angement of
his, when he intended to mention only classes, he has joined also a
mention of a subordinate division. For covetousness is the general
class under which all desires are comprehended, and beyond all
question avarice is a subordinate division of that class.

We must therefore avoid, after having mentioned a universal class,
then, in the same arrangement, to mention along with it any one of
its subordinate divisions, as if it were something different and
dissimilar. And if there are many subordinate divisions to any
particular class, after that has been simply explained in the first
arrangement of the oration, it will be more easily and conveniently
arranged when we come to the subsequent explanation in the general
statement of the case after the division. And this, too, concerns the
subject of conciseness, that we should not undertake to prove more
things than there is any occasion for, in this way--"I will prove that
the opposite party were able to do what we accuse them of, and had the
inclination to do it, and did it." It is quite enough to prove that
they did it. Or when there is no natural division at all in a cause,
and when it is a simple question that is under discussion, though that
is a thing which cannot be of frequent occurrence, still we must use
careful arrangement. And these other precepts also, with respect to
the division of subjects which have no such great connexion with the
practice of orators, precepts which come into use in treatises in
philosophy, from which we have transferred, hither those which
appeared to be suitable to our purpose, of which we found nothing in
the other arts. And in all these precepts about the division of our
subjects, it will throughout our whole speech be found that every
portion of them must be discussed in the same order as that in which
it has been originally stated, and then, when everything has been
properly explained, let the whole be summed up, and summed up so that
nothing be introduced subsequently besides the conclusion. The old
man in the Andria of Terence arranges briefly and conveniently the
subjects with which he wishes his freedman to become acquainted--

"And thus the life and habits of my son
And my designs respecting his career,
And what I wish your course towards both to be,
Will be quite plain to you."

And accordingly, as he has proposed in his original arrangement, he
proceeds to relate, first the life of his son--

"Fo
