Book excerpt: In his ten Beijing lectures, Leonard Talmy represents the range of his work in cognitive semantics. The central concern of this approach is the linguistic representation of conceptual structure, that is, the patterns in which and processes by which conceptual content is organized in language. The lectures examine the semantics of grammar, force dynamics, a typology of how motion events are represented, factive versus fictive motion, a typology of event integration, differences in how spoken and signed language structure space, the attention system of language, introspection as a methodology in linguistics, the relation of language to other cognitive systems, and digitalization in the Evolution of language.
