Metaphor is central to cognition

Metaphor can be seen as something much more central to thought than a colorful figure of speech in literature. Metaphorical thought helps us find parallels, not only among concepts, but even between concepts and sensorimotor modalities, as physical and conceptual space are coded in the same region. The concept of conceptual parallel is itself a metaphor (matching patterns of relation), as is metaphor itself (“carrying over”, like a bridge). At the extreme, Hofstadter, Lakoff, and Johnson argue that metaphor based on embodiment is central to child development, abstract reasoning, and everything in between. In their view, cross-domain projection of invariant mental models is key to general intelligence.
