"Ruth Millikan's project is nothing less than a complete account of signs-animal and human, natural and intentional, public and inner-and it is wonderfully realized, carefully argued, and richly exemplified. Varieties of Meaning is essential and engrossing reading for philosophers of mind, cognitive psychologists and linguists, and for everyone else who cares about how we think and communicate."
-- Robyn Carston, University College London

Many different things are said to have meaning: people mean to do various things; tools and other artifacts are meant for various things; people mean various things by using words and sentences; natural signs mean things; representations in people's minds also presumably mean things. In Varieties of Meaning, Ruth Garrett Millikan argues that these different kinds of meaning can be understood only in relation to each other.
