"Linguistic" theories in the eighteenth-century are also theories of literature and art, and it is probably better, therefore, to think of them as "aesthetic" theories. As such, they are answers to the age-old question "what is beauty?," but formulated, also, to respond to contemporary concerns. Edward Nye considers a wide range of authors from these two perspectives and draws the following conclusions: etymology is a theory of poetry, dictionaries of synonymy, prosody and metaphor are theories of preciosity, and Sensualism is a theory of artistic representation.
