Abstract

The paper analyzes the cognitive functions of metaphors present in both colloquial and scientific discourse. First, presented is the history of research into linguistic metaphors, followed by a discussion of the psycholinguistic turn towards metaphors as thought schemas, as well as metaphoricality embodied in gestures, images and behaviors and their socio-cultural contexts. Based on the analysis of metaphors in the natural sciences, mainly in physics as well as in psychology, the heuristic and methodological functions of metaphors in science are discussed. Finally, on this basis, a general model of the cognitive functions of metaphor is constructed in which, apart from the cognitive communicative functions, emphasized are also the pragmatic aspects of metaphorical thinking.
