Institutio Oratoria

Quintus Hortensius deserves the high praise which has been awarded him for the care which he took over his partitions, although Cicero more than once indulges in kindly mockery of his habit of counting his headings on his fingers. For there is a limit to gesture, and we must be specially careful to avoid excessive minuteness and any suggestion of articulated structure in our partition. If our divisions are too small,

they cease to be limbs and become fragments, and consequently detract not a little from the authority of our speech. Moreover, those who are ambitious of this sort of reputation, in order that they may appear to enhance the nicety and tile exhaustive nature of their division, introduce what is superfluous and subdivide things which naturally form a single whole. The result of their labours is, however, not so much to increase the number of their divisions as to diminish their importance, and after all is done and they have split up their argument into a thousand tiny compartments, they fall into that very obscurity which the partition was designed to eliminate.

The proposition, whether single or multiple, must, on every occasion when it can be employed with profit, be clear and lucid; for what could be more discreditable than that a portion of the speech, whose sole purpose is to prevent obscurity elsewhere, should itself be obscure? Secondly it must be brief and must not be burdened with a single superfluous word; for we are not explaining what we are saying, but what we are going to say.

We must also ensure that it is free alike from omissions and from redundance. Redundance as a rule occurs through our dividing into species when it would be sufficient to divide into genera, or through the addition of species after stating the genus. The following will serve as an example:

I will speak of virtue, justice and abstinence.

Our first partition will be between admitted and disputed facts. Admitted facts will then be divided into those acknowledged by our opponent and those acknowledged by ourselves. Disputed facts will be divided into those which we and those which our opponents allege. But the worst fault of all is to treat your points in an order different from that which was assigned them in your proposition.
