Institutio Oratoria

But such a practice will be fatal in the courts, where we have to answer our opponent and not ourselves. It is said that Accius, when asked why he did not turn advocate in view of the extraordinary skill in making apt replies which his tragedies revealed, replied that in his plays the characters said what he himself wanted them to say, whereas in the courts his adversaries would probably say just what he least wanted them to say.

It is therefore ridiculous in exercises which prepare the student for the actual courts to consider what answer can be made before ever giving a thought to what the opposing counsel is likely to say. And a good teacher should commend a pupil no less for his skill in thinking out arguments that may be put forward for the opposite side than in discovering arguments to prove his own case.

Again, there is another practice which is always permissible in the schools, but rarely in the courts. For when we speak first as claimants in a real case, how can we raise objections, seeing that our opponent has so far said nothing?
