Jonathan Swift's A Modest Proposal

A Modest Proposal for Preventing the Children of Poor People From Being a Burden to Their Parents or Country, and for Making Them Beneficial to the Publick, commonly referred to as A Modest Proposal, is a Juvenalian satirical essay written and published anonymously by Jonathan Swift in 1729. Swift suggests that the impoverished Irish might ease their economic troubles by selling their children as food for rich gentlemen and ladies. This satirical hyperbole mocks heartless attitudes towards the poor, as well as Irish policy in general.
In English writing, the phrase "a modest proposal" is now conventionally an allusion to this style of straight-faced satire.

Jonathan Swift (30 November 1667 – 19 October 1745) was an Anglo-Irish satirist, essayist, political pamphleteer (first for the Whigs, then for the Tories), poet and cleric who became Dean of St Patrick's Cathedral, Dublin.He is remembered for works such as Gulliver's Travels, A Modest Proposal, A Journal to Stella, Drapier's Letters, The Battle of the Books, An Argument Against Abolishing Christianity, and A Tale of a Tub. Swift is probably the foremost prose satirist in the English language, and is less well known for his poetry. He is also known for being a master of two styles of satire: the Horatian and Juvenalian styles.
