I recently read James Geary’s entertaining book I Is an Other–The Secret Life of Metaphor and How It Shapes the Way We See the World. Geary takes his title from one of Rimbaud‘s letters, calling this phrase metaphor’s “principal equation”:
Metaphor systematically disorganizes the common sense of things–jumbling together the abstract with the concrete, the physical with the psychological, the like with the unlike–and reorganizes it into uncommon combinations.
I like this definition because it feels more complete than the typical definition of metaphor as a comparison without the use of the adverbial comparative (i.e., no “like” or “as”). Indeed, metaphor probably forms the basis of language itself; while that conclusion’s much debated in semiotics, linguistics, and other scholarly disciplines, common sense and common usage strongly suggest that even thought itself–in terms of how we think internally about the world–employs metaphor as an underpinning.
Maybe I believe so because I’m a poet. Geary, as it turns out, has written some poetry, though he’s best known for his books about words, word origins, wordplay, aphorisms, witticisms, and the like. (He’s also got a TED talk…everybody’s got a TED talk…)
As to poetry, and how metaphor behaves in the poem’s context, I like what Geary says here (although in this excerpt it’s not actually poetry he’s discussing, but rhetoric):
Readers actively retrieve a metaphor’s meaning, just as a punch line requires listeners to resolve a joke’s incongruities for themselves…though the speaker may make the metaphor, the hearer makes its meaning. Hearer and speaker are accomplices; the one unpacks what the other presents. In terms of creativity, producing a metaphor and penetrating one are almost the same act.
I think the above lines go far to explaining why I love to read poetry and also provide implications as to why poems can be so damned difficult to compose. The poet endeavors to create a context and container for an often-unknown audience who will nonetheless need to invest, one hopes willingly, in the process of reorganizing the surprising (metaphor) into the recognizable.
And what a fine task that is!
