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.
It can hardly be argued that, while the gestures of the actor are capable of imparting a wealth of varied meaning
Do we not often speak twice, or even more frequently, on the same subject, sometimes even to the extent of a number of sentences in succession? It will scarce be asserted that we must not match ourselves against others when we are permitted to match ourselves against ourselves. For if there were only one way in which anything could be satisfactorily expressed, we should be justified in thinking that the path to success had been sealed to us by our predecessors. But, as a matter of fact, the methods of expression still left us are innumerable, and many roads lead us to the same goal.
Brevity and copiousness each have their own peculiar grace, the merits of metaphor are one thing and of literalness another, and, while direct expression is most effective in one case, in another the best result is gained by a use of figures. Further, the exercise is valuable in virtue of its difficulty; and again, there is no better way of acquiring a thorough understanding of the greatest authors. For, instead of hurriedly running a careless eye over their writings, we handle each separate phrase and are forced to give it close examination, and we come to realise the greatness of their excellence from the very fact that we cannot imitate them.
