Book 10
5.5
But I would not have paraphrase restrict itself to the bare interpretation of the original: its duty is rather to rival and vie with the original in the expression of the same thoughts. Consequently, I disagree with those who forbid the student to parahrase speeches of our own orators, on the ground that, since all the best expressions have already been appropriated, whatever we express differently must necessarily be a change for the worse. For it is always possible that we may discover expressions which are an improvement on those which have already been used, and nature did not make eloquence such a poor and starveling thing, that there should be only one adequate expression for any one theme.
5.6
It can hardly be argued that, while the gestures of the actor are capable of imparting a wealth of varied meaning to the same words, the power of oratory is restricted to a narrower scope, so that when a thing has once been said, it is impossible to say anything else on the same theme. Why, even if it be granted that no new expression we discover can be better than or even equal to the old, it may, at any rate, be a good second.
