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.

But for the orator it will be sufficient to say,

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

v4-6 p.365

when the orator may lawfully employ the syllogism, I am far from desiring him to make his whole speech consist of or even be crowded with a mass of epicheiremes and enthymemes. For a speech of that character would resemble dialogues and dialectical controversies rather than pleadings of the kind with which we are concerned, and there is an enormous difference between the two.

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.
