Wollstonecraft relies extensively on the language of the sublime in "Letters Written in Sweden, Norway, and Denmark". She draws on and redefines Edmund Burke's central terms in "A Philosophical Enquiry into the Origin of Our Ideas of the Sublime and Beautiful" (1757). Burke privileges the sublime (which he associates with masculinity, terror, awe, and strength) over the beautiful (which he associates with femininity, passivity, delicacy, and weakness), while Wollstonecraft ties the sublime to sterility and the beautiful to fertility. For her, the beautiful is connected to the maternal; this aesthetic shift is evident, for example, in the many passages focusing on the affectionate tie between Wollstonecraft and little Fanny, her daughter. She thus claims the feminine category of the "beautiful" for the most virtuous and useful of women: mothers.
