Rhetoric

BOOK I

Part 1

Rhetoric is the counterpart of Dialectic. Both alike are concerned

with such things as come, more or less, within the general ken of

all men and belong to no definite science. Accordingly all men make

use, more or less, of both; for to a certain extent all men attempt

to discuss statements and to maintain them, to defend themselves and

to attack others. Ordinary people do this either at random or through

practice and from acquired habit. Both ways being possible, the subject

can plainly be handled systematically, for it is possible to inquire

the reason why some speakers succeed through practice and others spontaneously;

and every one will at once agree that such an inquiry is the function

of an art.

Now, the framers of the current treatises on rhetoric have constructed

but a small portion of that art. The modes of persuasion are the only

true constituents of the art: everything else is merely accessory.

These writers, however, say nothing about enthymemes, which are the

substance of rhetorical persuasion, but deal mainly with non-essentials.

The arousing of prejudice, pity, anger, and similar emotions has nothing

to do with the essential facts, but is merely a personal appeal to

the man who is judging the case. Consequently if the rules for trials

which are now laid down some states-especially in well-governed states-were

applied everywhere, such people would have nothing to say. All men,

no doubt, think that the laws should prescribe such rules, but some,

as in the court of Areopagus, give practical effect to their thoughts

and forbid talk about non-essentials. This is sound law and custom.

It is not right to pervert the judge by moving him to anger or envy

or pity-one might as well warp a carpenter's rule before using it.

Again, a litigant has clearly nothing to do but to show that the alleged

fact is so or is not so, that it has or has not happened. As to whether

a thing is important or unimportant, just or unjust, the judge must

surely refuse to take his instructions from the litigants: he must

decide for himself all such points as the law-giver has not already

defined for him.

Now, it is of great moment that well-drawn laws should themselves

define all the points they possibly can and leave as few as may be

to the decision of the judges; and this for several reasons. First,

to find one man, or a few men, who are sensible persons and capable

of legislating and administering justice is easier than to find a

large number. Next, laws are made after long consideration, whereas

decisions in the courts are given at short notice, which makes it

hard for those who try the case to satisfy the claims of justice and

expediency. The weightiest reason of all is that the decision of the

lawgiver is not particular but prospective and general, whereas members

of the assembly and the jury find it their duty to decide on definite

cases brought before them. They will often have allowed themselves

to be so much influenced by feelings of friendship or hatred or self-interest

that they lose any clear vision of the truth and have their judgement

obscured by considerations of personal pleasure or pain. In general,

then, the judge should, we say, be allowed to decide as few things

as possible. But questions as to whether something has happened or

has not happened, will be or will not be, is or is not, must of necessity

be left to the judge, since the lawgiver cannot foresee them. If this

is so, it is evident that any one who lays down rules about other

matters, such as what must be the contents of the 'introduction' or

the 'narration' or any of the other divisions of a speech, is theorizing

about non-essentials as if they belonged to the art. The only question

with which these writers here deal is how to put the judge into a

given frame of mind. About the orator's proper modes of persuasion

they have nothing to tell us; nothing, that is, about how to gain

skill in enthymemes.

Hence it comes that, although the same systematic principles apply

to political as to forensic oratory, and although the former is a

nobler business, and fitter for a citizen, than that which concerns

the relations of private individuals, these authors say nothing about

political oratory, but try, one and all, to write treatises on the

way to plead in court. The reason for this is that in political oratory

there is less inducement to talk about nonessentials. Political
