I’ve been thinking about metaphor. But to talk about it, I have to at least mention simile. As I understand it, a simile is simply a comparison: something is like something else. And usually, at least in literature, similes are used to link something concrete to something abstract, like a feeling or an idea. Although there’s a big difference between a rose and a feeling, a simile can suggest what the feeling is like by comparing it with the rose. For example: My love is like a red, red rose. Something of how we respond to roses, their beauty, their colour, gets linked to a feeling: love. And in that comparison we pass meaning to someone else, however fuzzy the translation may be.
Metaphor is different. It doesn’t develop a comparison, it establishes an identity. One thing is another thing. Consider what happens if I change the line we’re using to the following: My love is a red, red rose. The sentence says that the rose is his love, it’s identified with it. And that’s a different thing altogether. A simile, based in comparison, is logical enough for us. A metaphor, on the other hand, requires more since it makes the abstraction and the object a single reality. It’s not an objective correlative, an object used to suggest a feeling. It’s a fusion of the two.
Metaphor is more than simile because
