Irony, by its definition, is a rhetorical device or literary technique that conveys a subterranean meaning that is exactly opposite to the literal meaning of its obvious words. Writers tend to employ such a technique to provoke reconsiderations from readers about the problem posed by the writer. Jonathan Swift, in his book A Modest Proposal, launches what he calls a "modest proposal", quite horrible and inhumane, to solve the problem of poverty. Mark Twin also expresses his enthusiastic and patriotic emotion towards the war in his work The War Prayer. However, none of these superficial statements from Swift and Twin match their true intentions, which are covered up by the obvious words and implied by the writers. In Jonathan Swift's A Modest Proposal, the persona – a persona assumed by an author in a written work – is different from Swift (author) himself. The character in Swift's pamphlet is used to present the atrocious idea of ​​the "modest proposition"—eating babies—so that readers say, "What a horrible idea?" Are you serious about this? and then make readers rethink what the unstated true intention is. For example, the character says: "I recommend rather buying the children alive and dressing them hot with a knife as we do when roasting pigs" (860) and "the fore or hind quarter will make a reasonable dish, and seasoned with a little paper. or the salt will be very good” (860). In these cruel and inhumane words, he describes “papist” babies as commodities rather than human beings. He estimates the economic profit that babies could make without any compassion or pity. In fact, these extremely brutal and anti-human statements made by a character are, indeed, Swift's (the author) sarcastic revolt and contempt towards the unjust world...... middle of paper...... m who is the source of love, and who is the refuge and ever faithful friend of all who are afflicted and seek his help with a humble and contrite heart. Amen. »Even though Swift and Twin employ irony in their works, the way they use it is different. Swift's modest proposal sounds more like sarcastic irony and is more explicit. ……the good gentleman would not hesitate to pay more than a penny for the gloves. However, Mark Twin's irony in A War Prayer is much more explicit than Swift's in A Modest Proposal. Someone who does not know much about the historical context of the war may consider the narrator's chauvinistic view to be equivalent to Twin's value toward the war. Additionally, another difference in the use of irony between Swift and Twin is that Swift does not mention his true intention, whereas Twin somehow expresses his views on war through the old stranger..
