We shall win a favourable hearing for ourselves and an unfavourable one for our opponents if, as in persuasion and dissuasion, we show briefly how we ourselves (or our friends) have benefited or are benefiting or will benefit those who are now seeking to wrong us (or those for whom they care); and point out to them that now is the opportunity to show us gratitude for our good services; and also, when it is possible, induce them to pity us.
