Book 11
1.1
After acquiring the power of writing and thinking, as described in the preceding book, and also of pleading extempore, if occasion demand, our next task will be to ensure that appropriateness of speech, which Cicero De Or. III. x. 37. shows to be the fourth department of style, and which is, in my opinion, highly necessary.
1.2
For since the ornaments of style are varied and manifold and suited for different purposes, they will, unless adapted to the matter and the persons concerned, not merely fail to give our style distinction, but will even destroy its effect and produce a result quite the reverse of that which our matter should produce. For what profit is it that our words should be Latin, significant and graceful, and be further embellished with elaborate figures and rhythms, unless all these qualities are in harmony with the views to which we seek to lead the judge and mould his opinions?
