1I. Ad omnem iudicialem causam quemadmodum conveniret inventionem rerum adcommodari satis abundanter arbitror superioribus libris demonstratum. Nunc earum rationem rerum inveniendarum quae pertinebant ad causas deliberativas et demonstrativas in hunc librum transtulimus, ut omnis inveniendi praeceptio tibi quam primum persolveretur.
Reliquae quattuor partes erant artificii. De tribus partibus in hoc libro dictum est: dispositione, pronuntiatione, memoria. De elocutione, quia plura dicenda videbantur, in quarto libro conscribere maluimus, quem, ut arbitror, tibi librum celeriter absolutum mittemus, ne quid tibi rhetoricae artis deesse possit. Interea prima quaeque et nobiscum cum voles, et interdum sine nobis legendo consequere, ne quid inpediare quin ad hanc utilitatem pariter nobiscum progredi possis. Nunc tu fac adtentum te praebeas; nos proficisci ad instituta pergemus.

Four departments of rhetoric are left us to consider. Three are treated in the present Book: Arrangement,b Delivery,c and Memory.d Style, because it seems to require a fuller treatment, I prefer to discuss in Book IV,e which I hope to complete quickly and send to you, so that you may not lack anything on the art of rhetoric. Meanwhile you will learn all the principles I first set forth,f with me, when you wish, and at times without me, by reading, so that you may in no way be kept from equal progress with me towards the mastery of this useful art. It is now for you to give attention, while I resume progress towards our goal.
2II. Deliberativeg speeches are either of the kind in which the question concerns a choice between two courses of action, or of the kind in which a choice among several is considered. An example of a
