 Although nothing in Rosch’s experiments licensed the conclusion that prototypical rankings should be reified and treated as the content of concepts (what her experiments did support was merely that a theory of the mental representation of categories should be consistent with the existence of prototype effects), the study of prototypes revolutionized the existing approaches to category concepts (Murphy 2002) and was a leading force behind the birth of cognitive linguistics. Prototypes were central to the development of the Radial Network Theory of Brugman (1988 [1981]) and Lakoff (Brugman &amp; Lakoff 1988), which proposed to model the sense network of words by introducing in the architecture of word meanings the center-periphery relation at the heart of Rosch’s seminal work. According to Brugman, word meanings can typically be modeled as radial complexes where a dominant sense is related to less typical senses by means of semantic relations such as metaphor and metonymy. For example, the sense network of ‘fruit’ features product of plant growth at its center and a more abstract outcome at its periphery, and the two are connected by a metaphorical relation). On a similar note, the Conceptual Metaphor Theory of Lakoff &amp; Johnson (1980; Lakoff 1987) and the Mental Spaces Approach of Fauconnier (1994; Fauconnier &amp; Turner 1998) combined the assumption that word meanings typically have an internal structure arranging multiple related senses in a radial fashion, with the further claim that our use of words is governed by hard-wired mapping mechanisms that catalyze the integration of word meanings across conceptual domains. For example, it is in virtue of these mechanisms that the expressions “love is war”, “life is a journey”) are so widespread across cultures and sound so natural to our ears. On the proposed view, these associations are creative, perceptually grounded, systematic, cross-culturally uniform, and grounded on pre-linguistic patterns of conceptual activity which correlate with core elements of human embodied experience (see the entries on  metaphor  and  embodied cognition).
