The theory of signifying (significs), formulated and introduced by Victoria Welby for the first time in 1890s, is at the basis of much of 20th-century linguistics, as well as in other language and communication sciences such as sociolinguistics, psycholinguistics, translation theory and semiotics. Indirectly, the origins of approaches, methods and categories elaborated by analytical philosophy, Wittgenstein himself, Anglo-American speech act theory, and pragmatics are largely found with Victoria Lady Welby. Indeed, it is no exaggeration to say that Welby is the ""founding mother"" of semiotics.

Brain, Mind and the Signifying Body is an exploration of a multimodal theory of cognitive science. Using linguistic theories first developed by Saussure and more latterly by M. A. K. Halliday, Paul Thibault analyses how social and biological systems interact to produce meaning. This fascinating study will be of interest to undergraduates and academics researching cognitive linguistics and advanced semiotics. The book engages with the current dialogue between the human and life sciences to ask questions about the relationship between the physical, biological aspects of a human being, and the sociocultural framework in which a human being exists.
