Book 6
1.27
if we wish to give our words the appearance of sincerity, we must assimilate ourselves to the emotions of those who are genuinely so affected, and our eloquence must spring from the same feeling that we desire to produce in the mind of the judge. Will he grieve who can find no trace of grief in the words with which I seek to move him to grief? Will he be angry, if the orator who seeks to kindle his anger shows no sign of labouring under the emotion which he demands from his audience? Will he shed tears if the pleader's eyes are dry? It is utterly impossible.
1.28
Fire alone can kindle, and moisture alone can wet, nor can one thing impart any colour to another save that which it possesses itself. Accordingly, the first essential is that those feelings should prevail with us that we wish to prevail with the judge, and that we should be moved ourselves before we attempt to move others.
1.29
But how are we to generate these emotions in ourselves, since emotion is not in our own power? I will try to explain as best I may. There are certain experiences which the Greeks call φαντασίαι, and the Romans visions, whereby things absent are presented to our imagination with such extreme vividness that they seem actually to be before our very eyes.
