The Real Metaphoric Formula

Metaphor is supposed to state the unknown in terms of the known. It is supposed to say X equals Y. Yet when we say “John is a lion,” we do not think of John with a mane, with four clawed paws, nor with a pompon tipped tail. We extract from “lion” the emotional equivalent we need and let the rest go. The real metaphoric formula is X does-and-does-not-equal Y.
