Fauconnier and Turner's chapter outlines recent theoretical advances on metaphor within conceptual blending theory ("Rethinking Metaphor"). Through a detailed analysis of the TIME is SPACE metaphor, they demonstrate how metaphor interpretation requires elaborate integration networks and various techniques for building particular networks such as cobbling and sampling, compression, emergent structure, and overarching goals. These permanent features of cognition are not special to metaphor but can give rise to counterfactuals, analogies, categorizations, and metonymies. Nonetheless, the general framework of conceptual blending theory is capable of explicating various complexities of metaphorical thought and meaning that are difficult to describe within more traditional theories.
