The satirist's most effective weapon is irony. Its aim is to defeat the opponent on his own ground by pretending to accept his premises, his values, his methods of reasoning, in order to expose their implicit absurdity. 'All animals are equal, but some are more equal than others.' Irony purports to take seriously what it does not; it enters into the spirit of the other person's game to demonstrate that its rules are stupid or vicious. It is a subtle weapon, because the person who wields it must have the imaginative power of seeing through the eyes of his opponent, of projecting himself into the other's mental world.
