Institutio Oratoria

But when a reason of unusual length intervenes, it is necessary to state the final conclusion, otherwise the major premise and the reason would suffice.

Laws are silent in the midst of arms, and do not require us to await their sanction when the circumstances are such that he who would await their sanction is certain to be the victim of an unjust penalty before ever the just penalty can be claimed.

The laws are silent in the midst of arms.

We may also begin with the reason and then proceed to the conclusion as in another passage from the same speech [*](ib. iii. 9. ) :

But if the Twelve Tables permitted the killing of a thief by night under any circumstances, and by day if he used a weapon to defend himself, who is there who will contend that the slayer must be punished under whatever circumstances a man has been killed?

When he sees that the sword is sometimes placed in our hands by the laws themselves.

On the other hand, he places the various parts in the regular order in the following instance:

How can it be unjust to kill a robber who lies in wait for his victim?

What is the object of our escorts and our swords?

Which we certainly should not be permitted to have, if we were absolutely forbidden to use them.

This form of proof may be countered in three ways, that is to say it may be attacked in all its parts. For either the major premise or the minor or the conclusion or occasionally all three are refuted. The major premise is refuted in the following case:

I was justified in killing him, as he lay in wait for me.

whether it is right that he who confesses that he has killed a man should look upon the light of day.

The minor premise is refuted by all the methods which we mentioned in dealing with refutation. [*](In the preceding chapter.) As to the reason it must be pointed out that it is sometimes true when the proposition to which it is attached is not true, but may on the other hand sometimes be false although the proposition is true. For example,

Virtue is a good thing

Because it brings us wealth,

With regard to the conclusion, we may either deny its truth when it infers something which does not logically result from the premises, or we may treat it as irrelevant. The truth is denied in the following case:

We are justified in killing one who lies in wait for us; for since, like an enemy, he threatens us with violence, we ought to repulse his attack as though he were an enemy: therefore Milo was justified in killing Clodius as an enemy.

But while the major premise and the reason

Some call the enthymeme a rhetorical syllogism, while others regard it as a part of the syllogism, because whereas the latter always has its premises and conclusion and effects its proof by the employment of all its parts, the ethymeme is content to let its proof be understood without explicit statement.

The following is an example of a syllogism:

Virtue is the only thing that is good, for that alone is good which no one can put to a bad use: but no one can make a bad use of virtue; virtue therefore is good.

Virtue is a good thing because no one can put it to a bad use.

Money is not a good thing; for that is not good which can be put to a bad use: money may be put to a bad use; therefore money is not a good thing.

Can money be a good thing when it is possible to put it to a bad use?

The following argument is couched in syllogistic form:

If money in the form of silver coin is silver, the man who bequeathed all his silver to a legatee, includes all money in the form of coined silver: but he bequeathed all his silver: therefore he included in the bequest all money in the form of coined silver.

Since he bequeathed all his silver, he included in his bequest all his silver money.

I think I have now dealt with all the precepts of those who treat oratory as a mystery. But these rules still leave scope for free exercise of the judgment. For although I consider that there are occasions

For in the former we are confronted with learned men seeking for truth among men of learning; consequently they subject everything to a minute and scrupulous inquiry with a view to arriving at clear and convincing truths, and they claim for themselves the tasks of invention and judgment, calling the former τοπική or the art of selecting the appropriate material for treatment, and the latter κριτική or the art of criticism.

We on the other hand have to compose our speeches for others to judge, and have frequently to speak before an audience of men who, if not thoroughly ill-educated, are certainly ignorant of such arts as dialectic: and unless we attract them by the charm of our discourse or drag them by its force, and occasionally throw them off their balance by an appeal to their emotions, we shall be unable to vindicate the claims of truth and justice.

Eloquence aims at being rich, beautiful and commanding, and will attain to none of these qualities if it be broken up into conclusive inferences which are generally expressed in the same monotonous form: on the contrary its meanness will excite contempt, its severity dislike, its elaboration satiety, and its sameness boredom.

Eloquence therefore must not restrict itself to narrow tracks, but range at large over the open fields. Its streams must not be conveyed

Must lie not vary and diversify it by a thousand figures, and do all this in such a way that it seems to come into being as the very child of nature, not to reveal an artificial manufacture and a suspect art nor at every moment to show traces of an instructor's hand? What orator ever spoke thus? Even in Demosthenes we find but few traces of such a mechanism. And yet the Greeks of to-day are even more prone than we are (though this is the only point in which their practice is worse than ours) to bind their thoughts in fetters and to connect them by an inexorable chain of argument, making inferences where there was never any doubt, proving admitted facts and asserting that in so doing they are following the orators of old, although they always refuse to answer the question who it is that they are imitating. However of figures I shall speak elsewhere. [*](IX. i. ii. iii.)

For the present I must add that I do not even agree with those who hold that arguments should always be expressed in language which is not only pure, lucid and distinct, but also as free as possible from all elevation and ornateness. I readily admit that

But if the subject be one of real importance every kind of ornament should be employed, so long as it does nothing to obscure our meaning. For metaphor will frequently throw a flood of light upon a subject: even lawyers, who spend so much trouble over the appropriateness of words, venture to assert that the word litus is derived from eludere, because the shore is a place where the waves break in play.

Further, the more unattractive the natural appearance of anything, the more does it require to be seasoned by charm of style: moreover, an argument is often less suspect when thus disguised, and the charm with which it is expressed makes it all the more convincing to our audience. Unless indeed we think that Cicero was in error when he introduced phrases such as the following into an argumentative passage:

The laws are silent in the midst of arms,

A sword is sometimes placed in our hands by the laws themselves.

I undertook my present task, Marcellus Victorius, mainly to gratify your request, [*](cp. Proem, Bk. I. ) but also with a view to assist the more earnest of our young men as far as lay in my power, while latterly the energy with which I have devoted myself to my labours has been inspired by the almost imperative necessity imposed by the office conferred on me, [*](cp. Proem, Bk. IV. ) though all the while I have had an eye to my own personal pleasure. For I thought that this work would be the most precious part of the inheritance that would fall to my son, whose ability was so remarkable that it called for the most anxious cultivation on the part of his father. Thus if, as would have been but just and devoutly to be wished, the fates had torn me from his side, he would still have been able to enjoy the benefit of his father's instruction.
