'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 contemporaryconcerns. 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. The background tothese contentions is outlined in Chapter One, in which Edward Nye traces the rise of the term 'nuances' as an attempt by contemporary authors to understand representation in art as a rationalization of chaotic reality. The demise of these contentions at the end of the century is described in thelast chapter, in which the dominant language theory of the day, ideologie, is shown to be antagonistic to the study of art and literature. Theories of language are no longer an answer to the question 'what is beauty?'
