 10 sqq. ) that philosophers only usurped this department of knowledge after it had been abandoned by the orators: it was always the peculiar property of rhetoric and the philosophers are really trespassers. Finally, since the discussion of whatever is brought before it is the task of dialectic, which is really a concise form of oratory, why should not this task be regarded as also being the appropriate material for continuous oratory?

Well then, if an orator has to speak on every subject, he must be the master of all the arts.

In my opinion no one can be an absolutely perfect orator unless he has acquired a knowledge of all important subjects and arts.

For he cannot have a knowledge of all causes, and yet he should be able to speak on all. On what then will he speak? On those which he has studied. Similarly as regards the arts, he will study those concerning which he has to speak, as occasion may demand, and will speak on those which he has studied.

What then?—I am asked—will not a builder speak better on the subject of building and a musician on music? Certainly, if the orator does not know what is the question at issue. Even an illiterate peasant who is a party to a suit will speak better on behalf of his case than an orator who does not know what the subject in dispute may be. But on the other hand if the orator receive instruction from the builder or the musician, he will put forward what he has thus learned better than either, just as he will plead a case better than his client, once he has been instructed in it.

The builder and the musician will, however, speak on the subject of their respective arts, if there should be any technical point which requires to be established. Neither will be an orator, but he will perform his task like an orator, just as when an untrained person binds up a

Is it suggested that such topics never crop up in panegyric, deliberative or forensic oratory? When the question of the construction of a port at Ostia came up for discussion, had not the orator to state his views? And yet it was a subject requiring the technical knowledge of the architect.

Does not the orator discuss the question whether livid spots and swellings on the body are symptomatic of ill-health or poison? And yet that is a question for the qualified physician. Will he not deal with measurements and figures? And yet we must admit that they form part of mathematics. For my part I hold that practically all subjects are under certain circumstances liable to come up for treatment by the orator. If the circumstances do not occur, the subjects will not concern him.

We were therefore right in asserting that the material of rhetoric is composed of everything that comes before the orator for treatment, an assertion which is confirmed by the practice of everyday speech. For when we have been given a subject on which to speak, we often preface our remarks by calling attention to the fact that the matter has been laid before us.

Gorgias indeed felt so strongly that it was the orator's duty to speak on every subject, that he used to allow those who attended his lectures to ask him questions on any subject they pleased. Hermagoras also asserted that the material of oratory lay in the cause and the questions it involved, thereby including every subject that can be brought before it.

If he denies that general questions [*](See III V. 12–16.) are the concern of oratory, he disagrees with me: but if they do concern rhetoric, that

Aristotle [*](Rhet. I. iii. 3. ) himself also by his tripartite division of oratory, into forensic, deliberative and demonstrative, practically brought everything into the orator's domain, since there is nothing that may not come up for treatment by one of these three kinds of rhetoric.

A very few critics have raised the question as to what may be the instrument of oratory. My definition of an instrument is that without which the material cannot be brought into the shape necessary for the effecting of our object. But it is not the art which requires an instrument, but the artist. Knowledge needs no instruments, for it may be complete although it produces nothing, but the artist must have them. The engraver cannot work without his chisel nor the painter without his brush. I shall therefore defer this question until I come to treat of the orator as distinct from his art.
