Abstract

This chapter set outs the variety of eighteenth-century approaches to the relations between language and thought, beginning with post-Lockean debates focused on the status of abstract general ideas, and ending with anti-empiricist Scottish philosophy at the end of the century. The empiricist theory of signs, notably in George Berkeley, is one important dimension of the discussions: ‘Ideas’ are centre stage, although they do not exhaust the empiricist furniture of the mind. There is also a different philosophical trend illustrated by neglected figures, which may be termed Platonic, and which affects eighteenth-century philosophical conceptions of language. The project of conjectural histories of language and views about the connections between linguistic skills and the social nature of human beings are also covered.
