Conduct books integrated the styles and rhetoric of earlier genres, such as devotional writings, marriage manuals, recipe books, and works on household economy. They offered their readers a description most often of the ideal woman, while at the same time handing out practical advice. Not only did they dictate morality, but they guided readers' choice of dress and outlined what was seen in that period as proper etiquette. Chapone's work in particular appealed to Wollstonecraft and influenced her composition of "Thoughts". She admired it for its "sustained programme of study for women" and basis on the idea that Christianity should be "the chief instructor of our rational faculties". and on its emphasis that women should be considered rational beings and not left to wallow in "sensualism". Wollstonecraft drew on both Chapone and Macaulay's works when she wrote "A Vindication of the Rights of Woman" in 1792. Another admirer, and also a personal friend, was the novelist and diarist Frances Burney. Their surviving correspondence includes a letter of condolence of 4 April 1799 from Burney to Chapone, on the death in childbirth of Jane Jeffreyes, née Mulso, the niece to whom the "Letters on the Improvement of the Mind" had been addressed.
