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.
