Sentence:  ...one <WSD>supermetaphor</WSD>. Perhaps we could steal a phrase from Merleau-Ponty and suggest that there are no principal and subordinate metaphors: all metaphors are concentric, like the concentricity of flesh, a metaphor for which there are no names in traditional philosophy. 
Meaning of the word marked with <WSD> tags:  An overarching metaphor; a metaphor that encompasses several sub-metaphors.
