Book 3
5.25
Still we do not keep our attention rigidly fixed on such details, but the desire to win praise by any available means and the sheer delight in speaking make us wander away from the subject, since there is always richer material for eloquence outside the strict theme of the case, inasmuch as the points of any given dispute are always few, and there is all the world outside, and in the one case we speak according to our instructions, in the other on the subjects of our own choice.
5.26
We should teach not so much that it is our duty to discover the question, the central argument, and the point for the decision of the judge (an easy task), as that we should continually keep our attention on our subject, or if we digress, at least keep looking back to it, lest in our desire to win applause we should let our weapons drop from our grasp.
