A Tale of a Tub
The first, second, and third editions of the "Tale" appeared in 1704; the fifth edition came out in 1710. In "The Apology for the &c.", Swift indicates that he originally gave his publisher a preliminary copy of the work, while he kept a blotted copy at his own hand and lent other copies including one to Thomas Swift, Jonathan's "parson cousin". As a consequence, the first edition appeared with many errors. The second edition was a resetting of the type. The third edition was a reprint of the second, with corrections, and the fourth edition contained corrections of the third.
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.
