 When it comes to metaphorical truth: there can be truth (call it metaphorical truth) in a sentence that is itself, considered simply as a sentence, simply false, just as there can be truth (call it mythic truth) in a story that is itself, considered simply as a story, simply false. Understood along these lines, metaphorical truth would be something like the revelatory power conferred upon a metaphorical sentence (or on the impulse to use such a sentence) by a successful metaphorical interpretation of the sentence, a successful ascription to it of metaphorical meaning.
