Conceptual Metaphor Home Page, maintained by George Lakoff [via MeFi] (a list of all metaphors). Superb. This is proper deep-level stuff, how we live and relate to the universe and each other. Playing with how a counterfactual metaphor could come to be would be an interesting exercise. Although at the moment I'm more interested in coherency, the idea that disparate metaphors align. You can see this in our industrial world, individuals living their lives coherent with the concept that they're a self-contained step, that they should follow the letter of their explicit instructions and let everything else go because someone higher up must be looking after that.
