Pope, Verses ll. Irony is a disagreement or incongruity between what is said and what is understood, or what is expected and what actually occurs. It argues that their lot as scribes is not only useful, but far superior to that of the ordinary man.
As in the case of Aristophanes plays, menippean satire turned upon images of filth and disease. Satire usually implies the use of irony or sarcasm for censorious or critical purposes and is often directed at public figures or institutions, conventional behavior, political situations, etc.
Ambiguity is likewise useful because the intention can always be denied, but it also serves to make the satiric comparison more pointed, by making difficult any distinction between the target and the object to which it is compared.
However, the main function of humour is to momentarily amuse the reader or audience member. To invite readers to reflect on their own weaknesses and shortcomings.
The ironic form of simile, used in sarcasm, and some forms of litotes can emphasize one's meaning by the deliberate use of language which states the opposite of the truth, denies the contrary of the truth, or drastically and obviously understates a factual connection.
For example, satire is often used to achieve political or social change, or to prevent it.
