Abstract
The unit of metaphor isn’t always a complete sentence; often it is a single word or phrase. In such a case, the word or phrase in question makes a nonstandard, metaphorically determined contribution to the propositional content of the sentence in which it appears, a content whose other ingredients are determined in routine ways by routine recursive procedures of truth-conditional semantics. In this respect, metaphor belongs to semantics. In other respects, it doesn’t belong to semantics at all. To identify what Yeats contributed to the content of his own sentence when he wrote.
