Abstract

Pepper’s concept of a root metaphor possesses profound implications for any theory that attempts to explain language, especially those theories that try to construct explanatory accounts of ambiguity and metaphor. Any explanatory theory of metaphor must as a theory necessarily be metaphorical in the sense of presupposing a root metaphor. But this discovery does not mean that all language is metaphorical; there can be literal language even though metalinguistic accounts of language including metaphor must be founded upon root metaphors.
