Metaphorical use of language differs in significant ways from literal use but is no less comprehensible, no more recondite, no less practical, and no more independent of truth or falsity that is literal use. Far from being a mere matter of ornament, it participates fully in the progress of knowledge: in replacing some stale “natural” kinds with novel and illuminating categories, in contriving facts, in revising theory, and in bring us new worlds.
— “Metaphor as Moonlighting” - Of Mind and Other Matters, Nelson Goodman (via cdixon)
