Institutio Oratoria

For it is most important that we should know how the judge is disposed to listen, and his face will often (as Cicero [*](Not in any extant work.) reminds us) serve as a guide to the speaker. Consequently we must press the points that we see commend themselves to him, and draw back from those which are ill-received, while our actual language must be so modified that he will find our arguments as intelligible as possible. That this should be necessary is scarcely surprising, when we consider the alterations that are frequently necessary to suit the characters of the different witnesses.
