Book 10
1.28
But the man who to these good qualities adds his own, that is to say, who makes good deficiencies and cuts down whatever is redundant, will be the perfect orator of our search; and it is now above all times that such perfection should be attained when there are before us so many more models of oratorical excellence than were available for those who have thus far achieved the highest success. For this glory also shall be theirs, that men shall say of them that while they surpassed their predecessors, they also taught those who came after.
3.1
Such are the aids which we may derive from external sources; as regards those which we must supply for ourselves, it is the pen which brings at once the most labour and the most profit. Cicero is fully justified in describing it as the best producer and teacher of eloquence, and it may be noted that in the de Oratore De Or. i. 150. he supports his own judgment by the authority of Lucius Crassus, in whose mouth he places this remark.
3.2
We must therefore write as much as possible and with the utmost care. For as deep ploughing makes the soil more fertile for the production and support of crops, so, if we improve our minds by something more than mere superficial study, we shall produce a richer growth of knowledge and shall retain it with greater accuracy. For without the consciousness of such preliminary study our powers of speaking extempore will give us nothing but an empty flow of words, springing from the lips and not from the brain.
