ABSTRACT. Botha notes that metaphors are pervasive both in thought and in language and in human subjective experience in general: in conceptual metaphor theory metaphors are analyzed as stable and systematic relation- ships between two conceptual domains. Mittelberg explores the semiotic work gestures perform in visualizing abstract concepts and structures, insisting on the different types of iconic modes discernable in gestural representations of the metaphorically conceptualized domain of grammar. Evans considers the cognitive preadaptations that may have paved the way for the emergence of semantic knowledge. pp. 353–358
