A Tale of a Tub
A Tale of a Tub was the first major work written by Jonathan Swift, arguably his most difficult satire and perhaps his most masterly. The "Tale" is a prose parody divided into sections each delving into the morals and ethics of the English. Composed between 1694 and 1697, it was eventually published in 1704. It was long regarded as a satire on religion, and has famously been attacked for that, starting with William Wotton.
Sweetness and light
Jonathan Swift first used the phrase in his mock-heroic prose satire, "The Battle of the Books" (1704), a defense of Classical learning (1704), which he published as a prolegomenon to his "A Tale of a Tub". It gained widespread currency in the Victorian era, when English poet and essayist Matthew Arnold picked it up as the title of the first section of his 1869 book "Culture and Anarchy: An Essay in Political and Social Criticism", where "sweetness and light" stands for beauty and intelligence, the two key components of an excellent culture.
