I'm going to be pretty critical here.

Problem 1: Just-so stories. There are stories told about many of the metaphors based only on guesses, which result in occasional inaccuracy. For example, "stand up to something" comes from fistfights, not a general tendency to see up as good.

Problem 2: Commonplace facts, or facts leading nowhere. For example, in English we often use the metaphor of life as a journey. We know this already. What should we do with it?

If the parts exhibiting these problems were eliminated from the post as it is now, you'd basically be left with bits of the introduction, one example of a common metaphor, the bit on Zeno's arrow, and the last ten lines. Not very much. Something I'd like to see an example of is change in non-moral ideas resulting in a change in moral behavior that uses the non-moral ideas as a metaphor, and implications for the project of trying to isolate "human morality."
